When Han Cheng entered the cave, he immediately found the source of the spiritual light, which was a square bluestone standing in the corner of the cave.

Although it is a square bluestone, it is neat and tidy, six feet square, upright on all sides, about three feet unearthed, and buried in the ground. The stone body is smooth and smooth all around, **cool, but the stone is warm.

For the sake of safety, Han Cheng did not immediately move the bluestone, but first used a sword to remove the rocks and sediment next to the stone, and after a while, he picked up the stone to the bottom.

With Han Cheng's current cultivation, with both hands, he lifted the bluestone away almost effortlessly, and when he looked down, the yellow essence as thick as a human arm was like countless black pythons, entangled and coiled to make a bunch, and I don't know how many.

Han Cheng folded a piece and tasted it, his mouth was sweet, containing a large amount of pure spiritual power, and the spiritual effect was more than ten times better than what he had eaten before.

With a flick of his index finger, he shot out dozens of pure yuan sword qi, and in three strokes and five divisions of two, he cut off the yellow essence as thick as a human arm, and all of them were received in the package he carried.

These yellow essences have been moistened by the aura overflowing from the bluestone for a long time, and the medicinal effect is very good, it is a pity to abandon them, keep them and taste them slowly, how much can increase their cultivation, take them out at the critical moment and nibble on a few bites, and they can also be used as a qi recovery pill, quickly filling the mana consumed in the dantian, which can be described as a lot of one stone, Han Cheng will naturally not let it go.

After doing this, he stretched out his hand again, and a golden light swirled around the stone, and the surroundings were like a burst of snow and frost. In an instant, the cocoon was peeled off and the jade was grinding, and a third of it was gone.

At first, there was nothing unusual, but I felt that the stone became more and more delicate the further back it went, with golden light shining and jade snow flying.

After a while, a large bluestone six feet square became a stone pillar six feet high. The texture of the whole body is clear and delicate and smooth, pure white and flawless, and the inside is full of color, and there are flashes of green and silver from time to time.

Han Cheng used his divine thoughts again to carefully inspect the body of the stone pillar, only to see that there was cyan color peeking out of the stone in the lower half, which was faintly recognizable, and the estimated size was only between six or seven inches. If there is liquid flowing in the inside, the upper half is faintly silver, which is where the stone core is.

Knowing that what he expected was true, he naturally didn't dare to use his sword qi to cut it down drastically, if he accidentally cut the stone core or left out a little bit of the empty green, there was nowhere to cry.

In order to prevent outsiders from coming in at a critical time to grab food, Han Cheng deliberately laid two protective prohibitions at the entrance of the cave that he learned from the Baiyang Remnant Chapter, not hoping to be able to block the enemy from the outside, as long as it can have the effect of an early warning.

Han Cheng raised his two fingers, and burst out a three-inch-long True Qi Sword from the end of his fingers, the cold light was shining, condensed but not dispersed, and carefully controlled it to cut off the upper half of the bluestone first, move it aside, and then cut it down to the lower half, seeing that it was getting smaller and smaller, it was only eight or nine inches thick, and it was already able to faintly smell a fragrance, and the body and mind were comfortable for a while.

He opened a small opening at the lower end with the air sword, and heard a soft sound of "snort", and a clear spring as thin as a human finger gushed out of it.

Han Cheng knew that this clear spring was the legendary Wanzai empty green, the essence of Taiyi Yuan essence was extremely pure, and when he opened his mouth to inhale, he felt that the entrance was sweet and cool, refreshing.

Unconsciously, all the ten thousand years of empty green have been included in the abdomen, and I suddenly feel that my whole body is extremely refreshed and my mind is ethereal.

Wanzai empty green is a rare kind of wood attribute heaven and earth treasure, the monk can increase the power of a jiazi, has the effect of cultivating the foundation and being reborn.

Almost a drop of the clear spring just now was swallowed by Han Cheng, and as soon as it entered his abdomen, it quickly turned into wisps of silver-cyan light, wandering among the bones and muscles, and the hundreds of bones in his limbs.

Only the sword immortals above Ling Xuan can withstand so much pure and huge Yimu Qi at once, and most of the monks in the Divine Realm can't bear it, as for those swordsmen who have not yet entered the Dao, they don't have to think about it, it must be an explosion and death.

For the sword immortals who have entered the Dao, how much these ten thousand years of empty green can absorb in the end depends on the quality and attributes of the exercises they practice, as well as the bearing capacity of the physical body and dantian.

After waiting for the 10,000-year empty green in the stone pillar to trickle down, Han Cheng immediately sat down cross-legged, ready to concentrate on cultivation, refining all these 10,000-year empty green into mana, turning it into his own use, and increasing his cultivation to the realm.

He meditated and contemplated, and ran the White Yang Heart Method with all his might, and a pure and condensed liquid true yuan as thick as a thumb slowly came out of the dantian, traveling around the whole body along the seventy-two veins.

Under the inner vision of the Yuan Shen, he saw that the hundreds of bones scattered in the limbs, muscles, bones and muscles were empty blue, exuding a faint silver-cyan light, and the speed of the true yuan in the meridians became faster and faster. All of them were absorbed into the past and merged into the surging and majestic True Yuan torrent, and the True Yuan mana in the dantian meridians was constantly growing at a speed visible to the naked eye.

Trained by a large amount of aura, the Yuan Shen is also continuing to grow and condense, and has been able to show part of the human body's veins, attracting each other and embracing each other with the true qi in the dantian.

The Baiyang Heart Method can subdue, absorb, and transform all the spiritual energy of the five elements of heaven and earth into innate true qi without attributes, without worrying about the waste caused by the incompatibility of attributes, and the qi of Yimu cannot be absorbed.

As the true yuan continued to operate in the meridians, more and more silver-cyan Yimu qi was integrated into it, and the total amount of true yuan also continued to increase, and the original dantian and meridians that were still wide gradually became narrower, and even faintly painful.

At this time, there were still a lot of empty greens that had not yet been refined, Han Cheng gritted his teeth and decided to take advantage of this to break through to the middle stage of Ling Xu, he silently used the Baiyang Mind Method, hugged Yuan Shouyi, and tried his best to refine those silver and cyan rays, and at the same time distracted his thoughts, and guided the rest of the mana to refine the dantian and meridians with his divine thoughts, enhancing their toughness and strength, so that they could accommodate more aura.

After being tempered and strengthened, the dantian and meridians were much larger and wider than the original, and it took Han Cheng dozens of days to refine all those ten thousand years of empty green that flowed into the hundred bones of his limbs, and the mana of his whole body more than doubled, and he successfully broke through to the middle stage of Ling Xu.

After the Yuan Shen received sufficient spiritual energy training, it became more and more condensed, and it was able to initially withstand the chaos of the material world, and it was out of the body, but it could only be out of the body for a while, the time could not be too long, and there were many restrictions, without the protection of the physical body, in general, it was still relatively fragile.
