The four words of biological civilization were only known by Zhu Tianxing after accepting the inheritance of the Alaqi civilization. However, he always thought that biological civilization was like his own, so how could he not be surprised after hearing the queen's words?

"You mean that elves belong to biological civilization?" Zhu Tianxing couldn't believe it.

"Yes, just like the adults, but the elves belong to the plant system." The queen confirmed it again and continued: "In fact, it attracted the attention of me and the elders after the Second War between the Adults and the Byron army. Because the adults' strength has grown too fast, and the number has exceeded the ability of a Warcraft master. In the past 7,000 years, there has never been such a number of Warcraft masters on this continent. Although our elves' civilization has retreated, we have not forgotten our understanding of biological civilization. Therefore, I had doubts about the adults at that time. Through the subsequent battles, it was not until the Adults led hundreds of thousands of biological troops into the Kobra Empire that we completely affirmed your identity."

Although Zhu Tianxing knew that his number and strength of monsters would definitely arouse suspicion of humans on the continent, he never thought that there would be humans on this continent to reveal their identities. Unexpectedly, there would be another group of biological civilizations, and it was also a plant system.

"What biological civilizations do you know?" The emergence of plant-based biological civilization completely changed Zhu Tianxing's previous understanding.

"We elves are just intermediate biological civilizations, so we don't know much about these. The reason why we guessed the identity of adults is because we found the existence of life energy in your creatures." The elf queen explained.

It seems that Tina is right, and Zhu Tianxing is also attracted by the life energy in the wooden pot.

"By the way, Your Majesty, how did these pure life energy be produced?" When he mentioned the life energy, Zhu Tianxing immediately took out the wooden pot from the ring.

"These life energy is produced by the Tree of Life, but due to the environment here, the Tree of Life has completely stopped growing and has been shrinking in the past thousand years. Therefore, even the life energy output has become lower and lower." The expression on the queen's face was a little depressed, "This is also the reason why I invited the adults here this time."

"The Tree of Life relies on absorbing the energy contained in the planet and the energy generated by the sunlight for growth, and then converting the excess energy into pure life energy and storage in the energy pool. In the past, the reproduction and production of elves were all nurtured in the energy pool, but with the shrinking of the tree of life, it is difficult for the energy pool to produce new elves now, and the elves may disappear in a few thousand years."

"Then do you want me to help you?" Zhu Tianxing had already guessed the meaning of the elf queen.

"Yes, based on the increase in the number and species of adults, it can be judged that the racial civilization led by adults has not degenerated. Therefore, I hope that the masters can help our elves return to their homeland so as not to exterminate the elves." Here, the queen and all the elders stood up, walked to Zhu Tianxing, and bowed together.

"This~~" Zhu Tianxing was a little embarrassed. He had no doubt about what these elves said. After knowing that the elves also belonged to biological civilization, all the questions he had arisen were solved.

The so-called tree of life is equivalent to the breeding tower of Arachi creatures, and has the same function. The bacterial blanket is like a barrier for elves, but he is very interested in the way the tree of life absorbs energy.

According to the elves, as long as the energy is sufficient, the roots of the tree of life can even cover the entire planet, and at the same time, they can absorb star energy to convert them into life energy. If the Arachi creatures also have the same ability, the energy problem can be greatly solved.

"Your Majesty, my tribe is called Arachi Biology. As you said, although our two tribes belong to biological civilizations, they are very different. Even if I want to help, I don't know where to start." Zhu Tianxing did not want to shirk it, but to tell the truth. He really couldn't think of how to help the elves.

"How does the life energy in the adult's biological body produce?" the queen asked.

"It's this thing." Zhu Tianxing took out a piece of ore from the ring and handed it to the queen.

"Elemental Crystal?" All the elves present recognized the ore.

"Yes, on this continent, it is called elemental crystal. The energy required by our Arachi creatures is it. The life energy in the organisms is also generated from this, but I feel that the purity of its energy is far less than that of the tree of life." Zhu Tianxing explained.

The elders, including the queen, had the silicon crystal in Zhu Tianxing's hands. They felt that this was a bit incredible, because the elemental crystal is not unfamiliar with this continent, but they had never discovered that it had such a effect.

"You can try it to see if the Tree of Life can absorb it, but the elemental crystals are very rare on this continent." Zhu Tianxing's next meaning was very clear, that is, even if the Tree of Life can absorb it, it may not be able to change the current situation of the elves.

"We can test it first." The elves did not listen to Zhu Tianxing's words.

"Okay, I'll go back first. If you have anything to help, you can call me anytime." Zhu Tianxing couldn't wait to leave here, and wanted to ask Tina about the question about the Tree of Life.

He wanted to integrate this new energy use method into the Arachi biological civilization.

"Tina, do you think this method is feasible?" After leaving the ancient tree of life, Zhu Tianxing contacted Tina directly and conveyed his thoughts.

"Master, the biological civilization of the plant system has never been encountered in the previous controllers. I have not touched the method you mentioned. If you can use the genes of the Tree of Life to analyze, you may have discovered something." Tina replied immediately after hearing this.

It was not difficult to obtain the genes of the Tree of Life. Zhu Tianxing broke up a small branch on the trunk next to him and brought it to Tina.

Tina's analysis took a certain amount of time, and during this period, Zhu Tianxing did not disturb her.

"Sir, Your Majesty, please invite me." An elder came to Zhu Tianxing and said.

"How is it, can it be used?"
