In a quiet cave, Lu Feng sat cross-legged and looked at the Thunder Pill in his hand, with thunder flashing on it.

Lu Feng pondered for a moment, gritted his teeth, and swallowed all the three Thunder Marrow Pills.

Now, in the Ten Thousand Beasts Mountain, there are not only ferocious and violent demon beasts, but also Yuan Dan realm masters like Ji Zong, who can be described as surrounded by strong enemies.

Previously, his trick was to lead the water to the east, not only targeting the Black Thorn Lion on Ji Zong and Deng Qing, but also successfully obtained the Thunder Marrow Pill, but once Ji Zong found out that he was fooled, he would definitely be angry and try his best to find himself, so he must improve himself as soon as possible and make a breakthrough again!

When the pill entered his body, it immediately turned into rolling medicinal power, flowing in Lu Feng's limbs, Lu Feng hurriedly gathered his mind and absorbed the energy in the Thunder Marrow Pill.

Su Yumo, who was on the side, saw Lu Feng start refining the Thunder Marrow Pill, walked out lightly, and stayed at the entrance of the cave.

It took time to refine the Thunder Marrow Pill, and what she had to do was to observe the surrounding situation to avoid any demon beasts from breaking in or Ji Zong and Deng Qing finding them and interfering with Lu Feng's cultivation.

At this moment, the sun is setting, and the Ten Thousand Beasts Mountain is gradually shrouded in night, and the sky is dotted with stars.

Su Yumo glanced at Lu Feng, whose eyes were slightly closed, although the young man's body was not strong, but there seemed to be infinite strength in his body, and his handsome face like a sculpture was angular and faint, as if mixed with a sense of vicissitudes.

As if sensing that he was a little distracted, Su Yumo hurriedly glanced away, looked at the endless starry sky, and unconsciously recalled the bits and pieces of the acquaintance between the two.

In the secret space, the silver spear pierced the belt of the bun, the girl's green silk hung down like a waterfall, and the young man took her into his arms, and at that moment, time stood still.

At that time, as a wisp of green silk fell, the girl's heart seemed to be struck, and it became eternal.

Unconsciously, that figure had left a deep imprint in Su Yumo's heart.

Thinking that two days later, the two of them would enter the sect separately, Su Yumo's heart couldn't help but feel a little reluctant.

"Phew, how could I think about this!" Su Yumo hurriedly shook his head and drove these messy thoughts out of his mind, but there was a faint flush on his pretty face.

Su Yumo, who was immersed in complex emotions, didn't notice at all that at this time, Lu Feng's face was full of green tendons, as if he was in great pain, and fine beads of sweat poured out of his forehead.

At this time, in Lu Feng's body, some kind of amazing change was taking place.

It turned out that the moment he swallowed the Thunder Pill pill, the power of the three heavenly thunders contained in the three pills surged out and began to run uncontrollably in his body.

This kind of situation also made Lu Feng's heart sink, if he couldn't control and absorb the power of these three heavenly thunders, he would inevitably suffer a backlash and lose his cultivation.

Heavenly thunder is already a force of nature, if it is replaced by ordinary people, I am afraid that if you touch it, you will die, and how dare you take it into your body.

Lu Feng did this, also relying on the majestic energy in his body, Rao was like this, but he still despised the power of nature.

Absorbing the heavenly thunder into the body is already against the sky, not to mention, he swallowed three thunder pills at the same time, in the eyes of ordinary people, such a practice is tantamount to self-defeat.

At this moment, the power of the chaotic heavenly thunder almost burst Lu Feng's meridians, but Lu Feng did not panic in the slightest, he knew that the more he was at such a time, the more he had to stay calm.

He sealed his hands and mobilized the energy of his whole body to wrap the power of the heavenly thunder, and the power of the heavenly thunder finally stagnated, however, before he could absorb the energy in it, the power of the heavenly thunder was out of his control again, and the power of the three heavenly thunders swam in his body like a thundersnake.

Lu Feng's face changed slightly, he still underestimated the power of this heavenly thunder, if he was allowed to rampage through his body, he might break through the meridians and explode to death.

At this moment, the Yuan Force Seed also seemed to feel the fatal crisis, and the majestic energy roared out, wrapping the power of the Heavenly Thunder, and the restless Three Thunder Snakes gradually calmed down under the suppression of such energy, and began to frantically absorb the power of the Heavenly Thunder.

Seeing this, Lu Feng finally breathed a sigh of relief and began to try to guide this energy to refine the power of the three heavenly thunders.

Time passed in a minute and a second, and the sky, from the stars in the middle of the night to the dawn before it was white.

A night had passed, and Lu Feng was still immersed in refining the Thunder Marrow Pill.

After a night of refining, he had refined all the medicinal power of the two Thunder Marrow Pills, and only the last one of the three Heavenly Thunder Powers remained.

Looking at the last power of the heavenly thunder, Lu Feng groaned slightly, mobilizing all the energy in his body to impact it.

Unexpectedly, the next moment, something happened suddenly.

The last thunder snake, which had already calmed down, actually burst out with a powerful force in an instant, dispersing all the energy in Lu Feng's body, and then dividing it into several sections, impacting towards the meridians in Lu Feng's body.

"Poof!"

The sudden change caught Lu Feng a little off guard, and the violent force caused his internal organs to suffer, and then a mouthful of blood spurted out.

"Lu Feng, what's wrong with you?" Su Yumo, who heard the movement, hurriedly ran over, his pretty face was full of worry.

Lu Feng waved his hand, his hands were sealed again, controlling the energy in his body, and chased towards the heavenly thunder, but the heavenly thunder had been divided into several sections, and Lu Feng couldn't control them all for a while.

"Careless!" Lu Feng scolded secretly.

It turned out that just last night, when the energy in the Yuan Force Seed wrapped the power of the three Heavenly Thunders, two of them actually dispersed most of the energy to the third Heavenly Thunder, which allowed Lu Feng to easily refine the power of the two Heavenly Thunders.

Now, if Lu Feng wants to refine the last one, it will naturally cause a counterattack.

But at this time, it was found that it was already a little too late, and several sections of heavenly thunder were frantically swimming in his body, and Lu Feng wanted to suppress them, but it was useless.

Just when Lu Feng had nothing to do, in his mind, a trace of air flowed out again, pouring straight into Lu Feng's Yuan Force Seed.

Suddenly, an unprecedented huge amount of energy erupted from the Yuan Force Seed, and then this energy was also divided into several paths, flowing out in the direction of the Heavenly Thunder Escape.

Sensing the horror of this energy, the thunder snake seemed to scream, wanting to escape again, but this energy did not give any chance, and directly absorbed all the power of heavenly thunder in Lu Feng's body.

The last of the Heavenly Thunder Power was absorbed and transformed into a more refined medicinal power.

At this time, feeling the changes in his body, Lu Feng frowned slightly, full of doubts, but no matter what, the power of heavenly thunder was absorbed, and the crisis was resolved, and the next step was to refine all the medicinal power in his body.

Lu Feng believes that by that time, his physical strength will definitely reach another level!
