This Zhu Lao, speaking of which is a legendary figure, has climbed snow-capped mountains and grasslands with Taizu, killed the devils, calmed down the civil strife, worshiped the generals, and ranked eleventh on the list of Chinese generals (author's note: the novelist said, apocryphal as Yuer).

However, Zhu Lao has always been indifferent to fame and fortune, has never participated in the factional dispute in his life, he loves to travel in the mountains and rivers, explore the secluded and seek songs, it is said that he and the famous Chinese geologist Li Zhonghua is a good brother, the two in China after the founding of the country, together to travel to every corner of the land of Jiuzhou. Moreover, he has a strong physique, is good at health preservation, and when he is over 100 years old, he looks like an old man of sixty or seventy years old, and he has a straightforward heart, and has the reputation of "Naughty General".

It's just that since Li Zhonghua's death, few people have heard of him, some people have rumored that he has passed away, some people say that he went to a deep mountain and old forest to live in seclusion to practice the way of immortality, and some people even say that he has become an immortal and has ascended, but only high-level people know that this old man has not stopped, but whenever there is any strange place, he will be there in person.

Therefore, Professor Ling, Professor Du and others did not feel strange at all about Zhu Lao appearing in the 10,000-meter sinkhole and going down to the pit with them.

To say that it is strange and amazing, that is, this wish for the elderly to be over 100 years old, it is really unbelievable that he still has this energy.

At this time, he looked full of red light, there were few wrinkles at the corners of his eyes, and the hair under the baseball cap was neither white nor black, but shiny black hair, which was even healthier than the hair of a young man.

Is this rejuvenation? After seeing Zhu Lao's appearance, everyone's hearts couldn't help but think like this.

Because a lot of equipment was lost in the second round of the pit, under the auspices of several professors, the five exploration teams redistributed the equipment, and the five exploration teams formed five squares and began to explore and sample the sinkhole.

The sinkhole below 1,200 meters is even bigger than the pit mouth above, with a long distance of more than 1,500 meters and a short distance of more than 1,070 meters.

As for the missing Ye Yishan and others, the military will send someone down to look for them, and the three people who are missing from the exploration team will not be added.

"Again, safety first. When you sample according to the norms, you must pay attention to safety, you are not allowed to act alone, every two people are a group, you can freely combine, today our goal is to go deep into a thousand meters. After Xiao Zihan divided the area and before the action, he convened everyone again for a mobilization meeting.

The slope is still very steep from 1,200 meters below 1,000 meters, between 60 and 70 degrees, but because of the vegetation and many potholes, it will not have much impact on climbing up and down.

However, there are many deep pits and deep depressions in the sinkhole, and it will be dangerous to accidentally fall into them, so safety must be emphasized.

The expedition team has their own set of criteria for collecting specimens, ranging from surface vegetation to ground soil, to shallow soil, deep soil, and surrounding water sources. Of course, the animals and ores that appear around are also important specimens.

Over the course of the day, cheers of triumph continued to be heard from the sinkholes, with single-celled organisms being collected, ores never seen before, rare herbs being collected, and so on.

As for the search for Ye Yishan and the other four missing students, soon after the competition of the five exploration teams began, the garrison troops sent a ten-person team down and went directly to the depths of the sinkhole to find them.

Xiao Zihan secretly told Zhou Tian that if something like this happened, it was estimated that the stationing of the special forces would be advanced, at most two to three days, and the first batch of soldiers of the special forces would arrive.

Zhou Tian didn't say anything about this, but just told her that after the first day of exploration, he would leave quietly, firstly to find Liu Jiayue, and secondly, to see what the hell the people behind the gang were doing.

Xiao Zihan didn't say much about this, after all, she already knew some of his magical skills, but just reminded him to pay attention to safety, and he had to rush back before the next day.

After finishing work for the day, Zhou Tian took side dishes and began to head to the depths of the sinkhole.

The reason why he didn't leave at the beginning of the exploration competition that day was not because he wanted to win glory for Qingda or anything like that, but because he had already gotten the results of the initial exploration from Professor Du and Xiao Zihan, after going deep into the sinkhole for five thousand meters, the air pressure below did not decrease but increased, almost equivalent to the pressure of entering the deep water, and the further down, the greater the air pressure, and the first batch of troops to enter could not go down when they went deep into the sinkhole for 5,500 meters, and several people were so oppressed that their ears bleed.

According to the number jù brought back by the first batch of troops, the experts deduced the more scientific number jù, and these numbers jù Zhou Tian got it from Xiao Zihan, according to his second calculation, the atmospheric pressure at the depth of the 5,500-meter sinkhole should be the strength oppression of the martial artist in the early stage of dark energy, and then every hundred meters forward, the increase in pressure is equivalent to the strength oppression of a small level of martial artist.

Under such circumstances, he believed that even a super powerhouse in the Yuan Force Realm would not be able to reach the deepest part of the sinkhole. Therefore, no matter how Ye Yishan and the others hide their strength, it is absolutely impossible to go down to the deepest part of the sinkhole.

And he firmly believes that the biggest secret of the sinkhole must be in the deepest part of the sinkhole.

And he also believed that whether it was Ye Yishan, Yue Xiaotang, or Xu Yajing, it was impossible for them to have the strength of the super powerhouses of the Yuanli Realm.

The super powerhouse of the Yuanli Realm has its own pride, how could he use such a way to enter the sinkhole to get something? The strength of these three people, with half a step of the Yuan Force Realm, is already the top of the sky.

Also, there was an exit to this sinkhole, and he didn't believe that these people could slip away under his nose. And even if they want to, they can't go, with a vertical distance of 1,200 meters, even if they are strong people in the Yuan Force Realm, they can't fly over, unless they have a flying spirit weapon or a spirit weapon flying sword, such as the Jade Qing Hairpin after he will refine it in the future.

But as far as he knew, in today's cultivation world, spiritual weapons were extremely rare, and flying spiritual weapons were even rarer. Don't look at those strong men of the Gang Qi Realm, the Yuan Force Realm, and the Condensation Realm standing in the air very chic, very fan, and very stylish, in fact, in addition to the great consumption of Gang Qi Yuan Force, there are also great restrictions in height.

It is impossible to say that they are flying, rather than staying in the air and gliding, and it is simply impossible to let them fly at an altitude of thousands of meters.
