Mu Hanyan thought there would be many obstacles ahead, and wanted to wait until the previous problems were solved before slowly thinking about this one, but she didn't expect that it would arrive so soon.

Logically speaking, the energy was surging at this time, and her subsequent skills were not perfect enough, which might cause the energy to lose control and run around everywhere, causing her to be seriously injured. However, at this moment, the energy suddenly stopped, as if waiting for her to make a decision.

It seems that her guess was correct. Her Tianxin technique can not only absorb the power of all things for its own use, but also accommodate thousands of other techniques. After confirming her guess, Mu Hanyan was naturally ecstatic.

It took a long time for Mu Hanyan to calm down from the huge surprise.

Although she had no worries at all thanks to the magical effects of the Tianxin technique, how to perform the technique next was still a problem.

Just as Mu Hanyan was hesitating, the stagnant energy suddenly rushed forward uncontrollably.

"Could I have guessed wrong? The Tianxin technique isn't that magical after all!" Mu Hanyan was horrified. She knew the consequences of losing control of her Qi: either her meridians would rupture and she would be seriously injured on the spot, or she would explode and die without a complete body. Either way, she was unwilling to accept neither.

Mu Hanyan quickly used all her strength to practice her skills, trying to control the energy, but she was unable to do so.

Mu Hanyan focused her mind and looked inward, watching the powerful energy rush forward like a flood.

"Buzz..." A roar came from my mind, like a pleasant fairy sound.

Looking at her intact meridians, Mu Hanyan was stunned again.

That energy actually passed directly between the two meridians, and a brand new meridian appeared in her sight.

"Hidden meridian!" It actually opened up the hidden meridian.

Mu Hanyan was so surprised that she was almost stunned.

Hidden Veins, according to legend, are invisible meridians within the human body, accessible only to those who have reached a supreme level of cultivation. Opening them up would profoundly transform one's potential, allowing one to reach new heights, perhaps even surpassing human limits and reaching unimaginable realms.

This kind of legend was heard by Mu Hanyan from a hidden master when she reached the realm of Sword Saint in her previous life. However, legends are just legends after all, and the man did not explain it in detail. Mu Hanyan only understood half of it and had no idea what the supreme realm he was talking about was, nor what the so-called unimaginable realm was.

At that level of cultivation, she couldn't even detect the existence of hidden veins. Mu Hanyan even thought it was just a legend, a wishful thinking dreamed up in despair by peerless masters who had reached a bottleneck and could no longer make further progress.

It was not until this moment, when an unprecedented meridian appeared in her body, that she realized that the legend was true.

Having broken through this hidden meridian, the combined Tianxin technique no longer faced any obstacles, and even if there were, they were easily overcome. The internal energy was flowing at a speed at least ten times faster than before, and in just half a quarter of an hour, it had completed a small circulation.

Although it is not very smooth yet, there is definitely no problem with the technique itself.

Surprises came one after another. Even Mu Hanyan, who was much more mature than her peers, couldn't help but feel overwhelmed. It took a long time for her to return to normal.

Practicing the new Tianxin Gongfa, Mu Hanyan once again extended her vital energy towards the Tianxing power deep in her heart meridian.

"Boom" there was another loud noise, and Mu Hanyan's whole body shook violently again, but this time she did not vomit blood, and she felt obviously much more relaxed than before.

If she vomits blood again, she will have to consider eating pork legs to replenish her energy!
