Ye Yang estimated that the "life transformation" skill he obtained was actually a certain ability of the Holy Grail.

If the level of this skill continues to improve, I wonder if it will grow to a level comparable to the Holy Grail? For example, without the Holy Grail, you can turn the enemy into holy liquid or holy water by your own skills.

Ye Yang can look forward to it.

However, when he was ready to find the trouble of those dark creatures, Ji Yan stopped him and said that he would follow him this time.

"OK. However, you can follow me, but you can't do it without my consent... If it's on the ground and the sky is bright, I allow you to fight those dark creatures, but you can't do it underground."

There are too many dangers in this dark place. Unknown environment means unknown danger. Ji Yan is more powerful than Ye Yang in many aspects, but her life-saving ability is a little worse.

Although she also has the ability to predict danger, it is too dangerous compared with Ye Yang's whim.

If she encounters a frontal attack, she is basically not afraid, but if she encounters a sneak attack, her head, heart, abdomen and these parts are attacked, the risk is great.

"Well, what you say is what you say." Ji Yan didn't object to Ye Yang's opinion.

"Why do you have to follow me?"

"Because you took dozens of undead men out, none of them came back, and you slept all day as soon as you came back." Ji Yan said.

She is also worried about Ye Yang.

So Ye Yang didn't say much.

Drove over in another bulletproof car.

This car is not much in the underground space.

The space crack is not big.

To drive the bulletproof car in, you must dismantle it first and then get it in. A lot of things were handled like this before.

Some tanks can't be disassembled and are still stacked over the shelter.

At the moment, another car went out.

Ye Yang is not afraid that General Liu and company commander Zhao will sneak attacks on him and Ji Yan. The danger underground makes them dare not sneak attacks at such times. And many of their confidants are undead creatures transformed by Ye Yang. They won't let them mess around.

Soon, Ye Yang and Ji Yan arrived at the camp of dark creatures in a car carrying a small number of undead creatures.

From a distance, the dark creatures heard the movement here and poured in again.

As if they had forgotten the embarrassing scene of being killed and running away, now they rushed forward one by one.

Ye Yang's undead creatures came forward, and there were skeletons summoned.

Twelve skeletons, their bodies emitting light, were shooting wildly with guns. Under the power of illusion, dozens of skeleton illusions are released.

The shadow creature rushes forward and brings over the enemy creature, or is seriously injured or slightly injured and knocked unconscious.

Ye Yang reached out and touched the unconscious "dark elf".

I felt a strange force coming from my palm.

It is cold in the warmth, as if ice and heat are mixed. In the middle, some are warm currents formed by the intersection of cold and heat, and some are completely different air currents of cold and heat.

The muscles, bones and blood vessels on the hand were squeezed by strange forces, causing slight pain, and the body didn't feel good.

Observe your state. You can suck back up to 20 points by spending 10 points of mental power.

A "dark elf" can absorb 40 ~ 100 mental power and consume 20 ~ 50 mental power, but it takes a little time and consumes a lot.

Ye Yang calculated a little and came to a rather surprising conclusion... As long as the method is correct, he can convert undead creatures with almost zero consumption, and may even make a little profit.

"Draw their vitality to near exhaustion first, then hypnotize them and use the touch of the nether world. However, this must be controlled well. If you don't control it well and accidentally draw too much of their vitality, they may die and can't be transformed into undead creatures... You can use corpse resurrection and summon skeletons at most."

Ye Yang conducted several tests.

It was found that there was no way to achieve complete zero consumption. Because the more powerful creatures become undead creatures, the more spiritual power they consume.

Moreover, at least about one fifth of their vitality must be retained to ensure that their strength will not decline too much after they are transformed into undead creatures. Part of the vitality before death will be transformed into part of the strength of the dead after death.

Therefore, attention must be paid to this aspect.

However, this can greatly reduce Ye Yang's mental consumption.

As long as a steady stream of dark creatures are caught, it means a steady stream of undead creatures can be created. For each undead creature transformed, including the consumption of "hypnosis", you only need to pay 1.5 mental power at most, less than 2 points.

With Ye Yang's mental power of more than 400 points, he can continuously transform more than 200 undead creatures, so he needs to rest.

Assuming that the time required for hypnosis is converted to one every minute to 90 seconds, more than 40 can be converted in an hour.

Many times faster than before.

In only five or six hours, his men can have more than 200 undead elite.

Moreover, if ye Yang consumes too much spiritual power, he can directly drain the vitality of some dark creatures without transforming the dead.

If it is an ordinary dark creature, it consumes 10 to 15 mental power and can supplement 20 to 30 mental power. Most can reach about 30 points, and some can even reach more or even hundreds of points.

But even the most common undead can almost fill up the spiritual power by absorbing more than a dozen.

Therefore, the continuous transformation of undead creatures is not a problem.

The only restriction on speed is that magic hypnosis takes time. But this is to ensure their loyalty. Implant the most fearful impression into their hearts and make them fear ye Yang and Ji Yan... Yes, double insurance. Ye Yang is the most feared, followed by Ji Yan. If the two are superimposed, the effect is better.

They will be afraid of Ye Yang and Ji Yan. If they obey orders, they will not dare to hurt Ji Yan. Unless they get Ye Yang's orders, they can't fight Ye Yang because of Ji Yan's orders. This is the best way at present.

Ye Yang is cautious. What if those undead creatures encounter the power influence of other spiritual powers and are no longer afraid of Ye Yang? At that time, Ji Yan could come in handy. If others think Ji Yan is the master of these undead creatures and use spiritual powers to make undead creatures not afraid of Ji Yan and even attack Ji Yan in turn, Ye Yang can still restrain them.

That's why they fear two people at the same time.

In the future, they will be sent to Ji Yan as a bodyguard and Ye Yang as a bodyguard, which can really rest assured.

Monster by monster.

The drawback is that not much of the power absorbed by "life transformation" can be transformed into "upgrading energy".

So Ye Yang became picky.

Only dark creatures and monsters with certain strength can be transformed into their undead.

If your strength is a little poor, you can kill it directly.

I don't even have time to use "life transformation" to absorb their power. Instead, let shadow creatures kill them directly.

Ji Yan watched Ye Yang work all the way.

Anyway, it's not the most important secret, and there's no need to hide it from her.

After watching for a while, Ji Yan also asked for a shot.

She didn't rush to the front to kill all kinds of dark creatures and monsters, but she let Ye Yang transform the undead creatures into full gear. Including their living armor, plus the modern equipment supported by Ji Yan.

Their goal is to rush up and drag the injured dark creatures and monsters back, and then absorb their vitality with the Holy Grail.

Because after testing, these holy liquid and holy water transformed from vitality have no hidden dangers. Ji Yan can take them directly.

"As long as there is enough holy liquid and water, plus appropriate materials, I can also try to make physical strengthening potion, strength strengthening potion and spirit strengthening potion." Ji Yan said.

Ye Yang is very happy, but he is also a little worried.

I have absorbed the essence of the Holy Grail and improved it. It is estimated that the effect of the physical strengthening medicine on him will decline, and so will the mental strengthening medicine.

However, this is also expected. It is impossible for any kind of medicine to strengthen indefinitely. Otherwise, Ye Yang promised not to do anything else. He directly kept brushing and robbing the materials, and asked Ji Yan to make the materials into medicine. Isn't it easy for Ye Yang to brush all the attributes to 100 + or even hundreds?

There is nothing so cheap in the world.

"Make more," Ye Yang said.

After that, there was constant fighting.

I don't know how long in the past, there have been more than 400 undead creatures around Ye Yang. Each one on the pre apocalyptic earth is far beyond the strength of the top warrior level.

The only bad thing is that the figure and appearance are strange. In the pre apocalyptic environment, we can't let it out casually.

"If we bring this team to the pre apocalyptic environment, in this world, in any country with a peaceful environment, it will not be difficult for them to slaughter the armed forces of an entire city, or sneak into the army to uproot an army."

Ye Yang couldn't help ambition when he thought about it.

In this world, there are also terrible things such as nuclear weapons. If not restricted, the present world will become the end of the world at any time.

"Wouldn't it be great if I could have huge power in this world, destroy or lock all kinds of nuclear weapons secretly, and even set up a country or control several countries secretly? Many things can be done."

However, I'm afraid it's not enough to rely on yourself, even if you are strong.

Ye Yang is finally moved to get Ji Yan into this world. However, cross domain transmission is too pit, and he still hesitates.

"Go up to level 20 first."

The idea flashed in my heart, and I heard Ji Yan say, "there seems to be no monster."

"Well, even if we kill so many people, we should kill almost. Unless the underground space is huge and endless, there can't be so many creatures coming out." Ye Yang said.

In this world, even if it is weird, some basic rules still follow.

For example, creatures with mouths or mouthparts, especially those with abdomen and intestines, must eat.

The basic rules of the food chain should be observed.

To feed so many dark creatures and all kinds of monsters, the source of food must be indispensable.

Even if they can draw energy from the void or the earth to supplement their vitality, they can't not eat at all. Otherwise, the intestine would have degenerated. Even the mouthparts degenerate and can make sound with a cavity hole. But without variation, you must still need to eat.

How big is the underground space to provide them with enough food? If monsters are endless, how much food do you need?

This is not like a game. You can refresh monsters continuously without paying attention to eating and drinking Lazar.

"Take a break, let's move on." Ye Yang said.

Ji Yan was a little stunned, but she didn't object.

Ye Yang sent more than 20 undead creatures back to the rear camp and didn't explain anything to company commander Zhao and General Liu. They wanted to come or didn't want to come. Ye Yang didn't plan to pay attention to it now. However, when several undead creatures go back, they must let other undead creatures come and "change shifts".

Go back twenty-four, come back twenty-four. Of the twenty-four returned, eight were sent from here, and the other sixteen must be mobilized from the dead creatures stationed in the camp.

After a period of time, some will be sent back and some will come back.

In this way, we can ensure uninterrupted contact between this side and the camp side.

Moreover, we can find out what happens in the camp at the first time.

If Zhao Lianchang and General Liu want to do something to Ye Yang's men, such as bullying or fooling, it's clear here.

Even if they don't want to do anything irrational, it's enough to interrupt some of their thoughts by sending undead creatures back to change shifts.

To prevent them from acting unwisely, Ye Yang can avoid a lot of trouble - although he is not afraid of these two guys, it is always good to have less trouble.

After a period of rest here, Ye Yang has woken up and Ji Yan is still sleeping.

Ye Yang spent some mental energy to practice his skills and brush his skill proficiency. Sleep a little longer and wake up again. Ji Yan woke up with her.

"Let's go."

At Ye Yang's command, the undead driving in front stepped on the switch.

This bulletproof car is powered by electricity, gasoline, and a mixture of electricity and gasoline.

After modification, the car can not only be driven by gasoline and electricity at the same time, but also be moved by inserting an electric energy crystal core when necessary.

The undead creatures around had already come and stood in line.

When they had a rest before, they stood guard in turn. If they had nothing to do, they played cards or whispered about how to talk and play games with the bodies of the dead. Others watch movies and TV dramas nearby, which is not much different from when they were alive.

The captain in charge of guarding the dead came to report the situation. During this period, several dark creatures came to spy, but they were killed. One of them was killed by Ye Yang's shadow creature.

It is preliminarily estimated that there are many dark creatures, and they must be thinking about how to retaliate.

Ye Yang and his party, the whole team was on guard around and moved forward cautiously.

There are spies in front, dead scouts on the left and right sides, and even behind to prevent dark creatures from encircling from the rear.

However, all the way was quite calm, which was beyond the expectation of Ye Yang and Ji Yan.

After nearly fifteen kilometers, we saw light ahead.

Go on and find the corridor.

500 meter long tunnel.

Ye Yang stopped and asked the undead creatures to detect. The shadow creatures also drilled into the gap of the tunnel to observe whether there were traps in it.

Sure enough, we found some explosive things and were taken away by shadow creatures.

"Want to wait until we cross the tunnel and detonate? Bury us? Really have an idea, but it's a pity..."

Ye Yang waited and did not rush through the tunnel.

Soon, undead creatures will return.

"What? Outside the tunnel is the ground? There is a valley?"

Ye Yang quickly grabbed the cell phone handed over by the undead and looked at the video taken inside.

Ji Yan also came to have a look and said, "eh? There are many green plants in the valley, and they look familiar..."

"Look familiar?"

"Yes, most of them... Well, at least I know, many of them are plants on earth."

Ye Yang was surprised.

Opposite, is it a space with a very similar environment to the earth, or... Is it still the earth? The valley is still a corner of the earth?
