Several serial traps at the entrance of the subway station were easily cracked by Qi Lin and No. 4, and the two rushed into the subway tunnel with weapons, but before they could penetrate more than 100 meters into the tunnel, a dense rain of bullets stopped the footsteps of the two.

"It's an automatic defense machine gun...... It seems that the entrance chosen by the other party is indeed not here, otherwise these machine guns hanging on the top of the tunnel would not still exist. Qi Lin said.

Using the overlapping dragon scale plates as cover, Qi Lin used the M107 sniper rifle to destroy the automatic defense machine guns one by one.

However, the mastermind's methods were obviously not limited to this, as soon as the last machine gun exploded, dozens of skeleton-like mechanical soldiers staggered out of the depths of the tunnel.

The end of the left arm of these mechanical soldiers is a pair of rusty hook claws, and the right arm is directly welded with the barrel of a large-caliber assault rifle, this simple and crude combination made Qi Lin sigh slightly, after all, they are only facing the "mastermind" simulated by the "organization", and the combat effectiveness of these low-cost mechanical soldiers may not be as good as the model produced by Yamato Heavy Industries.

If their target is the real mastermind, they will not be faced with these rudimentary mechanical soldiers, but with a large number of biochemically modified mutated creatures and an almost endless number of flesh golems.

No. 4 stacked the four layers of dragon scale plates on top of each other and put them at the front, and the bullets of the mechanical soldier hit the outermost layer of the dragon scale plates, constantly making a crisp sound, constantly echoing in the tunnel, while Qi Lin followed behind No. 4, poking out a muzzle from time to time, killing a mechanical soldier in one blow.

It seems that in order to save materials, these mechanical soldiers don't even have the most basic armor, the power parts and core chips are so naked that Qi Lin doesn't even need the M107, just 5.56 NATO shells can do one shot.

"It doesn't feel right...... The strength of these mechanical soldiers is too weak, even if it is a simulated mastermind, it is impossible to only have this strength, otherwise it will not be able to achieve the effect of training at all......"

It only took Qi Lin a little more than three minutes to put all the mechanical soldiers on the ground, which was even shorter than the time they had to settle a breakfast.

"I think it's a little weird...... None of the target planes we face in our daily training are so weak...... It was as if the weapons were just welded to civilian robots, and there was no sign of being remotely controlled, all of them were in a state of self-discipline, and the strafing hit rate was very low, with more than a third of the bullets hitting the walls and ceilings on both sides. Number Four further analyzed.

"I estimate that the main force of the main brain is dealing with those two guys, after all, it is a simulated main brain, and the computing power is limited, and for the uninvited guests of the two of us, there is only this kind of self-discipline robot that does not enter the stream to resist it."

"Are we too late?"

"It's hard to say, we have to speed it up...... Damn, it's the first time I've hoped that the mastermind's strength can be a little stronger, and it's good to drag those two people to death. ”

After saying that, Qi Lin quickly ran towards the depths of the subway tunnel......

……

……

Ten minutes later.

"Whew...... Is this what the captive called the 'Underground Hub'? ”

The so-called subway is just a "disguise", only the section of the platform is modeled after the subway station of the old era, and the length of the tracks is only less than a kilometer.

After passing through this tunnel, an empty underground space appeared in front of Qi Lin and Four.

"This ...... This must be a small Vault remodeled......" Four said with some surprise.

"Possibly." Qi Lin nodded.

What appeared to the two of them was a completely mechanized city...... No, it's more appropriate to say it's a factory than a city, but at this time, this giant factory seems to be in a state of stagnation, and the two of them can see at a glance a large number of skeleton-like mechanical soldiers hanging on the hook frame of the assembly line, and next to the assembly line, there are also a large number of cast iron armor plates.

"It seems that the reason why the mechanical soldiers we met are so weak is because they are all half-finished products, so we have to thank our opponents."

"They're there!" Pointing to the center of the Factory, Four said that it was an all-metal machine room, the door of which had been broken and replaced by an advanced shield with a shooting hole, the "Immortal Shield".

Compared with the dragon scale plate carried by No. 4, the weight of the "Immortal Shield" is more than twice that of the material, not only due to the difference in material, in terms of thickness, the Immortal Shield with a thickness of 20 centimeters is more than enough as the frontal armor of the main battle tank, and the thickness of the dragon scale plate is only 4 centimeters.

And can be flexibly combined, deformed, can be used as a bulletproof shield, and can be used to build temporary fortifications of the dragon scale plate is different, the immortal shield is to put it bluntly a high enough defense of the "door panel", few people in mobile combat to choose this kind of bulky equipment, this thing is often used to provide cover for the fixed heavy machine gun on the position, although a large number of advanced technology is used, the cost is also very high, but this embarrassing equipment has not been developed when it has been on the verge of elimination.

Before, Qi Lin still wondered why the organization would provide such a thing as the "Immortal Shield" for them to choose from, but now, the other party's approach was obviously to give full play to the role of this immortal shield.

Not to mention the large-caliber assault rifle in the hands of the mechanical soldiers, even small-caliber artillery can't do anything with this iron lump, as for some mutated creatures that have undergone simple biochemical transformation, they can't even get close to the door of the machine room, and they are torn to pieces by the tongue of fire spit out from the shooting hole.

The other party has already occupied the computer room, and the cracking operation is obviously underway, and if the simulation mastermind can't break this situation, then it is only a matter of time before the distance is closed.

"What are we supposed to do? The Mastermind's men can't break through that immortal shield, and there's nothing we can do with it. Four asked.

As mentioned earlier, the thickness of the immortal shield is 20 centimeters, and the position of the shooting hole is even deeper, if it is not a vertical angle, even if the sniper aims at the shooting hole, it is difficult to hurt the person behind the shooting hole.

In order for a bullet to pass through the shooting hole, the trajectory and the immortal shield must form a near-vertical angle.

The structure of the entire underground hub is a round well that spirals downward from the edge, the machine room and the factory are located at the bottom of the well, and Qi Lin's position is on the edge of the well, if Qi Lin wants to find a suitable shooting angle, he needs to face not only the muzzle of the opponent's gun, but he also has to fight his way out of a large number of mechanical soldiers and biochemical monsters.

It's almost unattainable.
