After a whole day, Lao Chen's door finally opened slowly.

Old Chen with red and swollen eyes came out of the room listlessly.

Seeing old Chen's appearance, Xu Shaotang's heart suddenly sank. He quickly went up and asked, "how's it going?"

"I don't know!"

Old Chen's pale face was full of helpless look, slowly said: "this is the most complex lock I've ever seen, I still haven't figured out the principle of this lock! I don't know if I can open it. Even if I can, I guess I can't open it without more than a month's time! "

"More than a month..."

Hearing what Lao Chen said, Xu Shaotang couldn't help smacking his tongue slightly. It took Lao Chen three days to open the gravity lock he Shibi installed last time. Now this box is almost a month.

Although he didn't know what the lock in the box was, Xu Shaotang already knew how hard it was to open it.

No wonder they didn't encounter any mechanism traps when they were looking for this box. The biggest mechanism trap was on this box!

"Even if it is a month, it may not be able to open it!" Old Chen said with a bitter smile: "I still need time to understand the principle of this lock."

"We can't stay here for a month!" Xu Shaotang looked at Lao Chen bitterly and tried to discuss with him: "otherwise, I'll find you a safe and quiet place. There are special people waiting for you 24 hours a day. How about you calm down and study the lock slowly?"

He certainly can't keep waiting for old Chen to unlock the lock all the time. In that case, he may be bored to death before the lock is opened.

But he can't just leave the box with Lao Chen. It's not that he's worried about Lao Chen, but that he's worried about some people who have ulterior motives, such as Joseph and Milo. Although they get along well now, if they have the chance to take the box away, it's estimated that they will take a chance in all probability.

"Yes!"

Laochen nodded and said, "anyway, I'm a loner. It's the same where I study this lock!"

He knew the importance of the box in his heart, and he knew that Xu Shaotang could not put such an important thing in his hand. He could not refuse the things that Qin Guozhu had been staring at himself.

Thinking of Qin Guozhu, old Chen found that he didn't see Qin Guozhu. He asked Xu Shaotang in doubt, "what about them, old Qin?"

Xu Shaotang said with a smile: "when they leave, they say they don't give pressure and let you do your best. Even if they can't open it, they won't blame you."

"Xu Shao, did you send them away?" Old Chen exhaled a long breath of turbid air, and suddenly felt a sense of relief in his heart. "Please find a place for me to study the box slowly. By the way, there should be many experts in our country. I suggest that we should find some people to study the box together. More people will always have more strength."

"No problem. I'll tell Mr. Qin about it later." Xu Shaotang nodded his head and asked curiously, "have you studied the whole day and seen any clues?"

"I see some." Old Chen said slowly: "the lock in that box is also a built-in lock, just like the gravity lock before us, but the lock in that box is much more advanced than the gravity lock. Now I have no idea about its operation principle."

When he said this, Xu Shaotang had a general understanding in his heart. Xu Shaotang reached out and patted him on the shoulder and said, "well, you haven't eaten for a day. First, you can find something to cushion. When you wait for the place, someone will prepare something for you! Although unlocking is very important, your body is also important. We all expect you to open the lock! "

"Good!"

Lao Chen nodded, and with Lao Jiu's help, he walked back to the room with exhausted steps.

Looking at the tired figure of old Chen, Xu Shaotang walked slowly to Milo and Joseph and said, "you also heard that the lock in the box can be opened at least for more than a month. You can choose to follow and wait slowly, or you can go back to China first. When there is news here, I'll let you know."

When they heard Xu Shaotang's words, they were immediately embarrassed, and their eyes were full of thinking.

After thinking about it carefully for a while, Joseph slowly looked up at Xu Shaotang and asked, "Mr. Xu, what old Chen said should not be what you asked him to say when you helped him carry the box in yesterday?"

"You suspect that I don't want you to see the contents of the box, so I deliberately let Lao Chen say so?" Xu Shaotang asked Joseph faintly.

Joseph nodded slightly. He couldn't deny it. He said with a smile, "Mr. Xu, you are too cunning. Although I don't want to think that his words were inspired by you, it's really possible, isn't it?"

"There's a possibility of farting!" Xu Shaotang curled his lips, looked at Milo and Joseph lightly, and said with a smile, "even if I don't want you to see the things in the box, what can you do?"“……” Two people slightly one stagnate, at the same time shake head way: "have no!"

They really have no choice. Let alone that the box has arrived in Xia state, even if the box is not in Xia state, they can't snatch the box from Xu Shaotang by gathering the power of the psionic group and the round table riding regiment.

"Then it's over!" Xu Shaotang snorted: "if I don't want to show you, I don't want to go around such a big circle with you!"

"All right!" Joseph looked at Xu Shaotang helplessly and said, "it's impossible for us to wait here for at least a month. Mr. Xu, I hope you can keep your promise. Once the box is opened, please inform us at the first time. Joseph thanks in advance."

"Milo, thank you first!"

Looking at the two people in front of him, Xu Shaotang said helplessly: "I mean what I say! Joseph, I hope you keep your word

Joseph knew that Xu Shaotang was saying that he would no longer support that person. He nodded and said, "I'll keep my word, too! I don't have much to say about a man who doesn't care about our own lives! "

"It's not too late for you to understand!" Xu Shaotang gave Joseph a smile and said, "in addition, if there is any discovery about prehistoric civilization in the future, I hope you can inform me at the first time! As Mr. Milo said, we don't know whether we will be enemies in the future, but at least at this time, we have a common enemy! "

"All right!" Joseph nodded heavily.
