The ultimate boundary of Huangji's extreme realm requires an explosive force of a hundred oxen.

  Zhang Ruochen, due to the advantages of his cultivation method and the experience from his previous life, used the Nine Heavens Divine Emperor Scripture to open up thirty-six meridians in his body. With the assistance of various cultivation resources, he reached the state of No Upper Extreme Boundary in one go.

  If there was no Nine Heavens Ming Emperor Scripture, or if there was no cultivation experience from the previous life, even if Zhang Ruochen had more cultivation resources, it would be impossible to reach the Supreme Extreme Realm.

  Kong Xuan didn't cultivate the Nine Heavens Ming Emperor Scripture, but she cultivated one of the strongest techniques of the Peacock Half-Human Tribe - the Peacock Sacred Canon, which allowed her to open up twenty-seven meridians in her body.

  She is already considered quite formidable among young warriors.

  Although it is impossible to break through the ultimate realm, there is still a glimmer of hope to break through with the power of ninety cows.

  "Master, my cultivation has already reached the pinnacle of the Great Perfection of the Yellow Extreme Realm, and it's fundamentally impossible for me to make any further progress."

  Zhang Ruochen smiled and said, "If you didn't have the Half Sacred True Liquid, your cultivation naturally wouldn't be able to advance any further. But with the assistance of four drops of Half Sacred True Liquid, your cultivation can still advance a bit."

  Demigod Elixir can expand the Qi pool of a Yellow Extreme Realm warrior, making their Qi pool more vast. At the same time, Demigod Elixir can also temper a warrior's physique, making Kong Xuan's physique even stronger.

  Even when Zhang Ruochen was in the Huang Ji border, he didn't have the opportunity to use the Semi-Holy Elixir to temper his martial body. It can be said that Kong Xuan's resources were even more abundant than his.

  Zhang Ruochen didn't care about this bit of cultivation resources. If he could cultivate Kong Xuan and make him a top-notch expert, then in the future, he would have another powerful helper by his side to help him do some things that he himself found inconvenient to do personally.

  "With your current cultivation, it's impossible for you to refine the Semi-Saint True Liquid. I'll lend you a helping hand." Zhang Ruochen said.

  Zhang Ruochen was refining the first drop of Semi-Saint True Liquid when he was in the late stage of Xuanji Realm. With his current cultivation, he could barely withstand the powerful medicinal properties of the Semi-Saint True Liquid.

  With Kung Xuan Huang's extremely high level of martial arts cultivation, it is fundamentally impossible to refine the Semi-Saint True Liquid.

  "Thank you, Master. With your guidance, I'm sure my cultivation will reach new heights." Kong Xuan was overjoyed and bowed to Zhang Ruochen once again.

  Kong Xuan and Zhang Ruochen immediately began their closed-door training, one to refine the Semi-Saint True Liquid and the other to consolidate his realm.

  Liu Chuanshen provided a secret room for Zhang Ruochen, that secret room was usually Liu Chuanshens retreat.

  Once the secret room is closed, it can only be opened from the inside, and outsiders cannot break in.

  Kong Xuanpan sat in the center of the secret room and, under Zhang Ruochen's guidance, swallowed a drop of Half Sacred True Liquid.

  The power of the Semi-Holy Elixir was like a surge of extreme cold air, pouring into her body and instantly freezing it stiff, with a thin layer of ice crystals forming on the surface of her skin.

  Just as Kong Xuan's consciousness was becoming increasingly blurred, a warm current surged out from behind her back, entering her meridians, blood vessels, and qi pools, helping her to refine the holy power of the Half-Saint True Liquid.

  Kong Xuan immediately followed the method on the Peacock Sacred Canon, operating his true energy and putting all his energy into refining the Half-Saint True Liquid.

  Zhang Ruochen sat behind Kong Xuan, his finger pointing at the Tian Xin pulse on Kong Xuan's back. True energy continuously flowed out from his fingertips, like transforming into strands of crimson flames, following the Tian Xin pulse and surging into Kong Xuan's body.

  Gradually, Kong Xuan was able to independently manipulate the semi-sacred true liquid's sacred power, and began to autonomously refine the sacred power. A faint layer of cyan light appeared on the surface of his body.

  "Natural talent isn't bad." Zhang Ruochen withdrew his fingers and stared at Kong Xuan, nodding slightly.

  Then Zhang Ruochen retreated to one side, no longer paying attention to Kong Xuan, and began to cultivate the Nine Heavens Ming Emperor Scripture.

  He has successfully cultivated the second layer "Tai Ming Yu Jing Tian" of the Jiǔ Tiān Míng Dì Jīng, and can now begin to cultivate the third layer "Tai Qing Ling Huǒ Tiān".

  The third layer of Jiutian Mingdi Jing is not only about Gongfa but also has a kind of spiritual connection called "True Qi Linghuo".

  That is to say, as long as you reach the third layer of Jiutian Mingdi Jing, the true energy in your body will be like flames, and it will be called "Linghuo".

  Soul fire, and it's faster and more terrifying than ordinary flames, can present various changes.

  Zhang Ruochen sat cross-legged in the cultivation chamber, his hands clasped together, and the true energy from his palms surged out, naturally forming a flame-like shape.

  Flames spread from her fingertips, wrapping around Zhang Ruoxi's arm, shoulder, and chest, finally engulfing Zhang Ruoxi's entire body in flames.

  It was strange that the flames seemed to have no temperature, and even Zhang Ruochen's clothes were not burned.

  As he cultivated the third layer of the Nine Heavens Ming Emperor Scripture, Zhang Ruochen's cultivation steadily improved, and the Jade Pure True Qi within his body transformed into Spiritual Fire True Qi.

  Before long, a month's time had passed. Zhang Ruochen's boundary was completely consolidated, and the true energy in his body burned like flames forever.

  The air sea of the eyebrows is like a huge furnace.

  As long as Zhang Ruochen fully mobilized the true energy inside his body, a flame-shaped mark would appear on his brow, bursting out with scorching energy.

  "Cultivating to the third layer of Taiqing Spiritual Fire Heaven in the Jiutian Mingdi Scripture, his true energy finally underwent a qualitative change." Zhang Ruochen felt his entire body filled with power, and he was extremely delighted in his heart. He had finally become a strong martial artist.

  With Zhang Ruochen's help, Kong Xuan refined all four and a half drops of Sacred True Liquid, and her realm indeed took a big step forward. Now, her strongest explosive power reached eighty-eight oxen strength.

  Although it did not reach Zhang Ruochen's expected ninety cattle power, it was already quite impressive.

  Even Zhang Tianguai, the number one genius of Tianmo Ridge's thirty-six counties and states, was not as powerful as her when he was at his peak in Huangji.

  When Zhang Ruochen left the pass, Kong Xuan finally opened up the Qi Lake and broke through to the early stage of the Mysterious Extreme Realm.

  Zhang Ruochen brought KONG Xuan, who had broken through the boundary, to the Nei Gong Academy, and arrived at the cultivation secret mansion that Huang Yanchen had exchanged for him.

  Take out the key and open the cultivation secret mansion.

  This cultivation mansion is very spacious, with a martial arts training ground, a library, a bedroom, and even a garden for planting spiritual medicine, as well as a beast house specifically used to feed the fierce beasts.

  "To exchange for this cultivation secret mansion, it's probably not that simple with just a hundred merit points." Zhang Ruochen walked into the cultivation secret mansion and was also slightly shocked, feeling unbelievable.

  This cultivation mansion is much larger than the cultivation mansions of Duanmu Xingling and Chen Xi'er, it doesn't seem like a residence for students at all.

  Zhang Ruo Chen did not know that Huang Yan Chen had indeed spent 100 points of merit value to exchange for a cultivation secret mansion, but because of a sentence from the Silver Robe Elder's Hall Master, this secret mansion was expanded tenfold within a month, and it could completely compare with the cultivation secret mansion of a Silver Robe Elder.

  This is the treatment that only top students can enjoy.

  Kong Xuan was also shocked by Zhang Ruochen's cultivation secret mansion, saying: "Master, this one cultivation secret mansion is worth at least several hundred thousand silver coins."

  "I'm also not quite clear what's going on, I'll go ask Huang Shi Jie myself later."

  Zhang Ruochen stared at Kong Xuan and said, "From now on, you'll help me handle all matters related to the cultivation of the secret mansion. If you need maids or servants, just let me know."

  "Thank you for your trust, Master." Kong Xuan said.

  It's quite fortunate to be able to live in the inner palace academy, the dense spiritual energy within the academy and its safe environment are not something that can be compared to the outside.

  After making all the arrangements, Zhang Ruochen headed towards Huang Yanchen's cultivation secret mansion. Since the two secret mansions were very close to each other, it only took a moment for Zhang Ruochen to arrive at the outside of the cultivation secret mansion.

  But after Zhang Ruochen knocked on the door, no one opened it, and there didn't seem to be even a single maid in the cultivation mansion.

  "Could it be that Huang Shijie really accepted the task from Wuxi Academy and went to Yunwu County to hunt down the black market and the evil cult of Baiyue?"

  After Zhang Ruochen left Huang Yanchen's cultivation secret mansion, he went to Duanmuxingling's cultivation secret mansion. The one who opened the door was Xiao Hei.

  Xiao Hei walked on two legs, with a bamboo scroll clutched in one of his paws. He stared at Zhang Ruochen and said, "Zhang Ruochen, you've come to find Duanmu Yaotou."

  Zhang Ruochen looked at Xiao Hei's even plumper physique and smiled: "Is Duanmu Shijie not in the secret mansion for cultivation?"

  Xiao Hei shook his head and said, "A month ago, she left the Wushi Academy to go on a mission in Yunwu County. She hasn't returned yet. I thought you had also gone back to Yunwu County for your mission. Why didn't you go?"

  Zhang Ruochen shook his head and revealed a thoughtful expression. "Is it true that many students from the Wushang Academy have gone to Yunwu Commandery?"

  Xiao: "It's said that 90% of the students in the Imperial Academy have gone to Yunwu Commandery, even many outer sect disciples of the Four Great Institutes have rushed over. Everyone wants to earn merit points. Duanmu Yaotou originally didn't plan on going to Yunwu Commandery, but after receiving a letter, she also rushed to Yunwu Commandery."

  "This time, Wu City's Qianzhuang and Heishi are at war with the Baiyue Demon Sect, it is indeed a good opportunity to gain merit points."

  Xiao Hei continued, "I also heard another thing, it's said that you're valued by the Long Lao Ge and will be specially cultivated. Although you've just broken through to the Di Ji boundary, you can already enjoy the treatment of a Di Bang student."

  "How could I have known about this?" Zhang Ruochen was slightly surprised.

  Zhang Ruochen immediately thought of his own luxurious cultivation mansion. Could that also be the treatment for students on the Earth Ranking?

  Xiao: "The entire Wu City Academy should know about this by now. Many people say it's because of the Yun Chenxi's influence that you're receiving such treatment. Some even say it's because you've got connections with Chen Xi'er, so the higher-ups in the academy are giving you special attention. Luckily, those students all went to Yunwu Commandery, otherwise there would definitely be many people who wouldn't accept this and challenge you."

  Zhang Ruochen smiled indifferently and said, "Since we can enjoy the treatment of a top student, I should be able to receive a considerable amount of cultivation resources every month."

  Ordinary inner palace disciples can receive one and a half drops of sacred true liquid per month, which allows them to enter the first layer of the Book Pavilion and freely browse the martial skills and techniques inside.

  The treatment of students on the list is definitely better.

  Xiao: "Zhang Ruochen, what are your plans next?"

  "First, go and collect the cultivation resources. Then I plan to return to Yunwu County for a trip. I want to see what kind of powerful masters are in the black market and the Baiyue Demon Sect." Zhang Ruochen's eyes narrowed, and a sharp aura emanated from his body.

  Having reached the extreme boundary, Zhang Ruochen also wanted to interact with more people, only in this way could he become even stronger.
