Peng!
The door of the dormitory was slammed shut, and Tang Lei was locked outside again.
Ye Xuan took out the medicinal materials for refining the Spirit Gathering Pill and the Auspicious Clouds Cauldron, sat cross-legged on the bed, and began to refine the Spirit Gathering Pill.

Like magic treasures, the pills were divided into Class 9 and 18 grades. They were respectively the Dark Pill, the Treasure Pill, the Spiritual Pill, the Immortal Pill, the Divine Pill, and the Holy Pill.
Although the Spirit-gathering Pill was only a low-grade Mysterious Pill, it was still a grade. It was not something that could be compared with the previous Bone Growing Pill. With Ye Xuan's current cultivation, it would take him a lot of effort to refine it, so Ye Xuan did not dare to be careless.
He first adjusted his condition and mobilized the remaining Genuine Qi in his body. The next moment, with a thought, the Auspicious Clouds Cauldron floated up and the lid of the cauldron automatically opened.
Then, he made a seal with his hand and pointed to the Auspicious Clouds Cauldron. The Auspicious Clouds Cauldron instantly expanded in size. At the same time, a suction force came out and sucked in all the medicinal materials.
The lid of the tripod was closed, and the seal in Ye Xuan's hand was inserted into the Auspicious Clouds Cauldron one after another. At the same time, a continuous stream of True Qi was poured into the tripod. However, the True Qi consumed a lot of energy to refine the Spirit Gathering Pill. Before long, a layer of dense sweat appeared on Ye Xuan's forehead, and his face became pale.
If it weren't for the fact that the True Qi recovered very fast under the full operation of the Heaven and Earth Emperor's Taoist Incantation, Ye Xuan would have been unable to hold on any longer. Even so, his body and mind were severely consumed.

Time passed little by little, and it could be seen that Ye Xuan's face was full of fatigue. Gradually, a wisp of medicinal fragrance floated out of the tripod. At a certain moment, the Auspicious Clouds Cauldron shook slightly, making a pleasant crisp sound, and the lid of the tripod bounced off.
The next moment, twelve emerald-green pills were spat out of the tripod and swirled. Ye Xuan waved his hand and directly put the pills into a porcelain bottle that had been prepared in advance.
It was not until this moment that Ye Xuan heaved a long sigh of relief.
The Auspicious Clouds Cauldron fell from the sky and returned to its original size. Ye Xuan put the pill away, got up, and put the Auspicious Clouds Cauldron back in its original place.

Then Ye Xuan thought about it. He took out a Spirit-gathering Pill from a porcelain bottle that contained the Spirit-gathering Pill and put it in a box.
As expected, Tang Lei did not leave when he opened the door. Seeing Ye Xuan open the door, a smile appeared on Tang Lei's face. At the same time, he looked curiously into the dormitory, sniffed hard, and his eyes flashed with surprise.
Looking at Tang Lei, Ye Xuan was a little silent. He was not a heartless person, but his heart could not be healed. It was destined that he could not accept Tang Lei.
Every time Tang Lei called him big brother, he would always remind him of his former good brother. Once upon a time, his good brother called him big brother like Tang Lei. But at the critical moment, it was this good brother who killed him. If he had not been lucky enough to be reborn, he would have been dead by now.
"Come in, I have something to ask you." Ye Xuan said, then turned back to the bed and sat down.
"Brother, what do you want to know? I'll tell you." Tang Lei said in surprise and walked into the dormitory excitedly.
"If you call me big brother again, I will throw you out." However, Ye Xuan's cold voice sounded like a basin of cold water pouring down on Tang Lei's head, which made Tang Lei, who was originally happy, instantly depressed.
"But why didn't I call you big brother?" Tang Lei asked in disappointment.
"You can call me Ye Xuan," Ye Xuan said.
"Oh! Then I'll call you Brother Ye Xuan in the future." Tang Lei said and looked at Ye Xuan with expectation.
Ye Xuan looked at Tang Lei coldly, opened his mouth, and finally gave up. "Since Tang Lei is willing to call me that, just call me that! It's just a title, and I don't want to argue anymore."
"Are you an Ancient Warrior?" Ye Xuan asked.
Hearing this, Tang Lei was stunned. He didn't expect that Ye Xuan could see through it. But he didn't think about hiding anything, so he honestly admitted it. "Yes."
"Tell me about the Ancient Warriors and their strength division," Ye Xuan said.
"Brother Ye Xuan, aren't you also an Ancient Warrior? How come you don't know?" Tang Lei asked in confusion.
"Just say it," Ye Xuan said coldly.
"Oh!" Tang Lei replied with grievance. He gave Ye Xuan a resentful look, which made Ye Xuan uncomfortable. Then Tang Lei said, "My master told me that the ancient martial artists originated from the Qi Practitioners in the Qin Dynasty. At first, people pursued longevity, but later they gradually evolved into the current ancient martial artists.
Nowadays, the strength of the Ancient Warriors is divided into Clear-strength, Concealing-strength, Transforming-strength, Vigorous-strength, Elixir-strength, Vigorous-strength, and Elixir-strength. They are also called Grand Masters and Great Masters. Each stage is divided into four small realms, namely Early-stage, Middle-stage, Late-stage, and Peak."
Ye Xuan listened quietly. After learning about the division of the strength of the Ancient Warriors, he made a comparison in his heart. From the Qi Refining stage to the Grand Completion stage, every realm was divided into the early stage, the middle stage, the late stage, and the peak. This was the same as the Ancient Warriors.
Han Zhang once said that he was an Ancient Warrior of Transforming Strength, which meant that the Qi-refining Stage was about the same as the Transforming Strength of the Ancient Warriors. The Foundation Establishment Stage was equivalent to Star Strength, while the Gold Core Stage was equivalent to Elixir Strength.
In this way, as long as his cultivation reached the Nascent Soul Realm, he could defeat all the Ancient Warriors. As long as he reached the Gold Core Realm, the Ancient Warriors were nothing to him. After all, compared with the Ancient Warriors, the cultivators had more means and attacks. In the same realm, the Ancient Warriors were definitely no match for the cultivators.
Ye Xuan inexplicably breathed a sigh of relief in his heart. The presence of the Ancient Warriors gave him the pressure. He believed that with his foundation, it would not be difficult for him to cultivate to the Gold Core stage again, and it would not take long.
"Is there a lot of Ancient Warriors?" Ye Xuan asked. There were too many ants to kill. Thinking of Han Zhang, Bai Zhining, Bai Jingmin, and others he had met before, he couldn't help but be vigilant again.
His arrogance didn't mean that he didn't have a brain. He had just recovered a little cultivation, so he didn't want to be defeated in a ditch.
"Well... I don't know exactly how many Ancient Warriors there are, but I don't know how many of them. Moreover, Ancient Warriors seldom travel among ordinary people. Even if they appear, they hide their identities, so it's very difficult to meet them." Tang Lei explained.
"Yes! You can go back!" Ye Xuan said.
"Ah?" Tang Lei cried with a disappointed face, and then said unwillingly, "Brother Ye Xuan, I have no place to go. I don't want to stay in the Bai Family. Just let me follow you! I can protect you. And if you have anything to do, I can do it for you. I promise I will do it for you."
After saying that, Tang Lei looked at Ye Xuan with expectation and had no intention of leaving.
Ye Xuan looked at Tang Lei with a headache. He knew that Tang Lei couldn't get rid of him. Unless he killed Tang Lei, he couldn't do it.
Then he thought about it. It was not impossible to keep Tang Lei. At least with Tang Lei around, he didn't have to do anything. He could use more time to cultivate. He had planned to send the Spirit Gathering Pill to Han Zhang. Now that Tang Lei was here, he had to make a trip.
"It's okay to stay. Please help me send this to the Pavilion of Herbs and give it to Mr. Han," Ye Xuan said and handed the box containing the Spirit Gathering Pill to Tang Lei.
"I know, Brother Ye Xuan. I will go now." Tang Lei took the box excitedly and said happily. Then he left in a hurry, as if he was afraid that Ye Xuan would go back on his word.
Looking at Tang Lei's disappearing back, Ye Xuan was a little absent-minded. He couldn't understand why Tang Lei insisted on taking him as his big brother and insisted on following him. He didn't believe that it was because he said something on Tang Lei's behalf at the Bai family's door.
However, if he couldn't figure it out, he might as well not think about it. Anyway, sooner or later, he would find out. Even if Tang Lei had some unspeakable secrets with him, he didn't care. Tang Lei's strength was not bad. He should have reached the peak of Transforming Strength, but it was still a little bit difficult to deal with him.
Looking at the sky outside, he didn't expect that an afternoon had passed in the alchemy process. At this time, the sky was getting dark, and Ye Xuan couldn't wait to verify the effect of the Spirit Gathering Pill.
So he got up and went straight out of the dormitory and rushed to the artificial lake, where the Spiritual Qi of the school was the strongest. He could only achieve the best effect by taking the Spirit Gathering Pill there.
When he came to the artificial lake, it was still next to the smooth stone, or the place where he practiced yesterday. Ye Xuan sat down cross-legged, and then took out a Spirit Gathering Pill and put it into his mouth.
The Spirit Gathering Pill melted as soon as it entered his mouth. Ye Xuan hurriedly ran the Universal Emperor's Taoist Incantation. Under the influence of the drug, the cultivation method worked faster and its power became stronger. In an instant, all the Spiritual Qi in the school was attracted, as if there was an invisible big hand trapping all the Spiritual Qi around Ye Xuan.
As time went on, the Spiritual Qi around Ye Xuan began to mist. Although it looked very light, this kind of situation should not happen in such a place as the earth where the Spiritual Qi was thin.
At this time, Ye Xuan was in both pain and happiness. A large amount of Spiritual Qi poured into his body, which made his meridians almost split. His body was as painful as being cut by a knife. If his body hadn't been washed and marrowed, he would probably explode and die at this time.
However, it was just for Ye Xuan. He hoped that this kind of pain could last as long as possible. Looking at the gradually growing True Qi in his body, at this speed, he could reach the peak of the Qi Refining stage within a week.
However, heaven did not grant his wish. His idea was about to fail. Soon, all the Spiritual Qi in the whole campus was consumed by him, forming a Spiritual Qi vacuum zone. It was impossible for him to recover tonight. He had to stop practicing and open his eyes.
"I almost broke through to the middle stage of Qi Refining. It's a pity." Ye Xuan sighed and was a little disappointed. Then he thought, "It seems that I have to find time to go out and see if there are any places with dense Spiritual Qi around. My cultivation is not high now, so I can cultivate here, but I have to make plans for future cultivation as soon as possible."
Thinking of this, Ye Xuan suddenly felt a pain in the middle of his eyebrows and warned in his heart. The next moment, without thinking, he instantly rolled to the side.
Peng!
The ground exploded, and a shallow pit the size of a bowl appeared where Ye Xuan was sitting.
At this time, Ye Xuan's face was livid, and his eyes burst out a cold killing intent. Although he had not come into contact with it, he could guess a little in his heart. If it could cause such an effect and make him feel threatened, it could only be a heavy sniper rifle. Someone wanted him to die.
