I'm accumulating points in the cultivation world.

“Let’s team up and have a competition to see who can refine it first,” Old Li said with a smile.

"Of course it's you, Master. I'm not even half as good as you," Tang Doudou said with a smile.

"My disciple, you must not boost the morale of others while diminishing your own prestige," Elder Li said solemnly.

"I understand!" Tang Doudou said quickly.

The two set up the alchemy furnace and began refining. Before long, they opened the furnace at the same time.

The two poured out the marrow cleansing fluid. Elder Li's marrow cleansing fluid was noticeably clearer, while Tang Doudou's looked like it contained impurities.

"Disciple, try it and see how it works!" Old Li smiled and handed the marrow cleansing liquid to Wei Chenyi.

Wei Chenyi thanked his master, then picked up the glass and drank it all in one gulp.

Wei Chenyi quickly absorbed the marrow cleansing liquid, but his body smelled terrible.

"How was the effect?" Old Li asked with a smile.

Wei Chenyi immediately sat down to meditate and cultivate, and sure enough, his absorption speed was much faster than before.

"This marrow-cleansing liquid works even better on people without spiritual power! After using it two or three times, it can even wash away the impurities in the spiritual root and allow one to obtain a single spiritual root!" Tang Doudou said from the side.

Elder Li picked up Tang Doudou's cup of marrow cleansing liquid, drank it down, and then nodded. "As expected, the effect is not obvious for people with high cultivation levels. It's probably because they absorb spiritual energy and have already tempered their bodies and removed impurities without them even realizing it."

Tang Doudou suddenly realized!

"This Marrow Cleansing Liquid can be mass-produced and is inexpensive. However, for those stuck in the Foundation Establishment stage, we could add some other spiritual herbs to make pills, which might improve the quality of the original Marrow Cleansing Pills!" Elder Li continued.

Old Li is indeed wealthy; all he thinks about is making money.

"Then it's up to Master to decide!" Tang Doudou said with a smile.

“As your master, I can’t just take advantage of you. I’ll give you half of the income. All you need to do is provide Longming Sand on time. What do you think?” Old Li said with a smile.

"Master, you're really good at scheming. You even managed to outsmart your disciple," Tang Doudou teased.

"Of course, my disciple, I can't find you for days on end. When I do see you, you come to me asking for a pittance. How can I not squeeze you a little?" Old Li said with a smile.

Tang Doudou smiled and agreed. As for the Marrow Cleansing Liquid, she didn't want to worry about it anymore. She hadn't refined pills in a long time and didn't know if she could still refine a Grade 3 pill.

Even after Long Mingsha was removed, there was still a foul smell in the room, so Tang Doudou lit an incense stick before she could begin refining pills.

But for some reason, I failed every time I tried to refine the elixir today!

Tang Doudou looked at the ruined pills with confusion. It had failed again. What happened?

"You forgot, you lit incense in the room!" The system looked at Tang Doudou's bewildered expression for a long time before finally reminding her.

"What exactly is in this incense? How could it affect alchemy?" Tang Doudou asked in surprise.

"Dragon scales!"

"Dragon scales? Do you have real dragons where you live?" Tang Doudou asked doubtfully.

"Of course, where do you think it came from?"

"I remember you once said that only souls or extremely powerful beings could go to your place. Why are dragons there too?"

"Aren't dragons powerful?" the system asked.

Tang Doudou was stunned for a moment, "That's a legendary dragon, how could it not be powerful?"

"That won't work?" the system said smugly. "However, we also have a base on Dragon Island."

No wonder. But this system is quite powerful.

Tang Doudou then remembered the dragon scale she had collected and quickly took it out to show the system, "Take a look, isn't this a dragon scale?"

“These are dragon scales,” the system replied.

"Does this mean that there is a Dragon Island near Turbulent Island?"

"Dragons are not social animals; they prefer to live alone. It's normal for dragon islands to be scattered all over the world."

Tang Doudou was thrilled. "I'm not going to refine pills anymore! I'm going to find Dragon Island!"

After Tang Doudou finished speaking, she put away the alchemy furnace and headed towards the direction of Turbulent Island.
