Yu Xia remembered that Yun Nianchu gave her this pill at the beginning, and seemed to mention that she should not overdose within a day, she did find that this pill was different from ordinary qi tonifying pills, and the effect was even worse, when she had stunned those people who had lost too much vitality, taking her pill immediately eased up, and the vitality in her body also recovered as before, if it was replaced with He'an Tang's qi tonifying pill, it might be several pills that could keep her moving as usual without being unconscious.

She only regarded Yun Nian's initial medical skills as very good, and the elixir she refined was several times stronger than that of He'an Tang. Therefore, she cherished these pills very much, just now those errand soldiers fainted, she just gave the ordinary qi tonifying pill, and this one for Baili Yexi, she really hesitated for a long time before taking it out.

It's just that Yun Nianchu obviously gave her Taiyuan Dan, why do you want to say that it is an ordinary qi tonifying pill?

Yu Xia was a little confused, her brows were slightly locked, and when Baili Yexi saw that she was thinking about things wholeheartedly, she coughed lightly and woke up Yu Xia who was in deep thought.

"I said, your Taiyuan Pill is better than ordinary medicine, it's not something that your earth bun can have, right? Where the hell did you get that? ”

Yu Xia didn't want to pay attention to him, "You hurry up and work, don't grind." ”

She still feels sorry for the Taiyuan Pill that she just gave out, and gave it to Baili Yexi, which is really a cow chewing peonies and destroying heavenly things......

"I've never seen anything good, little family." Baili Yexi glanced at her disdainfully, but still according to what she said, she worked honestly, and after a while, she brought back a bundle of straight and appropriate thickness of branches.

Yu Xia tried the simple wooden stick made by the Hundred Miles of Night Light and nodded with satisfaction.

Although Baili Yexi listened to her command and got these sticks back, she didn't understand her plans, so she leaned back to the tree and stared at her intently.

I saw Yu Xia take out a few thin and somewhat curved stone chips from the side, sharpen the end of the wooden stick with a dagger, put the stone chips on it, and dug a small hole in the wooden stick above the stone chips, found a branch of similar thickness to pass through the hole, and firmly fixed the stone chips at the end of the wooden stick.

Baili Yexi looked at the movements of Yu Xia's hands curiously, and finally couldn't help but ask, "What are you doing?" ”

Yu Xia's hands kept moving, and he didn't raise his head when he asked, "This is called Leiyun, our ancestors didn't use iron or bronze tools before, they could only use stones or bones to make simple tools, in order to do agricultural mulberry, "Zhou Yi" There is a record that Shennong's 'chopping wood for the plow, kneading the wood for the plow, the benefit of the plow, to teach the world', you are also a person in the Xuanmen, how can you not even know this." ”

Yu Xia's last sentence was purely casual, without the slightest irony, Baili Yexi was a little unconvinced when he heard it, of course he knew the record in "Zhou Yi", but he hadn't seen it with his own eyes, and he didn't remember it for a while. Thinking so in his heart, he unusually didn't choke with Yu Xia, and honestly observed her every move without saying a word. When Yu Xia finished making another one, Baili Yexi also took a wooden stick and followed Yu Xia's steps.

The stone flakes are not as strong as iron and bronze tools, they are more than hard but not tough, and they are easy to break, so the two of them made a few more and used all the wooden sticks prepared by Baili Yexi.

Looking at the simple farm tools on the ground, Baili Yexi felt a great sense of accomplishment, and he didn't care about wiping his hands with a handkerchief, so he took a handful of plows and dug up the soil.

After all, the two of them are people with cultivation, and they don't have enough strength but have vitality to make up for it, and they even have more stamina than ordinary strong people, and it is not easy to run out of strength and be unsustainable. The two of them dug up the soil for half an hour, dug up six rakes, and finally saw the whole picture of the coffin by the faint light of the torches.

This coffin is vermilion, carved with strange patterns, some dilapidated, and two sealing charms are pasted on the coffin. One looks old, it should have been pasted when he was buried, Yu Xia glanced at the talisman by the light of the torch, the light was dim, and he couldn't see it clearly, but he felt that its rune pattern was a little weird. Another talisman is relatively new, it should have been pasted by the monk who did things when the grave was moved, Yu Xia glanced at it casually, it should be the most ordinary requiem talisman, and it has no other effect. As for the evil charm that Feng Kun tried to paste before, he didn't put it on at all, so naturally it wasn't on this coffin.

"This coffin, there is no evil qi at all, not only that, but there is no yin qi ......" Baili Yexi frowned, and his face was no longer as relaxed as before.

The black gas under the mountain is billowing, like substance, but this coffin is ordinary. It is this ordinariness that makes it more and more difficult. If it was an ordinary coffin, buried in that evil realm, the corpse inside should have changed a long time ago, and with that level of evil qi, after being buried for a long time, maybe there would be a corpse king.

"Huh?" Yu Xia noticed something unusual, pointed to a nail in the coffin and said, "Look at this nail." ”

Baili Yexi leaned over and saw that it was an ordinary copper nail, and there was no difference, so he asked strangely, "What's wrong with this nail?" ”

Yu Xia didn't look at him, and checked all the sealing nails on the coffin again, "These nails are very new." ”

Hearing Yu Xia say this, Baili Yexi also noticed that something was wrong, looking at this coffin, the skin is peeling off, and the wood is also a little rotten, it makes no sense that this coffin nail is still new......

The two glanced at each other, and there was a hint of jealousy in each other's eyes.

"Let's ...... Open the coffin again tomorrow? Yu Xia asked.

Originally, she thought that it was a ghost, and it would appear at night, but this was not the case, this coffin was really a little weird, and it was far from what she thought before, plus Feng Kun suffered a loss here last time, she didn't dare to hold it up, for the sake of safety, it would be better to talk about it tomorrow.

Baili Yexi had no objection, looked at the coffin that was dug up, and asked her, "What about this ......coffin?"

Yu Xia didn't raise his head, picked up a pole and began to dig up the soil again, "Of course it's buried back." ”

Baili Yexi saw that her little girl was working, and she naturally couldn't shirk it, so she could only sigh helplessly, "Yes, I was busy working in vain, I knew I wouldn't dig the coffin tonight......"

Yu Xia was in a good mood, and only said, "I'm sure it's not a ghost, and it's not all fruitless." ”

The two chatted for a long time and buried the coffin. This time, Baili Yexi really couldn't stand his gray face, but it was difficult to find even a clean water source in this mountain, so he had no choice but to follow Yu Xia down the mountain awkwardly.
