In Baiyun City, in the quarantine zone, a swarm is forming outside the high-rise buildings of Shuguang Technology Group Co., Ltd., and almost all the mercenaries want to break through the siege of the undead......

All mercenaries know that the top mercenary team will soon enter the building, and if they stay outside, they will only become the target of the undead and killed. Unwilling to leave and mentally aware of wanting to live, most of the mercenaries entered the building. As for the remaining mercenaries who don't know whether they are alive or dead, the top mercenary team doesn't care so much, they just throw them outside the building.

When all the top mercenary teams entered the building of Shuguang Technology Group Co., Ltd. one after another. The mercenaries who were left behind, and the mercenaries who didn't plan to enter the building, suddenly realized their stupidity. I was meant to enter the building, so why not enter if I had the chance? Danger is an essential situation.

When the mercenaries were about to enter the building, they were desperate to find that their stupidity had led to death. Among the undead treachers outside the building, the low-level ones have already been transformed into middle-level, or high-level undead treachers. And these undead tricksters who are gradually recovering, without strong firepower, naturally regard the lone weak mercenaries as targets.

In the case of being alone, the lone mercenaries are weak, and under the straight knives of the undead and the treacherous, or the fists and feet, they are quickly reduced to pieces of minced meat, or meat balls, and then ...... reduced to absorbed raw materials......

As for the mercenaries who entered the building, due to the fear and awe of the unknown, what they did was not much different from what Yan Ming had done before, and they searched almost every corner of the floor before the mercenaries found some items that had been submerged and missed. Then, the mercenaries searched floor by floor, and when there was no danger, the top mercenary team no longer acted as shrunken turtles, but led the mercenaries to the forefront.

When these mercenaries who moved quickly arrived at the 21st floor where Yan Ming and the others were, they had been to the steel safe house, but they did not find the security door hidden behind the hanging paintings. When the mercenaries reached the 22nd floor, they found that all the traces of the battles were intact, and they did not feel as passive as before.

So following the traces of these battles, the mercenaries found a lot of ammunition, or found a black substance that gradually turned into clear water. As the mercenaries continued to explore, more and more black substances were discovered, and many mercenary corpses were also found. Faced with these situations, the leaders of the top mercenary team on the 59th floor gathered together to discuss the corresponding strategies.

At this joint eye, the mysterious team wearing black leather combat suits actually killed from the top of the floor. And in front of these mysterious teams, the target of the hunt turned out to be a black mass of gooey material that looked like living mud. For this unprecedented situation, most of the mercenaries were immediately frightened, and the top mercenary team maintained the last calm in fear.

"All fire! Beware of concealment! ”

In such a short period of time, many mercenaries were at a loss, but the top mercenary team quickly issued 2 orders to organize all the mercenaries and jointly target the mysterious team on the stairwell and the black mud. Due to the strength of the Mystic Warband's attacks and the stubbornness of the Black Mud, the mercenaries could only fire and prepare to retreat quickly to the lower floors.

The stairwells of the fierce battle could not withstand the constant attacks, and the mercenaries knew about these problems, and the members of the mysterious team were equally aware of them. When the stairwell collapsed, both the mercenaries and the mysterious team quickly evacuated, except for the black mud, which was crushed by the falling rubble.

Since the stairwells up and down the floors have collapsed, the mysterious battle separated by several floors naturally cannot jump down, or continue to attack, but can only take a detour and rush down through other stairwells. For these things, the top mercenary team that has experienced a hundred battles naturally would not be surprised, so they led the team to another stairwell.

"Where did those mysterious people come from? And black mud! "In the process of hurrying, one of the top mercenary team leaders asked questions to his henchmen. However, no one could answer. These phenomena are present in all mercenary teams, and everyone is terrified of the unknown, but refuses to admit it.

When most of the mercenaries left the collapsed stairwell, only a few mercenaries were left alone, and just as they were about to leave, black mud overflowed from the rubble, and before the lone mercenary could react, he wrapped it up. The mercenary who realized it later was reduced to an immobile mud statue when he was left alone, and lost his precious life one after another.

The black mud wrapped around the lone mercenary was the absorption that wanted to enter the life, but at the most critical moment, the black mud had not had time to recover, and the mysterious team in the building arrived at the scene. Holding guns that resemble ******, the members of the Mystic Team lock onto their targets and unleash unique liquid ammunition that quickly melts the black mud.

With a loud bang, the stairwell from the 31st floor to the 37th floor collapsed.

On the 21st floor of the building of Shuguang Technology Group Co., Ltd., in the all-round steel safe room hidden in the highest office, Yan Ming's ears moved slightly, and he said to the Liang brothers and sisters: "Did you hear that? The sound of the collapse...... It doesn't matter if you don't hear it, there are low-frequency vibrations...... Coming from the upper floors, it is believed that a fierce battle caused the collapse of one of the stairwells, causing a fault between the upper and lower stairs. ”

"So it seems that the radiation of the particle blast wave changes you a lot." Hearing this, Liang Tingwei commented, and just when he wanted to continue, Yan Ming said to himself: "Now is not the best time, let's continue to wait...... Don't let the outside world find out we're here. ”

"Alright! Since you say so......"

At the same time, the mercenaries on the 34th floor of the building were once again confronted by members of the mysterious warband. The mercenaries were soon killed and wounded, as this was no ordinary encounter, but an ambush that the mysterious team had been preparing for. At the beginning, the mercenaries were running down another stairwell to the 35th floor when members of the mysterious team appeared from below the stairwell and started the first battle. Then, when the mercenaries wanted to break through, they found that there were also members of the mysterious team on the 35th floor, and they were in a dilemma.
