There are also a lot of classics in the Xin Ru hook storage bag.

After a cursory look at the Qingyunmen's exercises, Ishikawa began to focus on studying Xin Rugou's cultivation experience and correspondence.

Generally speaking, cultivators will record the problems or achievements they encounter in their cultivation, so that they can use them for later generations when they perceive or advance on weekdays.

Therefore, basically every monk has his own cultivation experience, of course, the most essential part of cultivation, most monks will not record it.

Even so, the cultivation experience of a monk in the foundation building period has such a far-sighted guiding significance for Ishikawa. Ishikawa naturally carefully collected this experience.

Among Xin Rugou's correspondence, there was one that particularly caught Ishikawa's attention. This is a yellowed secret letter, written more than ten years ago, when Xin Rugou was still a monk at the eighth level of Qi cultivation. There is nothing special about the contents of this letter.

At that time, Xin Rugou was a monk in the Northern Xu Kingdom, and he was very fond of a female cultivator named Zhong Baoyi, but the female cultivator was idle and had poor qualifications, and she was unable to build a foundation in this life and cut off contact with Xin Rugou.

Ishikawa speculated that this might be the main reason why Xin Rugou worshiped Qingyunmen.

Although Qingyunmen is the number one sect in the Southern Liang Kingdom, it is definitely not good for an eighth-layer disciple who has entered the sect halfway and has poor qualifications.

But Xin Rugou only took ten years to build a successful foundation. This is what surprised Ishikawa the most.

Ten years of foundation building is a very rare thing for ordinary monks.

Except for the Zhuji Dan, the other various resources, just the peak of the eighth to tenth layers of the Qi cultivation period, if there are not enough pills and spirit stones, ten years may not be able to cultivate.

Then Xin Ru Hook must have the secret of obtaining a large number of spirit stones and pills.

At this time, Ishikawa suddenly thought of the secret behind the huge waterfall in Qingcang Mountain. Xin Ru Hook was cautious before entering, and did not hesitate to fight with the elders of the Spirit Sword Sect in order to protect the secret.

In an instant, Ishikawa seemed to understand something, the secret behind the waterfall may be the biggest reliance of Xin Ru Hook.

If you can successfully build the foundation and leave the ancient ruins, then Ishikawa will definitely go to Qingcangshan Waterfall and take a closer look.

In view of this, Ishikawa paid more attention to the fragments and debris in Xin Ru's storage bag, and did not dare to discard them in the slightest.

In addition to the treasures such as spirit stones, spirit grass, ores, spirit weapons, and demon beast bones that can be identified, there are many strange jade plates and other things in Xin Ru Hook's storage bag, and the array disk of the magic circle.

Ishikawa took out a separate storage bag and packed it for later use.

Looking not far away, the Qingyunmen monks had increased a lot, and Ishikawa secretly complained in his heart. I just got a lot of spirit stones from Xin Rugou, and it is not a problem to stay here for a month, but staying like this is not a way after all.

Ishikawa decided to wait and see for a few more days, if there was a trend of decreasing the number of Qingyunmen monks, he could wait a few more days, but if the number increased, Ishikawa would have to fight hard.

If you want to do it, you must first sharpen your tools. Danjing has long been ready, since he got the eighteen ribs of the demon Jiao, Ishikawa has long had the idea of refining the Qinggang sword, and now although there is not much time, Ishikawa can't hold it.

If you can refine these eighteen Qinggang swords, it will definitely be able to greatly improve Ishikawa's strength.

Moreover, the eighteen demon Jiao ribs are almost identical, and they do not need to quench ore like refining other magic weapons, which saves a lot of time at once.

His consciousness moved slightly, and Ishikawa appeared in the immortal mansion.

At this time, the immortal mansion was almost covered with spirit grass, and no matter where Ishikawa was refining, it was bound to cause a lot of losses. There are only two places, which are still empty.

One is above the cave of the alien beast, and the other is the natal stone tablet of Ishikawa.

After a slight hesitation, Ishikawa still came to his natal stone tablet, and with a wave of his hand, eighteen demon bones appeared in front of Ishikawa, lined up.

With another wave of his hand, a fist-sized silver ball and egg-sized off-white beads swirled in the air.

This is the mythril and cold iron that Ishikawa stole from the beast's mouth. This rare material can no longer be measured by the product rank, which is one of the reasons why Ishikawa uses them to refine the Qinggang Sword.

The seventh-order demon Jiao ribs, after being tempered by heavenly thunder, the preciousness can be imagined. If it is mixed with materials such as black iron and red copper, it is definitely a tyrannical thing, and even if it is a material from the foundation building period, it is not within the scope of Ishikawa's consideration. What's more, the materials from the foundation building period have already been used to repair the Tianyuan puppet.

Ishikawa has a more long-term plan, that is, once and for all, the eighteen Qinggang swords that he has refined, slowly nourished with the Yuan Shen, will definitely become a great weapon for Ishikawa.

So in Ishikawa's storage bag, Mithril and Cold Iron are worth Ishikawa's use.

The power of this particular material depends on the amount used. For example, if you make a sword entirely out of Mithril, then the sword can be completely dismantled.

Ishikawa doesn't have so much Mithril to squander, and a piece of Mithril the size of a fist is already extremely rare, and if you add it all, it should be enough to use. It's just that cold iron is too scarce, but it's barely enough.

Mithril and cold iron spun rapidly in the air, and in a short time, they turned into a viscous shape under Ishikawa's tempering.

Ishikawa released his divine consciousness and wrapped the eighteen demon Jiao ribs with divine consciousness, and these eighteen ribs were born in the same demon Jiao's body, and they were nourished by the same qi and blood, and they were conceived for thousands of years. Under the tempering of the Thunder Tribulation, it is already close to a piece of spiritual weapon.

Ishikawa's divine sense could feel the thunder power in his ribs. These thunder forces were born from the heavenly thunder, and after entering the body of the demon jiao, they grew and grew each other, and they have become part of the bones of the demon jiao.

It can be said that the value of the demon Jiao's ribs has doubled because of the tempering of the thunder tribulation, and it is also difficult to temper because of the thunder tribulation.

Ishikawa divided the mythril and cold iron evenly into eighteen parts, each of which turned into a silver dragon and circled around a rib.

The arc of electricity on the ribs flickered, resisting the invasion of Mithril Iron.

This made Ishikawa a little embarrassed, and if he forcibly fused, he was afraid that it would cause irreparable damage to his ribs. Mithril and Cold Iron are precious, but they can be found again if they are lost.

But the ribs of the seventh-order demon Jiao, and they are eighteen identical, and the ribs of the demon Jiao that have been tempered by the thunder tribulation, I am afraid that there will not be a few pairs between heaven and earth, so Ishikawa did not dare to be too anxious, but waited slowly.

Compared to refining magic weapons before, refining this Qinggang Sword seemed to be much easier. The only thing Ishikawa had to do now was wait.

This is the fifth day Ishikawa has been here. Ishikawa would visit the Qingunmen monks' colony several times a day.

Today, it is a little strange that there are many fewer monks in Qingyunmen overnight. There were dozens of people, but less than ten remained.

This made Ishikawa wonder.

In the past few days, there have also been many monks who want to rush over desperately, but without exception, they all died under the sword of the Qingyunmen monks.

Although there are not many of them, there are a few of them every day.

Could the monks of Qingyunmen change places because the number of monks killed here is too small?

Ishikawa thought about it, and this explanation was the most reasonable.

"Bang, bang!" The blue arc struck the silver dragon formed by the convergence of Mithril and cold iron, and began to circulate in the silver dragon's body.

This is a good sign, if the silver dragon also has a thunder arc in its body, then it will be much easier for the two to fuse.

However, there was no trace of a smile on Ishikawa's face, the time for the two to merge was not short, but Ishikawa's time was urgent, and the moment he entered the east side of the ancient ruins, Ishikawa's safety could also be added to the point.

If there was no Qingyunmen monk to guard it, Ishikawa could have separated a trace of his divine sense in the Immortal Mansion, paid close attention to the refining of the Qinggang Sword, and then set off.

But now that there are more than a dozen Qingyunmen monks guarding him, Ishikawa will have to do it with all his strength if he wants to pass by.

Ishikawa originally planned to ask Lin Feng to help, but Lin Feng looked at the blue thunder arc and waved his hand again and again, not even daring to enter within ten zhang.

"That's it!" Ishikawa shook his head, while dividing his divine sense, observing the refining of the Qinggang Sword, on the other hand, he also paid close attention to the movements of the Qingyunmen monk.

At this moment, a pair of a team of more than ten monks, from west to east, were rushing towards the Qingyunmen monks.
