After listening to Vivian's words, Lu Chen understood at that time that skills can be upgraded through training, and potential points can save the skills from the process of understanding.

At that time, Lu Chen did not express anything in the face of Vivian's sneer, but shrugged her shoulders and signaled her to continue talking. Lu Chen would not tell her trump card at will, especially in this dangerous space.

However, after listening to Vivian's explanation of the skills, Lu Chen had already made up his mind to learn skills, and at the same time he was ready for the skills training plan. He first worked hard to upgrade to level three, and then used the potential points to make the skills qualitatively change.

Looking at the messy ground around him, Lu Chen summarized infinitely. During these fifteen days, Lu Chen did not relax for a moment and was undergoing endless training. The monotonous repetition made Lu Chen mentally exhausted. The desolate wilderness and the pain of exhaustion of mental power made Lu Chen unbearable pain.

However, the threat of death hangs over Lu Chen's head, making him dare not relax at all. He understands that only by working hard can one survive, and only by working hard can he realize his wish.

The oppression above the head and the hope in the heart made Lu Chen not crushed. He withstood the pressure and completed the upgrade of level one to third level D skills in a very short time. Now it is time to gain.

As Lu Chen's potential points decreased, the five skills he bought on the street stalls, earthen walls, earthen pricks, gravity techniques, and mud armor techniques all underwent earth-shaking changes.

Skill name: Stone wall

Skill Level: Level D

Need: 24 points of spirit

Skill description: Consume 20 points of mental power in a place with soil (Note: Spirit is attribute value, mental power is mana, mental power = spirit × 10) Call out a stone wall to stand in front to resist the enemy's attack, release time of 1.5 seconds. The hardness and height of the stone wall depend on the releaser's mental power and skill level. The skill can be upgraded. Now it is level 4, the highest level is level 7.

Cooling time: None.

Skill name: Stone Armor

Skill Level: Level D

Need: 24 points of spirit

Skill description: Spend 20 points of mental power in a place with soil to recruit a stone armor to bless your friend. The release time is 1.5 seconds. The hardness and protection of the mud armor depend on the mental power and skill level of the releaser. The skill can be upgraded. Now it is level 4, the highest level is level 7.

Cooling time: 3 minutes.

Skill branch: Anti-gravity Technique, consumes 20 points of mental power, weakens the gravity of the specified item, release time for 1.5 seconds, reduces the intensity of gravity, and duration depend on the mental power and skill level of the releaser. Skills can be upgraded, now level 4, the highest level 7.

Cooling time: 3 minutes.

The first four of these five skills mainly change the material of the skill from ordinary soil to harder stone. This is indeed a drastic change. The last skill change made Lu Chen interested, and it actually changed from aggravated to weakening. This made Lu Chen unexpectedly.

However, such changes can make Lu Chen's combat methods more varied, which is not a bad thing. Lu Chen was happy and stopped paying attention.

Then Lu Chen focused on the two B-level skills. The power of these two is indeed stronger than other D-level skills, which is worthy of the level of B-level skills. However, upgrading is also extremely difficult. Lu Chen has no other way to do this. Only by practicing hard, he must train well at the end of the skill training space time. This is the core of his tactics.

However, Lu Chen's training is not just hard to practice. When he first came, it was because Lu Chen needed advanced skills. Now most of the skills tasks have been completed, the combat method has been initially formed, and the remaining two B-level skills have been cooled down for too long, so Lu Chen has free time, and now he is about to start practical training.

With Lu Chen's operation, some enemies slowly appeared in the space. When these enemies saw Lu Chen talking, they attacked him without saying a word. Seeing the enemy appearing, Lu Chen did not talk nonsense and released his skills to fight him.

For the remaining ten days, Lu Chen faced endless enemy attacks, and the enemy also changed from weak to strong. At the beginning, Lu Chen was a little busy. After all, he had no experience in fighting in a stable society before.

Fortunately, the enemies in this space are all illusory and disappear whenever they are about to attack Lu Chen.

This gave Lu Chen time to regroup. Lu Chen was also glad that he could come to this skill space to train. Otherwise, if he encountered an enemy in the mission space, his own rush would be the way to die, and the enemy would not give him time to reflect.

In the training space, Lu Chen slowly learned to fight, and became more skillful in releasing his skills, and he was able to seize some opportunities to make some impressive counterattacks.

Although the enemies set by Lu Chen gradually became stronger and more powerful, in the days that followed, Lu Chen became more and more relaxed, and his fighting style gradually took shape. When fighting against various enemies, Lu Chen became more and more skilled in his skills and knew what skills to put in the battle. Although all this still requires a practical test.

Another happy event was that when Lu Chen was about to leave the space, his two B-level skills finally reached level three. In response, Lu Chen couldn't wait to use two potential points to upgrade both skills to level four. In the next fifteen days, Lu Chen's first-level skills will cool down and release these two skills.

With the hard release and excellent talent, of course, what you need is the fast skill training in the first three levels. However, no matter how successful it is now. Although it took Lu Chen a lot of time, the attributes of these two skills after upgrading made Lu Chen understand that his expectations were not in vain. The upgraded two skills are worthy of the B level.

Earth elements:

Power: 38

System: 45

Agility: 14

The skill duration is 2 hours and the cooldown time is 3 hours.

Skill:

Petrochemical Body: The earth element is made of soil, and its life is increased by 200, it has no vital damage, and it is not attacked by vital damage. The damage of the sharp weapon is offset by 50%, and the damage of heavy weapons is increased by 20%. The earth element has no mental power. The charm of the spirit will be resisted. If it cannot resist, the earth element will be destroyed.

Gift from the earth: He was born from the earth and was protected by the earth. Fighting on the ground will offset 20% of the damage. At the same time, he was protected by the earth and increased his recovery by 200% in the ground, and his recovery speed after being buried underground is increased by 500%.

Earth shock: Earth element stomps the ground with its feet, causing shock waves to the surroundings, causing the enemy to dizzy for 2 seconds, and causing damage to the same force.

Earth Collision: The earth element rushes towards the enemy at an extremely fast speed, causing power × 2 damage to the enemy and stun the enemy for 2 seconds.

Skill name: Magnetic shield

Skill Level: Level B

Skill Requirements: 40 Points of Spirit

Skill description: consumes 80 points of mental power to form a magnetic spherical shield to protect oneself or friends from damage. It has extremely strong protection against energy attacks and physical attacks. It has doubled protection against metal weapons. The protection ability is proportional to the user's mental power. It lasts for 5 minutes and has a cooldown time of 20 minutes. This skill can be upgraded at the highest level of ten.

Special ability: The space under the magnetic shield is affected by distorted light from magnetic radiation, and will be invisible. The chance of being discovered by the enemy is determined by the perception and releaser perception and skill level. The odor and heat of the contractor will be hidden in the magnetic shield, which is even more difficult for human and enemy to observe. (Note: The magnetic shield can only affect the line of sight and is ineffective for sound propagation.)

Special abilities: Magnetic blast. After the protection of the magnetic shield is broken, it will release the magnetic impact to open everything around you and cause mental power × 2 damage to it. The releaser can also actively release it to push away the enemies around you.

After the upgrade, the earth element with such attributes can be compared with some veterans. It is not a loss to be a B-level skill. Although it has a slow speed weakness, the three-meter-high body makes his attack range huge. Coupled with Lu Chen's assistance, it can be regarded as an important combat power, which is also the core of Lu Chen's combat attack.

The magnetic shield is another core of Lu Chen. It mainly ensures that Lu Chen himself is safe. Lu Chen in stealth will be difficult to find. Even if he is discovered, the shield is in danger. When it is still in danger, it can also use magnetic blast to blow the enemy away, so that he can gain more time. With the cooperation of other skills, although Lu Chen is not necessarily an opponent of the veteran, he already has the power to fight.
