After the competition, Ye Lingyue followed Ye Fengyu and returned to the northern estate.

 Ye Fengyu said nothing and did not look so good. After returning to the northern estate, she ignored Ye Lingyue and went back to her room.

 “Is Mother angry with me?” Ye Lingyue held Aunt Liu and asked.

 “Little Miss, Third Young Miss is not angry with you. She is worried about you. When you were in the mountains for a month, she was always thinking about you,” Aunt Liu comforted after hearing the uneasiness in Ye Lingyue’s voice.

 Hearing this, Ye Lingyue felt a warm feeling in her heart. Although she was not the ‘mentally challenged girl’ anymore, she could still feel Ye Fengyu’s concern all the time even after she had recovered her consciousness.

This time, Ye Fengyu did not hesitate to stand up against Ye Fengcheng in her attempt to protect Ye Lingyue.

From her room, she could hear the sounds of her mother coughing intermittently. Ye Lingyue knew that her mother was not feeling well because she had used most of her elementary force.

 If only she could find the fifth-grade pill. But then again, that particular pill needed tens of thousand taels of gold, and where was she going to get it? Ye Lingyue frowned.

 After giving Aunt Liu a wild game animal to cook, Ye Lingyue went back to her room.

 She took out the jade she received earlier on and looked at it in her palm.

 The jade was not that big and the craftsmanship was only well-to-do. It was only the size of a child’s palm, and the emerald green body of the jade looked a little gray under the light.

 “It doesn’t look special,” Ye Lingyue mumbled.

 Dark Elemental Jade could speed up the martial arts practitioner’s absorption of elemental force. However, since Ye Lingyue was using the Gathering Elemental potion, her elementary force absorption was faster than that of ordinary people.

 When Ye Lingyue was about to throw the jade aside, the Qian cauldron on her right hand trembled.

 Baffled by what was happening, a white puff of air suddenly appeared in the cauldron and it looked like a strand of hair.

“Is this the cauldron breath?” Ye Lingyue recalled that in Hongmeng’s letter, he mentioned that the cauldron was spiritual. It was used to refine medicine all year round and the cauldron would produce a special gas called cauldron breath. What Ye Lingyue was witnessing was the exact cauldron breath that he had mentioned.

 When that white cauldron breath saw the Dark Elemental Jade, it rolled and rushed towards it as if it were delicious food.

 When the cauldron breath dove into the jade body, a strange image suddenly appeared in Ye Lingyue’s mind.

 The jade in front of her eyes disappeared and everything turned into a patch of emerald green before her. Was she actually seeing what was inside the jade?

Different from what Ye Lingyue saw earlier, she saw a dozen small black spots after the cauldron breath entered the Dark Elemental Jade. Those black spots must be the impurities inside the jade.

 These black impurities were the reason the jade was a grade lower.

 The cauldron breath became extremely active when it saw the black impurities. It moved around and ate up the small black spots.

 In a short amount of time, the black spots inside the jade all disappeared and the color of the jade became greener.

 The cauldron breath by then looked a little cloudy, and it went back into the cauldron after it satisfied itself with ‘eating’. It no longer moved about afterward.

 This scene stunned Ye Lingyue.

 She looked at the Dark Elemental Jade once more and realized how clear it had become after the cauldron breath purified it. It looked like a pool of lake water, and it was as if the craftsmanship was re-done, making it fuller and more exquisite this time.

 The most peculiar thing? The jade felt cool as she held it in her hand.

 If Ye Qing and his father were to see the jade again, they would not guess that it was the same inferior grade Dark Elemental Jade they once had.

 Since Ye Lingyue was bad at recognizing the changes that happened with the jade, she let Ye Fengyu check it.

 Seeing the item, it rendered Ye Fengyu stunned!

 “Where did you get this Dark Yin Jade?”

 “I won this jade from Ye Qing.” Ye Lingyue felt strange.

 “But you won a Dark Elemental Jade, how did it become a Dark Yin Jade?” Ye Fengyu’s eyesight was better than Ye Lingyue.

 Dark Elemental Jade was an inferior grade spirit jade used to gather elementary force, but Dark Yin Jade was a medial grade spirit jade used by Postnatal martial arts practitioners to absorb the Yin energy to break through to the Postnatal realm.

Although it was just a word difference, the price had quite the contrast. A piece of Dark Yin Jade the size of a nail was worth five hundred silver taels. The one Ye Lingyue possessed was worth at least one thousand silver taels.

 If Ye Fengcheng knew that he had lost a Dark Yin Jade, he would not have given it up so easily.

 One thousand silver taels! Ye Lingyue could not help sweating in her palms. It was a pity that one thousand silver taels still was not enough to buy a fifth-grade pill for her mother.

 As for how the Dark Elemental Jade became a Dark Yin Jade, Ye Fengyu did not think much about it.

 “Yue’er, keep this piece of jade properly and don’t let outsiders find out about it. After you break through the fifth level of body tempering, you can use the Dark Yin Jade in many ways. You can use it to separate the Yin energy in the elementary force from the sky and earth, train your muscles and bones, and use it to break through the Postnatal realm.”

At the beginning of the fifth level of body tempering, a part of Yin energy could be integrated into the body. The earlier the integration, the more beneficial it would be for Postnatal cultivation in the future.

 Ye Fengyu thought her daughter had only broken through the fourth level of body tempering. Little did she know, she was already at the fifth level.

 “I understand. By the way, Mother. When I was cultivating in the mountains, I found a type of wine by chance, and it somehow helped me breakthrough. You should drink some of it too, and it may be good for your injury.” Ye Lingyue took out a small bottle of Hundred-fruit wine.
