The reason for selecting Liu Su is that she has been exposed to cultivation for the shortest period. Since this is an experiment on the efficacy of the Tianren Pill, she is the ideal candidate. As Qin Feng had anticipated, the changes following the consumption of the pills are remarkably evident. When she took her tenth pill, she had already surpassed the Hua Zhen stage and entered the Xingkong stage. After consuming thirty pills, she advanced from the lower grade to the mid-grade. Then, upon taking fifty more, she progressed from mid-grade to the superior grade. For safety’s sake, the first-day experiment concluded here. The "Girls' Literature" section promptly updated, primarily concerned that Liu Su might not withstand the rapid pace of advancement. Moreover, she specifically consulted with her "Peony Brother," confidently inquiring whether the Tianren Pill could be consumed in large quantities without regard to dosage. The response confirmed that it could—since even ordinary Tianren pills work, it's certainly feasible for this superior-grade pill, which is clearly one level above the ordinary ones. After a restful night, the experiment resumed the following day. The beautiful senior student arrived at the living room wearing a casual outfit, yawning slightly. Last night, she had been the main focus of Qin Shao's attentions, being kept busy and stirred all evening, so she felt a bit worn out. Yet this didn't prevent her from continuing her medication. Drawing on her experience from the previous day, she picked up the bottle and took the pills directly into her mouth, swallowing them headfirst. "Indeed, Tianren Dan proves beneficial for cultivators. Why didn't we share it with our sisters right away? We should all raise our cultivation levels together," she said. "No. We must fully absorb its essence," Qin Shao insisted. The beautiful senior student said nothing further. She counted out twenty pills and swallowed them one by one. At the fourteenth pill, her movements paused, and then she closed her eyes. Qin Shao's eyes lit up, "She's advancing! The effect of the pills is truly excellent." The other young girls were all delighted. Cultivation, for cultivators, is often monotonous and tedious—especially for those who've grown accustomed to taking shortcuts. A few minutes later, the senior student opened her eyes and said, "I've successfully entered the Kui Tian stage. Should I continue taking pills?" "Yes," he nodded. The senior student looked slightly disappointed. "No need, then... It's just like sugar beans." It's easy to get overwhelmed even with so much. Yesterday, I was still at the peak of the Hua Zhen stage. Today, I've already jumped to the lower tier of the Kui Tian stage. The progress has come too quickly—it feels a bit unreal. "Take a few more," the sisters encouraged. "At the very least, you should reach the peak of the Kui Tian stage." She simply couldn't refuse their enthusiasm and kept taking the pills one after another. Three hours later, Qin Shao beamed and slammed her table: "Since the Tian Ren Pills have proven effective, we should produce them in large quantities. Wei Wei, you'll lead this effort. Everyone else should participate as well. Let's aim to generate enough pills in a short time so that we can all ascend together." "Done. Count on me," Lin Cai Wei said with confidence. Based on Liu Su Fu's experience in advancing through the ranks, it can be roughly estimated that one person transitioning from the Hua Zhen stage to the Yuan Sheng stage requires about one thousand two hundred Tian Ren Pills. With so many daughters in the family, that's quite a number.
