As always, Yang Chen chose to practice in retreat. Gao Yue got the inheritance jade slip of the cave master, studied tirelessly, and at the same time was refining his dragon horn flying sword, and did not retreat with Yang Chen.

Gongsun Ling still has to go out to practice, and she now has three more Yuanying masters to refine the geographical map of mountains and rivers for her, so naturally the more complete the geography of mountains and rivers, the better. At least all the territory of the Daomen must be visited, and if possible, they will go to sea and go around the territory of overseas cultivation.

There are sharp sword formations and maze formations, coupled with the high speed of the building ship, not to mention the mantis puppet, for the time being, Gongsun Ling's safety does not need to be too worried. Unless someone is targeting Yang Chen, but even the stupidest fool knows that moving Gongsun Ling is equivalent to completely offending Yang Chen, Yang Chen's words, I don't know how many Mahayana masters in Lu Dao are willing to use some people's heads to do favors.

Yang Chen was in retreat alone on a spiritual vein in the cave. He has now cultivated to the sixth picture, and it is estimated that after all the exercises of the eight pictures have been practiced, the second layer of the Dragon Pagoda can be opened to practice more advanced exercises.

Now the size of the roaring sky seems to be slightly larger, and the dragon qi is getting stronger and stronger. All the flying swords in Yang Chen's hands had been digested once in the abdomen by Roaring Heaven, and they were clean, without any sword spirits.

Perhaps after the second layer of the Dragon Tower was opened, Yang Chen could try to ask Roaring Heaven to collect the dragon ball in the Dragon Palace Treasure Vault, which was the real Dragon Palace Treasure Essence.

It is said that it is a retreat practice, but in fact, Yang Chen wants to refine his own Great Yin and Yang Five Elements Flying Sword. The discovery of Ding Huo Zhenyuan made Yang Chen very happy, and some of the fire attribute materials found in the cave mansion were the best for refining Ding Huo attribute flying swords.

Yang Chen took out all these materials as a matter of course, this will be the Ding Huo Flying Sword among Yang Chen's Great Yin and Yang Five Elements Flying Sword.

The jade slips left by the owner of the cave mansion, Yang Chen had already read and memorized them all on the way back. There are some things that are worth learning from Yang Chen.

Before refining the sword embryo, Yang Chen still chose to absorb and fuse all those fire greeting gifts below the third grade into the Yin and Yang Burning Sky Fire.

With the absorption of enough third-grade fires, the speed of absorbing and fusing the first-grade and second-grade fires is now very fast, and one can be completed in a few days, and it only took Yang Chen two years to remove the hundreds of flames after repetition. And as the more fire is absorbed, the Yin and Yang Burning Sky Fire is evolving more and more in the direction of perfection.

The powerful Yin and Yang Burning Sky Fire, fusing these materials to form a sword embryo, and laying Yang Chen's brand, this process Yang Chen completed with ease, and it was many times easier than when he was refining the Jiamu Yimu Flying Sword back then.

It only took two short years for a very exquisite-looking Ding Huo Flying Sword sword embryo to be freshly baked. The perfect Ding Huo attribute, coupled with the materials carefully selected by Taitianmen, made this perfect flying sword sword embryo.

The reason why it is still a sword embryo is because the flying sword has not been tempered by Yang Chen for a long time, and a series of follow-up work has not yet been completed, but it can now be used for battle. If bitten in the mouth of the Roaring Sky, the Ding Huo Flying Sword can also cut off any opponent.

It was rare to calm down and retreat for a long time, and Yang Chen simply did not leave the retreat, but began to carefully study and practice the experience left in the medicine gourd.

Yang Chen, who had already collected enough ordinary medicinal materials, tried all kinds of medicinal materials one by one, all kinds of heat, all kinds of fusions, all kinds of techniques, with his distracted and multi-purpose efforts, with the Yunling furnace, in just ten years, the jade slips in the medicine gourd were carefully studied, and even the combination of a single species and two or three kinds of medicinal materials was also tested once.

In the grid of the medicine gourd, there are tens of thousands of more kinds of medicine residues. This is the residue of the most basic medicine that Yang Chen has personally refined, and it is also the result of Yang Chen's re-consolidation of the most basic knowledge of alchemy in this life. At this point, Yang Chen's shortest board in alchemy has been filled, and he no longer relies on the experience of his previous life. ...,

With these solid basic knowledge, when Yang Chen tried to refine the Second Turning Neicha Dan again, he felt the kind of comfort that was even more handy. Everything was under control, any changes that occurred in the Yunling Furnace were within his expectations, and even which elixir Yang Chen wanted was of high quality and which pill was of low quality, he could easily control it.

This kind of change, compared to Yang Chen's previous refining pills by simply relying on the cognition of the fire, I don't know how many times more advanced the Dao Dao. This is the realm of the alchemist that Yang Chen wants, instead of relying on the old book of the previous life to mix with the senior alchemist, when the old book of the previous life is always used up, now is the time to completely become a real alchemist.

The quality of the second-turn Neichadan that was refined was even higher, which was amazing. Yang Chen even had a feeling that if he started refining the Second Turn Heart Pill now, he would definitely be even more perfect. Of course, the Second Turn Questioning Pill will also be promoted to the third turn under the effect of the Yunling Furnace.

Three turns to ask the heart pill, if it is spread out, it will definitely make people crazy. This grade of elixir, if you take out any one, it is worth getting it with a lot of money. Now, Yang Chen really relied on his alchemy strength to stand at the peak of alchemy in the mortal world.

After more than ten years of retreat, Yang Chen's spiritual power has completely improved to the level of the middle stage of Jindan. If it weren't for the decades spent on the all-attribute condensing pill before, maybe he would have reached this realm long ago.

However, now that the all-attribute spiritual power condensation pill is faster, Yang Chen has a hunch that even if there is no external force, just by relying on his own cultivation, he will be able to enter the late stage of the Jindan after thirty years, and then there will be another hundred years, which is enough to reach the situation of turning into a baby.

Now Yang Chen also has to think about the matter of turning into a baby in advance, the all-attribute spiritual power condensation pill requires at least six kinds of spiritual power condensation pills and three kinds of spiritual power condensation pills of the positive and negative five elements to be able to do it, if it is a baby, it must require more harsh conditions.

It's just that even Yang Chen didn't know what kind of concept the all-attribute spiritual power incarnation was, and what would happen. Although the Yin and Yang Five Elements Technique is powerful, after all, it is only a legendary perfect exercise, and no one has ever practiced successfully before Yang Chen, Yang Chen himself is the pioneer of the furnace.

What will happen, only Yang Chen himself groped, everything is still unknown. However, one thing is completely certain, that is, once Yang Chen's all-attribute infant transformation is successful, then Yang Chen will definitely be the first person in the Yuanying realm, even if he is a master at the peak of Yuanying, he may not be able to compete with Yang Chen.
