Chen Hui and Zhou qiuchu both have the accomplishments of the world at this time. Chen Hui is currently in the fifth level of cultivation, and Zhou qiuchu is in the fourth level of cultivation. These two levels of cultivation are equal. They can not only move forward, but also lift Qi and lighten body.

Hearing Chen Hui's words, Zhou qiuchu nodded silently, indicating that he had mastered the way to lift Qi and lighten his body.

Before Zhou qiuchu came to this world, when he was in the world he came to, although he was not a man of practice, he was able to master the ability of wind blade. Although he came to this world and changed his way, he became a man of practice in this world, but for Zhou qiuchu, there was no difference.

Even if there was a difference, it was not very big, which was the main reason why Zhou qiuchu's cultivation progressed so fast.

Chen Hui and Zhou qiuchu, who had already been able to see things in the dark, didn't need to light up torches. They lifted themselves up and walked slowly into the crater where the meteorite fell and burned violently.

This crater is not straight up and down, but has a certain slope. As Chen Hui and Zhou qiuchu slowly move forward, they look around the whole crater.

The lower you go, the smaller the crater.

Moreover, because the crater has been formed for a long time, when it rains, rain will flow in, and the ground is somewhat wet.

The more Chen Hui and Zhou qiuchu went inside, the wetter the ground became.

"If you use metal aura to feel it, can you feel the metal around you?" Zhou qiuchu said at this time.

Chen Hui nodded, extended the metal aura in his body, and then slowly shook his head, saying: "no, the metal content around is extremely rare, and what I can sense is not iron metal, but only by looking for it."

Zhou qiuchu nodded silently and continued to walk forward with Chen Hui.

At this time, Chen Hui and Zhou qiuchu have been on the road for more than half of the journey. With their ability to see things in the dark, that is, their night vision ability, they can already see the innermost situation.

The innermost space to be reduced to the smallest is an irregular circular passage about three meters in diameter.

However, at the end of the passage, there is obviously more space, which seems to be very large. Chen Hui and Zhou qiuchu can't see clearly the situation inside the space, but can only see the situation of the narrowest passage about three meters away.

It wasn't long before Chen Hui and Zhou qiuchu came to the end of the passage formed by the crater. The space behind the end of the passage is a circular space with a diameter of about 10 meters, presenting a spherical shape.

In other words, even the ground is concave, not flat.

At this time, there is a lot of water on the ground below the depression, presumably because of the rain pouring in all the year round.

Zhou qiuchu looked at Chen Hui and asked, "is there any way to solve this situation?"

Chen Hui nodded and said nothing more. The water in his body was aura. He established a connection with the rainwater pouring in, and then controlled the rainwater to flow in the opposite direction, that is, towards the channel. This was completely the case of water flowing to a higher place.

However, Chen Hui didn't control the water column to go up all the time. Instead, he stuck to the channel wall and waited until the water below dried up to form ice.

Zhou qiuchu immediately went into the pit to check the situation and said: "there was also an explosion under the condition of fierce combustion, which led to the emergence of the spherical space. Because the explosion and combustion were carried out at the same time, the surrounding area did not collapse directly, but it was more solid, just like the situation of firing bricks at high temperature."

At this time, Chen Hui had already gone down to the bottom, listening to Zhou qiuchu's observation and checking around.

"Look here!" Zhou qiuchu pointed to the place that was flooded by rain before and said.

Chen Hui and Zhou qiuchu look at the place where Zhou qiuchu points out, and the place between them is dotted with golden yellow. Chen Hui and Zhou qiuchu look closely and find that it is some golden metal inlaid on the wall.

"Gold?" Chen Hui asked suspiciously.

Zhou qiuchu simply picked out a piece of golden metal the size of his thumb, then pinched it a few times, bit it with his teeth, and said, "no, gold is soft. Although these metals are golden, they are quite hard!"

After a pause, Zhou qiuchu said: "this kind of golden metal should be left by the meteorite explosion. The metal that can survive in the explosion and intense combustion is absolutely superior metal material. It is possible that we have never seen this kind of metal in the world we come to. We should collect it first."

With these words, Zhou qiuchu began to collect scattered golden metals in this area.

The gold metal in this area is about the size of the thumb cover, with a dozen pieces, no more than 20 pieces at most.

This kind of metal is very hard, and it is not integrated with the strong wall formed by fierce combustion. It only needs to be pulled lightly and it will fall down. But if there is no external force, this kind of metal will not fall down on the wall.

Zhou qiuchu is collecting these metals, and Chen Hui naturally wants to look around.

Soon, Chen Hui also found a place with these scattered metals. However, the metal blocks in this area are smaller, which is about the size of the little finger cover. The number is quite large, as many as 50 or 60 pieces.

After Zhou qiuchu collected the metal in that area, he also began to look for it in other places. Chen Hui took off his clothes, put the collected metal in it, then made a bag and threw it to Zhou qiuchu.

After collecting, Zhou qiuchu put the collected metal pieces into Chen Hui's clothes, wrapped them up, and then continued to search with them.

About a few hours later, Chen Hui and Zhou qiuchu thoroughly searched the whole area and found that there were countless golden and hard metals.

Zhou qiuchu weighed the weight and said, "it's almost fifty or sixty Jin!"

"Let's go!" Chen Hui took over the burden of Zhou qiuchu's clothes and said, "these should be enough. If not, we can mix some other metals to find the best materials. This is the end of the journey. I'll take you back to the King City of Mu nationality!"

Zhou qiuchu nodded and said nothing more. He followed Chen Hui out of the crater and back to the ground.

At this time, it was past noon.

Chen Hui and Zhou qiuchu did not continue to search for superior materials. Instead, they went directly to the Mu nationality area. Their destination, of course, was the King City of Mu nationality.

"These metals are very strong, and I don't know if they can be melted at the current smelting level." Zhou qiuchu said on the way back.

"You have to inform the fire clan and ask them to send someone to try it." Chen Hui replied.
