In the real world, you have to be careful not to let ordinary people find out, and in the mission world, the contractor has no time to train, and in the dangerous mission world, the contractor does not dare to waste his mental power to train skills at will.

They all adjusted their state to the best at any time to deal with all kinds of emergencies, so although the cost of the training room was very expensive, Lu Chen never dared not use it.

The need for do-it-yourself training, plus potential points are difficult to obtain, and there is also the need for survival points to rent training space, which makes it not as convenient as buying powerful equipment directly.

A good piece of equipment can be put into battle just by taking a little time to familiarize yourself with it, and it doesn't need to be as troublesome as Lu Chen, but cumbersome also has the benefit of cumbersomeness.

Low-level skills are indeed useless, but as soon as the skill level reaches the high level, the power of these skills has changed dramatically, a C-level skill is much more powerful than a C-level equipment, and feeling the C-level skills in his body, Lu Chen is extremely satisfied.

At this time, he also wanted to buy a few more C-level skills to upgrade them to the full level, so that his strength would increase even stronger.

But after thinking about it, Lu Chen still gave up this plan, he still had to train to buy skills, Lu Chen didn't have enough time, and he still had B-level skills to train.

Although he had upgraded all his C-level skills to the full level within a month, Lu Chen understood that that was just the beginning, the power of B-level skills was several times that of C-level, but correspondingly, the difficulty of improving was also several times that of C-level skills, and Lu Chen felt that the rest of the time was enough to upgrade a B-level skill.

What's more, Lu Chen still has his own self-created skills to study.

Things were not as Lu Chen expected, and then Lu Chen was really busy, since the Earth Splitting Technique had a bit of stagnation since it fused the skill talent of positive and negative magnetic imprints, and Lu Chen couldn't do it even if he wanted to use potential points to upgrade such skills.

After all, the function of the potential point is to make the complete skill directly imprinted into the contractor's mind, and this skill created by Lu Chen, Lu Chen, doesn't know what its complete form is. How to instill space in Lu Chen, so this skill, Lu Chen can only ponder slowly.

Although the B-level skills have not stagnated, after Lu Chen's training, he can feel the growth of proficiency, but these growth is still a lot worse than the proficiency that B-level skills need to upgrade.

The first month of entering the tour space. Lu Chen can be said to be smooth sailing, but in the second month, Lu Chen fell into a bottleneck, first his self-created skills came to a standstill, and then it took a whole month for B-level skills to be upgraded to one level, which is not all skills upgraded to one level, but only the earth element was upgraded to level five.

At this time, Lu Chen understood the difficulty of upgrading B-level skills, which made Lu Chen a little depressed. It takes a month to upgrade to the first level, and judging from the situation that the higher the skill level, the more difficult it is to upgrade, even if there is no bottleneck, it will take several years for Lu Chen's B-level skills to be upgraded to the full level, which is still in the training room that can speed up the training, and Lu Chen himself also has the talent to accelerate training.

Skills training is really not a simple thing.

But it's not all bad, although the self-created earth splitting technique Lu Chen has fallen into a bottleneck, but when Lu Chen is tinkering with it. I also researched another self-created skill, which is relatively simple. Looking at the wasteland in front of him, Lu Chen's mind moved, and a large number of dirt hands stretched out from the ground, thinking that the sky had grabbed it.

This is the hand of clay researched by Lu Chen, and it has two forms, one is the form that relies on quantity to win. A large number of dirt palms, not much larger than human palms, swayed on the ground, searching for humans on the ground.

This skill is a bondage skill created by Lu Chen, although such a dirt hand is a little smaller, but after catching the enemy, Lu Chen can make them turn into stone immediately. Moreover, Lu Chen also combined the talent of petrification with these palm forces.

If you are caught by such a palm, as long as the enemy does not break free, the part of your body that is captured will be petrified.

Although such a small palm does not have much power, it does not have much effect on the contractor with too high strength, but they are numerous, and with Lu Chen's spiritual power now, if he shoots with all his strength, he can summon hundreds of such palms in one go.

At the same time, Lu Chen did not let this skill deal with powerful people, this skill was designed by Lu Chen in order to deal with a large number of enemies.

And its second form is prepared to deal with powerful people, looking at the many palms in front of him, Lu Chen's mind moved, and two huge human palms with a foot of two or three meters slapped together fiercely in a place in front of Lu Chen's eyes from two directions, with a whistling wind, bringing a rumbling sound.

Judging from the prestige of these two palms, ordinary contractors would be directly slapped to death in the middle, and Lu Chen added some knowledge of his research on the Earth Splitting Technique.

For example, there is a rune in the palm of the two palms, which is the magnetic imprint, and the imprint of the two palms is positive and negative, which makes the speed of Lu Chen's rock palm much faster, and ordinary contractors can't avoid it at all.

The two forms of this Dirt Palm are designed to deal with enemies with a large number of people and powerful enemies, and they can be said to be good skills.

Lu Chen was still quite satisfied with the creation of this skill, but now there was no happy expression on his face.

Now he was thinking about something else, and at this time, Lu Chen understood that he needed to make a choice to study.

Now that sixty days have passed in this training space, there are only forty days left for Lu Chen, which is not enough time for Lu Chen to upgrade all his skills to the full level, so Lu Chen needs to choose whether to choose to upgrade a single skill or study all the skills together.

After thinking about it for a few hours, Lu Chen slowly made up his mind, instead of making the level of each skill not high, it was better to upgrade one skill alone.

As for the upgraded skills, Lu Chen also slowly had an idea, Earth Element Summoning, the first skill that Lu Chen has, this skill has a deep meaning to Lu Chen, and at the same time, it has helped Lu Chen overcome a lot of difficulties, and now he can only upgrade one skill, Lu Chen chose it without hesitation.

In the last thirty days of training, the earth element was already at the sixth level, and now Lu Chen was about to upgrade to the top level.

Thereafter. Lu Chen had been training the earth element, summoning it, observing its structure, directing it to attack, thinking about the way to fight with it in his mind, and time passed slowly. Soon, forty days later, it was time for Lu Chen to leave this space.

In the past forty days, Lu Chen has been training non-stop, and he doesn't dare to relax at all, but after forty days, Lu Chen's earth element is only level six, and he has only been upgraded by one level, which makes Lu Chen a little depressed.

However, when he reached the sixth level, Lu Chen was no longer polite. Immediately upgraded the earth element with potential points, so that it was upgraded to level seven, and at this moment, Lu Chen hesitated.

The seventh-level earth element is already strong enough, but now Lu Chen has a talent aura on his body, as long as it is an earth-based skill, as long as it is an earth-based skill used by Lu Chen, Lu Chen can make them add two more levels. This is a very rebellious talent, and it lives up to the title of Lu Chen's soil master.

Now the seventh-level earth elemental already has a ninth-level situation. If Lu Chen is promoted to another level, this earth element will have the power of the original full level, which makes Lu Chen's heart tremble a little, and he is considering whether to waste potential points to upgrade, although Lu Chen has a lot of potential points, but Lu Chen relies on skills to eat. He also has a lot of skills to improve, and he really doesn't dare to waste potential points.

Now there is no bottleneck in the improvement of the earth element, if Lu Chen has time, he can directly exercise the earth element to the eighth level, and there is no need to waste potential points. Potential points are not used when breaking through bottlenecks, which does feel a bit wasteful.

But after thinking about it for a while, Lu Chen still chose to use it, the earth element has always been one of Lu Chen's most powerful means, and it is the same now, upgrading the earth element has greatly improved Lu Chen's strength.

No matter how precious the potential point is, it has to have a life flower, and if you can improve your strength, Lu Chen still does not hesitate to waste some resources.

With the upgrade of the earth element, the earth element skill icon on Lu Chen's interface has undergone earth-shaking changes, after taking a look at the above introduction, after reading it, the originally indifferent Lu Chen has been stunned, the full-level earth element is too perverted.

At this time, Lu Chen found that the strength of the earth element was about the same as that of him now, and if he fought alone, Lu Chen didn't know if he could deal with the earth element.

The earth element that was added to the full level made Lu Chen very satisfied, and with its guards, Lu Chen knew that he had a layer of security in the mission space.

The upgrading of the earth element is a good thing, but Lu Chen also has troubles, his earth splitting technique has not made any progress for forty days, which makes Lu Chen a little suspicious if he has done something wrong.

In addition to these, everything else is okay, as soon as he entered the space, Lu Chen devoured the purchased Captain America's shield to the liquid metal, which is worthy of being called the hardest metal, Lu Chen's liquid metal devoured a full ninety days before the broken shield was devoured.

At this point, Lu Chen's magnetic talent also has a place to play, liquid metal can defend and attack, and can be used as Lu Chen's weapon.

In addition to these, what surprised Lu Chen the most was that his Rock Palm had a new change, it was also a self-created skill, and the Earth Splitting Technique had not improved, but this skill Lu Chen had already studied the third change.

This change is specially prepared for the strong, and it is precisely the third change that the Palm of the Rock has researched, which makes Lu Chen have some confidence in his self-created skills, otherwise, it is really difficult to say whether Lu Chen can persist in continuous failures.

In the past 100 days, although Lu Chen's basic attributes have not changed, his skills are almost cultivated, all the C-level skills have been upgraded to the full level, and the earth element has the power of the original full level, and he has developed a self-created skill.

These are Lu Chen's gains in the past 100 days, but now Lu Chen is going out, and with a flash of light, Lu Chen once again came to Nightmare Square.

Looking at the way people came and went in Nightmare Square, Lu Chen suddenly felt a little uncomfortable, living alone in the training space for a hundred days, Lu Chen was used to being alone.

The monotonous cultivation was really uncomfortable at the beginning, but I have to say that people are a group of creatures with strong adaptability, and after being lonely for a long time, Lu Chen has already adapted to loneliness.

After standing in place for a long time, Lu Chen slowly changed his mentality, although there were many people coming and going in Nightmare Square, and there were some curious Lu Chen who was standing motionless in place, but Lu Chen's whole body was wrapped in a black robe, and they didn't know Lu Chen, but no one came to interfere with Lu Chen, so that Lu Chen also got a sense of peace in the midst of people coming and going.

Lu Chen, who recovered, turned on the communication function of the Nightmare Mark for the first time, because he had to train, Lu Chen turned off the communication function before entering, this was for fear of being disturbed, and at the same time, the training room was indeed too boring, and Lu Chen was afraid that he would not be able to withstand the temptation, so he ran out halfway, so he simply turned off the communication function of the Nightmare Mark, and spent a hundred days quietly.

At this time, Lu Chen turned on the communication function in order to contact the poisonous snake and see how the tracking props she contacted were doing.

However, something happened that Lu Chen didn't expect, as his communication equipment was turned on, a large number of call applications appeared in Lu Chen's communication equipment, which made Lu Chen startled and didn't understand what was going on.

Although he didn't understand what was going on, he couldn't use force in this nightmare space, so Lu Chen was very calm and browsed the messages one by one in the same place.

After reading for a long time, Lu Chen read all the information, there was the most information about the poisonous snake, and most of the other people he knew sent him some messages, but the most were sent by the contractor Lu Chen didn't know.

After thinking about it for a while, Lu Chen put aside the matter of information first, and sent a message to the poisonous snake first, asking the poisonous snake to go to the tavern to find him, and Lu Chen also went to the tavern to sit first.

Anyway, Lu Chen's most important thing now is his sister, the others can be put aside, his sister's matter must be solved first, and at the same time, find the poisonous snake first, Lu Chen can also get some news from the poisonous snake to see what happened and why so many people are looking for him.

didn't let Lu Chen wait too long, after receiving his news, the poisonous snake quickly came from outside, and after looking in the tavern for a while, she relied on the contact between the team members and sat down opposite Lu Chen.

However, seeing her appearance, Lu Chen frowned, the poisonous snake at this time was the same as Lu Chen, and it was covered in a black robe, which made Lu Chen know in his heart what had happened, otherwise, the poisonous snake would not be so hidden.

It's just that these can be said later, and without waiting for the poisonous snake to speak, Lu Chen took the lead in asking: "I want the props you are looking for, have you bought them?" (To be continued......)
