The nearby ground was affected by the thunder, and the entire ground sank almost several meters.
But the main hall remained motionless, like a mountain.
On the walls of the main hall, the precious light flickered, then disappeared, and returned to its dusty and simple appearance.
Everyone's expressions changed. The two powerful realm masters could not break through such a barrier.
"Let's all try."
"With such a barrier, there must be valuable treasures hidden inside."
The magic weapon stimulated everyone's nerves, and everyone around them tried various methods, but they were still unable to break the barrier.
"Qiang!"
A touch of sword energy fell from high in the sky, and the long sword crossed the sky and landed hard in the direction of the main hall.
However, there is an invisible barrier above the void of the main hall, blocking all attacks. Even if the sword energy from the outside world is soaring and murderous intent is rampant, it still cannot destroy the main hall.
Wei Mengting put away her sword and shook her head: "This barrier requires a specific method to open, and brute force will not work."
"Governor Lu, you might as well try it and see if you can open this barrier."
"Yes, if even you can't do anything, then there's really nothing we can do about this barrier."
The others said one after another.
Everyone wants to take a look at the things in this hall. Among all the people present, Lu Yu has the most powerful combat power.
"Okay, I'll give it a try."
Lu Yu raised his hand and dropped it. The strong palm force mixed with the abundant mana instantly formed a huge golden palm in the void and fell heavily!
There was another violent sound, deafening and reverberating in all directions. Many people heard the sound, only to feel a sting in their eardrums and their hearts beating violently. They were also affected by the aftermath.
This time, everyone finally saw clearly the barrier hidden outside the hall.
The cyan barrier is like a light shield, firmly protecting the entire hall inside, blocking all attacks from the outside world. There are ancient bells and tripods on the barrier, and the ones on the surface of the alchemy furnace in the eunuch's prison.
The words are the same and they are obviously products of the same era.
"Alas, even Governor Lu can't help it. I'm afraid this place is really unreachable." Everyone shook their heads and sighed.
Lu Changqing asked: "If we attack it with the arrows from the immortal weapon just now, I wonder if we can break the formation?"
The power of the immortal weapon is supreme. Once it is used, its power will destroy the world.
This sharp arrow is not an incomplete fairy weapon like the Compass of Life and Death, but a complete fairy weapon.
The arrow's light is immortal and cold, and anyone will feel an unprecedented pressure from it.
"Opening it should require other means."
Lu Yu didn't say it clearly.
He seemed to have seen such a barrier somewhere.
After thinking for a while, Lu Yu suddenly woke up. He remembered that Meng Tian had brought him to the army's treasure house before, and that there was such a barrier surrounding the treasure house.
At that time, Meng Tian showed his waist card and entered naturally without any obstruction.
The previous memories appeared before Lu Yu's eyes one by one.
"Lu Yu, let's go. There is no need to waste time here. I suspect there is a treasure deep in this place, and we must not let King Qi get there first." Holy Lord Huang Tian said.
Lu Yu shook his head and said, "I'll try again."
He stepped forward and already took out the waist badge that Meng Tian had given him before.
