The mine was not dug deep. Zhou Han probably walked about ten feet in the mine and arrived at the end.

This is a stone chamber about two Zhangs in length, width and height. There are lighting facilities on the stone walls. The whole stone chamber looks very bright.

There is a stone table in the center of the stone room. Beside the stone table, an old man keeps writing something on the paper. Zhou Han came in, the old man was still engrossed in writing, did not notice Zhou Han.

This old man was Feng Zhicheng. After hearing about the production of source stone by the old national master, he immediately put down his task at hand and ignored the huge losses and came here immediately.

"Grandfather Feng..." Zhou Han called Feng Zhicheng in a low voice, and the latter immediately waved his hand to show Zhou Han not to speak.

Zhou Han saw this, it must be Feng Zhicheng should be writing very important things, now can't disturb, so Zhou Han stood quietly on one side.

There are many dense small holes on the stone chamber, which are the traces left by the gold eating insects. But now there is no shadow of the gold eating insects on the stone wall. It should be that the gold eating insects have eaten up the iron atoms on the stone wall and have gone deep into it.

Zhou Han stretched out a hand and stuck it on the stone wall. Then he said to the spirit offering, "sacrifice spirit, you can start to supplement your source power now."

The energy of sacrificing spirits is sent out from the stone wall, which will not be discovered by Feng Zhicheng. In fact, now Feng Zhicheng is concentrating on writing something. He doesn't even lift his head, nor can he see Zhou Han's movements.

"Good." After the sacrifice, Zhou Hanli even felt a strange energy in his mind passed through his palm to the stone wall. Zhou Han knew that this strange energy should be the soft white light of sacrificial spirits.

Soon, Zhou Han felt that a lot of things were being put into the space of sacrifice through his palm.

Zhou Han knows that this so-called thing is the source force.

This process takes more than one cup of tea.

"Sacrifice to the spirit, now your source power is two thousandths of that of your victory period." Zhou Han asked, last time Zhou Han absorbed the source of 800000 goldworms. This time, he added a cup of tea, so he should absorb more source power.

"One and a half ten thousand." Sacrifice to the spirit.

"What, only one and a half per ten thousand?" Zhou Han has no words to say. The source force absorbed last time and this time should be 2.5% of 10000. How can it be 1.5% per 10000?

"You think I don't need source power to build purgatory space. Do you think you don't need to consume my source power when you hone in purgatory space?" Sacrifice to the spirit.

"So it is." Zhou Han nodded his head. In this way, it makes sense.

However, Zhou Han soon found the problem, the source force seems to use too fast.

Zhou Han asked, "sacrifice spirit, did you use this source power too quickly, as if to build a purgatory space, and then I just honed it for a few days, and used up one in ten thousand?"

"Building purgatory space consumes most of the source power. When you hone in purgatory space, the source power is not consumed much. Don't worry, purgatory space has been constructed, the rest is mainly your training consumption, a supplement of one ten thousand source power, enough for you to hone the purgatory space for a month. " Sacrifice to the spirit.

"Well." Zhou Han was relieved. This source power can be replenished once a week, and he can use it up in a month. He doesn't have to worry about the source power for the time being.

Zhou Han Gang and the spirit of communication, then Feng Zhicheng also put down the pen, a long sigh of relief, looking at Zhou Han: "Zhou Han, how did you come?"

"Hehe, I just look around and see if I can help you?" The spirit worship has already added the source power. If Feng Zhicheng is not busy, then Zhou Han will go to the paradise where the family members of the Wuyun league can be resettled.

Zhou Han hasn't visited his relatives for such a long time. After entering the Fu clan, I'm afraid he has no time.

Therefore, in these two months, except for those important things to go out to deal with, if there is nothing particularly important, Zhou Han will basically practice in the paradise and accompany his relatives.

"Your brain is very smart. I happen to have a problem here. I need your help to refer to it. Come here." Feng Zhicheng greets Zhou Han with a smile.

Zhou Han walked past. It turned out that Feng Zhicheng was not writing on paper, but drawing drawings. This drawing looks a little complicated. Zhou Han didn't see what it was for a while.

"Zhou Han, this drawing is a kind of mechanism drawing, which can automatically lure and prey on Golden bugs without disturbing other golden bugs. But now, there is a problem: how should we let the golden bugs automatically touch this mechanism?" Feng Zhicheng said to Zhou Han.

"The mechanism that automatically traps and preys on Golden bugs?" Zhou Han was stunned. Although he still didn't understand the drawing, he was a little surprised.

Feng Zhicheng really has some goods. He can draw such drawings. You know, goldbugs are very dangerous. Once you blow up a nest, it's a disaster.

"Well, I used to be in the factory where source rocks are produced. The way they lure insects to touch the mechanism automatically is not suitable for the Universiade military alliance, so we have to think of another new way." Feng Zhicheng said."I don't know what was the way you lured the beetles in the source rock factory you stayed in early years?" Zhou Han is very strange. How can this way not be suitable for the Universiade Wu League.

"Goldbugs, as the name suggests, eat all metals, and the more precious the metal, the more they like it. In the factory where I stayed in the early years, people used extremely precious metals to lure and eat golden insects, such as the meteorite spirit for making weapons and the fire spirit for increasing the flexibility of weapons Feng Zhicheng said.

"So it is." Zhou Han was quite surprised.

The meteorite iron spirit, which is used to make weapons, must be valuable. Before Zhou Han, the body of the meteorite pointed gun was not very valuable. The main reason was that the tip was valuable. And its gun tip is only made of meteorite iron, not meteorite.

And the fire spirit, which can increase the flexibility of weapons, is certainly not inferior to the meteorite spirit. It may be even more valuable. This kind of luxurious seduction method is only suitable for those big powers with big money, but it is not suitable for the Universiade military alliance.

"Well, we have to find a way to make the beetle touch the mechanism automatically, and then save the cost. Otherwise, I'm afraid we'll have to buy those extremely precious metals as bait." Feng Zhicheng said, "although the cost is huge, but there is still a profit."

Zhou Han didn't know much about the source rock of production and the goldbug. No matter how clever he was, he couldn't come up with a solution now.

But Zhou Han had a sacrifice in his mind. Zhou Han immediately asked for advice on the sacrifice: "sacrifice to the spirit, do you have any way?"

"There are many ways." Sacrifice to the spirit.

"There are many ways?" Zhou Han was surprised, but he didn't expect that the sacrifice would be like this. You know, the golden insect can't blow up the nest.

"Nonsense, in ancient times, it was very popular to extract the source from the golden bugs. There were various ways for the major forces to catch the beetles. If we relied on the old man's method, it would be to think of a way on the bait. It's very simple. In fact, we don't need to prepare any precious metal, just use a few talisman." Sacrifice to the spirit.

"Talisman, what kind of talisman?" Zhou Han asked in a hurry.

"It's very simple. Goldworms perceive the outside world by their sense of smell and touch. Each adult beetle immediately looks for the opposite sex and then reproduces the next generation. Therefore, as long as the talisman can send out the mate message of female or male goldworms, then it will naturally attract the opposite sex goldworms Sacrifice to the spirit.

"What kind of talisman is this?" This method of offering sacrifices to the spirits is quite easy, but Zhou Han has not seen this talisman, so it is difficult to make it.

"Very simple, is the ordinary recording talisman." Sacrifice to the spirit.

"Ordinary recording talisman?" Recording talisman is the most common, but it doesn't even have a grade.

"Yes, use the recording talisman to record the information and play it in the mechanism." Sacrifice to the spirit.

"Lying trough, it's really simple enough." Zhou Han said in his heart.

However, looking at Feng Zhicheng's eyes, Zhou Han is a bit puzzled. How should he tell Feng Zhicheng.

After all, he didn't know anything about goldworms. When Feng Zhicheng asked, he immediately came up with a solution. This will certainly make Feng Zhicheng suspicious.

"Hehe, granddad Feng, this problem is really difficult, but I'll leave it to me. You can follow the mechanism. I promise to figure out the way before the mechanism is put into use." Zhou Han said with a smile. Anyway, the mechanism is still a drawing, and it can't start production for a while and a half. It's a kind of cover up for Zhou Han.

"Ha ha, if this problem is solved, all the forces producing source rocks will not be crazy." Feng Zhicheng also laughed and said to Zhou Han, "this problem is really hard enough. If you can't think of it, don't force it. You don't have to promise in front of me."

Obviously, Feng Zhicheng didn't believe Zhou Han could come up with a way. After all, there is no shortage of intelligent people like Zhou Han in the factory where source rocks are produced.

"Grandfather Feng, what are the next procedures, and then the source stone can start production?"

"There are only two of them. The first is to get the equipment for the production of source rocks. The second is the craftsman who produces the source stone. " Feng Zhicheng said, "these two things are very difficult to do. The equipment for producing source stones is strictly controlled, and there is generally no power to make these things. After all, once someone needs it, others will doubt whether it can be used to produce source rocks. If others think like this, they will surely think whether they have a large number of resources to make source rocks in their hands. Maybe they will have evil intentions. There are also the craftsmen who produce the source stone. These craftsmen are not ordinary workers. They are all masters of Fuwen with very strong mental strength. They are generally not short of money, so it is difficult to get them

Zhou Han is also listening to frown, these two are really not easy, but since Feng Zhicheng has come, and has started to work, he should have a way.
