Chu Tianxiao was a little 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 Stele. Now because the situation was critical, he put all his strength into it. The Heaven-Sacrificing Thunder Art was running frantically, and he finally broke through that threshold by chance!
Of course, this is mostly due to the magic of the Panlong Pillar, which makes his practice more effective!
With a thought, Chu Tianxiao threw the Thunder Spirit into the air with a finger, and then countless arcs of electricity covered the entire place from top to bottom. With a low shout from Chu Tianxiao, violent lightning struck down!
"Thunder breaks!"
With a loud bang, thick electric arcs spun rapidly, cutting, and then fell on the heads of the group of Tongxuan realm powerhouses. Chu Tianxiao was in the thunder and lightning, but was unharmed. He looked at this group of people playfully like Thor, who was electrocuted and felt numb all over, his hands and feet trembling, and then fell down one after another with a thud.
"Having reached the second level of the Heavenly Sacrifice Thunder Art, the power has indeed reached a new level... Even the Tongxuan Realm experts who have undergone marrow cleansing can't withstand it..."
At this time, there were still one or two people who had completed the perfect marrow cleansing and were in the lower realm of Tongxuan left in the field, but for Chu Tianxiao, this was no longer a difficult task. He unfolded the Thousand Moons Phantom Escape, the power of the stars and the moon merged, and the blood-colored moonlight and starlight sword energy were cut down at the same time, completely defeating them in one fell swoop!
whoosh whoosh whoosh!
Several streams of green smoke flowed into Chu Tianxiao's body again. As expected, this spiritual energy of heaven and earth was much more abundant than before, and it was much harder to absorb. Chu Tianxiao hurriedly sat cross-legged in meditation. After a while, a stronger wave of true energy emerged from his body...
Advance to... 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 is done. Even with Chu Tianxiao’s temperament, he was very happy at the moment… Well, the next step is to concentrate on collecting the nine items for marrow cleansing and wait for Tongxuan.
At this moment, more than a dozen Tongxuan lower realm masters appeared in front of him. This time they were a little older and had more combat experience. And once they fought, Chu Tianxiao discovered that each of them was a Tongxuan lower realm master with perfect marrow cleansing!
If such a group of people were placed before Chu Tianxiao's advancement to the Mingyuan upper realm, their physical bodies would be really difficult to defeat. But now that Chu Tianxiao has successfully advanced, the true energy that can be mobilized 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 advance because of the foundation, but on the other hand, once Chu Tianxiao advances to even a small realm, it will greatly improve his overall strength.
"Moonlight Blood Sky Sword!"
"Stars shake the universe!"
"Thunder breaks!"
Chu Tianxiao was not at all weak. He had a strong momentum and used one move after another to defeat this group of people in the lower Tongxuan realm!
If the spectators before had seen this scene, they would have once again lamented that Chu Tianxiao was a beast. However, at this moment, in front of Chu Tianxiao who was in the Mingyuan upper realm, this group of Tongxuan lower realm people... really were not good enough!
“Come again!”
Chu Tianxiao's eyes seemed to be burning with war. The power of thunder and lightning wrapped around his left hand, and he held the Star-Moon Sword in his right hand, attacking from both sides. For a moment, starlight, moon shadows, sword energy, purple arcs... all these brilliances overlapped together, and it looked very gorgeous from a distance, but it was not easy for the group of Tongxuan realm masters who were in it...
Plop, plop!
Even if it was a perfect marrow cleansing, it couldn't withstand Chu Tianxiao's "true energy is free" bombardment. Soon, 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 obtained more spiritual energy from heaven and earth than before, which made his cultivation level in the upper realm of Mingyuan more solid...
Bang!
With just a heavy sound, the last Tongxuan realm expert was pierced through the heart by the thunder spirit. The Star-Moon Sword took the opportunity to pierce his charred wound, and with one move, it completely shattered his heart and lungs!
“Hu…Hu…”
Facing the siege of seventeen Tongxuan realm masters who had undergone perfect marrow cleansing at the same time, even if Chu Tianxiao defeated them, the mental and physical exhaustion was still unavoidable. 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 is necessary to pass all the levels before leaving. How difficult it would be...
"Um?"
When Chu Tianxiao thought of this, his eyes suddenly focused, and he saw another person coming out of the tunnel entrance...
Yes, there is only one person, his cultivation is... the middle level of Tongxuan, judging by his appearance, he is wearing green clothes and has a bald head, and he looks to be around 20 years old...
"That's not right... Even if I'm at the middle level of Tongxuan with perfect marrow cleansing, I shouldn't be able to compare to before... Judging from what happened just now, this test should be getting harder and harder... There must be something fishy going on!"
Chu Tianxiao's mind moved, and then a lightning spirit acted as a pioneer, transforming into a purple dragon, opening its bloody mouth, and the surrounding arcs of electricity rushed madly towards the body of the man in green!
However…
Those electric arcs could only fall on the surface of the man in green. Although he tried desperately to rush in, he couldn't penetrate at all!
Chu Tianxiao's eyes fixed upon seeing this, and the Thunder Spirit soared into the sky. Thick arcs of electricity fell madly, turning everywhere into a purgatory of thunder and lightning, with layer after layer of thunder and lightning power exploding!
However, after the lightning flashed, the man in green only had 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 just eliminated at least three Tongxuan realm strongmen who had undergone perfect marrow cleansing!
Even though he couldn't unleash its full power because he had just comprehended the second level of Heavenly Sacrifice Thunder Art, his physical body was too exaggerated.
"This is… "
Chu Tianxiao looked at the man and suddenly thought of something.
"Extreme Marrow Cleansing?"
When he thought of this, his eyes narrowed slightly...
In fact, even Chu Tianxiao had only seen the words "Extreme Marrow Washing" in the ancient body refining secrets. Because of the interruption of inheritance, few people now know the true meaning of these four words...
As we all know, if you want to increase the strength of your physical body, there are only two systematic ways - 'one-time marrow cleansing' and 'body refining technique'.
The former is the most popular method of strengthening the body in Shenzhou, which can be done in one step, while the latter generally requires multiple steps to train the body... Of course, the ancient body refining technique that Chu Tianxiao is currently practicing is a combination of the two, which can cleanse the marrow multiple times.
The "one-time marrow cleansing" of Shenzhou Haotu includes three methods: general marrow cleansing, perfect marrow cleansing, and extreme marrow cleansing. The last one has been lost. Although the things used in it are still the "nine marrow cleansing materials", the absorption and age requirements are different from the previous two, and the effect will be much better than the "perfect marrow cleansing".
If Chu Tianxiao had mastered the ancient body-refining technique, he would not have taken this extreme marrow cleansing seriously. However, at this moment, he could only reach the fifth level of marrow cleansing at best. In this case, it was not as good as this extreme marrow cleansing that could be fully exerted in one go...
"The sharp contradiction between potential value and current combat power..."
Chu Tianxiao sighed deeply. Is the ancient body-refining technique bad? Not really. Practicing this technique, one can wash the marrow multiple times, and the effect of the final product will far exceed all the "one-time marrow washing". But the key point is... It is too difficult to pile up the number of marrow washings with this method! For example, I have almost reached the fifth level of marrow washing now, which I have obtained by working hard and losing a lot of resources...
"This is really cruel, Dad. There is actually a Tongxuan realm expert who has undergone extreme marrow cleansing in this damn place... It's too difficult for me!"
