When the Four Spirits Seal was taken off, the formation in the underground palace changed, and the Yin Qi of the Earthly Demons that had been accumulated in the Underground Palace for hundreds of years rushed out to seal the Underground Palace. Originally, Gu Xiancheng should have transformed into the Underground Palace formation to seal all the Yin Qi of the Earthly Demons in the Underground Palace, but Gu Xiancheng was injured by his Yin God stick, causing the formation power of the Underground Palace formation to appear and some Yin Qi of the Earthly Demons were leaked. For some reason, these Yin Qi of the Earthly Demons were absorbed by Zhou Zhenglin's alchemy furnace and integrated into the Shangqing Yuqi Pill in the tempering of the Dan Fire, thereby increasing the elixir of the Shangqing Yuqi Pill by several levels.

Xu Changqing stepped forward and pushed open the door of the alchemy room. A yin and cold air rushed out of the alchemy room. The temperature in the alchemy room seemed to have entered the severe winter, and the surrounding walls had already formed a layer of ice slag. Among the people in the alchemy room, the Huang brothers and sisters were people who practice Taoism after all, and the three yang true fire in their bodies was extremely strong. This little cold would not affect them. However, Zhou Zhenglin, an ordinary person, could not leave the alchemy room because he had to observe the heat from time to time. His clothes were also thin, and his whole body was frozen white and purple.

After seeing Xu Changqing, everyone was about to get up to greet him, but Xu Changqing signaled that everyone did not have to get up. After that, he walked to Zhou Zhenglin and distributed a stream of golden elixir true energy, which penetrated from Zhou Zhenglin's heavenly spirit to dispel the cold and cold energy in his body. After Zhou Zhenglin shivered for several times, his face gradually returned to normal. He let out a long sigh, stood up to greet Xu Changqing, and said, "Thank you, Mr., for helping him!"

Xu Changqing raised his hand calmly and said, "Young Master Zhou, don't be polite. This is why I am not considering it carefully, so I will make you suffer. I hope you don't blame me."

After the two of them were polite, Xu Changqing signaled Zhou Zhenglin not to move, and then walked to the alchemy furnace, cast the spell to open the magic sky eye, and observe the heat of the alchemy. At the moment, the fire under the alchemy furnace was burning vigorously, but the alchemy furnace was always as cold as ice. And if the fire was stopped, the fire would inevitably be extinguished by the cold air in the alchemy furnace.

Xu Changqing knew that the Shangqing Yuqi Pill was no longer able to be refined by this kind of mortal fire, so he told everyone not to add firewood and signaled them to retreat to Zhou Zhenglin. Although everyone did not understand what he meant, they still followed his instructions to retreat from the alchemy furnace. Just when the flames under the alchemy furnace were extinguished by the cold air in the alchemy furnace, Xu Changqing, who had already sat cross-legged by the alchemy furnace, displayed all the Samadhi True Fire in his body, and was surrounded by a bright red flame. Then he continued to form magic seals with his hands, and the three true fires filled with the power of the upper clearance were shot into the alchemy furnace to replace the alchemy fire to temper the alchemy medicine.

When Chen Yuanshan and others saw Xu Changqing's body surrounded by golden flames, they showed a divine power and sighed with envy, while the Huang brothers and sisters looked proud, as if the Samadhi True Fire was refined by them.

This is the first time Xu Changqing uses Samadhi True Fire to temper elixirs. His mind is extremely focused. At the same time, he also takes this opportunity to consolidate the cultivation level of the Tao that he has just improved. Xu Changqing's Samadhi True Fire is very unique. Unlike ordinary Samadhi True Fire that has the domineering ability to melt all things, its flame is extremely gentle, and no matter how strong the firepower is, it only has the skill of tempering, which is extremely suitable for refining elixirs.

Thanks to Xu Changqing's addition, the extremely ordinary practice pill, the Shangqing Yuqi Pill, has been upgraded to another level. Xu Changqing has been completely immersed in the alchemy at this moment. The heart of Tao was unknowingly integrated with the great way of heaven and earth. The Shangqing Dharma Seal, whose hands are constantly changing, gradually changed from deliberate use to the spontaneous movement that conforms to the great way. In Xu Changqing's constantly changing handprints, the secret of the great way is hidden. Among the few people who have been watching him, Huang Juan, who has lost all the eyes of heaven, immediately felt the power of the great way in his handprints, and involuntarily sat down, took its qi to pull it, and evolved together.

Immediately afterwards, Huang Shan, who was wise and Chen Yuanshan, who was extremely talented, also vaguely noticed the power of the great way in Xu Changqing's handprints, and sat down cross-legged. Under the guidance of Xu Changqing's aura, he changed his handprints and realized the great way. Zhou Zhenglin was just an ordinary person, while Zhou Qinglan was not qualified enough to feel anything strange from it. However, Zhou Qinglan, who was half a practitioner, knew that the few people in front of him had entered a state of mind that he didn't know, so he pulled Zhou Zhenglin aside and looked at them quietly, his eyes full of envy.

At present, the four people have their own understanding of the great way, and the seals formed by the power of the great way are also different. Xu Changqing's seals are unpredictable, and their movements are like flowing clouds and water, which makes people feel extremely calm. Huang Juan's seals are numerous and complex, and they feel like they are shrouded in fog. Huangshan's seals are simple and slow, as steady as mountains, while Chen Yuanshan's seals are single and unchanged, with a hint of simplicity of the great way.

Under the leadership of Xu Changqing, the four of them felt their own way. After two days, Chen Yuanshan first woke up from the insights of the way. From his happy face, he could know that he had gained a lot. Half a day later, Huang Shan and Huang Juan also separated from the insights of the way. Although Huang Shan still seemed innocent on the surface, a hint of agile light flashed in his eyes, while Huang Juan changed even more. Her whole body seemed to be shrouded in a layer of fog, which made people feel a strange feeling that he was so close to the world. Moreover, a congenital Bagua diagram appeared in the eyes that were always empty.

As Xu Changqing felt the deep understanding of the Dao, the Samadhi True Fire that had not weakened on his body also changed a little, and the color gradually went from bright red to golden yellow. When all the Samadhi True Fire turned golden, Xu Changqing only heard five thunderous sounds, and at the same time, the back of his head seemed to be cracked. The five elements of the body arose from behind his head, forming five balls of different colors, Yin Shenshuo Banner, Soul-Swinging Bell, Dao Diagram, and the clone phantoms of five magical objects of Dingtian Hunyuan Pearl were also looming in the ball. These five balls were all wrapped in Samadhi True Fire, and they kept rotating around the back of his head in a wheel-shaped trajectory of the five elements.

"Five Qis are coming to the Yuan Dynasty! These are the Five Qises coming to the Yuan Dynasty!" Chen Yuanshan looked at Xu Changqing's changes excitedly and couldn't help but scream softly.
