Duolai was a little surprised that the Black Dragon Ancestor didn't cause him any trouble. After all, he was no longer of any use to him.

Duolai slowly recovered his original appearance and stood on the ground in human form. He said in a deep voice, "Actually, if you can't handle it, I will deal with Nightmare Ancestor myself. I am confident that I can deal with him in one go, but I need your cooperation, which seems to be out of the question now."

The Black Dragon Patriarch looked at Duolai and his heart suddenly trembled.

What does Dolai mean by this, can he handle a level eight by himself?

Blowing the dragon.

The old black dragon was a little wary. He looked at Duolai, groaned for a moment, and then said, "I will accept your favor this time. As long as I am here, the other level sevens in the Beiyuan Mountains will not take the initiative to invade your Albis Mountains. However, the daily low-level confrontations will continue. This is my bottom line."

Dolai looked at the old black dragon and smiled faintly, "No problem. I have no intention of expanding my territory. The Albis Mountains are the territory of me and my descendants. Besides, when we try to break up the will of the Nightmare Ancestor, it's best to keep some tricks up our sleeves. It would be best if we can get some information from him."

The old black dragon nodded and said, "Of course. I will share the information with you. Nightmare is the number one enemy of all living beings in our West Ring Continent."

Dolai nodded. He saw the battle in the sky was getting farther and farther away. He guessed that it was the old black dragon who was controlling it. After all, controlling the actions of Nightmare gave him a certain degree of self-control. So he said, "Then we'll see you later."

As he spoke, his figure slowly faded and disappeared from the spot.

He left the Black Dragon Ancestor's dream.

At Black Dragon Mountain, Duolai opened his eyes, slowly stood up, glanced at the old black dragon behind him, then looked at some herbs around him, and muttered, "Forget it, I'd better collect some reward."

The magic power transformed into dozens of big hands, which put the surrounding herbs and some ambergris into the storage ring, and then he walked out of the cave in a leisurely manner.

When leaving the cave, Dolai saw the dragon bat still guarding the entrance faithfully, and nodded to him.

When Longfu saw Duolai, he was a little confused. Why did this guy come out again? Does he think this is his home?

He released his aura, covering the doorway, and immediately said viciously, "Dole, what do you mean?"

Dolai looked at the dragon bat with an expressionless face.

"What do you mean?"

"Do you think this is your home? You can come and go as you please?" Dragon Bat roared. There was a strange fluctuation in his roar, as if he wanted to intimidate Duolai.

Circles of silver waves flickered around Duolai, offsetting the vibration of the sound wave. He continued expressionlessly, "Old Black Dragon will wake up in three days at most. Congratulations. You were right not to leave."

Longfu was stunned, and his momentum slowly dropped, "You are not lying to me?"

Dole waved his hand impatiently, took the Turin Bone Tower off his waist, and threw it in his hand like a ball, "Get out of my sight right now."

The aura on the Turin Bone Tower has reached level eight. A thick aura of death is released, which is extremely corrosive. Dragon Bat only took a look at it, his face changed drastically, and he quickly retreated.

"Human, you want to start a war?" he roared.

Dolai said calmly, "You are no longer worthy of being my opponent."

He threw the wizard tower out, a white light flashed, and the whole person disappeared on the spot. Then the wizard tower enlarged, carrying an extremely strong breath of death, and rushed towards the sky at an extremely fast speed.

Behind him, a thick wave of air rolled and formed a white line tens of kilometers long, and bursts of loud rumbling sounds spread across half of the mountain range.

Seeing this, Longfu was suddenly shocked.

The air waves rolled and blew directly on his face, and his whole body took two steps back.

Is this Dorae's new wizard tower? This is too brutal, it directly broke the sound barrier?

Longfu was silent, a cold thought arose in his heart, and he stood there motionless.

These geniuses of the human race are too abnormal. This guy only took twenty years to surpass the more than a hundred years of practice he had spent. It’s really sad to think about it.

The human race is so abominable.

He didn't know how long he stood there waiting, when suddenly a voice came from inside.

"Dragon Bat, I have sensed it and found that you are the only one left?"

Dragon Bat finally came to his senses and knelt on the ground in a hurry, "Ancestor Black Dragon, yes, all those above level seven have run away."

The old black dragon's voice was filled with fatigue. "Tell them all to come back. I'm fine now. I'm not afraid of the nightmare again. The Beiyuan Mountains are safe now."

Dragon Bat shuddered and asked in a low voice, "Grandmaster, are you okay?"

The black dragon was immediately furious. "Duolai is gone, what do you think happened to me? Also, let me announce that from now on, high-level monsters and Duolai will not interfere with each other, and low-level monsters will consume each other as agreed before, and go down the mountain as usual in winter."

Longfu was shocked, "Ancestor, are you really going to let Nadulai go?"

The Black Dragon Patriarch snorted coldly, "Go ahead if you think you can beat him. I'm afraid he will tear off your wings right away and eat them as snacks."

Longfu was silent. Yes, he could no longer defeat Duolai.

He was silent for a moment, then said, "Since the ancestor has returned, I will go and send a message."

The old black dragon's voice continued, "After you're done, hurry up and practice. Get to level eight. If you're not at level eight, you'll just be cannon fodder."

Longfu was stunned and nodded quickly.

The battle with the Nightmare Ancestor explained everything. If one was not at level eight, there was no chance of resistance. If the Nightmare Ancestor had not invaded as Lord Black Dragon, the dragon bat would have run away and caused trouble for Dolai, and then been killed or suppressed by Dolai.

That guy is very ferocious now, and the upgraded wizard tower is so terrifying.

But is it easy to reach level eight?

The sign of level eight is to fully comprehend a rule. It sounds easy, but it is extremely difficult to do. It is so difficult that Dragon Bat is stuck at level eight so far. There is only the last level left, but he cannot comprehend it.

When the Black Dragon Ancestor saw that the dragon bat was silent, he said, "I'm going to rest. You can contact me by yourself, and then there will be no more sound."

…

Dolai's clone returned to the Albis Mountains and placed the wizard tower in the middle of the mountain range. Standing at the highest point, I looked at the entire Albis Mountains.

The storm field is now becoming more and more solid, and the energy contained is becoming more and more huge. He can take back this power into his body at any time if he wants. In this way, he, who is at level seven, is truly invincible at level seven. No matter whether he is at the high level of level seven or the top level of level seven, he is invincible at level seven.

The energy of an entire storm field is much greater than the energy of level eight.

After solving the problem of the old black dragon, Duolai breathed a sigh of relief and looked towards a mineral vein in the mountain.

At this time, Baal was still sleeping, and no one knew how long he would sleep, but the blood aura in his body was becoming stronger and stronger.

Ashe also regularly poured blood potion into this guy's mouth, but no matter how much he poured, this guy couldn't wake up.

Bal is determined to be promoted to level eight in this world, but he doesn't know how much difference there will be between being promoted to level eight and being promoted in their world.
