The reason why Mu Youluo would say such a thing was because she felt that this old man must be a master, and at the moment when the old man dropped her down just now, Mu Youluo did not feel the fluctuation of spiritual power on his body, you must know that this is a world where spiritual power is the law of cultivation, but this old man did not use spiritual power, which shows that he is not ordinary.

Although Mu Youluo's attitude was sincere and his words were full of respect, the old man didn't buy it, but looked at her with a smile.

"It's not impossible for me to let you go, as long as you help me complete something, then I will naturally let you go."

Mu Youluo frowned and continued, "Senior, please speak." ”

"As long as you help me clean this library, I'll let you go." After finishing speaking, the old man continued to return to the soft couch to drink wine, and with a slight wave of his hand, he put down the brocade dust hanging on the beam.

Although Jinchen was put down, he still couldn't speak, he walked in front of the old man, asked an old man to help him unlock the spiritual method, took it and glanced at him, turned around and continued to drink, in this regard, Jinchen had to shake his head helplessly.

There are five floors in the library cabinet, and there are countless books in it, because of the random stacking, there are not so many books on the shelves, resulting in a lot of books piled up on the ground, if you want to clean the library cabinet, you must arrange the books on the ground.

The two of them went under the bookshelf and picked up the books, but no one cleaned them for a long time, and a lot of dust fell on the books, and they had to wipe them clean like dust on the books.

"If you want to wipe it, wipe it carefully, if there is a little dust or a little wrinkle on the book, you don't want to go out, and besides, except for the books stacked on the floor, all the books in the shelves will be taken out for me to wipe clean." While the two were cleaning, the old man suddenly said a word, which made Mu Youluo and Jinchen both sigh and frown at the same time.

This is only the first floor, but there are tens of thousands of books here, and it would take hours to clean this floor, not to mention the upper four floors.

Jinchen thought about it and decided to directly use spiritual power to remove the dust, but just as he raised his hand and wanted to use spiritual power, there was a huge pain in his body, and he couldn't help but stop.

Mu Youluo also saw Jinchen's discomfort, his face became a little pale, and fine sweat broke out on his forehead.

Speaking of which, Jinchen has no substance, although he seems to have an excellent good body, he can also feel pain, but this pain comes from the soul, not the body, but he can feel it, this pain is physical.

"I advise you to put away that little bit of caution and clean up for me, otherwise you will be the one who suffers."

Mu Youluo was stunned and nodded towards Jinchen.

Jinchen didn't use spiritual power, the pain in his body slowly faded, and the whole person breathed a sigh of relief.

"You take the books down first, I'll wipe the shelves first, and then wipe the dust off the trees." Mu Youluo looked at Jinchen and said.

Since they can't get out, and the old man doesn't allow them to use spiritual power, they can only do it themselves, they still have very important things, and they must speed up.

A bookshelf is at least four or five meters high, and if Jinchen wants to move all the books down, he must fly to the side of the bookshelf and take down all the books, but this time, there are not many books he can take down, and it takes a lot longer.
