Su Dao Xing returned to his residence and immediately took out the Huo Ling Stone, starting to absorb the fire spirit power within it thread by thread, refining it into his own spiritual energy. The energy flowed through the meridians in his body again and again, finally entering the Qi Hai, forming a spiritual aura.

  Spirit energy is divided into nine grades, with each grade being stronger than the previous one. Currently, Su Dao Xing's spiritual energy in his dantian is still of the first grade. Once he has stored enough first-grade spiritual energy in his dantian, he will then transform the first-grade spiritual energy in his dantian into second-grade spiritual energy.

  Su Dao Xing currently possesses a large amount of Huo Ling Shi, which is enough for him to refine and fill his Qi Hai with first-rate spiritual energy.

  Knock knock!

  A knock at the door.

  Su Dao Xing guessed it was Wen Hongmei knocking on the door. He couldn't afford to develop a bad habit of relying on others when he needed them and ignoring them when he didn't, even though he wanted to continue refining the fire spirit power within the Fire Spirit Stone without any distractions.

  Wen Hongmei waved three letters of challenge in front of Su Dao, saying: "These are the three letters of challenge to you. How will you deal with them?"

  Avoiding battle is a cowardly act, and will be despised by classmates. The Holy Institute will also punish students who avoid battles. Su Dao Xing would not avoid battle, he thought for a moment, then said: "Within seven days, anyone who comes to challenge me, let them go to the Medical Department's Martial Arts Arena on the morning of the seventh day, I will appear at that time."

  "You plan on one against many?" Wen Hongmei guessed Su Daowei's intention.

  "One by one is a waste of time, I don't have time to waste on this. Let them come together later, I've recently learned two new skills, just in time to use them." Su Dao Xing's face showed a hint of impatience, since he entered the Abyssal Realm and experienced those things, he had undergone some changes, he was racing against time to get stronger, unwilling to waste any time on other things.

  "Arrogant!" Wen Hongmei also felt that Su Daowei was too arrogant, "But you have the capital to be arrogant. I'll do as you say. Hope that day you won't disappoint anyone, after all, you are now the representative of the medical hall, if you lose, it means the medical hall loses, and the Art Saint Institute loses."

  "Don't use that trick on me again." Su Dao Xing was slightly displeased, saw off Wen Hongmei and immediately closed the door, continuing to cultivate in another courtyard.

  Su Dao Xing began to temper his spiritual sea with the soul power in the soul pool within the sea of consciousness, and started to refine his physical body with spiritual energy.

  Although the Grandmaster can cultivate his soul after entering the realm of cultivation, and even separate his soul from his body, the cultivator mainly cultivates his soul. However, with a strong physical body as a carrier, it is possible to nourish an even stronger soul. Once the physical body deteriorates, it is also difficult to cultivate a very strong soul.

  The physical body is the foundation and the root. Su Dao Xing decided to first build a solid foundation before breaking through to become a powerful cultivator in the realm of cultivation, stepping into another world of practice.

  Su Dao Xing found a body-refining technique from the legacy of the Demon Saint, which was also an ancient demon tribe's body-refining technique. It wasn't created by the Demon Saint itself, but rather modified by it. Humans can also cultivate this technique.

  The Body Refining Technique is divided into seven levels: White Body, Blue Body, Purple Body, Copper Body, Silver Body, Golden Body, and True Body.

  The method of refining the body by the Demon Saint is extremely abstruse, and even ordinary masters can't fully comprehend it. Su Dao Xing has inherited the experience of the Demon Saint's cultivation of this method, so naturally he doesn't have too much difficulty in cultivating it.

  The method of refining the body requires a large amount of spiritual energy to drive it, and accumulating a large amount of spiritual energy is a very difficult thing for both the sect master and the cultivator. However, Su Dao Xing can use the Temple of Heaven, Buddhist temple, and Demon temple to continuously provide heavenly and earthly spiritual energy, making it easy to accumulate a large amount of spiritual energy.

  Crack crack!

  Su Dao Xing Yun Zhuan Lian Ti Zhi Fa, guides the spiritual energy to refine the spiritual meridians, acupoints, and refines every inch of bone, every blood vessel, every joint, refines the five organs and six viscera, skull, skin, flesh, and tendons.

  In just one day's time, Su Daochen had already refined his body into a white body, with his entire body as clean and pure as jade, emitting a faint white aura.

  "The first realm of the White Body is the first boundary of the Demon Saint Refining Body, I didn't expect that my physical defense has increased by more than tenfold." Su Dao Xing was extremely satisfied and couldn't wait to continue tempering his body.

  In five days, Su Daoxian spent a great deal of energy and a vast amount of spiritual energy to refine his body into a blue one. His entire body was a bright blue, even the air he breathed out and the phlegm he spat out were all blue.

  "The Double Blue Body of the Refining Body has been successfully cultivated, and the defense of the flesh has increased by more than a hundredfold." Su Dao Xing was shocked, he did not expect the Refining Body technique of the Demon Saint to be so miraculous.

  Time flies when cultivating, Su Dao Xing only felt that in the blink of an eye, it was already the time he had agreed to meet and challenge the challenger. He walked out of his residence and headed towards the medical hall's martial arts arena.

  All the way, the students saw Su Dao Xing holding back their laughter, Su Dao Xing was really too funny, and had dyed his body blue.

  Su Daoming faced a series of strange gazes from his teachers and classmates, feeling embarrassed at first but getting used to it later.

  "Sudao Xing has woken up! Ah! Now I'm not sure if Sudao Xing has woken up."

  The students saw Blue Su Dao Xing appear on the martial stage and didn't dare confirm whether it was the real Su Dao Xing.

  The hundreds of people around the martial arts arena couldn't help but stifle their laughter at Su Dao Xing's appearance.

  "Laugh if you want to." Su Daowei smiled freely.

  "Haha!"

  "Hahaha!"

  For a moment, laughter shook the sky.

  Su Dao Xing's face was gloomy as he stepped onto the martial arts stage.

  On one side of the martial arts platform stood thirty masters in a neat square formation beside the platform.

  Wu Shengyuan's Lu Haiqing, Kong Yue, Tang Pinchao, Tang Dazhi, Tang Qian, and Tang Tianhe were all present.

  "Could it be that these thirty people are the ones ranked ahead in the Saint Name Registry of the Wu Sheng Institute?"

  "The top 100 ranking list, students from Wu Shengyuan can occupy thirty percent, worthy of being the first strong institute."

  "What does it mean for thirty masters from Wu Shengyuan to come and surround Su Dao Xing?"

  The students started discussing it in seven mouths and eight tongues.

  Su Dao Xing stood on the martial arts stage and said to the thirty masters of Wu Shengyuan: "I will fight one by one, please let the first person who comes out to challenge me come and have a battle."

  At this moment, most of the thirty masters looked ugly.

  If thirty masters came to challenge Su Dao Xing one by one, they wouldn't have come all at once with so many people, just to gang up on Su Dao Xing.

  Lu Hai's face sank, and he said: "Su Dao Xing. If you alone defeat our thirty-man formation, the Wu Sheng Institute is willing to take out the Wu Sheng Tang Xi's handwritten secret method for entering the true cultivation realm from the Bai Mai Zong Shi. If you lose, you will join the Wu Sheng Institute. How about it?"

  The cultivation experience of Wu Sheng Tang Xi has a fatal attraction to Su Dao Xing, who is about to enter the realm of refining truth. Currently, he is still half-understanding how to upgrade, and with the cultivation experience of Wu Sheng Tang Xi, he can avoid many detours.

  "Are you willing to accept the challenge?" Kong Yue glanced at Su Dao Xing.

  "Come on! All of you, come at me together!" Su Dao Xing's body emitted a powerful aura, with an attitude that completely disregarded the thirty masters of Wu Sheng Yuan.

  The update speed is the fastest, hurry up and come!
