To Teacher Xia's surprise, Mu Yunyun didn't show more frustration, and she was thinking about it when she talked about the origin of the artillery.

Mu Yunyun had felt that the word artillery was too advanced before, and when she heard that it was a relic found in the mountains, she couldn't help but feel a sense of absurdity in her heart.

A small person like her can pass through, is it hard to guarantee that before her, there will be a real genius scholar who passed through and used modern knowledge to make artillery?

"Teacher, when you found the artillery, was there anything else around, such as a codex or something?"

Teacher Xia thought she was talking about the formula of the ammunition, and shook her head regretfully, "The people who developed the artillery either didn't want it to come out, so they buried it in the mountains, and the stone was only engraved with the word 'peace', and the strokes were very upright, like a child learning to write, but it looked like a child's penmanship, not like it came from a child's hand." ”

If the strokes are correct, it has the atmosphere of "hometown people". The characters of the two worlds are almost the same, but the people here prefer to write when they practice calligraphy, and they are used to grinding off the edges and corners, and the words are more rounded, while the italics practiced by modern people are more distinct in the corners such as horizontal folds and vertical hooks.

Of course, the handwriting varies from person to person, but it is impossible to judge anything based on the words described, Mu Yunyun just thought about it in detail by preconceived ideas.

Out of curiosity and possible future needs, she asked where the artillery was found: "Teacher, can you tell us where the cave where the artillery was found?" If I could, I would like to see the two words on the stone. ”

Teacher Xia can talk to them about this, and there shouldn't be any more scruples. But maybe the cave was used by her to study the ammunition formula, and outsiders were not allowed to enter, or the location was too far away to go, so Mu Yunyun asked this, instead of directly saying that she wanted to go.

"There's nothing you can't do, if you want to go, I'll take you there." It's still the direct Teacher Xia.

"The location of the cave is not unfamiliar to you."

At that time, the gate of the Jokhang Palace was breached by the army of Beishan, and the emperor asked the secret guard to flee with his only princess. Running all the way to Bianjing, the secret guard fled to the Big Buddha Temple with Ming Zhao.

In addition to the main peak where the Big Buddha Temple is located, there are more inaccessible mountains around the Lianshan Mountains in the southwest of Bianjing. When the people of Beishan forced into the Great Buddha Temple, Ming Zhao and the secret guards scattered, and they went around the forest and broke into the cave.

The location was hidden, and it took some effort for the guards to find her. Even if Ming Zhao goes again, he must identify it carefully so as not to get lost.

Therefore, Mu Yunyun wanted to come, and on the morning of the third day of junior high school, Teacher Xia brought her and Yu Chi Xinna here.

In the depths of Lotus Mountain, where the thickness of fallen leaves is piled up to one foot and you can reach your ankles, there is no way to walk along the stream to the source.

In front of it is a natural waterfall, the water flow is not urgent, the turquoise flowing water is like a huge canvas hanging in front of the mountain, and the waterfall of the most beautiful 5A-level scenic spot that Mu Yunyun has ever seen is nothing more than that.

Yu Chi Xinna looked back and forth, and then asked the face mask secret guard who was carrying Teacher Xia on her back easily, "What to do next?" ”

Teacher Xia got down from the back of the secret guard, "Ah Cheng take Yunyun in, it's too laborious to go back and forth, so I won't go, if Xinna wants to go, she can follow by herself, and she should practice her skills." ”

The secret guard named Ah Cheng looked at Mu Yunyun with disgust, and then picked her up, jumped over the waterhole below the waterfall in a few light jumps, and landed steadily on the stone facing the impact of the water.

Yu Chi Xinna felt cold when she looked at it, no wonder Teacher Xia reminded them to bring their robes.

Then the dark guard threw the iron hook with the rope upward, and the iron hook hung accurately somewhere above, and Mu Yunyun felt that he was swimming against the current. She is grateful that her weight in this life has not caused too much burden on others, but she is still so scared that she wants to scream.

When she felt that she was about to reach the top of the rope, Ah Cheng jumped with her, and the two of them plunged into the water curtain and disappeared from Yu Chi Xinna's sight.

The little girl couldn't help but swallow her saliva, "Teacher, I'm still not going......"

She was really curious about how Teacher Xia fell into the cave hidden in the middle of the steep waterfall.

As if seeing her question, an explanation came from her ear: "I was forced to jump from it, and I expected to use a knife to chisel into the mountain, but the place washed by the water was too slippery......"

The waterfall is not absolutely vertical, and there is a certain slope from top to bottom, and it is also possible to slide in from another road to a higher place.

However, the location of the cave is not high from the ground, and Mr. Xia later brought people to move the fort from below, so he made many different attempts here, and finally it was the craftsman who memorized the fort structure and went out to reorganize it after dismantling it. It's a pity that the ammunition was not dismantled and reorganized and studied.

The two of them outside continued to talk about the past, and Mu Yunyun had fallen into the cold cave. The curtain of water did not completely block the light, and it could be seen that it was an empty and pure hole.

The size seems to be just to put a gun emplacement.

On the stone on the cave wall, Mu Yunyun also saw the word "peace".

It's really upright in italics, the kind that can't be written by hand, and it's as upright as a printout.

She stared at the words and saw her origin, and Ah Cheng, who was guarding the entrance of the cave, continued to look at this girl with disgust.

Seeing that nothing could be done, I didn't understand what the lord brought her here to find.

Immediately, his eyes under the mask suddenly contracted.

When Mu Yunyun's fingers touched the word, a creepy third voice sounded in the cave.

"My descendants."

The majestic female voice came out, and the secret guard immediately protected Mu Yunyun behind him, holding the rope in his hand and ready to jump out at any time.

But no one showed up, only the voices continued.

"I buried the national protection cannon deeply, and I don't want future generations to be able to come here. Your chance, but not the blessing of the world. Those who get this cannon should keep their hearts and ensure that this cannon will not come out in troubled times.

The young people don't want to listen to my words, so they set up Gu in this word, and invite them into my dreams, and I will take you to see the stability of the present world...... Stable ......"

The sound echoed in the cave, forming a circle of echoes, and the unrealistic sound quality made Mu Yunyun seem to hear the sound coming from the loudspeaker.

Combined with the information conveyed in the words, she suspected that this was revealed by a certain senior with a voice recorder, and the switch of the voice recorder should be on the word harmony.

couldn't help but look at Ah Cheng, "Have you and Teacher Xia heard this voice before?" ”

Ah Cheng shook his head with his back to her, his eyes were still vigilant, "The lord said that these two words are sacred, and we haven't touched them." ”

Who would touch a word when they have nothing to do...... Mu Yunyun couldn't help but feel anxious for the person who called himself "I", the routine set up was too deep, and others didn't walk in, so he was embarrassed.

Oh no, she's gone.

The connection between the Gu King in his heart was suddenly cut off, Mu Yunyun's eyes were closed, and the temptation of the female voice could still be heard in his ears, "Come on, may the National Protector Cannon never come out again, and may the world always have peace......
