Rumble!
Inside the sea of willpower, three hammers were battling it out. The heaven and earth seemed to have turned upside down while the seas and rivers seemed to have overturned from the intensity of this battle.
The sea in this context was the sea of willpower. The sky was the sky above the sea, with the apertures acting as the stars in the sky. Some of these stars were congregating together. This was the very first time Su Yu was able to witness an advancement into the Mountainsea Realm so closely.
Aperture fusion!
At the Mountainsea Realm, one needed to fuse at least seventy-two apertures. The moment one fused the first eight apertures, one would become a Mountainsea. What about the characters?
Since one could become a Mountainsea through fusing apertures, what was the role of characters in this matter? Why would one fail to fuse the apertures without first advancing one's characters?
That was the question Su Yu asked himself as he observed the process. But he was too busy to pay too much attention to that thought.
He had to focus on controlling the giant hammer before the first eight apertures became one. Otherwise, the advancement might fail and the sea of willpower itself might end up destroyed.
Suppress! And suppress!
The two hammers continued trying to suppress the giant hammer, attacking each other with vibrations. Su Yu's hammer was the weakest, forcing him to constantly try to dissolve the vibrations dealt toward him.
He was battling something with the power of a Mountainsea. Even with his willpower and character technique, he was still not as strong as a proper Mountainsea. Zhao Li had to multitask and focus on his advancement while handling the giant hammer. He was starting to feel exhausted. There were a few times where the giant hammer nearly broke through the encirclement and destroy the sea of willpower.
If it was a regular ninth-stage Cloudbreach in this position, the sea of willpower would have been destroyed long ago. Zhao Li was near his limits.
Seeing that Su Yu was still trying his best to fight the giant hammer, Zhao Li said, "You should leave. I'll suppress this hammer and allow you to retreat safely. You have learned all you need to know from me. This hammer is already an earth weapon even if we stop the forging here. It still has a small chance of becoming a heaven weapon in the future."
"After suppressing this hammer, I'll seal it. You can probably start using it at the Cloudbreach or the Mountainsea Realm. It has a high compatibility with you since you have taken part in the forging and know the Soul Expanding Art."
Zhao Li's voice reverbrated inside the sea of willpower.
He was near his limits. The giant hammer kept attacking his sea of willpower, interupting the fusion of his apertures. In fact, cracks were starting to appear on his sea of willpower. Since he was going to fail, he might as well leave his last words behind seal the hammer...
"I'm not interested in some garbage earth weapon."
"..."
The little furball's body started flickering in excitement at the mention of food. He moved about like a shadow and bit a chunk off the hammer every now and then, greatly reducing the pressure on Su Yu and Zhao Li.
Even Zhao Li was surprised to hear that. Was that little fellow so impressive? That little thing was actually able to fight inside his sea of willpower! Every bite of that little thing was able to cause the large hammer to shudder in pain.
In truth, Old Zhao would also suffer an intense pain from each bite, but he had been keeping silent about that. The hammer was basically his main character. It was merely being rebellious right now. He had to subdue it before he could use it. Thus, this was essentially a fight against himself. He merely found no need to make that clear.
Why? Because it was too embarassing. He had never heard of someone getting beaten to death by their own main character before. If this happened to him, it would turn him into the biggest joke in the history books. Perhaps Liu Wenyan and the others had experienced something similar, but they had an excuse since their characters were outsiders, not their own characters.
Meanwhile, his main character had been formed by himself. Thus, he couldn't accept this happening. The battle felt much easier after the little furball joined. They only needed to last long enough and the large hammer would run out of energy. But they had to make sure that it wasn't able to destroy Old Zhao's sea of willpower before then.
Unfortunately, his sea of willpower was already on the verge of breaking apart. Suddenly, Su Yu's eyes flickered as he recalled what he read from Liu Wenyan's notes. He looked up at the shining apertures in the sky.
Abruptly, he yelled, "Teacher, follow my lead! If you end up dying, I'll give you a grand funeral! But if you survive this, you will definitely grow even stronger than your initial expectation!"
"Shit! What are you doing?"
"Lure it to the sky!"
Right after saying that, Su Yu's hammer soared into the sky. Old Zhao's hammer did the same. The two hammers worked together to force the large hammer up into the sky with them.
There were around eighty stars in the sky. Initially, Zhao Li only had seventy-two apertures. He had subsequently opened more, but Su Yu couldn't help shaking his head at this pitiful speed. Apart from the area occupied by the stars, the rest of the sky was blanketed in darkness.
Su Yu started making his calculations. He then aimed at an empty space and madly hammered it.
Old Zhao cursed, "That's my sea of willpower!"
"Open more apertures!"
Zhao Li finally understood. He asked in despair, "Forcefully?"
"Yes. Give it a try. Maybe it'll work. This was how my Teacher Liu Wenyan opened some of his apertures in the past. He survived even as a mere Mental Tempering Stage cultivator. He's doing pretty good. Teacher, we can take advantage of this large hammer's power to smash the apertures open. This might help you open more apertures and increase your strength. You won't get the chance to do this any other time."
Zhao Li gave it a thought and decided to throw caution to the wind. What was there to hesitate? Would he die if even Liu Wenyan survived? Su Yu might be right. With more apertures, he would grow stronger, his sea of willpower would become more stable, and his willpower would be more abundant.
The three hammers resumed their battle in the sky. Su Yu constantly lured the large hammer to strike the empty space in the sky, attempting to help Zhao Li open more apertures this way.
