Mu Ning and Zheng Xuan carefully studied the secret letter, and according to the location of the secret letter pointed out, they searched carefully, and successfully found the secret realm blueprint, which was leather, and after being wrapped layer by layer, it was very intact.

Mu Ning and the others unfolded the drawings and began to study the terrain drawn on the drawings, at that time, Mu Ning and Zheng Xuan kept complaining, what is this drawing, there is no chapter, and it is not marked what the terrain is, it is just a cluster of lines, which makes people dazzled, but for the strong curiosity in her heart, Mu Ning had to patiently continue to study the line patterns on the map, and compare them with the topographic drawings of Liuyun Valley one by one.

Mu Ning slowly calmed down his irritable mood, carefully studied the drawings of the secret realm, looked at and felt that the dots of line patterns in this drawing were so familiar, as if he had seen them somewhere, Mu Ning slowly searched in his mind, these complicated patterns must have been seen by himself, otherwise he would not have such a familiar feeling.

Mu Ning "ah", she remembered, and hurriedly took out the twin jade pendants, no wonder they were so familiar, the original line patterns on the drawings were exactly the same as the patterns on this jade pendant, Mu Ning put the jade pendant on the drawing, just right half of the pattern, the other half of the line pattern is not the jade pendant of her brother of the soldier king, Mu Ning was very happy, and laughed all of a sudden, Zheng Xuan and Shen Yu looked at Mu Ning and suddenly smirked, knowing that this girl had found the doorway.

Mu Ning printed all the positive and negative patterns of his jade pendant on paper, and then after processing, the pattern of her brother of the king of soldiers also drew the pattern of the jade pendant, including the word "Miaoyu" on it, and then put the two rubbings on the secret land drawings back and forth, repeated comparisons, and then used the terrain drawings of Liuyun Valley to verify, and finally found the location of the secret realm, Mu Ning's mood became more and more excited, and he thought that he was definitely not sent to this era like winning the lottery. There must be some major reason for this, and she must solve this mystery anyway, otherwise she will really have trouble sleeping.

When Mu Ning and the others came to the location of the secret realm, they suddenly felt that their heads were big, how could they find it, this is a whole mountain, but what makes them strange is that the other mountains in Liuyun Valley are all lush and colorful, but why is this mountain not a single grass growing, is there any mysterious substance in this mountain that makes it so?

Mu Ning and the others began to look for the entrance to the cave, but the guards searched the whole mountain bag and the mountain, and they did not find a single opening; Mu Ning thought about it, the powerful valley lord who sealed the secret realm might leave some strange signs for his successors to open this secret realm, so Mu Ning asked everyone to look for stones or imprints with strange signs, and after careful search and confirmation several times, he finally identified a boulder full of potholes and holes of different shapes, and there were thousands of small holes on this boulder, and he was really anxious to look at, and Mu Ning didn't know whether to admire or be annoyed by the powerful valley lord.

Mu Ning looked left and right, up and down, up and down, up and far, and really let her see the doorway, this boulder as a whole is a teardrop-shaped, just like the modern red jade pendant of hers, that pendant has now become the pendant of the purple gold red jade hairpin.

Mu Ning took out the purple gold and red jade hairpin and looked at Zheng Xuan: "Is it okay?" Zheng Xuan had already seen the problem, so he smiled and said to Mu Ning: "Now that this jade hairpin is yours, you can make a decision." Mu Ning heard Zheng Xuan say this, Mu Ning smiled "hey", and took the red jade hairpin to the boulder to compare seriously, the hard work paid off, and there was a small hole in the lower left corner of the boulder that was exactly the same as the red jade pendant.

Mu Ning swallowed his saliva, took the red jade pendant off the purple gold red jade hairpin, and gently put it into the small hole, but there was no movement, Mu Ning gritted his teeth and pressed the red jade pendant hard, and immediately heard the rumbling vibration of the mountain, Zheng Xuan quickly pulled Mu Ning up and left the mountain quickly, and the others also quickly left the place, but although the mountain made a rumbling sound, there was no sign of collapse.

After a while, the rumbling stopped, and I saw that the boulder slowly separated from the middle to form a hole, Mu Ning jumped up happily, grabbed Zheng Xuan's arm and shook it vigorously a few times, Zheng Xuan and Shen Yu finally breathed a sigh of relief, and those who included the guards were even more relieved, it seems that the next time can easily pass a good time, no need to be commanded by Mu Ning to run around the mountains, Liuyun Valley no longer needs to be tossed wolves and rabbits, chickens and dogs, Mu Ning's "combat effectiveness" is too strong.

Zheng Xuan instructed everyone to light the torches, let Mu Ning follow him, and then took the lead into the cave, Mu Ning They walked cautiously in the passage of the mountain, seeing that the torches did not change color, the flame did not become smaller, Mu Ning was relieved, this cave is not a closed space, there should be air circulation, and they will not have the problem of lack of oxygen when they go deep into the cave.

Mu Ning and the others walked along the not too wide passage for a long time, when suddenly the front suddenly opened up, and a huge cave appeared in front of them, and everyone was pleasantly surprised. Mu Ning and the others finally walked into the cave, everyone held torches high and looked around, there was nothing empty inside, but this cave was definitely artificially carved, very large and wide, very high, the walls were polished smoother, and the ground was paved with smooth stone slabs, this was really a big project in ancient times, and it was really a tyrannical thing to be sealed like this for hundreds of years.

Suddenly, someone shouted: "Look, what is this, it's red." Mu Ning and Zheng Xuan walked together in the direction of the sound, there was the middle of the cave, I saw that there was a pool, the shape of the pool was also droplet-shaped, the liquid in the pool was red, bright red as blood, the blood pool in Mu Ning's dream, the blood pool in his heart, the blood pool that could allow him to travel back to the modern era actually appeared here, is it possible to go back to see his parents, mothers and brothers by jumping down。。。。。。

Mu Ning suddenly felt that he was being pulled and fell into an embrace, it was Zheng Xuan. Just now, Zheng Xuan saw that Mu Ning seemed to be tempted by something, his eyes were empty, and he walked towards the edge of the pool step by step, he shouted Mu Ning twice but didn't respond, he could only pull Mu Ning back, Zheng Xuan looked at Mu Ning worriedly, and stroked her hair with his hand: "Girl, what's wrong with you?" Mu Ning has come back to her senses now, and she rubbed her hair a few times on Zheng Xuan's palm: "It's okay." ”

"And said it's okay, if I don't hold you, you're going to fall into that pool of blood." Zheng Xuan said with a deliberate straight face. Mu Ning heard a "huh": "How do you know it's a pool of blood?" Zheng Xuan saw that Mu Ning's expression had recovered, and said with a smile: "The things in that pool are bright red and red, like blood, what's wrong with calling it a blood pool." ”

When Mu Ning saw Zheng Xuan say this, he knew that he was in love, he was a soul crossing, even if he jumped into the blood pool now, he couldn't return to the modern era, plus the material in the blood pool was still unknown, if the current body was damaged, it would be too sorry for the world to love his family.

After Mu Ning returned to the medical castle, he immediately went to the valley master Guan Yufei and asked him about the blood pool, but Guan Yufei couldn't say clearly, it had never been opened since the Liuyun Secret Realm was sealed, let alone him, even the dozens of generations of Liuyun Valley Masters before him had never seen what it was like in the secret realm, what he knew was that word-of-mouth sentence, he had already told Mu Ning about them last time. Mu Ning saw that he had no clue about the matter, so he no longer insisted on it, and it was only a matter of time before this matter would be figured out.

Mu Ning saw that the matter of Liuyun Valley was over, so she was ready to set off to return to the capital, it had been more than half a year since she came out, and her relatives and friends should miss her very much; Shen Yu didn't set off with Mu Ning and them, he hadn't seen his master for many years, he wanted to get together with his master more, and the toxins in Mu Ning's body had been completely removed, so he didn't need to follow him all the time.

Mu Ning now also has a good medical skill, and Shen Yu taught the Liuyun secret technique to Mu Ning with the approval of his master Guan Yufei, which made Mu Ning both surprised and grateful, if he hadn't met Shen Yu, he might have been accompanied by illness in this life, and Shen Yu also carefully taught himself medical skills, and now he even taught himself the Liuyun secret technique, which is a secret technique that only the valley master can learn, not to mention that he is not a disciple of Liuyun Valley.

So, Mu Ning offered to marry Shen Yu as a brother and sister, which made Shen Yu happy; Shen Yu has always wanted to accept Mu Ning as an apprentice, but Zheng Xuan just refused to agree, for fear that he would be a generation shorter than Shen Yu, but now it's okay, it was the little girl who offered to marry her as a brother and sister, see how you Zheng Xuan objected. Shen Yu shouted "brother-in-law and brother-in-law" to Zheng Xuan, Zheng Xuan was both happy and depressed when he heard it, he was happy that Mu Ning did not refute the "brother-in-law" in Shen Yu's mouth, and he was depressed that he was still a head shorter than his friend. Zheng Xuan was already quite scared of Shen Yu, but now Shen Yu has the title of "eldest brother", alas, this day is simply unbearable.

Small Theatre:

Zheng Xuan: Girl, why do you want to marry Shen Yu as brother and sister?

Mu Ning: Shen Yu is very good, isn't it?

Zheng Xuan: Girl, you don't know, Shen Yu usually bullies me, makes me diarrhea for a while, and makes my hands swollen for a while, but now that he and you are brothers and sisters, he will even change his ways to bully me.

Mu Ning: Shen Yu bullied you? But no matter how I look at it, you did it yourself.

Shen Yu: My sister is right, he did it himself.

Zheng Xuan: 。。。。。。

This time, Zheng Xuan couldn't help but pounce on Shen Yu: I just won't do it, what can you do to me.

Mu Ning couldn't help but smile, not bad, knowing that mistakes can be changed, and being good is great.

Shen Yu was depressed, the medicine for swollen hands was ready, but you fluttered.

Zheng Xuanse, the girl really feels the most sorry for herself.
