When the PDC's envoy found Su Yu, he was in his palace in the Maosheng New District. Of course, he himself never thought of a palace, but in view of the fact that he was not a king but was more like a king, it was not an exaggeration to call the place where he lived a palace. This place is so big that even words like palace are not enough to describe it.

In the heart of the Maosheng New District, the heart of the former Tengger Desert, which was once a desert, has now become an oasis covered in green forests. In the forest that stretches for hundreds of thousands of square kilometers, there is a giant tree that is more than 2,000 meters high, and the crown of a tree covers an area of more than ten square kilometers, towering into the sky like a sharp sword, majestic, towering, like a silent giant, looking down on the forest under its feet.

At different heights in the semi-middle of this giant, it seems that several branches have grown out of purpose, and the top of each branch has no branches, but a flat area, which has been specially carved out as a tarmac for people to come and go. When the PDC's envoys came to visit Su Yu by plane, they stopped here, and then entered the palace in the trunk of the giant tree.

This tree is called the World Tree by the earthlings, and it is famous on the earth today, and several religions even worship it as a totem, believing that it is the body of the legendary mother tree. It represents a great power that can compete with the brood of the Zerg. In the forest under the roots of the World Tree, there are countless people from all over the world who have come to seek the protection of the magical power of the World Tree, and their numbers are so large that a city of considerable scale was soon formed under the tree, but none of these people had the opportunity to enter the Giant Tree Temple.

In fact, this giant tree is just a sub-tree of the mother tree on the surface of the earth, and in order to achieve certain purposes, it is only to create an impact on human society, so it deliberately makes its body so huge.

The result of this is to give the earthlings a more intuitive display of the power of the mother tree, so that when the earthlings see this, they all feel that the depths of their souls have been shocked, and they can't help but be overwhelmed by the magical power of the mother tree.

After receiving the request from the PDC from the envoy, Su Yu immediately agreed, signaling that the power of the mother tree would appear on the battlefield at the time it deemed appropriate to help humanity achieve victory, but, in the same way, Su Yu also made a request, that is, the PDC's intelligence resources wanted to be opened to him.

The two sides quickly reached an agreement on cooperation, after all, this cooperation has been carried out many times, and now the mother tree and humans are interdependent, although, with the expansion of Su Yu's power in human society, and its position is becoming more and more embarrassing, but this cooperation will definitely not be affected.

After finalizing the cooperation, Su Yu turned around to check his readiness for the war, as a system force that exists on the earth and the Federation and PDC at the same time, in fact, Su Yu also has his own preparations.

He descended from the trunk elevator directly into the body of the mother tree underground, and entered a hall filled with strange scientific research equipment that was rarely seen in human society, and countless people and goblins worked and walked through it.

The goblin here refers to a kind of creature parasitic in the body of the mother tree, that is, the kind of creature that Zhang Zhe and Yu Jing have seen in the body of the mother tree, the body length is not more than an inch, with dragonfly-like wings, but the body structure is very similar to that of humans, with facial features, limbs, everything is specific and micro, almost no different from humans, but it is a species naturally bred by the ecological environment in the mother tree.

This creature has an extremely high IQ, can live with humans, and even work, can be qualified for the role of an assistant to human experimental work, and survives in the internal environment of the mother tree, he has some advantages that humans do not have.

In fact, where Su Yu is now located is the new Institute of Biological Sciences, which has gathered almost the vast majority of the best scientists on the planet. However, the content of the current research institute of biological sciences has far surpassed the scientific system of human biology, and it has made a big step forward in the direction of biological civilization.

Using the various conveniences provided by the mother tree: the magical substances of some ontologies of the mother tree for research, as well as the scientific research conditions created by the mother tree that human beings cannot have, the scientists here have been extremely nervous in biological science, and even crossed the limit of the former geobiology, and developed biological science into an all-encompassing and promising future, which can almost support the development of human interstellar civilization in the future A complete scientific system.

"Spore Cannon, how's the preparation?"

Su Yu asked Zhang Changlingdao, a former academician of the Academy of Engineering who was a distinguished expert of the Ministry of Agriculture of the People's Republic of China, and now, the former leader of the investigation team, a first-class biological expert in Huaxia Province, has thrown himself into the arms of the Maosheng Academy of Biological Sciences, and is responsible for the research of the military application of biological sciences in the Academy of Biological Sciences.

Su Yuwen's spore cannon is a weapon researched by Zhang Changling to imitate the earth-shattering cannon issued by the mother tree in the war, using a special surname of the mother tree's ontology substance, which is particularly effective in dealing with the Zerg, and has shown its might many times in previous wars.

Zhang Changling turned his head and replied: "Hundreds have been bred, and they are being prepared in the gestation cavity and ready to be launched at any time." ”

This answer made Su Yu very satisfied, "Well, it's good!" Su Yu asked again, "What are the types?" ”

Zhang Changling replied: "There are mainly space plankton and fungi, and as far as we can see the information we have so far, they have the strongest lethality to the Zerg. Of course, these two also have disadvantages, that is, they lack sufficient intelligence, which makes it difficult for us to continue to expand the war advantage, and we can only repel the enemy's attack. In order to cultivate higher intelligences and achieve stronger tactical objectives, we need more time to breed newer species. ”

Oh! Su Yu nodded, with some regret in his voice,

"But this time, we probably need a certain amount of space combat capabilities! The PDC's space fleet is likely to attack, and I hope we can provide them with enough protection - even if they lose the battle, they can't lose too much, and try to save as many people as possible, these are the elite seeds of the human race on Earth, and after a while, they are likely to play the role of the main beam of the Grand Fleet. ”

Zhang Changling is also the first batch of people to accept the transformation of the mother tree on a large scale, and his body has long been different, but the human complex in his heart still makes him very concerned about human beings, as soon as he heard Su Yu's words, he immediately frowned, pondered for a while and said:

"Oh well! I'll try again and try to find something that works. ”

"Well, that's good, then I'll leave it to you," Su Yu praised Zhang Changling, "I will let Professor Liao Yunsheng cooperate well with you." ”

"Huh! That's the best," Zhang Changling immediately cracked his mouth and laughed, "On his side, there are some good things, and I have always been greedy for them." I'm sure I'll be able to do something new. ”

Su Yu, continue to walk, check the situation one by one in the various departments of the Underground Biological Science Academy, now he is not just a businessman, in his hands, in addition to the mother tree, he also has a force with quite strong combat ability.
