Wu Sheng needed a confidentiality measure, which not only required that others could eliminate counterfeiting, but not too complicated.

In the end, Wu Sheng had to hand over the Yinshi Tree to others to make, and he had only one person himself. Even if he made Yinshi Tree for his whole life, it would be difficult to meet the market demand of Yinshi Tree.

Fortunately, he has some knowledge support during the super-dimensional period.

After careful search of the underground relics information obtained by Daina, Wu Sheng chose a special encryption method.

This method can transform the external manifestation of any information, so that others cannot see the real original information at all. Wu Sheng does not know the specific principle, but for him, it is enough.

In addition, this encryption method contains an authorization activation system.

The encrypted information can be set to a "lock". The cryptor can create a "key". Only the "lock" authorized by the "key" can be opened and the information inside it can truly work.

"Key" can also be made in grades, advanced "Key" can activate low-level "Key", and so on.

Wu Sheng changed this encryption method to "Wu Suo". It is not difficult to make Wu Suo's "key", and a key can set the authorization quantity so that he can control the activation quantity.

In this way, Wu Sheng can completely teach his partner how to make everything including Yinshi Tree, "Wu Suo" and low-level "key".

As long as the other party finds someone (ghost) to make the Yinshi Tree (naturally includes Wu Suo) and low-level keys of different levels according to the method he teaches, and then activate it with the main key given by Wu Sheng, you can get the available Yinshi Tree.

Wu Sheng himself simply made some high-end keys, which could completely control the sales of Yinshi Trees and gain benefits from them without being deceived.

In this way, after another month of repeated improvements and improvements, Yinshi Tree Technology was officially completed!

At the beginning of the fourth month when the Lord reopened the [Dead Soul Realm], Wu Sheng rarely had a rest in Wu's mansion and did not leave here to go to his underground laboratory.

He summoned the butler Zhu Hao and sent him to Zhou's mansion to invite Miss Zhou to come here to discuss things.

After careful consideration, Wu Sheng finally decided to hand over the Yinshi Tree technology to Zhou Ping and let her cooperate with her to sell this new thing that is likely to change the [Life and Death Realm].

As one of the Star Lords of Shangmeng, Zhou Ping's main business is to make alchemy and refine medicine, but it does not mean that she does not involve other industries. It is just that other industries under Zhou Ping's leadership cannot keep up with her scale in the alchemy and pharmaceutical field.

Zhou Ping's identity is there. Among the people Wu Sheng knew, she was the most suitable and capable of quickly promoting and spreading the Yinshi Tree.

Zhou Ping has been in Nanlin City recently, which is the headquarters of [Fuxi Hall]. She handles matters in various branches here, and is always paying attention to the impact of ghost tide on various cities.

As soon as he received Wu Sheng's invitation, Zhou Ping quickly put down her work and dressed up.

As the situation outside the city becomes increasingly severe, Nanlin City has been locked down, and all ghosts who do not have their own residence or work in the city will not be issued long-term residence documents.

Only after verification by outsiders, some temporary residence certificates will be issued. Depending on the reason for arrival, the allowable residence time is also different, and it is generally not too long.

When he arrived at Wu's mansion, Zhou Ping saw Wu Sheng waiting for her in the courtyard.

Wu Sheng was still dressed as a cultivator, while Zhou Ping also had the same style as a men's literati last time, but she changed her clothes and decorations.

"Young Master Wu is in a good mood. I guess there must be a happy event in the near future."

"Ms. Zhou is indeed very keen. Wu has indeed gained something recently. I asked Miss Zhou to come over today because it is related to the recent gains."

After saying that, Wu Sheng waved his hand to signal Zhou Ping to follow him.

He took Zhou Ping away from the eastern residential area of ​​Wu Mansion and came to the central main park area.

The main garden is still full of flowers and ancient trees are uneven, but among these uneven ancient trees, there is a ghost locust tree that Wu Sheng specially found someone to transplant.

Generally speaking, no one from the wealthy family will transplant ghost locust trees in the courtyard garden. Because this kind of tree is too ordinary, the mountains and fields are everywhere outside the city, and the effect of gathering yin energy is not very useful to the wealthy family.

In the words of [Source World], wealthy people plant such trees in the courtyard and lose their grades.

Therefore, although this ghost locust is not big, it is very eye-catching among the various rare flowers, plants and trees in the Master Garden of Wufu.

Zhou Ping saw this ghost locust tree that was very conspicuous in the entire main garden at a glance.

Her face was a little strange, thinking that the last time she came, there shouldn't be this ghost locust in the main garden. Unexpectedly, Mr. Wu was really weird. She liked to plant this eye-catching plant in a good garden, which instantly lowered the style of the Wu Mansion's main garden.

But she didn't say anything. It was their freedom to have any other people's preferences. Besides, Mr. Wu is a real Bai Wuchang. Even though her taste is a bit strange, she didn't want to cause the other party to be unhappy because of her different personal opinions, so she simply turned a blind eye to this ghost locust.

Unexpectedly, Wu Sheng took her directly to Guihuai. This time, Zhou Ping could not ignore her.

When he arrived in front of Guihuai, Wu Sheng pointed to his torso and said to Zhou Ping: "Today Wu asked Miss Zhou to come here for it."

Zhou Ping looked a little embarrassed, and she didn't know what to say, so she could only squeeze out some words: "Mr. Wu's taste is indeed different. This ghost locust is tall and lush, simple and natural..."

When Wu Sheng heard what Zhou Ping said, he realized that the other party was wrong about his meaning and interrupted directly:

"Ms. Zhou understood what Wu meant wrongly. Today I did not bring Ms. Zhou to taste the ghost locust that can be seen everywhere in the [Soul Realm]. Although Wu himself likes this ordinary and tough plant, he also knows that the Wu Mansion Master Garden is not suitable for transplanting such too ordinary trees."

After listening to Wu Sheng's words, even with Zhou Ping's shopping mall experience, she felt even more embarrassed.

Unexpectedly, she, who has always been smart, will make cognitive mistakes, and she flattered her horse's legs.

Wu Sheng noticed Zhou Ping's embarrassment, turned to the topic and began to talk about the serious matter:

"I like to study some strange things. I have gained something in the Yang world some time ago. Recently, I have been in seclusion and combined with what I know and learn, and have made some transformations on the ghost locust tree that is very common in the soul world."

"This ghost locust tree is the result of Wu's recent exploration. When we first met, Ms. Zhou once said that she was interested in what Wu developed, so Wu had just improved it and made this sample, so she invited Ms. Zhou to come over."
