Duan Lei felt that the latter possibility was higher. They had already witnessed the powerful ability of the mastermind behind the scenes to create zombies at the prison base. They could even turn corpses with broken skulls into zombies. So, what was so strange about gathering zombies like a Zombie King?

　　That's why Li Chenzhou summoned everyone back. They did have a way to resist sniper rifles. It was a prop that Li Chenzhou redeemed from the mall. Its effect was to withstand three ranged attacks as long as it was worn.

　　Because Gray Bear and the others were wearing this, they dared to act as bait in front. Otherwise, knowing there were snipers lying in ambush, who would dare to easily run outside and show off?

　　Now that they were about to enter the zombie horde, there was no need to lure the snipers out anymore. After all, even if the snipers' positions were discovered in such a dense group of zombies, there would be no way to rush over immediately.

　　"Do we start killing directly from here, or go over there first?"

　　After Gray Bear and the others entered Dark Blood, Duan Lei asked, pointing to a spot on the map on the coffee table.

　　"Let's confirm it first!"

　　Li Chenzhou hesitated, then looked at Gray Bear and said.

　　The location Duan Lei pointed to was the area where Leopard and the others were.

　　Because they had previously analyzed that with the mastermind's scale of gathering zombies, plus their positions, their zombie horde would definitely come into contact with Leopard's zombie horde.

　　Once these two groups met, a conflict was inevitable. The final result would only be one of two: either one side would destroy the other, or one side would swallow the other. There was absolutely no way they could coexist peacefully.

　　Li Chenzhou's choice was also for Gray Bear. This guy had always aimed to kill Leopard. Now that things might have changed on Leopard's side, he naturally wanted to know the situation there. After all, the zombies that Li Yunshan and the others had turned into were also there.

　　"Okay! Then let's go along the Second Ring Road first!"

　　Duan Lei knew what Li Chenzhou meant, so he nodded.

　　Because the edge of the zombie horde was still a few hundred meters away from the Second Ring Road, the Second Ring Road was currently quite safe. Even scattered zombies couldn't be seen; they had all run to the zombie horde.

　　Humans are naturally fond of excitement, and zombies are just as fond of clustering together.

　　It wasn't far from here to the building where Leopard was, so they quickly arrived nearby. However, the endless zombie horde that had surrounded the building had long disappeared, and even Leopard and Li Yunshan were all gone without a trace.

　　The building where Leopard was located was actually on the edge of the Second Ring Road, which was the road that Li Chenzhou and the others had broken out of. At this time, the area around the building was clean and empty, and all the zombies had entered the Second Ring Road, just like everywhere else!

　　"Go take a look!"

　　Li Chenzhou pointed to the building where Leopard had been, because judging from the situation here, they couldn't analyze whether Leopard had been destroyed or swallowed by the mastermind.

　　Gray Bear also seemed a little nervous. He did hope Leopard would die, but he wanted to kill Leopard himself even more. What's more, Li Yunshan and the others were still by Leopard's side.

　　Arriving at the building where Leopard was, Li Chenzhou had Dark Blood stop at the entrance, and then he got out of the car with Gray Bear and entered the building.

　　Although there were no zombies here, it was Leopard's old lair after all. There might be an ambush, so Li Chenzhou didn't bring anyone else, just Gray Bear.

　　Because Gray Bear's Gale Step came with a stealth effect, even if there was an ambush, there would definitely be no problem leaving. In addition, this guy was very strong in reconnaissance, so it was definitely right to bring him along.

　　After the two entered the building, they immediately knocked and tapped in the building, making a lot of noise. However, apart from the noise they made, they didn't hear any other sound.

　　"Could it really be empty?"

　　Gray Bear said, then took the lead and walked towards the stairs.

　　Going all the way up, they quickly arrived at the top floor and stood in the position where Leopard had previously stood with Li Yunshan and the others, looking at the collapsed parapet wall on the roof.

　　"No obvious signs of battle!"

　　Gray Bear walked around the roof, looked around, and then returned to Li Chenzhou's side, standing on the parapet wall and looking at the Dark Blood below, saying:

　　"But, we still have to go down and take a look. Last time we were here, we exposed the existence of Death Howl, so Leopard shouldn't dare to swagger on the roof anymore!"

　　"Okay!"

　　Li Chenzhou nodded. Anyway, this aspect mainly depended on Gray Bear, so whatever he said was what it was.

　　Just as the two turned around to leave, Gray Bear inadvertently glanced at the collapsed parapet wall again. Before, they were all standing behind the back wall of the roof, but now, Gray Bear jumped onto the parapet wall, which was equivalent to changing the angle.

　　"Huh? Wait!"

　　With this glance, Gray Bear suddenly revealed a look of surprise, then quickly looked around, and even took out a telescope to look around carefully.

　　Li Chenzhou didn't know what had happened, so he had to wait on the side. After Gray Bear took a full three or four minutes to carefully observe the surroundings, he put down the telescope and sat casually on the parapet wall, with his legs dangling outside, casually looking around, and said softly:

　　"There are zombies watching us, in the fourth room from the left on the top floor of the building at three o'clock!"

　　"Zombies? Watching us?"

　　Li Chenzhou frowned, but he didn't look in that direction immediately. Instead, he leaned on the parapet wall and looked down, saying:

　　"How did you find out?"

　　"There's a mark that Captain made at the gap!"

　　Gray Bear was still looking down, and answered:

　　"It's using our special ops code, other people can't understand it, and if you're standing on the roof, you won't be able to see it at all because of the angle!"

　　"Li Yunshan?"

　　Li Chenzhou was shocked. The gap that Gray Bear was talking about was naturally the gap where the parapet wall had been knocked down. If the secret mark was made at that gap, then it meant that Li Yunshan had left that secret mark after he turned into a zombie, because Li Chenzhou and Gray Bear had personally seen the appearance of that gap.

　　"Yes!"

　　Although Gray Bear still pretended to be very casual, his tone was quite excited, and there was a look of ecstasy in his eyes.

　　Since Li Yunshan could leave a secret mark, it meant that although they had turned into zombies, they still retained their consciousness. This was definitely a huge surprise for Gray Bear.

　　Whether it was a zombie or something else, as long as Li Yunshan still had his own consciousness, he was still Gray Bear's captain, and most importantly, it also represented that Li Yunshan had not really died...
