Qin Lang named this thunder and lightning adjustment device the electric umbrella, and then everyone slowly called it an electric fan, and later in order to distinguish the difference between the electric umbrella and the electric fan, everyone called it the thunder umbrella.

According to Qin Lang, if this technology is further improved, the problem of the use of electricity in Huaguo will be completely solved, and the electricity of nature will be enough, not to mention that humans can also make lightning.

Chu Yun took the thunder umbrella and played curiously in the study, and then adjusted it to the power required for cultivation now, and the thunder umbrella showed that if it was output at this power size, it could support 36 hours, which was enough.

Chu Yun told Chu Lan and Sun Zijian that he was going out for two days, and then Chu Yun drove to a wilderness on the outskirts of the capital, took out a thunder umbrella, and then put his hand into it, and the dazzling electricity flowed from Chu Yun's fingers to his whole body, and then converged into the dantian.

The process of cultivation was painfully weeping, like thousands of ants biting in the cracks of bones and flesh, but he also enjoyed this feeling very much, because this feeling was also the feeling of becoming stronger.

After listening to a night of cultivation, Chu Yun's realm was already on the verge of breaking through, but his current physical fitness was still a little unable to keep up, so he could only transfer a part of the spiritual energy and some medicinal materials from the space stone to supplement his qi, and Chu Yun even extracted a part of the divine water from the Five Elements Reversal Great Array.

The effect of the divine water is huge, after drinking that small cup of divine water, Chu Yun touched the opportunity to break through, and then continued to discharge the cultivation, and finally the next day when the sun was slightly white, he finally successfully advanced to the third layer of martial arts, from the flesh refining realm to the bone refining realm.

Just as he entered the Bone Refining Realm, Chu Yun suddenly felt a movement below, so he used his mana to make the bottom grow again, and finally Chu Yun could pull out the plastic tube and become a healthy man again.

There was another thing that surprised Chu Yun, it was an unexpected gain, after he recovered his health below, he found that his Heavenly Eye had also been promoted, and he found that his Heavenly Eye could actually see through.

In the cultivation realm, perspective is an insignificant low-level spell, but there is a restriction, that is, those with low cultivation cannot see through higher than their own cultivation, but Chu Yun found that his heavenly eye can actually see through anyone, because he has already seen that there is a white snake that has cultivated for thousands of years hidden in the ground where he is sitting cross.

Chu Yun could clearly see that the white snake's inner dan had already shown a dark golden color, which was a symbol of a thousand years of cultivation, that is, the inner dan was yellow, like this snake should have just been a thousand years ago.

The white snake seemed to have a sense of Chu Yun's peeping, but it was incredulous, it now had spiritual intelligence, and it couldn't understand why a human teenager could actually see a white snake hidden three or four meters underground.

The White Snake probably felt that there was no need to hide any longer, so he actually broke out of the ground at Chu Yun. Chu Yun was already vigilant, and at the moment when the white snake moved, Chu Yun locked the seven-inch position of the white snake, and the reason why the seven-inch position was his lifeblood was that the seven-inch position hid the snake's inner dan, and the inner pill was the snake's life.

Chu Yun's palm was in the shape of an eagle's claw, and he grabbed it with one claw, and after dodging the white snake's bloody mouth, he held a dark yellow bead in his hand, the size of a goose egg.

And the white snake, after that pounce, lay on the ground and writhed and wried, and after a while, there was no movement, Chu Yun put the body of the white snake into the space stone, this is a great tonic medicinal material, and even if it is not a medicinal material, it is good to eat it as a meat when you go out in the future, who makes the space stone have a preservation function, and under the nourishment of spiritual power, it will only become fresher and fresher.

As for the Inner Dan, Chu Yun took it directly orally, then meditated cross-legged pranayama, and continued to use the remaining electricity and the medicinal effect of the snake pill to cultivate, this refining was a week over, and Chu Yun also successfully reached the peak of the third-level cultivation of a martial artist.

Returning to the random building again, Chu Yun touched his nose awkwardly after seeing Chu Lan, he now has the perspective function upgraded to Tianyan, and now he can't control it well, the first thing he looks at when he looks at people is perspective, just like seeing Chu Lan now, only the incomparable embarrassment in his heart remains.

Chu Lan was also very puzzled when she saw Chu Yun's strange expression, but because she had something important to find Chu Yun, she didn't explore it too much.

It turned out that in the more than a week that Chu Yun had been missing, Qin Lang would come to Chu Yun almost every day, because Chu Yun had promised to solve the problem of the source of spiritual power for him, but he had never found any trace of Chu Yun, but Chu Yun had just heard Qin Lan's voice coming from outside.

"Is Mr. Chu back?"

Chu Lan went out to greet him and said that Mr. had come back and was in the study on the second floor, so Qin Lang ran to the second floor and pushed open Chu Yun's door.

As soon as Qin Lang entered the door, he couldn't suppress his excitement and said that the results of his research in the past two days, such as the mechanical battle armor of man-machine integration, through the control of spiritual power, people and consciousness can already be connected with machinery, and a single thought can control the actions of machinery, of course, this is only the most basic action, and if you want to be able to participate in the battle, you still need a lot of experiments.

Another example is the nanobots they have been researching before, and now they can control nanobots with spiritual power, and if the follow-up research results are made, one person can control a nanobot army.

Of course, in addition to the military and medical, the use of spiritual power has solved most of the terminal diseases, Qin Lang said that he could cooperate with the random building, they are responsible for the research and development and production of drugs, and the random building is the only sales unit, in this regard, Chu Yun said that he would let him discuss with Zhao Ting and others, he just asked about this.

Qin Lang said a lot of research results, but these achievements are only in the initial stage, and saying a lot of them is equivalent to asking Chu Yun only one question, then these studies need further support from spiritual power, and there is hope with spiritual power.

After Qin Lang finished speaking, Chu Yun introduced the source of spiritual power to him, Qin Lang could send someone to come to the building regularly to get some spiritual water at will, these were all produced by the medicine garden, of course, Qin Lang needed to ask Chu Lan for spiritual water, because Chu Lan held the key to the medicine garden.

No. 8 also came to the random building at this time, he called Chu Yun two days ago and never got through, because Chu Yun was in retreat at that time, No. 8 came here mainly because of the Dong family, he investigated and found out that the Dong family actually went to an island country next door to Huaguo, and it seems that they have an ulterior secret with this island country.

In the past two days, the 8th has gone to the island country to explore, and the Dong family really appeared on the island, but they can't investigate what they are doing on the island, and it is speculated that some secret organizations in the island country have cut off the clues.
