What surprised Yin Jun and Chu Ming so much was Shu Xiao, who was standing at the door of the conference room with a smile on her face.

Being watched by dozens of people, Shu Xiao didn't feel any discomfort and simply went straight to the point: "Before the boss fell asleep, just in case, he and I upgraded the technology of Sentinels, Jintai, and Liuyin.

Among them, the upgraded Jintai and Liuyin Weapons can obtain a 25% increase in all attributes in all aspects.

Although the two types of mechanical weapons are still of the same generation, they are enough to defeat the third-level evolved zombies in a single fight. I can’t say how much results can be achieved. There is no problem in holding back the third-level evolved zombies.”

Hearing this, the tense faces of everyone present quickly relaxed. Chu Ming even laughed and patted Shu Xiao on the shoulder: "Hahaha, thanks to you and the boss! Otherwise we would have to pay huge casualties to complete the mission."

They don't ask for too much. As long as they can hold back the group of level 3 evolved zombies, they can guarantee victory with a small number of casualties.

While Chu Ming was happy, he didn't forget to ask: "Brother Shu Xiao, how did the sentry upgrade?"

"The main reason why I came here is this matter. The second generation of Sentinels has been developed. Now please recall all Sentinels for iterative updates."

Shu Xiao pushed up the auxiliary computing glasses on the bridge of her nose and continued to speak.

"The attributes of the second-generation Sentinel are approximately 75% greater than those of the first-generation Sentinel, and the appearance has been slightly adjusted.

In addition, the second-generation Sentinel is equipped with titanium steel alloy block armor, which doubles its anti-strike capability, and its body toughness is also greatly improved due to the optimization of mechanical architecture technology.

After this iteration is updated, the Sentinels will be able to face T2 and S2 alone in terms of combat power, and when they reach a certain number, they can quickly surround and kill level 3 evolved zombies."

A stream of data flashed through Yinjun's eyes, and he quickly read the information on the second-generation sentinels, with a hint of surprise on his projected expression.

Shu Xiao also stepped aside at this moment.

Then a burst of slight footsteps gradually came from outside the door, and Chu Ming and the officers who looked curiously widened their eyes.

If you guessed correctly, the person who walked in was the second-generation Sentinel.

But the look of this sentinel is completely different from the previous generation.

If you can still see the strong Blue Star industrial style and clear mechanical structure on the first-generation Sentinel, then the second-generation Sentinel is like a robot from the future.

It is also a humanoid mechanical warrior, its height and shape have not changed at all, except that no industrial structure can be seen on its body.

The body surface is covered with a layer of bright silver and extremely smooth armor, with a large number of nano-anti-impact layers attached to it.

There is no electronic eye visible at the head position, it is smooth.

"That's nice...what is that?"

Chu Ming pointed to a large alloy rectangular object next to the sword behind the second-generation sentry.

Shu Xiao smiled and said: "That is a semi-Gauss automatic rifle. Although it is large, it is very powerful. It can severely damage a T2 with a few shots. It is a long-range weapon that I specially prepared for the sentries."

Chu Ming's eyes suddenly lit up. The appearance of the second-generation sentry was simply the biggest surprise. In comparison, the upgrades of the other two types of mechanical soldiers did not seem so exciting.

With the number of sentries, as long as they can all be updated before the start of the plan for St City, he can have more tactical arrangements and offensive arrangements.

Some plans that were abandoned due to concerns about a large number of casualties seemed to be possible after the emergence of the second-generation Sentinel.

Chu Ming looked at Yin Jun with excitement.

"No problem, I will recall all sentries immediately and start the upgrade work immediately."

The latter said without hesitation.

Looking at the conference room where the atmosphere was relaxed and pleasant, Shu Xiao smiled lightly and exited the conference room, heading towards the research floor.

The two weapons and equipment that Chu Ming asked him for are not yet completed, and he needs to continue to go back and improve them.

The mission given to him by Shu You was to explore the limits of science, and he always felt very happy while doing research.

I have to say, this really fits the personality of a technology geek.

…

While Chu Ming and others were excited about the upgrade of three high-level weapons, great changes also took place in St City.

Before ordinary zombies woke up, a large group of corpses appeared in St City in the cold winter!

Hundreds of huge T3s and a similar number of S3s moved toward the city center. The number of second-level evolved zombies was even larger. At a glance, you could probably see no less than tens of thousands of second-level evolved zombies.

Among them, you can see some huge, long-armed, hunchbacked zombies, with a faint dark green light emitting from their backs.

Judging from the emptiness around it, it seems that no evolved zombie dares to stay around.

You don’t need to think about it to know that this is an extremely terrifying evolved zombie, and its status among zombies is higher than that of T-type and S-type evolved zombies!

"Roar!"

One of them had a hunched body and a mysterious zombie that was more than three meters tall and raised its head. Its terrifying face looked like a distorted face of an old man, with its mouth occupying almost half of the entire face!

A trace of green liquid slowly flowed out from its mouth, dripping onto the asphalt road and making a hissing sound.

The hard asphalt road was quickly corroded, creating a fist-sized pothole!

And that’s just the damage caused by a drop from the corner of this terrifying zombie’s mouth!

The zombie roared loudly, as if the back of the hump squirmed, and then split open instantly!

A dark green liquid ball with a diameter of more than one meter flew out at high speed and instantly hit an intact 100-meter-high building.

A large amount of green mist spread rapidly, and a numbing distortion sound came from the mist. After a while, the building broke and collapsed from the hit part!

Looking carefully, the alloy frame used to strengthen the toughness of the building is also 'melted' by the green corrosive liquid!

Although it is only a civilian alloy, it is still a hard metal!

Whoosh!

At this moment, a black shadow flashed out of the green mist at high speed, approaching the corrosive zombie at a speed far exceeding that of S3.

Then behead him instantly!

That's right, no accidents happened.

Kill with one blow!

The black shadow gradually emerged, and what people didn't expect was that the black shadow attacking the zombies turned out to be a zombie with long and narrow limbs and a body wrapped in a hard shell!

But the front ends of its arms are not sharp claws, but bony blade arms like a mantis!

"Ouch!"

Recently, a T3 didn't hesitate at all, crushing the ground and punching this special zombie.

The strong wind howled, and the special zombies disappeared instantly.

There were two huge cuts with visible bone on the shoulder blades of T3's back at the same time, and black blood spurted out wildly.

T3, who was unable to lift his arms, was easily beheaded by this zombie. The special zombie standing on the spot paused for a few seconds, and then a blade arm reached out at high speed.

When it retracted its blade arm, a slender zombie with a body length of three meters and five extremely sharp claws penetrated the brain and hung on the blade arm.

S3 type zombie!

"Well... the solitary special zombie was still a famous existence before its rebirth.

Demon Blade Corpse King..."

High in the sky above St City, a light golden ball of light that no one could see or touch rippled slightly.

Shu Youluo looked at the scene below with interest.

There is no way, the body is about to reach a certain critical point, but staying in the super-dimensional flow layer is too boring.

He could only find the only way to escape from his boredom, and there were a lot of subordinates at the base so he didn't have to worry.

So he decided to go somewhere else to relieve his boredom.

It happened that part of the urban area of ​​St City was within the scope of his quantum data, so he came to relax and saw such a scene.

"The combat power of lone special zombies is not weaker than that of high-level mutant beasts of the same level. Beings like the Demon Blade Zombie King are even comparable to beast kings. What are they doing in a small place like this?"

Shu You thought doubtfully for a moment, then put it behind him.

No matter how powerful the Demon Blade Zombie King is, it is just a lone special zombie. As long as it cannot control the zombie swarm, it poses little threat.

He was confident that the Arbiter could kill this corpse king.

In comparison…

Shu You narrowed his eyes and looked at the dozens of special zombies in this group of corpses that could only shoot corrosion balls...

"The Camel Eclipse... is really troublesome."

Shu You recalled it and found that currently in the foundation, only the materials of the Jintai Mechanical Soldier, the Liquid Silver Mechanical Soldier, the Second Generation Sentinel and the Arbiter could resist this kind of corrosion.

The rest of the units will definitely suffer heavy losses under the attack of this corrosive ball, and you can imagine that after the corpse swarm wakes up, the camel eater will definitely be protected in the middle by the corpse swarm.

At that time, even using advanced weapons to attack and kill will be very difficult!

However, the Demon Blade Zombie King should be able to kill most of the Camel Eaters. After all, the advanced source cores of the same type are very useful for lone special zombies...

Compared with the most common S-type and T-type zombies among evolved zombies, Camel Eclipse is obviously more attractive to it!

Of course, if the Demon Blade Corpse King is not strong enough.

Then the only thing left to do is let the arbiter take action.

It's a good thing that he doesn't know. Now that he knows, he can't let him threaten his own troops wantonly.
Chapter completed!
