Nine Transformations of the True Spirit.

Chen Yuan hesitated for a moment and said, "When I left the Demonic Plain with you, I already sacrificed a hundred magic cores. Do I need to sacrifice again after returning to the Demonic Plain?"

The green robed spirit shook his head: "Young friend, you can leave directly through the altar."

Chen Yuan pondered for a moment and said, "I want to sacrifice again, but I don't have enough level 7 magic cores..."

The green-robed formation spirit smiled and said, "My friend, don't you want that Qingliu hermit to notice that you have left the Demonic Plain?"

Chen Yuan nodded, and the green-robed formation spirit raised his sleeves and flicked them, and nearly a hundred magic cores appeared out of thin air in front of him.

"I'll give you these level 7 magic cores, but I don't have many level 9 magic cores, so you need to prepare them yourself."

Chen Yuan was delighted and put all the magic cores into the mustard seed ring: "Thank you for the gift, senior. I still have a few level nine magic cores."

Upon hearing this, the green-robed monk suddenly asked, "The expansion of the Donghua Continent Demon Realm should have infected many demon beasts. Did you gain anything after entering it, my friend?"

Chen Yuan's heart moved, and he answered truthfully: "When I was fighting with the Demon Lord, I took the opportunity to kill many monsters."

The green-robed monk smiled slightly and said, "According to the rules set by the master, if someone can produce a large number of high-level magic cores after passing the magic source trial, he will be eligible to choose another treasure from Tongtian Pavilion. How many magic cores do you have?"

Chen Yuan's eyes lit up, and he immediately took out all the magic cores in the mustard seed ring: "I still have six level nine magic cores and thirty-one level eight magic cores, all here. I wonder if I can exchange them for another treasure?"

Seeing so many magic cores, the green-robed array spirit showed a bit of surprise on his face: "My friend, you are very clever. Although the magic beasts have no intelligence, they are not that easy to deal with..."

"Yes, my friend has mastered the Zhuyan True Fire, so it will be easy for him to deal with those monsters that have just been infected by the evil spirit."

Chen Yuan smiled and said, "Senior, you have a keen eye. I was able to achieve such a harvest by relying on the Zhuyan True Fire and taking advantage of it."

The green robed formation spirit smiled and said, "My friend, there is no need to be modest. Being able to refine the Zhuyan True Fire is a skill."

"These magic cores will allow you to receive a treasure, but you can't choose arbitrarily like before."

Chen Yuan was in high spirits: "I wonder what treasure this junior can choose?"

The green robed spirit said, "If you want Moonlight Dew, you can take two drops and exchange them for a demon pill. You can choose a level 10 demon pill, but you cannot choose a powerful bloodline such as the Golden Dragon, Ice Phoenix, or Black Turtle..."

"Of course, you can choose other treasures, but the most suitable treasures for you in Tongtian Pavilion are the Moonlight Dew and the Demon Pill."

Chen Yuan heard this and no longer hesitated: "Then I will choose two drops of Moon Dew."

The green-robed formation spirit nodded, raised his sleeves and flicked them, and most of the magic cores disappeared, leaving only three level nine magic cores.

Then he raised his hand, and a jade bottle appeared out of thin air in his palm. He handed it to Chen Yuan: "My friend, keep these two drops of Moonlight Dew. The remaining three magic cores are for you to sacrifice on the altar."

Chen Yuan took the jade bottle with both hands, and without even checking it, he put it directly into his internal space.

After he refined the thirty-three body-tempering elixirs, his body was greatly strengthened and he was not far from the bottleneck of level ten.

After taking these two drops of Moonlight Dew and being infused with starlight for several years, I should be able to reach this bottleneck.

But it is absolutely impossible to rely on these two drops of moonlight dew to improve the physical body to a higher level and become comparable to a tenth-level demon king.

According to the experience of refining the true spirit blood twice before, Chen Yuan's current physical strength is still insufficient if he wants to refine the Green Ox Demon Pill. He must reach the level of a tenth-level demon king.

In this case, one would have to wait a few more years to strengthen the body with the starlight, or find other rare treasures to strengthen the body.

But the Body Tempering Spiritual Herbs are extremely rare, and treasures like Moonlight Dew are even rarer in the world. Where can I find them...

Suddenly, Chen Yuan's heart moved and he thought of the Kuixing ancestor outside Tongtian Pavilion.

A cold light flashed in his eyes, and he asked, "I have two things in my hand, which are quite strange. Please take a look, senior."

As he spoke, he took out the jade brick tainted with evil spirit and the ancient fragment from the mustard seed ring and presented them with both hands.

"This jade brick seems to be related to somewhere deep in the Demonic Plain. I originally thought it was a broken brick from the Tongtian Pavilion, but the Tongtian Pavilion is intact..."

The green robed spirit took a quick look and frowned, "This jade brick has nothing to do with the Tongtian Pavilion. It is a broken brick that was left outside after the altar was damaged."

Chen Yuan looked surprised: "Will the altar be damaged as well?"

The green robed spirit nodded, his expression somewhat solemn: "My friend, you may not know that the three major trials on Tongtian Island are the three secret spaces in the other world that the master moved to the island."

"The fierce beasts in the Ice and Fire Realm and the thunder beasts in the Wind and Thunder Sea are all bred from creatures from other worlds. Only the demon beasts in the Demonic Origin are infected by demonic energy."

"In the deepest part of the Demonic Plain, there is a source of demonic energy. The master specially set up forty-nine altars to seal it up, and let the monks on the island enter the Demonic Plain to hunt monsters, collect demon cores, and weaken the demonic energy."

"But after Tongtian Island fell, no cultivators entered the Demonic Plain for more than 30,000 years. The demonic energy became denser and denser, and several level 10 demonic beasts were born. They destroyed thirteen altars one after another, leaving only thirty-six."

Chen Yuan's expression changed slightly: "If there are level 10 monsters in the Demonic Origin, how can the monks who enter the island complete the trial?"

The green-robed array spirit explained, "Those level 10 monsters are staying in the deepest part of the Demonic Plain, absorbing the demonic energy and improving their cultivation. They won't wander around. As long as you don't go into the deep part of the Demonic Plain, you'll be fine."

Chen Yuan felt relieved. No matter how strong he was, he was not a true great cultivator. If he encountered a level 10 monster, he would most likely not be a match. The green robed formation spirit sighed softly, "No one can control these level 10 monsters. They are getting stronger and stronger. If this continues, a divine monster will eventually be born."

"Then the Demonic Plain will become a restricted area, and no one will be able to pass the test and enter the Tongming Palace."

Chen Yuan was puzzled and asked: "Senior controls the entire Tongtian Island, but can't he deal with a mere level 10 monster?"

The green robed spirit shook his head: "According to the rules set by the master, I cannot interfere with the trial."

"My master had never expected that the demons and monsters would go to great lengths to ask five great masters of the Void Refining Sect to descend upon the human world and launch a counterattack. This caused the Tongtian Island to fall, and I fell into a deep sleep. The Demon Origin showed signs of losing control..."

Chen Yuan's mind was moved: "If I help you to eliminate these level 10 monsters, I wonder if I can get some treasures from Tongtian Pavilion in exchange?"

The green robed spirit was startled, and showed an interested look: "This has never happened before... But protecting Tongtian Island is my primary responsibility. If you can really eliminate those level 10 monsters and choose some treasures, it will naturally not be a problem."

"But I want to remind you, my friend, those level 10 monsters are extraordinary. They have survived for at least tens of thousands of years. They are very powerful and have developed some basic intelligence. Even if you use the Zhuyan True Fire, it won't have much effect."

Chen Yuan said sternly: "I know my own limitations. I will wait until my cultivation level improves before entering the Demonic Plain to help you deal with those level 10 monsters."

Speaking of improving his cultivation, he couldn't help but think of the Kuixing Patriarch, and asked: "May I ask, Senior, why can't we fight each other after entering Tongtian Island, otherwise there will be thunder from the sky?"

The green robed spirit smiled and said, "Tongtian Island gathers the most outstanding cultivators from all sects in the human world. How can we let them kill each other?"

"The master has set a rule that anyone who engages in private fighting will be killed without mercy."

"Only when you enter those incomplete secret spaces where monks train, are you allowed to fight each other, but you are not allowed to kill each other."

"It's just that the monks who enter the island now are not considered to have truly joined Tongtian Island. Even if someone dies, I won't care."

Chen Yuan suddenly realized something, and a thought quietly rose from the bottom of his heart. He clasped his fists and bowed: "Thank you for clearing up my doubts, senior."

The green robed spirit gave him a meaningful look and walked towards the gate: "Follow me, little friend."

Chen Yuan followed, walked out of Tongtian Pavilion and came into the valley.

The green-robed formation spirit raised his sleeves and flicked them. A white light flashed and the two figures disappeared.

Chen Yuan's eyes blurred and he felt a slight squeezing sensation. When he came to his senses, the thick spiritual mist around him disappeared without a trace. The sky and the earth became dark and filled with black fog.

He raised his eyes and saw Buddhist Qingliu sitting cross-legged with his eyes closed and regulating his breathing a hundred feet away.

He returned to the Demonic Source, and even his position did not change.

The green robed spirit stood in front of him and said with a smile: "I will not disturb you, my friend. I hope that you can make further progress in a hundred years."

Chen Yuan clasped his fists and bowed: "I will definitely keep in mind the advice of my predecessors. If you want to accomplish extraordinary things, you must have extraordinary abilities. I will be down-to-earth and strive to be the first step at every step."

The green-robed formation spirit nodded slightly, and its figure slowly disappeared.

Chen Yuan stood up, and after a while, Qingliu Lay Buddhist also opened his eyes and flew over: "Daoyou Chen, has your true energy been restored?"

Chen Yuan smiled slightly: "Thank you for waiting, fellow Daoist, we will go to the altar in front, sacrifice the magic core, and complete the trial."

Qingliu Lay Buddhist was surprised and asked, "Fellow Daoist, are you not going to the depths of the Demonic Plain to look for Tongtian Pavilion?"

After the two met up, Chen Yuan secretly told him about the Tongtian Pavilion.

After killing Kunhai, Old Ancestor Yuntian and others, they will go looking for this ancient relic.

If not for this, Chen Yuan would not have recovered his true essence in the Demonic Source, and would have been directly teleported to the Tongming Palace through the altar.

Chen Yuan shook his head slightly: "Tongtian Pavilion is illusory, and that sect leader Lv Fang is fickle, and there are many untrue things in his words. Don't trust them easily. It's better to be safe and complete the trial."

Qingliu Lay Buddhist nodded: "Let's follow your advice."

He had no idea about Tongtian Tower. He just wanted to find the three thousand year old Qingfeng Bamboo and obtain the true inheritance of the ancient Confucian and Taoist monk.

It was exactly what Chen Yuan wanted that he didn't go looking for Tongtian Tower to avoid unnecessary complications.

With a flash of light, the two of them flew into the sky and arrived at the altar a hundred miles away, where Elder Gu and the other three were meditating while waiting for Chen Yuan and the yellow-haired old man.

Mr. Qingliu took out a hundred magic cores, and Chen Yuan followed closely behind.

The altar lit up with a black light, and after a few flickers, two hundred magic cores suddenly exploded, and the pure demonic energy contained in them all poured into the altar.

The teleportation array suddenly lit up, and a white beam of light shot up into the sky, enveloping Chen Yuan and Qingliu.

The next moment, a flash of white light appeared, and the two figures disappeared. (End of this chapter)
