Ten long minutes later, Wren's body was filled with frenzied energy, his face flushed, and blood began to spill from his mouth and nose. The energy is saturated, and Wren is now like a balloon, blowing a little air into it, and the balloon will explode, in other words, Wren will explode and die.

The power of the flame of the lava crystals was still continuously pumping energy into his body, and there was no sign of weakening, Wren was sweating like rain, if he could look inside, he would find that all the meridians were expanding and bursting, and the blood vessels on the surface of the body were bursting up, and it looked like countless red earthworms climbing on Wren from a distance.

No, I can't hold on right away! Wren anxiously realized that the strength limit of his body was here, and in order to accommodate the energy of Xia Haihui, he could only expand the capacity of the balloon, which meant strengthening the body. After killing Liu Zhuang in the system novice mission, he gained a considerable amount of experience, jumping from level 4 to level 5. But the intensity of the fifth-level increase is a drop in the bucket in the face of the power of the sea tide.

Wren suddenly raised his head to the sky and spewed out a mouthful of blood arrows, which was a danger signal that his body had reached a critical point, and several blood vessels in his hands and feet were overwhelmed and exploded directly, and the pain that penetrated into his heart and bones gnawed at Wren's soul like ants. At this time, a golden symbol appeared in the heart of Wren's chest, this symbol was like a maple leaf, this maple leaf sank from the chest and dived into the heart, and suddenly the ground was blazing, Wren only felt a loud bang in his head, and his heart burst out with a heartbeat, and the broken internal organs and blood vessels of his body were like soldiers on the battlefield hearing the battle cry of the victorious general's charge, and his spirit was refreshed!

As soon as that maple leaf appeared, it dominated the whole situation as a king, and turned into a miniature black hole and frantically swallowed the power of fire. The power of the flame found its outlet like a flood from a dam bursting, and rushed to the heart. Originally, Wren was worried that the capacity of this maple leaf was too small, but when half an hour passed, the maple leaf still begged endlessly, and the energy of the lava crystal was infused so much, which only made the maple leaf a little brighter.

Another hour passed, and the organs in Wren's body returned to normal under the leadership of Maple Leaf, and the alien destroyer Flame Power was taken over by Maple Leaf alone, giving them a chance to breathe. Wren prayed over and over again, hoping that nothing would happen. By now, the torrent of energy transmitted by the lava crystals had significantly decreased, and at this rate, it would almost be absorbed in another ten minutes. And in the center of Wren's heart, the maple leaf rune slowly turned into a solid, and a crystal the size of a fingernail slowly rotated, which was the product of the black hole's absorption of countless flame powers.

The light in the maple leaf crystal was pervasive, and Wren could feel how terrifying the sum of the energy contained in it was, but he regretted to find that although this guy grew up in his heart, he had no right to command him, and this maple leaf was like the most slashing miser, not pulling out a hair.

After absorbing the last bit of energy from the lava crystal, Wren opened his eyes. He only felt that the hot air around him had become extremely refreshing, his eyes were bright and energetic, his clothes were burned by the fire, but there was no trace of scars on his **** body. Wren moved his wrist, only to hear a crackling bone explosion, and his body was filled with inexhaustible frenzied energy. Wren took a deep breath, like a whale absorbing water, although most of the power of the lava crystals was absorbed by the maple leaf crystals, the spilled energy residues were turned into direct power to transform Wren's body, and the most intuitive manifestation of these powers was the ascension of the level. With Wren's inhalation, his breath grew slightly, starting from level five, level six, level seven, and level eight...... Up to level ten!

A level 10 Wind Sword Hero! His current strength has reached a level that was unimaginable before! Wren shook his fist, and he had a feeling that if the steel tower was still standing in front of him, he could seriously injure or even kill him with just one slash.

Dingding.

A system quest has been sent to improve: Congratulations on completing the hidden quest Lava Crystal, rewarding 5,000 gold coins and a mysterious skill.

Combat skills? Wren was in ecstasy, and when he opened his backpack, he found a book with a quaint yellow cover, which had a question mark on it, indicating that it was not identified. When Wren clicks on it, he gets a prompt:

"Do you want to check the combat skills?" (Once selected, the result cannot be changed.)

Wren's expectant choice was. The interface of the system flashed with a dazzling golden light, and a large amount of information flowed into the brain.

"Burst flames, month-level lower grades. A combat technique that uses the power of fire, through which the power of fire can be attached to any attack, and when used to the extreme, it can give birth to a fire hell in a radius of thousands of miles. ”

Then the running skills of the burst flame were presented in Wren's mind one by one, and after reading all of them, Wren couldn't wait to try them. You must know that Eve's Nine Waves are just a moon-level top grade! Wren took out the broken knife from his backpack, took a step forward, and at the moment when he slashed out, his hands suddenly lit up, and his whole body suddenly turned red from the hilt upwards, and a flame sword gang flew out and slashed at the corpse of a dead adult flame-tailed crocodile, and the sword gang touched the hard scale armor of the flame-tailed crocodile, just like Yangchun met white snow, cut it in half like cutting tofu, and blasted the brown rock out of a pothole the size of a basin before disappearing.

Wren swallowed with a gulp, before he needed at least three times more rage bonuses to break through the defense of an adult crocodile, but now a blow in a normal state can easily solve an adult flame-tailed crocodile, if it is five times the rage...... It is estimated that even if this group of flame-tailed crocodiles stood in a row, he could behead them all.

Although there is a level increase in this, don't forget, this is only the first time he has used the martial art of Burst Flame, and there are a lot of jerky points, and I am afraid that he will exert thirty percent of his power. In the future, as he became proficient in Burst Flame, it would be more than enough to increase this power by two or three times. What's even more rare is that this martial art can not only be used on a knife, but every part of his body, punches, kicks, knees, and even the top of his head, can be used unexpectedly, which must be a nightmare for opponents who don't know his details.

Wren was very happy in his heart, and felt that he had gained a lot from this trip to the underground, not only did he increase his level significantly, but he also obtained a month-level low-grade martial art, and the balance of gold coins in the mall was also five thousand. When the lava crystallization energy is exhausted, it turns into a fiery red seed, although the value of this seed is not as valuable as the full lava crystal, but it is also a valuable thing, and it is extremely popular as the main material of the super life potion, and the official price given is at least 10,000 gold coins.

When Wren was full of joy and calculated the harvest, his heart jumped, and he remembered that he was in a stalemate with the steel tower before he fell to the ground. But what about the steel tower people? Now Wren doesn't take the steel tower seriously, but during the time he was unconscious, the seriously injured glasses had no power to fight back.

But now he's standing here. Wren had a chill down his spine, and an ominous premonition made him want to gag, and he turned around slowly, and when he saw that the huge body of the steel tower was out of breath. In the middle of his straight-line distance from the steel tower, the glasses fell there.

There was a terrible heavy sword stuck in his back, the brown rock was stained red with blood, and his glasses were closed, motionless, lifeless.

"No !!" Wren screamed.
