Hou Yu escaped into the sand, and this kind of terrain was not too easy for him, a soil mouse.

The sand layer is soft, after thousands of years of precipitation, the thickness of the underground sand layer here has exceeded five zhang, this is still because it is on the edge of the patella desert, the deeper you go, the deeper the sand layer will be, and the more serious the desertification.

Yuan Shangyuan's method is that it can drill through the sand layer, but it cannot penetrate the soil layer below.

When Hou Yu escaped to the bottom of the sand layer, he could clearly feel the breath of water, which was several times richer than the normal sand layer, which fully showed that there was a more humid soil layer under the sand layer.

He left Yuan Shangyuan's Dharma phase clone and continued to dive, his body quickly melting into the soil, discerning the strength of the water along the way, searching for the breath left by the undead.

A few days later, he felt that there was not the slightest trace of the activity of the undead creatures, so he sent a message to Yuan Shangyuan through the Fa Xiang, preparing to dive deeper; But he wasn't sure if he would lose contact after diving, so he needed to be informed in advance to avoid misunderstandings among the people above.

After getting ready, he continued to retreat into the depths, wanting to know the location of this underground dark river, and soon, at a depth of more than ten zhang, he found a dark river, the undercurrent was surging, and the amount of water was very large.

Ten days later, he drilled out of the sand, and the whole process was uneventful, confirming the existence of the underground river and eliminating the speculation that the undead relied on the activities of the dark river.

The only result is that a clear line of the underground river of Longxugou is drawn, which is very different from what is marked on the map; But then the question arises, since there are no traces of undead activities here, why does Yu Zhengxing want them to come here to investigate?

With such doubts, the team returned to Loulan City after going out to inspect for nearly four months. "What's going on? How many days are you going to gather for discussion?"

After Hou Yu handed over the outline of the trip, including the direction of the dark river, Yu Zhengxing did not see him, but said that it would be strange to hold a meeting after the other teams returned.

Nan Xiangye pulled him aside, everyone is familiar with this mission, so there is no need to hide some things.

"Senior brother, there is one thing I have to remind you of, among the monks that Uncle Yu transferred from the Yanmen this time, they all have a common characteristic....

Seeing him spitting and spitting, Hou Yu was very funny, "What characteristics? It's still worth the fuss and secrecy?"

Nanxiang Wild God is mysterious, "This transfer, in addition to the fact that every one of them is a disciple who is close to Senior Uncle, there is also a characteristic that everyone is very rich!"

Hou Yu's eyes narrowed, "Who said I was rich? Poor, this broken sect hasn't made an offering to Lao Tzu since I came in!"

Nan Xiangye smiled, "Senior brother, it's useless for you and me to cry poor, and I won't lend you spirit stones; I mean, this time Uncle Yu brought us people here, probably to draw blood, after all, everyone has been mixing well outside over the years, and their hands are also loose, like Senior Brother, you are the pirate leader in Lizhihai, the gold and silver mountains.....

Hou Yu didn't admit it, "Which king-eight-faint transmission of this? Nothing like that! But is this true or is it a private speculation?"

Nan Xiangye, "Guess what's the guess, there are rumors in private from the senior brother who has been here for many years, and they don't want to say the specifics....

Hou Yu was very resolute, "I won't dig out a spirit stone anyway, as for you..." Nan Xiangye, "Senior brother doesn't pay it, and I don't pay it either!"

The two reached an offensive and defensive alliance and vowed to fight for the spirit stone in their pockets, the only thing that puzzled them was, what excuse would Yu Zhengxing use? Hou Yu was curious.

During the period of recuperation in Loulan, he began to exercise his [Thunder Fire Forging Gold Body]. Because he can generate thunder on his own, the speed is very fast, and it only took more than ten days for the membrane skin Lei Du to complete the cultivation, and now he has begun to enter the stage of golden bone thunder forging, and with his feelings, he can probably complete it within the year.

This is the guarantee of his own strength, his own realm is enough, and he has a natural Dao body, a Yuan Magnetic Dao body, so it is very easy to get started.

The next forging of the Three Treasures may be the challenge, but that is a matter of the Jindan realm, not something that should be considered now.

This is not just an increase in the thickness of the skin, but an overall improvement in the resistance of the spell

High, when the membrane skin of the body is covered by a layer of thunder, the special suppression of the five elements by the thunder will reduce a part of the magic power.

There is no end to cultivation, and if you don't retreat, you will advance, and on the path you choose, you will still unswervingly move forward step by step, sometimes fast, sometimes slow, but no matter what, the forward momentum remains the same.

A month later, the team that went out on a mission gradually returned to the city, and in the absence of a new mission, the monks of Loulan City gathered together rarely.

Finally, the high-ranking monks composed of several Jin Dan convened everyone to have a special meeting, and all the monks who came to serve in Loulan were invited, regardless of the level of the realm.

Yu Zhengxing, as the chief official of the Loulan direction, presided over the meeting.

There were no superfluous words, just hung the pictures on the wall, a total of ten maps, pieced together, including the map of the underground dark river of Longxugou that the team got this time.

"In the Jacula Desert, there is a dark river, in history it is the snow river thousands of years ago, the years have changed, the land has become desertified, and the great river that originally flowed on the ground turned underground, which is the current dark river."

Yu Zhengxing pointed to the pictures on the wall, "These ten pictures are all drawn by you who went underground during this mission, they are authentic and credible, and connecting the ten pictures together is the direction of the Snow River in the territory of Guloulan.

You can imagine how majestic this former snow-capped river is if you add the dark rivers in other regions, which lie across the Jacularis Desert and divide this land into two worlds, and around the snowy river is the legendary snowy river loop, which is rich and beautiful, and rich in products."

With a longing on his face, he waved his hand and said, "It is precisely because of the existence of the Snow River that there are so many ancient civilizations here in history, and the northwest is not a place full of wind and sand, but a paradise for people to live and work in peace and contentment.

However, the wind and sand have destroyed all this, although the cultivation realm has not found out the cause of desert erosion and the disappearance of the snow river until now, but at least we know that if we want to fundamentally change all this in the northwest, we can only start from the original snow river, the current dark river!"

Yu Zhengxing's eyes flashed with wonder, "We practitioners pay the most attention to timing, when we come and go, heaven and earth work together, and we are not free to transport the common beings; In the past, every generation of Loulan Town Guardian monks had a feeling that the existence of the dark river might be the key to our human race breaking the situation in the northwest, but the timing was not right, and acting rashly would cause anger and resentment, but it would be a bad thing.

But now, after the revival of the spirit of the splendid great 1,700 years ago, it has once again come to the critical edge of the great changes in heaven and earth, and I think the time has come!"
