Gu Qin and Qin Xiansheng watched as they left. Once they were gone, Qin Xiansheng looked back.

Gu Qin pulled his hand. "Xiansheng, I’ll go down to check. Wait for me."

Qin Xiansheng didn’t want her to go but relented. She took off her shoes, socks, and coat, waving before diving into the water towards the faint golden light.

Not even her feet sank into the mud. She slowly moved towards the pale golden light, which was covered in mud. Gu Qin sent a void talisman to strike the mud beneath her feet, dispersing it and making the pale golden light clearer. She leaned down and felt around in the mud with her hands. Soon, she touched a smooth, cold bead.

Gu Qin was delighted; she hadn't expected her guess to be correct. She had actually found a dragon stone here.

This dragon stone should have been left behind by the green python when it transformed into a dragon. It could also be considered a magical weapon. Similarly, it was a rare treasure that could make countless cultivators go mad, and it could also help Brother Ji.

These days, she had searched online extensively and carefully recalled what her master had told her and the knowledge he had imparted. She knew that there were many ways to cultivate yin beasts, and the most powerful and vicious ones were those cultivated using human bodies as hosts. Because the yin beast must live with its host for some time, it develops feelings for the host. When the host kills it, the yin beast harbors resentment and will quickly devour the host.

When the yin beast emerges from the host's body, the host is already dead. In most cases, before the yin beast can fully form, the host cannot bear the pain and dies. Even after the yin beast forms, if it wants to emerge, the host only has one path: death. The situation with Big Brother Qin was almost unheard of, as he grew together with the yin beast. Therefore, it was almost impossible for Big Brother Qin to safely rid himself of the yin beast.

However, with a heaven-defying treasure, things would be different. At least, there was a glimmer of hope. Heaven-defying treasures were extremely rare; they were often something one could only hope to find once in a lifetime. Gu Qin hadn't expected to find such luck herself.

Good deeds indeed bring rewards. If she hadn't intended to help solve the thing in the reservoir, how could she have stumbled upon such a heaven-defying treasure? It was almost like finding a treasure for free.

The dragon stone wasn't large, about the size of her thumb, with a smooth, cool feel. Gu Qin didn't pay attention to anything else at this moment and clutched the dragon stone as she swam toward the shore.

She soon emerged from the water. Qin Xiansheng, who was waiting on the shore, breathed a sigh of relief. Gu Qin also let out a breath of relief. She hadn't expected to find such a heaven-defying treasure so easily. Usually, such treasures were guarded by other spiritual beings, as animals were more sensitive than humans. But she hadn't encountered any guardian here.

But thinking about it, she realized that this was left behind by the green python when it transformed into a dragon. At that time, the lake was full of the green python, leaving no room for other spiritual beings. A mountain couldn't accommodate two tigers. Moreover, the transformation had only happened a few decades ago. The creatures in the lake had yet to develop any spiritual qualities, so they wouldn't recognize such a heaven-defying treasure. If it were in a deep forest, it might have been discovered long ago by a spiritually awakened animal.

After a while, Gu Qin swam to the shore and, without delay, pulled Qin Xiansheng toward the car park, "Big Brother Qin, we need to leave these places quickly."

Qin Xiansheng could feel the object in her hand and didn't ask further questions. He first took his clothes to dry her hair and body before holding her hand and getting into the car to drive back to the city.

After leaving the village, Gu Qin finally opened her palm to look at the object in her hand. It looked like a smooth stone, milky white, emitting a faint glow. Even after being submerged in mud for years, it remained glossy and unsoiled.

A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.

If she hadn't opened her third eye, Gu Qin could still sense the fluctuations coming from the dragon stone. This thing needed to be used quickly. She held it up for Qin Xiansheng to see, "Big Brother Qin, look at what I found in the water."

Actually, Gu Qin had hesitated a bit before diving in. Without opening her third eye, her cultivation level wouldn't have allowed her to find it. And if she did open her third eye, how would she explain it to Qin Xiansheng? Even if Qin Xiansheng had gone in, he might not have found it either. So, after a moment's hesitation, she decided to dive in. After all, finding such a treasure was a rare opportunity, and she wouldn't let it go.

They hadn't spent much time together, and she was reluctant to reveal her secrets to him. However, she could tell that Qin Xiansheng was a good person. If he were greedy, he wouldn't have helped her subdue the Liuming.

So, after a brief hesitation, she dived in without a second thought.

Qin Xiansheng glanced at the dragon stone and was surprised but didn't ask further, "Gu Qin, thank you." He knew that she had dived in to find the dragon stone for him. With such a heaven-defying treasure, his chances of expelling the yin beast from his body greatly increased.

Gu Qin smiled, "Big Brother Qin, you once helped me subdue Liuming, and I promised to help you get rid of the yin beast. Now, with this treasure, our chances are much higher. Big Brother Qin, let's try it when we get back."

A dragon stone was essentially an item to enhance cultivation. To expel the yin beast from Qin Xiansheng's body, they needed to use it.

Qin Xiansheng turned his head to look at her, his heart surging with emotion.

The car soon returned to the city. Qin Xiansheng brought Gu Qin to his residence, which was closer than going back to her home, where it would take another half hour to drive. His place was a newly built neighborhood, bought by his assistant a couple of years ago. The space was quite spacious, and he lived alone, so he had redecorated it. There was only one main bedroom, and no guest rooms. The rest of the space was converted into a gym, with a minimalist design featuring black, gray, and white colors.

Simple and elegant, though somewhat dull, it suited him well.

Qin Xiansheng led Gu Qin into the main bedroom. He was also wet and changed into a pair of pants in the bathroom before coming out, tossing his dirty clothes into a basket. He then said to Gu Qin, "Go wash yourself with hot water first, and I'll go buy you some new clothes."

Gu Qin nodded obediently. Her hair was still damp, and the lake water was very dirty, sticking to her skin uncomfortably.

Qin Xiansheng handed her two clean towels and bath towels, "I'll be outside."

After he left, Gu Qin went into the bathroom, stripped off her wet clothes, and threw them in the basket. She washed herself thoroughly. She searched the bathroom and found only one bottle of shower gel and one bottle of shampoo, both ordinary brands. The bathroom seemed empty.

Gu Qin smiled, washed herself, wrapped herself in the towel, and came out. The towel was big enough to cover her completely. She sat in the room waiting for Qin Xiansheng.

Ten minutes later, she heard the sound of the door opening. Gu Qin ran barefoot to the living room. Seeing her like this, Qin Xiansheng couldn't help but smile slightly and handed her a bag, "Quickly go change in the room. I'll wait outside for you."

Gu Qin went back to change into the clothes. The set included simple sportswear and conservative cotton underwear, which were a bit small. Gu Qin's chest had developed rapidly recently, and she was now the size of two buns. He probably hadn't bought such items for anyone before, so they were a bit tight. Gu Qin laughed, put on the slightly ill-fitting underwear, and then the sportswear.

The sportswear fit perfectly. When she came out, she found Qin Xiansheng sitting on the couch in the living room. He was sitting casually, his long legs crossed, gazing out the window. He turned his head when he heard her come out.

Gu Qin walked over, "Big Brother Qin, you haven't washed yet. Go take a shower first."

Qin Xiansheng grunted in agreement and went to take a shower. He came out wearing casual clothes and went to the kitchen, "It's already two o'clock. I'll cook something to eat." He usually cooked for himself, and the refrigerator had plenty of ingredients. With Gu Qin here, he steamed rice, stir-fried broccoli, made tomato beef stew, and pan-fried fish. All simple home dishes, which he completed in half an hour.

By the time they finished eating and washing the dishes, it was three o'clock. They sat in the living room. Gu Qin took out the dragon stone from her pocket and handed it to him, "Big Brother Qin, this is for you."

Qin Xiansheng didn't refuse. He really needed this treasure and held the slightly cold dragon stone in his palm.

Gu Qin asked, "Big Brother Qin, when do you plan to start? How about tomorrow? We shouldn't delay. Tomorrow is Monday, and I can take two days off from school. I'll tell my mom, and we can find a suitable place. I'll protect you while you force the yin beast out of your body."

"Alright," his voice was soft. "Let's do it tomorrow."

That night, Gu Qin went home for dinner. Qin Xiansheng didn't go to the Gu family's house, saying he had some preparatory work to do. After dinner, the four of them sat in the living room watching TV. Gu Qin took the opportunity to say, "Mom, I have something to do these two days and need to take leave from school. I might not be back tonight. I'm telling you beforehand."

Cheng Yinxiang asked, "What is it?"

Gu Qin hesitated, "It's related to feng shui, helping someone with feng shui."

"Going to another place to help with feng shui?" Gu Jia said softly, "Are you going with Qin Xiansheng? You two, being a young man and woman..."

"Gu Jia!" Cheng Yinxiang got angry, "What inappropriate words are you saying? Can you talk to your sister like that?"

Gu Jia sighed, "I just wanted to remind her. She's a young girl now, and dating isn't always good."

Gu Qin muttered, "Big Brother, don't talk nonsense. Qin Xiansheng isn't that kind of person, and this time it's really important."

Cheng Yinxiang nodded, "Alright, be careful on the road. I've noticed that Xiao Qin is a considerate person, and our daughter is decisive. I don't worry about that anymore."

That night, Gu Qin called her homeroom teacher and requested leave for the next day. The teacher readily agreed, asking her to submit the leave slip the following Wednesday. Given Gu Qin's excellent grades and frequent absences, the teacher was happy to accommodate her.
