"Patriarch Mu, those barbarians are really terrifying, do they have any weaknesses!" Duan Li'er smiled bitterly.

"We don't know about this, and we've been looking for their weaknesses, but we haven't found them for thousands of years!" Mu Zhenwen shook his head and said.

"Then what are we going to do, we don't want the ball back!" Duan Li'er said bitterly.

"Let me think about it, you go and rest first!" Mu Zhenwen called someone to come and led Duan Li'er and Luo Changqing to a resting place, but he hurriedly returned to his residence and opened a small teleportation array! Teleported out of his room.

……

"Old patriarch, although these two young people are very weak, they have great potential, and they also want to retrieve the black ball, do you think you should help them!" Mu Zhenwen stood in front of an old man with a frowning face and said respectfully.

"You mean, let them go to that place?" Although the old patriarch was old, his voice was very hearty.

"Well, with their abilities, they should get a lot of harvest in that place! Plus, that black orb was robbed because of me, so I beg you to let them go to that place! Mu Baling said with a guilty face.

"Alright! Going to that place doesn't make a difference to us anyway! ”

"Thank you, old patriarch!" After Mu Baling finished speaking, the old patriarch waved his hand, and Mu Zhenwen appeared in his room again.

After a day of rest, Duan Li'er and Luo Changqing also adjusted their state to the best, but they were called out to the hall by Mu Zhenwen early in the morning.

"It's so much better!" Mu Zhenwen asked kindly.

"It's a lot better, it's just ...... Alas! Duan Li'er sighed.

"Little girl, don't worry, I've come up with a solution, but in the end, it's up to you!" Mu Zhenwen smiled.

"What a way!" Duan Li'er and Luo Changqing asked at the same time.

"There is a place in our Aoki Clan, and there is something in it that can stimulate the potential power in the human body, but how much you can improve, this depends on you!"

"Will this have side effects that will affect your future cultivation?" Duan Li'er asked.

"Nope! It's just that the place to find this thing is very special, and you can't be together! Mu Zhenwen said.

"Where?" Duan Li'er asked in a low voice.

"Under the Sky Tree!" Mu Zhenwen said with a smile.

"What?" Duan Li'er was surprised.

"Hehe, the bottom of the Heavenly Tree is so magical, even I can't figure it out! If you go, it's up to chance! Mu Zhenwen chuckled, and at the same time, his face showed a look of fascination.

He saw Duan Li'er and Luo Changqing's surprised expressions, and then said, "Are you willing to go!" ”

"Go!" Duan Li'er and Luo Changqing said in unison.

"Let's go!" After Mu Zhenwen finished speaking, a cyan crystal appeared in his hand, the crystal flashed, and the green glow vibrated greatly, so that Duan Li'er and Luo Changqing had to close their eyes.

When they opened their eyes, they found that they had come to another place, a place surrounded by red earthen walls, which could accommodate about forty or fifty people, and there were four walls, each with a green curtain on it.

"Pick one door and go in. It's all there to bring out the potential of the human body! You go in and look for yourself, it's big inside, and you may need a little patience! At this time, Mu Zhenwen's voice came.

"Patriarch Mu, what are they like?" Duan Li'er asked.

"I don't know, anyway, if you go in, the strength of those who come out will be improved!" Mu Zhenwen shook his head and said.

"You haven't been in?" Duan Li'er asked in surprise, such a place, if the patriarch hadn't been there, it would be too much to say.
