After Xingqiu left, Su Chen waited for another half an hour, and after making sure that it was safe, he got up and opened the mechanism and walked out of the underground secret room.

With a step under his feet, he chased the clouds and took steps, and his figure suddenly turned into an afterimage, and the wooden box on the ground was gone.

Back in the room again, Su Chen entered the secret room again, and did a good job of protection, only then did he open the wooden box and take out the glaucoma mirror inside.

The mirror is a bit heavy to start with, but it is not light, and it is obvious that the material made of it is not ordinary bronze, and there are circles of small runes hidden in the flame patterns around the mirror.

It is precisely because of these runes that the bronze mirror has an extraordinary ability to absorb the sun's glow.

This thing is equivalent to an otherworldly version of a solar power bank.

The accumulated solar energy can be used to accelerate the cultivation of pure yang gong, and it can also be used as an explosive means.

A very good treasure indeed.

Only those who have cultivated Pure Yang Gong can use Pure Yang True Qi to refine and control it, while those who have not cultivated Pure Yang Gong can only reach the innate realm and forcibly use the Innate Yuan Qi and huge essence blood to soak and achieve the effect of control.

It was precisely for this reason that Xingqiu had to take out this thing to make a bet on the transaction.

"Although I don't have the cultivation of the Innate Realm yet, I have been cultivating Pure Yang Gong for several years, and it should be enough to refine and control this glaucoma mirror."

Between thoughts.

Su Chen put the mirror on the stone table, then took two steps back, and felt unsafe, so he took a stone slab next to him and put it in front of him as a shield, and then raised his hand to shoot out a pure yang true qi.

I saw that the wisp of true qi barely broke through the body and flew out towards the mirror, and was immediately absorbed by it.

The flame inscription on the mirror shone slightly, and the sun's light stored in it bloomed.

Suddenly, the whole secret room was as bright as day.

The sun was bright and scorching, and Su Chen bathed in it, with the illusion that it seemed to be melted.

But it's not uncomfortable.

Under the illumination of the light, the operation of pure yang power in the body seemed to have accelerated a little.

Unfortunately, the light only lasted for a moment before it vanished.

Obviously, with just a little pure yang true qi, it was impossible to truly refine the Qingguang Realm.

However, this attempt also convinced Su Chen that Pure Yang Gong could indeed refine the glaucoma mirror, and he did not find any hidden killing moves and crises in the mirror.

Confirm security.

Then the rest is very simple.

Slowly use pure yang true qi to refine the glaucoma mirror.

Thinking of this, Su Chen no longer hesitated, immediately retrieved the glaucoma mirror, put it in his hands, and then sat down cross-legged and began to run the Pure Yang Gong.

Continuously injecting the pure yang true qi in the body into it, it began to slowly refine.

This glaucoma mirror, after all, is a magic weapon treasure, although the pure yang skill can indeed trigger it, but because Su Chen's current cultivation is not strong enough, the speed of refining is even slower than imagined.

It took him a full seven days, and he only managed to refine a few corners, and he succeeded in lighting up a flame rune around the mirror.

It is still a lot short of complete refining.

Su Chen was not in a hurry, time had polished his patience more and more tenaciously.

In the following days, he worked at sunrise, and after completing the simple work, he took the glaucoma to bathe in the sun, and practiced and refined at the same time.

Of course, the cultivation of Tiangang Tongzigong has not fallen.

Under the tempering of pure yang gong, this exercise is also making rapid progress.

In addition, he would also spend two hours a day to study and cultivate the exercises that Lin Fan had sent before.

Especially the Broken Jade Decision, this technique played a very important role in the process of refining the glaucoma mirror.

Because the pure yang true qi cultivated every day was not enough to maintain the consumption of refining, Su Chen's daily consumption of qi and blood was extremely large.

Food and Zuogui wine alone are completely unable to keep up.

The Broken Jade Decision can obtain a large amount of essence power by burning life potential, which can perfectly make up for the consumption.

In this process, Su Chen also made a slight attempt first.

He found that once the Broken Jade Decision was activated, the life potential in his body would be burned, and the Immortal Dao Seed would automatically absorb a magical power from the heavens and the earth to replenish it.

In this way, there will be no damage to oneself, and there will be no loss of the Dao species.

That kind of power that was ingested, Su Chen didn't know what it was, maybe it was the so-called heaven and earth aura, or a higher level of immortal energy, or something like the origin of the universe.

He doesn't understand it yet.

But as long as he was sure that neither the Dao Seed nor himself would leave hidden dangers due to the burning of his life potential, he would be completely relieved.

Practicing the broken jade decision every day, the skill has grown rapidly.

And insisting on refining the glaucoma mirror every day, the true qi in the body is almost exhausted, and then replenished again, and this process is repeated repeatedly.

A year later.

Su Chen unexpectedly found that his true qi had become much purer, and his strength could really penetrate deep into his bones.

A part of the bone marrow and viscera became crystal clear under the nourishment of true qi, like lead mercury chalcedony.

And the tempering of the viscera and bone marrow has also brought great changes to him.

It's not just an increase in strength and physique.

Su Chen obviously felt that his five senses had become more and more acute, between breathing and breathing, his ears and eyes were smart, and he could clearly grasp any wind and grass in the entire Kwai Garden.

The true qi in the body can gradually emanate from every pore with the breath, and it can already be easily broken out of the body for several feet.

At this point, he can be regarded as truly stepping into the third realm of martial arts, refining the marrow.

It's just the beginning, though.

But he has reached the real sense of both internal and external cultivation, and can be regarded as a first-class master in the world.

Next, it is only necessary to accumulate the power of true qi step by step, and finally accumulate to an extreme, and then you can cause qualitative changes from quantitative changes, and try to break through the legendary innate realm.

And with the unremitting efforts of this year.

The glaucoma mirror was finally completely refined and controlled by him, and he could absorb the sun's light freely, his cultivation speed increased greatly, and the stored power of the sun could maintain normal cultivation as usual at night and on rainy days.

The increase in the glaucoma mirror, coupled with the improvement of the broken jade duel, Su Chen's cultivation speed was even faster.

Originally, it was expected that it would take at least ten years for him to reach the realm of refining the marrow.

But with the help of the Qingguang Realm and the Broken Jade Duel.

It only took Su Chen five years to successfully refine the bone marrow of the whole body.

Tiangang Tongzi Gong and Pure Yang Gong have also been cultivated by him to the point of perfection.

In addition, Su Chen also practiced several other martial arts techniques, enriching his martial arts accumulation and combat methods.

Today, he has a strong physique, pure and masculine internal strength, and his accumulation is extremely strong, plus he also cultivates the martial arts techniques of various factions.

With such strength, looking at the rivers and lakes martial arts, it can also be regarded as a first-class top.

Compared with the two sword gods who fought against each other on the Zhengyang Gate, Su Chen also asked himself that he would not be weaker than them.

As long as the innate master does not come out, there is absolutely no problem with self-preservation.

Of course.

After all, there is no real breakthrough yet.

At this realm, Su Chen knew better that the gap between half-step innate and innate was probably even greater than that of blood exchange to marrow refining.

Not to mention that above the innate level, there may also be high-ranking immortal cultivators, so they can't be expanded.

Low-key development is still the survival criterion pursued in the future.

However, the improvement of his strength also gave him more choices, at least he didn't have to be too cautious, and he didn't have to be trapped in the place of Kwai Yuan.

When necessary, he can also leave Kwai Yuan and enter and leave the palace freely to see the outside world of flowers.
