Om! Under the burning of the flames, you can see that the coffin that originally looked extremely strong, like a ball of purple gold immortal iron, began to gradually change from purple gold to red.

This looks like a piece of mortal iron, experiencing being tempered.

During the color change, Wang Teng could clearly feel that an extremely powerful backlash power came from the purple gold divine iron, as if there was an invisible big hand pressing towards Wang Teng's heart.

Wang Teng maintained the posture of urging the flames of the universe mother cauldron and burning the purple gold divine iron. His body gradually trembled slightly, and he felt like he was carrying a huge invisible sacred mountain on his shoulders, which made his face slightly pale, and there was a row of fine sweat on his forehead, which emerged.

"This backlash is really great."

Feeling this backlash, Wang Teng couldn't help but bit his teeth a little, and some slightly difficult sounds popped up from his teeth.

If it weren't for his good strength, even if others could activate the universe mother cauldron, they would definitely not be able to withstand this backlash. The bones in their bodies might be crushed and completely destroyed.

"However, this is also a test for you. It can make the divine power in your body more pure, thus making your strength reach the level of improvement."

The Great Ming Tianzun chuckled and said.

Stress is always a way to make progress.

The more pressure and hardships you will endure, the greater the level of progress will be.

With Wang Teng now, it is not easy for him to improve.

This is a good ordeal.

I'm afraid it will not only temper the divine power, but also the soul and body.

Speaking of which, this is not a bad thing.

With a bitter smile, Wang Teng could only comfort himself. Then he clenched his teeth tightly, his mind was highly tense, and the purple flames of the universe mother cauldron were constantly activated, burning purple gold divine iron. This kind of soul, body, and divine power were constantly persevering when he was suffering.

With this persistence, he was able to discover the slow growth rate of his soul, body, and divine power under this tempering.

This made him feel a hint of joy.

Time passed by like this while Wang Teng was suffering a little. After about three hours, Wang Teng's face had become extremely pale, like a sponge wrung out of moisture, without any blood. The sweat on his body had wet his clothes, and even the veins on his forehead appeared slightly.

At first glance, it smells like a hideous and terrifying smell.

Although this kind of tempering will greatly improve his physical fitness, it is obviously very slow and far from keeping up with his consumption.

Now he is like a mortal, carrying a mountain on his back, and has reached the limit of persistence.

His feet stood on the solid rocks, and his calves were constantly trembling.

"It's almost done."

Seeing Wang Teng's miserable appearance, the Great Ming Tianzun felt a hint of unbearableness in his heart, and then said anxiously.

It was seen that the coffin in front had completely turned red at this moment, like a red-burned soldering iron. The terrifying temperature in it made the space ripple rapidly. At such a high temperature, the Great Ming Tianzun did not doubt at all. I am afraid that even an ordinary quasi-divine weapon would instantly turn into a ball of liquid and be damaged.

Staring at the coffin, the Great Ming Tianzun could clearly feel that there was a special energy in it, which was also burned to death. When it completely disappeared, it must be the time when the coffin, which was integrated, was completely opened.

Speaking of which, Wang Teng is not burning the coffin, but the energy in the coffin.

If they knew the method to open it, they could open the impure coffin effortlessly. Without knowing it, they would have to use this most primitive and clumsy method.

Hearing this, Wang Teng then forced himself to raise his spirits.

"Break it for me!"

Then, his teeth tightly clenched a little, and Wang Teng jumped out of his throat with a few words weighing more than ten thousand pounds. Due to his eagerness in his heart, he suddenly burst out with potential.

Boom! With the explosion of potential, the cosmic mother cauldron, which was slowly spraying purple flames and burning the purple gold coffin, was instantly like a volcano erupting, and more purple flames were sprayed out, causing the burning power to increase in a flash.

In an instant, the special energy that was already at the end of its strength was like the last straw that was crushed by a camel, and it was completely wiped out with a click.

Click.

Then, a crack finally appeared around the coffin, and the coffin lid hidden by a special method finally appeared.

"It's finally done."

Seeing this, Wang Teng breathed a sigh of relief, and his body felt as if he was so angry that his skin ball was exhausted. He smiled bitterly and fell to the ground, gasping for breath, without any movement.

It's too tiring to burn like this, it's even more tiring than fighting a super strong man.

He felt that the energy in his body had been exhausted and he had no strength.

"Haha, it's better to recover quickly. Recovering now is good for the body."

The Great Ming Tianzun chuckled.

Wang Teng was able to persevere until now, which made him very satisfied.

"Um."

Wang Teng nodded, unable to help but feel speechless. He never thought that just opening a coffin would be so tired that he couldn't help but curse.

After posing in a cultivation posture, his Great Swallowing Heaven Sword was circulating in his heart. Wang Teng's entire body instantly seemed like a big black hole, crazily absorbing the energy in the stone chamber.

As the energy entered his body, he felt his spirit, body, and soul gradually recovered, and this feeling of gradually being replenished was extremely comfortable.

Half an hour later, Wang Teng finally returned to his peak. His eyes opened, and a flash of light flashed away. The abundant power in his body made him feel refreshed and full of energy.

At this moment, he found that his physical fitness had indeed been greatly enhanced. His body was as light as a swallow, and he spread his body casually, as if he could float up.

"My current realm has reached the twenty-fifth level of the Quasi-Divine Realm."

After checking the realm, Wang Teng said excitedly.

"Haha, not bad, the strength has indeed increased."

The Great Ming Tianzun chuckled.

"Okay, now I want to see what items are inside this coffin."

Wang Teng stood up, looked at the coffin, and gritted his teeth.

This bastard made him so tired that he really wanted to slap him to smash it.
Chapter completed!
