"If this bronze cauldron is used properly, it will be an unprecedented lethal weapon!"

In a secluded cave, Jiang Ming held the bronze cauldron in his hand and observed it.

He had been refining this bronze cauldron for more than two days. He used his divine will to remove all the other seals on the cauldron and left his own seal on it. He had complete control over the cauldron and had almost figured out how to use it.

"This is definitely the most powerful magic tool I have obtained other than the black sword."

When the bronze cauldron erupted with its full strength, it could easily devour the vitality and spiritual energy of a cultivator at the peak of the Foundation Establishment Realm. Even a Golden Core Realm cultivator would probably suffer a huge loss if the green light swept over them.

Of course, a Golden Core Realm cultivator would not stand there foolishly and take on such a terrifying force. Therefore, it was still somewhat unrealistic to really use this thing to kill a Golden Core Realm cultivator.

"However, to me, it's a trump card. Unfortunately, the energy in this bronze cauldron has been exhausted and needs to be replenished."

Jiang Ming sent his divine will into the cauldron. It was empty inside. Although the mysterious and terrifying runes still existed, it had almost lost all its power.

This kind of power was obviously not something that ordinary spiritual energy could replenish. It needed the essence and vitality of living beings to nourish it.

Jiang Ming took out a spirit herb from his storage ring and threw it into the bronze cauldron. Then, he shook the bronze cauldron slightly and instantly refined the spirit herb.

Threads of vitality entered the bronze cauldron, causing it to flicker slightly before returning to silence.

"It seems to be somewhat useful. However, this is just a drop in the bucket," Jiang Ming said softly. He felt that the dried energy source in the bronze cauldron had strengthened a little. However, it seemed to be far away from being able to unleash its full strength.

Ordinary spirit herbs did not seem to have much effect on this bronze cauldron. However, Jiang Ming was a little reluctant to use rare spirit herbs on it. Who knew how many spirit herbs this bottomless pit would devour? Moreover, if it was used again, it would require a huge number of rare resources to replenish it!

"No wonder only those major forces can refine this kind of secret treasure. Otherwise, the price is too high. Ordinary cultivators can't afford to refine it, nor can they afford to use it," Jiang Ming said softly. However, he revealed a smile. The other secret treasures were fine. However, this bronze cauldron seemed to be tailor-made for him.

He activated the bronze cauldron again. This time, it began to devour his essence and vitality.

The bronze cauldron was like a shark that smelled blood. It immediately trembled and emitted bursts of light. A large number of decaying runes erupted and swallowed Jiang Ming.

"As expected!"

Jiang Ming's eyes were calm. He had already expected this outcome. What kind of essence could compare to the essence of an immortal cultivator?

In just an instant, Jiang Ming felt that his essence, vitality, and divine soul were being devoured crazily. His entire body withered in an instant, turning into a dried corpse that was only skin and bones.

However, at the same time, the indestructible origin light seemed to have been provoked. The surging light spread out and enveloped him. The vitality that was as vigorous as the ocean filled his entire body. His body instantly recovered to its original state.

The bronze cauldron was like an angry dog that had broken free of its leash. It kept erupting with terrifying power. Jiang Ming could not even control it at this moment. If it were not for the indestructible origin light, he would have been sucked into a dry corpse at the first moment.

However, Jiang Ming could finally feel that the dried-up power in the bronze cauldron was quickly filling up.

With this speed, he would probably be able to completely replenish it in less than an hour.

"It really is a demonic item." Jiang Ming's gaze was a little solemn. At this speed, even if there were hundreds of Foundation Establishment Realm cultivators, they would be completely sucked dry.

One could imagine how much the Cangming Grotto-Heaven had paid to refine this secret treasure. The cultivation resources it had consumed were probably massive.

"It is essentially a forbidden tool!" Jiang Ming muttered to himself. He had practiced many forbidden techniques, but this was the first time he had obtained such a forbidden tool.

After a few days of refining, Jiang Ming had a faint premonition that the upper limit of this forbidden tool was far from this. The Cangming Grotto-Heaven had hardly put a dent in it.

"If this bronze cauldron were to reveal its original appearance, wouldn't it be even more terrifying?" Jiang Ming whispered. However, he did not act rashly.

Although he was immortal, this thing could instantly suck him dry. If the seal was removed and the explosion was completely unleashed, it might even destroy his physical body.

"Perhaps I can only unleash its full power when I become stronger in the future!"

Jiang Ming played with the bronze cauldron and became satisfied with it.

"Hmm? Someone is approaching!"

Jiang Ming suddenly got up and rushed out of the cave, looking at the misty valley ahead.

"I have not seen anyone for the past few days. I wonder how the group of people from the Qingyuan Sword Valley is doing. Is Wu Hen still among them?" Jiang Ming said softly. He moved and silently headed toward the valley.
