Diwu Yue sighed helplessly, hugged the box and gestured to his sons, then left Yao Ling's villa in the blink of an eye.

Not long after they left, the originally sleeping Yao Ling slowly opened his eyes. Whether or not Mu Family can survive through this calamity will depend on you. "

Everything seemed normal on the way back. Diwu Yue and his sons squeezed onto the bed and considered whether to open the box. In the end, they felt that it would be better to not open it for the time being, thus, Diwu Yue could only hide the thing.

The morning of the second day, mother and son duo did not get up yet. Mu Zhengnan waited for a while before he asked his servants to come over and wake them up.

"Oh, it's so early for Grand Grandpa!" Diwu Kong was ranked second, Diwu Lang was ranked third, and Diwu Yue was ranked last.

"It's still early? It's nine o'clock. " Looking at the four of them who were still half asleep, Mu Zhengnan felt both angry and amused. Usually they would wake up early, why was it so late today?

"You don't want to wake up after sleeping with the Mummy." Diwu Kong said as a matter of course. Of course, only they themselves knew the specific problem.

"Oh right, don't wander around if you don't have anything to do in the next few days. Just stay in this house."

Diwu Yue glanced at Mu Zhengnan. Could it be it was because of what happened last night? Looks like I have to ask him later. "No matter what she thought in her heart, she still obediently answered Mu Zhengnan's question. "Got it, Grandfather."

Mu Zhengnan nodded and continued his breakfast.

Mu Baiming doubtfully glanced at Diwu Yue, but Diwu Yue's performance was just like usual, so he didn't see anything.

After breakfast, they returned to their room and Diwu Chen switched on his computer. After a period of hard work, most of the places had been monitored, even Mu Zhengnan's study room.

If he couldn't get rid of the people inside the mansion, then it would seriously hinder what happened next.

She checked all the suspicious people on one side, in order to sit on the bed and research Yao Ling's collection of black boxes. As expected, the curiosity of humans was very strong. Diwu Yue and his sons had been guessing what was inside all this while.

In the end, Diwu Yue came up with an excuse, "Maybe looking at the things inside will be helpful to our movements."

Creak! Creak!

The box was slowly opened. Inside was a book that seemed to have existed for a very long time. The words on it were written in small letters. If one did not have a certain level of skill, even if one obtained this book, they would not know whether the contents were true or not.

"What's written on it?" Diwu Yue turned his head towards his youngest son. This guy spent his days reading books and studying history. He said that he would be helpful to the hospital's research, and this time, he could finally be of use.

"Medicine Manual."

"What?" Diwu Yue shouted in shock.

"Mmm, I won't mistake the words on it. It's the《 Pharmacopoeia》." Diwu Kong said with absolute certainty.

"Then let's see what's written on it."

Diwu Kong received the order, and carefully observed for a moment, before putting on a special pair of white gloves and taking out the book.

He also explained, "It has been a long time since anyone has touched this book. I don't know the exact time, but I can tell that it has been here for hundreds of years. Even if someone had gotten the box, they might not have been able to read it. Even if he could read this book, he might not be able to understand it. "
