Xiao Yu brought Xiao Bai and Li Sisi to the dense jungle where the ruins were hidden. Most of the monsters in the woods were level 2 and level 4 monsters were very rare. Not to mention that Xiao Yu even Xiao Bai, who had the weakest combat power, could deal with them. These monsters felt the aura of Xiao Yu, and had already escaped ten miles away and dared not show up. The three of them came to the ruins without any obstacles.

The forests on the periphery were blocked by the people of Wentian City, and all except those responsible for excavating the remains were forbidden. The mechanical remains did not change much, with dust and vines covered with dilapidated appearance. There were several temporary excavation sites established by research institutes around the remains. Xiao Yu and his men passed by one place. The place was not big, about half a football field, with two hundred soldiers guarding them, and more than a dozen foxes were busy around a magic tank that had just been moved out of the remains. Their task was to check the degree of damage of various parts of the chariot and keep a record. If the damage was not too serious, it would be sent to the machinery factory for repair, transformed into a chariot and put into use. If the damage was too serious, it would be inconvenient to repair or the repair cost was too high, the fox girls would tear it off and only pick some intact parts and send it back.

Xiaobai introduced: "Since the institute received the excavation of the remains, the robots have excavated a total of 30,000 units, which can be repaired no more than 7,000. The magic tanks have taken away 69 units, and only ten have been transformed and simplified, and have been put into use again. As for the airships in the remains, there are not many. Our technology is not enough, so we cannot repair airships at present. Recently, we have been greatly inspired by the research of the airships of the Goblin tribe and have recently started to be put into use."

Xiao Yu asked: "How much has you achieved in the development of the ruins?"

Xiaobai replied: "At present, less than 5% of the time, there are many warehouses in the machinery factory, and there are nearly 10,000 robots in each warehouse. The total number of robots we excavated is only more than 30,000, so the remains can be developed for a long time."

Xiao Yu nodded: "The speed is not slow anymore. After we subdue the spacecraft, we will remove the guards in the ruins. At that time, we will no longer be cautious when digging. The speed should be much higher. Okay, hurry up and let's go."

The three of them walked towards the ruins.

At this time, accompanied by an eagle, a dragon eagle beast with two heads flew out of the woods, hovering at high speed and making a sharp sound. Ordinary dragon eagle beasts will not grow two heads, but there are people from the sub-gods here, and it is not uncommon to have strange creatures appear. The dragon eagle beast seemed unable to distinguish the strength of the other party, and dived down to attack Xiao Yu and the other two.

Xiao Yu looked at it disdainfully: "It's just the strength of the early stage of the fourth level."

A silk thread also appeared on Li Sisi's fingertips, ready to launch an attack.

Xiaobai's eyes turned and stood up and said, "Master, let me do it." As he said that, he opened his eyes wide and stared at the main Dragon Eagle Beast. Xiao Yu felt a spiritual force emanating from Xiaobai. When the Dragon Eagle Beast flew less than fifty meters, he suddenly stopped in the air, turned a corner, and landed gently beside Xiaobai.

Xiao Yu didn't expect that after two months of experience, the little fox's charming technique became so powerful.

Xiaobai did not kill the Dragon Eagle Beast, took out an injection and pierced heavily into the Dragon Eagle's neck. A glowing dark green liquid squeezed into the Dragon Eagle Beast's body. The Dragon Eagle Beast was wailing in pain, and fell to the ground and twitched violently. His feathers fell one by one, his muscles expanded rapidly, and his bones grew wildly. From a dragon Eagle Beast with wings five meters wide spread, he turned into a huge monster with flesh wings and could reach ten meters after it was spread. Its breath was growing, and in just a few minutes it grew from the early stage of the fourth level to the middle stage of the fourth level, to the late stage of the fourth level, and finally stayed at the peak of the fourth level!

It looks more like a skinned flying dragon.

"roar!"

The two-headed monster opened its mouth and squirted out a flame, burning the ground into a big pit.

Xiaobai pointed his hand in front and said, "Go!"

The two-headed monster roared and rushed forward suddenly. The three of them followed closely behind. The two-headed monster had too much motivation and immediately alarmed several Destroyer robots, and they were hit by two cannons and splattered flesh and blood. But an incredible scene appeared. The destroyed part of the two-headed monster quickly regenerated, and a flame was sprayed out of the Destroyer, instantly burning through the Destroyer's shield, melting half of the Destroyer's body.

Li Sisi was so surprised that she couldn't speak. She had a first-level fourth-level strength jumped to level three consecutively, becoming the peak of level four. The improvement during this period was not a little bit. Many aliens had been stuck at one level for a lifetime and could not make it difficult for Xiaobai to make a dragon eagle jumped to level three consecutively. How could this make those human feelings be suffocated?

Xiao Yu knew Xiaobai’s thoughts, and the little fox was showing off his research results to his master!

Xiaobai smiled and said proudly: "We spent a lot of effort to finally crack a small section of the sub-god super memory crystal and create several biological weapons. This is just one of them. It is still in the prototype, a bit unstable and needs to be improved, but it will be used in actual combat soon."

Xiao Yu was very surprised: "What kind of biological weapon is this?"

"I injected a magic virus called the 'Magic Crystal Killer' into the Dragon Eagle. This virus is only useful for monsters with magic crystals, and of course it is also effective for dragon monsters and dragons with dragons. The magic virus will quickly enter the magic crystal, absorb the power of the magic crystals madly and release them, causing the monster to go crazy and twist into monsters. The magic crystal is the source of the power of the monster, which stores the most rooted power of the monster. When it burns out, it is when the monster dies."

Xiao Yu didn't expect Xiaobai to crack some of the biotechnical technologies of the sub-god clan so quickly and develop such powerful biological weapons. He quickly asked: "What other weapons do you have?"

"I didn't bring you with me, so it's hard to introduce you." Xiaobai deliberately kept it a secret, which made people's appetites and thoughtfulness: "When I return to the city, I will introduce you to the master slowly!"

Although the twisted and crazy two-headed monster had a creepy regeneration ability, it was quickly bombarded into meat under the siege of the Destroyer. The Destroyer wandered around for a while, and no longer found the targets to attack, and each turned into a ball and rolled away.

Xiaobai walked between the minced meat, pulled out a long knife, searched through the bloody internal organs, and picked up a magic crystal slightly larger than his fist. The inside of this magic crystal was empty and some dark green liquid flowed. These magic viruses could be recycled through this method!

The dark green liquid flowing in the magic crystal is at least four times more than that of Xiaobai injected into the dragon eagle's body. Not only can the virus be recycled, it will not become less and less with the use, but will use more and more and more and more and more.

"Well, yes, it's not bad!" Xiaobai looked at the Magic Crystal for a while, "This 'Demon Crystal Killer' virus has grown again, and it can probably deal with the middle-level monsters in the fourth-level mid-stage."

Li Sisi exclaimed: "The virus continues to split and evolve. Wouldn't it be a monster that can destroy the world with just one piece?"

Xiaobai shook his head and said, "No, any life in the world has its limitations. The new "magic crystal killer" virus can only deal with third-level monsters. Through continuous division and evolution, they will become more and more powerful. The vitality of the virus comes from the magic power injected during production. When the power in the virus is exhausted, the virus will lose its vitality and cannot infect any creatures anymore. The "magic crystal killer" we made will split and reproduce fifty times and will die. The 50th generation

The 'Demon Crystal Killer' is the strongest, which can infect the peak of the fourth-level flying dragon. It has the power to compete with half of the dragon in a very short time!" Xiaobai sighed and said, "Oh, our technology is too different. The prototype virus of the 'Demon Crystal Killer' made by the sub-god clan back then can reproduce 600 times! The ultimate 'Demon Crystal Killer' of six hundred generations is said to allow the Dragon King to drink a good pot. Even if he cannot kill the Dragon King, it can seriously damage his vitality and it will be difficult to recover his strength for a thousand years."

Li Sisi felt creepy: "What a terrible thing."

The magical biotechnology left over from the sub-god clan is really not a good deal. Xiao Yu is increasingly looking forward to the research institute. The technology of the goblin tribe is definitely far inferior to that of the sub-god clan. The research institute has the most advanced biosynthesis technology data of the sub-god clan, and the field of synthetic biology must have great achievements. As for the amount of biological weapons, biological armor, etc., it is a kind of knowledge of the same category, and it can be mentioned, even if there is only a small part, which is enough to enable the research institute to achieve great results. Xiaobai may develop biological weapons that are more powerful than the magic cells on Jin Kui in the future!

The three of them walked towards the center of the ruins, alarming some robots on the way. Li Sisi moved his fingers, and the blue energy wire emitted out, instantly controlling the robots, one by one, and when several people walked to the pyramid-shaped spacecraft, Li Sisi's puppet silk had controlled more than two hundred robots, including more than 30 destroyers, and there was no difficulty.

More than thirty destroyers fired at the same time, and weaker fifth-level early stage players must avoid it. The puppet silk consumes very little mental power, but it is enough to control the robot steadily. Ordinary machinery belongs to the puppet tribe. No matter how powerful the puppets are, they have a characteristic: they have no spirit, no soul, and no thinking. They are originally a bunch of materials and do not have the strength. All power is fixed or sealed in the body during the production process, and they cannot resist Li Sisi's puppet silk.

According to Li Sisi's current mental strength, it is fine to control three or four hundred units. After reaching the fifth level of strength, he might be able to control a mechanical legion! Control thousands of Destroyer robots to fire at the same time, and the dragon can instantly break into slag.

Xiao Yu was attracted by Li Sisi's talent characteristics, so he was ready to train him well.

When Xiaobai saw the pyramid spacecraft, he couldn't help but rub his hands and said, "The sub-god clan is a great nation that dares to fight against the laws of heaven and earth. The high-end spacecraft they produce are not worth many valuable things! It is not enough to have a synthetic intelligent spiritual body in the spacecraft. This spirit has the ability to think. As long as it enters a certain range, this spiritual body will wake up and take self-defense measures. It is probably not that easy for us to seize the spacecraft."

"Don't worry, I have a way."

As he said that, Xiao Yu walked towards the spaceship alone.
