Looking at Mu Yun, the four of them suddenly felt that they were witnessing the rising of a genius.

"In half a year, the fourth-grade human immortal, the forty-five-week heavenly immortal energy has flowed, reaching the fifty-year heaven, Brother Mu, you are so awesome!"

"Wrong!"

Hearing Fan Wuyan's words, Mu Yun smiled and said, "It's not the fifty-nine heavens, but... the fifty-nine heavens!"

As soon as these words came out, the four people present were completely stunned.

"Fifty-nine Zhoutian!"

Mu Yun's words immediately made the four of them completely stunned.

"My God, Brother Mu, don't scare me, my heart can't bear it!" Luo Cheng covered his chest, leaned against Luo Yun, and gasped, "No, I need artificial respiration!"

"I can't do it anymore, fifty-nine Zhoutian! Did I hear it wrong?"

Lin Zhixiu walked forward, looked at Mu Yun, and patted his cheek again.

Crazy!

"I originally planned to go into seclusion directly to the sixth-grade immortal realm, but after the fifty-nine cycles of the immortal energy, the last week was unable to operate in any case!" Mu Yun smiled bitterly and said, "It seems that it is not ordinary difficulty to upgrade to the sixth-grade immortal!"

"Of course!"

Lin Zhixiu looked at Mu Yun's unsatisfied look and smiled bitterly: "Brother Yun, you are really unsatisfied!"

"Fifth-grade human immortals, with the fifty-year cycle of heavenly immortal energy, the immortal body has been strengthened to a level comparable to a medium-grade immortal weapon."

"The sixth-grade human immortal needs a perfect operation of a large circumference. A large circumference is sixty small circumference. Now you are equivalent to re-entering all the previous immortal energy, and gathering it again. Of course, it is difficult. Otherwise, the sect would not set up, and only the sixth-grade human immortal realm warriors can become core disciples."

"Um!"

Hearing this, Mu Yun nodded.

He also understood in his heart that the sixty small circumference is a great circumference, the fifth to sixth grades are the operation of a great circumference, while the sixth to seventh grades are three great circumferences, the eighth grade is five great circumferences, and the ninth grade is nine great circumferences.
