Tang Shiyi and Zhou Shu were too close. In addition, he hadn't expected Zhou Shu to be able to break free from his restraints, so he naturally wasn't on guard.
Facing Zhou Shu's lightning strike, even with Tang Shiyi's cultivation, he was caught off guard and hit.
After succeeding in one move, Zhou Shu didn't hesitate at all. The spiritual essence in his body surged, and under the divine ability Total Annihilation, his combat strength erupted by a hundred times.
His spiritual essence and physical strength fused into one as he punched Tang Shiyi's chest again.
Bang!
With a muffled sound, Zhou Shu's punch hit the target. However, it didn't land on Tang Shiyi's heart but on his arm.
It had to be said that Tang Shiyi was indeed worthy of being a Grotto-Heaven expert. Even though he had been caught off guard and ambushed by Zhou Shu, his reaction was extremely fast, and he blocked Zhou Shu's second move.
Bang bang bang!
Thunderous thumps echoed in the torture chamber. Zhou Shu's and Tang Shiyi's fists and feet kept colliding. Their movements were so fast that they were almost invisible to the naked eye, and the force they released shattered all the torture tools in the torture chamber.
Zhou Shu felt that all the bones in his body were about to break, but he didn't dare to stop. He gritted his teeth, activated the Eight-Nine Arcane Art, and punched and kicked with all his might.
Tang Shiyi's situation was no better than Zhou Shu's.
He groaned inwardly. Zhou Shu's sneak attack had almost blasted away all his spiritual essence.
Otherwise, why would he be so passive?
His cultivation clearly far surpassed Zhou Shu's.
It was too aggrieved to be forced to fight him head-on.
Boom!
The two of them exchanged punches, and each took a step back. Zhou Shu finally couldn't help spitting out a mouthful of blood.
Tang Shiyi also spat out a mouthful of blood. Only now could he catch his breath.
Boom!
A powerful aura rose from Tang Shiyi's body as he took a deep breath. His spiritual essence cultivation, which far surpassed Zhou Shu's, finally erupted.
Zhou Shu's expression was cold, without the slightest bit of fear. He pounced forward.
Tang Shiyi sneered. A martial artist at the Earth Immortal realm actually dared to ambush him and almost succeeded. If others found out, it would be extremely embarrassing!
Tang Shiyi had no intention of alerting others. He raised his hand and pressed down on Zhou Shu.
Zhou Shu didn't dodge and allowed Tang Shiyi's palm to land on his chest. Surprise flashed across Tang Shiyi's face. He even heard the sound of Zhou Shu's ribs breaking.
But the next moment, his expression froze.
"You…" He looked at Zhou Shu in horror. Before he could say anything, he felt the spiritual essence in his body recede like a tide. Then a strong force came, and he hit the thick wall of the torture chamber with a bang.
Swish!
The sound of chains came, and the chains locked Tang Shiyi tightly. He was pressed against the wall and slid to the ground.
Tang Shi spat out a mouthful of blood. He lay on the ground and stared at Zhou Shu in disbelief.
"That's impossible! This is my Xu Ling Grotto-Heaven's Divine Lock Chain. How can you break free? How can you control it?!" Tang Shiyi shouted.
He regretted building the walls of the torture chamber so thickly that his voice couldn't be heard outside.
Now, no matter how loud he shouted, no one would save him.
"There's nothing impossible." Zhou Shu took a deep breath and endured the pain as he reconnected his broken ribs.
In just a short moment, he felt even more tired than fighting the Demon Realm army.
Tang Shiyi was a genuine Grotto-Heaven expert. Fighting a Grotto-Heaven expert in such a small space, he would have died on the spot if he wasn't careful.
If Tang Shiyi hadn't underestimated him, Zhou Shu would probably be dead now. Even so, his injuries were not light.
"Your biggest mistake was to try to trap me with a divine weapon," Zhou Shu said coldly.
Be it Tang San, Tang Qi, or Tang Shiyi, they would never have thought that Zhou Shu had the Legendary Armament Canon!
When he encountered the Reincarnation Mirror, he had discovered that the Legendary Armament Canon could record the Reincarnation Mirror.
Under such circumstances, even though he hadn't forged the Reincarnation Mirror personally, he could directly refine it.
When he was locked up by Tang Qi's Divine Lock Chain, Zhou Shu had tried to use the Legendary Armament Canon to intimidate the God Binding Chain. He found that when the God Binding Chain encountered the Legendary Armament Canon, it was like a mouse encountering a cat.
Although it wasn't recorded in the Legendary Armament Canon, it was no longer a problem for him to break free and control it.
Zhou Shu only erupted after enduring until he was in the torture chamber. As expected, the effect was miraculous.
Had he exposed this secret in advance, he could at most escape from the Xu Ling Grotto-Heaven. It would have been impossible for him to capture Tang Shiyi alive.
"Hmph, so what if you've broken free from the Divine Lock Chain?" Tang Shiyi looked at Zhou Shu and snorted. "It's impossible for you to escape from the Xu Ling Grotto-Heaven!
"Not to mention the Xu Ling Grotto-Heaven, as long as you walk out of the torture chamber, you will immediately be discovered. At that time, with your shabby cultivation, you will immediately be captured!"
Although Tang Shiyi was controlled by Zhou Shu, he didn't panic. His torture chamber was located at the core of the Xu Ling Grotto-Heaven. It was impossible for Zhou Shu to escape!
