Sister Mei was pleasantly surprised: "Great, with this relic, my heart is full of great confidence, and then I will go to develop the elixir!"

"Well, good!" Chen Xun'er was also very happy, completely hiding her worries just now under her smile.

Chen Huo'er was extremely excited, and said innocently: "Sister Mei, do you think there will be a second bone grinding relic in this pile of pus and blood? If so, let's continue to look for it, aren't you more sure?"

Sister Mei was stunned for a moment, then laughed and said: "Impossible, a cave demon should only have a demon bone relic, and it is so difficult to find, there should be none, if you still want to find it, unless you love to kill a huge cave demon!"

"Okay, okay, you can hurry up and develop it, let's take a new look, and then return to the alchemy base to be your protector, 1" Chen Huo'er suddenly felt that he was so naïve, and hurriedly said.

Sister Mei took the two relics, turned around and hurriedly walked towards the alchemy base.

Chen Huo'er wandered around Chen Xun'er and Zi Tiankeng, but still didn't find the third cave demon that crawled out, Chen Huo'er's face was full of anxiety, but Chen Xun'er felt more and more relaxed.

"Senior sister, you don't seem to be in a hurry?" Chen Huo'er suddenly felt that Senior Sister's expression was a little weird, and couldn't help but ask.

"Uh......" Chen Xun'er thought about it, and still told Chen Huo'er her thoughts: "Huo'er, think about it, if a large number of cave demons continue to pour out of this sinkhole, what do you guess the consequences will be?"

"Of course, it's to destroy them one by one and get more bone grinding relics!" Chen Huo'er said.

"And then?" Chen Xun'er continued.

"Then?" Chen Huo'er was stunned: "Then, maybe Sister Mei has really developed a strange elixir, if there is a cave demon again, she can easily restrain it!"

"Look at you, you have said maybe, who can say such a thing clearly? Who knows if Sister Mei can develop it? Even if it is developed, who knows if she can restrain the cave demon?"

"Yes!" Chen Huo'er suddenly realized.

"Also, are you thinking about it, what will happen if a large number of cave demons really come out of this sinkhole?" Chen Xun'er continued to ask.

This time, Chen Huo'er was not in a hurry to answer her senior sister, she looked at the Qiankun bag on her right hand, and said to herself: "It's strange to say, this baby doesn't seem to have the power it used to be!"

"Why don't you say that our internal strength has been damaged a lot and we haven't been able to give full play to the greatest advantage of the Qiankun bag?" Chen Xun'er asked rhetorically.

"That's right, if a large number of cave demons pour out of the sinkhole, not only will the Qiankun bag be unbearable, but even our two sisters will be unbearable!" Chen Huo'er finally figured out the stakes of this matter.

"And!" Chen Xun'er said seriously: "We all agree that the cave demons that crawl out of the sinkhole now are all the demons who slipped through the net after Xiao Jump and Rourou entered the sinkhole, one by two, or five or six, I think this conjecture is right, but once there are many cave demons that crawl out, don't you think our conjecture is ridiculous?"

"Ah, Brother Xiao Jump......" Chen Huo'er was about to cry in an instant, paused, and then said: "That master, she is an old man......"

"Senior sister, don't be afraid, it should be fine, think about it, aren't there only two cave demons crawling out now?

"Yes, yes, cave demon, don't climb out!" Chen Huo'er nervously looked around again, and said worriedly.

"Well, no!" Chen Xun'er said.

"I hope so!"

The two sisters patrolled around the sinkhole for a while, and sure enough, they didn't see the third cave demon continuing to crawl out of the sinkhole, so Chen Huo'er said: "Senior sister, it seems that it's really fine, or we will go to the alchemy base to be Sister Mei's protector, and see if she has developed a new elixir!"

"I think so too!" Chen Xun'er nodded.

The two sisters quickly returned to the alchemy base, and as soon as they arrived at the entrance of the cave, they asked a strong smell.

"I'll go in and take a look, how about you guard the entrance of the cave for a while?" Chen Xun'er said first.

"En!" Chen Huo'er raised the Qiankun bag in his hand and said, "Go and see, I'll give you the Qiankun bag when you go back, you come to guard, and I'll go in and have a look!"

Chen Xun'er smiled and walked into the cave, only to see that Sister Mei was already busy working around those dilapidated alchemy furnaces, and beads of sweat appeared on her forehead. It's really incredible, the two small bone grinding relics can make Sister Mei sweat profusely.

"You're here!" Sister Mei raised her head, looked at Chen Xun'er's strange expression, and said hello.

"Fire son, guard the entrance of the cave, it's okay, I'll come in and see how you have developed!" Chen Xun'er looked at the alchemy furnace, and the strange stimulating smell came from the alchemy furnace.

"This thing, it's so strange!" Sister Mei threw a ball of firewood and grass into the stove at the bottom of the alchemy furnace and said, "Originally, I used a simmer to calcinate, but who knows that I still can't control it, and I watched these two bone grinding relics grow bigger and bigger!"

"The longer you grow, the bigger it gets?" Chen Xun'er became even more curious, and said: "I don't know much about the way of alchemy, have you ever thought about trying it with fierce fire?"

"Normally, no, but seeing the bone grinding relics from a small bead to the size of a fist, I am very anxious, this is not adding firewood, I hope to try it with a fierce fire!"

This time, the flames that were originally burning in the stove suddenly became smaller, and there were bursts of smoke, and the entire alchemy base was instantly choking with the smell of smoke!

"......Forehead" Chen Xun'er saw that things were not good, and hurriedly stretched out her right hand, the dantian exhaled, and a soft wind blew out from the tiger's mouth, directly to the bottom of the alchemy furnace, and in an instant, the flames were blazing!

"Okay, it's bigger!" Sister Mei was stunned for a moment, and said very excitedly: "It's good to have internal strength to cultivate!"

Chen Xun'er once again highlighted her true qi, and the air flow that came out of the tiger's mouth was not big or small, just enough to make the flames at the bottom of the alchemy furnace burst into flames.

"Huhuhuhu......" A wonderful voice rang out.

"Wait!" Sister Mei first noticed that something was wrong, she motioned for Chen Xun'er to stop, but she quickly stood next to the alchemy furnace, looked into the small hole, and was instantly surprised: "It's not good, how can this be?"

"What's wrong?" Chen Xun'er was very puzzled, could it be that she used her internal strength to help fan the flames, which backfired?

"It's terrifying, the two relics have actually fused together, and they have become the size of a human head!" Sister Mei said in surprise.

"Someone's head is so big? Didn't you just say it's as big as a fist?" Chen Xun'er knew that something big was wrong: "Are there any other bad things that will happen?"

"Probably not!" Sister Mei looked at the alchemy furnace and said, "It seems that as long as it doesn't increase its vitality, this thing won't continue to grow!" Sister Mei's eyes didn't leave the alchemy furnace.

"That's great, let him refine it slowly!" Chen Xun'er said.

Sister Mei nodded, continued to pay attention to the fire in the alchemy furnace, and completely ignored Chen Xun'er beside her.

Chen Xun'er only felt that she was a little redundant, so she turned around and walked out of the cave again.

As soon as she arrived at the entrance of the cave, Chen Huo'er couldn't wait to ask, "Senior sister, what's wrong?"

Chen Xun'er added fuel and vinegar and said: "The bone grinding relics are really extraordinary, two small bone grinding relics, under the refining of the alchemy furnace, when I first entered, it was only the size of a fist, and then Sister Mei thought that the fire was very small, so I used my internal strength to help fan the flames, this is good, the two demon bone relics instantly merged into one, and they became the size of a human head, it seems that that thing is still very magical!"

"I'm going to take a look, too!" Chen Huo'er hurriedly handed the Qiankun bag in his hand to his senior sister, then waved his hand and walked towards the cave.

Sister Mei was constantly busy, checking the fire in the alchemy furnace and the changes in the demon bones, for a long time, then she straightened her waist, took a breath, and inadvertently looked back and saw that Chen Huo'er could only be behind her, and was startled: "Why are you? I clearly remember that your senior sister came in? Am I enchanted?"

"Haha, no, my senior sister did come just now, she saw that you were very focused, went out, and then I came in again to take a look!" Chen Huo'er looked at the alchemy furnace, at this time, the flames under the alchemy furnace were already very small, but the inside of the alchemy furnace was red.

"So that's the case, just now, I can't help but fantasize, I thought I had a problem again!" Sister Mei said self-deprecatingly.

"Fantasy?" Chen Huo'er thought that how could he fantasize, so he asked, "What are you fantasizing?"

"Hehe!" Sister Mei smiled strangely and said, "I fantasize that I have become a very powerful female demon, and no species is my opponent, including Ma Xiaoyue and Rourou, but what caused me to become a super female demon was the fireball in this alchemy furnace!"

"Huh?" Chen Huo'er was stunned for a moment, and his eyes looked into the alchemy furnace.

Sister Mei carefully opened the lid of the alchemy furnace, and sure enough, the two demon bone relics actually fused into a fireball the size of a human head, which can make people think about it at a glance, no wonder Sister Mei has fantasies!

"Poof!" After Sister Mei opened the lid, the fireball miraculously came out of the alchemy furnace and suspended in the air!

"What's going on?Is this how it's refined?How can you control it?Can you drive away other cave demons?" Chen Huo'er asked a series of questions.

Sister Mei shook her head, her eyes stared at the fireball, and the fireball seemed to be stunned, far away from her!

The air froze instantly, and Chen Huo'er suddenly felt that something was wrong!

Sure enough, after the fireball was suspended in the air, after a few minutes of immobility, it automatically gradually thinned, turned into a fiery red flame, and pounced towards Sister Mei's mouth. And Sister Mei opened her mouth and let the flames of the fireball enter her mouth. All this happened in front of Chen Huo'er!

Chen Huo'er couldn't believe that this was true at all, but seeing that the flames that had been transformed entered Sister Mei's mouth one by one, Sister Mei was as happy as if she was smoking a delicacy!

"Sister Mei, what's wrong with you?" Chen Huo'er became anxious, would there be any bad results in this way?

Sister Mei didn't react, and her mouth didn't close until the fireball suspended in the air was sucked by her and left nothing!
