The reason why Ishikawa purchased so many items and returned to the inn was because the box that Cangcunsuo gave to Ishikawa at the end actually contained a third-order demon beast's inner pill, although the spiritual power had been basically exhausted, and it was almost on the verge of collapse, it seemed that a slight external force would make this third-order demon beast inner pill disappear, and even Ishikawa didn't dare to have the divine sense to take a closer look.

The third-order demon beast Inner Dan can only be produced by a third-order demon beast comparable to a Jindan stage monk. In the vicinity of the Southern Liang Kingdoms, even Jindan stage monks are extremely rare, let alone demon beasts in the Jindan stage. Even if one is found occasionally, no one has the strength to kill it and seize the demon pill.

This third-order demon beast inner pill is even more precious. The position of the position in the Spirit Beast Sect is definitely not low.

According to the description in "Qinggang Sword Array", the Dan Crystal that the third-order demon beast Neidan can raise is enough to be worth dozens of second-order demon beast Neidan. In this way, Ishikawa had enough Danjing, and there was no problem in refining seventy-two Qinggang swords.

Of course, if you refine the seventy-two Qinggang swords, the strength you exert will naturally be much weaker. Without long-term nourishment of the Yuan Shen, it can only rely on adding enough Danjing to increase the connection between the Qinggang Sword and the Heart Spirit.

As for whether to use all the Danjing to refine eighteen Qinggang swords, or to refine seventy-two Qinggang swords at the same time, Ishikawa had no idea for a while.

Let's extract the Danjing first.

In "Qinggang Sword Array", there is naturally a method of how to extract Danjing from the demon beast Inner Dan, and this seems to be one of the two cultivation methods in "Qinggang Sword Array".

While extracting the Dan Crystal from the Demon Beast Inner Pill, the monk can strip off the spiritual power in the Demon Beast Inner Pill and refine it into his own spiritual power. This process is very slow, and there is a lot of spiritual power lost in the middle. However, compared to cultivating with spirit stones, it is much stronger, especially some monks who have encountered bottlenecks, and they use this method to forcibly improve their spiritual power in their dantian in order to find an opportunity to break through the bottleneck.

Compared with the method of nourishing the Qinggang Sword with the Yuan Shen and improving the mind, this method is more direct and faster.

Ishikawa took out a first-order demon beast inner pill from his arms, and the spiritual power in this inner pill had already consumed seven layers. Ishikawa slowly used his divine sense to envelop the demon beast inner pill, and began to operate the method, forcibly stripping the spiritual power of the demon beast inner pill.

Soon, the spiritual power in the demon beast inner pill, under the traction of Ishikawa, quickly faded, and the luster of the entire demon beast inner pill became dim.

The less spiritual power there is, the greater Ishikawa's mind will consume, and the more difficult it will be to peel it off, and at the same time, Ishikawa must also pay attention to the fact that this spiritual power cannot be wasted, otherwise it will be too much of a pity.

........................

Two days later, Ishikawa looked at a small vial in front of him, and a wry smile appeared on his face. In two days, Ishikawa only refined four Demon Beast Inner Dan's Dan Crystals, three of which were purchased from Cangcun, and the other was Cangyue Xiong's Inner Dan.

The first three Inner Pills only consumed Ishikawa's time for a few hours, and the Inner Dan of the Quenching Cangyue Bear consumed Ishikawa enough, and in a day and a half, if it wasn't for Ishikawa deliberately letting go of some spiritual power, the refining time would have doubled.

Of course, Ishikawa also got a lot of benefits from the Inner Dan of the Cangyue Bear.

However, time is also extremely expensive. Originally, it was only a few days before the ancient ruins opened, and it would take so much time to refine one, not to mention the remaining three fresh demon beast Neidan.

Ishikawa sealed the three inner pills and retained the spiritual power in them. When you have time, it's not bad to use the Demon Beast Neidan to cultivate.

Ishikawa also found that the less spiritual power the demon beast Neidan remained, the easier it was to temper and the less time it would take.

And the demon beast inner pill in the warehouse generally contains extremely low spiritual power, so it took Ishikawa less than two days to quench all the first-order demon beast inner pills, and the pill crystal was carefully stored in a small jade bottle.

Ishikawa took out four second-order demon beast inner pills, these second-order demon beast inner pills, the remaining spiritual power, is no longer less than one percent, Ishikawa took a deep breath, and wrapped the four second-order demon beast inner pills with spiritual power at once, and extracted spiritual power from them.

The spiritual power in the four demon beasts poured out like a tide, and in an instant, Ishikawa's body was full. Ishikawa's face changed, and he was secretly surprised in his heart, this second-order demon beast inner pill, which was less than one percent of the spiritual power remnants, was actually filled with so much spiritual power.

And the spiritual power in the second-order demon beast inner pill is several times purer than the first-order demon beast inner pill, and it is much easier to cultivate.

Ishikawa was naturally reluctant to waste this pure spiritual power.

In a flash, he entered the immortal mansion, sat upright in the eye of the Gathering Spirit Array, and let the Gathering Spirit Array absorb the spiritual power emanating from Ishikawa's body.

Although the Spirit Gathering Circle will not absorb all the spiritual power, it is better than Ishikawa being outside and wasting it all.

Ishikawa couldn't help but secretly regret it in his heart, if he tempered a second-order demon beast Neidan at a time, this would definitely not happen, and now, Ishikawa could only desperately absorb the spiritual power emanating from it.

The surroundings of the formation were actually already overgrown with spirit grass, and from the outside, it seemed to be no different from other locations.

However, just a short time later, the spirit grass growing in the formation actually grew more than an inch tall, and some spirit grass actually pulled out flower stems and opened spirit flowers.

Thorn bees also flocked to it, as if the spirit flowers in other places were not as attractive as the spirit flowers here.

Ishikawa, who was sitting in the Spirit Gathering Array, had no sadness or joy on his face, and there was no change in his expression.

Three hours later, the Spirit Gathering Circle suddenly flashed with white light, and finally the white light gathered together and injected it into Ishikawa's body.

At this moment, the spirit grass within three zhang of the Spirit Gathering Array suddenly withered at the same time.

Thousands of thorn bees fell to the ground one after another, and even the golden yellow on their bodies slowly disappeared, and finally turned into a transparent color.

And Ishikawa, who was in the middle of the formation, still had his eyes closed, and he seemed to know nothing about what was happening in the outside world. There was a painful expression on his face.

Lin Feng looked at Ishikawa's appearance from a distance, touched his chin and pondered, suddenly stood up, and sat down suddenly, as if he looked a little uneasy. After a while, Lin Feng flew directly onto the Xuantie ball he was meditating on, his eyes slightly closed, as if he hadn't seen Ishikawa.

After a full day, Ishikawa still maintains this position, but if you look closely at Ishikawa's face, you will find an expression that looks like a smile but not a smile.

Ishikawa, who was in this state, knew exactly what was going on, and even Lin Feng's movements, Ishikawa was also clear.

Lin Feng didn't make any moves, if Lin Feng had made any moves just now, I'm afraid he wouldn't be able to meditate and cultivate safely now.

The spiritual power of the four second-order demon beast inner pills, like an eruption, entered Ishikawa's dantian, and then through Ishikawa's dantian, led the origin spiritual power in Ishikawa's body into the spirit gathering array.

This is the only way to avoid wasting spiritual power. But if Ishikawa did this, at the cost of consuming his own origin spiritual power, if Ishikawa didn't take back his own origin spiritual power, I am afraid that he would fall to the eighth layer of the Qi cultivation period. At this point, it was extremely difficult to advance one layer at a time, let alone suddenly drop one layer before entering the ancient ruins.

If you don't want to lose your original spiritual power, you can only convert all the spiritual power in the Spirit Gathering Circle into your own spiritual power. But this process is very slow, and fortunately, the special spirit gathering technique of the Spirit Gathering Circle has greatly accelerated this process.

Just now, Ishikawa took all of his spiritual power for himself. Unexpectedly, he suddenly found that he had reached the peak position of the ninth layer of the Qi training period, and he was only a layer of window paper away from the tenth layer of the Qi training period.

For Ishikawa, who has not broken through for a long time, this is naturally a rare and great thing. After Ishikawa was overjoyed, he was a little speechless in his heart.

If you stop cultivating here, then it won't be so easy to get so close to the tenth level of the Qi cultivation period next time.

If there is another second-order demon beast inner pill, if Ishikawa wants to break through and enter the tenth layer of the qi training period, it is a very easy thing, and now, Ishikawa only has three first-order demon beast inner pills on his body, even if all of these demon beast inner pills are refined, it is not enough to help Ishikawa enter the tenth layer of the qi training period.

With a wave of Ishikawa's hand, the four second-order demon beast inner pills instantly turned into dust, and at the same time, they were included in the small jade bottle by Ishikawa.

At the same time, more than ten vials were placed in front of Ishikawa at the same time, and in each vial, a pill flew out of each vial and entered Ishikawa's mouth.

"Break through!" was Ishikawa's only thought.
