Toka came to Treant City to start looking for a job, he worked hard in each of them, and he also made many friends, and once he attended the funeral of another friend's father with his friend, which was the first time he saw the Treant die.

When Toka and some of his friends arrived at the funeral, they saw the old tree man lying on his side on a high circular platform, his eyes were blank and his whole body was black, and the rhizomes and leaves that had drooped down his head were now bare rhizomes, and they were gray-black, and he looked very healthy.

A circle of adult treants casting spells underneath the platform used magic to create a blinding white light around the circular platform in order to allow the elderly treants in the center of the platform to receive more light, which could temporarily extend his lifespan.

"My Treant Children, my Treant friends, today is not a sad day, it is the day I return to the earth, we Treants come from the earth, and will eventually return to the earth, we love this land, today I will use my body to nourish this soil, in order to repay its nurturing grace to me, and please remember that the land is the mother of our life, we must always love the earth under our feet. Please use light magic to contribute to the natural cycle of our land, and resist dark magic, always remember that fire is an evil thing, and it can only bring disaster to us. I've spent my life fighting against nature's thunder and lightning, and now that I've paid off, my friends and I have proved that we can fight lightning without dark magic...... Treants don't die, they just return. ”

After finishing speaking, the old treant on the circular platform lay down, and then the magic treant in a circle stopped casting the spell, and then the old treantman's body quickly turned into gray-white powder, and after a gust of wind, it was scattered in the air.

After Toka attended the whole funeral, he felt a lot of emotion, he knew that the words of returning to nature said by the old tree man on the stage were comforting, in fact, he had just left this world, and he began to sobble secretly at this moment.

Toka has been working hard all the time, and after a long time, he is now the elder of the highest magic school in the Treant Kingdom, mainly responsible for the research and development of new magical materials, which are cutting-edge technology in the Treant Kingdom, and the research results are usually high-level magic materials that attract the attention of the world.

When everyone saw this, they couldn't help but be amazed by the strange form of civilization of the treeman race, and they were also amazed by the clear and perfect memory bank of the treeman, but in addition to sighing, there was a question that had been hovering in Cheng Shi's mind, he saw that the treeman named Toka was getting older and older, and the houses in the treeman city were still made of curved tree trunks, these houses seemed to grow out of the ground, and there was no trace of artificial construction at all, and there was no kind of road paved with stone in the city, what they called the cityIn fact, it is composed of tree houses in the forest, and there is no modern means of transportation, and now the remains of civilization on the tree man planet are clearly modern high-rise buildings, and there are many high-rise towers made of cutting-edge materials. This couldn't help but make Cheng Shi very confused.

The hologram screen from the Treant Toka memory continues to play.

One day, while the elderly Toka was carefully instructing his students in magic experiments in the magic laboratory, a man came over to him and told him something that made him immediately alert.

Treants hardly get sick and are occasionally harassed by some bugs, but let the sun shine in direct sunlight for a while and you'll be fine. So for thousands of years, the Treant race has been

Living peacefully on this planet, the biggest trouble they encounter is nothing more than the forest being struck by nature's lightning and igniting a fire, and there have been tragic incidents of burning the whole city. Other minor troubles are nothing more than mischievous treemen dying to study fire magic, and have also caused small-scale forest fires.

And this disaster did make them a little helpless, the tree people suffered from a terrible disease, all the tree people who contracted this disease, after a while, the body will fester, no matter what magic they use to repair the festering body, it will not help, the ulceration will always happen, and the speed will get faster and faster, until it is too late to repair, they will eventually die, and this process is only about a few dozen days.

At first, it was thought that this was the result of some Treants studying the Dark Arts, but Toka led some authoritative Treant Magic experts to study the experiments, and found that this was not something that the Dark Arts could do. Later, the problem was not solved, and the tree people began to suspect that the forest environment they lived in was diseased, so they began to move out of the forest, to the grassland, and gradually built stone houses, and finally they found that the situation was better, so they shoveled all the plants on the ground of the grassland city, and paved roads on the ground to prevent plants from growing out of the cracks in the stones, which is the first generation of tree man cities.

However, the good times did not last long, and the ground of the stone city began to pour out black sticky substances out of thin air, which destroyed many of the city's roads and houses, and soon the terrible disease began to spread. Later, the black matter became more and more crazy, and many stone cities were severely damaged.

The Treants didn't know where this black substance came from, but they knew that it was the root of all evil, and they couldn't stop it from pouring out, so they began to do everything they could to isolate themselves from it.

At this time, although Toka was an old man who was about to die, he was still serving at the highest magic school in the Treant Kingdom, and was in charge of the research and development of high-grade magic materials. They researched a variety of materials to isolate the black substance, but they eventually developed the flying machine, but they soon discovered that the Treants would die of hunger and panic when they were in the air, so the project was terminated.

Since the Treants can't escape the ground they live on, the only way to do this is to develop high-strength materials.

Later, Toka gathered all the high-level magic material engineers in the kingdom, including some folk engineers who studied black arts, and they had to unite to fight for the survival of the Treant race, and finally succeeded in researching the Wizard Pioneer No. 1, which is the kind of strong interaction material.

However, the production of Wizard Vanguard 1 not only requires a lot of magic materials, but also has a very low yield rate, so it is extremely difficult to save the Treant race with this material.

Later, a magical materials research team developed a magical nutrient solution that could preserve the trunk of the treant for a long time, making it possible for the treant to escape from the ground in a flying machine, but the majority of the treants objected, and the research on the flying machine was terminated.

In order to obtain enough magic materials to make Wizard Vanguard 1, they even cut down more than half of the forests on the entire planet, and in the process of producing this material, almost two-thirds of the treemen on the entire planet died, and at that time the atmosphere on the planet was gray, in fact, the dust in the air was the death of giants

After that, the corpse ashes, and the whole planet was also plunged into a miserable world. Because of the harsh air environment, many tree people are as thin as firewood, and some tree people fall to the ground and die instantly because they can't receive enough sunlight for a long time.

Skyscrapers made of Wizard Pioneer No. 1 materials rose from the ground, and at this time, the entire world of treants showed extraordinary unity, and the unwell-behaved treants automatically gave up entering the house that could isolate the black devil, while the healthy treants lined up to enter the tall buildings one after another.

In order to prevent the Black Devil Substance from entering the tall building again, they even sealed all doors that could enter the building.

After all the healthy tree people entered the skyscraper, they thought that everything they could do had been done, and the rest was left to fate, but in the end, at the suggestion of Toka and the others, they did one last crucial thing in the skyscraper.

In order to prevent the complete destruction of the Treant race, but limited by the amount of magic materials in the skyscraper, they decided to use the Magic Nutrient Solution to preserve some samples of the Treant embryos, as well as some torsos of the Treant Elders, so that they could be left for future generations to study and leave a seed for the continuation of the Treant Race.

The Treants believe that even if everyone is doomed, they still believe that the catastrophe will pass, even if there are no living Treants left on the planet by then. But when these tall buildings collapse, the nutrient solution will flow into the soil, and the Treants can repopulate on the planet.

In fact, they didn't know how long the Treant embryos in the nutrient solution could be kept, but this was only their worst-case plan, and it was also a helpless plan. Toka objected to the preservation of his torso with a limited nutrient solution, believing that it was pointless that he was dying, but eventually part of his torso was preserved.

Most of the above holograms are first-person images of Toka, and some of them are information that he recorded in his body after hearing it with his ears.

"It's a shame for the Treants, they could have built a spaceship to escape from their home planet." Yang Yang looked at the holographic projection and sighed.

Nosmune nodded with a grimace: "Yes, I think we mermaids are lucky." ”

Oldman had a solemn face: "They did their best, the planet reset is irreversible, but it's a pity that they don't know this, otherwise they will definitely do their best to build a spaceship." However, it is also very difficult for the spaceship to find a suitable ecological planet in the vast space, and our giant race is also lucky, although Tanamu is dying, I believe that the landlord will have a way. This last sentence is estimated to make Cheng Shi feel a lot of pressure.

Barbara shook her head: "The tree people are really cute, they have no quarrel with the world, and it is really a pity that they live quietly in the woods." ”

Cheng Shi stood in place for a long time before speaking: "Xiaoqiao, the tree man race is a race of intelligent plants worthy of respect, immediately go to other similar towers to collect the biological tissues in these nutrient solutions, we must try our best to improve the data of this civilization." ”

When Cheng Shi read these hologram materials, although he was amazed to witness the process of the implementation of the planet's ecological reset program, he was also thinking about another question, the same ecological reset, why the planet was completely reset, and the mermaid planet's reset program was terminated after half of the execution. He pondered that by comparing the differences between the two planets, he might be able to discover the differences between the mermaid planet, and he would be able to solve the problem of binding himself to the mermaid planet as soon as possible.
