At night, Li Yi sat cross-legged, sweat soaking all the clothes on his body.

In the cultivation process, in addition to the further increase in the strength of the body, with the tempering of the bone marrow, the recovery ability of its martial artist can also be greatly enhanced.

On the ordinary sword, it takes about half a month for ordinary people to recover, but it can be put on the powerhouse of the Refining Realm, but it only takes a day or two to heal as before.

However, the bone marrow is hidden deep in the bones of the human body, and it affects the whole body, and the pain of its tempering can be imagined.

According to Li Yi's scrutiny, the pain he felt when he was in the marrow refining realm had intensified to the point that even Li Yi couldn't bear it.

This also made Li Yi secretly guess in his heart, what level was the level of this exercise called "Pity Flower Treasure Jian" that he cultivated?

All martial artists know that the higher the level of the exercises, the greater the gains brought by their cultivation, but there are also advantages and disadvantages, and the pain that martial artists who cultivate high-level exercises will endure far more than those who practice low-level exercises when they are in the body refining realm and the marrow refining realm.

Moreover, this kind of pain will not subside in a day or two, as long as you are still in the Quenching Body Realm and the Refining Essence Realm, if you cultivate for a quarter of an hour, you will experience severe pain for a quarter of an hour, which is also a difficult place for many people.

Therefore, except for those few who are resolute, a large part of the martial artists, in order to avoid experiencing the unbearable pain, turn to the lowest-level exercises first, and when they reach the realm of fading and the single true qi in their bodies, they exchange for high-level exercises and re-use the true temperature and yang to refine the body and bone marrow.

The strength of the "Treasure of Mercy Flowers" that he is cultivating now is not small, and Li Shimin also said that this exercise was obtained by Lin Shiyin by accident, and the grade is not under the "Shocking Dragon Formula" of the Tang royal family.

This means that the "Treasure of Mercy Flowers" that is being cultivated now is very likely to belong to the lower grade of the prefecture level, or to a higher level.

Not only that, when Li Yi was cultivating, if he was usually running the exercises and cultivating, although the pain would be very strong, he could still accept it, but when he cultivated when Qingmang appeared on this night, the pain would instantly increase tenfold.

The pain had almost reached the point of Ling Chi, and it was as if there were thousands of bone-scraping knives on the whole body and even inside the body.

From this, Li Yi deduced that these green mangs in his body could not only enhance the progress of his cultivation, but also enhance the strength of his tempering.

However, Li Yi knows in his heart that there is no free lunch in the world, and a gain requires a pay, as long as he can enhance his strength, even if the pain is a little stronger, what can he do?

It is also the persistence in Li Yi's heart, whose strength is far superior to others in the same realm.

Therefore, even if every time he cultivated, he wanted to be abused, but Li Yi still insisted on it.

Just when the green light in his body was about to dissipate this time, a wave came out of Li Yi's body, blowing the candle flame on one side and almost extinguishing it.

After the pain in his body disappeared, Li Yifang opened his eyes and exhaled a breath.

At the night before, because of Lu Xiaofeng's curiosity, he opened the glazed white jade box containing the heavenly spirit chalcedony, and at that time, Li Yi suddenly felt that the bottleneck that had been broken through was suddenly relieved.

Although it was only a moment, Li Yi still captured it.

And tonight, Li Yi's strength also officially broke through, entering the fourth layer of the Refining Realm, from the primary stage of the Refining Realm to the middle stage of the Refining Realm.

While cultivating, Li Yi could clearly feel that the progress of today's cultivation was much faster than in the past, and the breakthrough that might have taken three or four days to make a breakthrough had been advanced to tonight.

This situation made Li Yi feel slightly stunned, and he couldn't help but take out the heavenly spirit chalcedony in the storage ring.

Li Yi once tested his qualifications, but in fact, he was only a middle-class qualification, not as good as those gifted cultivation geniuses, and the reason why he was able to increase his strength so much in a short period of time was entirely because of his cultivation exercises and Qingmang.

Cultivation, although the further you go, the higher the requirements for understanding, but the qualifications cannot be ignored either.

What comprehension is aimed at is on the cultivation of martial arts and other skills, while qualification is applied to one's own cultivation.

Outstanding comprehension, in the martial arts cultivation to be stronger, the strength will be stronger, and even be able to achieve leapfrog battles, but even if the leapfrog battles are inevitably limited, if the original defeated enemy, its cultivation will improve rapidly, far exceeding, no matter how good your martial arts cultivation is, it will be in vain.

So, again, the question comes back to qualifications.

The relationship between the two is like that between a fish and water, complementing each other but indispensable.

Li Yi may have known it in his heart before, but he didn't care about it all the time, but today's incident also made Li Yi suddenly think of this problem.

Although the battle is over and the result is as expected, Li Shimin's confession also gave Li Yi a new enemy.

Taoism, a behemoth whose strength and power are better than those of the Tang Dynasty.

Although he continued to cultivate, Li Yi believed that with Qingmang's help, his future achievements would definitely not be low, but Li Yi had a sense of urgency in his heart.

Lin Shiyin's death is inseparable from Taoism, and he was disabled for 17 years because of Taoism, and the hatred in this is not small.

But there is nothing that can be done about a strong person like Li Shimin, who has stepped into the innate more than 20 years ago, let alone his current self.

Thinking of this, Li Yi couldn't help but sigh heavily, "Hey! The strength is insufficient, after all, he can only let the mermaid meat, even if he even lets his mother enter the royal family tree, it happens that this Taoist has something to ask for." ”

Immediately, without thinking about it again, he opened the glass white jade box.

As the box opened, an intoxicating fragrance wafted out of the box, filling the room with this fragrant smell.

Although Heavenly Spirit Chalcedony is a liquid, it is different from ordinary liquid items, and it may be more like a gelatinous substance.

The right hand reached into the box, pinched a corner, and started to be silky and icy, and the entire Tianling chalcedony added up to only two inches in size.

As the Heavenly Spirit Chalcedony entered his mouth, it suddenly melted like water and automatically flowed into Li Yi's abdomen.

Suddenly, a cold and refreshing feeling came from the abdomen, and just as this refreshing feeling flowed through the whole body, it suddenly turned into a scorching heat.

At this time, Li Yi seemed to be in the furnace, scorched by the raging flames, which was a feeling of severe pain that wanted to be cracked.

Under this feeling, the pain from the previous cultivation seemed insignificant.

Li Yi's face was also pale at this moment, and his whole body trembled violently, but under such pain, Li Yi gritted his teeth and didn't want to exhale in pain.

Li Yi didn't leave tonight, but lived in the Rouge Pavilion, and if he exhaled in pain, it would inevitably alarm Lu Xiaofeng and Hua Manlou in the room next to him.

Perhaps because it was too painful, Li Yi's eyes were full of bloodshot at this time, and the green tendons on his neck and hands were bulging, which was extremely obvious.

And in this pain, some bloodlines also began to overflow from Li Yi's body surface, but these bloodlines were different from the normal bright red, but a little mottled, if you can get closer, you can still see some black dirt in these bloodshots.

The effect of Tianling chalcedony is constantly exerted, and the pain is also continuing, and under its medicinal effect, the blood on Li Yi's body is getting bigger and bigger.

Li Yi had forgotten a problem before, in the period of Quenching the Body and Refining the Marrow Realm, when the body had just broken through, the body would fall into a short period of exhaustion because of the breakthrough, because the body was constantly tempered because of the previous cultivation, like a straightened elastic band.

Under normal circumstances, it only takes an hour or two to recover on its own.

But now Li Yi is directly taking Heavenly Spirit Chalcedony, to a certain extent, it is equivalent to another kind of quenching, and even the intensity of quenching is deeper and more comprehensive than when he is cultivating.

When a straightened elastic band is further straightened by the distance again, the consequence is that the elastic band is completely broken.

At this time, Li Yi's situation was the same, the second large-scale tempering, even if Li Yi's physical strength far exceeded that of his peers, it was difficult to bear, and the meridians in his body began to crack because they couldn't bear it.

And Li Yi finally couldn't bear it because of the further aggravation of the pain in his body and passed out.

The cracks in the meridians are getting bigger and bigger, and some of them are already starting to break, and the blood that overflows from the surface of the body is gradually increasing.

The situation is getting worse and worse, and it has reached the most critical time, if the meridians continue to be damaged, the last person who faces Li Yi may be disabled for life and unable to move.
