The Prodigal Son of the Mystical Sect

Chu Tianxiao was somewhat surprised. This great emperor-level secret technique was extremely difficult to improve. Fortunately, he had first comprehended it for a long time on the Panlong Tablet. Now, because of the critical situation, he used all his strength and madly operated the Heavenly Thunder Art. Finally, he broke through the threshold by chance!

Of course, this was mostly due to the wonder of the Panlong Pillar, which made his practice more effective!

With a thought, Chu Tianxiao threw the Thunder Spirit into the air with one finger, and then countless arcs of electricity covered the entire venue from top to bottom. With a low shout from Chu Tianxiao, violent lightning struck down!

"Thunder Breaks!"

With a bang, the thick arc of electricity rotated rapidly, cut, and then fell on the heads of the group of Tongxuan Realm masters. Chu Tianxiao was in the thunder and lightning, but he was unharmed. He looked at the group of people who were numbed by the electricity, their hands and feet trembling, and then fell down one after another with a plop.

"Having reached the second level of the Heavenly Sacrifice Thunder Art, the power has indeed reached a new level... Even the Tongxuan realm masters who have undergone marrow washing can't stand it..."

At this time, there were still one or two Tongxuan lower realm masters who had undergone marrow washing perfectly, but for Chu Tianxiao, this was no longer a difficult task. The Thousand Moon Phantom Escape unfolded, the power of the stars and the moon merged, and the blood-colored moonlight and the starlight sword energy fell at the same time, completely defeating them in one fell swoop!

Swoosh, swoosh, swoosh!

Several streams of green smoke poured into Chu Tianxiao's body again. As expected, this spiritual energy of heaven and earth was much more than before, and it was also much more difficult to absorb. Chu Tianxiao hurriedly sat cross-legged in meditation. Not long after, a stronger wave of true essence emerged from his body...

Advancement...Mingyuan upper realm!

"It's really not easy..." Chu Tianxiao nodded with satisfaction. Originally, he needed to practice hard for about half a month, but now it was completed directly. Even with Chu Tianxiao's temperament, he was very happy at this moment...Well, the next step is to collect the nine items for marrow washing and wait for Tongxuan.

At this moment, more than a dozen Tongxuan lower realms appeared in front of him. This time they were slightly older and had more combat experience. Moreover, once they fought, Chu Tianxiao found that each of them was a Tongxuan lower realm with perfect marrow cleansing!

If such a group of people were placed before Chu Tianxiao's promotion to Mingyuan upper realm, their physical bodies would be really difficult to fight, but now that Chu Tianxiao has successfully promoted, the true essence that can be called from the snow mountain qi sea is not only more powerful, but the key is that the "quality" has also been improved a lot - although it is difficult to promote because of the foundation, but on the contrary, once Chu Tianxiao is promoted to even a small realm, it can improve a lot of comprehensive strength.

"Moonlight Blood Sky Sword!"

"Stars Shock the Universe!"

"Thunder Breaks!"

Chu Tianxiao is not at all empty, his momentum is soaring, one move after another, and he actually suppresses this group of Tongxuan lower realms!

If the spectators before saw this scene, they would definitely sigh again that Chu Tianxiao is a beast, but at this moment, in front of Chu Tianxiao in Mingyuan upper realm, this group of Tongxuan lower realms... really, not good enough!

"Come again!"

Chu Tianxiao's eyes seemed to be burning with war. The power of thunder and lightning rolled up his left hand, and the Xingyue Sword was held in his right hand. He attacked from both sides. For a moment, starlight, moon shadow, sword energy, purple arcs... the layers of brilliance overlapped together, and it looked very gorgeous from a distance, but the group of Tongxuan realm masters in it were not easy...

Thump, thump!

Even if it was a perfect marrow cleansing, it couldn't withstand Chu Tianxiao's "true essence is free" bombardment. Not long after, the first person fell, and then more and more people followed, turning into green smoke and rushing into Chu Tianxiao's body.

This time, Chu Tianxiao got more spiritual energy from heaven and earth than before, which made his cultivation realm of Mingyuan Shangjing more consolidated...

Bang!

With a heavy sound, the last Tongxuan realm master was pierced through the heart by the thunder spirit. The Xingyue Sword took the opportunity to pierce his charred wound, and with one move, his heart and lungs were completely crushed!

"Hu...Hu..."

Facing the siege of seventeen Tongxuan realm masters who had perfectly washed their marrow at the same time, even if Chu Tianxiao defeated them, the mental and physical exhaustion was still inevitable. He panted slightly, thinking that it was no wonder that the Panlong Pillar only had three levels of tests. You can leave after passing the first level... Come to think of it, the first level is so difficult, and the subsequent levels will only be more troublesome. The difficulty is abnormal. It takes people to pass all the levels before they can leave. How difficult it is...

"Hmm?"

When Chu Tianxiao thought of this, his eyes suddenly condensed, and he saw the tunnel there. Another person came out from the entrance again...

Yes, only one person, cultivation...Tongxuan middle realm, judging from his appearance, he was bald in green, about twenty years old...

"That's not right...Even if he is in Tongxuan middle realm with perfect marrow cleansing, he should not be able to compare with the previous one...Based on the situation just now, this test should be getting harder and harder...There must be something fishy!"

Chu Tianxiao's mind moved, and then, a touch of thunder spirit acted as a pioneer, turning into a purple dragon, opening its bloody mouth, and the surrounding arcs rushed towards the body of the man in green!

However...

Those arcs could only fall on the surface of the man in green, and although they tried desperately to rush in, they could not penetrate at all!

Seeing this, Chu Tianxiao's eyes condensed, and the thunder spirit soared into the sky, and thick arcs fell madly, turning into a thunder and lightning purgatory everywhere, and layer after layer of thunder and lightning power exploded!

However, after the lightning flashed, the man in green had only countless holes in his clothes, but there were only white marks on his body, and not even a drop of blood flowed out... And this attack had just killed at least three Tongxuan Realm strongmen who had perfectly washed their marrow!

Even though he had just comprehended the second level of the Heavenly Sacrifice Thunder Art and could not exert his full power, the opponent's body... was too exaggerated.

"This is..."

Chu Tianxiao looked at the man and suddenly thought of something.

"Extreme marrow cleansing?"

At this thought, his eyes narrowed slightly...

In fact, even Chu Tianxiao has actually only seen the words 'extreme marrow cleansing' in ancient body-refining secret books. Because of the inheritance and generation, few people today know the true meaning of these four words... …

As we all know, if you want to improve your physical strength, there are only two systematic methods - 'one-time marrow cleansing' and 'body refining'.

The former is the most popular method of strengthening the physical body in the vast land of China. It can be achieved in one step, while the latter generally requires multiple steps to exercise the physical body... Of course, the ancient body refining technique that Chu Tianxiao is currently practicing is two-step. The combination of the two can wash the marrow multiple times.

The "one-time marrow washing" of Shenzhou Haotu includes three methods: general marrow washing, perfect marrow washing, and extreme marrow washing. The last one has been lost. Although the things it uses are still the 'Nine Marrow Cleansing Objects', they are different from the first two in terms of absorption and age requirements, and the effect will be much better than the 'Perfect Marrow Cleansing'.

If Chu Tianxiao had completed his introduction to the ancient body refining technique, he would not take this kind of extreme marrow cleansing seriously, but at this moment, he would be close to the fifth level of marrow cleansing even if he was exhausted. In this case, it would not be as good as this one-time marrow cleansing. Just do your best to cleanse your marrow...

"The sharp contradiction between potential value and current combat power..."

Chu Tianxiao sighed deeply and said, "Isn't the ancient body refining technique good?" No, by practicing this technique, you can wash the marrow multiple times, and the final product will be far more effective than all the 'one-time marrow washes'. But the key problem is... it is too difficult to pile up the marrow washes using this method! Let’s just say that the nearly five levels of marrow cleansing that I have now are all obtained by working hard and losing a lot of resources...

"It's so cruel, Dad, that there is a powerful man from the Tongxuan Realm who can do the ultimate marrow cleansing in this damn place... It's so difficult!"
