Wuding Kaishan is a mythical story, saying that King Qin Hui wanted to destroy the Shu Kingdom, but there was no passage between Qin and Shu at that time, so he took advantage of the local greed of the King of Shu and let people carve five huge stone oxen to give the King of Shu, saying that the stone ox could dig out gold. The greedy and ignorant King of Shu believed it, so he sent five strong men to pave the way and dragged the stone ox from Qin back to Chengdu in Shu.

On the way back, the five men saw a giant snake burrowing into the cave, so they tried to pull out the giant snake and get rid of it, but the whole mountain was collapsed, and the five strong men were crushed by the mountain. However, the road they built was used by the Qin State, and the Qin general Sima Cuo followed the road they opened up, advanced all the way, destroyed the Shu State and the Ba State, and seized this country of abundance, the Qin State greatly increased, laying a solid foundation for the later Qin Shi Huang to unify the six countries.

This is the origin of this tragic and brave poem in Li Bai's "Shu Dao Difficulty". This legend is recorded in the Chronicles of the King of Shu in the "Huayang National Chronicles" and the "Historical Records". Of course, it is impossible to open up a Shu road by relying only on five people, but it can also be vaguely seen from it that it took many ancestors to build the plank road back then.

Gu Fengchun sighed with emotion, what Tang Maiqiu and the six people built was not a plank road, but a "rope road", a way to climb the sky by relying on mountaineering ropes. The glowing temple at the top of the hill is lighting the way for the warriors who are struggling to build the road. It's just that Gu Fengchun knows very well that under that light is not glory and gain, but death and danger.

This night, Gu Fengchun couldn't sleep after tossing and turning. Because from time to time a piece or two of gravel would fall from the top of the rock wall, although the camp was far away from the rock wall, the stones falling from the sky could still cause a lot of movement. Every time he heard that sound, Gu Fengchun's heart tightened, worried that it was a big living person who fell down. If you fall from such a high place, let alone a human, even a Transformer will have to go back to the factory to re-smelt.

It's just that Gu Fengchun doesn't know that he is not the only one who can't sleep. This night, Chen Si and Qin Chuan both tossed and turned, each with their own hearts. When it was dawn, Chen Si got out of the camp as soon as possible, and talked to Tang Maiqiu and the others above on the communicator.

Tang Maiqiu's voice was obviously a little hoarse, and after a night of non-stop work, they were already exhausted to death. But their results are also quite impressive, and so far, they have reached a height of almost 2,300 meters! It will only take two hours at most, and they will be able to open the road to the top of the mountain.

Chen Si was very excited. This data is obviously a great encouragement for him. Tang Maiqiu, they have already created a miracle.

Chen Si immediately released the news. This news is also exciting news for the players. They all geared up to climb the path that had been carved out by the warriors last night. But Chen Si told everyone that the team's departure time was set for two hours later, and he wanted to give Tang Maiqiu and the others plenty of time to rest. During this period of time, Chen Si asked all the team members to leave all the unnecessary things on the camp below, only to be able to travel lightly, reduce the weight of the body, the weight of each climbing rope is an upper limit, after calculation, Chen Si stipulates that on a rope, there can only be two people who climb at the same time, and the limit cannot exceed three, otherwise the pitons may fall off, and the impact force that a climbing rope can withstand is only 5 tons, if two people fall, they can barely be pulled, If there are three people, it is a bit mysterious, and if there are more than three people, then you have to say Amitabha.

These team members are all good climbers, so they naturally understand that Chen Si's requirements are for the sake of their life safety. So they also try to lighten their own loads. Climbing a 3,000-meter rock wall is a crazy thing to think about, not to mention the physical strength required. In addition to the expensive nutritional tablets and water, everyone didn't even bring canned meat, and their clothes were thrown away, except for weapons, they refused to give up everything they could throw away. Some of the team members have gone so far as to cut their beards and hair that have grown over the past few days much shorter. These weights are insignificant, but a single straw can crush a camel when it is weak.

After tidying up, the team members began to eat, and this meal, they ate as much as their bodies could to meet the limits of their bodies, so that their bodies had enough energy to cope with the climb. Everyone knew that if they didn't have the physical strength, they wouldn't be able to climb up at all. If you can't climb up, it's naturally difficult to climb down, and no one can save you if you stay in mid-air, and in the end it's a dead end.

Some also wore goggles. This goggle can adjust a person's field of vision, similar to a telescope, when looking at things, it can bring distant places closer, and when looking down, this goggle can make everyone less afraid of high altitudes. Looking at the high morale, Chen Si was very pleased.

Everyone also tried their best to show that they were the best troops, and the little rock wall was not a problem. It's just that many people found a place and kept smoking, this small action let Chen Si know that in fact, many of them were still very nervous in their hearts, but they didn't show it.

Every twenty minutes, Chen Si would contact Tang Maiqiu to determine the progress of the above work. Tang Maiqiu's voice was very short and tired, but their news still made Chen Si very happy. Tang Maiqiu no longer knows how many bits and batteries the electric drill in his hand has been replaced, he only knows that there is not much left of the pitons, but it should be enough. This made him feel relieved. From last night to now, these six people have only rested for an hour, and this hour is still hanging in the air and swinging on the leather strip tied to the buckle hole of the climbing rope, I really can't imagine how these six people can sleep.

Tang Maiqiu turned his head to look at Hao Sandao and Bazi's team on both sides, their speed was much slower than before. It seems that there is not much power left.

"Need a break?" Tang Maiqiu consulted everyone, and added, "We still have four hours to go, and they will not climb the mountain until two hours later, and by the time they reach our section, it will be at least two hours later." "Tang Maiqiu's math is very good, and he calculates the marching speed of the players very accurately.
