"Mu Cheng, why are you here?" Zi Ling looked at Mu Cheng behind him and asked in puzzlement.

"Aren't I worried about you? Besides, your injuries are not fully healed yet, so don't try to show off. Leave this place to me. "

"You? You're even more unreliable than that child. Let that old man do it."

"Thunderclap Sword, Lightning Thrust." Mu Cheng sneered in his heart. With such carelessness, Black Mountain Old Devil will definitely suffer a loss.

Mu Cheng released all of the Fa Li in his body and instantly transferred it to the Thunderclap Sword. He had never done this so easily before.

That huge electric light emitted a blinding light in the forest. A terrifying destructive force exploded from the Thunderclap Sword.

"Hmm?" At this time, Black Mountain Old Devil's expression changed for the first time. Facing such powerful lightning, even with his tyrannical body, he would not be able to survive.

"Good boy, you've really broadened my horizons. Such a powerful move, you actually managed to pull it out without saying a word."

Before the Black Mountain Old Devil could say anything, he was drowned out by the sound of the huge electric light.

"Hehe, this Mu Cheng sure is secretive. With this level of strength, even if Black Mountain Old Devil and I were to switch seats, we wouldn't feel good."

Gu Qianche could not help but twitch at the corner of his mouth, his heart jumping in fright, under this kind of heavenly might, even a Na Spirit Master would have to avoid him.

"Mu Cheng, you're actually this strong?" A flash of disbelief appeared in Song Weiyi's eyes, but was quickly replaced by an intense unwillingness.

"It must be the Mysterious Heaven Jade. This damnable Mysterious Heaven Jade, if I knew that Mu Cheng would be so hard to deal with today, it should have been annihilated by me back then. I truly regret my actions back then."

Regret flashed across Song Weiyi's eyes.

"Mu Cheng, half a year ago, your strength had not yet broken through the broken soul, but half a year later, it had already reached the point where I can only see your back figure. I wonder what your achievements will be like half a year later, is it possible that I can't even see your back anymore?"

Zi Ling looked at Mu Cheng's back, his heart suddenly moved, and his face turned gloomy. Facing such a terrifying electric light, Black Mountain Old Devil was surprised, but being shocked meant that he would not die under this electric light.

However, he was sure that he would be injured, and that was to see how Black Mountain Old Devil would receive this blow. Mu Cheng borrowed the electric light to see Black Mountain Old Devil's movements clearly.

"You want to hide? Do you think you can?" The corner of Mu Cheng's mouth rose into a sneer.

With a cold snort, Mu Cheng's hands suddenly changed direction and he chased after Black Mountain Old Devil.

"Haha, Black Mountain Old Devil, if you were to directly receive this attack of mine, I'm afraid that you would at most be severely injured."

"But now, I'm not so sure. Do you think your speed can be faster than my lightning? What a joke."

Mu Cheng's ice-cold voice resounded in the air and entered everyone's ears.

"Hmph, my Black Mountain Old Devil has been through this mountain range for dozens of years, yet we have never been in a sorry state like today."

"Boy, you're the first. I'll remember you, but I'm afraid this little bit of lightning might not be able to take my life."

A look of seriousness flashed across Black Mountain Old Devil's face. This time, he was completely defeated by Zongtian Sect.

"That might not be the case. Since you want to play, then I'll play with you until the end. How about it?"

Mu Cheng smiled, his face filled with confidence.

The injured Black Mountain Old Devil was not their match at all, but if they wanted to leave Black Mountain Old Devil, that would be a problem.

BOOM! A burnt smell spread through the forest.

Mu Cheng's face was also a bit pale. After using his full strength, he also felt the strain and also a bit of exhaustion.

"Ah Niu, keep an eye on Song Weiyi for me." Mu Cheng immediately used the Voice Transmission Technique to send a message to the Beaver. At this moment, Mu Cheng was at his weakest, and could not be careless at all. Mu Cheng was very cautious of Song Weiyi, no matter what happened, Mu Cheng would always be on guard against him.

At this time, Mu Cheng also let out a sigh of relief. He looked at the desolate mountain forest, and through the thick fog, Mu Cheng saw a charred corpse inside.

"He died just like that?" Mu Cheng found it hard to believe that the Black Mountain Old Devil was hacked to death by him just like that.

"Kid, there will be a day when I will get my revenge."

Not far away, a figure suddenly appeared. It was Black Mountain Old Devil.

"The only thing is, the Black Mountain Old Devil is still alive. If we don't cut the weeds and remove the roots, there will be endless trouble in the future."

Gu Qianche said loudly, then chased after him in a certain direction.

"Zi Ling, what Master Gu said is right, you should go too. Black Mountain Old Devil is already heavily injured and is not far from there. Mu Cheng glanced at Zi Ling.

"But your current situation isn't very good. If we leave and the old demon returns, I'm afraid you will be in danger."

Zi Ling said worriedly, but all of this was in Song Weiyi's eyes. It seemed that the woman he liked cared about another man.

"Just you wait, Mu Cheng. There will be a day when you die in my hands. And there's also Zi Ling, she's mine."

Song Weiyi swore in his heart as a stern look flashed past his eyes.

"Hehe, Zi Ling, you can go. If Black Mountain Old Devil comes over, I'll make sure he gets into trouble."

Mu Cheng calmly said, but his tone was filled with killing intent.

"Alright, I'll be going then. Be careful." Zi Ling glanced at Mu Cheng, and then disappeared from the spot.

"This is probably the first time I've used up all the Fa Li in my body."

Mu Cheng laughed at himself before slowly sitting down and closing his eyes to rest.

"I knew you would come back. Since you have come, then don't go."

After a while, Mu Cheng opened his eyes and said calmly.

"Hmph, brat, who do you think my Black Mountain Old Devil is? If I don't leave something on you, I won't be willing to die. "

The Black Mountain Old Devil said coldly, as a black shadow suddenly appeared in front of Mu Cheng.

"Beaver, charm him." Mu Cheng growled as the Thunderclap Sword in his hands suddenly flew out from Mu Cheng's body.

"Ah …" On the black figure's body, a red halo suddenly appeared and surrounded Black Mountain Old Devil.

"Dammit, this kid is actually proficient in illusion techniques. It seems like I can only withdraw today."

"Master, the beaver's strength is not enough. That Black Mountain Old Devil used his life's demon essence and let him rush out."

In Mu Cheng's mind, the self-reproach of the beaver flashed.

"En, it's fine. Awesome, I believe that the Black Mountain Old Devil will lose his strength greatly. He will not be able to fight for a long period of time in the future."

Moreover, this Black Mountain Old Devil was a peak Earth rank demon beast, even if it was a neo-spiritual realm Ranker, it might not be his match. Now that he had injured the Black Mountain Old Devil, as long as he was informed about this matter, they would be very willing to send people to tell him about the suppression.

"Since you have come, you should leave something behind."

Mu Cheng's ice-cold voice resounded in the air and a chilling aura filled the air.

"Ah …" A mournful cry reverberated within the forest.

"Kid, the hatred for my lost arm is irreconcilable. Sooner or later, I will attack Zongtian Sect. Kid, I will remember you."

Black Mountain Old Devil let out a furious roar as he disappeared into the forest.

"Hmph, at least you ran fast." Mu Cheng picked up one of the arms on the ground. There was still blood on the remaining arm. In an instant, the severed arm turned into a withered tree trunk.

"So it's a Tree Demon that has reached the Awakening Realm." Mu Cheng sneered in his heart.

In a dark corner, a voice filled with hatred was heard as it stared at Mu Cheng.

"Mu Cheng, you'll die by my hands sooner or later." The man slowly got up and walked in another direction.

In the forest, Black Mountain Old Devil's face was pale and weak. He stopped under a tree to rest, his sinister expression slowly retreating.

"Who?" Black Mountain Old Devil bellowed, he stood up and looked at the forest.

A figure walked out from the forest. It was Song Weiyi.

"Black Mountain Old Devil, you also have that day? Weren't you very arrogant just now?" Song Weiyi's eyes flashed with ridicule.

"Hmph, so it's a kid like you. Could it be that you think that because my Black Mountain Old Devil was injured, my Black Mountain Old Devil was bullied by dogs?"

At the same time, his tentacles had already sunk deep into the ground, ready to absorb the surrounding wood essence at any time. This was also the reason why Dao Sect was unable to take out a peak Earth rank demon beast.

In this mountain range, Black Mountain Old Devil could recover his strength at any time. Even if he was seriously injured, as long as he did not die, Black Mountain Old Devil could recover in a short period of time.

As long as they were not abnormal cultivators, Black Mountain Old Devil would dare to fight against middle stage Na Ling cultivators. As for people below the neo-spiritual realm level, Black Mountain Old Devil did not even put them in his eyes.
