After hearing this, Marquis Shenwu walked closer to the stone gate and looked it up and down.

The huge stone gate is two meters wide and three meters high, which is quite amazing in this underground space.

There are countless lines on the stone gate, and the lines that connect to each other look like regular curves.

There are so many lines, but there is no pattern at all.

After looking at it for a long time, I actually felt dizzy.

The same was true for Bai Yunfei's mental strength, and he felt a sense of discomfort in his brain.

It wasn't just him, it was the same for everyone who was observing.

Marquis Shenwu took a look and, with a thoughtful look on his face, took out the key he was carrying.

When he saw the key, Bai Yunfei was stunned for a moment.

I have the impression that I have also obtained a key like this.

It is one inch in size, has more than twenty teeth, and a ring at the back.

The key that Shenwu Hou took out was similar, but obviously different.

"Everyone! There must be a keyhole on this stone door. Please look for it."

The entire stone gate was so dizzy because of the lines that even Bai Yunfei felt dizzy, let alone those warriors.

After hearing what this person said, everyone simply gathered close to the stone door and began to look for the keyhole inch by inch.

I have the key, but I can't open the door because I can't find the keyhole. This is a bit unreasonable.

However, even if everyone searched inch by inch, they still couldn't find the keyhole.

The scholar was also anxious at this moment, because it was risky for everyone to enter this place.

The same was true for Marquis Shenwu. He held the key but showed a helpless look.

Bai Yunfei put his hand against the stone door and began to pour his internal energy into it.

This is just a last-ditch effort, so let's just give it a try.

With the injection of internal energy, the lines on the stone gate seemed to come alive, and a line lit up from the edge.

With the injection of internal force, the lines began to extend forward gradually at a very fast speed.

However, Bai Yunfei's expression turned a little ugly.

In order to light up these lines, the internal force required is too great. Looking at all the lines, Bai Yunfei was terrified. It is absolutely impossible for him to do it alone.

"Everyone! Lighting up the lines requires inner strength. I can't do it alone. Everyone has to do it."

The rest of the people did not move, with suspicion in their eyes.

Seeing this, Bai Yunfei simply let go, but the lines quickly became dim.

He coughed suddenly a few times, which aggravated his injury.

Although he had taken the pill, he was seriously injured before and was only 70% healed now.

When everyone saw this, they were thinking about it. The scholar said, "Everyone! Please work together and light up these lines and give it a try."

As he spoke, he stood in front of the stone gate, pressed one hand on it, and his internal energy began to surge.

Seeing him like this, the others had no choice but to contribute. More than twenty people simply touched the stone door with one hand, circulated their internal energy, and poured it into it.

Crazy internal energy poured into it, and almost instantly, all the lines began to light up and spread rapidly towards the entire stone gate.

In just twenty breaths, all the lines converged in the middle of the stone gate, forming a spot of light. With a loud bang, everyone hurriedly withdrew their internal strength, stepped back a few steps, and watched the changes in the stone gate.

The light did not disappear as the crowd retreated. After the sound, the light spot flashed with amazing light, and then it actually sank.

The light then gradually disappeared.

The scholar took a step forward and looked at the small hole with a look of surprise on his face. He turned back to look at the Marquis of Shenwu and said, "My Lord, please open the stone door!"

Shenwu Hou stepped forward, looked at the small hole, and tried to insert the key into it.

With a clicking sound, the stone door trembled, and then with the key as the dividing line, the stone door suddenly opened and moved apart.

The keys fell to the ground.

Marquis Shenwu picked it up and put it back in place.

After only ten breaths, the stone gate was completely opened.

The darkness inside became bright as it was opened.

But a cold wind blew out from it, and everyone felt a chill.

There is no wrong version in the 1619 book forum!

A long passage going forward.

A warrior who was close to the stone gate walked in first. However, as soon as he entered, his face turned ugly. He quickly retreated and shouted, "There is poisonous gas!"

Everyone hurriedly held their breath, but even so, the gas was still able to penetrate through the skin, just a little slower.

The scholar seemed to have expected this and took out a bead from his arms.

The moment he saw the bead, Bai Yunfei was stunned for a moment.

This thing is fiery in color all over, as if it carries a flame force.

The man threw the beads directly in.

With the appearance of this bead, it seemed as if a cyclone appeared in the air. With the naked eye, streams of air rushed towards the bead.

Bai Yunfei has already recognized it. This should be the Essence Fire Pearl he needs!

It was such a surprise! I didn't expect to encounter this last type of Seven Revolutions item under such circumstances.

Although it was quite dangerous, I was still lucky.

After a full incense stick of time had passed, the air flow stopped. The scholar walked over and picked up the Essence Fire Bead.

Marquis Shenwu, however, looked at the precious pearl with envy.

"Sir, you are really extraordinary! The Fire Pearl is a rare treasure, but I remember this thing, it seems that Bao Jinghou had one before."

After saying this, he looked at the man with a playful smile.

The scholar smiled and said, "My Lord, there is no need to test it. This thing belongs to the Marquis of Baojing. I just stole it."

Shenwu Hou gave him a thumbs up and praised him, "Sir, you are not simple! The strength of Baojing Hou is also half a step into the air, sir, you are really powerful!"

This person just smiled and said to everyone: "The poison gas here has been dealt with, everyone go in!"

Bai Yunfei frowned, because his mental power sensed that the previous gas was not poisonous gas, but corpse gas. I am afraid that many people died in this underground palace! The corpse gas was so strong.

With a cautious look on his face, he moved forward with the crowd, practicing his martial arts and healing his wounds.

This is a long corridor, but when everyone reached the end, they found that there were two stone doors, leading to two directions.

This stone door does show obvious signs of opening and closing.

Everyone gathered near the two stone doors.
