Suddenly, a whirlwind rose out of thin air, and all the classics flew open and swirled like they had wings, forming a tornado.

Ban Ming, Yang Yaren and Yun Changdi were in this tornado formed by thousands of books.

Emperor Yun Chang opened his mouth wide and saw a book staying in front of Ban Ming's eyes. Then the pages quickly flipped from beginning to end at an incredible speed, then suddenly closed, flew out of the tornado, and landed on the ground.

At the same time, another book has been staying in front of Ban Ming.

Before I could react, Ban Ming had finished reading this classic and flew out.

In this way, in less than ten minutes, all the classics were read by Ban Ming, and the tornado of Books disappeared silently in the process.

Emperor Yun Chang looked around with some difficulty, and saw that all the books were stacked neatly, forming a wall of books.

"Is there any clue?" Yang Yaren asked in the language of the earth.

Ban Ming nodded slightly and said, "I found something useful, let's go."

Although Emperor Yun Chang could not understand what Ban Ming and the others were saying, he could guess one or two of them from their expressions. His face changed a few times, and suddenly made an amazing move. He knelt on both knees and bowed deeply to Ban Ming.

Ban Ming frowned and looked at him, saying, "What do you mean?"

"I beg you to give me mercy!" Emperor Yun Chang's voice trembled slightly. He didn't dare to say in detail what Ban Ming wanted to take out. In his opinion, anything Ban Ming and the others took out must be amazing.

Ban Ming thought about it and felt that after all, he had obtained some possible key clues from the South Vietnamese royal family, so it was nothing to give some rewards. He immediately said: "Get paper and pen."

Emperor Yun Chang was ecstatic and almost rolled and crawled to get paper and pen.

Ban Ming was a little surprised. The pen of this civilization was very different from that of ancient Earth. It looked like a fountain pen, but it had no ink. The tip of the pen was inlaid with an extremely small unknown black stone. It could present a very clear black handwriting when it was stroked on the paper.

Ban Ming quickly wrote more than a dozen pages and handed the stack of manuscripts to Emperor Yun Chang.

Immediately, without waiting for Emperor Yun Chang to say anything, he and Yang Yaren moved and disappeared into the library.

After only a dozen breaths, the two of them had already left the city and landed on the top of a small hill outside the city.

"You are so generous that you actually passed the Chi Guang Technique." Yang Yaren teased.

"Just treat it as a good relationship." Ban Ming said with a faint smile: "This planet is not too far from the third space jumping point. If one day this civilization develops, it may reach the solar system through the third space jumping point. If you find that you can rush to light, it should be a very interesting thing."

Yang Yaren ruthlessly attacked: "I don't know how many years will happen. Is there any radius of light? Then I'll tell you... Let's see, what clues have you found?"
