Silence oppresses the night, and on the top of the mountain, there is only the merciless sound of the wind.

Leo sat down on the ground under the cover of black robes, and sat cross-legged on the hard and cold earth.

The ruffian dragon and Xiaohu stood aside, carefully listening to the wind and grass around them, and at the same time, they were also carefully paying attention to Leo's situation.

Changing the pulse is not trivial, since they can't help Leo much, they are also guarding the latter's side to prevent Leo from other accidents.

Leo sat in the darkness of the night, his eyes closed.

On the resolute face, the expression is rich and complex.

Perseverance is accompanied by apprehension, apprehension and expectation, and anticipation is mixed with fear.

Leo was afraid, he was afraid that he would fail.

Although he has absolute confidence in himself, the ruffian dragon also said that the process of changing the pulse is extremely difficult, and if you are not careful, you will fail.

The price of failure is that Leo has completely become a waste, and Leo can't afford this price.

And, in the face of unknown and mysterious things, the first emotion that comes to people is not curiosity, but fear.

The changing expressions on Leo's face also made the ruffian dragon and Xiaohu even more worried.

"Boy, you must succeed!" While the ruffian dragon cheered Leo, it seemed that he was also cheering himself and Xiaohu up.

Xiaohu's tiger eyes stared at Leo deadly, and his eyes were full of worry.

For as long as he can remember, Leo has appeared in Xiaohu's mind, and since then, Xiaohu has decided that Leo is the eldest brother in his life, and the eldest brother is like a father.

This is also why Xiaohu treats Leo so affectionately, and always unswervingly calls Leo his big brother.

"Big brother, you will definitely succeed, definitely!" Xiaohu's worried eyes were full of determination.

"Ah......h

Suddenly, a roar came out of Leo's mouth, and Leo's expression turned into pain.

"Big brother......" Xiaohu roared worriedly when he saw this.

"Second brother, what should I do?" Turning his gaze on the ruffian dragon, Xiaohu asked worriedly.

"What's the name of the ghost? The change of pulse has just begun. After reprimanding Xiaohu for a few words, the ruffian dragon said in a deep voice.

After the ruffian dragon finished speaking, he put his solemn gaze on Leo, and the dragon's claws were clenched, trembling slightly.

When Xiaohu saw this scene, he also shook his head and smiled, obviously worried, but he had to pretend that he didn't care so much.

Xiaohu's eyes fixed on the ruffian dragon for a moment, and then his gaze was on Leo again.

On Leo's forehead, the green tendons bulged, and the blood vessels all over his body swelled.

Leo's face was hideous, his muscles were tightly squeezed together, and even his body sitting cross-legged on the ground was shaking.

It shows that at this time, Leo is enduring an extremely terrifying pain.

In the sea of consciousness, Leo's soul power could clearly feel that when the Naling Pill melted down his throat into his limbs, an unbearable pain spread in every part of his body.

Even at this time, with the help of his soul power, Leo was able to see that green light appeared in his broken meridians, and those originally incomplete meridians were instantly turned into powder, and at the same time, a pain that almost made Leo faint came to his mind.

This pain was like crushing Leo's meridians alive, and it was like throwing Leo into a furnace alive, and then slowly burning it away.

Leo's consciousness is like a boat in the ocean, as if it will be extinguished in an instant, and like a flame in the night, as if it will be extinguished in the next moment.

Leo kept the last trace of clarity in the sea of consciousness, and continued to complete the process of changing the pulse.

However, at that moment, the pain like a broken bone kept eroding Leo.

The unbearable pain had caused Leo's consciousness to gradually blur, which also caused an extremely tempting voice to appear in the latter's ears:

"Go to sleep, sleep and you won't suffer so much anymore. ”

"Don't insist anymore, as long as you sleep, there will be nothing, you will have no pain, no confusion, you will always live in heaven. ”

"Persistence is meaningless......"

Leo's face was hideous, and he finally couldn't help but yell: "Get out!"

This loud roar also made Leo's vague consciousness finally a little clearer.

"No, I can't sleep. Leo said through gritted teeth, enduring great pain.

"I still have to take revenge, I have been suffering for a year, I have endured for a year, I racked my brains to finally obtain the life spirit vein, and I am about to succeed, I can't fall here. ”

"I also want to prove that everything my master has done for me is worth it, and I want to kill Gao Cheng and cut off all the gossip. ”

"I still have to practice the martial arts recorded in the Spirit Martial Arts, I can't fall, never. ”

"I believe that I will succeed, I will definitely be able to. ”

"No one can beat me, no one, including you. ”

"Ah......h

Leo's soul power has first been tempered by the ancient seal of soul purgatory, and then tested by the ancient tree of life, although he doesn't know what the test of the ancient tree of life is, but the ruffian dragon knows that that kind of test will never be simple.

Even though Leo's soul power has been honed so much, he still shows such a terrifying expression in the process of changing his pulse.

It can be seen how terrifying the pain Leo suffered at this time was.

Moreover, this pain did not diminish because of Leo's unbearable suffering, but continued to intensify.

Therefore, the ruffian dragon and Xiaohu also saw that the blood vessels exposed on Leo's face actually showed the slightest crack.

The moment the crack appeared, strands of blood were left on Leo's face.

His face was covered with blood, and combined with Leo's distorted and hideous face, the latter's appearance at this time was extremely devouring and terrifying.

Not only that, but Leo also had a lot of blood flowing out of his body.

Judging from the blood marks on Leo's neck, the ruffian dragon could tell that Leo's whole body was afraid of this.

"Hey, the difficulty of changing the pulse is terrifying. ”

Even though he was mentally prepared, seeing this kind of scene, the ruffian dragon couldn't help but gasp, his face full of horror and worry.

"Ah...... Ah......h

Thunder's screams came one after another, and in the ears of the ruffian dragon and Xiaohu, the heart was also like a knife, and the pain was unbearable.

"Boy, no one can help you now, you must give your Grandpa Long to hold on!" The ruffian dragon flew around in the air like an ant on a hot pot, and was so anxious that it was spinning.

But as he said, the process of changing the pulse is Leo's own business, and it requires a strong will to complete, and outsiders can't give any help.

Not to mention that the ruffian dragon had not recovered from his injuries at this time, even if he returned to his peak state, it would not be able to help Leo come out of the pain.

This is the strength of the Heaven and Earth Spirit Creatures, but if Leo can carry it, after the successful change of pulse, he will also obtain unimaginable benefits.

"So, boy, if you can carry it this time, your future achievements will be to run on the mainland, and you will have some capital. The ruffian muttered to himself, as if to motivate Leo.

"Big brother, you will definitely succeed, you will definitely do it, definitely. ”

On the side, Xiaohu's eyes were a little moist, but they were full of firmness.

"Idiot, what are you crying about, get out of the way, get in the way of your grandfather Long's eyes here. Seeing Xiaohu like this, the ruffian dragon reprimanded.

However, the ruffian dragon's voice was as loud as before, but at this time it had an inexplicable tone.

Xiaohu heard the ruffian dragon's reprimand, but he was not as afraid as usual, pursed the tiger's mouth, and muttered: "Still talking about me, what is it in your eyes?"

"You stupid tiger, you dare to talk back?" the ruffian dragon glared at Xiaohu fiercely, threatening.

Xiaohu immediately shrunk his neck and didn't say anything more, but he knew in his heart that the ruffian dragon was just as Leo told him, with a knife mouth and a tofu heart.

"Ah......h

When the ruffian dragon reprimanded Xiaohu, Leo, who was changing his pulse on the ground, screamed again.

Hearing this, the ruffian dragon and the little tiger looked in the direction of Leo in unison.

They saw that Leo's face, although still full of pain, was not as obvious as before.

"Succeeded?" the ruffian was stunned for a moment, a little uncertain.

Xiaohu also stared at Leo's face, feeling uneasy.

At this time, the blood stains on Leo's body began to coagulate, and it was not long before a thick layer of blood shackles formed on Leo's body.

At the same time, the green light on Leo's body bloomed, and the green light spread over the latter's body, and then firmly enveloped Leo's shattered body.

"It's ...... Spirit Vein Protector?" The ruffian dragon's eyes shrank and muttered to himself.

"Big brother succeeded?" Xiaohu roared excitedly.

At this time, on the top of the mountain, the cold wind was blowing, and the ruffian dragon and Xiaohu could also feel it, and the cold wind seemed to have become a little warmer.
