"It’s no wonder it’s a thousand-year-old turtle; its hardness has reached an unimaginable level!"

Su Xuan once again circulated his Dark Strength, attempting another stab, and only then did the sword barely pierce the turtle’s shell. Even then, it couldn’t completely penetrate it.

After slicing open the turtle’s belly and completely removing the shell, he looked at the massive shell, about the size of a table. Su Xuan used his Heroic Sword to cut around the shell, eventually leaving only a piece the size of a washbasin. Su Xuan knew this part was still extremely hard, the essence of the entire shell. A thousand-year-old turtle was indeed very formidable, and its hardness was beyond question.

"Tianyi, this is for you!"

Su Xuan handed this piece to Luo Tianyi!

"What do I need this for?"

Luo Tianyi was curious, thinking why would he give this to me, and what could I do with this?

"Silly, this thing is very precious. Don’t underestimate it!"

Su Xuan nervously smiled as he spoke. This hardest part, even with his Heroic Sword, might not be pierced, so its preciousness was evident.

"Oh, well then!"

Luo Tianyi took the piece and muttered to herself, thinking he wouldn’t use this for divination, right? Some people used to do that!

"Big Brother Su, what should we do now?"

After their clothes dried and they warmed up by the fire, their bodies regained some temperature, but he really didn’t know what to do next.

"Let’s find an exit. They don’t know how wide the underground river is and are likely trying to open the tomb chamber doors above. Who knows when they’ll find us here. Instead, why not find the mechanism ourselves, unlock it, and break out from within!"

Su Xuan felt a strong urge to swim back through the underground river, but after reconsidering, he felt it was unwise. The underground river might have pitfalls or water pressure issues. Even if he managed to use his Dark Strength to swim back forcibly, it might not work if he took Luo Tianyi with him. The water flow was too strong, and they couldn’t withstand it.

With a flashlight, Su Xuan shone a strong beam on the walls around him. Having no other choice, he decided he’d better play the role of a tomb raider once, otherwise, they would remain trapped. That wouldn’t work.

As the strong beam illuminated the surroundings, Su Xuan pressed his palm against the wall, circulating his Dark Strength. After it flowed through, he discovered nothing unusual. Rubbing his forehead, he thought this better not be a dead cell with no exit.

Su Xuan rubbed his nose, drew out his Heroic Sword, and slashed away continuously.

"Zheng zheng zheng..."

In that moment, dozens of sword lights swept out like meteors. With the flowing sword light, stone fragments burst from the stone wall, debris flying everywhere. Even as the wall was thick, Su Xuan’s frenzied swordsmanship shaved off its entire first layer.

"Unbelievable!"

Watching huge pieces of stone fall off like that shocked Su Xuan. He knew his Heroic Sword was powerful, but not that it could cut through like this. It felt as if the stones were weathered, breaking away continuously.

"Big Brother Su, there seems to be writing on the stone wall!"

At this moment, Luo Tianyi spoke up excitedly. Su Xuan, feeling curious himself, shone the flashlight upward and indeed saw characters on the wall.

"It seems to be a sword technique!"

Curious, Su Xuan realized that he had cut not bare rock, but something cast over it later on.

"Is it Kung Fu?"

"Yes, something like that. It’s funny, ancient people carve this on the wall, but don’t want anyone to see it. Isn’t that contradictory?"

Su Xuan clicked his tongue, shining the flashlight up. Indeed, the wall was inscribed with a swordsmanship called Ruoshui Swordsmanship.

Being skilled in swordplay, Su Xuan could understand the techniques carved on the wall!

"Is the swordplay impressive?"

Luo Tianyi watched Su Xuan study the wall intensely, intrigued. Luo Tianyi was skilled in leg techniques, not swordplay. Nowadays, few could truly claim expertise in swordplay.

As the saying goes, "A hundred days to master a blade, a thousand days to master a sword," as swords are the utmost among weapons. So, true swordsmen usually had remarkable Kung Fu.

Having seen Su Xuan wield a sword, she knew how effortlessly and gracefully he moved, making the sword an extension of himself—it was truly captivating.

"Yes, it’s amazing. Our Huaxia has a civilization spanning thousands of years, with deep insights into swordplay. Unfortunately, much of it has been lost over time."

Seeing the sword moves on the wall excited Su Xuan; these were authentic sword moves, unlike the incomplete techniques he knew. The Jinghong Sword Technique taught to him by the Military God was only partial—many complete moves were lost.

Su Xuan never expected to find actual sword moves here in the ancient tomb, hidden on a wall.

Reading the Ruoshui Swordsmanship on the wall, Su Xuan guided his Dark Strength according to the instructions, causing a flow of Dark Strength to transform into Sword Qi within the Heroic Sword. Unconsciously, Su Xuan started to move, practicing Ruoshui Swordsmanship, the moves flowing like water, flexible and straight.

As he executed the technique, the Ruoshui Swordsmanship produced droplets that seemed to fall into a pool, emitting clear plop sounds; it was truly delightful.

In the tomb, Su Xuan moved continually, his Heroic Sword thrusting quickly and repeatedly. As each thrust was executed, the sound of bubbling water was enchanting.

Beside him, Luo Tianyi watched, her eyes wide with wonder. She never imagined such an exquisite swordplay existed in the world.
