The bullets in the restaurant were still pouring towards the door, and the people inside were shooting and approaching them, but fortunately, their marksmanship was not good, and the penetration of the bullets was not good, and the walls that Tang Shuxing and the three of them hid on both sides of the door of the restaurant could completely avoid their attacks.

"Second sentence, we have to leave immediately!" Gu Huaiyi stared at the few yellow mist that were gradually drifting, and when he raised his eyes, he could see a white light that was not bright in the distance—there were people who were swallowed by the yellow mist and exploded.

"What about the people here? Watch them die? Tang Shu took a look at it, and was forced back by the bullet again, "They can't everyone be the most heinous bastards, right?" There are always innocents! ”

"It's already a war!" Gu Huaiyi looked at him and said, "In war, there is no such thing as innocence!" ”

"Let's go! It's too late! It's time to get there! Ji Kefeng looked at one of the yellow mist masses that were less than three meters away from them.

"Damn it!" Tang Shuxing shouted loudly, "Ceasefire!" Cease fire! The poison gas has arrived, if you don't want to die, you should quickly cease fire and leave, I didn't lie to you! Run! ”

The gunfire gradually stopped, because many people in the restaurant also saw the gradually drifting yellow mist, but there were still brave people who slowly stood at the window with guns and looked out cautiously, and at the same time someone asked, "If it is poisonous gas, why don't you run?" ”

As he spoke, the gunshots rang out again, and several bold people saw that Tang Shuxing and the others did not fight back, and rushed to the door with guns, and Tang Shuxing and the others had to flash sideways to the other side of the wall outside the restaurant, at the same time. The yellow mist also drifted to the door, and several gunmen rushed out directly into the yellow mist......

"Bang dang-" The guns in the hands of several people fell to the ground, and they began to rub their faces desperately with their hands, constantly shouting "It's cold" in their mouths, and after the yellow mist passed them, they floated towards the restaurant, and when the yellow fog passed, Tang Shuxing and the others and some of the people standing at the window saw that the faces of the gunmen who had been swallowed by the yellow fog appeared with soybean-sized abscesses.

"Poison gas! It's poison gas! Someone in the window shouted after seeing clearly, turned around and ran towards the inside of the restaurant, he shouted. The people around immediately scattered. Several people were knocked to the ground, and two of them had their arms and legs broken by the others.

"They're changing, run!" Gu Huaiyi dragged Tang Shuxing to get up and ran across the street, followed by Ji Kefeng. Just ran across the street. The few people who were already kneeling in the doorway had become transparent. Immediately afterward, a circle of silvery-white light flashed, burning a large hole directly at the door of the restaurant.

The people in the restaurant ran towards the back door, when the leader opened the back door. However, I found that several yellow mist masses floating up and down had already gathered at the back door, and these things seemed to be alive and conscious, squatting in the rear, surrounding the people in the restaurant.

When the people at the back door were stunned and gradually retreated, two of them rushed out of the crowd, shouting at the same time: "Staying here is a dead end!" ”

But at the moment when the bodies of the two people passed through the yellow mist, they also froze, and began to exclaim, "It's so cold", and then rubbed the skin on their faces. As they turned to face the people inside the back door of the restaurant for help, those who were still alive stared at their bodies as they began to become translucent, then transparent, and then suddenly flashed with a silvery white light......

Under the tree across the street, Tang Shuxing and the three of them looked at the white light flashing in the window of the restaurant, knowing that all the people in the restaurant were finished, just as they were about to leave, there was an explosion in the restaurant, the explosion started from the location of the kitchen, and began to explode continuously along the underground gas line, and in just less than a minute, the entire restaurant was blown to ashes.

The three of them stood across the street and looked at the ruins of the restaurant that continued to burn with thick smoke, and after only ten or so seconds, the yellow mist slowly floated out of it and began to wander around, hunting other living creatures, even stray cats and dogs.

"Have you noticed that the time it takes for someone who has been shrouded in that yellow fog to change has decreased?" Tang Shuxing looked at the yellow mist floating in all directions.

"Hmm!" Ji Kefeng nodded, clenching the gun in his hand, "It's shortened, the person I saw in Philadelphia Independence Hall, the change time is at least a few minutes, but here it is only 10 seconds at most." ”

Gu Huaiyi raised his feet and walked to the right: "In just 10 seconds, the appearance of pus on the face has been completed, the body has become translucent to transparent, followed by the process of silent explosion, it seems that these yellow mist floating over have mutated to some extent, but I don't know if the Dao is artificial, or if it is caused by something I came into contact with." ”

"Should we cross the river to the island now? While it was already dark. Tang Shuxing turned to look in the direction of the river, but when he turned his head, he could see helicopters flying there, and from the light of the searchlight, at least three or five helicopters were searching along the river.

"Let's go to the river and see how it goes." Gu Huaiyi turned around and ran towards the river, and when the three of them ran to the river, they were already stunned by the situation in front of them - the entire city on the opposite side was completely shrouded in yellow mist, not only that, but the height of the yellow mist also climbed, judging from the shrouded floor, the height was at least twenty meters. There was also a single yellow mist floating above the river, and although the search boat of the Marine Police was slowly passing by, the people on it were all wearing chemical protective suits, and no one dared to stand on the deck, all standing in the cockpit that locked the door, looking out with frightened eyes.

"It's miserable." Tang Shuxing put down the binoculars, "We can't cross, at least we can't cross the river in a short time, although we can swim over, it's impossible not to be discovered." ”

"Master Ji, how long can you dive underwater?" Gu Huaiyi turned his head sideways and asked Ji Kefeng, who was lying on the low wall on one side.

"I don't know the road, I don't have the opportunity to experiment more, I guess it's no problem to dive into half of the width of this river." Ji Kefeng replied, checking the gun in his hand, although in this case, the gun probably wouldn't be of any use.

Tang Shuxing shook his head: "The plan to cross the river is suspended, if we are trapped on the island, facing this kind of large-scale search." We have no chance of escaping at all, and we can only wait for the U.S. government to completely lock down Philadelphia and the surrounding area before we act. ”

"Yes." Gu Huaiyi nodded and crawled backwards towards the back, "They can't find a solution to this yellow mist poison gas for a while, so they can only temporarily block these two cities." ”

"We have to find a place to hide first, we have to find a place where no one is and no one is going to go." Ji Kefeng looked around, "Now it seems that everywhere is dangerous, even cats and dogs will turn into a hot bomb that will explode at any time." ”

"Only living creatures breathe. Breathing things don't change until they inhale the yellow mist. What about the dead? Tang Shuxing looked at Gu Huaiyi and Ji Kefeng, "It seems that we can only go to a funeral parlor or a cemetery or something like that, that kind of place may be the safest place right now, because there are very few people there on weekdays." ”

Gu Huaiyi and Ji Kefeng nodded in agreement. Turn around and sneak into the city at night. Just as they left. The helicopter formation of the US anti-chemical warfare unit flew from the other side of the river, shuttled through the urban forest, and finally landed on the lawn next to the Independence Hall.

Because the intelligence sent back by the advance personnel shows. The yellow mist leaked from under the cracked road next to the Independence Hall, and the anti-chemical warfare forces had reason to suspect that the terrorists had placed the relevant biological and chemical weapons in the sewers.

"Groups C and D are arranged to assist the ground forces in establishing a defensive line within a kilometer of the perimeter, while searching for and rescuing civilians who may still be alive, having them each carry two to three gas masks, as long as they do not inhale that yellow fog, they will not explode, but if civilians are found inhaling, they will immediately evacuate the area." The on-site commander of the anti-chemical warfare unit had a brief meeting with other team leaders wearing chemical protection suits on the side of the road, "Group A and Group B follow me, Group B is on guard around the crack, Group A follows me down, the assault group of the ground forces has entered, we need to catch up with their speed, if any suspicious characters are found below, after the warning is invalid, you can shoot directly, but be careful, don't hit anything that may cause a secondary explosion, do you understand?" ”

"Understood, sir!" The leaders of the other four groups nodded.

"Good! Let's go! The commander raised his hand and made a circle overhead, and the leaders of the other four groups immediately ran away with their rifles, each with his own team members to the predetermined area.

The commander trotted with a chemical weapons expert towards the mouth of the fissure, around which barbed wire had been pulled up, and on all sides stood soldiers of the Army Special Forces with lights hanging on their shoulders, and the visibility in the yellow fog was so low that they could only see about three meters in front of them.

"Sir! The commandos have entered, very deep underneath, already deep under the underground waterways, and there are not enough rope ladders, you can only rappel them! A second lieutenant from the army special forces stepped forward and said loudly, because he was wearing a high-density gas mask, he couldn't hear the other party if he didn't speak loudly.

The commander nodded, watching the second lieutenant point to the iron pillar that had been nailed to the ground and reinforced, with ropes tied to the iron pillar, he turned to look at the chemical weapons expert next to him and asked, "You shouldn't have a problem, right?" ”

"I don't know what to do!" The expert shook his head, "I haven't had this kind of training since I left Langley. ”

The second lieutenant of the army special forces judged from the conversation between the two that the expert was from the CIA, he stepped forward and hung the iron buckle of the rope on the expert's waist, connected the auxiliary equipment, and then said loudly: "Grab the rope with one hand, and press the switch of the auxiliary with the other hand, as long as you press it, it will automatically fall down, and when you need to stop, you just need to release your hand, understand?" ”

Looking at the crack under the black hole, the expert was already pale with fright, but he still made an "OK" gesture with his hand, and then with the help of the commander and the second lieutenant, he hung himself on the rope hook and hung it on the side of the iron post. At the same time, the five anti-chemical warfare soldiers of Group A were also ready to rappel, and after the commander pointed his finger down, he immediately pressed the button on the auxiliary device and slid down at great speed.

"Check the coms again!" The commander waiting above pressed the intercom switch on his wrist, "Everyone modulates the continuous call state." ”

Subsequently, the soldiers of Group A reported their communications one by one, and after learning that there were no problems with the communications, the commander led the experts to slide down the rope as fast as possible.

Although the bottom of the cave was dark and full of that yellow mist, it could almost be said that he couldn't see his fingers, but he still closed his eyes vigorously, and waited for the commander to say "stop" before he suddenly pressed the auxiliary device on his waist to stop himself, but because of fear, he forgot to turn on the shoulder lamp, so he had to hang there and wait for the "rescue" of others.

"Untie him." The commander turned on the refractive lights on his shoulders and helmet, and the light sources on the other soldiers around him, so that he could barely see the motionless expert hanging on one side.

Two soldiers stepped forward to untie the expert, and helped him open the instrument he was carrying, and handed it to him.

The expert sat on the ground, panting for breath, and the other soldiers dispersed in turn, contacting the commando soldiers and keeping watch.

The commander stepped forward and squatted down in front of the expert, pointed to the position under his mask and said, "Sir, there is an LCD under your hood, very small, only the size of a watch, with a percentage on it, can you see it?" ”

The expert squinted down at him, then nodded.

The commander added: "What is the current number?" ”

“96%。” The expert nodded, "This is a digital display of oxygen content?" ”

"That's right! So if we're going to live, we have to go back to this position when we have at least 15% of the oxygen left, and then go back along the rope, otherwise we're all going to die, and if we just have one of us exploding, everyone else will have to be burned clean! The commander grabbed the expert, helped him up, and ordered the other soldiers to move on.

The expert walked next to the commander, shining the light on his wrist on the ground, and found that the ground was very flat, but there were traces that looked like a tank had been crushed, and immediately pointed to the ground and asked, "What is this?" Excavated by hand? ”

The commander shook his head: "I don't know, we're here to figure this out." ”

"Sir, the commando team has lost contact." The leader of Group A ran back from the front, "The front is very deep, and we found the glow sticks left by the commandos along the way, but the glow sticks are gone ten meters in front, and the yellow fog is getting thicker and thicker, and the lights can't shine at all." ”

"Try to get in touch again." The commander stopped, pulled out the pistol from his waist, handed it to the expert, let him hold it, and asked, "Will you use it?" ”

The expert nodded and pointed the muzzle of the gun in front of him, and the commander shook his head and put his finger on the place of the safe: "It seems that you will not, remember, open the safety ...... before shooting"

As soon as the commander said this, a dazzling white light flashed in front of him, and he realized that someone had inhaled the yellow mist explosion, and immediately pushed the expert to the wall, and at the same time asked with the intercom: "Everyone in Group A reports their location!" Fast! ”

Immediately after that, three people in Group A immediately reported back, and after listening to this, Group Leader A stood aside and looked ahead and said, "Sir, Hamir and Kane didn't answer, I suggested-"

"Take back your advice, soldier." The commander made a gesture to keep up with him, and asked the team leader to take care of the expert, "We can't back down, and there's no way to back down......" (to be continued......
