Shen Long didn't plan to abandon the iron-tailed scorpion, according to what Sun Sen said, the ranking of the Heaven and Earth Strange Insect List can only be used as a reference, and the magical power of the spirit insect still depends on the level and bloodline essence purity.

At the same level, the demon scorpion with a high degree of bloodline essence purity is more likely to master a powerful talent supernatural power.

The bloodline essence purity of most demon beasts and demon insects is only one, and the upper limit is not high, and the strange insects that are among the top in the list of heaven and earth strange insects have a relatively high bloodline essence purity, and the upper limit is relatively high.

With the same environment and the same immortal cultivation resources, it is easier for demon beasts and demon insects with high bloodline essence purity to advance.

The demon insects and demon beasts sold on the market, most of the bloodline essence purity is one, it is good to be able to cultivate to the second order, it is particularly difficult to advance to the third order, and the fourth order is not to even think about it.

There are many ways to improve the purity of the bloodline essence of the demon beast, the most common is to let the demon beast devour the corpse of the high-level same kind or the demon pill, and the effect of the elixir is better.

If the iron-tailed scorpion wants to improve the purity of the bloodline essence, it can devour the corpse of the demon scorpion, the higher the purity of the bloodline essence of the demon scorpion, the higher the level, and the better the effect.

In addition, some elixirs can also improve the purity of the bloodline essence of demon beasts, the Imperial Spirit Sect naturally has an elixir in this regard, it is not easy to obtain this elixir, don't think about it for qi refining disciples.

Shen Long put the books back in their place, came to a bookshelf, and his eyes swept over the books on the shelves, "Imperial Weapon Formula", "Illustrated Magic Weapon", "Atlas of Hundred Soldiers", "Outline of Magic Weapons", ······

The classics on this bookshelf are mainly to introduce the weapons used by immortal cultivators, from low to high, they are divided into magic weapons, magic weapons, and spiritual treasures, and magic weapons are divided into four grades: lower, middle and upper poles.

As for the Lingbao, Shen Long is not clear.

He mainly wanted to find out the origin of the Imperial Spirit Tower, so as to facilitate the further development of the function of the Royal Spirit Tower.

It didn't take long for Shen Long to pick up a golden book, and the three big characters "Pagoda Record" were written on the book cover.

Shen Long sat down on the stool and looked at it.

"Pagoda Record" records a variety of tower types of magic weapons, with different functions, most of them are trapping or killing enemies, and there is no pagoda with the same function as the Royal Spirit Pagoda.

These pagoda magic weapons have all been used by high-level monks, and the monks of the Imperial Spirit Sect have seen or heard of them, recorded them, and compiled them into the pagoda record.

Some monks of the Imperial Spirit Sect know that they cannot enter a higher realm, so they will record what they have seen and heard before sitting down and compile a personal biography.

The Imperial Spirit Sect will send someone to sort out these contents, and the personal biography will be intact, and the content will be divided into multiple parts, such as the customs and habits of different races, and the characteristics of supernatural powers, which will be compiled into the classics that introduce the race, and the spirit beasts and spirit insects, then compiled into the classics that introduce the spirit beasts, and the magic weapons that have been seen or heard of will be compiled into the classics that introduce weapons.

This is a huge project, and it is also a kind of heritage, and it will be much more convenient for the disciples of the Imperial Spirit Sect to consult the relevant information.

The higher the number of layers in the Scripture Pavilion, the more precious the books stored, and the higher the cultivation of the Imperial Spirit Sect monks who guarded it, the stronger their strength.

Shen Long finished reading "Pagoda Record", and checked a lot of classics, but he didn't find a magic weapon with a similar function to the Imperial Spirit Pagoda, there was no one on the first layer, maybe there were relevant records in the higher-level classics.

Shen Long felt that the time was almost up, left the Hidden Scripture Pavilion, and returned to Qingyun Peak.

Back at Qingmei Courtyard, Lin Cheng had already left.

Shen Long walked into the Qingmei Pavilion and saw a transmission note floating in mid-air.

He grabbed the transmission note and crushed it, and Lin Cheng's voice sounded: "Senior Brother Shen, the insect removal is over, I have already gone back, this time tomorrow, I will come again, if it is inconvenient for you and you need to change the time, just say hello to me." ”

Shen Long activated the ban, left the Qingmei Temple, and walked towards the mountain.

Walking into the Teaching Pavilion, Shen Long saw many fellow disciples, and Qian Dafu was chatting with Ye Yuqing.

Shen Long walked over and asked, "Senior Brother Qian, how do you sell the Silver Marrow Spirit Rice?" I want to buy some. ”

"Ten catties and three spirit stones, fifty catties and fourteen spirit stones, how much does Senior Brother Shen want to buy? The more you buy, the cheaper it gets. ”

Qian Dafu said enthusiastically.

"I'll buy fifty pounds! When will I be able to pick up the goods? ”

Shen Long asked.

"Deliver before dinner, I'll contact the seller right away."

Qian Dafu said, got up and left the Granting Pavilion.

Shen Long chatted with Ye Yuqing for a while, and Sun Sen came over.

After the roll call, Sun Sen began to teach, mainly about the basic cultivation knowledge, from the introduction of spiritual roots, to magic weapons, pills, formations, and talismans.

Shen Long and others can ask questions, and Sun Sen will answer.

Two hours later, Sun Sen announced the end of class, and Shen Long and the others left one after another.

As soon as Shen Long walked into the Lingshan Pavilion, he saw Qian Dafu at a glance.

"Senior Brother Shen, what you want has arrived."

Qian Dafu said enthusiastically.

"Let's talk to my lodgings after dinner."

Shen Long said.

He queued up to receive Lingshan and ate noodles for dinner, with a bowl of noodles and two steamed buns per person, and the noodles were unlimited.

After eating and drinking, Shen Long and Qian Dafu left the Lingshan Pavilion.

Back at Qingmei Courtyard, Shen Long said, "Senior Brother Qian, take out the Silver Marrow Spirit Rice!" ”

Qian Dafu took out a white rice bag and handed it to Shen Long.

Shen Long opened the rice bag, and a rich rice fragrance came to his face, and the rice bag contained a large amount of silver spiritual rice, the rice grains were full and crystal clear.

"Senior Brother Shen, you pour the Silver Marrow Spirit Rice into the rice jar and examine it carefully."

Qian Dafu took out two half-person-high rice bowls and said.

"No, I can trust you."

Shen Long took out fourteen spirit stones and handed them to Qian Dafu.

"No, no, it's better to check it in person, it's good for everyone, you just watch from the side."

Qian Dafu is colorful.

In business, if Shen Long said that the silver pith spiritual rice was mixed with cheap spiritual rice in the future, Qian Dafu would be speechless.

It's best to check it in person.

Shen Long did not refuse, and let Qian Dafu pour the silver pith spirit rice in the rice bag into one rice jar, and then use a wooden scoop to move the silver marrow spirit rice to another rice jar.

Shen Long didn't see any other spiritual rice, the rice grains were full, the color was bright, and the quality was good at first glance.

"If you need anything in the future, I will look for you."

Shen Long said that he was very satisfied with Qian Dafu's way of doing things.

"Okay!"

The smile on Qian Dafu's face deepened, and he put the spiritual rice into a rice bag and handed it to Shen Long.

After chatting a few words, Qian Dafu said goodbye and left.

Shen Long walked into the Qingmei Pavilion, came to the basement, and entered the Imperial Spirit Pagoda.

The Fire Rock Beast stepped out of the Imperial Spirit Pool and let out a loud roar.

Shen Long took out a handful of silver pith spirit rice and sprinkled it on the ground.

The flint beast smelled the rice and ate it.

It ate two catties of silver pith spirit rice and became a little closer to Shen Long.

According to the method taught in the classics, Shen Long trained the Fire Rock Beast to do some simple movements, and commanded it to release spells to attack the enemy.
