"Feng Carp guys, it is precisely because I am in this realm that I have brought a lot of threats and obstacles to the genius of their family, that they are bent on killing me, very good, wait for my brother to break through all the entrances, and in the future, at the battle meeting, I will torture and kill those wizards of your family!" Yang Di grinded his teeth fiercely, this incident, he was very angry, and he was determined to take revenge.

"Hehe, little thief, you have quite an idea, but that ancient secret realm, for thousands of years, has countless mysterious legends, if you have the opportunity, you must fight for it!" Ye Shenyu glanced at him, and at the same time agreed with Yang Di's efforts to compete for the top spot in the realm.

Even if you don't breathe this way, the interests behind that kind of honor have made countless monks crazy for thousands of years.

"Now I'll stabilize the foundation and break through the Evil Realm, and then we'll try to get out and surprise those guys!" Yang Di said solemnly.

"You really should surprise those guys!" Ye Shenyu nodded, a chill flashing in his fiery red eyes.

The realm of those seven people is very high, even if she is now, she is not as good as her, but it is not without a chance to fight.

With the improvement of her cultivation, especially after condensing the terrifying ability of the debut fetus, her control of the Qinglian Jade Treasure will definitely not be the same.

The Dao Fetus can make the monk become the carrier of the Dao, not only the operation of the Dao is becoming smoother and more powerful, but even the power of urging treasures has multiplied a lot.

After Yang Di took a pill that had been prepared a long time ago, he took a sip of the spiritual base liquid, sat down, and began to use the power of medicine to impact the higher level.

Ye Shenyu sat aside, got dressed, and calmed down, took out a jade slip, and comprehended the demon clan Taoism.

The profound Dao method there is an important inheritance of the demon clan, and in the past, she could not start studying it until she had at least reached the realm of enlightenment.

But now, with a Dao fetus, it has become possible to comprehend in advance, and Ye Shenyu also has to master more powerful means as soon as possible, and give those guys a little color...

......

In the empty dark area under the water, after waiting anxiously for two days, Feng Carp and the others finally received feedback from Ji Kaixiu.

The expert group found by Ji Kaixiu has determined the location of the seven people through many cutting-edge instruments, and the results are shocking, they are about 3,700 meters deep from the ground.

After the seven people fell into the underground river, they actually drifted with the tide and drifted into such a deep underground water layer, which is really jaw-dropping.

Moreover, the area where the underground lake is located is covered with very thick rock formations, and with such a deep distance, it is almost impossible to drill this rescue method.

This is no more than diamond oil, at the very least, the hole that is punched down needs to meet the needs of a person's body to drill out.

According to the assessment of many experts, even the most powerful mechanical means of today will take more than a year.

But by that time, I'm afraid that the people in the underground lake would have run out of oil and run out of lights, so this kind of countermeasure will not work at all.

Another way is to start from the source and put high-strength cables, but the strategy, after several rounds of sonic exploration, has been reluctantly rejected.

Because of the dark river entrance of the tomb, if you want to go to the underground lake, you need to travel more than 100 kilometers, and it is difficult to operate just the winding and complicated dark river passage along the way.

In the end, with the help of geological experts, Ji Kaixiu decided to take another approach - to find a natural crack in the vicinity and start from it.

Generally speaking, there is almost no direct passage between the rock formations above the underground lake, otherwise Feng Li and the others would not be trapped under the underground water, they had previously looked for it, and there was indeed no other exit from the huge underground lake around them.

However, there is no direct connection, but it is a good way to put together a series of connections, for example, between two ground cracks, although it is a dead end, but if it is only a few tens of meters apart, or even hundreds of meters, it can be artificially opened.

In this way, as long as several suitable cracks at different depths are found through high-tech exploration methods, and artificially excavated one by one, the fastest speed can reach the rock layer at a depth of more than 3,700 meters.

This is much easier than vertical drilling, and the geological expert group has selected 39 of the most suitable natural fractures between the upper rock layers of the underground lake through precise exploration methods, and is ready to artificially connect them in series.

The cracks in many places are indeed not wide enough, but they can be artificially widened, and the whole project is expected to take about half a month.

This is already very impressive, and even extreme measures such as high-energy laser cutters and miniature directional bombs, Ji Kaixiu has found reads;.

Otherwise, it will take at least four or five months to carry out this huge project with the help of ordinary coal excavation and mining engineering groups.

Ji Kaixiu's meaning is to hope that the seven people of Fengli must persevere, and the group must support at least 15 days, of course, the longer it lasts, the better, after all, such a difficult engineering project may not be able to guarantee that there will be no unexpected delays at all.

"No problem!"

Hearing that there is still more than half a month, he and others will be able to escape from this ghost place, the seven phoenix carp people are underwater, trembling with excitement, through the signal of the submersible, swearing that it will definitely last for fifteen days.

Now the oxygen in that cave is estimated to be able to breathe for three or four days, but with the cultivation of the seven of them, it will not be a problem to hold on for more than ten days.

"Okay, I hope you are all safe, and besides, you can wait patiently and quietly these days, and soon we may not be able to contact each other for the time being. Ji Kaixiu truthfully told the seven people one thing in the small speaker.

"Why is this?" the phoenix carp frowned in the water droplets, waiting quietly was nothing to their monks, but staying in such a ghost place, in the dark, was really a great blow to people's will.

Now they can hear the voices of the outside world, they all feel more cordial, during this period, if they can always know the progress of the above project, I think they will always maintain strong energy, but if the contact is suddenly broken, this will really make people feel furious and restless.

Moreover, if something goes wrong in the middle, then the seven of them have to call the earth and the earth unspiritual, and that kind of atmosphere is terrible to think about.

"These underwater search instruments were purchased by the daughter of the Ning family at their own expense, and they are currently going to deploy all the other submersibles in the dark river near the underground lake to other places to continue to search for Yang Di and the others, and I have no right to intervene in this matter. Ji Kaixiu smiled bitterly.

He also advised him on this matter, after all, once he lost contact with the people in the underground lake, it meant that the probability of variables would increase greatly, and it would be difficult to negotiate when encountering problems.

However, the pearl of the commander's family, as well as the eldest lady of the Ning family, and the others couldn't listen to it at all, and they wanted to continue to use submersibles to search other areas, and they didn't plan to leave it for the seven people in the underground lake.

Remember to read it: convenient for next time, or.
