The reason why Jinling creatures like to build their bases underground is because of their concealment.

Although it's easy to catch a turtle by mistake when they meet a powerful enemy when they set up a base underground, it's not difficult for them.

Because as long as all the things they do secretly are exposed, it is inevitable that they will be attacked by a group, because no one wants to become their research material.

Therefore, concealment is greater than safety for them.

To a certain extent, the native powers can escape, but this method is not omnipotent. The powerful consumption generated by itself, not to mention, will be over once discovered by the native powers of the other party.

Because the essence of hiding is not to make the body become virtual and overlap with the soil, but to separate the soil by the strong control of the soil, so that when you move in the soil and rock, you will act as if you are underwater.

However, this process is very dangerous.

If found by the enemy, as long as the other side uses the same tactics to control the soil or rock, you have to use double strength to break through, and often without breaking through, you are trapped underground.

Even if you are found by fire system and water system, you will be dead after your position is determined.

The fire system can directly heat the soil, and the water system can penetrate into every hole. As long as people are more skillful, they can come up with ways to deal with this situation.

Therefore, although Chu Feng had a rune, he did not dare to use it.

This kind of small skill can be used to deal with ordinary people who have no knowledge. Of course, it can be used to deal with terrible monsters such as Jinling creatures. That's to kill yourself.

However, he has another simple way.

"Listen to the sign!"

Chu Feng drew a ground listening sign in the void to confirm the general location of the other side's base.

In what he "heard", most of the underground is composed of entities, but not far away, that is, the underground of those buildings, there are a lot of gaps.

Those blank places are in order, like orderly rooms, which should be the basement of Jinling biology.

There are also some disordered places, which should be the caves developed by Jinling biology.

Then, he began to use Yuanfu space to collect some of the soil under his feet, forming a cave.

That's his way.

The space of Yuan mansion is very large. Although the things that can be collected by opening the entrance each time are limited, and a certain amount of vitality will be consumed, with the improvement of strength, this consumption has been ignored by Chu Feng.

For him, the consumption of collecting less than 10 cubic meters at a time is negligible.

Of course, if it exceeds the limit, even if 15 cubic meters are charged each time, the consumption will be tripled.

Moreover, if the object of collection is a whole, then if you want to separate the whole, the consumption will also soar.

For example, if a huge stone is separated, the front of each square meter will consume 1% of Chu Feng's vitality. That is to say, as long as the section exceeds 100 square meters, Chu Feng will directly exhaust his vitality.

In this way, Chu Feng continued to dig the ground, soil and rock into space.

He also conveniently added a camouflage to the top to prevent it from being found.

Just as he dived more than 10 meters, he suddenly stopped collecting.

"The underground rock has become a whole. It seems that it can only be separated."

The essence of soil is the result of individual and combination, but many rocks are connected into one. Chu Feng now meets the rock of one.

If you collect it directly, it will cost him too much.

Therefore, Chu Feng took out a short sword, and then used his innate sword Qi to cut it.

Although his sword of death is powerful, it only does great damage to life and little damage to the entity. However, since he has collected so many good things, how can he not prepare a spare weapon for himself?

The short sword in his hand was forged with the mouthpiece of the insect emperor. Its hardness is comparable to that of the blood drinking sword, but its growth is a little worse.

But at this stage, it is enough.

The sharpness of the short sword and the sharpness of the inborn sword Qi form a two meter long sword awn. Cutting rocks is like cutting tofu.

With Chu Feng once again cut down a piece of rock revenue yuan house, his eyes suddenly appeared red phosphorescence.

These red phosphorescence is like a red flame, blooming a red glow, let Chu Feng almost as a red gem.

In contact with the air, the red light gradually faded down.

When the red light disappeared, there were only some dark red stones left on the ground.

"Shouldn't it be the vein of Youlan magic gold near here? How can there be the ore of ChiYan gold? Besides, there are many rivers and lakes near Nandu, so this kind of thing should not appear. "Chu Feng quickly recognized the origin of these red stones, and there were some surprises in his doubts. "But anyway, this thing is a surprise to me. The skill of Youlan magic gold is very high, and the ChiYan gold corresponding to Youlan magic gold is much easier to develop, and can be directly forged into a magic weapon."

The dark blue magic gold is flexible and fits with life. It can be used to make mechanical prostheses or cast some soft weapons, but it's too violent to make swords.

ChiYan gold is strong and slightly flexible, which is a good material for casting sharp weapons.

It was also a surprise for Chu Feng to find the ore vein of ChiYan fine gold here.

"Anyway, the vein is here. We can't run away. We can't lose the big from the small."

Chu Feng took a deep breath and forced himself to bear the idea of mining a large amount of pure gold from ChiYan, "and now the time for drastic changes in the world is short, and many ore veins have not been fully formed. If the mining is too severe, it will cause great loss to the ore veins, as long as the mining is enough."

After the drastic change of heaven and earth, the change of the world is a gradual process.

Just as organisms need to grow and transmute, veins also have a process of growth, that is, the process of absorbing the power of veins and then turning into special minerals.

Once the excavation is over done, the process will be interrupted directly.

If you want to produce more powerful treasures here, don't even think about it.

Of course, there is also a reason that Chu Feng's forging speed is limited. Even if he wants to do his best, with his current strength, it takes a certain amount of time to forge ChiYan gold, and he can't afford to waste it.

What's more, not everyone can use the best equipment made of ChiYan gold.

It is better to wait until the strength is strong, so that mass production can be considered.

Now the most important thing for him is to improve his own strength.

He has to do a lot of things, we must have enough strength to achieve.
