At this time, Shen Cheng, who had already turned on the spiritual eye technique, saw the light stone on the roof of the stone room, exuding a dark green glow.

On the wall on the side of the stone chamber, a large amount of green yin qi gushed out, pouring down layer by layer like a waterfall. The floor was like a small dark green pool that was knee-high, and the moment the stone door was opened, the yin qi gushed out like a tide, freezing so cold that Shen Cheng's legs were numb!

But other than that, Shen Cheng didn't find anything else in the stone chamber. It doesn't seem that as he just expected, there is a strong enemy entering the cave!

Shen Cheng pondered for a moment, wondering what was in the walls of this stone room! In just half a month of his retreat, such a big change had taken place in this cave mansion, would this matter have anything to do with the master who had not returned from the mountain?

He was pondering whether to wait for the master to come back before making plans, but Shen Cheng saw that the thick green yin qi pouring down from the stone wall was slowly decreasing at a speed visible to the naked eye.

In just a moment's breath, the stone room and the walls of the stone hall were completely gone, and there was no longer a cold air coming out.

And the even more bizarre thing is still to come, the yin qi accumulated in the entire cave mansion was actually pumped back by the cave wall at this moment, and the speed was a few points faster than the previous gushing out.

After about another meal, there was no trace of cold green air in the entire cave, and the biting cold feeling from before disappeared, and the light stone on his head returned to normal at this moment.

Today, these strange things happened one after another, making Shen Cheng lose his judgment a little! It seems that he needs to get to know this cave mansion where he has lived for three years!

He stared at the wall where the Yin Qi gushed out the most just now, and observed for a while, but he couldn't see anything wrong!

After a while, Shen Cheng closed the door of the master's stone room, took back the golden snake sword, walked to the stone table in the stone hall and sat down, thinking about the strange thing just now!

At this moment, there was a sound of footsteps from outside the cave, and Shen Cheng was sure that it was the master who came back as soon as he recognized it, and he couldn't be more familiar with the footsteps!

Shen Cheng was overjoyed in his heart, and just wanted to get up to greet his master, but when he stood up and took one foot, he stopped again, and a trace of a smile on his face froze!

"Should I tell my master about this? If Master doesn't know about this matter, it's okay, just tell him the old man to find a way to deal with it! What if Master knows, and this matter is still a secret of his? Or maybe Master already knows that he has discovered this secret and is waiting for him to tell the truth, but he doesn't say it......" In just a few breaths, several thoughts had flashed through Shen Cheng's mind, and he couldn't make up his mind after thinking about it repeatedly!

In a moment, the little old man had already opened the stone gate of the cave, and Shen Cheng didn't have time to think about it anymore, so he hurriedly greeted him and said, "Master, are you back?"

"Hehe, stinky boy, it seems that your harvest in the past half month is really not small! You are already a monk of the fourth layer of the Qi Melting Stage? Yes, look at what Master has brought back to you this trip. The little old man who had just entered the cave had already seen the change in Shen Cheng's cultivation, and while praising happily, he shook his hand and threw a gray object towards Shen Cheng.

"Storage bag?" Shen Cheng took this item into his hand and took a closer look, and shouted out in surprise. This is something that Shen Cheng wanted to get a long time ago!

The little old man seemed to be in a very good mood when he came back this time, walked to the stone table and sat down, called Shen Cheng over and said, "The teacher knows that you have long wanted to have a storage bag." I thought it would take some time for you to be able to use this thing, but I didn't expect you to break through the bottleneck and advance to the fourth layer so quickly in the few days that you have been out for the teacher. That's just the right time to give you this storage bag, and now you should have enough spiritual power to use it! ”

"Let's start with how to put things in storage bags. You only need to use your spiritual power to control the storage bag first, and then lock the spiritual power into the items that need to be loaded through the storage bag......" The little old man said as he demonstrated to Shen Cheng.

After only a while, Shen Cheng learned the essentials of using storage bags. This will be on the storage bag, take out his golden snake sword from the storage bag, look at the gray bag in his hand over and over again, and suddenly remember something: "Master, how many things can this storage bag hold? What if it is broken?"

"Hehe, no, try to cut it with your golden snake! As for how many things can be contained, it should not be difficult to fit this stone table and a few stone benches in front of you. The little old man twisted his beard and smiled at Shen Cheng's happy appearance.

Shen Cheng thought about it, then took out the golden snake sword and gently cut it at the bag, and sure enough, it was fine. He gradually increased his strength, and cut the bag several times, leaving only a few marks on the bag, and there was not a trace of damage.

"Eh, you don't have to try it! As long as you don't use spells to forcibly destroy it, you can't destroy it with your cultivation and that golden snake sword!" the little old man looked at Shen Cheng angrily and funny.

"What a good thing. Shen Cheng thought happily. In fact, how did he know that most of these storage treasures are very tough, and they are also resistant to ordinary fire and water, as long as they are not extremely powerful means, they generally can't help storage magic weapons.

"Apprentice, what has happened in the past few days when the teacher has been away from the mountain?" Seeing that Shen Chengzheng was satisfied with the storage bag tied to his waist, the little old man asked.

Shen Cheng was shocked when he heard the little old man's question, but his face was not flustered, and he replied respectfully to the little old man: "It's not a big deal, it's just that on the day the master went down the mountain, the Ling seniors of Taoye Island were worried about the master, and the special Miss Ling Xiang came over to inquire." ”

"Oh, how did you answer her? Oh, don't stand there, come and sit down. ”

"Oh, the disciple told her, I only know that your old man will go out for about ten days and half a month, and I don't know anything else!" Shen Cheng sat down beside the master and replied.

"Well, I know! Tomorrow I will go to Peach Leaf Island for a trip. Speaking of this, the little old man put on that mysterious appearance again, raised his eyebrows and said, "That girl came to the mountain, didn't you invite someone to sit in the cave?"

Shen Cheng was helpless in his heart! What are you afraid of, this bad old man wants to know something!

"Ah, yes, please...... Miss Ling entered the cave and sat ...... Come on. Also, I also exchanged my cultivation experience. Oh yes, Miss Ling also looked at my cultivation exercises, and said that she was actually practicing the "Taiyu Gong"! She also said that my cultivation was much faster than the "Taiyu Gong", but the disciple remembered that the master only said that it was a little faster! The disciple was puzzled and wanted to wait for the master to return to the mountain and ask you for a lesson or two!" Shen Cheng, who had already stumbled when he spoke, suddenly changed the topic as if grasping a life-saving straw.

"Haha, this one! The understanding of the cultivation of the exercises varies from person to person. No matter who says you don't have to take it too seriously, whether it's fast or slow, whether it's suitable for your cultivation is the most important thing. The little old man saw that Shen Cheng was embarrassed to mention him and Ling Yatou again, so he didn't ask any more.

"Got it, Master. Master, the disciple had just broken through the fourth layer the day before yesterday, and had been meditating in the cave for more than ten days, and was about to go out to exercise his muscles and bones at this time. Shen Cheng was afraid that this little old man would ask about those things that he was ashamed to talk about, so he wanted to find a way to slip away first.

"Well, let's go, let's go. The little old man waved his hand with a smile.

Shen Cheng stood up and bowed and walked out of the cave.

At this time, it was almost noon, and the mountains and forests were warm, and Shen Cheng looked back at the direction of the cave with strange eyes, thinking about the strange situation last night! Will the same thing happen again tonight?

And the little old man was also sitting in the stone hall of the cave at this time, holding a fly and twisting his beard, squinting at the direction of his stone room, thinking about something!
