When Xu Qi 'an was in the Spirit Refinement Realm, his physique had reached the peak of the Spirit Refinement Realm, so he had excellent cold resistance.
In Da Feng Da Geng Ren, there were specific requirements and processes for the advancement of the martial arts system. When one advanced from the Qi Refinement Realm to the Spirit Refinement Realm, the Qi, Spirit, and Spirit would become one at the peak of the Qi Refinement Realm. When Qi filled the upper, middle, and lower dantian, one's spiritual power would skyrocket. At this time, it meant that one could visualize and prepare to break through to the Spirit Refinement Realm. On the other hand, Soul Refinement Realm martial artists had keen intuition and super strong five senses. They had a strong early warning ability for danger and had vigorous spiritual power. They could radiate their surroundings, allowing the surrounding scenery to appear in their minds. They could also recall the sealed memories of the past and could use primordial spirit transmission. After reaching the peak of the Soul Refinement Realm, one's blood essence and primordial spirit would fuse together. At this time, one's physique would welcome a complete transformation. Furthermore, the Soul Refinement Realm was divided into low-grade and high-grade. Ordinary martial artists who cultivated the Soul would only be able to explore the limits of the Soul Refinement Realm. This was the low-grade. Those who continuously broke through the limits in a desperate situation were the high-grade. The more solid the foundation they laid during the Soul Refinement Realm, the deeper their foundation after the Dao Integration Realm would be. The more confident they would be in advancing to Rank-1 perfection. However, the article did not mention the special circumstances of Xu Qi 'an advancing to the Spirit Ascension Realm. According to the logic of the general martial arts system, if Xu Qi' an wanted to advance to the Spirit Ascension Realm, he had to meet the transition requirements from the Qi Refinement Realm to the Spirit Ascension Realm.

When Xu Qi 'an was in the Spirit Refinement Realm, his physique had reached the peak of the Spirit Refinement Realm, and he was extremely cold resistant. However, the original text did not mention the other special things that the Spirit Refinement Realm could do.
In the Da Feng night watchman, the eighth grade martial artist, Qi Refinement, could open the heavenly gate and receive the spiritual power of heaven and earth into the body. It could interact with heaven and earth, produce qi movement, practice qi sense, and increase one's strength to fly over roofs and walk on walls. The release of qi could transfer qi to others. This was a magical ability of the early stage of the Qi Refinement Realm. When one held a sword, they could activate saber qi or sword qi. A cultivator at the peak of the Qi Refinement Realm could cut through walls with a single strike and control objects from afar. The three were one. When Qi filled the three dantians, one could prepare to break through to the Spirit Refinement Realm. Moreover, Qi was exclusive to martial artists. At the middle and low ranks, only martial artists could use it. At the high ranks, although other systems could be used, they were far inferior to martial artists.
After Xu Qi 'an broke through to the Spirit Refinement Realm in prison, Xu Xinnian went to the Eldest Princess for help with the Earth Book. Mountain River Temple exploded, broke his hand and escaped, parasitizing Heng Hui. Emperor Yuanjing ordered Wei Yuan to investigate the explosion on the 15th, and Chu Yuanzhen appeared. He was the Imperial Advisor's disciple, and the Imperial Advisor was in seclusion at the time. Under the persuasion of Lin An and the Crown Prince, Emperor Yuan Jing let Xu Qi 'an investigate the case and atone for his crimes.
Song Tingfeng came to find Xu Qi 'an, and then they went to raid the Taikang County Magistrate's house. Because the Taikang County Magistrate had violated the law and bullied women, Xu Qi' an killed Zhu Yinluo in anger. Zhu Jinluo wanted to kill Xu Qi 'an but was stopped by Yang Yan. Wei Yuan announced that Zhu Yinluo was dismissed from his post and Xu Qi' an was cut in half seven days later.
The safest and most convenient method in the world was still to use a medicinal bath and invite a Soul Refinement Realm expert to open the Heavenly Gate for him.
For a martial artist in the Spirit Refinement Realm to advance to the Qi Refinement Realm, there were two methods that were eliminated: the breathing method, which cost a lot of money, and the Demon Swallowing Pill, which was extremely risky.
Together with the medicinal bath, he would then invite a Spirit Refinement Realm expert to open the Heavenly Gate for him.
In Xu Yang's novel "Refined Qi for 100,000 Years", the realms were divided as follows: Beginner level (early stage of Refined Qi), Spirit Concentration level (middle stage of Refined Qi), Foundation Establishment level (late stage of Refined Qi), Core Formation level (great perfection of Refined Qi), Nascent Soul level (Void Refined Dao Integration), Soul Separation level (late stage of Nascent Soul), and Mahayana level (Dujie stage). As for Xu Yang's specific realm, the search results did not provide clear information, so it was impossible to give an accurate answer.
In the novel,'Refined Qi for 100,000 Years', Xu Yang was the ancestor of Sky Mist Sect and had trained for 100,000 years. Even though his realm had stagnated, he had accumulated a hundred thousand years of cultivation, so his strength was extraordinary. According to the first document, the realms of Qi Refinement for 100,000 years were divided into the entry level, Spirit Concentration level, Foundation Establishment level, Core Formation level, Nascent Soul level, Soul Separation level, Mahayana level, and Tribulation Transcendence level. According to the fourth document, Xu Yang had successfully broken through to the Foundation Establishment Realm and became the most powerful existence in the human world. Combining this information, one could conclude that Xu Yang's realm was the Mahayana realm.
