Zhao Yuan also saw the dripping 'blood and sweat' coming out of his body. However, he knew that it was neither blood nor sweat, but the essence substance that had been polluted in his body!

The first step in cleansing the marrow is to expel them from the body to make way for the new essence substance.

The so-called old does not go to the new and does not come, this is the truth.

With the discharge of the contaminated essence substance, a series of crushing severe pains appeared all over his body, making Zhao Yuan feel that his limbs and internal organs were as if they had been crushed back and forth by a 10,000-ton road roller, breaking and crushing inch by inch!

The pain suffered while cultivating the Four Sacred Techniques was completely incomparable to this inhuman torture at this moment!

If it weren't for Zhao Yuan's knowledge that 'the heavens will descend on the people, they must first suffer their minds, strain their muscles and bones, and starve their bodies and skin', plus in the introduction of the pulp washing technique, I saw such a passage - the first time he practiced the marrow washing technique, he would suffer incomparably severe pain, and he needed to grit his teeth with great perseverance to persevere--I am afraid that he would have given up a long time ago.

"I didn't expect that washing the marrow turned out to be such a feeling. Zhao Yuan, who was enduring the severe pain, gritted his teeth and gurgled, and his facial features were tightly wrinkled together, making him look as hideous as a ghost.

He gasped for breath while cheering himself up in his heart: "Persistence! You must persevere! If I can't even pass this level, what qualifications do I have to embark on the path of a witch doctor? I'm a man who wants to be a witch doctor! How can I be knocked down by a little marrow washing?"

Since he received the inheritance of Wu Peng and embarked on the path of cultivation of the witch doctor, Zhao Yuan's harvest was something he had never dared to think of before! This not only made him firm in his desire to continue cultivating, but also made him full of longing and expectation for the way of the witch doctor!

Under such circumstances, as long as Zhao Yuan still has a breath of air, as long as his life is not extinguished, he will persist in walking! No matter how great the pain he endures, no matter how many dangers and obstacles he encounters, he will not give up and will not stop moving forward!

However, Zhao Yuan didn't know that Wu Peng's introduction to the marrow washing in the inheritance was actually concealed.

After stepping into the marrow washing, everyone will experience this kind of severe pain and torture! And this torture is endless, and it will continue until people can't bear it anymore and pass out!

The reason why Wu Peng concealed this introduction in the inheritance was to see how long Zhao Yuan could hold on without knowing it!

Because under the torture of severe pain in the marrow washing, the longer you persist, the farther you will be able to go in your cultivation in the future!

This kind of torture is a test!

Not only for talent, but also for willpower!

In practice, talent is very important, but willpower should not be underestimated!

This is because the path of cultivation is never smooth sailing, but is full of twists and turns, thorns, difficulties and obstacles. If you don't have extraordinary willpower, even if you have the best talent, you can't achieve much!

The longer you persist in the torture of marrow washing, the stronger your willpower will be, and the higher your qualifications!

If you persist for a minute, you will be qualified to practice.

If you persist for three minutes, you are medium qualified, and if there is a big opportunity, it is not impossible to become an immortal!

If you persist for more than 10 minutes, you will have the best qualifications! This kind of person has always been regarded as a genius in the cultivation world, and is the object of contention among the major sects! Just like the champions of various provinces in the college entrance examination, they are the targets sought after by major colleges and universities!

Zhao Yuan didn't know anything about this, he still thought that this torture was the same as cultivating the Four Holy Tips, there was a time limit, as long as he survived, he would be able to turn bitterness into sweetness!

However, time has passed extremely slowly in this process.

Finally, a minute passed.

Zhao Yuan's face was as white as paper, panting, but he was still clenching his teeth, and he was desperately persisting while urging the pulp washing technique.

Three minutes passed.

A large pool of crimson essence substance was formed under Zhao Yuan's feet, and his strength had already been hollowed out, and his legs were trembling incessantly, and he could fall down at any time due to exhaustion. Even so, he still persevered!

Ten minutes passed.

Zhao Yuan's brain was already blank, and his internal organs had become extremely weak under the double torture of crushing pain and blazing heat, so that his breathing, heartbeat, and other vital signs were all sharply weakened and decayed!

But he still insists and refuses to give up!

There is only one thought in the blank brain, and that is: persistence, persistence, persistence!

The clock goes on.

Fifteen minutes...... Twenty minutes...... Thirty minutes......

Thirty minutes! In the cultivation realm, for thousands of years, there are only a few hundred people who have been able to endure the inhuman torture of washing the marrow for so long! And these more than 100 people, except for a few who died young, the rest have all become famous figures! Even the lowest level has reached the level of the Supreme True Immortal!

Zhao Yuan is still insisting and continuing!

Forty-five minutes have passed! This is the record set by Wu Peng when he was washing the marrow!

Zhao Yuan no longer has a human appearance at this time, and his heart, breathing, and other data have all been reduced to a minimum! If he were an ordinary person, he was afraid that he would have already died. But under the effect of the turtle breath of the Four Holy Recipes Xuanwu, he persevered, and continued to grit his teeth and bear the torture!

"Persistence...... I don't believe it...... I can't carry the moment it ends......"

Zhao Yuan felt a burst of blackness in front of him, and a strong feeling of suffocating shock came to his heart, he had no way to stop it, he could only keep cheering for himself in his heart and continue to persevere!

Forty-six minutes......

Fifty minutes......

Fifty-five minutes......

After the painful torture of washing the marrow lasted for a whole hour, Zhao Yuan couldn't bear it anymore, his body trembled for a long time, and finally fell to the ground with a 'plop', his eyes were dark, and he fell into a coma!

At the moment of coma, Zhao Yuan sighed with great regret: "It's still a failure...... It seems that my achievements in cultivation should not be too high, hey, I am afraid that my talent will live up to Master Wu Peng's expectations. ”

Thanks to him, he is the only one in this factory, and there is no cultivator here, otherwise he would have to vomit blood by his words!

You've been fucking persevering for an hour in the torture of washing the marrow, and you're still saying that your talent isn't good enough? Don't you pretend to be so forced! If you're not good enough, then what are we? Are we rotten to the point of scum? Please, it's good to recognize the reality, you're clearly a super demon with a talent so good that it's against the sky!
