"The remaining people are three and a half. Almost all have undergone mechanical transformation, and the difference is only in material and thickness." Still moving, Cassia observed the front thinking. The rebel surgeons seemed to have gained an immune system the day after tomorrow, but were limited to steel shell bombs, a weapon that relies on fragments to create damage. The power of fragments cannot penetrate the alloy sheets on these people's bodies, and destroying the skin will only cause some pain.

In less than a minute, Cassia discovered another thing. Even though mechanical transformation was very popular, perhaps due to the limitations of technology and price, not many people replaced the skull with metal. Among the eleven people who died just now, according to the sound of the bullet hit, only one person was a skull of alloy material. This was no different for Cassia. Under the acidic platinum bullet with an ordinary small-caliber blue-silver bullet, there were not many things that could withstand this power.

And even if it cannot be penetrated, the huge kinetic energy acts on the head. It is still unknown whether some surgeons can eat this force on their necks. Even if they eat it, the impact transmitted into the skull cannot be eliminated in a short time. Unconsciousness, and then losing balance is probably the fate of a large number of people. The defense mechanism of the alloy material is similar to that of the black scales, and it relies on its own hardness to defend against external attacks. Both absorb the impact and power very low. If the strength of the protected thing itself does not meet the standard, the result will only look bright and beautiful outside. After enduring too many bullets inside, it will be directly shaken into pieces and thick blood foam.

The four people on the opposite side did not cooperate with the smoke generated by the rushing explosion. After firing the bullets in the magazine, they quickly retracted and retreated to the edges of two steam furnaces. Among them, the captain was holding the communicator to contact others, looking vague and excited.

Two of them immediately opened the small room next to the furnace control room, which was similar to the storage room. Two heavy machine guns that had been assembled and debugged were pushed out. They were fixed on a small car. There was a bulletproof baffle in front of the heavy machine gun and a mechanical shock absorber was added. Two large boxes of bullets were estimated to be equipped with ammunition boxes of about 5,000 rounds and fixed on the side of the heavy machine gun.

There is also a simple barrel cooling mechanism, the most common air cooling, which is not very effective, but it can increase the time for the heavy machine gun to continuously output fire for about ten seconds. And these ten seconds may be the bullet net woven by hundreds of platinum bullets.

Two movable heavy machine guns guarded the mines to the steam furnace, one left and one right, while the remaining two were used as support.

"The Imperial Surgeon should have told them that I have temperature sensing ability." The remaining four people were surrounded by the temperature evaporated from the steam furnace. The range of action they could be determined and regulated by the Imperial Surgeon on the spot in the past few days. Several people were cautious when moving, and there were invisible rules.

Although the information was wrong, it did achieve results. The increased "buzzing" sound did have a certain impact on Cassia's sound wave detection. Several people faced the passage, staring at the still flowing and slowly slowing smoke, as if they wanted to see the enemy's movements.

It is expected that the reinforcements from the rebel forces will arrive at the steam furnace for three to five minutes. Cassia believes that it is necessary to put some pressure on these four people so that they will let more surgeons support here, which can alleviate the difficulty of attacking Evan, Wimmer and others on the other hand. Another point is that if you drag most of the surgeons, the chances of the two men successfully retreating will be much higher. Cassia feels that in the future, there may be some places that need their help in the expansion of business in the Kingdom of Chil.

Cassia pulled off two steel shell bombs and removed the pull-up ring and read the number of seconds. The smoke in her eyes seemed to not exist and could not block his vision. At a perfect time, Cassia walked forward a few steps, and the steel shell bomb threw a smooth arc and sank into the smoke.

Two seconds later, there was almost no difference between the two steel shell bombs, and two heavy machine guns exploded.

After observing the heavy machine gun, the two men subconsciously hugged their heads, and the fragments directly tore the skin on the top of their heads and a small part of their faces. The brief pain made them feel dangerous. The next moment, the captain and the other person began to shoot blindly into the interior of the passage, and then the two heavy machine guns also spit out flames more than one meter long. In the sound of the crisp shells falling to the ground, Cassia watched the rock walls on the passage "rustled" and splashed into pieces of gravel flower fountains. In just a few seconds, the place where the bullets were concentrated had decreased by nearly 20 to 30 centimeters thick.

Waiting for the opportunity, about eight seconds, when the four of them released the trigger one after another, Cassia approached the ground and rushed to the center of the passage. According to the sound wave guidance, he fired five shots in a row at the front baffle observation window of the heavy machine gun.

The angles are different, but the final bullet points are all gathered on the center of the bulletproof glass placed in the observation window. It is estimated that it is nearly thirty centimeters thick, so it is not an exaggeration to say that it is the bulletproof glass wall. But thinking that this may be their last defense facility, it becomes natural.

The first bullet directly made the thickened bulletproof glass covered with flowers, and the warhead was embedded inside, and it could penetrate completely in just five or six centimeters. The subsequent bullets followed one after another, and the extremely small time difference made the observation window explode, continuing to pass through, and the enemy's heads behind it opened.

Knowing that this would be the result, Cassia fired five shots and held up his body with one hand and jumped up. On the way back to the previous position, she opened the sixth bullet and exploded a small-diameter red copper pipe that came out of the high-pressure steam tank.

With the sound of explosion, the high-pressure superheated steam that obtained the breakthrough immediately rushed the pipe into pieces. The high-temperature white steam filled the cavity in a very short moment, and the smoke in front of the passage was also blown away.

The next moment, a whole red light appeared with a beeping sound, and the "bounce" sound of high-pressure steam impact also came to an abrupt end.

Safety monitoring plays a role and starts the shutdown valve on the pipeline.

The heavy machine gun roared intermittently again, and the air it breathed brought the temperature of burning people's throats. Seeing the vague shadow of the three people running towards the control room, Cassia immediately followed their steps, loaded the revolver with bullets in the middle, and fired them continuously.

Did the two people behind him keep up? As the captain who is defending and monitoring here on a daily basis, there is no time to care. The gunshots only made him instinctively shrink his head. Just when he was lamenting that he was lucky, he lost his balance and fell to the ground.

Thinking about what happened to him, a severe pain came from his left leg. He touched it and the section below his knee had been broken by a bullet.

The temperature around him was very high, but he still couldn't stop his cold sweat from experiencing all over his body. He didn't dare to stop at all. He moved with his hands and another foot until he entered the control room, and he had time to lean against the wall and breathe.

"Captain Janet! Captain Janet!" An urgent call.
