When Su Xiao returned to the vicinity of the hive, the hive was still in the evolution stage, and it was impossible to complete the evolution for a while.

The success or failure of the evolution can only rely on the spiny pull itself, which is not a small risk, once the spiny evolution fails, then Su Xiao's arrangement will come to naught.

It is simply unrealistic to want to obtain the Zerg army without taking risks, and Su Xiao has long thought of the risk in this regard, and he used the withered seed before to reduce the risk.

After waiting for three hours, the hive stretched out in a contracted state, and the spines in the hive emitted a mental fluctuation, and she needed energy.

The mantis near the hive was busy, transporting the prey flesh accumulated in three hours to the hive, and the hive devoured significantly faster.

[Hint: Your Temporary Summon: Zerg Mother has been promoted to Stage 2.] 】

[The hive has evolved to the second stage, and the attached abilities have been increased.] 】

[The energy storage organization has been upgraded to Phase 2, and the upper limit of energy storage has been increased to 10,000 points.] 】

[The eggification tissue has been upgraded to the second stage, which can produce 150 Zerg eggs at a time, and the eggification speed is increased by 12%. 】

[The cultivation sac has been upgraded to the second stage, which can cultivate 100 small and medium-sized Zerg units at a time.] 】

[Awakened New Genetic Memory: Monitor the Lair (Zerg Building).] 】

[Awakened new genetic memory: Hunting Tooth (Combat Zerg).] 】

[Awakened new genetic memory: Spore Tank (transporting, protecting the hive). 】

……

All of the Hive's abilities have been increased, and there is also one more building, two Zerg classes.

The hunting tooth is used in battle, and it is unknown what the combat effectiveness is, and it takes 60 points of biological energy for eggification + cultivation, which is 20 points more expensive than the stinger.

As for the Spore Tank, this thing is a logistics type that only costs 120 bioenergy per piece.

Judging from the current situation, the ability of the second-stage hive is not strong, but it is not weak, it is enough to deal with some small tribes, at least it has the ability to protect itself.

Bubuwang had entered a three-stage hive before, and there were more than a dozen types of troops in that hive, if it wasn't for the three-stage evolution that could unlock a large number of genetic memories, there were other ways to improve the Zerg class.

"Come out."

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

“……”

There was no sound coming from inside the hive, and now that Thornra's loyalty had reached 88 points, it would not refuse most of Su Xiao's orders, except for letting her out of the hive.

Su Xiao pulled the spiny out of the nest, looking at the struggling spiny in his hand, Su Xiao felt that the other party's body shape was obviously good, compared with human standards, the previous spiny pulled was a child's size, and now the height is about the same as that of a primary school student.

"A few questions for you."

As soon as Su Xiao let go, Thorn La trotted to the entrance of the hive, only poking out one head, it seemed how dangerous the outside world was, in fact, this was the instinct of the mother, and the mother of the Zerg would protect herself as much as possible and grow the hive.

"What's the problem."

The spiny probe poked his head to look around, which was the vigilance of the outside world at home.

"Where does the hive store biological energy, or where does the hive's energy store tissue?"

"That's it."

Thornra's hand pressed on the hive, and the finger wrapped around the carapace tapped the meridians on the hive, meaning that the biological energy was stored in it.

"That is, the energy storage tissue is not a separate organ within the hive, it is completely integrated with the hive?"

"Hmm."

After receiving Thornra's reply, a smile appeared on Su Xiao's face.

"What if you devour other hives?"

"It will be a pleasure."

Thorn Raksha nodded knowingly.

"No other side effects?"

"No, even if it's another mother, my hive can be devoured, and I can also gain genetic memory."

"Is that so?"

Su Xiao's eyes looked at Bu Bu Wang, who had already understood what Su Xiao meant.

"Damn, we can swallow other worm nests directly, and we will catch a fart beast and go directly to rob, how can we get rich without robbing."

Baha's eyes were fierce, and he was almost vomiting when he caught the beasts.

"This involves the issue of cost, if it is a two-stage hive that has been developed for a long time, the Zerg strength is at least more than a hundred, and as for the three-stage hive, the number of Zerg troops may exceed 10,000."

Su Xiao was thinking about which stage of the hive to attack, and he directly ignored the fourth stage, there are three four-stage hives in this world, and the strength of each four-stage hive is more than hundreds of thousands, and it can't be defeated at all.

There are many third-stage worm nests, because it is not too difficult to evolve from the second stage to the third stage, as for the evolution to the fourth stage, there should be very strict requirements, otherwise there will not be only three fourth-stage worm nests.

"Acantha, what is this?"

Su Xiao took out the amputated leg from the storage space, this thing was about twenty centimeters long, the arm was thick, the fractures on both sides were uneven, some positions were very sharp, and the color seemed to be pitch black, but red light was revealed under the reflection of the sun.

As soon as Su Xiao took out the black nail foot, Thorn ran out of the insect nest, grabbed the black nail foot with two small hands, and bit it.

Click~

Thornra's body froze, and she slowly loosened her mouth, squatting on the ground, covering her mouth with her hands.

Su Xiao raised his foot and kicked Thorn to the side, and just now, Thorn La appeared in an almost uncontrollable mental state.

"Baha, help her wake up."

"Okay."

Bahá's wings spread out, and he pounced on Thornra for 'psychological counseling'.

A few minutes later, he was lying on the ground in a daze.

"What is this?"

Su Xiao pulled the black armor Adachi in front of him.

"It's ......"

Obviously confused, she pinched the corner of the nail foot with her fingers, as if she wanted to break off a small piece, but with her strength, she couldn't.

With a click, Su Xiao broke off a small piece from the nail foot and threw it to Thorn La, who would have thought that Thorn Pull would probe it, and actually swallowed it in one gulp.

"This is a fragment of the gene left behind by the four-stage battle zerg."

Acantha no longer craves black armor and loses interest completely.

"What's the effect?"

Su Xiao looked at the armor foot in his hand as he spoke, this thing should have been dealt with by the Sun Tribe.

"If it were complete, I could have allowed my hive to breed this kind of battle zerg, but it is very incomplete."

"You still have this feature?"

"Hmm."

Thorn retracted back into the hive, and Su Xiao groaned on his face.

"Eminem, you stay here and keep me informed if there is any situation, Bubu, Baha, come with me."

Su Xiao walked towards the forest, he was going to attack other insect hives in order to seize biological energy, and the current development speed was too slow.

After traveling for about an hour, Su Xiao left the forest area and arrived at a barren grassland, where the weeds were at least half a meter tall and grew densely.

This kind of terrain indicates that there are insect nests in the nearby area, and only when wild animals are killed will they cause wild grass to grow wildly, and the Zerg are the biggest natural enemies of wild animals.

Su Xiao walked in the wild grass, and a large number of insects jumped out or flew away around him, and an insect that looked like a grasshopper even jumped on Bu Buwang's face.

Bu Buwang shuddered with fright, and once it teased the supernatural hornet, the hornet also rushed to its face, and there was a tail needle at its nose, and it will never forget that painful memory.

Su Xiao's footsteps stopped, and a thirty-meter-tall insect nest appeared in front of him, judging from the scale, this was a second-order insect nest, and it was the kind that had been in operation for a long time.

"Bubu, go and determine the position of the mother."

Su Xiao took out the devouring from the storage space as he spoke, and the second-stage insect nest would definitely not be able to withstand the bullets that were devoured.
