Haige asked stupidly, "So, why can Mr. use the filter again this time?" ”

Li Zhengsong replied: "There is only one kind of filter material that can be used to filter the purple apricot leaf flesh, and that is the root of the purple apricot tree. The roots and leaves come from the same tree, so they naturally do not interact with each other, and chemical reactions occur. But even on the U planet, the purple apricot tree is a very special tree species, with a strong sense of self-protection, which is reflected not only in the way the leaves grow, but also in the roots. Its roots are sharp and thin, and they contain poison that no matter how careful they are, the person who digs it will stab the stinger, and that poison, Wedel says, he can't ...... out."

"Professor Li, you ...... What do you say?! ”

Hai Ge was stunned, he couldn't think of how hard to find the filter, the reason was the toxicity of the roots of the purple apricot tree!

Li Zhengsong said: "Wedell has told us a long time ago that he knows very well how to solve the problem of refining super metal, and he doesn't mind risking his life, but there is still a big thing to be done, and when the big thing is done, he can do whatever he wants without worry." ”

"Another big deal!" Hai Ge shouted indignantly: "How many big things does he have that he can't say? What is more important than life? If a man dies, he can't do anything! ”

Li Zhengsong turned his head abruptly and looked at him with strange eyes: "The big thing that Wedell is planning, everyone in the light of salvation knows it, is to find a qualified pilot for the Huoyiren. When you appear in the torch living area, we see you walking in the direction of Woxiang Mountain from the surveillance video, and we know that Wedel's big event is almost complete. ”

"Looking for me, is that the big thing that Mr. needs to accomplish?" Hai Ge was like a blow to the head, and he was speechless for a while.

Li Zhengsong said: "The poison of the roots of the purple apricot tree is chronic and highly toxic, and the poisoned person will not die immediately, but will gradually lose his strength." Wedel took the roots in front of me, and I advised him to use electronic tools, but not only did he disagree, but he didn't even wear gloves, saying that he was afraid of damaging the roots. Even if a thorn is broken, the roots of that tree will be useless. He dug very carefully, but I still saw a few thorns stuck in his fingers, and I think he was poisoned......"

"No, it won't!" Hai Ge shouted categorically, "The Purple Apricot Tree is the Tree of Hope, it is designed to bring hope to the people of the U Star, and even the badge symbolizing the U Star is used as a marker, how can it kill the last survivor on the U Star?" I'm going to Mr. Weddle! ”

He rushed out without saying anything, and Li Zhengsong hurriedly got up from the small stool and grabbed him.

"Kid, the surface world is in chaos right now! The police and government forces are searching everywhere for the whereabouts of the aliens, almost all the exits of the underground plant kingdom have been blocked, and Wedel has left me with the electromagnetic wave emitter that built the light-controlled corridor, you can't get out without me! ”

"This ......" Hai Ge stopped and looked at Li Zhengsong pleadingly, his eyes covered with a layer of sparkling tears, "Professor Li, then you let me go, I can't let Mr. take risks alone!" ”

Li Zhengsong's eyelids drooped and said, "The world is so big, even if you go out, what can you do?" Finding someone is like looking for a needle in a haystack, you're just wasting your time. Besides, you're leaving for Australia at dawn, do you want to disrupt Wedel's plans? ”

Hai Ge was stunned, "You also know about this?" ”

Li Zhengsong let go of him, spread his hands and said: "The old era of the underground plant kingdom is over, and the new era without Wedel is about to begin." After the success of the super metal test, a large area of purple apricot trees has been planted in the primeval forest in front of the iron smelting workshop, and after seven days, we will be able to pick enough purple apricot leaves, and then send them to the metal material processing plant in Woxiang Mountain, and start the mass production of super metal according to Wedel's formula. On the other hand, after decades of exploration, the ground port built in the core ocean of the earth, in addition to the three variable star spacecraft that can pass through the entire earth's strata, has also created a number of engineering spacecraft that can be invisible in space. Soon we will enter the universe from the center of the earth, where we will start the construction of the triangular orbit. Those in the Global Consortium of Science and Technology who respond to us are not part of the Light of Redemption organization, but will do their best to save the planet. They can't go underground for any reason, but they can act as a powerful response for us! ”

This news shocked Hai Ge somewhat, he had always thought that the members of the Redemption Light Organization were limited to those who entered and exited the underground headquarters, but he didn't expect that there was an external response on the ground. In the past, he really underestimated the strength of this organization, and also underestimated Wedel's influence on the earth.

Li Zhengsong's big hand pressed on his shoulder vigorously, "Child, go do what you have to do." Be sure to peruse the information that Weedel left on the hard drive, and when we meet again in ten years' time, you will be honorably the first generation of citizens of the new society on Earth, and you will be given the Hope identity chip. ”

"Ten years later? Do you mean when the Flame Man broke away from the hull of a yacht and turned into a spaceship to tow Earth into orbit? In Haige's gloomy heart, a little light appeared.

Li Zhengsong nodded, picked up the metal crutch leaning on the side and walked towards the door of the workshop. His back was bent violently, and his legs were shaking, showing his old age, but when the crutches were pointed down on the uneven ground, the sound was so sonorous and powerful, as if it were actually a spear, and the old man was holding it tightly towards the battlefield.

"Professor Li," Hai Ge couldn't help but shout, and he had one last question: "Why can't I watch the last super metal test process?" ”

The crutches of "Dangdang" stopped cleverly, and the old man replied with his back to him: "I think you will find the answer from the hard drive left by Wedel." ”

After Li Zhengsong left, Hai Ge also left the workshop. He didn't turn off the lights, thinking that if the lights were always on, Wedel would always be there.

Tomorrow is the end of the magical underworld, and we should go back to the primeval forest tonight. When you get to the ground, is it possible to turn back? Once the escape journey to Earth begins, this place will cease to exist, except for the glorious U-star creature incubator like a crystal palace, and the frozen embryos in the glass lattice, all U-star creatures will be wiped out again, this time, including some Earth humans......

But when Haige burrowed into the dense bushes and stood in the primeval forest, he found that the path he had walked was gone, and it seemed that it had never been developed and no one had ever visited.

"Professor Li Zhengsong......

Hai Ge understood that Li Zhengsong had hidden the path when he left, and he should have sealed the area where the workshop and the villa were located according to Weidel's intentions, so that no one could approach it again. That trail was a shortcut through the primeval forest, and it must have used some kind of alien technology that he didn't know about, otherwise how could such a huge forest be able to go from beginning to end in just an hour?

The forest is quiet, and this quiet, unlike the desertion in the villa and the solitude in the workshop, is created by the chorus of various insects or animals that are active in the middle of the night. You can still see the glare of light from different organisms, reflecting the trees in a strange light.

As Li Zhengsong said, the purple apricot grove has expanded, driving away the territory occupied by flowers and plants before, and it is so big that it is impossible to see the edge.

Haige plucked a thick, hard purple apricot leaf from a branch and treasured it in his pocket.
