As she took over the cyan wooden box, Zhang Ruochen could feel a faint coolness on its surface.

  It's not the wooden box that's cool, but the medicinal dan in the wooden box that emits a cold air.

  Zhang Ruochen opened the cyan wooden box, and a strong fragrance of cinnabar wafted out. Strands of white cinnabar energy, like small snakes, flew out of the box and circled around it.

  Zhang Ruochen saw the eight elixirs in the box and his eyes lit up with a strange color, saying: "Ice Pulse Pill."

  "You know this kind of Dan medicine?" Little Hei was somewhat surprised.

  "In the medieval period, this Dan medicine was very popular, but later it was monopolized by various top forces and could hardly be bought on the market. I didn't expect you to be able to refine this kind of Dan medicine."

  In the medieval period, many human warriors used elixirs to temper their meridians, increasing their flexibility and enhancing the circulation speed of true energy, even allowing their meridians to produce certain attributes.

  Bing Mai Dan, Huo Mai Dan, Dian Mai Dan and Feng Mai Dan were all researched during that period and widely spread among martial artists.

  Taking the Ice Pulse Pill not only refines the meridians, but also gives them an icy attribute. Once the true energy is circulated, the body can transform into an icy physique, and a single palm strike can freeze mountains and rivers.

  After taking the Huo Mai Dan, one can make their meridians produce flame attributes, spitting out flames with just a mouthful and condensing fireballs with just a raise of their hand. Some formidable warriors can even use their true energy to condense flame wings, soaring through the sky.

  If Zhang Ruochen became an inner disciple of the Wumeng Xuegong, he would naturally be able to use his merit points to exchange for Bingmou Dan. However, as an outer disciple, even if he had merit points, there were many things that he couldn't exchange for.

  Now that Xiao Hei has refined the Ice Pulse Pill, it's as if he's helped Zhang Ruochen a great deal.

  "Bing Mai Dan is suitable for martial artists with a cold and icy physique, while my true energy carries a hint of thunder and space power. If you can refine the Electric Pulse Pill, it will be of even greater help to me." Zhang Ruochen closed the cyan wooden box and put it away.

  Although Bingmo Dan is not as suitable for Zhang Ruochen as Dianmo Dan, it still has a huge help for Zhang Ruochen.

  "Electric Pulse Dan is okay"

  Xiao Hei's expression turned contemplative, as if recalling the formula for the Electric Pulse Dan.

  Zhang Ruochen didn't rush to refine the Ice Marrow Dan, after all tomorrow he would be leaving the palace and returning to Wu City's Xue Palace, so tonight was naturally a time for him to spend with Lin Fei.

  Yu Xiu Palace, where Consort Lin resides.

  "Mother, come with me to Wushi Academy. I'm worried about leaving you alone in the palace," Zhang Ruochen said.

  Lin Fei lightly pursed her lips, staring at Zhang Ruochen who had grown a bit taller, shook her head and said: "Dust, don't worry, Mother is just an ordinary person. Although the Queen dislikes me very much, she won't really harm me. Living here for almost twenty years, Mother doesn't want to leave anymore."

  Zhang Ruochen let out a soft sigh and said, "You still can't bear to part with Da Wang"

  "He is your father king." Lin Fei said.

  Lin Fei and Yun Wu County King indeed have feelings for each other. If she were to be taken away by Zhang Ruo Chen to the Wushu Academy, how would outsiders view Yun Wu County King?

  "Alright, I respect Mother's choice."

  Then, Zhang Ruochen took out three jade bottles and a package containing silver coins and spiritual crystals, handing them to Lin Fei, "Mother, the three jade bottles contain 300 Blood Dans, all of which are first-rate Blood Dans that you can fully absorb. As long as you persist in taking the Blood Dans, your physique may not be comparable to that of a martial artist, but it will definitely be much stronger than that of an ordinary person."

  "Additionally, inside the bundle were five hundred silver coins and twenty spirit crystals."

  Originally, Zhang Ruochen could have left more silver coins and elixirs behind, but after some thought, he decided to leave the excessive silver coins and elixirs for Lin Fei, which might not necessarily be a good thing.

  Huang Yanchen, who was standing beside him, walked to Lin Fei's front and handed over the phoenix-shaped crimson jade worn on his neck. He said softly: "Auntie, this piece of fire cloud jade has three defensive powers. If you are attacked, it can help you block three dangers. Moreover, wearing it for a long time can strengthen your physique and calm your mind."

  If someone else had given such a precious gift, Lin Fei would have definitely not accepted it. However, since it was her own son's fiancée Song's gift, Lin Fei naturally received it with great delight.

  Leaving Lin Fei's residence and walking out, Zhang Ruochen suddenly stopped in his tracks, stared at Huang Yanchen and said: "Master sister, what do you mean exactly?"

  Huang Yanzhen stood not far away, and restored his cold and proud appearance, raising his snow-white chin, saying: "It was just a piece of jade that was sent, what's the big deal? Zhang Ruochen, there is one thing I must make clear to you. My engagement with you was only because it couldn't be helped. When we return to Wu Shi Xue Gong, you absolutely cannot mention this to anyone. If I find out that a third person knows, I will definitely not forgive you."

  Zhang Ruochen said: "The news of our engagement has long been spread throughout the various countries and must have already reached the Wu City Academy."

  Huang Yanchen said: "Even if the news has been sent back to Wushu Academy, you must deny it with a straight face. Besides, we are only engaged now and there are still three years before we get married. You should understand that we can't really get married. Three years later, we will divorce together, what do you think?"

  "I have no opinion," Zhang Ruochen said.

  When Zhang Ruochen said that so decisively, Huang Yanchen didn't know why, but instead felt a little angry and said in a low voice: "I hope you won't regret the promise you made today three years later."

  The next day, Zhang Ruochen, Huang Yanchen and Zhang Shaochu set out on their journey back to the Wu City Academy.

  Zhang Shao was nervous all the way, following at the back, and didn't dare to walk in front of Huang Yanchen.

  Zhang Shaochu also stayed in the Wucheng Academy for more than a year, and Huang Yanchen's name was simply like thunder to his ears. Any male student who heard her name would be frightened with a drastic change in complexion.

  The title of the three great female demons is not just for show.

  But now, Huang Yanchen has become Jiu Di's fiancée, and Zhang Shaochu's mood is quite complicated, with a mix of happiness and fear.

  Fortunately, from now on in the Western Courtyard, he can finally hold his head high and who dares to bully him again.

  What's scary is that Huang Yanchen is so powerful, can Jiu Nian suppress her?

  When they returned to the Western Academy, it was already three days later, and only half a month remained before the Intermediate Ruins Exploration Exam.

  Back to the Western Courtyard, Zhang Ruochen went to visit Duanmu Xingling, but it turned out that Duanmu Xingling was not in the No. 1 room of the Mystic Department. A thin layer of dust covered the desk, as if he had left for a long time.

  Before the intermediate relic exploration exam, she would definitely rush back, so Zhang Ruochen didn't think much about it.

  Back at Huangzi First Number, Zhang Ruochen directly entered the interior space of the Time and Space Crystal, taking out the cyan wooden box containing the Ice Pulse Pill.

  In the box were eight Ice Pulse Pills, each one a fourth-grade medicinal pill, emitting a chilling aura.

  Zhang Ruochen's fingers had just touched the Ice Marrow Dan when they were frozen in place, covered by a thin layer of frost that encased his entire hand.

  "It's indeed a high-quality medicine, very potent."

  It's imaginable that even if Zhang Wuji is now only at the level of a Yellow Extreme Boundary cultivator, let alone refining and transforming the Ice Marrow Dan, he would probably be frozen solid by the cold energy just from touching the dan.

  Zhang Ruochen manipulated his true energy, and it flowed through his meridians, surging towards his five fingers.

  With a crack, the ice in his hand shattered.

  Under the wrapping of true energy, Zhang Ruochen picked up one of the Ice Pulse Pills and took it into his mouth, swallowing it into his abdomen.

  A cold Dan Qi burst open in the abdomen, and after a moment, a sharp pain came from the abdomen, as if all five organs were frozen by the Dan Qi.

  That chill was extremely strong, ten times colder than when Zhang Ruochen first took the Half Sacred True Liquid.

  If a warrior from another Extreme Realm were to take the Ice Vein Pill, they would absolutely be seeking death, and would instantly be frozen to death by the explosive energy of the pill.

  Zhang Ruochen, although also a cultivation base in the Mystic Extreme Realm's extreme position, has a physical body that far surpasses that of martial artists of the same realm. Moreover, he cultivated the Supreme Extreme Realm at the Yellow Extreme Realm, summoning the resonance of all gods.

  That time when all the gods resonated, to a certain extent, transformed Zhang Ruochen's meridians and Qi Lake, barely able to withstand the icy air of Bing Mai Dan.

  "Hehe"

  Zhang Ruochen activated all 36 meridians, allowing them to operate at the fastest speed, refining and transforming the Dan Qi of the Bing Mai Dan.

  Ten days later, Zhang Ruochen fully refined the medicinal properties of the Ice Marrow Pill and his body gradually returned to normal temperature. However, his muscles and meridians were still very stiff.

  Zhang Ruochen opened his eyes and spat out a mouthful of white air.

  "My body feels so heavy, it's hard to even move my fingers." Zhang Ruochen was like a person who had been frozen in ice for ten thousand years and had just awakened, his whole body numb, feeling extremely heavy, and every movement would cause severe stabbing pain.

  Zhang Ruochen struggled to get up, and began to slowly practice his palm technique.

  Through the practice of Qigong, cold energy is refined into the meridians and bones, thereby strengthening the constitution.

  From now on, if other warriors use ice attribute martial skills to attack Zhang Ruochen, Zhang Ruochen can also more easily resist.

  Time and time again, he struck out with dragon elephant-like palms. Zhang Ruochen only felt his strength growing stronger and stronger, the speed of his palm strikes also getting faster and faster.

  The speed of the flow of true Qi in the meridians has also accelerated by about 30% compared to before.

  The faster the flow of true energy, the stronger the power that bursts out naturally.

  In the inner space of the Time-Space Crystal, Zhang Ruochen practiced his palm technique for five consecutive days, each time exhausting his internal Qi before stopping. After stopping, he took medicinal pills to recover his Qi.

  In five days, Zhang Ruochen completely refined the remaining Ice Marrow Dan's dan energy into his body, and his martial arts realm reached the peak of the Extreme Boundary in the Mystic Realm.

  The true energy in the air lake has been fully cultivated and can break through to the extreme boundary of the great pole at any time.

  In the Time-Space Crystal, he had been cultivating for fifteen days, but outside, only five days had passed. Zhang Ruochen still had enough time to impact the boundary.

  "Zhang Ruochen, Duanmu Xingling has arrived. The first yellow character number one, I told her you are in seclusion. Do you see her or not?" Little Hei's voice sounded within the space-time crystal.

  "Duanmu Shijie is back, she must have brought some news, of course I want to see her." Zhang Ruochen's face showed a joyful expression, he still had a good impression of Duanmu Xingling.

  Suddenly, he thought of something else.

  Having been with Endo-senpai for so long, yet I still haven't asked her which country's warrior she is from.

  Apart from knowing she was an outer palace disciple of Wushang Academy, everything else about her was a complete blank.
