As a member of the mechanical family, analyzing the sample is not a difficult task. In a short while, Zeng had thoroughly scanned and analyzed it, and the result appeared in the form of a light curtain in the air.

Lin Tao looked and found that, as expected, the genes of the humans in this universe were very different from his. Fortunately, he was well prepared and asked Wan Chenhuang to prepare ten samples in advance.

While Wan Chenhuang had not yet sent over the resource materials, Lin Tao also began to ponder over the sample.

It has to be said that although there are some differences between the two groups of humans at the genetic level, when you get to the bottom of it, they also have many similarities.

As for life span, Lin Tao already has two conclusions in his mind.

One is to use the genes of other species to extend the longevity genes in Wan Chenhuang's body. In this way, Wan Chenhuang can have the longevity of that species.

This method is a good one, but it also has a disadvantage, which is that it is very easy to produce genetic mutations. The final result will be just like Xinya, who eventually becomes neither human nor creature.

In an instant, Lin Tao threw this method out of his mind and thought of a second way.

The longevity gene affects human lifespan, but under normal circumstances, this gene will not disappear at will. Therefore, Lin Tao’s second method is to delay aging, which is also the method adopted by Lin Tao’s universe.

Wan Chenhuang is not too old, and his metabolism is still normal. However, after he was poisoned, his organs were damaged, causing drastic changes in his body's cells, which is why he feels that he only has a few years left to live.

Therefore, in order to delay Wan Chenhuang's aging, Lin Tao thought of repairing his important organs and then activating and stimulating the cells. This would not only restore Wan Chenhuang's youth, but also continuously stimulate the cells to keep them in their strongest state, thus achieving the effect of prolonging life.

The second method required a large number of rare objects, so after some consideration, Lin Tao made another list of rare objects. Regardless of whether the Black Dragon Mountain Empire had them or not, he asked for them all. In addition, he added some rare objects that he might need in the future to the list.

At the other end, the Royal Palace.

Wan Chenhuang sat on the throne without saying a word. Beside him stood a number of old men. Some of these people were the ones who survived the insect man 'Hong Yun' at that time, while some were trustworthy people selected by him.

Of course, the status of these newly promoted people is not the same as that of the remaining old people. Standing next to each other, they are much more cautious.

Wan Chenhuang didn't say anything, and these people didn't dare to speak either. The old ministers also didn't speak easily.

After a few beeps, the sound of a wristwatch communication came out.

The sudden sound made everyone in the palace change their expressions and look around, trying to see who was so blind as to make their watches ring at this moment.

Fortunately, the sound of the watch came from Wan Chenhuang's wrist.

Wan Chenhuang also frowned, raised his hand and saw that the message came from Lin Tao. His face suddenly changed and he hurriedly opened his watch.

Seeing his expression, the officials present were all so nervous that their hearts were in their throats.

After clicking it, the message only contained a short sentence and a list.

“Try your best to get the rare items on the list.”

Seeing this news, Wan Chenhuang couldn't wait to open the list again. As soon as he saw it, his brows furrowed again: "These..."

Wan Chenhuang looked up at the people present. His eyes fell on one of them and he asked in a calm voice, "Have you finished counting the resources in the warehouse?"

"I haven't received any news yet, but it should be about the same." This old official was one of the survivors. He was also quite familiar with Lin Tao's request for the rare object. After hearing Wan Chenhuang's words, he immediately operated his watch.

Not long after, he exhaled lightly and reported quickly: "Emperor, the inventory has been completed. Except for a few rare items in the warehouse, the rest of the items are in a certain quantity. We can send the items to the spacecraft platform immediately."

"Okay." Wan Chenhuang was delighted and nodded repeatedly. After nodding, he sent the list in the watch to the old minister again: "Have someone count it again. If there are these resources, send them over as well."

"Well, give each of you a portion of the resources you owe." After a pause, Wan Chenhuang said in a deep voice, "My fellow ministers, this situation is rather special. Just think of me, Wan Chenhuang, as borrowing from you. After this matter is over, I will return it tenfold."

"Your Majesty, you are the emperor of the Black Dragon Mountain Empire. No matter what you say, if you need us, we will deliver the items on the list no matter what the situation is."

"I am a minister of the Black Dragon Mountain Empire. How can I lend it to the royal family? As long as the emperor needs it, let alone these material possessions, even my life can be offered with both hands."

…

One by one, the old ministers expressed their loyalty.

Wan Chenhuang nodded with satisfaction, and while signaling the newly joined ministers to deliver the resources to the spacecraft platform, he kept the old ministers behind.

Before long, only the old officials were left in the palace.

"Emperor, is what Lin Tao said true?" At this time, an old minister finally couldn't help but ask.

Suddenly, everyone's eyes fell on Wan Chenhuang.

"Even if Lin Tao is just trying to cheat us of some rare resources, what can we do?" Wan Chenhuang said softly: "I have already promised to give him some rare resources, but now he has made such a request. I think that with Lin Tao's identity, he will not deceive us, and..."

Wan Chenhuang looked around and said, "Has everyone forgotten the Mengchen No. 1 potion from the Mengchen Chamber of Commerce? This potion was also made by Lin Tao."

"Your Majesty, it's not that we doubt Lin Tao's words, but the potion that can extend one's life by 500 years may not be concocted even by the master of potions. He..." The old minister frowned.

Five hundred years. Thinking of this period of time, not only this old minister, but even the other ministers present felt shaken in their hearts.

After all, they once asked a master of alchemy for help, but the other party only proposed a potion that could extend life for fifty years. Perhaps the other party had a potion formula that could extend life for over a hundred years, but I'm afraid that few people in the Adventurer's Association could make a potion that could extend life for five hundred years.

And Lin Tao is really too young.

Wan Chenhuang could naturally hear what these ministers were thinking, but at this point, he had no choice. Moreover, this was a request made by Lin Tao himself.

If Lin Tao just wanted to cheat some resources, he would have agreed to it as soon as he was willing to give away a rare item.

I think Lin Tao must have a certain degree of confidence to make such a request.

Five hundred years. Thinking of this period, Wan Chenhuang couldn't help but take a breath. If he could have the governing authority of the Black Dragon Mountain Empire for another five hundred years, he would definitely be able to upgrade the Black Dragon Mountain Empire from a small universe country to a large universe country. Even if it is not international, it can also become a medium-sized universe country.

Of course, with the participation of Lin Tao and Mengchen Chamber of Commerce, the time it takes to become a large cosmic country will be greatly shortened.

Just like the old ministers present thought, Wan Chenhuang was also worried. After all, Lin Tao only promised a 40% chance. Thinking of this, he sighed deeply.

If it really doesn't work, then these rare items will be given to Lin Tao in advance.

As for the next emperor, he had already made a choice, and that was the Fifth Prince. The Fifth Prince had a good relationship with Lin Tao. If he came to the throne and followed his instructions, the Black Dragon Mountain Empire would survive this insect-man invasion in no more than ten years.

Everything was planned, and his heart calmed down. If Lin Tao could really develop a life-extending potion, that would certainly be a good thing. If he failed, he already had plans for the next step, and it would not affect the development of the Black Dragon Mountain Empire at all.

…

…

Even if the old ministers took action, the rare resources on the list were still in short supply, especially one or two of them, which made Lin Tao frown.

"Lin Tao, can't your previous atomic transformation solve the problem?" Zhe's core sphere said after scanning the resource materials one by one.

"Do you have a better idea?" Lin Tao asked.

"It's not a good idea. To use your human words, the success rate is not high." Zhe said.

I don't know how it happened, but Zeng learned human language and used words with a low success rate for things that he was not sure about but could pass in theory.

Lin Tao smiled slightly, without pointing it out. After a moment of hesitation, he decided on the spot: "Then let's give it a try."

As a member of the mechanical clan, Zhe has conducted many calculations in terms of theory and speculation, while Lin Tao relies on experience. There is still a lot of gap between the two, so in this process, Zhe will provide the theoretical data and Lin Tao will do the work himself.

The process went surprisingly smoothly, and Lin Tao actually successfully synthesized several new types of replacement items. Even Lin Tao himself couldn't believe it.

With the resources in hand, the following process went much more smoothly. Through joint research by both parties, Lin Tao successfully prepared the life-extending potion.

Since this medicine uses Wan Chenhuang's genetic sample, it can only be tried by Wan Chenhuang himself.

When Wan Chenhuang came to the Salon spaceship again, he still looked incredulous after hearing that Lin Tao had successfully prepared the medicine.

"Lin Tao, is this... the potion that can extend life by five hundred years?" Wan Chenhuang took the test tube. Inside the test tube was a transparent potion. If it weren't for the horizontal surface, it would be impossible to distinguish the two.

"I'd like to state in advance that this medicine uses your genes, so we have no way to test it." Lin Tao said, "But after many speculations, this medicine has a success rate of more than 70%."

70% chance? Wan Chenhuang's hands trembled, and he asked repeatedly: "What if it fails?"

“If you fail, just think of it as taking a tonic. The rare resources in it can repair your internal organs and let you live a few more years.” Lin Tao said.

This potion uses a lot of rare ingredients. Even if it fails, it can still repair organs. Of course, all medicines are poisonous. While repairing Wan Chenhuang's organs, it also has a certain effect on the cells in his body.

Therefore, the decision of whether to take the medicine was finally returned to Wan Chenhuang.
