After various tests, I found one thing... His ghost fog and bone spear can not only absorb the energy of one energy crystal nucleus, but also absorb the power of multiple energy crystal nuclei at the same time.

If the "ghost fog" absorbs the crystal nuclei of "darkness", "life" and "death" at the same time, it will become cold. When tested with a thermometer, the temperature does not change, but it will feel very cold when contacted with human skin, which seems to inhibit the activity of human Qi and blood.

This "ghost fog" mixed with three different energies actually has a "great tonic" effect on several ghosts. It can absorb the energy inside and make them stronger.

It is preliminarily estimated that the ghost fog created by Ye Yang can increase their spiritual power by how much spiritual power Ye Yang consumes.

However, these spiritual forces... Are one-off. Accumulated in their bodies, they will be consumed and dissipated slowly. If you use these mental forces to "mind control things", you can move some very light things, but it will quickly consume the power of the "dark cold fog" accumulated in your body.

Similarly, if you accumulate strength in your body, you can stay away from the ashes a kilometer away, but if you exceed a kilometer away, you will accelerate the consumption of strength. If you don't get back in time, you will quickly become weak and even hang up... Ye Yang mercilessly tested one of the ghosts to make sure that the other party didn't really hang up, but instantly transmitted it back to the ashes, Get in and sleep.

In addition, when these ghosts supplement and consume their power after exhausting their power, the strength of the noumenon will be improved. Even if the power of the dark ghost fog supplemented by Ye Yang is used, it is the same.

"In other words, this way can make them stronger slowly? You can train them."

Ye Yang decided to strengthen these ghosts to see how fast their strength increased. There are few other requirements, as long as they can explore intelligence several kilometers away from the ashes.

Of course, they are usually put into the space ring.

Although they are still very weak and do not pose any threat to Ye Yang, what will happen if they are strong enough to a certain extent? I have to.

"If there are some silly ghosts, they will wash their brains and lose their sense of loyalty at the beginning, which is much easier to control than these old ghosts."

After the test, it was found that the dark ghost fog combined with the power of the energy crystal core to cover their ashes can also enhance their strength and better effect.

As for further testing, it had little effect.

"There seem to be few ghosts in this country. Do you know where there are many ghosts?" Ye Yang asked.

Salina said, "why don't you go to the hospital and cemetery?"

Ye Yang went to the hospital wearing high imitation real human skin face tools and found some ghosts... Well, they are not real ghosts. They should be called "lost souls". They were drilled from people who had just died. On average, more than ten or twenty people died. They have a soul. They can't communicate. Some of them are stupid and float outside the hospital automatically, It dissipated when the wind blew.

Some are hidden in the body and can't float out.

"It's useless. There's almost no IQ."

Instead, I saw a female ghost on the roadside. It is said that she was killed and can communicate, but her face is full of hate. She will only roar madly, and the psychic can hear its voice. Not much IQ.

"Is it because the strong obsession before death condensed into a ghost? This is not a soul, but a group of obsession?"

It's just that this group's obsession is too weak.

In the cemetery group, you can see several ghosts, and Ye Yang caught them directly.

"Next, do further experiments."

Forcibly read the memory fragments of a ghost through the release of divine thoughts and the communication of the language of the dead.

Ye Yang was pleasantly surprised to find that his guess had become a reality - he could directly read the memory and copy it into his brain.

However, only a small number of memory fragments can be copied, allowing Ye Yang to master more than 1000 foreign language words and some grammar rules in just a few minutes.

In the hands of a group of ghosts, only two can copy their memories. Once they are copied, they become stupid, as if they have been "cut" off part of their thinking ability.

"It's inefficient, but... If there are enough ghosts, it can really save a lot of learning time. The key is to find suitable ghosts. And... The maximum mental power has been increased by 0.2?"

On average, one ghost can increase the upper limit of mental power by 0.1. 10 ghosts are 1 point, and 100 ghosts are increased by 10 points, which is equivalent to increasing 1 point's intelligence attribute.

"If you can find a lot of ghosts..."

After pondering for a while, Ye Yang felt that it was necessary to go to the war-torn country.

At present, there are more than a dozen war-torn countries in the world, but only a few are most concerned internationally. Even if a nuclear bomb is dropped, it will only be dropped on those countries, and other war-torn countries will not encounter the danger of "nuclear peace". So it's worth going.

"If the obsession before death is strong, the soul can be separated after death. The probability of ghosts in war-torn areas should be relatively large."

All the way to the slaughterhouse.

There are also some prison felons who don't need to wait for shooting. Ye Yang helped them solve it.

During this period, he also caught two newborn souls and directly forcibly read the memory fragments. Increased the mental power limit by 0.2.

Upgrade energy and gradually accumulate. It's just

The upgrade energy required to upgrade from lv11 to lv12 is 20000, which is a little too much.

"It is said that in a war-torn country, there are several cities, and almost all the people are frightened. If these cities are slaughtered, let alone lv12 and lv13, can they be promoted?"

As long as it's not domestic, as long as it doesn't expose its identity and has a good conscience, Ye Yang doesn't mind playing a big one.

"It's decided... Hagoda... Go there, you can upgrade to lv12, and then choose 'touch of the dead' to try to transform some living people into undead creatures for experiments."

Ye Yang still has several experimental plans in mind, but he needs materials.

So I didn't waste much time and quickly arrived at hagoda.

A city with a population of about 300000.

More people than the holy city in the last ages.

More than one-third of the people in this city, whether men, women, young or old, are terrorists, terrorists, Fen Zi, or are providing various cooperation and services for terrorists, terrorists, Fen Zi, or can be transformed into terrorists at any time.

Ye Yang just made some gunshots in the city, triggered some explosions, attracted a large group of armed people and killed them directly.

It was night.

The sky was shrouded in thick fog.

The power supply of the city has been completely cut off, and many places can only use standby power supply and generators.

It was dark all around.

After the gunfire and explosion came out, a large group of armed men came. After Ye Yang controlled the shadow creatures to wipe out a group of people, he summoned the skeleton and controlled the skeleton's armed attack. Or revive one or two corpses and let them join the attack.

The terrible situation here scared many armed men silly. But he was also shot directly. The ghost brought by Ye Yang also monitors the surroundings. Anyone who uses a camera, mobile phone or the like to shoot will be notified, and then kill them and destroy the shooting instruments.

"Even in this world, there are many people who can make me slaughter without guilt." Ye Yang stared at the system menu and watched the upgrade energy rise.

In the city, all the safe people hid and dared not move, but the fierce armed men poured in and were killed by Ye Yang's shadow creatures and skeletons.

The proficiency of "summon shadow", "summon skeleton" and "resurrect corpse" has been continuously improved. Summoning skeletons can be upgraded long ago. Ye Yang is still holding it. Don't worry. Choosing the direction of ascension too early may not be a good thing.

So, just a few hours.

The upgrade energy is enough. It can be upgraded to lv12.

"Next, upgrade and point out the touch of the nether world..."
