At this time, Chen Yuan completely understood what the dean's idea was, and the skill of making human skin masks by himself was a skill that the Nine Heavens Domain did not have, although this craft Chen Yuan would have to take it out and contribute to the Daoist Academy sooner or later, but when to take it out, and what to exchange for something and what conditions to put forward as a bargaining chip, Chen Yuan himself was in charge. This technology is of great benefit to the development of the Taoist Academy, especially the Military Palace, and the Taoist Academy must be obtained, so the conditions can be recognized by Chen Yuan, and the initiative is in the hands of Chen Yuan.

And the dean's hand is very beautiful, he did think about Chen Yuan very carefully, but the advice he gave was impossible for Chen Yuan, a freshman who had just come to the Taoist Academy, and Chen Yuan now only had the skill of making human skin masks. The dean was sure that Chen Yuan couldn't slowly accumulate contribution points in order to improve his strength, so the choice in front of Chen Yuan changed from many to one, that is, to exchange contribution points. Directly let the Daoist Academy take the initiative, through the advantages of resources and the contribution value system of the Daoist Academy, directly offset the advantages that Chen Yuan exclusively has, because the Daoist Academy needs Chenyuan's technology, and Chen Yuan also needs the resources of the Daoist Academy.

Chen Yuan smiled bitterly: "Do I still have a choice?" "Of course, you can choose not to change and spend a lot of time and energy to save slowly." Guo Rui still had a warm smile on his face, but in Chen Yuan's opinion, the image of the dean had successfully transitioned from a kind old man to an old fox with a wicked smile on his face.

Chen Yuan gritted his teeth and said, "Okay, I'll change it, but considering the uniqueness of this skill and its strong practicality, I ask to exchange it for 300,000 contribution points." Although he couldn't put forward other conditions, he could only obediently exchange his skills for contribution points, but Chen Yuan still had to fight for the greatest benefit for himself. The contribution value of the Taoist Academy is interconnected, and the items and tasks in the exchange hall and the task building are all summarized by the various palaces of the Taoist Academy into these two institutions, and the contribution value here is very large, so Chen Yuan will ask for 300,000 contribution points when he opens his mouth.

"That's impossible, although the skills you contribute are very precious to the Dao Academy, but the Academy's contribution value has always been a very important value system, and once it flows out in large quantities, it will cause turmoil in the system. What's more, if you are a freshman, the resources you can exchange are limited, and only by constantly improving your grade title can you be eligible to exchange for more and more advanced resources, and you can't use it now to get so many contribution points. You will be given a maximum of 100,000 contributions, and it will be distributed monthly, 3,000 per month, until 100,000 is distributed. Guo Rui heard Chen Yuan's request and immediately refused.

Chen Yuan suddenly stopped doing it, and said indignantly: "You are too ruthless in this cut, just cut me two-thirds, and the vegetable market is not so sloppy! Don't be sloppy with me, I believe that you have already seen the photos I assessed at that time, and you must have heard the specific situation from Dong Shi." This skill of mine is a priceless treasure for the intelligence organization of the Nine Heavens Domain, and it can save lives when used in the army's spies. You know how much it's worth. Well, let's take a step back. I want 150,000 contribution points, and I will pay it out on a monthly basis as you said, but 5,000 per month can't be less, what do you think?"

Guo Rui thought about it for a while, and finally nodded in agreement. Originally, Chen Yuan Lion opened his mouth to ask for 300,000 yuan to have more room for bargaining, in Chen Yuan's heart, in fact, it was already very good to be able to get 150,000, because this technology still had to be handed over to the Taoist Academy, it was too dangerous to hold it by himself, and it meant that he would not lack his own cultivation and his strength would rise at a high speed. Chen Yuan returned to the military palace with the dean's edict satisfied, and did not go to the exchange hall to exchange contribution points for the first time, but returned to his room first, took out the method of making the human skin mask that had been recorded for a long time, and then hurried to the exchange hall.

Came to the exchange hall of the military palace, Chen Yuan handed the handwritten message to the person in charge of the exchange hall according to the instructions of the dean, and after the person in charge identified the fake, Chen Yuan got a thumb-sized glass bottle, an envelope, and a white crystal card, under the guidance of the staff, Chen Yuan dropped a drop of his own blood on the card. A miraculous scene occurred, the blood was absorbed by the card, and blood-colored lines formed on the surface of the card. According to the explanation of the person in charge of the exchange hall, this crystal card records the amount of each person's contribution value, and the blood is to bind the identity in case it is lost.

According to the dean's order, the person in charge of the exchange hall exchanged 10,000 contribution points for a drop of Yanhua's milk, and put the 5,000 contribution points of the first month into the contribution card in Chen Yuan's hand, and the remaining 135,000 contribution points will be credited to this card month by month in the next two years and four months. As for the specific use of the milk of Iwanka, it has also been written in the envelope, and it can be said that the dean has thought very carefully. After getting what he wanted, Tatsugen handed the person in charge of the exchange hall a booklet detailing how to make a human skin mask.

Back at his residence, Tatsumoto couldn't wait to open the envelope and watch how the Milk of Iwaka was used. There are only two simple lines of instructions above, drop the milk of Iwanhua into warm water, and soak the whole body in the water that is infused with the milk of Iwanhua, and the method of use can be described as extremely simple.

Chen Yuan did not procrastinate, there was a large wooden barrel for bathing in every room where the students lived, and after adjusting the water temperature, Chen Yuan took out the glass bottle from his arms. When exchanging it, Chen Yuan put it away without careful observation, and now when he took it out, he saw that this Yanhua Milk really looked like some elemental essence. From the glass bottle, a drop of liquid the size of a fingernail can be seen sliding back and forth, and there are a few earthy yellow spots of light in the silver-white body, shining in the sunlight. It is not so much a liquid as a mixture of solid and liquid, with some resembling mercury similar to Earth, but not identical.

Uncorked the bottle, a natural aura came from the surface, and the power of the attribute caused the resonance of the aura, so a small aura storm appeared in the area of Chen Yuan's room, but it only appeared for a few seconds and disappeared into invisibility.

Tatsumoto drips the milk of Iwanka into a wooden bucket filled with warm water, and when the milk of Iwanhua comes into contact with the water, it renders the water into a faint silver color in an instant, and there are many earthy yellow particles of light in the silver. Chen Yuan took off his clothes, lifted his legs and stepped into the bucket, slowly and completely immersed his body in the water mixed with the milk of Iwanhua.

Closing his eyes and sinking into the water, Chen Yuan didn't feel anything special in the first few seconds, but after a few seconds, a tingling sensation came from every skin on his body, and it became more and more intense. Chen Yuan opened his eyes with great difficulty, and was surprised to find that the earthy yellow light particles that were originally scattered all over the barrel had gathered all over his body at some point, and the light continued to flicker, and every time it flickered, it was as if a powerful shock wave was impacting the body at the location.

These particles of light flickered quickly, and the impact was wave after wave. In just five minutes, all the capillaries on the surface of Chenyuan's skin on his body were ruptured, and the blood instantly stained the water in the wooden barrel. But at this moment, a faint silver halo lit up, like a shepherd driving a flock of sheep, this halo drove the blood in the bucket back to Chen Yuan's body, because these blood had been in contact with the earthy yellow light particles and silver water in the bucket, more or less with some elemental essence back to the body. The milk of Yanhua is the result of the fusion of water attribute and earth attribute essence, and the water attribute has a healing effect, and soon the wound on Chen Yuan's body recovered.

After that, there is a new round of impact, and so on, the elemental essence is transmitted to every part of the body through the contamination and flow of blood, and the body is strengthened, and even the most difficult organs will be strengthened together, which can be said to be a very comprehensive strengthening method.
