If Wedel wants to go deep into the inner core of the earth to open up an underground plant kingdom and awaken the frozen embryos hidden in the cargo bay of Variable Star 1, he must unite with the earthlings, and these people can only be scientists who know advanced science and technology.

Wedel admired the ice castle material independently developed by the earthlings, and thus met the inventor of the material, Professor Li Zhengsong, and the two became friends and established a cooperative relationship.

Li Zhengsong was very surprised to hear that Wedel planned to build the base of the organization that saved the earth in the center of the earth, he thought that this idea was not boundary, and might make the earth fall into internal and external troubles, but he could not resist the temptation of alien technology, and was eager to try.

Wedel is a man who can wade through the molten iron and nickel, and if he does use the magical U-star drilling equipment to open a tunnel to the center of the earth, he can act as a living human detector, building a bridge between humans and the inner world. So the arrival of this alien brought light to the scientific community's geocentric exploration program, Li Zhengsong was overjoyed that he would finally overcome this difficulty, and told his son, Li Zhongyuan, a materials expert who specializes in the research of new heat-resistant materials, about this great news.

Li Zhongyuan inherited his father's talent and intellectual spirit, but he was eager for quick success, and was determined to join politics and get a half-official position in the Earth Coalition Government.

The ice castle built by Li Zhengsong to save the earthlings eventually became the exclusive property of the wealthy class due to the high cost, which made him deeply remorseful, and he also saw the unbearable fact that the scientific community had been used by the United Earth Government and no longer worked for the welfare of the common people, so he joined forces with Wedell to establish the Redeeming Light Organization.

In order to devote oneself to scientific research, the birth of the Light of Salvation is classified as an absolute secret, and no member of the organization is allowed to divulge a word to the outside world, especially to those in power. They have a lot of collaborators in the global science and technology federation, but those people will not stand up until the critical moment.

The Light of Salvation is only an organization, not a state, there is no legislation in the organization, there is no tyrant rule, even if someone really violates the organization's constitution and tells the secret, Wedel will not use extreme means to punish him, all order can only be maintained by the personal morality and sense of mission of the members of the organization.

Li Zhengsong knew Li Zhongyuan very well, and after the Light of Redemption was established, he regretted telling him about Wedel, but the words he said were like water spilled and could never be recovered, so the only remedy he could think of was to ask Li Zhongyuan to also enter the underground world, so that he could always keep an eye on him and prevent him from doing bad things that violated the purpose of the organization for personal gain.

Li Zhongyuan stands between the global science and technology federation and the light of salvation, but he is actually very contradictory. The former can not only provide him with sufficient conditions for scientific research, but also pave a glorious career for him. But the latter can only meet his scientific research needs, and maybe he will have to stay at the center of the earth for the rest of his life. You must know that studying the inner world of the earth is completely different from living in that closed world from now on, never seeing the sunlight on the ground again.

What's even more terrifying is that when the earth engine starts to work, the underground plant kingdom will be destroyed, and as an expert in researching the engine, he must stay with the large army, isn't that certain death?

Li Zhengsong said to Hai Ge: "For so many years, I have been monitoring Zhongyuan, for fear that he will make a mistake. Although the Light of Redemption does not have any clear punishment clauses for traitors, if such a person does appear, he will still not end well. It is a land of freedom, where there is no legal system, and everyone is the owner of the torch living quarters, which seems to be the ideal of democratic coexistence, harmonious and harmonious, but in reality it hides terrible dangers. Because everyone can threaten the lives of others, and there is no legal responsibility for killing someone, if one person provokes the masses, the light of salvation can easily gather the strength of the crowd to execute him. ”

Hearing Li Zhengsong say this, Hai Ge had already sensed that something was wrong in his tone, and hurriedly asked, "So in the end, did your son still reveal the information of the underground world to the people on the ground?" ”

"Hey~" Li Zhengsong lamented: "Zhongyuan has worked in obscurity in the light of salvation for twenty years, and has obtained all the information on the construction of the ground spacecraft. Most importantly, he learned from Weddle how to grow refractory plants and extract plant fibers from leaves, which were then fused with metal powders to create refractory titanium. To tell the truth, these twenty years have been nothing more than a taste of courage for him, he is really a qualified politician, he has the ability to hide all his inner activities, and on the surface he obeys me as a father, but when the time comes, he starts to take action......"

"Professor Li, if I guessed correctly, the day and a half I fell asleep was the time when Li Zhongyuan fled?" When she asked this, Haige's heart trembled.

Li Zhengsong covered his face with his bruised hands, and sorrow came from it. Haige couldn't see his expression, but she could imagine his old tears. Do you still need to ask? Li Zhongyuan is dead, and it is unknown whether he was executed en masse by the public or for some other reason, but one thing is certain: the secrets of the underground plant kingdom have been revealed, and now the United Earth Government knows of the existence of this underground world.

After stabilizing his emotions a little, Li Zhengsong wiped away his tears and said, "That bastard thing took the hard disk and refractory plant seeds that stored the blueprints of the Earth Navigation Spaceship, and stole a Variable Star Earth Navigation Spaceship from the Earth Navigation Harbor, trying to escape from the underground plant kingdom before dawn. He had to pass through the high temperature zone of the outer core, but he didn't build an electromagnetic wave emitter in the light-controlled corridor, that thing was the key to open the door to the underground plant kingdom, Wedel never left easily, Zhongyuan didn't dare to go to Wedel to steal it, so he thought he was smart and quietly made a ...... himself"

Hai Ge shuddered, thinking that it was a 6,000-degree high temperature molten slurry! If there is a problem in the light-controlled corridor, Li Zhongyuan's fate will be burned to the point that there are no bones left!

Sure enough, Li Zhengsong said: "Wedel taught us a lot of U-star technology, including the construction of channels with the help of the particle properties of light. Our U-star friends are selfless and never hesitate to give, but those who learn from him must also have the true ability to understand and truly learn to operate. Chungwon had been planning for 20 years, and knew that the light-controlled corridor was the key to leaving here, so he spent a lot of thought on the electromagnetic wave transmitter, and after making the finished product, he went through many tests, and was confident that he would succeed, so he set a time to leave the underground world. ”

"But in the meantime, you and Mr. Weddle weren't aware of his anomaly at all?" Hai Ge asked gloomily.

Li Zhengsong said: "Naturally, there is. No matter what happens in the underground plant kingdom, it can't escape Wedel's eyes, and he has warned me many times that Zhongyuan's ambition is not small, and sooner or later he will sell the light of salvation in exchange for his own interests, but I always protect him in various ways and defend him. Hey, he's also my son, and he's almost fifty years old, so even if he returns to the ground, how can he start over? As a result, I was only negligent for a moment, and he ....."
