After genetic bonding, the name of this boss-level stinger was also changed to the earthly stinger.

The increase in the attributes of the earthly stinging insect was expected by him, it was already a leader-level existence, and its strength was beyond doubt.

However, what surprised him more was the skills of the earthly stinging insects, and the first two were fine.

In particular, the third passive skill, 90 high poison resistance, and more importantly, it can be immune to your own poison.

This is very interesting, when the swarm attacks, it will be more or less contaminated with your own venom, causing inevitable attrition.

If they are immune to their own poison, then the damage will be reduced by one layer when the insect tide attacks.

In this way, all the stingers must be transformed into earthly stingers as soon as possible, not just to improve their attributes.

"System, can this gene be combined with other troops?"

Su Bai tried to ask the system.

I waited quietly for more than ten seconds.

[Yes, the success rate is relatively low, it is recommended to upgrade to the brood level and try again.] 】

When I learned that I could combine, my thinking became clear.

As for the brood promotion, Su Bai currently has [Biological Core: 8/14]

Today, I got seven more creature cores, and if I'm lucky, the brood will be able to be promoted to the fourth rank tomorrow.

At this moment, the Zerg who were resting seemed to feel something and woke up and stared in the same direction.

Seeing this anomaly, Su Bai checked the topographic map and found that a group of small red dots were coming in his direction.

And look at the distance is about to reach the street outside the building.

"Fog grass? Sneak attack on the big night? ”

As time has been delayed, there have been more and more mutations, and there are not a few night raids like this.

Fortunately, Su Bai exploded another round of soldiers today, and there is now a stinging insect elite *7314

Since the swarm is dominated by stinging insects, it has been growing in size.

And the goal is to explode 100,000 soldiers, and only the stinger elite has to come out to have the capital to occupy the city.

Ordering all the Zerg to prepare to meet the enemy, the poisonous wyverns in the sky scattered and lined up, ready to attack.

All the Titan beetles also began to warm up and recharge, and the first wave of stinging bugs began to flood the streets, and with it came a fungus blanket.

Su Bai walked among the swarms, wanting to see what kind of strange beasts were coming.

He is not afraid of numbers, he is a zerg...... Top dog!!

Who can compare with the predatory races in the universe?

Then Su Bai saw several half-human-tall rats eating his kebabs in the building.

“？”

Su Bai was stunned, this was a kebab cooked by the top master Su Bai, and he hadn't finished it yet!!

Now that this delicacy has been spoiled by a few mice, can Su Bai bear it?

"QNMD stinky rat, give labor and management a life!"

The rat that was eating meat also noticed the movement outside.

Seeing Su Bai standing outside, and seeing the large number of insect nests, his eyes rolled slightly, and he immediately rushed to his large army.

"Nima! Fire! ”

Su Bai commanded several Titan beetles to fire at the fleeing rats over there.

Several electromagnetic cannons hit the fleeing rats, and the huge energy scorched the fur on the surface of the rats.

This time, its speed not only did not decrease, but increased, and at this time, the sting insect swarm also encountered the rushing rat swarm.

Basically, all of them are the size of a domestic cat.

Led by a huge rat king, half of his yellow front teeth was missing, and his fierce eyes were staring at Su Bai in the swarm at the moment.

Although it wonders why it still needs the existence of humans, there must be something extraordinary about surviving, and the other party is also leading a fierce beast.

The leader of the earthly thorn worm came to the way of the team, looking at the rat king not far away, under the moonlight, the scale armor was shining, very bright.

It buzzed, its tail hook erected, and the swarm of insects behind it buzzed, ready.

The Rat King looked at the earthly stinging insect with his eyes and then looked at Su Bai, and for a while he couldn't figure out who was the core.

In an instant, I saw twelve poisonous stingers shot out from the tail hook, and this mutation made the rat king unable to dodge and hit a few shots in time.

Then both sides launched a charge. The scene was chaotic for a while.

Su Bai ordered the Titan Beetle to bombard the mutant rats behind, and as for the poisonous wyvern, forget it.

They're on the lookout for any other beasts coming here.

After the insect tide and the rat tide fought against each other, the judgment was made.

There is a fungus blanket in your own hive, plus there are a large number of them, just a few thousand mutant mice.

Many of the rats had no time to avoid the brutal tail hook cut, and there were also clouds of venom sprayed on the rats.

This group of rats is retreating one after another, and the rat king can't sit still when he sees this scene, and is ready to go into battle in person, but the earthly stinging insects will not give him a chance.

A leap plunges into the rat pile and confronts the rat king, and the rats around him try to surround him, but the rush of insects makes them unable to pull away.

Su Bai naturally saw the actions of the earthly stinging insects, and felt quite magical, worthy of being a leader-level insect, and already had the ability to think independently.

The rat king was still numb at the moment when he was stung by the venom, and he could only try his best to avoid the tail hook, and even then he still had many wounds.

And because it was active, the toxin quickly spread through the bloodstream to all parts of its body, and soon it was paralyzed to the ground and fell silent.

The mutant rats only relied on their numerical superiority to achieve an overwhelming victory, and the strength of the monomer was not high.

It can be combined with the rat tide in the original world, the medieval rat tide, and the Black Death brought by rats, with countless deaths and injuries.

It can be seen that the rat tide is amazingly destructive, and it is also a good hand in spreading the plague.

It's a pity that Su Bai is leading the Zerg, and compared with the Zerg, the mutant rat group is still a little inadequate.

Without the support of the rat king, the rat colony soon fell apart and was swallowed up in the insect tide.

This battle can be said to be an overwhelming victory, and Su Bai only lost dozens of stinging insects, which can be regarded as a breath of relief.

Drag these insect tides back to the mother nest and devour them, and Su Bai will be able to obtain a lot of biological energy at that time.

For bioenergy, Su Bai will never have too much.

Now it is the transformation of the stinging insect swarm, and there are more than 7,200 stinging insects in total, which is estimated to be one night and one morning.

However, there are still three hours left before the exploding booster card expires, and this conversion is also counted as exploding, and the estimated time can be a little earlier.

[Release Stronghold Mission: Please clear all dangers in the city within a week, and at the same time reach the size of the swarm of 50,000 stingers, rewarding stronghold defensive troops.] 】

[Please note: If you complete the task within the time limit, there will be no reward.] 】

[Owning a city's stronghold is the first step to dominating this planet, please take it seriously.] 】

When Su Bai was about to go back to rest, the system released the stronghold task at this moment.
