At night, Lu You came to the back mountain alone to meet the old ancestor, which was also the beginning of the devil's trial.

The back mountain is also behind the Ghost Spirit Mountain, there is a hidden small peak and a small valley, where you can start the trial, presumably this is also the place where the Xi Lingxiao and the West Vulture brothers tried before.

After Lu You came to the back mountain, the Shengyuan Sword began to sense, and Lu You knew that this should be the ancestor nearby, so he walked over quickly.

"Little one, you're pretty early!"

On a hill, Xi Lingxiao was drinking strong wine with a wine gourd, eating roast chicken, looking happy and comfortable, Lu You didn't feel strange about this, Liu Yun could eat fruits at the beginning, so when he reached a certain level of ghost cultivation, he didn't have to worry too much about it at all.

"Ancestor, did I come early? I feel very late!" Lu You came over after dinner, and this dinner was also very tormenting, rumors that others knew, not to mention Ma Xiaoling.

So Ma Xiaoling looked at herself, like a husband who had done something bad, and Ma Xiaoling was the wife of a scrutinist, which made Lu You very helpless, and he couldn't stand Ma Xiaoling's questioning and resentful eyes, so he could only leave.

It should be around nine o'clock in the evening, and Lu You's mobile phone has long been out of battery, so there is no way to see the time here, and the world in this does not need a specific time to live, it is all judged by the rising and setting of the sun.

"Little guy, you look inside!" Xi Lingxiao Old Ancestor didn't say too much nonsense, but pointed to a group of stones on the opposite side for Lu You to see.

Lu You naturally followed his gaze and looked over, and then he was stunned, looking at those stones, each stone was deeply dented, but it was not broken, which made Lu You very surprised.

Lu You, who had quickened his pace, walked directly to the middle of this group of stones, looking at the surrounding stones, the stones that were not very good-looking were not very large, but each stone had a fist imprint, a very deep imprint.

And what is incredible is that the imprints of these fists are all sand and dust, which means that no one has used them for a long time, but I am afraid that it has exceeded a hundred years.

At this moment, the voice of Xiling laughing at the old ancestor came into Lu You's ears.

"Little one, this is the stone I hit when I was tested with my brother West Vulture. ”

"At that time, our father taught us so harshly, every stone had to be grooved at least ten centimeters deep before we could go home for dinner!" Xiling smiled with a complicated gaze, as if he missed that time.

When Lu You heard this, he was also deeply shocked, a ten-centimeter groove requires at least 10,000 catties of strength.

"Little guy, don't you think it's unlikely?" Xi Ling smiled, looking at Lu You, his eyes were full of expectation, he seemed to see their shadow in Lu You's body, no, it was a shadow with a future talent than them.

This kind of person should be like his father, and go to that mysterious and more powerful place, right?

It's not just going to be here!

"Old Ancestor, do you think it's possible?" Lu You smiled bitterly, feeling very helpless, he had to make a pit of more than ten centimeters in a short period of time, which was somewhat unlikely.

"It's okay, you practice slowly, if you can't make a groove of at least three centimeters in a stone tonight, I'll let you move the stone tomorrow!"

"If you can't do it in a day, you can add an extra thousand pounds of stones, and so on!" Xi Ling's smile had long since frozen, replaced by a look of indifference.

Lu You understood, this is the devil's training method, to force his potential in this way, his previous self was still too comfortable, even if the cultivation speed is very fast, it is only the kind of cultivation that stops at the surface.

But this time, it is a real tempering to the bones, but this kind of tempering is also what Lu You needs most.

"Okay old ancestor, I will work hard!" Lu You didn't have time to talk nonsense, standing in front of a three-meter-high and five-meter-long stone, clenched his fists and began to charge his strength, mobilizing spiritual power and demonic power at the same time, fusing into his fist.

Gradually, I found that my fist had begun to turn red, and the power of these two energies after fusion was bound to be terrifying, and even the air seemed to smell a dangerous breath and turned into a vacuum area.

Three!

Two!

One!

After Lu You silently recited the numbers in his heart, he was ready to smash it with a punch.

"Stop!"

But suddenly, he heard the angry sound of Xi Ling's laughter, which made Lu You's whole body instantly unload, and it was difficult to accumulate the same strength for the second time.

"Little guy, you are not allowed to use spiritual power and demonic power, this is just cheating, and you can't really train your strength!"

"From now on, you can only use demonic power or spiritual power to exercise, think for yourself, if you can, accept my challenge, if you can, go back to sleep!" Xi Ling's voice was very harsh, and his tone was also very harsh, which made Lu You's face very heavy, but he didn't feel angry and humiliated.

The ancestor is right, if he can't even challenge this difficulty, how can he challenge Nalander in the future? How can he challenge Hu Jiayu, if he can't even beat these two people, how can he challenge his rival Snake Emperor Gao Wentai?

Not to mention Xin'er's high expectations and high requirements for himself, so for them, he must also insist.

"I won't give up, Ancestor!" Lu You clenched his fists, this time there was only one kind of power, and that was spiritual power.

His spiritual power is relatively demonic, and it is still weaker, so he needs to exercise his spiritual power first.

Bang!

After clenching his fist, he smashed it hard, and the dull sound of banging after the punch went down made Lu You's fist numb to the point of numbness, but Lu You gritted his teeth and continued to insist.

Bang!

Bang bang bang!

One punch after another hit the stone, leaving a trace on the stone with each blow, but before it reached the three-centimeter standard, Lu You knew that his extreme had not yet been reached.

I want to use the big move in the Fuxi Gong Method.

"You are not allowed to use ultimate, you must use your own spiritual power to fight!" Xi Lingxiao warned Lu You again, so that Lu You had no choice but to give up this shortcut.

It's true that way is cheating, if you use the exercises, let alone hit this stone ten centimeters, even if it is smashed, it is not difficult, but what is needed is real strength, ** power.

"Okay, Old Ancestor!" The fine sweat on the Old Ancestor's head had already flowed down his cheeks drop by drop, and if he didn't know, he would have thought that Lu You had been trained to cry.

Lu You gritted his teeth and persevered, but there was a sharp pain like broken bones in his fists, and the pain in his five fingers was the same

But Lu You has never been timid, since he has chosen to train himself in the same way as the old ancestor devil, he will definitely not be able to live up to him, nor can he live up to himself.

"Xin'er, your man will definitely become very strong, when I go out, I must take you back to me, that Gao Wentai can only be trash!" Lu You clenched his fists, and his heart was full of anger.

Click!

With one punch, Lu You pierced the stone, and the superposition of one punch and one punch after another had already made the stone not hit, so it would inevitably shatter at this moment.

Of course, this boulder was only pierced in one place, and the rest of the places were still intact, so Lu You continued to beat the stones.

The thumping sound sounded a little heart-wrenching, and my teeth felt numb.

But Lu You was very happy, he had gradually liked this beating rhythm, and he didn't want to stop, and his fist had become numb because of the impact on the stone, and he gradually lost consciousness.

There is no conscious hand, but it is more powerful, this is what the ancestor of Xilingxiao wants to achieve for himself.

An hour, two hours, five hours

In six hours, Lu You made four or five holes, and the entire stone was also pierced through several holes.

Seeing this, the old ancestor of Xi Ling smiled with a smile on his beard and satisfaction: "This kid is very similar to his brother back then!" Xi Ling laughed and muttered, Lu You has the shadow of the West Vulture on his body, but he is younger and has a future than the West Vulture.

Bang!

There was another sound, but it was Lu You who smashed the entire stone, turning it into countless pieces and falling to the ground.

Seeing this, Xi Lingxiao was just about to speak, when he saw Lu You lying on the ground with a bang, so tired that he collapsed!

"Hahahaha!" he laughed insolently, feeling that Lu You had done his best, but it was far from enough

"Get out of here, move on to the next bigger and thicker boulder, and repeat!"
