499 S-grade Rock Wall

Liu Yan looked at the newly acquired S-grade earth attribute skill, Rock Wall.

Liu Yan had some experience in using secret art. Although the attribute skills comprehended through secret art were only of S-grade, they were much more powerful than ordinary S-grade skills.

After all, those skills were comprehended through the secret art. At the same time, it was also enhanced by secret art, so its power was naturally stronger.

For example, the Prison of Giant Trees that he had learned from the Wood Secret Art was an S-grade skill, but it was powerful. It could trap powerful beasts above its level, which was of great help to Liu Yan.

Fire Secret Art had upgraded his S-grade Flame Control to the SS-grade Flame Blast. It had now become Liu Yan's strongest attack skill.

Liu Yan couldn't help but look forward to the S-grade skill, Rock Wall, that he had comprehended from Earth Secret Art.

Immediately, Liu Yan checked the effects of the Rock Wall.

Rock Wall

Grade: S

Effect: Rapidly condenses a large amount of earth attribute energy in the surroundings to form a huge Rock Wall. It can be used for defense and attack! ]

The effect of the Rock Wall was similar to what Liu Yan had predicted. It was indeed an earth attribute defensive skill.

However, to Liu Yan's surprise, the Rock Wall could not only be used for defense but also for attack.

Since no one was around, Liu Yan decided to try it. He activated his S-grade skill, Rock Wall.

Under Liu Yan's control, a wall appeared.

The wall was a few meters wide and could help a small team block attack.

However, Liu Yan could also feel that he had not deliberately enlarged the Rock Wall. He had just condensed it casually.

If he intentionally increased its size, it could probably be large.

The ability to condense was determined by Liu Yan's mastery of the earth attribute and his strength.

Liu Yan's current strength was not weak. He had also mastered the SS-grade Earth Secret Art. Naturally, he could form a large Rock Wall.

He had not tested it out yet, but Liu Yan guessed it would not be difficult to create a 100-meter-wide wall to help the team block the attacks.

Immediately, Liu Yan tried out the defensive capabilities of the Rock Wall.

Liu Yan immediately stepped forward and punched out, but nothing happened when his fist landed on the Rock Wall.

Seeing this, Liu Yan was a little surprised.

Liu Yan did not wear any equipment, nor did he use any enhancement skills. He just relied on his physical strength.

However, Liu Yan had already used all the strength in his body.

Without relying on equipment or skills to enhance his strength, Liu Yan's strength was already extremely terrifying. His strength attribute was over 20,000 points, which was extremely powerful.

However, even such an attack did not affect the Rock Wall. It was clear that the Rock Wall's defense was superb.

Immediately, Liu Yan used his S-grade skill, Power of the Earth.

Instantly, Liu Yan's entire aura changed, and his body obtained a terrifying boost in strength.

Liu Yan punched out with all his might, landing on the Rock Wall.

Many cracks appeared on the Rock Wall but did not completely shatter.

Upon seeing this, Liu Yan immediately gained a general understanding of the Rock Wall.

To be able to withstand Liu Yan's punch with the Power of Earth, this Rock Wall's defensive ability was already extremely terrifying.

Of all the awakened ones on the fifth level of the Tower, the number of awakened ones who could break through the Rock Wall could be counted on one hand.

The scariest thing about the Rock Wall was that as long as it did not shatter, Liu Yan could control the earth and attribute energy around him to recover the wall.

Under Liu Yan's control, the cracks that had just appeared on the rock were repaired.

It meant that Liu Yan's punch was in vain.

In the future, if the enemy were to face this Rock Wall, they would have to use terrifying power to destroy it.

Otherwise, the Rock Wall would continue to absorb the surrounding earth attribute energy and recover quickly. It would not be able to be broken at all.

This mechanism of automatically absorbing earth attribute energy to strengthen itself was similar to the S-grade Prison of Giant Trees.

After a round of testing, Liu Yan was satisfied.

Although the Rock Wall was an S-grade skill, its power was already close to an SS-grade skill.

This Rock Wall covered Liu Yan's shortcomings.

Previously, Liu Yan did not have any good defensive skills.

When faced with an enemy's attack, one could rely on speed to dodge or use terrifying physical strength to resist.

However, while it was still fine against ordinary attacks, it was somewhat helpless against powerful attacks.

It was like the Silver Moon Secret Skill used by the European Federation team captain, Hans Wilson, and the other experts. It was powerful and completely surpassed their level. Liu Yan could not take it head-on and could only dodge.

However, if it were the current Liu Yan, he could use the Rock Wall to defend himself.

The Rock Wall's defensive power was terrifying. Even if it could not defend against the Silver Moon Secret Skill, it could at least weaken its power by a lot, allowing Liu Yan to take it head-on.

After all, the Silver Moon Secret Skill was a powerful S-grade combination skill. It would consume all the physical strength and energy of the experts from the European Federation team in one go. Its power was terrifying.

It was a terrifying skill that was activated by the full strength of seven experts. The current Liu Yan could rely on his strength to face it head-on, which was already extremely terrifying.

Apart from defending oneself, this Rock Wall could be used flexibly. It could also defend the team members. It had a wide range of uses.

Liu Yan could even use Rock Wall to attack. Its effects were versatile, and Liu Yan wanted to try it out when he had the opportunity.

Immediately after, Liu Yan also withdrew Rock Wall and planned to leave.

Liu Yan extracted the earth attribute core, allowing him to obtain an SS-grade Earth Secret Art and an S-grade defensive skill, Rock Wall.

However, there was no way he could gain anything by staying here, so Liu Yan naturally did not want to waste his time.

Immediately, Liu Yan stood up and left.

Outside the door, Ye Yifan, captain of the Red Star Empire team, was following Liu Yan's orders and personally guarding the place.

Initially, Liu Yan's order was for the Red Star Empire team to arrange for a few members of the Red Star Empire team to stand guard here and not let anyone else enter and disturb them.

However, how could Ye Yifan listen to Liu Yan's orders and arrange for the Red Star Empire team members to guard Liu Yan's door? It was too embarrassing. Ye Yifan might as well wait here by himself. He could also complete Liu Yan's orders and not have to face the Red Star Empire team members. That would be too embarrassing.
