I, a prison guard in the Heavenly Prison, secretly became invincible thanks to the system.

Lingyin Temple, a secret realm of heaven and earth, within the Azure Scale Treasure Vault, requires three great merits to unlock the opportunity to exchange for Lingyin Temple.

Ye Kang had seen this name before when he examined the Azure Scale Treasure Mirror, and he had a strong impression of it.

Unexpectedly, Dai Huanhuan's master was active in that area.

Ye Kang took a deep breath and narrowed his eyes slightly.

Lingyin Temple is located in the Qiantang area of ​​Jiangnan. To the north is the Jinling area, and to the left is the Poyang Lake. The distance is not far.

Regardless, we caught him ourselves, and now that he's escaped, we have to go there.

Ye Kang made a decision quickly, but he wasn't in a hurry.

The Demon Furnace will take a few more days to complete its refining process. Ye Kang judged that the furnace should refine dragon blood for body tempering, and with the jade lotus root on his body, his physical body would definitely see a significant improvement this time.

He immediately bid farewell to the two guards and headed straight for the Overlord Spear Sect.

In truth, these smaller sects all benefited greatly from this great battle.

When a whale falls, all things are born.

After the Thousand Absolutes Sect was destroyed, Yunhe, Longyue, and others secretly stole countless secret manuals from the sect. Xiyuan Town Guardian turned a blind eye, considering it payment for their help.

Of course, except for the poor Iron Fist Sect.

Most of the experts in the sect were forced to take the Dragon Transformation Pill as a test subject, and then they were all taken away by the Flood Dragon Lord in one fell swoop.

Another day of running around.

Ye Kang arrived at the territory of the Overlord Spear Sect without stopping.

This was also an island, but not far from the shore, separated only by a strait. Before Ye Kang even set foot on the island, a disciple of the Overlord Spear Sect rushed over and asked, "Is this Lord Ye Kang?"

"it's me."

"Great! Lord Ye has finally arrived. Please follow us."

Several disciples had already received instructions from Gu Lingwei and were specifically assigned to guard this place.

Ye Kang followed without hesitation.

Soon, he arrived at a pavilion where Gu Changlin and Gu Lingwei were waiting.

Gu Changlin said, "Lord Ye, I am sorry for not welcoming you properly."

"Sect Leader Gu, you're too kind. I do have a favor to ask of you."

"Not at all. With those four green thunder bamboos, you can borrow the Thunder Spring at any time."

"Uh……"

Ye Kang thought to himself, "I haven't even admitted that I am Wang yet, so how come you've already made that assumption on your own?"

Seeing his expression, Gu Lingwei smiled playfully and said, "What are you waiting for? Come with me, I'll take you inside."

"Thank you very much, Miss Gu."

Ye Kang followed him into the attic. As they went further in, a tunnel extended from the attic, connecting to a small hill on the island.

After passing through the tunnel, the view suddenly opened up to a deep pit, which appeared columnar from the outside, but inside was a boiling hot spring.

Gu Lingwei said, "This is the Thunder Spring, the foundation of our sect. I comprehended the thunder technique here. Last time, I used your Azure Thunder Bamboo to activate the underground thunder field here, which helped me break through."

"Isn't this a hot spring?" Ye Kang asked in confusion.

Gu Lingwei smiled and said, "Don't underestimate this place. This spring doesn't connect to the Great Swamp, but rather goes through the heart of the island and directly underground. You'll understand once you soak in it for a while."

"I see. I won't stand on ceremony then."

Ye Kang didn't care about anything else and strode into the hot spring, finding a spot near the center to sit down cross-legged.

Gu Lingwei murmured, "Ye... Wang..."

She smiled knowingly and left alone, leaving Ye Kang space to cultivate.

Inside the Thunder Spring, Ye Kang had barely sat down when a sudden current surged from the water and pierced his thigh.

A tingling, numb sensation flashed through Ye Kang's mind, greatly shocking him.

"What the hell! There's electricity in the water?!"

Before he could react, countless electric currents shot up from the ground, forming surging arcs that leaped out of the water and enveloped the entire spring.

The surrounding stone walls also crackled with electric arcs, soon producing a series of crackling thunderous sounds.

It's outrageous that a small hot spring could suddenly start attracting thunder without warning!

But Ye Kang had no time to be surprised. He discovered that these electric arcs and lightning entering his body did not damage his tissue cells. Instead, they traveled through his meridians and muscles, constantly stimulating his body.

My body quickly went into a tingling state, like a sponge that had been soaked in water and swelled up. It was not uncomfortable at all, but rather incredibly pleasant.

Ye Kang sensed it for a moment, then used the Wolf Demon Transformation Light Technique and took out a piece of jade lotus root to eat.

Under the combined effect of these three factors, the physical body's strength is subjected to intense tempering, resulting in an effect that is more than three times greater.

His complexion visibly regained its rosy hue, and even some of his still-healing physical injuries began to gradually improve.

magical!

Amazing!

This is truly a treasure trove for body tempering!

Ye Kang was overjoyed and began to frantically use lightning to temper his body.

……

Four days passed quickly.

Ye Kang slowly opened his eyes in the hot spring.

At this moment, he had transformed into Guan Yu, his face flushed red, but his expression was one of utter bliss.

He let out a long sigh: "Awesome!"

After four days and four nights of tempering, he absorbed all five sections of the jade lotus root at an incredible speed, without wasting a single bit.

His physical strength has increased by at least 30%. If before it was only equivalent to the ninth rank of the initial stage, now it has firmly surpassed the initial stage.

"It's a pity that as the days go by, the lightning is becoming thinner and thinner. The lightning field here will probably need time to form. Well, that's fine, the time is almost up."

Ye Kang stopped tempering his body, and with a thought, the system panel appeared before his eyes.

He clicked on the Demon Furnace and saw that the refining progress had reached 99, entering the countdown stage.

Ten days of waiting, all for this final sliver of hope.

"Come on, let me see what a ninth-grade Flood Dragon Lord in the Middle Realm can refine!"

Ye Kang rubbed his hands together, and the countdown stopped simultaneously.

……

Ta-ta-ta-ta!

The sound of gold coins exploding rang out wildly, and system notifications kept popping up, dazzling Ye Kang's eyes.

He held his breath, his expression one of ecstatic joy.

"Wow! So many gold coins! No wonder it's the Flood Dragon King, Niu Ben is really something else!"

Ye Kang laughed heartily.

We've struck it rich! We've really struck it rich! There's so much stuff we can't even count it all!

"A full 28 demon blood crystals! How many low-level demons would it take to refine that!"

Ye Kang was almost in tears. He had refined a snow-backed wolf, and the number of demon blood crystals he could obtain was less than ten. This was the difference!
