Because the Li family is an alchemist family, because they have a large team of alchemists, they can prepare so much spiritual liquid in a very short time. Including Li Feng, all of them entered a deep state of cultivation, absorbing the spiritual power in this medicine pool to the maximum extent and refining their bodies.

The spiritual liquid in the medicine pool was only aimed at the cultivator's physical body, and in less than ten breaths, many people who were soaked in the medicine pool felt that their bodies were slowly getting hotter. Some people's faces began to turn red, and some even had fine beads of sweat on their foreheads.

"Pour the beast's blood into it!" said the old man in the blue robe, faintly.

A smile appeared on the face of the golden-robed old man, and he said lightly, "How long do you say they can hold out?"

"Half an hour!" said the blue-robed old man with a smile. The other three also nodded slightly, agreeing with the blue-robed old man's statement.

As he spoke, the golden-robed elder turned over his hand and took out a white jade bottle, which was glowing with a dazzling blue light, and some complex patterns were carved on it, only to see him open the cap of the bottle, and then poured a drop of the special body that shimmered red into the medicine pool.

"Poof!" the liquid fell into the pool.

"Hum!" A strange fluctuation emanated from the medicine pool, and Li Feng felt the Xuan Qi in his body, and became ready to move.

The medicine pool lit up with dazzling lights of various colors, which was very dazzling. Immediately, the water of the entire medicine pool boiled wildly. Constantly bubbling and bursting.

Li Feng suddenly felt that the medicinal liquid around him was slowly rising, and the spiritual power that had penetrated into his body had become even larger.

"Ahhh

Looking at those people whose faces turned red rapidly, the golden-robed old man shook his head slightly, and said: "This spiritual liquid is the secret of the Li family, the entire medicine pool is like a melting pot, the faster the body temperature of a person soaked in the medicine pool rises, it proves that the weaker the person's body, the less energy he can absorb!"

After half a pillar of incense, many people couldn't bear the pain and fell into a coma in an instant.

The people next to the medicine pool immediately scooped up those who had fainted, and these people who had passed out of the medicine pool turned red with their movements, as if they had been cast from pig iron. When their bodies are fished out, their body temperature drops rapidly.

Even Li Tao, because he absorbed a large amount of spiritual power, his face turned red. But Li Feng's face did not change at all.

"This kid, it's a bit interesting!" The golden-robed elder stared at Li Feng in the pool, and a smile couldn't help but appear on the corner of his mouth.

As time passed, one after another people could not withstand the impact of this huge spiritual power and passed out.

Half an hour later, in the pool, only Li Feng and Li Tao were left, and at this moment Li Tao gritted his teeth and was desperately holding on.

"I can't lose to him, absolutely not!" Li Tao said to himself secretly in his heart, but he immediately passed out.

The golden-robed old man smiled and said lightly, "I don't know how long this kid can last!"

The faces of the other four old men also showed a hint of smile.

In this way, another hour passed, Li Feng's face still did not change at all, the five old men showed a look of shock on their faces, at this moment it has been an hour and a half since Li Feng entered the pool, but Li Feng's face still did not change at all, and the five old men all felt incredible.

"Damn, is this kid still human?" Many of the people who were scooped up next to the pool had already woken up, and they had all experienced the feeling of being soaked in the medicine pool, and many of these people couldn't even hold on to a stick of incense, but now Li Feng had been soaking in it for an hour and a half.

At this time, the temperature in the entire hall dropped rapidly, and many people began to tremble.

The faces of the five old men changed slightly, and they said, "Take the others out!"

"Okay!" The guards who were in charge of fishing for people began to let those people take away the people who were still in a coma, and in the entire hall, there were only five old men left, they stared at the medicine pool, only to see that the bubbles coming out of the medicine pool were getting less and less, and at the edge of the medicine pool, a thin layer of ice had appeared, and this thin ice quickly spread in the direction where Li Feng was.

"Let's buy a little more time for this kid!" the golden-robed old man said to the others.

"Okay!" the others nodded, and then jumped into the medicine pool together, and the five of them surrounded Li Feng in the middle, and luckily stopped the spiritual liquid that wanted to freeze.

The spiritual power that poured into Li Feng's body was constantly getting stronger every moment, and Li Feng felt a slight feeling of swelling in his meridians, and every time the time increased, the spiritual power that poured into his body would be twice as powerful. These spiritual powers were absorbed by Li Feng's body cells, making his body cells more powerful.

......

Yuntianju, the residence of Li Feng.

"I didn't expect that this courtyard would have such a powerful prohibition!" Standing at the door of the small courtyard of Yuntian Jutianzi, Bai Xintong's brows furrowed.

"Is there anything special about this courtyard?" Li Hanshuang looked at Bai Xintong suspiciously, she couldn't imagine that a place where Li Feng lived as a waste would attract Bai Xintong's attention.

Bai Xintong nodded slightly, and said: "The method of prohibiting the setting of this courtyard is very special and very clever, I want to study it!"

"What's there to study about this thing?" said Lishuang, pouting disdainfully.

Bai Xintong smiled, then walked to the Tianzi small courtyard, her hands formed complex handprints, and then in the space in front of her, a trace of ripples appeared, and the frost and the girl in green saw complex runes slowly appear in front of them......

Half an hour later, in the hall of the medicine pool, the temperature had dropped to a very alarming level, and the rest of the pool, except for the place where the five elders were trying their best to maintain, had frozen in the rest. The hair, eyebrows, and beards of the five elders were already covered with ice crystals.

"Stinky boy, wake up quickly!" Li Feng's staying power was beyond the expectations of the five elders, and by this time, they could no longer maintain it. Once they are frozen by this ice, their lives will not be saved.

The temperature of this pond changes over time, and it only rises in the morning to noon during the day, making the water in the pool liquefied. After noon, the temperature of the potion pool will drop, and the ichor will turn into ice.

Hearing the shouts of the golden-robed old man, Li Feng suddenly came to his senses in the state of cultivation, and he felt that his physical fitness had improved a lot all of a sudden, although this effect was not as good as the improvement when he absorbed the martial soul fragments, but it was also very terrifying.

"Uh...... What are you?" Li Feng was a little surprised to see the entire hall turned into an ice cellar.

"Don't talk nonsense, hurry up! Remember, you must use your Xuan Qi to isolate your body from the cold qi around you, otherwise as soon as you leave this medicine pool, the spiritual liquid on your body will be frozen into ice!"

Li Feng seemed to understand something, he spread the mad god battle qi all over the surface of his body, forming a golden energy cover, although after Li Feng became a martial artist, he was already able to use the Xuan Qi battle suit, but the condensation of the Xuan Qi battle suit consumed more soul power than the condensation defense cover, so at this time, he chose the former.

Jumping out of the medicine pool, Li Feng suddenly walked out towards the passage.

"Let's withdraw!" the golden-robed old man shouted, and then jumped up in the medicine pool, without their protection, the remaining spiritual liquid in the center of the medicine pool instantly turned into ice.

In the Firmament Hall, all the people were waiting anxiously.

"Why haven't they come out yet?" Li Qingchen's brows furrowed slightly, and now the cold air emanating from the passage mouth was enough to freeze a five-star martial artist to death.

"Could something happen to them?" Li Qinghe also showed a hint of worry on his face.

At this moment, a figure rushed out of the passage, and this person was Li Feng.

A moment later, the five old men also rushed out, and they breathed a long sigh of relief.

"Boom!"

The stone door in the center of the hall slowly closed, and the five faces were a little pale, and they looked at Li Feng, with a hint of relief on their faces.

"This medicine pool baptism, only the first time has the best effect, you all go back, after you go back, seize the time to cultivate, and strive to dissolve all the medicinal power in the body, what we can do for you is so much, I wish you good luck!" said the old man in the golden robe lightly.

"Thank you elders!" Li Feng and the other disciples bowed slightly to these old men, and then, everyone followed Li Qingchen and left the elders' house.

Walking out of the gate of the House of Elders, it was already past noon, and the sky was covered with clouds, and it was a little gray. Li Feng felt that he was full of strength. If before he entered the medicine pool, his comprehensive combat power was comparable to that of a five-star martial artist, then now he dared to fight with a six-star martial artist.

Back at his residence, Li Feng found that the gate of his yard was open, Li Feng gritted his teeth, rushed into the yard, and yelled: "Who the hell is it, get out of here immediately!"

"Someone is coming!" Bai Xintong, who was studying the prohibition at the gate of Tianzihao, immediately stopped.

"Hmph, it's that waste! He's back just in time!" Li Hanshuang sneered and said, "Let's go, let's go find him and let him open this prohibition, I want to see what mysterious things are in here!"
