The clouds in the sky were leisurely drifting with the wind, as if they were showing a different kind of smiling face, the wind gently caressed the earth, Qin Shan and Gu Yan had already cleaned up at this time, ready to leave the cave. After all, this place is not far from the goshawk tribe, and there is a high chance of being discovered.

"Young Master, what should I do with the corpse of that giant python?" Could it just be thrown here?" Qin Shan looked at the dead giant python and felt that it was a pity, but it was not good to take it away directly, after all, the giant python was poisonous.

"How can you throw it here, you go and take out his poison sac, Ben Shao will go and see if there are any other treasures. After speaking, Gu Yan threw the iron spirit sword to Qin Shan, and he himself entered the cave where the python dwelled, and the ground was covered with white snake foam, which was very disgusting.

When I approached the cave, the yellow rock wall turned red. Gu Yan was very curious, and gradually, Gu Yan saw the rock wall clearly, and it was actually covered with a small vine. And the little vine was covered with snake foam, but it didn't smell like that at all.

Gu Yan took out his iron spirit dagger and cut off the small vine in a piece. Suddenly, a milky liquid like blood flowed out, and it smelled of blood. Gu Yan suddenly jumped up happily, "Damn, it turned out to be a snake and a red blood vine, the master's luck is too rebellious." ”

Unexpectedly, these small vines were precious mortal-level elixirs - snake smacking red blood vines. This small red vine grows by absorbing snakes, which is a special elixir, which can not only increase the qi and blood energy of warriors, but more importantly, it can be combined with red ginseng and Poria cocos grass to make snake blood spirit ointment.

The snake sucking blood spirit ointment can help the warrior repair the damage, and even break through the realm, and at the same time, it can also enhance the warrior's physique. The value is not at all below a handful of mortal-level intermediate crystals, so Gu Yan is so excited, after this elixir is made into the snake blood spirit ointment, the medicinal effect is enough to help him step from the muscle-building stage to the bone-forging stage.

Soon, Gu Yan began to collect these red blood vines in a big way, and put them all into wooden boxes, and now that he has a storage ring, these things can be easily taken away. In less than half an hour, Gu Yan had already picked all the red blood vines, and the rock walls of the entire cave had returned to that dark yellow.

And Qin Shan had already included the giant python's poison sac in the talisman, and now he was also a person with a storage device. Because Gu Yan had a storage ring, he naturally gave the talisman to Qin Shan.

After finishing their errand, the two men then burned all the bodies on fire and retreated by the other way. Along the way, all the footprints were destroyed, leaving no clues, lest the goshawk tribe come to the door.

At this time, it was already evening, and the two of them were already hundreds of miles away from the cave. At this time, the two of them were spending the night in a cave not far from Gulong Village, and the two could actually return to the tribe in the evening, but Gu Yan dispelled that idea.

Because he wanted to break through to the fourth order of skin refining in the Hui clan first, at that time, with his hole cards, even without the help of his grandfather, it was enough to compete with the two elders. And he is confident that he can break through tonight, you must know that he has three blood beads.

Three blood beads, for other people, even if it breaks through from the skin refining stage to the muscle building stage, it is enough. But for Gu Yan, at most, he could break through to the middle of the fourth order of skin refining, after all, the exercises he cultivated were too advanced, and the energy required for each breakthrough was several times that of ordinary people. Although it may seem like a lot of money, you must know that the benefits in exchange for that are also huge.

An ordinary third-order martial artist refining skin, even if he uses the strength to eat milk, the strength to be able to punch eight hundred catties is already very good. But Gu Yan, let alone eight hundred catties, has the strength of thousands of catties in one punch. And this is the difference between low-level and high-level exercises, and the role played by the martial artists themselves is different. Cultivating high-level exercises can not only make the qi and blood energy more refined, but also increase the qi and blood capacity of martial artists of the same level.

After eating the jerky, Gu Yan asked Qin Shan to protect the Dharma for him, and he was going to break through the fourth order of skin refining tonight.

Hearing that Gu Yan wanted to cultivate and break through the fourth order of skin refining, Qin Shan suddenly changed his relaxed state, responded cautiously, and then silently walked to the entrance of the cave, focusing on patrolling the surroundings in case of accidents.

Gu Yan, who was sitting cross-legged, had an open wooden box in front of him, which contained three precious blood beads, but Gu Yan did not hesitate at all, and directly swallowed one blood bead into his stomach. Although the blood beads are precious, they are used to break through the fourth order of the face skin, which is a waste in the eyes of others, but in Gu Yan's opinion, it is not, he believes that only when his strength is strong is the royal way.

"At this time, my qi and blood energy is already at the peak realm of the third order, and with the help of this blood bead containing the qi and blood energy of the desolate beast, it should not be difficult to break through the realm. Gu Yan muttered, and then ran the exercises of the "Yijin Sutra" to refine that pure blood bead.

But he still underestimated the domineering of his body, and the qi and blood energy contained in a blood bead only made his third-order peak realm shake slightly, and there was no sign of breaking through. His body has been transformed by the "Yi Jin Sutra" and is no longer an ordinary physique, and the meridians of his whole body are much thicker than before, so he needs more energy to break through.

"Damn, Ben Shao is out of the way. Immediately afterwards, Gu Yan paused, opened his mouth, and two crystal blood beads rotated in his palm, which instantly seemed to have spirituality, crossed two curved arcs, and then fell lightly into Gu Yan's mouth······

After swallowing the two blood beads again, the third-order peak qi and blood energy entrenched in the dantian and meridians in Gu Yan's body instantly became very violent like a poisonous dragon going out to sea.

It's not surprising who called Gu Yan so bold. The blood bead is a treasure condensed from the blood of the desolate beast, although the qi and blood contained in it are pure, without the fury of the blood of the beast, but the qi and blood energy contained in it is not a small amount.

Ordinary martial artists, although it is not common to dare to swallow it with the third order of skin refining, there are quite a few. But few people who dare to swallow two at a time have really tried it, and the majestic qi and blood energy is enough to burst the meridians and dantian of the martial artist.

Gu Yan forcibly endured the majestic qi and blood energy that was wantonly strung in the meridians, and quickly ran the "Yijin Sutra", and then the exercise route ran rapidly in the body, which was used to suppress and pull that energy.

With the flexible operation of the "Yijin Sutra", the chaotic and majestic energy was slowly absorbed and refined by a trace, and a warm energy rose up, along the meridians in the body, turning around the limbs and hundreds of remains, at the same time, the barrier of the fourth order of the skin refining period also began to loosen little by little. And as that qi and blood energy was gradually absorbed, the pain in Gu Yan's body gradually disappeared.

As time passed slowly, the exercises of the "Yijin Sutra" were operated by Gu Yan for a week, and finally, the corners of Gu Yan's mouth turned up slightly.

"The opportunity has finally arrived. ”

Suddenly, Gu Yan frantically ran the exercises of the "Yijin Sutra", directly converging that qi and blood energy together to form a torrent.

"Broken!"

A divine consciousness cry erupted from the bottom of Gu Yan's heart, and then, with the warm energy generated after refining some blood beads, fused with each other to form a more powerful qi and blood energy, wrapped in a courageous forward, non-looking momentum, turned into a surging river for a day, and rushed head-on towards the last layer of bottleneck barriers.

Under the impact of the torrent of energy full of warmth and riot, the last layer of barrier was simply vulnerable, and it was directly broken down. In an instant, Gu Yan felt extremely refreshed.

In an instant, the Heaven and Earth Yuan Qi from the outside world burst into Gu Yan's body, washing and moisturizing every inch of his skin, and finally Gu Yan felt that his entire body seemed to be strengthening. At the same time, a trace of black smudge seeped out from between the pores of Gu Yan's skin, and this was the effect of this blood bead containing pure energy—washing the meridians and cutting the marrow.

In Gu Yan's understanding, the importance of washing the scriptures and cutting the marrow to the warrior is incomparable. Legend has it that there is an elixir in the world that can help people completely wash the meridians and cut the marrow, change their martial arts qualifications, and from then on, they will get rid of the mortal womb, become holy bones, and become demonic people. But that elixir is so precious and rare, and it is not at all something that ordinary people can have.

However, a martial artist can change his root bones through cultivation to achieve an inner process of washing the meridians and cutting the marrow, but this kind of opportunity is extremely rare, the lower the general realm, the greater the probability of appearing, and Gu Yan's breakthrough this time is a precious process of washing the scriptures and cutting the marrow.

Some super tribes or sects, even if they have a method or elixir that can wash the marrow of their descendants, they will not let them use a single one. Because the external washing of the scriptures and the marrow is not complete, only the inner washing and marrow removal can have the effect of "rebirth".

Feeling the new realm, the fourth-order skin refining not only made the qi and blood energy in Gu Yan's body more refined, but also the qi and blood energy in the body increased a lot. With the operation of the "Yijin Sutra" exercises, these surges of qi and blood energy, like spring wind and rain dew, circulate the limbs and hundreds of remains, moisturizing the five internal organs.

And Gu Yan's strength has improved a lot, and now he feels that a punch has at least more than 1,500 catties of strength, which is enough to kill a medium-sized beast. These books are the strength of the fifth-order masters of muscle building, and coupled with his two basic advanced combat skills, he is confident that he can now compete with the two elders.

Immediately after that, Gu Yan continued to meditate and practice for a while, and ran the three-layer exercises of the "Yijin Sutra" for three weeks in a row, and Gu Yan completely stabilized the realm of the fourth order of skin refining. Subsequently, Gu Yan informed Qin Shan, and practiced martial arts outside the cave and under the moonlight.
