The ninth-grade pill is the pill under the rules. Taking the pills the strongest can be promoted to Taiyi Jinxian. Tang Quan can already produce this pill, but it will never be sold randomly. As the saying goes, things are rare and expensive. If you tell others that you can build a few top-level immortal weapons every day, even the demon city will definitely be killed.

Looking at the masked woman in front of him, Tang Quan did not use his eyes that could see through all the blocked eyes as a peep. He could sense that the other party was born with a powerful charm. Although it did not work for him, he could sense that the other party had no hostility. It seemed that buying high-end pills was still sincere.

Tang Quan shook his head and said:

"The eighth grade pills can be refined occasionally, but the ninth grade failure rate is too high. I used to refine one or two pills, but unfortunately I can't afford that cost, so I haven't refined ordinary elixirs."

The charming eyes lit up and said happily:

"So can Mr. Tang refine it? In this way, if Mr. Tang refines elixirs of grade 8 or above, what if I am willing to buy it at a price of two levels on the market?"

Pills are called priceless, because no one in the demon race can refine this thing. When Tang Quan smiled and said:

"If I have the chance, I will try again, and if I succeed, I will sell it to the customer."

Mei nodded and smiled:

"Since that's the case, then we'll make it. If Mr. Tang makes it, please keep it for me and I will definitely come and buy it."

Tang Quan promised, and Mei left quickly. When Tang Quan covered the gate and blocked the sight of the demons who were still peeping around him, he threw out a big night pearl in the air with a swaying hand, and then he walked to a stone chamber behind the store and sat cross-legged to calculate the income of the day.

Selling all the medium and low-level elixirs and equipment is not as good as the charming person. However, selling high-end goods is a very small transaction, and small profits and low sales and cost-effective products for customers are the rules for long-term business.

In the following time, Tang Quan began to refine a large number of medium and low-level equipment and pills, but secretly peeked at various news about the Demon City at other times. However, he did not break into the Demon Mountain because he found that there were natural formations on the Demon Mountain, and cracking them would easily be discovered. If he wanted to avoid being discovered, it would be fine unless he lifted the seal to the realm of the Heavenly Dao.

However, Tang Quan still learned from some advanced demons that Luohu was in seclusion. Luohu, the guy who plotted against Tang Quan, was interrupted and was severely injured by himself. I guess he would be scared when he thinks of Tang Quan's sword.

A master in the late stage of the quasi-saint plotted against someone else and was severely injured by someone's counterattack. This would be a huge blow to Luohu, who claims to be the strongest master in the prehistoric world. Similarly, Hongjun, who was suppressed by Tang Quan's cultivation, must be the same.

The two of them had already achieved the innate saints who controlled the destiny of the prehistoric world and knew what kind of cultivation was above the point. Therefore, to take revenge, they had to break through to the innate saints and then become agents of the heavenly way, so that they could assist the attack with the power of the prehistoric world, so that they could settle the score with Tang Quan again.

Retreat is to reach the peak state and then complete the fate of the other person. The battle of fate is also in the countdown. Two people with fate who were frightened by Tang Quan both chose to retreat and have the power to control the world as soon as possible.

They never dreamed that Tang Quan had already arrived in the Demon City and even knew the identities of the two. He wanted to have a destiny battle here, and he could not kill them, so Tang Quan would also disgust them for a while.

Tang Quan's store opened every thirty days, and every time it attracted a large number of demons from the Demon City to purchase, and at the same time sold him various materials and materials.

In this way, Tang Quan used the method of plucking the sheep to create equipment and pills. He used the method of wool to pluck the demon city for 100,000 years. Now, Mr. Tang’s name is well known to everyone among the demon clan. More than one billion pieces of equipment and a large number of pills were taken. It is said that the boring people in the demon clan had calculated that the largest tycoon in the demon city was Mr. Tang.

Is this really the case? Tang Quan can give a direct negative answer. Unless he expands sales, the wealthiest place in the Magic City is the Magic Mountain. The Demon Army with more than one trillion yuan is just training and mining various mineral veins. That is the richest place in the West.

Strictly speaking, Tang Quan couldn't even enter the top five rich men because the four demon generals controlled their respective armies and only handed over 10% of all supplies to the Demon Mountain. Except for the three floors, the rest were all used by the army.

Therefore, the wealth controlled by the four great demon generals is only less than that of Demon Mountain, but they are too rich compared to Tang Quan, but because it is a group nature, Tang Quan is indeed very rich by himself.

Tang Quan set out to be not only rich but also richer. As his reputation grew, the number of young rich people who came to him to buy equipment and pills began to increase. Even every time Tang Quan opened the door, he would buy top-level equipment and pills.

After millions of years, the hills around Tang Quan's No. 1 grocery store in the Demon City have been covered with various caves. Street stalls are not bad at taking advantage of Tang Quan's popularity. Tang Quan has almost never lacked people sitting and bragging on the seats placed on both sides of the stone arch bridge.

"Dongdongdongdongdong..."

A burst of rapid knocking sound came from outside, and Tang Quan frowned. It was more than five days before the new door was opened. Those who knew that he would never disturb him. Listening to the urgent knocking sound, Tang Quan shook his hand and a picture appeared in the mysterious mirror;

A blond beauty who looked like a human 14 or 15 years old was knocking on the door anxiously. As for why she was so anxious, she looked carefully at her back with three pairs of wings, two of which had been broken, and the little beauty looked extremely anxious with sweat beads on her forehead.

Tang Quan looked out of the room curiously, and waved his hand to open a gap. Then the little beauty rushed in. Seeing Tang Quan, the little beauty's eyes were excited and her body twitched, and she fell to the ground.

"Uh... I fell down. I was forcing me to save people. I don't know if this girl has any fairy stones or treasures to pay the bill?"

Tang Quan murmured and pulled the little beauty to her and closed the door. He hugged her into the room, followed the other party's broken pair of wings with his hand, pressed his fingers on the other party's pulse, and a stream of Maha's immeasurable aura pushed directly along the girl's meridians.

A black mist was forced out of the little beauty's body. Tang Quan held the black mist in the air and put it in a bottle and said:

"Xiaohong, what do you think of this thing?"

After taking the bottle in the cultivation space, the red man took the bottle and put it into the detection equipment. After a while, the detection data appeared. She frowned and said:
Chapter completed!
