An hour passed, and Ao Lingtian still couldn't condense his fighting spirit into a square space of his imagination.

"How did you not form a space?"

"That's right, Breath Formula!"

Ao Lingtian suddenly remembered to use the Breath Technique to operate, condense the Dou Qi to form a space, and immediately used the Breath Technique Technique.

As soon as the Breath Technique was activated, the Dou Qi in his body instantly formed the quadripartite space he imagined.

"Teacher, what should you do next after forming the space?" asked Ao Lingtian.

"You have formed a space for fighting qi?" the old man exclaimed, he didn't dare to imagine that Ao Ling Tian had condensed his fighting energy into a space in just a short period of time.

"Hmm!"

Ao Lingtian nodded with a faint smile.

"How did you do that?" said the phantom elder with a curious look on his face.

"I used the breath trick to operate, and as a result, a space was formed in an instant. "Ao Lingtian is also unclear.

"Breath formula?"

Hearing this, the phantom elder frowned slightly, looked at Ao Lingtian with his eyes, and said in a condensed voice: "Do you know how long it took me to form a fighting space back then?"

Ao Lingtian shook his head, he could see that the Phantom Elder seemed to be very surprised by his formation of a fighting space.

"That's it!"

The Phantom Elder stopped and said, "After you have formed a Dou Qi space, now start using Dou Qi to break through the container in your body that stores Dou Qi and connect them together!"

"Breaking through the connection?"

Ao Lingtian was surprised, because he knew that breaking through his own Dou Qi's memory would definitely damage his meridians and cause injury.

"That's right!" Phantom replied with a nod.

Ao Lingtian didn't ask any more questions, and at the moment, the Dou Qi hit the container where the Dou Qi was stored, and the first impact, the internal organs in his body were as painful as if they had been impacted.

"Poof!"

The first impact failed to break through, and the second impact broke through the container where the fighting qi was stored, but blood spurted out wildly.

When he broke through the container where the Dou Qi was stored, the Dou Qi in his body instantly and automatically connected to the Dou Qi to form a space.

"Are they connected?" Seeing Ao Lingtian vomiting blood, Phantom Old knew that he had broken through the container where the Dou Qi was stored.

Ao Lingtian endured the pain in his body and nodded in response to Phantom Elder.

"Boy, it's going to be very painful and uncomfortable, you have to hold on!" said the phantom elder seriously.

"Teacher, don't worry!" Ao Lingtian's eyes were full of unwavering expression.

"Refining gas is like fire, all things are refining and burning, gas is fire, and the world burns!" "Phantom Lao taught the formula of refining qi to Ao Lingtian.

"Refining gas into fire!"

Ao Lingtian understood the mantra taught by the Phantom Elder in the first sentence, refining qi like fire means refining qi into fire.

"How to refine gas into fire?"

Ao Ling Tian didn't comprehend how this Qi Refining Qi could become a flame at all!

"All things are refined!" When the Phantom Elder saw Ao Lingtian's brow, he immediately repeated the mantra of all things refining and burning.

"All things are refined and burned, and gas is fire, and qi is imagined as fire to be refined, and it becomes real fire?"

When Ao Lingtian was reminded by the Phantom Elder, he suddenly realized that the fighting energy in the four square spaces in his body was condensed, and the fighting energy instantly seemed to be tumbling and boiling.

"This is the time!"

Phantom Elder sensed any movement on Ao Ling Tian's body, and knew that the fighting qi in his body was boiling in his square space, and Phantom Old quickly recited something in his mouth.

However, as he recited the mantra, yellow runes appeared on his body, and these runes instantly submerged into Ao Lingtian's body.

"Ahh

Ao Lingtian's eyes suddenly opened, and he screamed loudly in severe pain, and the phantom old man immediately sounded the entire room with his fighting spirit, and no one in the Ao family heard Ao Lingtian's shouting.

"My body feels like it's being roasted by fire!"

Ao Lingtian's face was extremely distorted, his hands and fingers were clenched, he felt his body as hot as a sea of fire, and even the internal organs in his body were as uncomfortable and painful as scalding.

"Hold back!" Seeing this painful and uncomfortable appearance, Phantom Lao immediately shouted for him to resist.

However, it was as if a sea of fire had appeared in Ao Lingtian's body, burning all the organs in his body, and many meridians were burned and damaged.

"Breath Formula!"

Ao Lingtian's mouth was soaked with blood, and he felt that the internal organs in his body were about to be scorched, and he immediately used the breath technique, trying to protect the meridians and internal organs in his body.

"Poof!"

A mouthful of blood spurted out, and the operation of the breath technique had no effect in the slightest.

"The fire of refining qi, condense!"

The Phantom Elder let out a loud cry as he spat out yellow runes from his mouth, which exuded a powerful aura of power.

However, this time, the rune did not fly into Ao Lingtian's body, but instead swirled around him.

"Ahh

Ao Lingtian let out another painful scream, and black gas came out of his mouth and nose.

After a long time, Ao Lingtian felt that the burning sensation on his body was rapidly receding, and his face slowly calmed down.

"There seems to be a powerful flame in my body!" Ao Ling Tian felt a very powerful flame in his body.

"That's the space I just opened up, where is a flame?" Ao Ling Tian sensed that there was a faint flame in his body at this time, although it was faint, but Ao Ling Tian felt that its power was not ordinary.

"Teacher, there seems to be a flame in the body, is it a fire of qi refining?" Ao Ling Tian didn't know if this was the so-called fire of qi refining.

However, the Phantom Elder nodded and said, "That's right!"

"Teacher, didn't you say that it was difficult to refine into a Qi Refining Fire?" Ao Ling Tian felt that cultivating the Qi Refining Fire was very simple at this time, except for suffering a little pain.

"Stinky boy, don't be complacent, if it weren't for the teacher to help you directly condense into a Qi Refining Fire, I'm afraid you would have to cultivate for a long time now before you can truly refine into a Qi Refining Fire. Phantom Old Man scolded with a smile.

"It was the teacher who helped me condense into a Qi Refining Fire just now?" Ao Lingtian didn't know that it was the Phantom Elder who helped him just now, he was so painful and uncomfortable just now that he didn't know when the Phantom Elder helped him.

"The fire of refining qi is very difficult to cultivate, and it is a hundred times more difficult than cultivating one's own strength. "Elder Phantom knows how difficult the cultivation of Qi Refining Fire is.

"Teacher, I won't give up halfway!" said Ao Lingtian with a firm expression.

"The fire of refining qi is now possessed by many refiners, but it is difficult to say how powerful the fire of refining is. Phantom Lao said indifferently.

"I feel that my Qi Refining Fire at this time is very weak now!" said Ao Lingtian with a frown.

"The fire of qi refining is like it has just sprouted, and you have to keep giving it food in the middle to let it grow. Phantom Elder explained.

"I see!" nodded in understanding.

"Your refining gas is the source used to store the gas refining fire, if you want to release it, cut off the refining gas from the container where the gas refining itself stores the fighting gas, and the gas refining fire can come out. Phantom Elder informed.
