"Drink!" The next moment, Ling Yunfeng snorted lightly, his handprints changed rapidly, and the martial qi filled with the veins frantically rushed towards the extremely full sea of qi.

"Bang!"

In an instant, I saw a faint muffled sound coming from within the sea of qi, and the space within the sea of qi suddenly expanded rapidly, and the originally full space of the sea of qi became dissatisfied because it expanded again.

Then the aura around Ling Yunfeng's body instantly rose rapidly, and an invisible energy in the heavens and the earth directly converged, rushing directly into the body from the pores of Ling Yunfeng's skin, and this aura had been climbing to a certain level before stabilizing, and gradually stopped fluctuating.

"Whew, have you broken through to a dual martial artist?" Feeling the aura around him that was much stronger than before, and the majestic martial aura in his body, Ling Yunfeng breathed a sigh of relief, and his face showed a touch of joy.

Ling Yunfeng didn't expect that he had only refined the Tsukidan and could break through to the level of a double martial artist with less than eighty percent of his medicinal power, he had also taken the Tsukidan before, and based on his previous experience, he estimated that it would not be a problem to take one Tsukidan to break through from a one-tier martial artist to a two-fold martial artist.

But he didn't expect that he would be able to break through so quickly, Ling Yunfeng guessed that it might be because of the refining of the Heavenly Technique, which has the effect of refining all the energy things, so that the medicinal power in the body can be refined more thoroughly.

"Continue refining!" calmed down the excitement in his heart slightly, Ling Yunfeng secretly said that there was still nearly thirty percent of the medicinal power left in his body.

If he refines the residual energy in his body after refining his own cultivation, Ling Yunfeng estimates that if he divides each realm of a martial artist into three stages, the early, middle, and late stages, if he completely refines the residual energy in his body, his cultivation should be raised to the point where a dual martial artist is close to the middle stage.

Immediately, Ling Yunfeng's palm slowly drew a few strange and graceful arcs in front of him, and then formed a mysterious seal, entering the cultivation state, and soon entered the relentless refining of the medicinal power in his body, and his whole body was gradually shrouded in a strange yellow mang......

"Whew!"

When Ling Yunfeng withdrew from the cultivation state again, it was already evening, and at this time, the medicinal power in his body had already been refined by him, and the aura around his body was obviously much stronger than before, although it had not yet reached the middle stage of a dual martial artist, but it was almost there.

"Well, the harvest is good, let's go back first!Continue tomorrow!" Feeling the changes in his body, Ling Yunfeng smiled slightly, and then called back Xiao Tian and asked him to return to the refining space, and then put away the Nine Dragons refining Tianding and walked out of the cave and walked in the direction of the Ling family.

That night, Ling Yunfeng was still soaking in the blood-colored liquid in the bucket to quench his flesh body, after these few days of tempering, Ling Yunfeng could obviously feel that his physical strength was much stronger, and he estimated that with his current physical strength, even if he resisted the triple martial artist's blow, it would not be much of a problem.

The next morning, when the sky was still bright, Ling Yunfeng got up and said hello to his mother, and then hurriedly ran in the direction of the back mountain, today he also had to refine the remaining two medicinal materials of Zhuji Dan into pills and sell them, in exchange for some money to buy some useful things for his cultivation.

"Why does this kid have to go out every day lately, and all day long when he goes out? Looking at Ling Yunfeng's back, Su Shi sighed slightly.

Not long after Ling Yunfeng left, a shadow appeared outside the small courtyard, a lilac power suit wrapped around the convex and upright body, outlining a graceful and seductive arc, three thousand splashes of ink-like hair were sprinkled on the well-proportioned shoulders, and a few strands of hair fluttered in front of the forehead, invisibly with an elegant temperament.

This daughter is Ling Yunfeng's nominal sister, and she is also the fiancée of the unclear relationship, Ling Xueyan, the adopted daughter of the Ling family, since she felt Ling Yunfeng's invisible changes during this time, she aroused her curiosity.

In addition, after he accidentally peeked at the other party taking a bath yesterday, he always had an inexplicable meaning towards Ling Yunfeng in his heart, so he came here again today, intending to learn more about her younger brother and confirm whether the other party had really changed, or if it was just his own illusion.

Ling Xueyan walked towards the small courtyard with a basket of snacks, and was just about to step into the courtyard gate when a butterfly-like green shadow suddenly burst out from the side.

"Sister Xue Yan, why are you here too?" the shadow came to Ling Xue Yan's side and smiled at her.

"Well, I'll bring some food to my mother. Mengyu, what are you doing here?" Ling Xueyan looked at Qianying beside her and smiled, of course her true purpose was not easy to say, listening to her address the other party, you could know that this Qianying was Ling Mengyu.

"Oh, I'm also here to see Aunt Yu. Ling Mengyu's smart beautiful eyes turned and said with a smile, in fact, she also had the same thoughts as Ling Xueyan in her heart, but it was just difficult to say.

"Huh, Xue Yan, Mengyu, why are you two children here again?" At this moment, a figure came from the small courtyard, and then I saw Su Shi walking quickly from the courtyard.

"Mother, we're here to bring you something. Ling Xueyan smiled at Su Shi and smiled.

"Didn't you just come here yesterday, why did you come here again?" Su said.

"This ......" Ling Xueyan was speechless for a moment, she had just come yesterday, and the purpose was similar to today, but she couldn't say that she was here to see Ling Yunfeng, right?

"Aunt Yu, let's come over and take a look if we haven't had anything to do in the past two days, isn't Aunt Yu welcoming us?" Ling Mengyu smiled sweetly, with a little cunning in her eyes.

"Hmm!" Hearing this, Ling Xueyan breathed a sigh of relief lightly and nodded hurriedly.

"Look at what you say, how could I not welcome these two lovely girls. Su smiled. Then his eyes were a little helpless: "However, it's not the right time for you to come today, I was about to go out to work, and Feng'er had just gone out." ”

"Oh, Yun Feng went out, where did he go?" Hearing that Ling Yunfeng was not there, a trace of disappointment appeared on Ling Xueyan and Ling Mengyu's faces, and they immediately asked.

"I don't know, Feng'er has been a little weird lately, and she goes out all day. Su said.

"Once you go out, it's going to be all day, where will you go?" Ling Xue Yan frowned slightly and muttered in a low voice.

"Madam, I'm going to work, huh, Miss Xue Yan, why are you here?" At this moment, Ling Mo came out of the room and hurriedly greeted the three of them.

"Well, let's come over and take a look at Aunt Yu, oh, by the way, Xiao Mo, do you know where your young master has gone?" Ling Mengyu nodded first, and then asked, she knew that Ling Mo had been very close to Ling Yunfeng since she was a child, and she should know where Ling Yunfeng went.

"Isn't the young master here? I don't know where the young master goes, the young master hasn't been here during the day recently. Ling Mo said.

"Oh. Hearing this, Ling Mengyu nodded slightly disappointed.

"But...... I heard the servant who guarded the backyard say that the young master has been going in the direction of the back mountain for the past few days. ”

Seeing the other party's somewhat disappointed look, Ling Mo hesitated for a while and said, because he knew that these two young ladies had been good to their young master since they were young, and they should not be bad for the young master.

Although Ling Mo didn't know what the young master was doing every day, he also knew that he should do something he didn't want to be known, so if ordinary people asked about his young master's whereabouts, he wouldn't say it.

"Back to the mountain?"

Hearing this, Ling Xueyan and Ling Mengyu both had beautiful eyes, and their eyebrows were slightly furrowed, but they remembered that the day before yesterday, they saw Ling Yunfeng barbecue in the back mountain.

Listening to Ling Mo say this now, Ling Yunfeng may have been in the back mountains for the past few days. So what is he doing in the back mountains? This piqued their curiosity even more.

"Miss Xue Yan, Miss Mengyu, I'll leave first if I still have something to do. Ling Mo said, and then left in a hurry.

"Xue Yan, Mengyu, then I'll go and get busy first, you can just do it, if you want to go in and sit down, go in by yourself. Su Shi said softly.

"Uh-huh, mother, you go. Ling Xueyan smiled slightly.

"Hmm!" Su Shi answered and left in a hurry, she almost had endless work to do every day, so she had to go early.

"Sister Xue Yan, what did you say Brother Yun Feng has been going to the back mountain for a long time lately?" Ling Mengxuan asked with big smart eyes.

"This ...... I don't know. Ling Xueyan said.

"Why don't we go find him?" Ling Mengyu suggested.

"This ...... Not good. Ling Xue Yan frowned.

"What's wrong, let's go. Wait for me!"

Ling Mengyu directly snatched the basket from Ling Xueyan's hand and ran into the small courtyard, placing both baskets on the stone table under a small pavilion in the small courtyard. Then he came out and took Ling Xueyan's hand, who was still standing at the door, and went to the direction of the back door......

In a small cave under a small hidden valley, a dazzling yellow fire illuminates the gloomy cave.

In the center of the cave, Ling Yunfeng was closing his eyes and concentrating, one hand was attached to the wall of a three-legged giant tripod in front of him, a pale yellow flame was burning in the medicine tripod, and a blood-red mushroom-shaped elixir was being wrapped in the blazing flames.

Under the continuous smoke of the flames, a trace of blood-red liquid continued to seep out of the surface of the mushroom, and the mushroom slowly withered.

This blood-red mushroom is the blood-colored mushroom that Ling Yunfeng picked in the red blood lizard's cave last time, and it is also one of the main materials for refining Tsukidan, and at this moment, Ling Yunfeng is starting to refine Tsukidan.

I didn't see Xiao Tian this little guy next to him today, this guy told Ling Yunfeng when he came back last night that he had recently realized that he should retreat and comprehend it, and told Ling Yunfeng not to disturb him until he woke up.

Therefore, as soon as Xiao Tian returned to the refining space last night, he immediately entered the cultivation state, and he didn't wake up until now. Ling Yunfeng naturally didn't dare to wake him up, the other party was in retreat and comprehension, maybe it was at a critical moment, it would be bad if he disturbed the other party.

Although it would be safer to have someone on the side to protect the Dharma when refining the pill by yourself, but this back mountain is very remote, and generally no one will come, so as long as you are careful, there should be no problem.

Just as Ling Yunfeng was immersed in alchemy, two shadows appeared in a quiet small valley in the back mountain, which was where Ling Yunfeng barbecued the day before yesterday.
