Yi Hao's Yuan Huo has been invincible since it was refined, and he didn't expect that it would lose its effect on the demon beasts in front of him and the environment here.

"Fireball!"

"Flame Cord!"

"Vulcan Spear!"

Yi Hao didn't give up, and one after another flame spells were released in the flick of his fingers, and they quickly attacked the four demon beasts. But when these Yuan Huo spells hit the demon beasts, they only made their bodies shake slightly, and they didn't cause any substantial damage.

"Split the mountain!" Yi Hao raised his heavy sword without a blade, and rushed towards a demon beast like a whirlwind and slashed at its back.

"Roar!" The demon beast seemed to sense the great threat brought by Yi Hao's sword, and its body turned sideways in place, its long mouth raised to meet Yi Hao's giant sword with its sharp fangs. Seeing this, the other demon beasts also spit out giant trees to besiege Xiang Yihao.

There was a loud bang. A huge anti-shock force came from Yi Hao's arm, and he took a few steps back again and again while wielding the giant tree that was attacked by the other demon beasts without a blade. The smoke and dust cleared, and the fangs in the long mouth of the demon beast in front of it were unscathed, but its body took a few steps back, and a trace of blood spilled from its mouth.

These monsters are immune to spells, and even splitting mountains can only slightly injure them, and it seems that they can only break them with force. Yi Hao looked at this group of demon beasts solemnly.

"Roar" The demon beast that was repelled by Yi Hao roared angrily, and it rushed towards Yi Hao with all its might. Seeing this, the other three demon beasts also rushed towards Yi Hao. The four demon beasts surrounded Yi Hao in the middle, and the four beasts fought into a ball, and the smoke and dust rolled in the place of the battle.

As time passed, Yihao gradually felt struggling. But on the other hand, these demon beasts are as alive and vigorous as ever, without the slightest sense of exhaustion.

Yi Hao saw such a stalemate situation, and his eyes showed helplessness.

While fending off the attacks of the four demon beasts, he slowly retreated towards the edge of the woods. The four demon beasts seemed to be very angry with him, especially the injured demon beast who chased after Yi Hao.

After Yi Hao retreated to the edge of the forest while fighting, those demon beasts looked at the edge of the woods with horror in their eyes, and they didn't dare to take half a step out of the woods. They wandered near the edge of the woods, looking at Yihao and roaring.

Yi Hao looked at the four demon beasts in the woods and couldn't help but smile bitterly. Unexpectedly, he was forced by these beasts, and he had to escape from the woods to avoid their pursuit.

Then, he sat cross-legged on the ground, pinching the trick and frantically absorbing the vitality in the air to recover his cultivation. After a while, Yi Hao slowly opened his eyes. He looked at his outstretched hands, his eyes full of satisfaction.

Unexpectedly, not only is the Yuan Force abundant, but also the Yuan Force is very pure. The speed at which he absorbed vitality here was far greater than that of the secret realm. Feeling the abundant Yuan Force in the dantian, Yi Hao looked at the demon beast in the woods that had been injured by him and had not retreated, his blood was boiling, and his fighting spirit was high.

Yi Hao got up, stretched out his right hand, and the heavy sword suddenly appeared in his hand without a blade.

When the demon beast saw Yi Hao standing up, he immediately stared at him fiercely. Yi Hao stepped over the edge of the forest with his sword and pounced on the demon beast.

"Split the mountain!" Yi Hao fell to the ground like a meteor, and slashed towards the demon beast. The demon beast raised its mouth and spat out a piece of giant wood to meet the sword light.

The giant tree met with the sword light, but it did not stop its progress in the slightest, and slashed towards the long mouth of the demon beast like a bamboo. The demon beast was slashed backwards and retreated a few feet away, and a stream of blood spurted out from the corner of its mouth.

Yi Hao didn't dare to hesitate when he saw this, for fear that he would attract the other three demon beasts. Immediately, he slashed the mountain, and continued to slash towards the demon beast with great speed.

The demon beast was furious, and its eyes flashed fiercely towards Yi Hao's bladeless heavy sword. There was a wail, but its mouth was injured and hurriedly resisted, and the mouth of the demon beast was cut off and fell to the ground.

Yi Hao was overjoyed when he saw this, and immediately used his whole body of yuan power to chop the mountain and slash down.

"Puff" two chopping mountains slashed at the body of the demon beast one after another, and its huge body was split in half, and blood was scattered all over the ground.

The corpses and blood stains of the demon beasts that fell to the ground suddenly smoked, and then there was a loud "zizi" sound, and a trace of green vitality floated up. When these vitality floated out, the corpses and blood stains of the demon beasts on the ground all disappeared.

After these vitality floated out, they seemed to be a little dazed. But after sensing Yi Hao, he quickly pounced on him and drilled into his mouth and nose. Yi Hao was shocked and waved his hand to fan back these vitality. But these energies seemed to be non-existent, and all of them penetrated into his body through his palms.

As soon as these energies entered Yi Hao's body, as if he had drunk the elixir and jade dew, he suddenly felt that his body became lighter, and a strong sense of intoxication hit. His body and soul seemed to float up, ascending to the upper realm.

Yi Hao's hands and feet, as well as his whole body, lost consciousness, and his fingers could not move at all. Yi Hao's eyes were round, and his eyes were frightened! He frantically forced himself to use the Divine Forging Technique, and a cool feeling came from his brain, and Yi Hao suddenly woke up.

"The vitality of this demon beast is really terrifying after inhaling it into the body!" Yihao's back was soaked with cold sweat. He knew that if he was drunk just now, he might really fall asleep and never wake up again.

"What is this?" Yi Hao felt that the green vitality flowing into his body seemed to be different from ordinary vitality, and it was very sticky.

The pure orange sapling in its body trembled with excitement when they saw this green vitality. A huge suction force spontaneously arose from the pure orange sapling, and it couldn't wait to absorb this green yuan force.

After absorbing the green energy, the trunk of the tree grew more than a circle, and a third bud slowly emerged.

Yi Hao felt the change in the orange sapling in his body, and couldn't help but be overjoyed. He used Aoki Immortal Gong again, and found that the exercise worked more smoothly, and his ability to perceive the vitality of the wood system was doubled.

"Could it be that this green vitality can improve people's Yuan Root grade!" Yi Hao seemed to have a guess, and his eyes were ecstatic. He first consulted the books related to Yuangen in the library of Sanyang Sect, and then consulted Senior Brother Wu Youjin of Lieyang Peak to know that Yuangen has innate and acquired theories.

The innate root is inherently untransformable, and it is present in a person's body as soon as he is born. For example, his super-grade fire root belongs to the innate elemental root.

The Acquired Origin Root is due to the imbalance of the Five Elements due to the lack of Fire Vitality in the Five Elements in this Heaven and Earth, resulting in some cultivators having Origin Root defects. In order to make up for these shortcomings of human cultivators, some mysterious characters make up for some or some Yuan Roots through some heaven and earth wonders. The orange sapling at Yihao's dantian belonged to the acquired root of the day after tomorrow.

Now, the green vitality he inhaled in his body was actually able to enhance people's innate and even acquired roots, which was unheard of.

"It's definitely a chance, I didn't expect to be met by myself." Yi Hao looked in the direction of the three demon beasts in the woods, his fists clenched, and his eyes were full of heat.
