Lu Yu frowned: "Could it be that the seal that imprisoned the devil has been loosened?"
Emperor Longchuan smiled bitterly and said: "I don't know this very well. I usually rely on keys to investigate."
"Unfortunately, there is no response to this key now. I can't figure out what happened inside."
Lu Yu glanced at it and immediately saw clearly the structure of the key.
It turned out to be an array eye.
This eye is connected to the entire sealing formation. Once there is any disturbance in the sealing formation, this key will react immediately.
Emperor Longchuan said: "The forbidden area is still somewhat dangerous now. Does King Chu still insist on going there?"
Lu Yu thought for a moment and said, "I still want to go."
There is no other place with spiritual energy in Longchuan Country.
And Lu Yu now urgently needs a place with dense spiritual energy to quickly improve his strength.
Emperor Longchuan sighed: "Well, that's fine, but if you practice there, if something happens, come out quickly."
A carriage was dispatched from the palace, and the emperor took Lu Yu to a barrier outside the city.
This was a bottomless pit. Lu Yu noticed that it was surrounded by countless camps and countless soldiers were stationed here.
Lu Yu frowned.
Although he hadn't even gotten close, he could already feel the bursts of demonic energy coming from the deep pit.
This demonic energy is extremely pure, and even has a hint of law.
"These soldiers are stationed here all year round. Once the sealed demon appears, their role is to hold it back for a while," the emperor explained.
"His Majesty!"
Several generals flew out from the camp and said respectfully to the carriage.
"Generals, this is the new king of Chu in this dynasty. Seeing him is like seeing me." The emperor began to introduce Lu Yu.
"King of Chu?"
The generals looked at Lu Yu with incredible expressions in their eyes.
Among the direct descendants of the royal family, I have never heard of such a young person.
However, since it was the emperor who had spoken, they could only camp.
"In the past few days, King Chu will enter the forbidden area, and you will wait outside. If there is anything that needs your help, you should do your best to help." The emperor said solemnly.
"I obey the order," the generals said respectfully.
After the emperor left, Lu Yu was immediately welcomed in by the generals.
"His Royal Highness the King of Chu, I would like to advise you not to go in easily." A general said in a deep voice.
Lu Yu said: "You mean it's dangerous, the emperor has already told me, I will naturally pay attention to it."
"That's not the case. There is a barrier outside the deep pit. We can no longer enter it." The general said bitterly.
Lu Yu felt a hint of the formation key in these people.
"Didn't you find anything unusual when you entered the deep pit?" Lu Yu asked.
The general shook his head repeatedly.
"We sent people in twice, the first time was 1,000 people, and the second time was 3,000 people. After entering, we didn't even send out a signal for help, and no one came out again."
"We wanted to continue sending people in, but a barrier suddenly appeared outside. We waited for an attack for a long time, but we still couldn't break through." The general said bitterly.
Lu Yu's eyes narrowed: "Take me to have a look."
He led Lu Yu to the deep pit.
This is a huge deep pit, with a radius of five miles. It is difficult to see clearly what is inside from the outside.
Next to the pit, there are many trebuchets, throwing stones into the pit.
But when these stones fell over the pit, they exploded one by one and turned into fly ash.
