Chu Yun explained his needs to Qin Lang in detail, and after listening, Qin Lang said that he would try his best to make this kind of instrument, and said that if there was a way to use spiritual power, it might be helpful to make this instrument.

This reminded Chu Yun that in the cultivation world, some refiners used spiritual power to make some magic weapons, and perhaps these scientists on the earth might use spiritual power to create some unexpected things.

Thinking of this, Chu Yun told Qin Lang some of the basic methods of using spiritual power, the so-called methods of use are some basic cultivation methods, but Chu Yun did not limit these methods to people, but included all things.

Like a formation mage, you can use spiritual power to arrange formations, like an alchemist can use spiritual power to refine medicine, like a refiner can use spiritual power to refine weapons, etc., in fact, using spiritual power to cultivate is the most basic way to use spiritual power.

After listening to Chu Yun's explanation, Qin Lang said that he had benefited a lot, and solved the bottleneck that he had been unable to figure out before, and finally said that he could make the kind of lightning adjustment instrument that Chu Yun needed within a week.

After sending off No. 8 and Qin Lang, Chu Yun set out to arrange a small spirit gathering array in the backyard of the random building, of course, there will also be a psychedelic array for defense around, and it took a whole day to finally arrange a simple formation in the medicine field in the backyard, and the token of the formation Chu Yun did not hand it over to Sun Zijian, because Chu Lan said that she was going to come to the random building in the capital to help.

Chu Yun planned to wait for Chu Lan to come and hand over the token of the formation to her, it was not that Chu Yun did not trust Sun Zijian, but he felt that Sun Zijian had an impetuous personality and did not have a city government, so he was not reliable, and Chu Yun was really not at ease when he handed over the token to him.

The reason why Chu Lan wanted to come to the capital seemed to have something to tell Chu Yun in person, and the specific matter could only be known after Chu Lan came to the capital.

The next day, the old man of the Chu family who passed away held a funeral on this day, Chu Yun did not show up, and the Chu family did not mention the matter of letting Chu Yun participate, Chu Lan arrived in the capital in the evening, and went to the old man's grave to burn incense.

That night, Chu Lan and Chu Yun were alone in the study on the second floor, and Chu Yun knew that Chu Lan was going to tell him what he could only say in person.

"Big brother, this incident I told you may hit you, but I feel sorry for you if I don't tell you all the time, I think you should live more clearly, so I decided to tell you, do you know your background?"

Chu Lan carefully told Chu Yun everything she wanted to say throughout the whole process, it was about Chu Yun's life experience, it turned out that Chu Yun was not the Chu family, not the son of his father Chu Zongren, and not Chu Lan's eldest brother.

According to Chu Lan, when she found out that someone in the Chu family returned Chu Yun, she began to disguise herself, pretending to show disgust for Chu Yun, and in order to prevent anyone from being suspicious, she no longer paid Chu Yun phone bills from then on, that is, from that time on, he found that a conversation between the second master of the Chu family and the head of the Chu family was accidentally overheard by her.

It turned out that Chu Yun was framed and then kicked out of the house was planned by the second master of the Chu family and the head of the family, in order to sever the inheritance relationship with Chu Yun, because according to the generation, Chu Yun is the eldest son of the Chu family, but it is because Chu Yun's background is not the Chu family, so they will try their best to drive Chu Yun out of the Chu family.

The head of the Chu family originally just wanted to cut off relations with Chu Yun, but the second master of the Chu family was afraid that Chu Yun would make a comeback, so he made up his mind to cut the grass and eradicate the roots, so there was a series of things that assassinated Chu Yun.

As for Chu Yun's specific background, Chu Lan didn't know, and her decision to stay in the capital this time was to find out about this matter, although she and Chu Yun were not related by blood, their relationship was like that of brother and sister.

In the end, Chu Yun said that if Chu Lan and Chu Xinghai wanted to return to the Chu family, he would help them, and even help them become the head of the Chu family, but Chu Lan said that they only wanted to follow Chu Yun and didn't want to have anything to do with the Chu family anymore.

And for the twists and turns of his life experience, Chu Yun actually didn't care, he was not that Chu Yun himself, he was Chu Yun in the cultivation world, so he didn't want to investigate the so-called life experience, and Chu Lan insisted on investigating it, so let her investigate, Chu Yun also told her, safety first, it doesn't matter if you check it or not.

On the third day, Qin Lang came to the random building to find Chu Yun, saying that he had already paid attention to it, and when he first saw Qin Lang, Chu Yun almost didn't recognize the minister of this mysterious department, only to see that his two dark circles were dark and big, and his hair was messy, and he looked like he had stayed up all night.

Sure enough, according to Qin Lang, he has been studying in the laboratory since he left that day, and finally let him study it this morning, and he has done an experiment, successfully captured a piece of lightning, and through the adjustment of the instrument, the size of the current can be changed at will, and the maximum power can be as powerful as lightning.

Chu Yun looked at the instrument excitedly, this is a device similar to an umbrella, it is opened when it is used, there is a lightning guide device on the tip of the umbrella, and the lightning will be stored on the umbrella handle after it is drawn, and there is a button and a socket on the head of the umbrella handle, the button is to adjust the current size, and the socket is used for current output.

Qin Lang said that they are working overtime to improve all the instruments, and this time they have added the use of spiritual power, so that the scientific and technological achievements they research have advanced by leaps and bounds, at least fifty years ahead of other countries, but they also have an imminent problem now, that is, the lack of spiritual power.

The aura in this world is extremely scarce, which is also the reason why Chu Yun chose to cultivate thunder and lightning at the beginning, although he accidentally got the space stone later, but the aura in the space stone was not created out of thin air, and since the arrangement of the Five Elements Reversal Great Array, some aura was slowly produced.

But the aura is still limited, if you want to use it for cultivators' cultivation, the entry is okay, and if you want to cultivate more deeply, it is not enough, but Qin Lang's spiritual power required for their research is very limited, and they have made very fine calculations, and every trace of spiritual power can be used to the maximum.

Therefore, Chu Yun finally promised Qin Lang to help them solve the problem of the source of spiritual power, but he needed to know the results of their research, and if there was anything he needed, he could buy it at equal value.

Qin Lang also arrogantly said that if there is a stable source of spiritual power, they can give away a product developed for free, and it is every piece, as for the purchase, the decision is the cost price, because spiritual power itself is the treasure of prices, and their cost will also be calculated into the spiritual power.

They didn't have much interest in this, for the products they studied, Chu Yun only thought that they were external forces, and spiritual power could only exert its greatest effect when it was used for itself.

But at the moment, this thunder and lightning regulating device is still very good, and after sending Qin Lang away, Chu Yun can't wait to try it.
