When they came outside, they saw that Feng Jiu was already waiting for them there, so they stepped forward with the stone: "Feng Jiu, do you see the stone we brought back?" ”

Each of them carried a large stone in his arms, about fifty pounds.

Feng Jiu glanced at them and nodded, "Well, let's start!" Hold the stone behind you, squat and jump around this area for half a month, and then run around here for half a month. ”

As soon as her voice fell, she looked at Tunyun on the side: "Keep an eye on them, if you don't do it, or if you're lazy, just bite them, don't kill them, you can treat the injury." ”

"Huh." Swallowing Cloud answered, crouching on the grass and staring at them.

And after several people heard his words, except for Luo Fei, who didn't know that Swallowing Cloud was originally a divine beast, the other people all had numb scalps......

In the following month, Feng Jiu handed over several of them to Swallow Cloud to keep an eye on, and after laying an enchantment outside the cave mansion, he began to refine the elixir inside.

From this day on, several people could hear the rumbling sound coming from the cave, and sometimes, there was thunder in the sky, at first Luo Fei didn't know the identity of Feng Jiu's ghost doctor, until later, after asking a few people for Duan Ye, he knew that he was actually a ghost doctor.

Although he was an informant on the side of the academy and someone reported the news to him, he only knew that Feng Jiu was from the Six Star Academy, but he didn't know that he still had such an amazing identity.

No wonder, no wonder Duan Ye and the three of them would follow him so easily. Following the ghost doctor for a year is a good thing that no one else can ask for.

They squatted and jumped with the stones for half a month, and at the beginning, they had no strength after holding on for less than two hours, and it was difficult to breathe, but that Tunyun was really faceless, just listening to Feng Jiu's words, he really showed sharp teeth to them, and the few people who wanted to rest could only continue to grit their teeth and hold on.

Until, half a month later, the physical strength gradually improved, even if they squatted and jumped around the fifty pounds of stones on their backs for a morning, they would not take a break, but because the time of half a month was up, they began to run, still running with the stones, and this run passed another half a month.

In it, they seemed to be cut off from the outside, perhaps under the effect of Feng Jiu's enchantment and formation, the people outside, the fierce beasts outside, had never entered here, so that the peace inside made them forget that they were in the Hell Mountain Range at this time......

As soon as the one-month period arrived, Feng Jiu, who had not come out of the cave for a month, walked out on this day, she was still dressed in the dazzling red, clean as ever, no damage, and no mess, which made people wonder if he was really alchemy in the cave during this time?

That look, just like resting in the cave for a whole month, not haggard and tired at all, still the same radiant appearance, clear eyes contain fierceness.

Although they were curious, they didn't dare to ask him, God knows, they were shocked by the momentum of the mentor he brought out, and they instinctively had a trace of fear in their hearts, how dare they ask him about it?

Seeing Feng Jiu come out, Tunyun happily came to her side and squatted, looking well-behaved and not seeing the cruelty when chasing and biting a few people, and seeing a few people's teeth glaring fiercely.

Feng Jiu glanced at a few people, his gaze swept over them, and then he spoke......
