But the crowd shook their heads. By this time they were very tired. It stands to reason that rest is very much needed. However, they also know that a short rest will not help, if they can't resist the feeling of fatigue in the body and rest, that short rest time will not only not have a good effect, but because the nerves are loosened, they will obviously feel all kinds of discomfort in the body, and when the time comes to work again, it will affect the performance. Now their limbs are numb, and they have to work mechanically, and although it is hard, they are used to it, but once they relax, they have to spend a lot of time adjusting to this state. When the time comes, it will inevitably affect the team's forward plan.

That's the last thing people want. So all five of them rejected Tang Maiqiu's proposal.

Tang Maiqiu smiled bitterly. I had to continue to drive the pitons into the rock wall, then install the ropes, and climb up step by step. He had forgotten how many times he had repeated this action.

But by repeating this action, you can turn this cliff into a smooth path. Tang Maiqiu thought secretly in his heart.

"Old Tang, look at the left, what is that." Hao Sandao on the side coughed, stopped what he was doing, and said to Tang Maiqiu.

Tang Maiqiu hurriedly turned his head to look and saw a dark cloud floating in the distance above the sky on the left. If you look closely, it is a dense group of black birds vibrating their wings and flying towards them!

"It's a black bird!" Tang Maiqiu's face changed a little. They have seen the power of this black bird. In addition to their huge attack ability, the most terrible thing is that they carry the virus that can make people replicate themselves. They have already seen the power of these viruses. Although the attack power of those replicants is not very strong, they can turn people into walking corpse-like existences, which is the greatest lethality.

"What should I do?" Xiao Zhonghua was also a little anxious.

"Wait and see!" Tang Maiqiu looked around, they came here to open the way, in addition to the tools for mountaineering, the only weapons on their bodies were electric drills and ice-breaking axes in their hands, these things were okay with these black birds, and it was better to save money if they wanted to fight with others. And everyone is at a height of several thousand meters, even if they want to escape, they don't know which direction to flee. He was not able to do anything else except wait and see what happened, but Tang Maiqiu reported the unfortunate news to Chen Si as soon as possible.

Chen Si was stunned for a moment, and also gave instructions to Tang Maiqiu and the others not to act rashly, and asked everyone to suspend their activities. This black bird may not have come for these people.

Chen Si's expectations are good. These black birds didn't come for Tang Maiqiu and the others, in fact, they flew a few hundred meters high. Approaching the top of the mountain, they swooped down on the mountain walls, as if they had their food on them, and the black birds hovered there for less than ten minutes, and then flew back in groups in the direction they had come from, and the group was only a false alarm.

But it's also a false alarm. Let Tang Maiqiu be very vigilant. He was fully aware that this mountain wall, which did not seem to be very dangerous, might also be a dangerous existence. So he asked Chen Si to prepare the firepower to come up, just in case.

Chen Si was deeply impressed by Tang Maiqiu's proposal. In fact, he was already pondering the intention of these black birds to suddenly come to this rock wall for a while and then disperse with a bang. It's just that he didn't know the essentials for a while, he thought about it, and felt that it was better to send a few people up to protect the few people who opened the way above, and then he discussed it with Qin Chuan, and one person from each side, Zhou Xiaoyi and Honeysuckle, with a few guns and a lot of ammunition on their backs, became the first batch of climbers.

The two of them had a general intention of comparing strength, only buckled a simple safety ring, and looked forward to the rope, and climbed up quickly in the recess on the rock wall that was smashed open by the ice-breaking axe, as fast as the wind, and in less than five minutes, the two of them had already climbed the first climbing rope. The climbing speed of the first climbing rope did not distinguish between the two of them, but after changing lanes, the power of honeysuckle began to skyrocket, leaving Zhou Xiaoyi behind at once. At this time, the people under the mountain wall have to use telescopes to see their figures clearly.

Zhou Xiaoyi chased after him for a while, and found that this honeysuckle was really good, and he no longer wanted to catch up, so he slowed down his speed and climbed up slowly. Honeysuckle saw that Zhou Xiaoyi was no longer competing with her, and slowly adjusted to a normal speed, and when it reached a place of more than a thousand meters, the speed of both of them slowed down, at this height, no one dared to be careless, and when they looked down, they had to be dizzy for a long time, who would dare to be strong! It took about forty minutes or so for the two of them to catch up with the few people who were opening the way on it. This speed is actually several times faster than that of ordinary team members. Neither of them climbed up with the help of a ring of safety buckles, and they climbed up with their bare hands, purely physical work, which made Tang Maiqiu and others admire it very much.

With the protection of the two of them with guns, Tang Maiqiu and the others felt a little more courageous, and the speed of progress began to speed up again. At this time, Chen Si also glanced at the time, and then said to the team members who were already ready to go: "Okay, let's go too!" ”

A total of four ropeways are opened, which means that at least four people can advance on each climb, but normally eight people can climb at the same time. This is a fairly safe carrying capacity, so in order to save time, Chen Si climbs at the same time every time he intercepts the climbing rope, but the second team member can not follow up until the first team member climbs to a height of almost 200 meters or more. Wait until a team member is replaced with another rope before a new team member can be added.

Chen Si asked all the team members to remember the rules he had set. And it is stipulated that if there is a team member who is weak and cannot climb up for a while, the successor must not rush forward, and he will not be able to climb up until he recovers! This is to ensure that each rope has enough strength to carry the team forward. If something happens to the rope, the damage to the team will be huge! Chen Si had to be cautious. So spending a little more time in exchange for the safety of the team is actually a very cost-effective thing. Besides, the open road above has not been fully opened, and there is still some time to buffer them.

Chen Si looked at the team members who were slowly climbing towards the mountain wall, his mood fluctuated, and he thought silently in his heart: "It has been 1,500 years since the last time I was here. How many times has the world changed in the past 1,500 years? Chen Si smiled bitterly and turned his head to look at Qin Chuan not far away.
