A few days passed in a flash, and Mo Yuan went back and forth between his residence and the Hall of Transmission of Gong in the past few days.

The experience of fighting against Feng Yue in the Scarlet Forbidden Land gave Mo Yuan a taste of the sweetness of high-level spells.

When fighting against Feng Yue, if it weren't for Mo Yuan's preparation of a junior and high-level spell in advance, the Burst Fireball Technique, then Mo Yuan wouldn't even be able to break through the defensive light shield released by Feng Yue's supreme magic weapon, Huang Luo Umbrella.

With Feng Yue in possession of the Flying Knife Rune Treasure, the Huang Luo Umbrella, and the Cloud Boots, once Mo Yuan could not break through the opponent's defenses, he could only rely on the Iron Eater's thick defense and the Escape Technique to escape.

Fortunately, luck is on Mo Yuan's side.

After Mo Yuan returned from the forbidden land, whenever he reflected on that battle, he was glad that he had lit up the earth fire map on the jade book before entering the forbidden land, and had prepared high-level spells with strong attack power in advance.

On the first floor of the Chuangong Building, he usually lectures on beginner and low-level and elementary middle-level spells, but there will also be some disciples who specialize in spell runes and gather together to discuss the cultivation experience and talisman making experience of primary and high-level spells.

They practice high-level spells not to cast them in battle against the enemy, but to refine talismans, which need to be learned before they can be drawn on the rune paper.

In the past few days, Mo Yuan has been mingling among these disciples, and has learned a lot of experiences about cultivating high-level spells and talisman making that he had never known before.

As for the talisman making, Mo Yuan is also interested. This is not only the reason for the spirit talisman recorded in the Imperial Spirit True Formula, but also the reason for the "Heavenly Rune Sutra" obtained from the Forbidden Land White Bone Storage Bag.

There are many unique talismans of the Heavenly Rune Gate recorded in the "Heavenly Rune Sutra", these talismans have different effects, and they cannot be bought in the outside world, if Mo Yuan wants to obtain them, he can only study the way of making talismans by himself and draw them.

In addition, Mo Yuan also spent spirit stones on the second floor of the Chuan Gong Hall to search for some books that he was interested in before, but could not search because of the lack of spirit stones.

Among them, there are mainly some information about demon beasts, the spirit beast mountain specializes in spirit beasts, and there are many books about demon beasts recorded in the hall.

Among them, there are countless books that explain the types of demon beasts, the habits of the demon beast race, the food of the demon beast, the strengths and weaknesses of the demon beast, how to easily capture the demon beast, how to transform the demon beast into a spirit beast, how to cultivate the spirit beast, and so on.

However, Mo Yuan was not interested in these, but some books about the materials of demon beasts, which explained how the various parts of various demon beasts worked for the monks and how they could be used.

Mo Yuan has never forgotten the matter about the blood of the demon beast, the spirit spirit secret he cultivated does not have any powerful supernatural powers, and the ability of the spirit control spirit essence has to rely on the jade book spirit catalog to perform, and for the spirit control catalog, the most important thing is the origin of various living beings.

The essence blood of demon beasts is a kind of origin of living beings.

If the jade book wants to include demon beasts like the "Earth Flow Fire Spirit", the demon beast essence blood and the demon beast spirit soul are indispensable, and the demon beast essence blood, a demon beast material, is a rare thing in today's immortal cultivation world, and it will not appear on the market at all.

For monks, the demon beast essence blood cannot be taken directly because it contains violent demonic power, and is more used for medicinal refining.

The demon beast essence blood needs to be extracted from the flesh and blood of the demon beast, and the difficulty is extraordinary.

The energy spent on extracting essence blood and the return brought by essence blood to the monks are not symmetrical at all, so as early as in the ancient immortal cultivation world, such a thing as demon beast essence blood has been eliminated, and now, it is almost extinct.

In the alchemy refiner, the places that really need to use the essence blood of the demon beast are also replaced by the blood of the demon beast, although the effect of the blood of the demon beast is not as good as the blood of the demon beast, but in the case of the monk's intention to eliminate and ban it, the effect that the blood of the demon beast can play is enough to meet the demand.

When there is no demand for an item, there is naturally no supply.

In today's immortal cultivation world, the essence blood of demon beasts is something that is even rarer than the 10,000-year-old spiritual liquid.

Mo Yuan needed demon beast essence blood, but if he wanted to obtain it from the outside world, it was almost impossible, so he could only find a way to extract it himself.

There was a record of the demon beast essence blood in the ancient books that Mo Yuan had queried earlier, and if he wanted to extract the demon beast essence blood, he had to at least build a foundation monk to do it.

After the monk builds the foundation, he can cast the Taoist true fire and use the real fire to extract the essence blood of the demon beast.

However, its difficulty is no less than the difficulty of the foundation building monk to form a golden pill, and the higher the level of the demon beast, the more difficult it is to extract essence blood.

There is only one simple and crude method for extracting the essence blood of demon beasts in ancient books - calcining the real fire, removing the turnips, exhausting the magazines, and producing the essence and blood.

Mo Yuan will be able to obtain two Tsukidans immediately, with his talent of three spirit roots, plus cultivation to the peak of the thirteenth layer of Qi refining, and if he has already taken one Tsukidan, if he takes two Tsukidans again, although he dare not say 100% of the hope of successfully building the foundation, it is not low.

According to the content of "The Way of Building the Foundation" summarized by Spirit Beast Mountain, it is speculated that Mo Yuan will most likely be able to successfully build the foundation this time, and after successfully building the foundation, Mo Yuan needs to find a way to refine the essence blood of the demon beast.

The patterns included in the Imperial Spirit Catalogue gave him such a boost that Mo Yuan had already experienced, and he would never give up no matter what.

In the past few days, in addition to discussing the experience of beginner and high-level spell cultivation and talisman making with his fellow disciples, Mo Yuan is trying to find a better way to extract the essence blood of demon beasts.

It's a pity that after a few days of wandering around on the second floor of the Chuan Gong Hall and spending some spirit stones, Mo Yuan was not able to find such a method.

The half-moon period agreed before had arrived, and on this day, on the first floor of the Chuan Gong Palace, Mo Yuan was mixed in with several older fellow senior brothers, all of whom were people who had already built a hopeless foundation and buried themselves in the way of developing talismans.

Mo Yuan rarely spoke in the crowd, and spent more time listening to the senior brothers' high opinions, nodding thoughtfully from time to time, expressing his agreement with the other party's remarks, and he himself also had such a view, and at this time, he could often gain the recognition and encouragement of the senior brothers who spoke.

When a few senior brothers were silent for a while, they threw out some questions in time to seek the answers of several senior brothers, and at this time, these senior brothers and sisters who had no hope of building a foundation and had reached the end of their immortal path would enthusiastically turn into human teachers and generously share some of their own practice or talisman making skills.

However, this is not as simple as it seems on the surface, and it is not something that can be done by complimenting the other party a few words.

If you want to join this discussion, you either have to be someone who is also proficient in the way of developing talismans, or you have to be young, have a high level of cultivation, and are expected to build a foundation, or you have to be a disciple or junior of a certain uncle in the sect.

Mo Yuan is the second of them.

Although he is not young at the age of thirty-eight, he is still among the best age to build a foundation, and this age is not much older than the cowherding baby in the secular world for immortal cultivators, and even belongs to the kind of little milk baby who doesn't know if the cow runs away.

At this time, just as one of the old-looking senior brothers was making a big statement, outside the Hall of Transmission of Gong, a transmission note flew in from outside the door and floated in front of Mo Yuan to levitate quietly.

Seeing this, the senior brother who spoke first looked surprised, and then reacted to something, a wave appeared in his eyes, and he looked at Mo Yuan, who was sitting quietly on the side, with a slightly envious gaze.

Several of the same disciples around him were also like old men, and after being slightly stunned, they all looked at Mo Yuan with envious eyes.

Mo Yuan looked at the floating transmission note, got up and bowed slightly to several senior brothers, apologized slightly, and then raised his hand and pointed, and a spiritual light shot out and fell on the transmission note.

The light of the transmission note flickered, and a few thin threads of spiritual energy floated out of it and flew into Mo Yuan's ears, and then the spiritual light of the transmission note dimmed, and the "Peng" spontaneously combusted, and instantly turned into a cloud of ashes and fell from the air.

Mo Yuan raised his hand and swept the spiritual wind, and the ashes disappeared.

At this time, the old man who had spoken earlier spoke up:

"Today is the day for the disciples who participated in the blood forbidden trial to receive the Zhuji Dan, and the junior brother also participated in this trial, and it is rumored that he has gained a lot, presumably this transmission note is to inform the junior brother to receive the pill, but the senior brother has to congratulate the junior brother in advance."

Several other senior brothers also bowed their hands one after another, and there was no lack of envy in their tones.

Mo Yuan bowed his hands one by one, said polite and modest words in his mouth, and exchanged a few words of greeting before he said goodbye and turned around and walked out of the Chuan Gong Palace.

On the way out of the Gong Gong Palace, the disciples who found the previous movement around them all bowed their hands to Mo Yuan one by one, and Mo Yuan thanked Mo Yuan one by one regardless of whether he knew it or not.

In a short way, Mo Yuan seems to have walked a life.

Out of the hall, Mo Yuan carried the wind control trick, and under the amplification of the cloud-stepping boots, he quickly disappeared outside the palace gate, leaving behind the envious and jealous gaze.

"Senior Brother Mo left this time, see you next time, I may have to perform the disciple ceremony and call me uncle." Among the few people who were originally discussed, one said in a slumber tone.

"Yes, but this is everyone's fate, but we can't envy it." Someone said indifferently.

"Is that Senior Brother Mo, who is rumored to have contributed the most among the returnees of this Blood Forbidden Trial?" A young disciple asked in surprise.

"Is that Senior Brother Mo? It's really worthy of the jade-faced pretty gentleman you said, senior sister. A young female disciple whispered and laughed at the senior sister next to her.

"Immortal cultivators, be like this!" Someone argued.

In the Hall of Meritorious Service, everyone was discussing, but all of this was no longer known to Mo Yuan, who had left the Hall of Meritorious Service.
