He realized that he might have discovered a more advanced spiritual stone.
Moreover, there are quite a few spirit stones in this pile, with more than 500. In terms of energy level, it is approximately equivalent to the energy contained in five million spirit stones.
The most valuable thing in this secret room is not other treasures, but this pile of neglected "waste rocks".
At this moment, no one noticed this corner. Lin Mu quietly put the pile of stones into the space ring.
Then he ignored the competition from others and turned his attention to the front of the secret room.
In front of the secret room, there is a high platform with a big drum placed on it.
This drum, three meters in diameter, is interconnected with the hull and cannot be moved.
The mysterious thing is that its drum skin is made of unknown leather, and it is full of an ancient and desolate atmosphere.
While Lin Mu was observing, the treasures around him were gradually being robbed.
After freeing up their hands, other people's eyes also focused on this big drum.
"Ghost Drum."
Everyone's eyes showed a fiery light.
This drum is the ultimate goal of people's trip.
Although the ghost drum cannot be moved away, it is enough as long as you can use it to increase your potential and even break through the realm.
For a warrior, one's own potential and cultivation are fundamental, and everything else is auxiliary.
"I come."
Soon, a seventh-level great martial artist walked up to the ghost drum.
Then, he took a deep breath, clenched his fists, and punched the drum forcefully.
boom!
What was unexpected was that before his fist hit the drum skin, a terrifying ripple burst out from the drum skin and ejected him.
In an instant, this seventh-level martial artist flew hundreds of meters and landed outside the secret room.
"Wow."
After landing, he vomited blood suddenly, his face was pale, and his eyes were full of fear.
"Not everyone can play the ghost drum."
Seeing the look of horror and confusion on many people's faces, Fang Yan explained to everyone, "Thirty years ago, the ghost ship appeared once, and a senior of my Tianyahai Pavilion entered it."
"He told me that if you want to play the ghost drum, you must have great potential. People with insufficient potential will not be able to play it."
After everyone heard this, they were relieved.
The expression of the person who was knocked away was even more depressed.
Doesn't this mean that his potential is not good?
"I'll try too."
Everyone present is an elite and has sufficient confidence in themselves. Although one person has failed, the others still have a strong desire to try.
Soon a second person jumped onto the high platform.
"drink!"
After jumping onto the high platform, he kept walking, clenched his fists, and rushed towards the ghost drum.
However, he still failed.
Just like the first person, his whole body was blown away before his fist even got close to the ghost drum.
Then, the third and fourth people also failed.
Until the fifth person, this is a ninth-level great martial artist from Longting Villa.
As he punched out, the ghost drum finally sounded.
"Boom"
The terrifying sound waves were like a flash flood, sweeping across all directions in an instant with overwhelming force.
boom!
The ninth-level great martial artist was swept away by the impact.
Almost at the same time, the other fourteen people in the secret room, including Guo Qi, were also rushed out of the secret room by the 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 ones with the lowest cultivation level are all ninth-level great martial artists.
Most of the others are peak martial arts masters, and others are half-step martial arts masters and strong martial arts masters.
Therefore, the other twenty people were not surprised to see each other. Only when they saw that Lin Mu was not blown away, everyone's eyes showed deep surprise.
Yan Qingxia's eyes also flashed with a faint brilliance.
This guy actually has some skills.
For some reason, she couldn't help but remember the scene where Lin Mu forcibly kissed her and fed medicinal materials into her mouth, and her ears turned red inexplicably.
"This ghost drum doesn't seem to be very accurate. What potential can a person with a yellow-level martial arts have?"
Chen Hao openly mocked.
The people in Tianyahai Pavilion and Longting Villa were all surprised when they heard this.
Everyone had seen the conflict between Chen Hao and Lin Mu before, and they knew who he was talking about as soon as they heard it.
But they didn't expect that Lin Mu's martial arts qualification was only yellow level.
For elites like them, the lowest level of martial arts is usually no lower than green level, most of them are green level and blue level. Lin Mu's is indeed very unusual.
"Does this kid have some kind of strange treasure?"
Everyone couldn't help but think so.
They never believed that a person with Huang-level martial arts had any potential. The only explanation was that he had a rare treasure.
But at this time, people didn't pay much attention to these, and looked more at the ghost drum.
"I'll do it this time."
A peak martial artist from Longting Villa jumped onto the high platform.
Boom
The people who can stay are indeed extraordinary.
The next moment, this peak martial artist beat the ghost drum.
And after the sound, he was not knocked away.
Boom!
After this ring, his confidence also greatly increased and he rang it twice in a row.
Buzz!
The space vibrates, and the farther back the ghost drum goes, the more terrifying the sound waves it generates become.
When the third ring echoed, the last two ninth-level great martial artists present could not resist and were directly knocked away.
Boom!
Continuing, the peak martial artist rang the fourth bell.
Even more terrifying sound waves reverberated, and this time he couldn't hold on any longer and was blown away.
At this time, there were eighteen people left in the secret room.
The ones who suffered the most were the two ninth-level great martial arts masters who were knocked away behind them.
They were able to persist until this point and were able to beat the drum at least once, but unfortunately they were blown away by the sound waves of three times and lost the chance.
"I come."
Based on previous lessons, people with lower strength or lack of confidence in their potential can go up in advance.
To avoid being blown away by the sound waves before the drum is struck.
Gradually, there were fewer and fewer people in the secret room.
Half an hour later, only ten people were left.
There are four people from the Iron Blood Alliance, Yu Jingfeng, Yan Qingxia, Chen Hao and Lin Mu, and three people from Longting Villa and Tianya Haige respectively.
At this time, everyone's eyes fell on Lin Mu, full of surprise.
The ten people present were all masters on the Hidden Dragon Ranking.
Talented people outside like Chen Hao can only be ranked at the bottom.
But this Lin Mu, who is not even a great martial artist, is still here.
"This person must have an incredible treasure."
Everyone thinks so.
"Lin Mu, look at it clearly for me. There are people outside the world, and there is talent. Don't be so self-righteous in the future."
Chen Hao took a deep breath and stepped onto the high platform.
Without hesitation, he gathered his true energy and punched the ghost drum with one punch.
After punching out, he didn't stop and punched five times in a row.
dong dong dong
The sound of the drum was like the roar of an ancient beast, raging in the secret room and setting off a terrifying storm.
After six rings, he glanced at Lin Mu.
Originally, he wanted to knock Lin Mu away with the sound of drums, but now that he saw Lin Mu was still there, he couldn't help but feel a little disappointed.
This also aroused his ferocity, and he beat the drum more and more fiercely.
