When I woke up, it was rare to dream again, dreaming of a very magical technology, completely different from technology but similar to technology, that is a technology that does not need to borrow special materials, and can communicate energy with divine thoughts, leaving permanent imprint runes on weapons and equipment.

It's just very strange that what I dreamed about this time is completely different from the technology I dreamed of before, and I dreamed of it before, and after a certain technology, I will recall some application experiences, and the technology I dreamed of this time has no application cases at all.

I wonder if this technology is feasible in the end, if it is said that some very special materials are used to build some formations, it is possible that I have remembered many of the previous technologies, but I can't get a room temperature superconducting material with superior performance, so I can't test it, but this time I directly used the divine mind to restrain the energy to replace the material.

I was too curious and decided to try the real thing, and I didn't lose anything if I failed. Chihe Town is now considered the territory of devils, and of course it is not good to do experiments here, so I quickly packed up and went to Dingyuan County, which is dozens of kilometers away, and Dingyuan is still under the control of the national army.

I found an abandoned and dilapidated house in the suburbs and lived in it, on the one hand, I studied the pure energy rune array, and on the other hand, I was waiting for the Japanese army to assemble and attack their ammunition depot or headquarters and other important targets before the war, and then go back.

If you want to directly outline the formation with energy, of course, you have to find those special energies first, and only those mysterious energies that are completely different from this world can be able to gather and not disperse to form an energy formation.

Restore some memories that call that special energy dark energy or chaotic energy, under normal circumstances, scientific equipment cannot detect the existence of dark energy, because it and the known electromagnetic radiation is completely unreflected, and if it is not reflected, it will naturally be impossible to detect and observe. The only means that can discover these energies, as far as Li Yunfei knows, only the spiritual perception of living beings can discover those special energies.

Slightly closed his eyes and concentrated on spreading his senses, looking for the legendary dark (chaotic) energy, through the feelings experienced in the dream, he finally found a trace of dark energy that was almost indelible in countless energy fluctuations.

To be honest, if you hadn't experienced the dark energy of communication in your dreams, it would have been impossible to find these energy that were so weak that you could ignore it. It took more than three hours to simply perceive and discover dark energy, so this technique was countless times more difficult than expected.

(In fact, this world is very stable and the world where Li Yunfei went last time was full of holes and dark energy can be seen everywhere, of course, it is completely different, if it is in that world, with Li Yunfei's spiritual power, the formation can be built in minutes)

After resting for a period of time to recover the mental power, concentrate again, to perceive those dark energy, with the last experience, the time is slightly shortened, and after discovering the dark energy, I will rest again to replenish my mental power, and then perceive it again.

The dark energy is too little, so I have to train like this, otherwise I can't build a formation even if I borrow it, and I can only continue to learn and perceive more dark energy.

I stayed in a small broken house for three days, and I felt dizzy and uncomfortable all day long, and finally gave myself a half-day vacation, high-intensity dark energy perception training, and my brain was about to short circuit.

……

Walking on the streets of Dingyuan County, which seems to be a little deserted, the war is coming, the real rich families have already begun to relocate, and the really poor people who can't eat have also begun to flee, and only those who are not rich and have a little bit of property are really reluctant to risk staying in this family business.

A large number of devil soldiers were assembled in the direction of Chihe Town and did not rush to attack Dingyuan, because the bridge had not been repaired, and the heavy weapons could not be transported for a while.

It should take three or four days to repair the bridge, Li Yunfei has already thought about it, and when the bridge is repaired, he will blow it up again, and even destroy some of the devil's heavy weapons as much as possible, so as to eliminate the devil's advantage, and then he can also retire and figure out the energy array well, and strive to one day it can really be used in weapons.

Although this kind of technology, which is supported by strong spiritual power, cannot be popularized and used on a large scale, nor is it possible to mass-produce mysterious weapons and equipment, it is still possible to prepare a few of his dozen subordinates.

Chop wood without mistake and sharpen the knife, and strive to make a set of armor and two weapons for everyone, and then ......

When I was thinking about YY, I suddenly saw a somewhat familiar figure on the street, which was the woman who suspected that there was a problem with her identity last time. The woman's behavior was indeed a bit strange, as if she was afraid of being discovered, and looked around from time to time, and then continued walking, and finally entered a teahouse.

Originally, I didn't want to be nosy, but it didn't seem to be anything, so I followed, with a magical perception assistance, and easily avoided people.

"Xiao Tang, what's so urgent?" An old man in the secret room asked a little strangely.

"When I was operating a few days ago, I discovered that the mysterious person codenamed 'Dragon' did exist, and his ability may be higher than expected......

"Did you see that? Where is he now? ”

"Yes, I saw it, but there were many people from the national army at that time, and I was also a member of the national army, so I deliberately forced him back so as not to be drawn into the camp by the Kuomintang...... Unfortunately, when I went back to look for him again, I couldn't find him. ”

"Your identity isn't revealed, is it?"

"Not yet!"

The two were talking in the secret room, but Li Yunfei, who was lurking outside, heard it clearly, and it was really a little surprising that this woman still had such an identity.

In the end, whether to consider showing up, this is a serious question, the plan is to wait for those subordinates on the mountain to complete their training, they will go to the three northeastern provinces to do a big job, if there is Yan'an to cooperate with the action, there is definitely a chance to completely annihilate and annihilate Unit 731, and even have a chance to annihilate hundreds of thousands of Kwantung Army.

If the plan goes well, it can even take back the three eastern provinces, which have a fairly large industrial base, where the devils have worked hard for seven or eight years, and the industrial base is quite strong, with steel production of more than one million tons.

This output is just a drop in the bucket for Huaguo in later generations, but now Huaguo's national steel output is only more than 100,000 tons, so it can really grab that place, if it can still be held, it will be a super invincible pill for Huaguo, which has been extremely weak for many years. As for how to grab and how to guard, of course, this will be slowly figured out in the future......

"Xiao Tang, you try to get in touch with that mysterious person as much as possible, and be sure to explain to him that there are too many factions in the Chongqing government and they are not reliable, if you have the opportunity, guide him to Yan'an as much as possible, and if you can complete this task, you can give up all other tasks."

“…… I seem to have offended him last time! Xiao Tang said with some hesitation.

"Judging from that person's style of acting, he is not so stingy, if he is really a stingy person, Chongqing robbed him of his credit, and he would have gone to Chongqing to make trouble instead of appearing in Chihe Town to help, and even the success of Nanjing City a few days ago was also the credit of that person!"

"That's okay, if there is still a chance to see it, I will do my best, but that person Shenlong can't see the head and the tail......"

"Shouldn't I thank you for the compliment?" Li Yunfei pushed the door directly in, but decided to contact these two people, preparing to go north after more than half a year to carry out the plan of drawing salaries from the bottom of the kettle, if the devil's power in China is not supported by the industrial base of the three eastern provinces, it will be weakened by at least a small half.

The old man was quite calm, just glanced at Xiao Tang, and after getting a sure look, he stood up directly and greeted him.

"You're welcome, old man, I just want to use your intelligence system to say something to Yan'an."

"What's the matter, sir, please tell me!"

"After October this year, I will go to the three northeastern provinces to carry out a salary draw action against the devils, and if I can hope that Yan'an will cooperate."

"Why is it after October, when the weather in the three eastern provinces is already quite cold?"

"It is precisely because of the cold that I have the opportunity to destroy their garrison......" Li Yunfei explained, in fact, there is another reason, that is, the weather is cold, and it is unlikely that the devil's base camp will increase troops to the northeast, so if there is a chance to annihilate the Kwantung Army, it is very likely to occupy the three eastern provinces for half a year, and in such a long time, you can do a lot of things. Of course, this plan is a bit of a braggart, so I didn't say it directly.
