Gu must be of great use to this pool of heart protecting liquid.

    He wants to use these heart protecting treasure liquid to impact the yuan pulse in the three hidden veins.

    The three hidden veins are the three strange veins outside the human body. If each hidden pulse can be broken away, it will bring unprecedented benefits to the friars.

    But relatively speaking, the risks brought by the impact on these three hidden veins are also enormous.

    Because of the adverse impact method, if there is a little inappropriate, it will immediately turn itself into a fool.

    However, now that Gu Zhun has so much heart protecting liquid as the bottom, he doesn''t have to worry about this problem at all.

    Because there is heart protecting liquid, as long as the heart protecting liquid in this pool is not consumed, no matter what Gu Zhun makes himself, a drop of treasure liquid will instantly return to its original state.

    This is the amazing effect of heart protecting lotion.

    Thinking of this, Gu Zhun no longer wasted time. His five hearts turned to the sky and began to urge the operation of the golden wing Dapeng formula in his body.

    However, this time, after he had been running for a week, Gu Zhun took a drop of heart protecting treasure liquid from the big pool in front of him, put it in his mouth, and then ran backwards to start the skill.

    After a short time, the skill was reversed, and a lot of blood and spiritual power flowed back in an instant. Suddenly, Gu Zhun felt that a huge blood rushed into his mind.

    The huge pain filled the blood vessels around him, and an unspeakable pain began to diffuse in his viscera.

    "Cough, cough, cough!"

    The pain caused by this severe backflow of Qi and blood is different from that of ordinary people''s handstand. The pain of the former is tens of thousands of times and tens of millions of times that of the latter.

    Even Gu Zhun''s endurance, at this time, he couldn''t help coughing.

    It can be imagined that today''s Gu Zhun has endured what a powerful pain on his body.

    Looking at Gu Zhun''s movement, at this time, the old turtle guarding the door of the grottoes couldn''t help but be frightened.

    Because at this time, Gu Zhun''s body has completely turned red and purple, and there are cracks like cracks on his skin.

    It''s like a long dry land, which makes the old turtle startled even if he only looks at it.

    Young master, what the hell are you doing?

    It''s like playing with your life!

    The old turtle couldn''t understand. Even if he didn''t experience it personally, he felt incomparable pain just looking at it.

    So, after a while, the old turtle didn''t even dare to look. He turned his head directly and let Gu Zhun toss.

    At this time, Gu Zhun''s endurance almost reached the limit of ordinary people.

    However, Gu Zhun still sat there, trembling.

    all but!

    Almost!

    It''s so close that I can touch the hidden pulse!

    Because at this time, Gu Zhun can already feel the existence of the yuan pulse in the three hidden veins.

    Finally, at the last moment, Gu Zhun''s body was about to explode. Suddenly, there was a roar above his head!

    A emerald light emerged. The emerald light showed a thread shape, running through the whole spine from his back neck.

    This is the yuan pulse in the three hidden veins!

    Gu Zhun felt that the yuan pulse was forced out by him. At this time, a trace of ecstasy finally appeared on his face.

    However, just before Gu Zhun was happy, almost at the same time, another unprecedented sense of pain almost tore his whole person in half, his huge blood and brain.

    At the same time, Gu Zhun was also shocked.

    No!

    It''s not good!

    Although his body has practiced the golden winged Dapeng formula, his body still can''t withstand such a huge blood gas impact by reversing the skill.

    Just when Gu Zhun felt that his internal organs were about to explode, he also tilted his neck and swallowed the heart protecting liquid he had prepared earlier.

    A drop of heart protecting liquid will immediately volatilize the powerful and unmatched domineering medicine.

    Almost for a moment, Gu Zhun''s body was protected without omission. At this time, the blood gas that could not be controlled previously was also forcibly suppressed.

    Seeing this, Gu Zhun was finally relieved.

    It''s just that close!

    It''s a pity.

    If you had just given him a little more time, even if it was just a few breath, Gu Zhun could be sure that he would be able to break through that pulse.

    However, unfortunately, their physical strength is not enough.

    A drop of a penny is a thousand miles away!

    Now I have swallowed the heart protecting treasure liquid, and the blood gas around me has been suppressed. The yuan pulse that has just been forced out has naturally disappeared again.

    Therefore, at this time, Gu Zhun can only start again.

    Shook his head, Gu Zhun also gave a wry smile.

    The impact on the three hidden veins is really not done by ordinary people. The strong pain of blood gas flowing back to the brain is enough to make people faint.

    And they should not only keep awake, but also try their best to rush the pulse.

    Moreover, what''s worse, this kind of impact hidden pulse can''t succeed at once.

    The best case is to impact a thousand times. If you are lucky, you can rush away in one fell swoop.

    If you have bad luck, you may not be able to rush away 10000 times, tens of thousands of times, or even hundreds of thousands of times.

    This depends on luck. Therefore, Gu Zhun didn''t look annoyed when he failed to impact the yuan pulse for the first time. Instead, he kept an ordinary heart and took a simple rest. Gu Zhun began his second impact.

    The impact of the three hidden veins tested not only the chance of monks, but also luck, endurance and extremely powerful Taoist heart.

    Without one of the three, it is impossible to complete them.

    To find a person who meets these three conditions in these nine circles, it is almost impossible to find a second person other than Gu Zhun.

    Over the ages, how many monks have risen and fallen in the nine realms, and how many people can struggle for a goal for tens of thousands of years, tens of millions of years?

    Looking at the past and present, looking at the future, except for the owner of the body, there is only Gu Zhun.

    Therefore, at this time, if we can find a person who can break through the three hidden veins in the world, it must be Gu Zhun.

    Therefore, in this small world of Steles and hidden valley grottoes, a long-distance run to impact the yuan pulse also started from this moment.

    Outside the grottoes, if someone is here, you can hardly hear the muffled hum from the grottoes all the time.

    This situation lasted one year, two years, three years

    It didn''t subside until a few years later.
