Issei was waiting for Yang Xin and Ning'er in the inn the following morning. However, Raynare decided to do her own thing for the first time they arrived in this world. She wanted to explore the world on her own. Raynare didn't know where she would be going, but that's why it's fun. Exploring a new world is exciting, but meeting people on the way is even more exciting. Truth be told, Raynare was only doing this so that she could record the iconic lines of Wuxia/Xianxia c-drama, novel, and manhua. Issei knew this. So, why didn't he stop her? That's because Issei knew that she could protect herself.

After waiting an hour, Yang Xin and Xiao Ning'er arrived at the inn. They looked at each other and knew that they were going to the same place. Sparks flew between them, but it didn't last long as they giggled at each other's actions. As they thought, when they headed upstairs, they were both going to the same place, which was Issei's abode. They knocked on the door, and Issei answered.

"Hey, you two are finally here," Issei said. He then asked them to come in. Looking at them, Issei can tell the stage of their cultivation. Ning'er was in the Three-Star Bronze rank, while Yang Xin was in the Four-Star Bronze rank. Not bad. "Hmm… your cultivation is going well. Once you reach Silver rank, you'll be able to learn some of the Heaven's Path Arts, like the Golden Body, Sword Art, Spear Arts, etc.".

Issei then looked at Yang Xin, and then he spoke.

"Now, before we begin our alchemy lesson, I want to test out yours and Ning'er's current strength," Issei said. He then activated the (Training Room – Legendary). This was the safest place for him to test their strength. "Now, show me what you both got at the same time".

Yang Xin and Ning'er nodded at Issei, and they charged at him.

Fast. That's what Issei thought when both women charged at him, but he was way faster than they were. Issei dodged the attacks elegantly and with grace. Ning'er and Yang Xin were amazed at how easily Issei could avoid both their attacks. But this motivated them to try harder.

Yang Xin tried to punch Issei, but he could catch her fist with ease. Next, Ning'er kicked Issei in the back of the knee, but she wasn't strong enough to make it bend. Lastly, Issei wanted to test out their endurance. So, he made his aura explode, suppressing both women.

This is to see how much they could endure before caving in. This was the best way of testing their endurance without hurting them physically.

Issei was smiling like an idiot. Why? Because for the past hour, Yang Xin and Ning'er have been enduring his aura.

The aura surpasses what Issei directed at Shen Yue the other night. This shows how powerful the duo's endurance and willpower are. Yang Xin and Ning'er wouldn't cave in for another two hours. The entire time, the longer the endurance test went on, the stronger the aura that Issei was directing.

Once Yang Xin and Ning'er collapsed, Issei brought them out of the Training Room. Unfortunately, the training room wouldn't heal anyone that hasn't died. So, the two women that passed out needed to be cared for by Issei.

After two hours, Yang Xin and Ning'er finally woke up. Looking at herself, Yang Xin saw that she was wearing different clothes. She blushed as the only possible way was if Issei changed her apparel for her. Looking around, Yang Xin also saw that Ning'er was wearing different clothing. When Issei saw her face, he explained.

"Don't worry, I didn't see anything," Issei said. He then showed her how he changed her clothes without looking. One second, Yang Xin was wearing one set of clothes, and then the next second, she was wearing another. "See? That's how I changed your clothes. I didn't look, I promise. I didn't want to leave you and Ning'er on the sweaty clothes you are wearing after the training".

"I don't mind," Yang Xin said. Why did she say that?! She didn't know. This made her blush. So, she faked clearing her throat and changed the subject. "Ahem! I was thinking, when are we going to begin our alchemy lesson".

"Now, if you're feeling like it," Issei said. He knew that Yang Xin was trying to change the subject. Which he was grateful for. "We're already done with the third volume of the alchemy books, right? If that's the case, then we can do some practical pill making before proceeding to the next volume".

Yang Xin nodded her head. She was excited to see Issei's pill making techniques. Yang Xin wondered if Issei could make Divine Grade Pills. It was said in ancient times that only alchemy prodigies could make such pills.

Yang Xin watched as Issei tool out a pill furnace. It was emitting powerful energy. Yang Xin inspected the pill furnace and couldn't identify the material it was made of. However, the material seemed to be able to amplify the energy given to it.

The furnace that Issei took out was something he made a few days before he headed to the Divine Continent. He made the furnace when he received the (Master Alchemy) from the Gacha. The material he used to create the furnace was Uru. But that's not all. He also used the Heavenly Flames of Transmogrification to refine the Uru, causing it to gain its own True Fire, which is great for alchemy pill creation.

For the pill that Issei was planning to make, it was the Zhenqi Gathering Pill. A pill that is used to help a cultivator absorb the Heaven and Earth energy of the world. This would help speed up the cultivation of those that consume the pill.

Issei threw the required herbs into the furnace and started to refine them by liquifying the herbs and picking only the required properties. Once that was done, Issei mixed the liquified properties. And lastly, he coagulated the liquid into a spherical shape and hardened it. This was a basic pill creation technique, but it was akin to a high-level alchemy technique in Issei's hand.

Once the pill was done, Yang Xin saw that the pill created was transparent with a golden lustre. This indicated that it was a Divine Grade with Peak purity.

"Here, this is a Zhenqi Gathering Pill. It should help you both increase your cultivation speed," Issei said. In one session, Issei was able to make a hundred pills. Which was abnormal as one session should only be able to produce, at most, five to seven pills. And if one is lucky ten pills. Issei divided the pills in half. Fifty for Yang Xin and Fifty for Ning'er. "What did you think of my practical demonstration?".

"It was…spectacular!" Yang Xin said. Not only was the speed at which Issei formed the pills, but the amount he got in one session was abundant. No one can say that they were able to make one hundred pills and one session. "Will I be able to do something like that in the future?".

"Of course! I'll be personally instructing you on how to refine pills the way I do," Issei said. The technique he used was the simplest one that he had. Issei knew a more powerful refining technique, but it was not needed for a simple pill like the Zhenqi Gather Pills. "Now, do you want to try making a pill?".

Yang Xin nodded her head. When she tried to use the pill furnace of Issei, she thought it would be easy, but that was further from the truth. The True Fire of the pill Furnace was difficult to control. If she lost concentration even for a nanosecond, the fire would go out of control and burn the herbs inside the furnace.

Twenty-Five times. That's the number of times Yang Xin had to try before she finally successfully made her pills. Looking at the pills, Yang Xin smiled. Why? Because it had the same pill colour but a different lustre as Issei's. It was transparent with a blue lustre. This shows that it was the Divine Grade with high purity. However, unlike Issei, Yang Xin could only produce one pill, and the purity was a step below his.

"Congratulations. You successfully made a Divine Grade Pill with high purity. With more practice, you might be able to make one with peak purity," Issei said. It was getting late outside. This would be the time Ning'er and Yang Xin headed home. "It's getting pretty late. Are you guys planning to stay here? Or are you both heading home?".

"I need to head home. The elders would be 'worried' if I don't return," Ning'er said. She took her share of the Zhenqi Gather Pills and put them inside her storage rings. Ning'er then said goodbye to Issei. "Goodbye, Ise. I'll see you tomorrow".

"Alright, take care," Issei said as he waved Ning'er goodbye. When Ning'er left, Issei looked at Yang Xin and spoke. "Do you want to continue, or do you want to head home and rest?".

"I'll head home and rest," Yang Xin said. She was exhausted. Yang Xin did attempt making the Zhenqi Pills Twenty-Five times. Plus, she knew that Issei was testing her. "Resting will do me some good. Are we going to continue our practical pill creation tomorrow?".

"We are, but we'll make different types of pills," Issei said. Zhenqi Gathering Pills were one of the easiest pills to make. So, tomorrow they will be doing something more challenging like Soul Nurturing Pills and Body Refining Pills. "Be sure to rest as much as possible because tomorrow I will be making you work twice as hard as today".

Yang Xin nodded. Today, she was exhausted from making a single pill. What would it be like for tomorrow when Issei said they would be making different pills? No matter, she was determined to work hard under Issei. Yang Xin even smiled and couldn't wait for what was to come.
