Pounding!

Lin Mu's heart was pounding.

He realized that it was possible for him to discover a higher grade spirit stone.

Moreover, there are quite a few spirit stones in this pile, there are more than five hundred, and according to the degree of energy, it is about equivalent to the energy contained in five million spirit stones.

In this secret room, the most valuable thing is not other treasures, but precisely this pile of "waste stones" that has been ignored.

At this moment, no one noticed this corner, Lin Mu quietly, and quietly put this pile of stones into the space ring.

Then he ignored the others' arguments and turned his gaze to the front of the chamber.

In front of the chamber, there is a high platform on which a large drum is placed.

This drum, three meters in diameter, is interconnected with the hull and cannot be moved.

Mysteriously, its drum skin is made of unknown skin, and it is full of an ancient and desolate atmosphere.

When Lin Mu was observing, the surrounding treasures were gradually emptied.

After freeing up their hands, the eyes of others were also focused on this big drum.

"Ghost Drum."

Everyone's eyes are glowing with a scorching light.

This drum is the ultimate goal of people's trip.

Although the Ghost Drum can't be moved, as long as it can be used to increase its potential and even break through the realm, it is enough.

For a martial artist, his own potential and cultivation are fundamental, and everything else is an auxiliary.

"I'll come."

Soon, there was a seventh-order great martial artist who walked up to the ghost drum.

Then, he took a deep breath, clenched his fists, slammed into the big drum, and slammed it hard.

Bang!

Unexpectedly, before his fist hit the drum skin, a terrifying ripple burst out from the drum skin and bounced him out.

In an instant, this seventh-order great martial artist flew out hundreds of meters and landed outside the secret room.

"Wow."

When he landed, he vomited blood, his face turned pale, and his eyes were full of fear.

"The ghost drum is not something that anyone can beat."

Seeing that many people's faces were shocked and puzzled, Fang Yan explained to everyone, "Thirty years ago, the ghost ship appeared once, and a senior of my Tianya Pavilion entered it. ”

"He told me that if you want to beat the ghost drum, you have to have a lot of potential, and people who don't have enough potential can't beat it at all."

When everyone heard this, they were relieved.

And the person who was shocked was even more gloomy and lost.

Doesn't that mean that his potential is not good?

"I'll try it too."

And everyone present is an elite, with full confidence in themselves, although one person has failed, the others still have a strong attempt.

Soon a second person jumped onto the high platform.

"Drink!"

After jumping on the high platform, he didn't stop, directly clenched his fists, and rushed towards the ghost drum.

Still, he failed.

Like the first person, his fist was shaken away before he could get close to the ghost drum.

Then, the third and fourth people also failed.

Until the fifth person, this is a ninth-order great martial artist in Longting Mountain Villa.

With a punch, he finally beat the ghost drum.

"Knock ......"

The terrifying sound waves, like a flash torrent, instantly swept away in all directions with the momentum of overwhelming mountains and seas.

Bang!

That ninth-order great martial artist bore the brunt of being swept away.

Almost at the same time, the other fourteen people in the secret room, including Guo Qi, were also rushed out of the secret room directly by this sound wave, and fell heavily outside.

In an instant, there were only twenty-one people left in the secret room.

Among the twenty-one people, except for Lin Mu, the lowest cultivation level was all ninth-order great martial artists.

Most of the others are peak martial artists, and in addition, they are half-step martial arts and martial arts powerhouses.

Therefore, the other twenty people were not surprised to see each other, but when they saw that Lin Mu was not shocked and flew out, everyone's eyes showed a deep look of surprise.

Yan Qingxia's eyes also flashed with a faint brilliance.

This guy still has some skills.

For some reason, she couldn't help it, and remembered the scene where Lin Muqiang kissed her and fed the medicinal herbs into her mouth, and her ears turned red again inexplicably.

"This ghost drum doesn't seem to be very accurate, what potential can a person with a yellow-level martial vein have."

Chen Hao openly mocked.

The people of Tianya Pavilion and Longting Villa were all surprised when they heard this.

Everyone saw the contradiction between Chen Hao and Lin Mu before, and they knew who he was talking about as soon as they heard it.

It's just that they didn't expect that Lin Mu's martial arts qualification was only yellow-level.

For elites like them, the martial arts are usually not lower than the green level, most of them are green and blue, and Lin Mu is indeed very different.

"Could it be that this kid has some strange treasures?"

Everyone couldn't help but think so.

They never believed that a person with a yellow-level martial vein would have any potential, and the only explanation was that there was a treasure.

But at this time, people don't pay much attention to these, and more are looking at the ghost drum.

"I'll do it this time."

A pinnacle martial artist of Longting Villa jumped onto a high platform.

Boom......

The people who can stay are really extraordinary.

The next moment, this peak martial artist sounded the ghost drum.

And after a ring, he was not shaken away.

Knock knock!

After this ring, his confidence also increased greatly, and he rang twice in a row.

Airplanes!

The space vibrates, and the further back the ghost drum goes, the more terrifying the sound waves it produces.

When the third sound reverberate, the last two ninth-order great martial artists present couldn't resist and were directly shocked away.

Boom!

Continue, the peak martial artist, sounded the fourth ring.

Even more terrifying sound waves reverberate, and this time he couldn't hold on any longer and was blown out.

At this time, there were eighteen people left in the secret room.

The biggest loss was the two ninth-order great martial artists who were shocked in the back.

They were able to hold out until this point, and they were able to beat the drum at least once, but unfortunately they were shaken off by the sound waves that rang three times and lost their chance.

"I'll come."

With the previous lessons, those who are less powerful or who are not confident in their potential will go up in advance.

lest they be blown away by sound waves before the drum is beaten.

Gradually, there were fewer and fewer people in the secret room.

Half an hour later, only ten people remained.

There are four people in the Iron Blood Alliance, Yu Jingfeng, Yan Qingxia, Chen Hao and Lin Mu, and three people each in Longting Villa and Tianya Hai Pavilion.

At this time, everyone's eyes fell on Lin Mu, full of surprise.

The ten people present are all masters on the hidden dragon list.

Outside Tianjiao like Chen Hao can only be at the bottom.

But this Lin Mu, who is not even a great martial artist, is still there.

"There must be an incredible treasure in this person."

Everybody thinks so.

"Lin Mu, give me a good look, what is someone outside the world, genius has a day, don't be self-righteous in the future."

Chen Hao took a deep breath and stepped onto the high platform.

Without hesitation, he condensed his true qi and slammed his fist on the ghost drum.

After the punch, he didn't stop, and it was five times in a row.

Knock knock knock......

The sound of drums, like the roar of ancient beasts, wreaked havoc in the chambers, setting off a storm of terror.

After six rings, he glanced at Lin Mu.

Originally, he wanted to directly use the drum to shake Lin Mu away, but now seeing that Lin Mu was still there, he couldn't help but be a little disappointed.

This also aroused his ferocity even more, and the drums became more and more violent.
