Lu Yu frowned slightly and took the box into his hand.
Looking at Chen Chengyuan's cautious movements, it seemed as if he was giving a piece of national jade seal to Lu Yu.
"Maybe it can improve your strength to level six or above."
Chen Chengyuan was silent for two seconds, and then looked at Lu Yu seriously.
Hearing what Chen Chengyuan said, Lu Yu became more serious.
Today, for Lu Yu, what can cheer him up the most is his improvement in strength.
Only when you are strong enough can you do what you want to do and protect the people you want to protect.
As for Lu Yu, as long as he is strong enough, he can guarantee his own safety.
What Ji Ningxue and the others need is Lu Yu's safe return to the Dragon Kingdom.
Therefore, if there is an opportunity to improve his strength, Lu Yu will definitely not miss it.
"Who gave this to you?"
Lu Yu paused for a moment, then raised his head and asked.
Chen Chengyuan glanced at Lu Yu, but did not answer.
When Lu Yu saw Chen Chengyuan's expression, he had already thought of something.
"Okay, then I won't ask."
"Is there anything else?"
Lu Yu put the box aside and looked at Chen Chengyuan and asked.
"there is none left."
Chen Chengyuan slowly shook his head.
"Then I'll go back."
"If anything happens, I'll come back to you."
Lu Yu didn't waste any time, immediately picked up the box, stood up and left Chen Chengyuan's room.
Chen Chengyuan sent Lu Yu to the door, stood by the door, and watched Lu Yu leave.
There was a complex expression deep in his eyes, making it impossible to figure out what he was thinking.
…
At night.
The bright moon hangs high tonight, and the night sky is filled with stars.
In this quiet night, the warrior restricted area seems to be getting quieter and quieter.
It was completely silent, and all members of the Rain League, except for some disciples on duty, had already rested.
In Lu Yu's room, the lights were on.
Beside the bed, Lu Yu slowly turned over the box in his hand by the light.
This box with a simple shape seems to be made of a special kind of wood, and it feels heavy and heavy.
And it feels soft and soft, and the palm feels like touching a round jade.
"It must be a few years old, but I didn't expect it to be so well preserved."
Lu Yu looked over it over and over, and then prepared to open it.
There are no locks or hooks on this box, so it seems easy to open.
However, Lu Yu pressed hard along the position of the box lid, but the box did not move at all.
"Um?"
Lu Yu was stunned and pressed his palms again, but there was still no sign of the box being opened.
"what's the situation?"
Lu Yu frowned, with confusion in his eyes.
He originally thought that the box might just contain some inherited martial arts or something.
Now it seems that this box is really not simple!
Could it be that there is some secret in this?
When Lu Yu thought of this, he was even more impatient to open it.
However, after looking around the corners of the box, I still don't have any clue.
Twenty minutes later, Lu Yu put the box on the table with a bang.
He had tried countless methods just now, including biting it with his teeth, but the box still didn't move at all.
It's like being welded to death.
Chen Chengyuan only gave him this thing, but did not tell him how to open the box.
This made Lu Yu very helpless.
"Why do you people like to engage in such mysterious things?"
Lu Yu gritted his teeth slightly and couldn't help but complain.
He had been thinking about what Mr. Lu had left for him for a long time.
In the end, it was Lu Zihan who held the key in his hand and gave it to Lu Yu to open it.
Fortunately this time, he didn't even have a clue.
If Chen Chengyuan didn't know, he might really be blind.
Lu Yu frowned and thought for a few seconds. He originally thought that he would ask Chen Chengyuan early tomorrow morning.
But he really couldn't control the urgency in his heart. At this moment, his heart felt like a cat's claws scratching at him, making him unable to settle down at all.
"Go and call Sect Master Chen over."
Lu Yu reached out and touched his chin, and immediately shouted to the door.
"Yes, Alliance Leader."
Someone answered immediately outside the door.
Soon, Chen Chengyuan arrived at Lu Yu's place.
"How to open it?"
Lu Yu was a little irritated and pushed the box in front of Chen Chengyuan.
"this……"
Chen Chengyuan was stunned when he heard this, then took the box in his hand and looked over it again and again.
