"No problem." Wan Chenhuang's eyes sparkled, and he nodded in delight: "Lin Tao, let alone a year, at most three months, within three months, the influence of Mengchen Chamber of Commerce will spread throughout the Black Dragon Mountain Empire."

Three months?

Lin Tao waved his hand: "Three months is too short a time. What I need is a chamber of commerce that truly has a huge influence, not an empty shell."

How big is the Black Dragon Mountain Empire? Lin Tao found the star map at the Mihuan Star Telepathic Academy. Among all the empires, this universe country is not big, it is just a small universe country. Even so, it has more than a thousand inhabited planets. This scale is even not less than the Interstellar Federation where Lin Tao is.

Three months is too short a time. By that time, Lin Tao suspects that such a chamber of commerce that was hastily brought to the public will not be able to withstand the test of time and will eventually disappear into history.

What Lin Tao needs is the Mengchen Chamber of Commerce, not just the face of the Black Dragon Mountain Empire, but also an important connection between him and Lu Mengchen. If it is just an empty shell, Lin Tao will never agree.

What's more, in Lin Tao's future vision, Mengchen Chamber of Commerce is not just a pharmaceutical chamber of commerce, but will also be the first chamber of commerce in the universe to issue mechas.

Mechas are special weapons that are no less powerful than telekinetic protective gear. Anyone, whether or not they are a telekinetic master, can operate this type of machine and travel through the air and the universe.

The arrival of mechas is bound to bring another change to this universe.

"A chamber of commerce that truly possesses great influence?" Wan Chenhuang frowned. As the emperor of the empire, how could he not hear the hidden meaning behind Lin Tao's words? If this were true, wouldn't the chamber of commerce be able to influence the status of their royal family in the future? For a moment, Wan Chenhuang hesitated.

Lin Tao glanced at him and immediately smiled: "We can sign a contract. Mengchen Chamber of Commerce will never affect the status of your royal family. Similarly, your royal family cannot influence the commercial trade of the Chamber of Commerce too much."

After a pause, Lin Tao continued, "Well, I don't want the previous situation on Taotao.com to be used by your royal family to control Mengchen Chamber of Commerce."

Previously, the Ninth Prince used the influence of the Black Dragon Mountain Empire to remove the medicines from the Mengchen Chamber of Commerce’s Taotao website for a long time.

"This level will never appear." Wan Chenhuang said repeatedly.

Lin Tao waved his hand: "No, let's sign a contract first. Besides, the conditions you can agree to may only be realized on you, the emperor. Once the Black Dragon Mountain Empire changes its owner, perhaps our contract may also be terminated."

“This…” Wan Chenhuang frowned, not knowing what he was thinking about. He suddenly sighed, “Lin Tao, since you have seen the Fifth Prince, you should also know my current situation. My life span should not exceed ten years, and after being poisoned by the Ninth Prince, I may not even survive five years…”

At this point, his eyes tightened and he stared at Lin Tao: "You have also been in contact with the fifth prince. If he is designated as the next emperor, what do you think..."

In order to retain the Mengchen Chamber of Commerce, Wan Chenhuang even went so far as to ask Lin Tao about the next heir to the throne of the Black Dragon Mountain Empire.

Lin Tao raised his eyebrows and stared at Wan Chenhuang. After realizing that Wan Chenhuang's expression was not fake, he laughed again: "I remember that before coming to the capital planet, the fifth prince once entrusted me to develop a medicine for you to prolong your life..."

"No matter how long my life is, I can only manage this empire for ten or eight years at most. I have been the emperor of this universe for a long time, so a few decades won't make a difference." Wan Chenhuang shook his head.

Seeing that he was planning to give up, Lin Tao was stunned for a moment. Then he smiled slightly, stretched out his right hand, and shook his five fingers: "Five hundred years, is that enough?"

"Huh? Five...five hundred years..." Wan Chenhuang was stunned at first, then dumbfounded. He stood there with his eyes wide open, as if he couldn't believe it.

"Five hundred years. As long as you can provide enough medicinal herbs and rare items, I am 50% sure that I can prepare a special potion that can extend your life by 500 years." Lin Tao said.

Lin Tao's confidence did not come from his understanding of potions, but from the fact that in later generations, the Interstellar Federation he belonged to had developed a potion that could extend life by five hundred years.

The humans in this universe are different from Lin Tao, but if Wan Chenhuang is willing to provide enough basic samples, plus enough materials, and with the assistance of Zhe, Lin Tao dares to guarantee that he has at least a 70%, or even 80% chance of developing the same medicine.

"Hiss~" Wan Chenhuang took a long breath, his pupils contracted and his mood took a long time to calm down.

It's not that Wan Chenhuang didn't look for pharmacists before, and each of them was a master pharmacist. However, these people could only develop potions that were only 20 to 30 years old at most. Even after exhausting all his connections, the one master pharmacist he found could only produce potions that were only 50 years old.

Now, Lin Tao said he would extend his life by 500 years. His strength is even higher than that of a master of alchemy.

After looking at him again and again, seeing that Lin Tao's expression did not seem fake, Wan Chenhuang exhaled again, and then his expression relaxed. Even so, his words were still a little slow, as if he had stuttered: "Lin...Lin Tao, you...you can really...can you prepare a potion that can extend your life by five...five hundred years?"

"You don't believe me?" Lin Tao asked with a smile.

"I..." Wan Chenhuang's eyes flickered, and after finally suppressing the anger in his heart, he spoke smoothly: "I... I believe it."

If it was someone else who spoke, Wan Chenhuang might still be skeptical, but now that Lin Tao had spoken, he had no choice but to believe it.

Mengchen Chamber of Commerce is a pharmacy chamber of commerce founded by Lin Tao. The first thing they release is Mengchen No. 1 Potion, which has been rated 10,000 points by the Adventurer's Association.

How many pharmacist masters can do this? After catching his breath, Wan Chenhuang asked in a deep voice: "Lin Tao, if you need anything, just tell me and I will have someone bring it to you as soon as possible."

"First, give me ten samples of your blood. As for other resources, I will send you a list. If you can find them, please send them to me immediately. Yes, send them to this spaceship." Lin Tao said.

A blood sample is nothing more than extracting blood, but when it comes to life span, it involves genes, and some bone marrow needs to be extracted. Bone marrow sampling is different from ordinary blood sampling. The direct extraction process is painful, and not something most people can endure, let alone extracting ten samples at once.

Wan Chenhuang was tough. He gritted his teeth, cold sweat on his forehead, and endured it.

After taking the samples, Wan Chenhuang immediately asked Lin Tao for the list. Lin Tao had already prepared the contents of the list. After all, he had thought about preparing this kind of potion as early as when he was the Grand Speaker of the Interstellar Federation. However, in order to capture the shadow, he went to another place and put the matter on hold temporarily.

Now that he has the opportunity, Lin Tao naturally plans to prepare the medicine.

At the same time, he would prepare two more, one for himself and the other for Lu Mengchen.

Of course, Lin Tao would not rush to use it on the two of them. Instead, he would wait until it succeeded, then he would ask Wan Chenhuang for more materials so that he could concentrate on researching the potion that would extend a thousand years of life. If the potion was successful, he and Lu Mengchen would take it on the spot. Unless they could not research it out, they would temporarily use the potion that would extend a five-hundred-year lifespan.

After all, every time the potion is used, it will change the genetic changes in the body to some extent, so the preparation of the potion next time will be different. In order to avoid trouble, Lin Tao plans to prepare a life-extending potion of a higher age at a time.

Lin Tao prepared such a high-year-old life-extending potion not because he was afraid of death and wanted to live longer, but because he wanted to spend more time with Lu Mengchen. Because apart from mecha driving and research, it is basically impossible for him to spare time to be with Lu Mengchen.

As soon as Wan Chenhuang left, Lin Tao immediately closed the hatch of the spacecraft and appeared in the laboratory again.

"Zheng." Lin Tao called out.

Before Lin Tao could shout, Zhe had already jumped out from his hiding place: "Lin Tao, can the life-extending potion really extend your human lifespan by 500 years?"

To be honest, Zhe has seen quite a few humans, but unfortunately the lifespan of these humans is always not as good as that of the mechanical race. Even if they practice mind power, they can only live for about two to three hundred years at most. Once they reach these age groups, they are almost at the end of their lives, like dead people.

While following Lin Tao, its knowledge increased a lot. It not only saw the existence of Guda's shadow, but also the combined form of Zhuo and this universe.

Psychic power, psychic energy guide armor, psychic energy contact objects...

All of this, even the mechanical clan with a comprehensive database has never come into contact with it.

Even, Zhe had heard that there were mechanical races in this universe whose appearances were somewhat different from theirs. As a member of the mechanical race, how could he not want to see them?

At this moment, Zhe really hoped that Lin Tao could live another 500 years, so that he could stay with Lin Tao for a long time beyond the 100-year contract.

Every day's new news is like an adventure, this is the day that every mechanical person longs for.

Lin Tao nodded: "Now help me analyze these blood samples and these bone marrow samples."

"Okay." After Zhe's core sphere flashed downward, it shot out twenty beams of light at once with a whoosh, as if it wanted to analyze all the samples at once.

"This..." Lin Tao blinked and asked in confusion: "Zhen, this is just a sample from one person. You only need to analyze one of each."

"Uh~" The light shot out by Zeng condensed, and then he smiled awkwardly, then retracted the remaining eighteen rays of light and quickly analyzed the blood and bone marrow samples.
