Yu You saw the Black Devil Tiger running towards Yu Hao, and hurriedly chased after him, and stabbed the Black Devil Tiger in a hurry. The Black Devil Tiger only felt that his buttocks were cold, the chrysanthemums were tight, and his rapid figure was obvious.

The Black Devil Tiger received this fatal blow, and suddenly the wolf's body trembled like an electric shock, and let out a tragic howl that shook the heavens, and the surrounding demon hunters were shocked when they heard it.

Yu Hao took the opportunity to adjust his breath, simply recovered his vitality, and cooperated with Yu Youyi to carry out a rough abuse of the Black Devil Tiger one after the other, Yu Congbei seized the opportunity to give an order, and all the demon hunting teams surrounded and joined the ranks of abuse, and there were bursts of roars in the forest.

The Black Devil Tiger can be said to be extremely aggrieved, his body is already bloody, and the Black Devil Tiger roars extremely unwillingly, wanting to escape.

"Still want to escape?" Yu Hao took a leap and grabbed the Black Devil Tiger Tiger Tail with his right hand.

"Buzz!" the Black Devil Tiger wagged its tail violently and flicked it over. Yu Hao's palm flipped, easily dodging the blow, and the palm slapped directly on the Black Devil Tiger's buttocks, and the violent energy made the Black Devil Tiger stumble. At this moment, Yu Hao used his Xuanjin finger with all his might, and his finger prints were vertical and horizontal, hitting the Black Devil Tiger alive, and thick blood oozed from the corners of the Black Devil Tiger's mouth, and he fell powerlessly after a low roar. The Black Devil Tiger struggled to stand up, but soon fell down, struggled several times, and finally couldn't move anymore, before dying, he turned the tiger's head and glared at Yu You with "resentment", before finally closing his eyes unwillingly.

Yu Hao was afraid that this guy would die again, so he took Yu You's blood scale knife and threw it hard, and the blood scale knife flew away like lightning, easily breaking through the fur of the Black Devil Tiger and inserting it into the Black Devil Tiger.

After waiting for a while, seeing that the Black Devil Tiger was really out of breath, Yu Hao pulled out the bloodscale knife inserted in the Black Devil Tiger's body, straightened up, and exhaled.

"Haha...... Hao'er, well done!" Yu Congbei and the guards had already come over, all staring at the lying Black Devil Tiger, with excited smiles on their faces.

"Hao'er, I didn't expect you and You'er to kill the Black Devil Tiger, what a hero!" Yu walked over laughing from Bei, but his face was pale, and he was obviously not lightly injured.

"Fourth uncle, how are you?" Looking at Yu Congbei, who had a broken arm, Yu Hao felt uncomfortable in his heart.

"Fortunately, Hao'er, I still have to thank you, fortunately you saved me in time, otherwise I wouldn't even have time to explain the aftermath!haha!" Yu Congbei patted Yu Hao's shoulder with his other arm and laughed heartily.

"Fourth uncle, don't say that, your injury ....." Yu Hao said seriously.

Yu Cong's face became more and more pale: "It's okay, I'll go back first, you can deal with it here." ”

"Okay!" Yu Hao said, asking the escort team to escort Yu back to Yu Mansion from the north.

Yu Hao used Yu You's blood scale knife to cut open the head of the Black Devil Tiger and take out the magic crystal nucleus, but he didn't expect that the black demon tiger's magic crystal nucleus was actually black, which made Yu Hao frown for a while.

The magic crystal nucleus is divided into colors according to the elements of demonic beast cultivation, similar to the power of the five spirits of human beings, the five spirits of wind, thunder, water, fire and earth correspond to blue, purple, blue, red and yellow, but he never knew what element black represented.

"Third brother, show me, I haven't seen the magic crystal nucleus of a seventh-order demonic beast, I heard that it's worth 200,000 gold coins?" Yu You came up and said.

"Take it!" Yu Hao threw the Black Devil Tiger's magic crystal core to Yu You.

Yu You took the magic crystal nucleus and looked back and forth curiously, and suddenly the black magic crystal nucleus seemed to have been absorbed by something, and it slowly became smaller in Yu You's hands at a speed visible to the naked eye, and it only took a moment to turn into a pile of slag.

"Damn, third, what's going on?" Yu You exclaimed.

Yu Hao was also like seeing a ghost, his face was full of disbelief, this was the first time he had seen the process of refining the magic crystal nucleus with his own eyes, but Yu You also refined it too quickly, this is a seventh-order demon crystal nucleus, even if it is refined, it will take a year or two to absorb the yuan power inside.

Suddenly, Yu You's body trembled violently, a scorching burning sensation suddenly rose on his body, his emotions gradually blurred, and he suddenly became extremely excited after a few breaths.

Seeing the condition of Yu You's body, Yu Hao suddenly asked nervously, "Second child, what's wrong with you?"

Yu You said in horror: "I don't know, I feel hot and cold, what is this on me?!"

At this time, a layer of red light appeared on Yu You's body like a silkworm cocoon, quietly enveloping his body, which looked very vivid in the sunlight, it was a color that was difficult to describe, this blood red gave people a feeling more vivid than the red of Yu You's body meridians, but it was full of lively vitality.

The blood-red light gradually became richer, and the aura similar to the Black Demon Tiger continued to emanate from Yu You's body, and his body began to tremble slightly, and then, from the blood-red, a wisp of black light quietly appeared, and it was slightly emitted above his body.

The warm light of the sun could not enter the black light on Yu You's body, and on Yu You's forehead, a blood-red king character slowly appeared, and on his skin, there was also a layer of curly blood-red magic patterns, and there was a layer of identical black magic patterns under the blood-red magic patterns, and the superposition of the two layers of magic patterns seemed to have a strong three-dimensional effect. These magic patterns were not only densely covered on Yu You's body, but also spread to his face.

"Black Devil Tiger?"

Yu Hao observed nervously, at this time, Yu You was like a humanoid Black Devil Tiger, and this change was also evil.

Half an hour passed, and all the colors on Yu You's body gradually faded and merged back into Yu You's body, and the strange double lines on his body disappeared, Yu You's originally healthy bronzed skin looked a little fairer, and even his face seemed to become a little colder.

When everything returned to calm, Yu You couldn't help but shudder, and said nervously to Yu Hao: "Third child, I won't become a black devil tiger, right?"

"Could it be that he inherited the Black Devil Tiger's blood and qi madness?" Yu Hao frowned, he had just seen Yu You's changes similar to when the Black Devil Tiger's blood and qi were mad.

"Third child, I actually broke through to the ninth star!" Yu You was a little incredible.

"You just turned into that ghost, I thought you went crazy!" Yu Hao glanced at him.

"Hurry home, this place is really infiltrating!" Yu You was a little afraid.

When he went to the corpse of the Black Devil Tiger and picked up the Bloodscale Knife, he was even more shocked.

The Black Devil Tiger's originally huge body had now become dry, and the essence and blood on its body had long since disappeared.

"Is it the Blood Scale Knife that absorbed the essence blood of the Black Devil Tiger?" Yu You and Yu Hao glanced at each other, and suddenly felt their scalps tingle.

After returning to the Yu Mansion, the two found the eldest uncle Yu Congdong and the fourth uncle Yu Congbei, and told them that the magic crystal nucleus had disappeared inexplicably, which made everyone in the Yu family very puzzled, but Yu Hao and Yu You did not tell them about the Blood Scale Knife.

Later, Yu You changed the topic and told Yu Congdong about Yu Hao's encounter with Master Hua of the Alchemist Branch, which made Yu Congdong extremely shocked.

Yu Hao also changed the topic, saying that he wanted to try alchemy, and wanted to ask Yu Congdong to go to the family business to get a few alchemy herbs and let him try it, Yu Congdong naturally agreed.

Although Yu Congdong was surprised that Yu Hao was favored by Master Hua, he didn't think that Yu Hao could refine the pill after studying alchemy for a few days, after all, Yu Hao had tried it before, but in the end, it didn't work.

So Yu Congdong also relied on Yu Hao and asked him to try it, after all, a few pieces of Hui Yuan Dan's medicinal materials were not expensive, so Yu Congdong sent people to simply take ten pairs of medicinal materials needed for Hui Yuan Dan from several medicinal material firms of the Yu family, and sent them to Yu Hao's courtyard that afternoon.
