"There's something in the air. www.biquge.info The subtle burning sensation made Kasia perceive it, "It's probably poisonous gas." He couldn't think of any other drug that could get into the air and make the surgeon's skin react in this way.

Without breathing, Kasia tried to wrap the exposed part of her body in her clothes. Then in the dark, he retreated backwards from the large wooden crate according to the memory of the time when he had been hiding in. As he moved gently in the narrow space of the carriage, his body seemed to become completely soft, and he did not make a sound in the carriage.

Coming to the skylight at the top of the carriage, Kasia tried to push it, but it was easy and not blocked by a little rust.

He didn't pop his head out of the way, he hid inside and listened to the noise outside. Large clouds of gray smoke poured through the gap into the carriage. Kasia could see a boxy gray sky in which nothing existed.

There is no longer the chaos of the recent past, the storage warehouse is now quiet, there is very little noise, and everything seems to be stationary. Or is it because everyone is careful.

Only the occasional gunshot was the only one ringing, and the position was constantly changing, and all those who fired knew that inside the smoke, the sound was their other pair of eyes.

Kasia crouched under the train's skylight, waiting. At this time, the gray smoke invaded his eyes, and suddenly became sour, and tears began to secrete a large amount from the lacrimal glands. He quickly closed his eyes tightly, and the smoke didn't seem to be as simple as an ordinary obscuring the field of vision.

A mask was needed, and Kasia thought about it, the smoke must have come from the Norrentel side. He thought in the carriage, the air mixed with smoke and toxic substances, although as a surgeon, he could not breathe for more than half an hour. But that is in a perfect state, without moving, without thinking, only concentrating on holding and not inhaling.

Once the body is functioning, the surgeon's system is like a walking steam furnace. The steam furnace needs electricity from the glow tube to heat the steam, and the body of their surgeon is tempered by its own continuous evolution and tempering of blood. And air is the indispensable thing that makes the blood burn completely.

It is possible to go without breathing for a while in battle, and this holding out time is definitely not long. There was still toxicity in the air now, and the skin felt more and more intense, and Kasia thought that her original location should be very close to the source of the toxicity. In other words, the air intake of the air circulation system is very close to the source of the poisonous gas.

Once you've found the mask, quickly change to a safe location and hide. Kasia herself was not well drawn into this fight. Hide and wait for the heavy train to sail out of the mountains, which is what he is most happy to see. But then he thought about the powerful sniper he had discussed with the Major.

Do you know that you can penetrate the steel plate of the retrain through some strange perception, and know that a few of them are hiding in the carriage? The power of her sniper rifle, the protection of the retrain can't stop the slightest.

At this time, Kasia was about to go out, and his head poked out a little, and a small sound sounded outside. Someone climbed onto the roof of the retrain from the end of the retrain. At this moment, his eyes split apart. The gray smoke that shrouded the end of the retrain was a little faint, and four or five meters away, Kasia could see the flow of smoke that had been illuminated in advance as the human body advanced.

He hurriedly closed the lid of the sunroof, and at the same time took out his tactical knife, and waited quietly on the side under the sunroof with his ears against the steel structure on the top of the carriage.

Even the slightest sound reached Kasia's ears through the roof of the carriage. He counted the footsteps, and there were eight people in total, forming a long line, and his footsteps moved gently on the roof of the car.

It was possible to outflank the enemy's team from behind, and Kasia thought that if he came to make this battle plan, he would definitely take advantage of his numerical advantage and send several teams to go around the enemy's back from different directions. One by one, he counted the people who had walked past the skylight, and it was not until a second or two had everyone walked past him that he reopened the skylight and deftly slipped out of it.

During the whole process, it was as if he had lost his physical body, and even the gray smoke around him was only naturally driven by the flow of air in the warehouse.

The steps are lighter, and the concealment of one's own breath is deeper. Kasia followed the group, and within a few paces, he approached the advancing group in front of him.

Sure enough, they were all wearing masks, and Kasia said a word in his heart, his face was expressionless, and his body naturally relaxed and continued to follow. Ten meters ahead, there is the junction of the two carriages. It is protected by a folded iron sheet, and inside is the walkable passage at the junction of the carriages. The hardness of the iron sheet certainly does not support the weight of the surgeon, and the span there is about two meters, and they can only jump over it lightly and lightly.

When they got there, as Kasia had predicted, the eight men in front of them jumped over the junction one by one in an orderly manner, and then slowly advanced forward again. When the last man jumped and his feet left the roof of the carriage, one of Kasia's hands came out from behind him with a "whoosh", intercepted his body in mid-air for a short time, pinched his neck with one hand, and stunted him with a knife in the process of lifting him in front of him.

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

Thankfully, the operation went on in silence, with most of the attention of those in front of them focused on the gray smoke ahead. They didn't notice that the last man had been replaced by the sharp-moving Kasia.

"This is supposed to be the carriage with those cylindrical jars. Kasia followed the procession, and after passing several long carriages, he wanted to find a skylight and get into the cargo compartment at once, and wait for the heavy train to leave. However, the carriage under his feet does not have a sunroof structure at all, and the plan can only wait until the next carriage.

The gray smoke around it began to thicken and flow more rapidly. It may not be long before you encounter enemies hiding in various places along the recolumns. Kasia wanted to speed up a little faster, so that she could get to the next car as soon as possible, find a sunroof and 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 mist around him also appeared to flow unnaturally.

An enemy is coming. Kasia's body immediately snapped to the spot, and his eyes opened in an instant, and the flow of gray mist was captured by him more gently at this moment. His brain was also racing rapidly, and he accurately calculated the enemy's position based on the direction of the gray fog before the enemy attacked. The body pinned to the spot was under the control of the brain, like a servo machine in an industrial machine, and began to adjust its movements precisely and slightly, and the right hand that grasped the tactical knife was very fast, and directly slashed silently through an unclear white light in the gray mist. When the enemy's sharp knife reached his own jaw, the tactical knife in his hand stabbed into the enemy's brain first.

At this time, an identical mask also appeared a few dozen centimeters in front of Kasia. Through the lenses of his glasses, he saw the last of his enemy's surprise and panic, an expression that had been frozen on his face forever. The two stood staring at each other for a few seconds, during which time Kasia did not turn her head to look ahead. The scene in front of him had been roughly pre-sketched in his head.

All seven of them were killed by the enemy in silence. Because there was a layer of gray fog separating him, the surrounding scene was mostly blurry, and he couldn't see the scene in front of him clearly, and the enemy couldn't see him clearly, all of them were rough outlines. The enemy didn't seem to know what was going on here.

Kasia leaned on his peripheral vision to observe the front, and naturally put down the corpse he was holding in his hand with the enemy.
