Deep in the Qilian Mountains, in front of a stone wall on a cliff, under Sun Simiao's efforts, a large hole was actually revealed in the stone wall.

Who would have thought that a big hole could appear here? It is hidden so deeply!

Even Luo Zhang was amazed by this, and secretly thought that the martial arts of later generations were not completely fabricated. Isn't this scene often seen in martial arts of later generations?

Under the leadership of Sun Simiao, everyone walked into the cave.

The cave is very wide, and it doesn't feel too depressing when you walk in. After everyone enters, the stone walls on the left and right light up one after another, illuminating the path forward.

After walking for about half a cup of tea, I saw a glimmer of light appearing in front of me. It was obvious that the exit was right in front of me.

When everyone walked out of the cave and saw the scene on the other side of the rock wall, they couldn't help but be shocked by what they saw.

Flowers blooming, birds singing and flowers fragrant, and vegetation lush, this is the scene before everyone's eyes.

Who would have thought that there could be such a paradise in the Qilian Mountains?

"Don't run around, I'll get something and leave!" Sun Simiao ignored the shocked people, but without saying a word, he walked straight towards a few wooden houses not far ahead.

Obviously, that is Sun Simiao's daily residence.

Luo Zhang looked around. It was obviously an inner valley. There were no roads on all sides, but only hundreds of meters high rock walls.

The valley is not big, but it is about the size of two football fields.

The layout of the entire valley has obviously been carefully designed by Sun Simiao. The left side is mostly covered with lush vegetation and trees, while the right side is planted with various medicinal materials, densely packed all over the ground.

It is said that medicinal plants should be planted on the left side, but Sun Simiao did not plant them. Through observation, it turns out that the left side is shady, while the right side is sunny. Obviously medicinal plants also need sunlight and rain to be more suitable for growth.

From time to time, Luo Zhang could see a few snow-white little rabbits darting in and out of the trees on the left. It seemed that Sun Simiao was also bored and actually used rabbits as pets to pass the time.

Not long after everyone was observing the place, Sun Simiao came back carrying a medicine box.

Wu Shaobin had sharp eyes and hurriedly stepped forward to take over Sun Simiao's medicine box. He was a great master. How could he let Dr. Sun do such a thing of taking things?

In this regard, Sun Simiao did not object and directly threw the medicine box to him.

"Okay, we've got the things. Let's go. You kid, don't fool me. Don't let me go to your place without something delicious to eat! I won't show mercy to you then!" Sun Simiao stared at Luo Zhang closely and said.

.

"Well, how could I deceive you? If there is no delicious food, you can hit me and scold me!" Luo Zhang laughed. He also saw that Sun Simiao was joking with him and was not serious at all. Naturally, he didn't either.

Will take it seriously!

After walking out of the cave again and looking at the tightly closed rock wall, everyone sighed at the magic of nature. It was really eye-opening for them to have such a boundary!

"Stop looking, I see you can't get in either. You can't push away that rock wall if you want! Let's go, it's getting late. I'm afraid we won't be able to go to Chang'an today. We still have to go to the secret cave.

Stay inside for the night." Sun Simiao looked at the eyes of everyone staring at the rock wall and couldn't help but said, obviously, there is some way to open this rock wall, otherwise Sun Simiao would not have brought everyone here so generously, that is

With absolute confidence, no one can get in.

Luo Zhang was thoughtful. To be honest, he really wanted to study how this rock wall was opened to see if it was different from what was written in later generations. However, this is someone else's lair. If you study this, you will definitely be misunderstood.

So this idea can only end in vain.

The way back was naturally much easier. Luo Zhang chatted with Sun Simiao while walking, and he seemed to be very familiar with him.

"Mr. Sun, have you stayed in Qilian Mountain for so many years?" Luo Zhang asked curiously.

"No, I occasionally go out for walks. I have been to all parts of the Tang Dynasty, but the Qilian Mountains are better. No one will disturb me, and there will be no war!" Sun Simiao said bluntly.

Luo Zhang nodded, it's true. There are jackals, tigers and leopards here. Ordinary people can't go deep. It makes no sense for people with high cultivation level to come here. As long as the army will not come here, so for so many years, the Qilian Mountains have been very...

The peace and tranquility, I'm afraid this is the reason why Sun Simiao chose to settle here.

As if he thought of something, Luo Zhang spoke again: "Mr. Sun, there is something I wonder if you know about?"

"What?" Sun Simiao turned around and looked at Luo Zhangdao!

"It's just an iron lump. Once it's lit, it will explode. I've seen a lot of it in the Tiger King's lair before. Did you throw this away?" Luo Zhang asked. This problem had troubled him for a long time. Now he caught it.

When you come to Sun Simiao, you will naturally have to answer some questions!

"Iron lumps? Found them in Wang Hu's lair?" Sun Simiao blinked and asked in confusion.

"According to what Wang Hu said, he picked up a lot of these things around his lair." Luo Zhang explained again.

"I have never seen this thing, but according to what you said, it seems a bit like the kind of thing made by the alchemist of the Great Qin Dynasty." Sun Simiao touched his beard and said slowly.

"Yes, it's that thing. I asked people about it, and others said the same thing!" Luo Zhang nodded.

"No, I didn't throw this away. I've never even seen it!" Sun Simiao denied.

"Not you? This is a bit strange. There are still people who know medicine and alchemy in the Qilian Mountains?" Luo Zhang asked doubtfully.

"People who know pharmacology? People who know how to make alchemy? This..." Sun Simiao seemed to have remembered something, and he couldn't help but ponder.

Seeing this, Luo Zhang was stunned and said: "Is there really such a person?"

"If you say so, there really is such a person, and he can really do such a thing. However, this person has a weird personality and is moody. It's better not to inquire about him, let alone meet him. Remember this!"

Sun Simiao warned.

These words made Luo Zhang stunned. Sun Simiao could be said to be the strongest person he had ever seen. But even if he said this, one could imagine how perverted the person he was talking about was, and he could still create gunpowder.

, this person should be called a freak, and Luo Zhang couldn't help but think of those scientific madmen in later generations, fearing that this person might be like this.

Although he was curious in his heart, his life was still important. It would be right to listen to what the old man said. Luo Zhang did not want to interact with scientific madmen. Those kind of people were all lunatics and psychopaths.

After walking all the way for more than an hour, Luo Zhang and the others finally returned to Wang Hu's lair. At this time, the sky had darkened. Sure enough, as Sun Simiao said, there was no way to go back today, and they could only stay in Wang Hu's home.

Stayed in the old nest all night.

Different from his mood when he came, Luo Zhang was really happy this time. He found Sun Simiao and invited him back. This trip can be said to be a success.

A celebration was naturally inevitable. Luo Zhang once again secretly exchanged a lot of good things from the system, not only shelducks, but also oysters and other items. Even Maotai Luo Zhang exchanged some for Sun Simiao to taste, and got

Sun Simiao praised him greatly, praising Luo Zhang for not lying to him, and he also strengthened his determination to go to Chang'an with Luo Zhang. After all, it was a bit boring for him to lead him alone in the mountains, and he had to go out for a walk every year, so he went with Luo Zhang.

Likewise, there are still people waiting for him to eat and drink, so why not do it.

To this, Luo Zhang raised 10,000 hands in agreement, saying that he would be responsible for food and drink, including wine, and open drinking. This made Sun Simiao even more happy.

There were not many people in the Tang Dynasty who were not good at drinking. If they heard that there was wine to drink, they would still drink it openly. Who would be unhappy? Even Sun Simiao, who had extraordinary medical skills, could not avoid this temptation.

A careful banquet can be said to be a feast for the guests and the host, but the result is that they lie down and fall into a deep sleep before midnight.

Fortunately, there were quite a few people here this time, and not all of the Eighteen Riders were drunk, so it was enough to arrange for people to stay on duty at night.

They slept until almost noon the next day, when Luo Zhang and others got up from their sleeping bags. They were so happy last night that they drank too much.

The lunch was also very sumptuous. Early in the morning, Wu Shaobin took his people into the mountains and hunted a lot of pheasants and roe deer. After Luo Zhang roasted them, everyone almost bit off their own tongues after eating them. They couldn't pass up the delicious ones.

When Luo Zhang and his party came to the gate of Chang'an City leisurely, it was already afternoon, but Luo Zhang was not in a hurry. This was mainly to take care of Sun Simiao. No matter how strong he was, he was an old man after all, and he was not in a hurry.

If you're in a hurry to have a baby, it's okay.
