Returning to the surface, Chen Mulin didn't dare to stay longer for a moment, and drove the armored combat vehicle to pull the transport vehicle and slip away.

After nearly a week and thousands of kilometers of detours, he finally returned to the base.

At this time, he relaxed a little and uploaded the photos taken at the risk of death to the live broadcast room.

He said in a dull voice: "I came back and found a big guy down there, scared me half to death, but fortunately I ran fast!"

After reading the pictures, the barrage began to be restless.

[Barrage: Wow, there is a cockroach nest under the feelings!]

[Barrage: That big guy is probably the worm mother.] 】

[Barrage: This is a hornet's nest, the Martians didn't find out, but they provoked a group of big cockroaches. 】

[Barrage: How good the food must be to grow such a big cockroach.] 】

[Barrage: It looks terrifying.] 】

[Barrage: It's still a green liquid, it's disgusting!]

……

"That's right, such a big cockroach, with the firepower of Ma Krypton One, I have to retreat strategically first, hoping that their army will not be killed here, otherwise it will be troublesome. ”

Chen Mulin calmed his face, touched his chin and analyzed: "Now I have provoked this group of cockroaches, and it is only twice, it is estimated that it has been remembered, and it is difficult to get rid of their entanglement in a short time." ”

"What should I do?"

Chen Mulin desperately grabbed his head, very irritable.

Being worried about such a group of cockroaches, let alone going out for a walk, I don't even feel safe staying in the base.

For this question, the proposal of the water friend is like this.

[Barrage: Build a bunch of weapons and fight them to the death!]

"No!" Chen Mulin shook his head and rejected the proposal: "With my current attack ability, it's okay to deal with some cockroaches of average size, but if it is the size of those trucks, it is estimated that it will take some time, and there is no way to kill them in large quantities, there are too many of them!"

"Besides, you all said that the biggest one is the insect mother, and the cockroach has a strong reproductive ability, and the reproduction ability of such a big one is not against the sky, and it can't be killed!"

[Barrage: Then kill the worm mother.] 】

"Mother insecticide may work, but how?"

Chen Mulin thought about it, and there is indeed only one way to solve the problem.

It is possible to determine which cockroaches have their own way of communicating over long distances, like a network connected together, and the mother worm is their host and can give orders to all the cockroaches.

Naturally, the mother worm may have known about it when she provoked them for the first time, otherwise she would not have chased them after her until she reached the vicinity of the base.

In fact, it is not difficult to see that they can already guess an approximate idea as far as they can organize reconnaissance.

If the mother worm is killed, their communication network will completely collapse, and they will turn from a group to an independent group, and they may still be in groups of threes and twos, but there will never be a large group at the same time.

There is also a possibility, that is, those cockroaches, which are second only to the mother worm, divide up the whole group, form a small group of forces, and fight each other.

In any case, there is absolutely no harm in killing the mother worm.

But herein lies the problem, how to kill the mother worm?

With the size of the Mother Worm and the guards beside her, if you want to kill the Mother Worm, you must have weapons of mass destruction, and you must have enough power to break through its defenses.

At present, primary laser weapons do not have such great power at all, unless the caliber is increased by dozens of times.

However, relatively, the caliber has increased, and the energy consumption will also increase, now there are many energy crystals, the key is the problem of energy output, the primary laser weapon can not output such a huge amount of energy at the same time, if it can output such a large amount of energy, it does not need such a large caliber, it is the technology of a more advanced weapon.

"Oh, there's that!"

Suddenly, Chen Mulin remembered a forgotten weapon, a grenade bullet!

It was just an ordinary fragmentation grenade, at the beginning of the period, because it was too ordinary, Chen Mulin didn't care much about it, and he didn't make it, and he just saw it at the first glance and put it into the cold palace.

Also, with such an advanced weapon as a laser gun, who would look up to an ordinary fragmentation grenade?

Now think about it, killing large-volume creatures, compared to laser guns, or grenades are more practical, one grenade is not powerful enough, then come two more, if it is not enough, then pack a bundle, it can definitely blow up the worm mother!

……

Over the next few days, Chen began to produce hoarding grenades, while going out on patrol every day, up from twice a day some time ago, to once every hour.

However, he discovered a very strange phenomenon.

On the first day, he was able to find a few cockroaches on each patrol, but in the next few days, he found that the cockroaches were all gone, and the few that he occasionally found were retreating.

If Chen Mulin had been very happy some time ago, he would have finally been able to feel at ease.

However, he was not happy now, and he had a faint feeling of uneasiness, always feeling that something was wrong.

It's so calm, like the feeling that a storm is coming.
