When Su Xiao returned to the nest, it was still in the evolutionary stage. Looking at its appearance, it could not complete the evolution for a moment.

The success or failure of evolution can only depend on echelon itself, which is not a small risk. Once echelon fails in evolution, Su Xiao's arrangement will disappear.

It's not realistic to get the Zerg army without taking any risks. Su Xiao has long thought that he used withered species to reduce risks.

Waiting for three hours, the shrinking nest stretches out, and the spindles in the nest send out a wave of spirit. She needs energy.

The mantis beetle near the insect nest is busy. It transports the accumulated blood and meat of prey to the insect nest in three hours. The speed of devouring of the insect nest is obviously faster.

[hint: your temporary summoner, Zerg parent, has been promoted to phase 2. ]

[the nest has evolved to the second stage, and the attached ability has been improved. ]

the energy storage organization has been upgraded to the second stage, and the upper limit of energy storage has been increased to 10000 points. ]

[the oozing tissue has been upgraded to the second stage, and 150 insect eggs can be produced at one time, and the oozing speed has been increased by 12%. ]

[the incubator has been upgraded to the second stage, and 100 small and medium-sized Zerg units can be cultivated at one time. ]

[awakened new genetic memory: monitoring nests (Zerg buildings). ]

[awakened new gene memory: hunting teeth (fighting Zerg). ]

[awakened new gene memory: spore tank (transport, protect nest). ]

……

All abilities of the insect nest have been improved, and there is one more building, two kinds of Zerg arms.

Hunting teeth are used for fighting. It's not clear how effective they are. Oozing + breeding requires 60 biological energy, which is 20 points more expensive than poisonous thorns.

As for spore tank, it's logistics. It only needs 120 biological energy.

From the current situation, the ability of the two-stage nest is not strong, but it is not weak. It is enough to deal with some small tribes, at least it has self-protection ability.

Bubwang has entered a three-stage nest before. There are more than a dozen kinds of arms in that nest. If it is not that evolution can unlock a large number of gene memories, it is that there are other ways to improve the Zerg arms.

"Come out."

Su Xiao stands in front of the insect nest, trying to summon the squatting insect sister at home.

“……”

There is no sound in the insect nest. Now Jila's loyalty has reached 88. Su Xiao will not refuse most of his orders, but let her out of the insect nest.

Su Xiao pulls the acanthopanax out of the nest and looks at the struggling Acanthopanax in his hand. Su Xiao feels that the other side's body shape is obvious. Compared with human standards, the former Acanthopanax belongs to children's body shape, and now it is about the same height as primary school students.

"Ask you a few questions."

As soon as Su Xiaogang let go, Jila trotted to the entrance of the insect nest, sticking out only one head. It seems that how dangerous the outside world is. In fact, this is the instinct of the mother. The mother of the Zerg will try to protect itself and strengthen the nest.

"What's the problem."

Spinra looks around, which is the vigilance of squatting at home to the outside world.

"Where the nest stores energy, or where the energy storage organization of the nest is located."

"That's it."

Jila's hand is pressed on the insect nest, and the fingers wrapped in the shell point to the meridians on the insect nest, which means that biological energy is stored here.

"That is to say, the energy storage tissue is not a single organ in the nest, it is completely integrated with the nest?"

"Well."

Su Xiao's face was smiling when he got Zila's reply.

"What if you devour other nests?"

"Will be very happy."

Zillah nodded his head.

"No other side effects?"

"No, even if it's another mother, my nest can devour, and it can also get gene memory."

"Is that so."

Su Xiao looks at bubuwang, who has understood Su Xiao for a long time.

"I can swallow other insect nests directly. We can catch a fart beast and rob directly. How can we make money without looting?"

Baja's eyes are full of violence. He's about to vomit when he catches wild animals.

"This involves the cost. If it is a two-stage insect nest that has been developed for a long time, the force of the Zerg should be at least 100. As for the three-stage insect nest, the force of the Zerg might exceed 10000."

Su Xiao is considering which stage of the nest to start with. He directly ignores the four stages. There are three four stages of the nest in the world. Each of the four stages has more than 100000 Zerg forces, which cannot be defeated at all.

There are a lot of three-stage nests, because it is not too difficult to evolve from two-stage to three-stage. As for the evolution to four-stage, there should be very strict requirements, otherwise there will not be only three four-stage nests.

"JIRA, what is this."

Su Xiao takes out the amputee foot from the storage space. It's about 20 cm long. Its arms are thick. The fractures on both sides are uneven. Some places are very sharp. The color seems dark, but the reflection of the sun is red.

As soon as Su Xiaogang took out the black foot, Jila ran out of the insect's nest. He grabbed the black foot with two small hands and bit it.

The body of Qiba ~

Jila is frozen. She slowly looses her mouth, squats on the ground, and covers her mouth with her hand.

Su Xiao lifts his foot and kicks jianla aside. Just now, jianla is in a state of mind that is almost out of control.

"BAHA, wake her up."

"Good."

Baha'a's wings spread out, and he rushed forward to conduct "psychological counseling" for Acanthus.

A few minutes later, some dazed spine pull of lie on the ground.

"What is this?"

Su Xiao stands up and pulls his black foot forward.

"This is..."

Spinra was obviously confused. She pinched the corner of the foot with her fingers. She seemed to want to break off a small piece, but with her strength, she couldn't do it at all.

With a click, Su Xiao broke off a small piece from his foot and threw it to Jila. Who would have thought that Jila had a probe and swallowed it.

"This is the gene fragment left by the four stage fighting Zerg."

Acanthus no longer longed for the black foot, and lost interest completely.

"What's the point?"

Su Xiao looks at the armour and foot in his hand when he speaks. It should have been dealt with by the sun tribe.

"If it's complete, it can make my nest breed this kind of fighting Zerg, but it's very incomplete."

"You still have this function?"

"Well."

Spindles pulled back to the nest, Su Xiao's face was deep in thought.

"Amu, you stay here and watch. Let me know if you have any information. Bub, Baja, follow me."

Su Xiao went to the forest. He was going to attack other insect nests to capture biological energy. Now the development speed is too slow.

After about an hour's March, Su Xiao left the forest area and arrived at a wasteland where the weeds were at least half a meter high and grew intensively.

This kind of terrain shows that there are insect nests in the nearby area. Only when the wild animals are killed, can the weeds grow violently, and the Zerg is the biggest natural enemy of the wild animals.

Su Xiao walked in the grass. A large number of insects jumped out or flew away. A grasshopper like insect even jumped on Buwang's face.

Bubuwang shivered with fear. Once he flirted with the supernatural wasp, the wasp also rushed to his face, facing his nose is a needle, and the painful memory will never be forgotten.

Su Xiao's steps stopped. A nest with a height of 30 meters appeared in front of him. In terms of scale, it was a second-order nest, which had been operated for a long time.

"Bub, to locate the matrix."

Su Xiao takes out the phagocytic bullet from the storage space when he speaks. In the second stage, the nest can't carry the phagocytic bullet.
