In the days that followed, Lu Chen practiced his flying skills while training his skills, and when he was resting, he would let the liquid metal devour the minerals he bought, and he was busy every day.

However, in this way, Lu Chen's life has also become fuller, and at this time, Lu Chen also feels the benefit of more time in the training space, which can not only make his skills more proficient, but also allow him to become familiar with the skills of flying, as well as increase the volume of liquid metal.

Opening the training space this time is completely worth the money for Lu Chen, and even worth the money.

In this way, more than ten days passed, on this day, in the barren sky of the training space, a person in a black robe flew freely in the air, this person was of course Lu Chen, in the unmanned training space, Lu Chen's flight had no scruples, up or down, rolling, turning, and acting very easily, from which it can be seen that he has mastered most of the skills of flying.

After more than ten days of hard training, Lu Chen is indeed very familiar with the skills of flying, although the speed of flight is not satisfactory, it is not as fast as controlling steel flight, but Lu Chen is also very satisfied, presumably with the promotion of magnetic control in the future, the speed of flight will be faster and faster.

After flying freely in the air for a while, Lu Chen landed on the ground from the air, and a silver stream of water flowed out of his black robe, it was liquid metal, liquid metal can be transformed into anything, in order to facilitate it, Lu Chen turned it into a vest and wore it under the black robe, which was very convenient for flying, and it was also very confusing, and more importantly, it also gave Lu Chen an extra layer of defense.

The liquid metal that flowed out gathered into a spherical shape, and at this time it was already the size of a basketball, and seeing its size, Lu Chen sighed slightly. Two weeks ago it was the size of a football, and it is now the size of a basketball. It's been growing too slowly.

And the reason for its slow growth is not that there are not enough materials for him to devour, there are still many materials that Lu Chen has acquired. It has now become a picky eater, it is not devouring a lot of things, and its growth rate has become very slow, which makes its growth rate much slower.

Seeing this, Lu Chen could only sigh, but he couldn't do anything, his performance like this showed that it was going to devour better metal, but Lu Chen had no more survival points, so he could only give up and continue to cultivate. Let's talk about it when there is a survival point, but its size can also help Lu Chen fight.

After releasing the liquid metal, Lu Chen released the skill Earth Thorn Technique he had trained here, and after so many days of training, coupled with the increase in potential points, Lu Chen's Earth Thorn Technique and Gravity Technique level had been raised to the full level.

With a wave of Lu Chen's hand, an earth thorn burst out of the barren land, instantly forming a giant earth thorn two meters high. This time, Lu Chen didn't chant the formation of the earth thorn, and Lu Chen, who had been upgraded to the full level, could already do it instantly.

It's just that although the release time is fast, the size of the earth thorns has only become a little larger, and the earth thorns have not increased. The stony thorns did not harden either, as if they had not been lifted too much.

It's just that this is really the case, in Lu Chen's eyes. When the giant earth spike was fully formed, it suddenly changed. The top of the spike suddenly became bifurcated, and several small spikes suddenly spawned diagonally on top of the original spike. Causes the thorns to resemble a tree.

This is the result of Lu Chen's efforts for dozens of days, the earth thorn that has been promoted to the full level, in addition to the shorter chanting skills, has a second change, this change makes Lu Chen's earth thorn, as long as it stabs someone, the damage to the enemy will become huge.

Imagine how much damage a person can be to a person if the earthen thorn that stabbed the body suddenly flies diagonally inside the body.

Lu Chen was very satisfied with this earth thorn, in addition to the earth thorn, Lu Chen's gravity technique also became very strong, this time Lu Chen chanted two spells slightly, and the full-level gravity technique still needed some time to release.

After chanting, an area in front of Lu Chen's eyes suddenly sank a little, that was the effect of gravity, Lu Chen pointed at it, and the stone that sank down in that area suddenly staggered up again, this is the mutation effect of gravity Buoyancy.

These two are the abilities that the gravity technique had before the full level, but the gravity or buoyancy released by Lu Chen at this time is much stronger than last time, and after Lu Chen upgraded to the full level, he comprehended a new ability.

As Lu Chen's mind moved, a small black dot suddenly appeared in the middle of the gravity technique, and with the appearance of the small black dot, a large amount of dirt and gravel in the gravity technique suddenly gathered in the direction of the small black dot, and then all gathered together in the direction of the small black dot, forming a small soil pit.

This is the ability that Lu Chen has obtained by upgrading to the full level, he can place a mark in the center of the gravity technique, and attract all the objects in the gravity technique area to move towards the mark, this ability does not seem to be strong, but it is very useful, with it, the enemy who is surrounded by the gravity technique will be more difficult to escape, gather together, and it is easier to be attacked by Lu Chen.

After Lu Chen experimented with these two skills, it didn't take long for Lu Chen to be ejected from the training space by a repulsive force and appeared in the nightmare hall, this is the time to come, after coming out, Lu Chen immediately looked at his nightmare mark, which clearly showed all the things that Lu Chen had now.

Under Lu Chen's watching, there are very few survival points and potential points in it, and the survival points are only a few hundred points, and Lu Chen's training time this time is not enough, it was originally not enough to upgrade the two skills to the full level, Lu Chen can only rely on the promotion effect of the potential points, and consume a lot of potential points to upgrade the two skills to the full level.

At this time, after the potential points have been consumed, there is only one point, and this survival point and potential point are not enough for Lu Chen to buy anything, after seeing his nightmare mark, Lu Chen shook his head, he didn't do anything, he returned to the real world, there is no survival point, it is useless to stay in the space, it is better to go back to the real world.

Although Lu Chen had spent a lot of time in the training space, it had only been about five or six days in the real world, and there had not been much change in the room except that it was a little dirty.

After coming out, Lu Chen couldn't help but contact the detective agency to check on his sister's situation, more than a month has passed now, and he hasn't found it yet, Lu Chen is already a little anxious, just do it if he wants to, Lu Chen picked up the phone in his hand and made a call over there.

……

A few minutes later, Lu Chen hung up the phone and frowned, this conversation was not very good, the detective office was very large, with the conditions provided by Lu Chen, they easily found the family that adopted Lu Chen's sister, but the family went abroad a few years ago, and they had not contacted China for a long time, and it was difficult to obtain information at this time.
