This is a very small mecha modification factory, the total area is estimated to be less than 1,000 square meters, after entering is a large courtyard, and then, around the yard are some modification equipment, visual inspection can see that the modification factory has three disassembled mecha standing in the modification position.

The tuning factory was obviously attacked by ironclad cockroaches, and the door was open, and there were some shoes and clothes and pools of blood everywhere, and it was clear that these were all the workers who had died in the mecha tuning factory.

Ironclad cockroach!

Zhou Sen, who was standing at the door and observing, froze suddenly, because he saw an iron-armored cockroach crawling along the modification workshop little by little.

What is it doing?

Zhou Sen obviously felt that the ironclad giant cockroach was searching.

Is there still a survivor in this tuning plant?

Zhou Sen wore a sheet and walked along the wall little by little, getting closer to the iron-armored cockroach that was hunting.

The ironclad cockroach stopped under a mecha that had been dismantled, and its body leaned forward slightly, it seemed that it wanted to climb up, however, the shelves around the mecha were fully automatic, and only when it was assembled and repaired, the shelves on both sides would be closed as needed.

Theoretically, it is very difficult for an ironclad cockroach to climb up to a twelve-meter mecha, but it is not difficult now, because the smooth outer armor of the mecha has been disassembled, revealing the dragon skeleton inside, which is easy for an ironclad cockroach with strong limbs to climb up.

Really!

The ironclad cockroach began to climb.

Could it be that there is someone in the cockpit?

Zhou Sen stared at the mecha cockpit, the door of the cockpit had been dismantled, and the cockpit was dark and gloomy, and he couldn't see anything at all.

There must be someone!

The ironclad cockroach will never climb on top of the mecha for no reason.

Zhou Sen no longer hesitated, pulled out the Tang knife, and quietly approached the left side of the iron-armored giant cockroach. At this time, the huge body of the ironclad cockroach was already attached to the mechanical legs of the mecha, and the two forelimbs were hung on the dragon skeleton of the mecha.

Now or never!

Zhou Sen did not hesitate, and rushed over with an arrow step, and the tip of the Tang knife's perfect forty-five-degree angle was directly inserted into the left rib of the iron-armored giant cockroach.

The shape of the ironclad cockroach is a combination of an ant cockroach and a praying mantis, but its body structure is close to that of a soft-shelled turtle, with a solid exoskeleton up and down, invulnerable, but there is a slit on each side of it, mainly wings and limb growth parts.

Zhou Sen's Tang knife stabbed into the back of the neck, and then, holding the handle of the knife with both hands, it slammed it fiercely, and the sharp blade directly cut the soft tissue behind the neck of the iron-armored cockroach, and then, all the way up, it was like a bamboo, and directly cut a wound of more than thirty centimeters on the neck of the iron-armored cockroach.

'Hiss-hiss......"

Zhou Sen was almost close to the iron-armored cockroach when he attacked, and the iron-armored cockroach was fatally stabbed in the neck without noticing it, making a heart-rending scream, and the body that was originally clinging to the mecha also fell to the ground, twitching on the ground with six feet facing the sky, and completely lost his breath in a few strokes.

Seeing that the iron-armored giant cockroach completely lost its breath without any reaction, Zhou Sen couldn't help but let out a long sigh of relief. Now Zhou Sen has no force value, and Tang Dao is not suitable for fighting a behemoth like the ironclad cockroach, if the ironclad cockroach is dying and struggling, it will be a big trouble for him.

A one-hit kill is the best ending.

Of course, Zhou Sen used the Tang knife to attack the back of the neck of the iron-armored giant cockroach and cut it forward, also to verify the previous dissection results. As it turned out, his previous autopsy had come to the right conclusion, the position behind the neck of the ironclad cockroach was a lethal position, and it could be easily killed.

According to the results of the anatomy, it is possible to directly attack the neck position of the ironclad cockroach, however, this position is protected by an exoskeleton and there is only one gap, and it is easy to make a mistake by directly attacking this part, but if the position between the attack neck and the wings is cut to the neck position, it will be much easier, because the soft body part exposed to the outside at that position is larger, which can ensure the success rate......

……

As the ironclad cockroach's convulsions ended, the mech modification factory, which was shrouded in darkness, fell into a moment of extreme silence.

No!

It's not quiet.

Zhou Sen heard the sound of big gasps of breathing and a frantic heartbeat.

"I've killed the ironclad cockroach, you can come down." Zhou Sen said to the dark cockpit of the mecha.

No one answered.

The sound of the big breath was gone, and it was clear that the person hiding in the cockpit of the mech was holding his breath.

"I'll give you a minute to think about it, and if you don't come down, I'll leave. Also, I need to tell you that the entire city of Gore has fallen, and there are countless planets in the five star fields that have broken out with the ironclad giant cockroach plague, so Gore Star can't wait for the rescue army. I'm starting to time it, one, two......"

"I'll come down." A somewhat immature voice rang out.

"Be careful."

With a clattering sound of climbing, a black figure came out of the cockpit of the mecha and climbed down the dragon skeleton of the mecha to the ground.

It's a teenager. With the starlight, Zhou Sen found that the black shadow was a thin teenager in overalls.

"Can you close that iron door?" Zhou Sen didn't ask any other nonsense, because, now the top priority is to make this mecha modification factory safe, even if it is temporary.

"Yes."

The teenager was in a very bad state, the whole person was in a trance, and he was staggering when he walked, presumably frightened.

The boy was familiar with the factory, and although the big iron door had lost power, he still easily closed the iron door. After closing the iron door, Zhou Sen and the boy breathed a sigh of relief at the same time.

The iron door is closed, which means that this mecha modification factory has an extra layer of security, at least, those ironclad cockroaches can't drive straight in.

Ironclad cockroaches will only actively destroy these gates when a wave of insects is formed, and under normal circumstances, a single ironclad cockroach is more like an opportunistic poacher, and they are more inclined to attack quietly than hunt with great fanfare.

Zhou Sen asked the boy to find some food and drink in the modification factory.

The boy was very familiar with the tuning factory and soon found food, which he was obviously hungry and devoured when he found it.

After the young man slowed down the pace of eating and drinking, Zhou Sen roughly understood the situation.

When the ironclad cockroach disaster broke out, a group of ironclad cockroaches poured into the modification factory to hunt humans, and suddenly, the workers of the modification factory did not have time to organize an effective resistance, so they became the food of the ironclad cockroaches, and at this time, the boy was repairing the light road in the mecha cockpit, and he hid in the mecha cockpit and witnessed the whole tragedy.

After that, the ironclad cockroaches gradually dispersed, but the boy still didn't dare to come down easily, because there would always be sporadic ironclad cockroaches entering the mecha modification factory.

It wasn't until dark that the boy waited for an opportunity to come down, but when he was about to leave the modification factory, he found that an ironclad cockroach appeared in the distance, and he quickly climbed into the mecha cockpit to hide, and this time, his luck was not good, the ironclad cockroach chased into the mecha modification factory and prepared to climb onto the mecha.

Of course, the boy's luck was good in the end, because Zhou Sen came.
