Steel steam and flame

"There's something mixed in the air." Cassia noticed the slight burning sensation, "It's probably poisonous gas." He couldn't think of other drugs that could be mixed into the air and cause the surgeon's skin to react like this.

Without breathing, Cassia tried her best to cover the exposed parts of her body with clothes. Then in the darkness, he retreated out of the big wooden box in the opposite direction according to the memory he had when he hid in. As he moved gently in the narrow space of the carriage, his body seemed to have completely turned into a soft body, making no sound in the carriage.

When she came to the skylight on the top of the car, Cassia tried to push it. It was easy and it was not blocked due to a little rust.

He didn't pop his head out rashly, hiding inside and listening to the noise outside. Large clouds of gray smoke poured into the car through this gap. Cassia could see a square patch of gray sky, and nothing existed in it.

There is no longer the chaos of not long ago. The storage warehouse is now very quiet, with very few sounds, and all objects seem to be at rest. Or maybe it’s because everyone is cautious.

Only the gunfire that sounded from time to time became the only sound now, and its position kept changing. All the shooters knew that in the smoke, the sound was their other pair of eyes.

Cassia squatted under the sunroof of the train and waited quietly. At this time, the gray smoke invaded his eyes, which suddenly became sour, and tears began to secrete in large quantities from the lacrimal glands. He quickly closed his eyes tightly. The smoke did not seem to simply block his vision.

A mask is needed, Cassia thought. The smoke should have been caused by the people on Norentel's side. He was thinking in the carriage, the air was mixed with smoke and toxic substances, although as a surgeon, he could not breathe for more than half an hour. But that can only be done in a perfect state, without moving, without thinking, and just concentrating on holding your breath without inhaling.

Once the body is functioning, the operator's system is essentially like a walking steam furnace. The steam furnace requires the electricity in the radiator to heat the steam, and the body of their surgeon relies on the blood tempered by its own continuous evolution. And air is an essential thing for complete combustion of blood.

You can go without breathing for a period of time during a battle, but this time will definitely not last long. There is still poison in the air now, and the touch on the skin is getting stronger. Cassia thought that her original position should be very close to the source of the poison. In other words, the air inlet of the air circulation system is very close to the source of the poisonous gas.

After finding the mask, quickly change to a safe location and hide. Cassia herself was not easily drawn into this battle. Hiding well and waiting for the train to leave the mountains was what he was most happy to see. But at this time, he thought of the powerful sniper he had discussed with the major.

Do you know that through some kind of strange perception, you can penetrate the steel plates arranged in rows and know that they are hiding in the carriage? The power of her sniper rifle and the rearranged protection could not stop it in the slightest.

At this time, Cassia was about to go out. As soon as she poked her head out, there was a slight sound outside. Someone climbed onto the roof of the heavy train from the end. At this moment, his eyes opened a slit. The gray smoke shrouding the end of the rearrangement seemed a bit light. Four or five meters away, Cassia could see the flow of smoke illuminated in advance due to the advancement of human bodies.

He quickly closed the sunroof lid, took out a tactical knife at the same time, put his ear against the steel structure on the roof of the car, and waited quietly under the sunroof.

Even the slightest sound reached Cassia's ears through the top of the car. He counted the footsteps. There were eight people in total, forming a long queue, their footsteps moving gently on the roof of the car.

It might be to go around from behind to outflank the enemy team. Cassia thought that if he were to formulate this battle plan, he would definitely take advantage of his numerical advantage and send several teams to go around behind the enemy from different directions. . He counted the people who passed by the skylight one by one. After everyone had passed him for a second or two, he opened the skylight again and got out of it lightly.

During the whole process, he seemed to have lost his own entity, and even the gray smoke around him was only naturally carried by the air flow in the warehouse.

The steps are lighter, and the concealment of one's own aura is deeper. Cassia followed the team, and within a few steps, he approached the team advancing in front.

Sure enough, they were all wearing masks. Cassia said in her heart, her face expressionless, her body naturally relaxed and she continued to follow. About ten meters ahead is the connection between the two carriages. There is a layer of foldable iron protection there, and inside is the walkable passage between the carriages. The hardness of the iron sheet certainly cannot support the operator's weight. The span there is about two meters, and they can only jump across it lightly.

When we got there, just as Cassia predicted, the eight people in front jumped over the connections one by one in an orderly manner, and then slowly pushed forward again. When the last person took off and his feet left the top of the carriage, Cassia's hands stretched out from behind him with a "whoosh" sound, and in a short moment intercepted his body in mid-air, pinching it with one hand. She grabbed his neck, and in the process of lifting him in front of her, she knocked him unconscious with a knife.

Then while laying his body down, Cassia skillfully took off his clothes and mask and put them on himself. Only then did he speed up step by step and follow up, ranking in the eighth position of that team.

Fortunately, this operation was carried out silently, and the people in front focused most of their attention on the front shrouded in gray smoke. They did not realize that the last person had been replaced by the agile Cassia.

"This should be the carriage with those cylindrical cans." Cassia followed the team. After passing several long carriages, he wanted to immediately find a skylight and get into the cargo compartment to hide, waiting for retraining. Drive away. But the car under my feet didn't have a skylight structure at all, so I had to wait until the next car.

The surrounding gray smoke began to become thicker and flow faster. Soon you may encounter enemies hiding around the rear lines. Cassia hoped to go faster so that she could reach the next carriage as soon as possible and find a skylight to squeeze into the cargo and hide.

While he was thinking about this, the perception that had been scattered around him suddenly became abnormal, and then the gray fog around him also began to flow unnaturally.

An enemy is coming. Cassia's body was immediately nailed to the spot, and the cross pupils opened in his eyes for an instant. At this moment, he captured the flow of the gray mist more lightly. His brain was also working rapidly. The moment before the enemy attacked, he accurately calculated the enemy's position based on the flow direction of the gray mist. The body that was nailed in place was under the control of the brain, like a servo machine in an industrial machine, and began to adjust its movements accurately and slightly. The right hand holding the tactical knife was very fast, and it passed through the gray fog silently. Unclear white light. When the enemy's sharp knife reached his own jaw, the tactical knife in his hand penetrated into the enemy's brain one step ahead.

At this time, an identical mask appeared dozens of centimeters in front of Cassia. Through the lenses of his glasses, he saw the enemy's final surprise and panic. This expression was frozen on the enemy's face forever. The two stood looking at each other like this for a few seconds. During this period, Cassia never turned her head to look ahead. The scene in front of him had been roughly sketched out in his head.

All the seven people in front were killed by the enemy silently. Because there was a layer of gray fog between them, most of the surrounding scenes were blurred. He couldn't see clearly the scene in front of him, and the enemy couldn't see clearly what he was here. They were all rough outlines. The enemy didn't seem to know what was happening here.

Cassia looked ahead with her peripheral vision, and naturally put down the body she was holding in her hand with the enemy.
