As soon as Mo Fei came up from the tunnel below, he immediately began to organize his men and prepare to explore.

One team was ready to go to the tunnel to explore, and then a little bit of digging, the excavated soil was poured directly into the dark river, while the other team was preparing a raft, and Mo Fei was ready to try where the dark river could flow in the dark river.

Of course, Mo Fei will not explore the direction of the Dark River, he will only explore the location of the passage of the Dark River under the oasis, and out of the desert area after the oasis, Mo Fei will not explore.

The excavation team was quickly organized, and after comparing the location of the dark river and the passage between Mo Fei and the tribal warriors, a vertical passage was soon excavated above the tunnel.

This passage was dug very wide, which allowed the tribal warriors to enter the construction project, a large amount of soil was dug out and poured directly into the dark river, and the raft was also being made, in order to be able to train in the dark river, this time Mo Fei personally supervised, and finally made a raft that was strong enough to carry several golden-armored beasts without sinking.

The tunnel is still being explored, but the soil is so strong that the wooden shovels are almost useless, and the result is that it is impossible to dig quickly.

Mo Fei had already brought 10 tribal warriors to explore the dark river, and the tribal warriors had selected a team of 10 swimmers after training to swim in the pond that Mo Fei had dug in the ground.

After getting on the raft and preparing all the tools, Mo Fei and the others also began to row towards the direction of the oasis with all their might, and the direction of the countercurrent was towards the center of the oasis. The springs must be over there, too, and only then will there be a water supply for the oasis to take shape and consolidate in the desert.

Although the water flow in the other direction does not know where it leads. But Mo Fei had probably guessed that the various tribes lived underground. And their drinking water is collected underground, although it is very small, but if there is a water supply, and these water sources are flowing from the oases, but because of the distance, a large part of it is lost in the desert.

Mo Fei set off with 10 tribal warriors, and under the burning of torches, he walked backwards along the passage little by little, deepening as the distance deepened. Mo Fei felt like they were moving upwards.

"Is the spring on the ground?" Mo Fei thought to himself.

In the direction of the river, although Mo Fei didn't see anything, Mo Fei also guessed that it might be flowing deeper below.

"Boss, shall we rest for a while?" After 2 hours of gliding, even the rotation of the 10 tribal warriors was a little exhausted, especially since they were all feeling a little depressed.

In the darkness deep underground, it is lit only by torches, and the dark environment is accompanied by constant paddling. They were tired and uncomfortable, and now they all want to go back to the surface.

"Put down the stones, let's rest." Mo Fei said to everyone.

In order to prevent the raft from being swept away silently, Mo Fei immediately let the tribal warriors lean towards the edge. At the same time, he used the Green Dragon Immortal Sword to leave traces on it.

"Boss, where are we going to explore?" A tribal warrior asked at Mo Fei.

They really don't want to stay in a dark underground environment, except that torches can illuminate the surrounding environment. Everywhere else, it was dark, and none of them had Mo Fei's ability to see in the dark.

"It's a stretch ahead. When the investigation is clear, go back. "Murphy doesn't return because they're scared, Murphy wants to be close to the heart of the oasis. Then he regains the power of his sword intent.

This time, Mo Fei gave the tribal warriors a full hour to rest, and an hour's rest was completely enough for these tribal warriors to recover their strength. After recovering his strength, the raft once again slid towards the depths of the oasis.

Murphy estimated the distance and direction, and while there was certainly a mistake, they were indeed heading towards the center of the oasis.

As the height rose little by little, Mo Fei's hands could touch the top of the passage, and such a distance let Mo Fei know that he was probably close to the center.

Buzzing!!!!

The sword spirit of the Green Dragon Immortal Sword suddenly trembled, and a trace of spiritual energy began to converge towards it, making sharp sword rays emanate from the sword body.

"Reiki?" Seeing this, Mo Fei immediately thought that they were already approaching the center of the oasis, otherwise how could the Green Dragon Immortal Sword absorb such a rich aura.

"Keep gliding forward." Mo Fei shouted at the crowd.

As the road ahead got closer and closer to the center, Mo Fei and the others had already changed from standing to sitting, and when they stood up, their heads had already reached the top of the rock above.

After continuing to move forward for a while, and it was really impossible to move forward, Mo Fei let everyone control the raft and stopped, and at the same time sat on the raft and quickly cultivated.

This time, Mo Fei was finally able to cultivate the power of sword intent, and as the aura was continuously absorbed into his body, Mo Fei felt that his strength was constantly improving, which was no longer recovering, but really improving.

"This time, it seems that it is going to be promoted to the 5th layer of the Blue Dragon Sword Technique." Mo Fei was overjoyed in his heart, and immediately accelerated his cultivation.

Seeing Mo Fei sitting on the raft and cultivating, the aura was constantly sucked into Mo Fei's body, and all the tribal warriors showed shocked looks, they didn't know what Mo Fei was doing, with the humans on the exiled planet after countless years of inheritance, their cultivation had long been lost, and all they had now was a strong physique.

After a day and a night of cultivation, Mo Fei still didn't move, although the tribal warriors were a little anxious, they still guarded the raft and Mo Fei, and they were all waiting for Mo Fei to wake up.

Three days passed quickly, and the tribal warriors almost suffered from anxiety, but seeing that Mo Fei's body was still glowing with aura, and at the same time, a large amount of aura was absorbed, which made them endure all kinds of anxious emotions and continue to wait.

In 5 days, when the tribal warriors were about to wake Mo Fei up, Mo Fei finally opened his eyes, and now Mo Fei felt that the power of the sword intent in his body had been greatly improved, and at this moment, even if he returned to the periphery of the oasis, he didn't have to worry about the aura being unable to absorb it, and the laws of this world had suppressed him.

"It's a pity that I can't fly out of outer space." Mo Fei thought as he felt the power of the sword intent in his body.

Although he didn't have the ability to break away from the exiled planet, Mo Fei could now use his sword qi to deal with alien beasts, which was much sharper than relying on brute force and swordsmanship to attack alien beasts before. (To be continued......)
