The movement of the transformation powerhouses led by the city lord of Rock City was also very fast, and the group of expeditionary soldiers that Fengyun was responsible for transporting could enter the ground, and they also transported the remaining expeditionary force over.

Maybe it was because they thought that the way the expeditionary force soldiers transported by Fengyun was good, and the rest of the expeditionary force soldiers also did the same, all jumped from the sky and went directly into the ground.

Then some of the shapeshifting powerhouses who were in charge of transporting the soldiers of the expeditionary force did the same.

In the end, only Fengyun, Wukong, the City Lord of Rock City, and Shi Fang were left who had not entered the underground river.

It's not that they have changed their minds and don't want to go underground, but they want to stay and check it out to make sure they don't leave any traces to trace, and they were very impressed by the pigs and rats who were responsible for leading the way for the cannibal barbarians.

They don't want to see the enemy confirm their movements because of some avoidable detail, and although this is a small possibility, it should be taken seriously as long as it exists.

The three people left behind all have good insight, and even Goku was left behind not because of indiscriminate numbers, but because it can really help.

In fact, when it comes to removing traces, Wukong is even more experienced than Fengyun and the others.

Before it obtained the golden monkey provided by Fengyun, it had lived in the soul bone space for a long time, and the living environment in the soul bone space was surprisingly poor, and if it was not careful, it could be killed.

In this sinister and abnormal environment, if you want to survive, in addition to having good strength, it is more important to know how to hide yourself.

And it is particularly important to hide yourself, remove the traces you have left behind, and prevent the enemy from discovering them.

Wukong has been able to survive in the soul bone space until now, and seems to be living quite well, which can be seen in his ability to conceal his whereabouts.

Even if the environment it is in now is different from the internal space of the soul storage bone, many truths can be figured out, and it can also be useful.

In fact, Goku's performance is indeed good, and in the process of clearing the traces that may be left behind, it has achieved a lot, although it is done by first telling Fengyun about his findings, and then ventilating Yun's mouth to say it, but its contribution is indelible.

"City Lord Yin, senior Shi Fang, if you can trust me, you will go in first, and I will be responsible for sealing the entrance to the cave and hiding it. “

After confirming that all the traces left behind had been removed, the three of them and one monkey re-entered the passage connecting the underground river, and Fengyun offered to put the finishing touches on the complete sweep.

The City Lord of Rock City and Shi Fang glanced at each other and said in unison, "Of course we can trust you. Here we go. ”

Before the words fell, they took the same method as the soldiers of the expeditionary force, and went directly into the passage without touching the ground.

If you look closely, you can even see that they didn't even touch the passage itself once in the process of entering the underground river through the passage.

"Wukong, you can go down too. ”

Fengyun watched the city lord of Rock City and Shi Fang enter the passage, and motioned for Wukong to follow as well.

"Yes, master. ”

Wukong answered, and turned into a golden light and disappeared into the passage.

Fengyun flew to the top of the passage with the blue dragon, and did not immediately make a move, but made observations, and soon found that the soldiers of the expeditionary force still left some traces in the process of entering the underground dark river, mainly from the trophies they carried.

Although the soldiers of the expeditionary force had been as careful as possible in the process of entering the underground, after they entered the territory of the cannibal barbarians this time, they had gained a lot because they had destroyed many cannibal barbarian nests one after another, and it was still a little inconvenient to carry.

Fengyun's gaze didn't linger long on the opening of the passage, and quickly moved away, looking around.

In his opinion, in order to make the sweeping work perfect, it is definitely not as simple as blocking the passage mouth, but also taking into account the surrounding environment and harmonizing with the surrounding environment.

Otherwise, it will be like putting a red patch on a pair of green pants with holes, and no matter how skilled the repair is, it will look very eye-catching.

Fengyun thought for a while, and seemed to have an idea, the blue dragon under his feet quickly shrank, and finally turned into a blue light and disappeared into his body, and he happened to come to the top of the passage opening at this time, and jumped directly into it.

However, he did not follow the passage directly into the underground river like those who had entered it before, but as soon as he entered the passage, he reached out with a hand and grabbed the wall of the passage.

Almost as soon as his finger was inserted into the wall of the passage, a change was noticed outside the passage mouth, and the earth began to move as if it were alive, gathering towards the passage mouth.

And that's not all, the plants that grow near the entrance of the passage also move, and after the earth seals the mouth of the passage, they move over, either in front of it, or directly on top of it.

In the process, they continue to change, and soon become in tune with their surroundings, just like they grew in the first place.

On top of that, Fengyun is also very detail-oriented.

Not only was grass transplanted on the soil that blocked the entrance to the passage, but the surface of the surface was eroded by the water and weathered, and the traces of weathering were vividly simulated, achieving perfect unity with the rest of the surrounding area.

To this extent, even the most critical people can't find any fault.

Of course, thanks to Fengyun's perception, even if the passage has been sealed with mud, he can still "see" the situation outside, so as to make targeted adjustments.

After the adjustment was completed, Fengyun went through it again with his perception, and found that there were no flaws left, so he began to rush towards the underground dark river, preparing to join the city lord of Rock City and the others.

However, in the process of approaching the underground river, the speed seemed to be relatively slow, and it took about ten minutes before finally entering the underground river.

It makes sense that he was so slow, because in the process, he also did one thing and sealed the passage entirely.

If someone were to look at him, they would see that he had just passed by, and the earth was pouring out of the walls of the passage, completely filling the passage space, and this process continued until he left the passage.

In the process of filling the passage with the clay sculpture, Fengyun was also meticulous, with the help of his sense, he made the soil filled in the passage exactly the same as the soil outside the passage, so that it disappeared in a real sense, not just blocked.
