Before coming to the temple again, Du Wei could no longer feel the mystery here, and the area around the holy tower that had been baptized by war was slightly desolate.

"Let's go, let's go in." Du Wei urged Feng Si to go afar.

Because it was the first time for Feng Siyuan to come to a foreign land, what he saw and heard surprised him.

Especially when he saw the current Fan Wang, his jaw almost dropped.

"Green ...... Qing ...... "Although Du Wei had told him about Tsing Yi before leaving, when he saw Tsing Yi with his own eyes, he was still stunned, he couldn't believe that the man in front of him who was dressed in purple animal skin and had a full beard was the first guard by Feng Duhan's side before.

"What's the matter with this beard......" Feng Siyuan stammered.

Du Wei couldn't help laughing, and whispered to him when there was no one around: "Now Beifan has not all his heart in Tsing Yi, so at present, he must be powerful everywhere, the people here are fierce, and naturally make himself look as fierce as possible." ”

Feng Siyuan made a bitter face when he heard this, and muttered: "With such a look, I'm afraid that even Miss Li will be scared away, right?" ”

Du Wei quickly covered his mouth, and the two saw that Tsing Yi's face darkened in an instant, if they weren't familiar with each other, it would be really scary to look at Tsing Yi like this.

Everyone entered the temple, Tsing Yi arranged the guards of the North Fan outside the hall, and the people brought by Du Wei and Feng Siyuan stayed on the first floor of the hall.

After arranging everything, Du Wei took Feng Siyuan and the others to the secret door on the first floor of the temple.

Mr. Cui also accompanied him this time, thinking that he would see the legendary dragon vein with his own eyes next, and everyone had excitement on their faces.

Du Wei led everyone through the dark passage, came to the unusually strong secret door, and took out the two jade pieces.

Tsing Yi held a torch in her hand to illuminate her, and Du Wei inserted the jade pieces into the raised groove next to the door in turn.

Gala Gala ......

A muffled voice came from beneath the door.

Tsing Yi stretched out his hand and blocked Du Wei behind him, Feng Siyuan poked his head out curiously, but Du Wei pulled it back.

"Don't move!" Generally speaking, there will be mechanisms and other objects behind this kind of dark room or secret door, although she has never seen it, but she must not be on guard.

Tsing Yi drew his sword and pointed at the ground inside the door with the tip of his sword.

The ground reverberated with a crisp and solid sound, as if to prove that there were no traps or anything like that.

Du Wei and his entourage waited for half an hour at the door before boldly entering the door.

The space in the darkroom is not large, and it looks very ordinary, and everyone can't help but be a little disappointed.

What about glittering treasures? piles of diamonds and gold bars that look like hills...... The villain in Du Wei's heart is disillusioned.

On the walls of the darkroom, several maps hung on them.

Du Wei walked over and saw that all the signs on the map were marked in English, and she was even more sure that the "saints" that the Beifan clan believed in at the earliest were the same as her, and they had also crossed over.

Everyone else was roaming the room, each with a look of confusion and disappointment on their faces.

Du Wei carefully looked at the maps, and when she inadvertently translated the English marked on the map, she couldn't help but cry out "ah".

Everyone was startled by her and turned their heads to look.

"I see!" Du Wei shouted excitedly, she pulled the Tsing Yi and came to a map, "Do you recognize where this is?" She asked, pointing to the location marked on the map.

Tsing Yi had been marching with Wind and Twilight for many years and was very familiar with this kind of map.

"It should be the holy mountain here."

"Here's a map of minerals!" Du Wei said in a low voice.

Mr. Cui followed the trend and squeezed over, and Du Wei pointed to the next map, "This is a map of iron ore, that is the distribution map of oil......"

"What is oil?" Feng Siyuan was puzzled.

Du Wei was stunned, and didn't know how to explain, when she suddenly remembered the siege weapon developed by Mr. Cai, a staff officer under the wind and twilight cold tent, "Among the siege weapons made by Mr. Cai, the kind of thing that can be burned violently is this thing." ”

"It's fire oil." Mr. Cui said.

"Anyway, it's called differently, and this kind of thing is much more useful." Du Wei kept looking at several other maps and sighed: "No wonder it is said that those who have dragon veins can win the world, if they get this iron ore vein map, they can create countless weapons, if they have fierce fire oil, they can attack cities and plunder land, and the people can also use it for lighting......"

There were some things she didn't say, she vaguely remembered that in the ancient gunpowder recipe, someone used the asphalt produced by oil to control the burning rate of gunpowder, and this alone did not know how much bloody rain it would set off.

If this picture is born, it will definitely cause many forces to snatch it, no wonder the emperor did not publish this place to the world, but hid it and distributed it to his two favorite princesses.

On the contrary, if the crisis is on the side, this thing will surely turn the tide and be enough to save a country.

Feng Siyuan pulled Tsing Yi and looked around the map excitedly, pointing to the annotations on it from time to time, but unfortunately all the words on it were written in English, and they could only write down the annotations shown on it.

"This thing must not be passed on." Du Wei said, "It's better to find some confidants to depict this." ”

Tsing Yi nodded for a long time, and went out to arrange this matter first.

Mr. Cui has been concentrating on the house to find traces of the painted bone incense, although this legendary dragon vein is a little different from their imagination, but he obviously does not want to give up.

Du Wei also searched for a long time, but there was a mess in this secret room, and she couldn't know where to start.

"World ...... The princess ......" suddenly heard Mr. Cui's shout in a different tone.

She followed the prestige, but saw Mr. Cui holding a glass bottle in his hand, and a small pill lying quietly at the bottom of the empty bottle.

Du Wei blinked, she hadn't seen the painting bone incense, although she had taken it when she was a child, but she hadn't crossed over at that time.

"Is this really a bone painting?" She wondered, is there really such a thing in this world, she couldn't believe it.

Mr. Cui carefully opened the bottle, and a faint aroma of rouge instantly filled the room.

"It smells so good." Feng Siyuan couldn't help but admire.

Smelling the familiar scent, she seemed to see the god of luck beckoning to her.

Finally found it?

But this sudden surprise made her feel a little unreal.

As long as he takes it, he no longer has to worry that his weakened body will become as dull as the three-life stone at any time.

Thinking of this, she subconsciously raised her wrist, and the three-life stone tied to the red rope had almost completely turned into an ordinary stone.

It is said that this stone has become like this, and her body should be very weak, but this time she came to Beiban but it was not as difficult as last time.

Maybe it's really because of the bone fragrant fruit she took before that she has recuperated her body?

She was thinking when she heard the sound of footsteps outside the door of the secret room.

The three of them quickly glanced at each other, and at the same time a sense of unease arose in their hearts.

Mr. Cui hurriedly put away the medicine bottle in his hand, Du Wei walked in the front, and the three of them walked out together.

As soon as Du Wei walked to the door, she felt a cold wind blowing in her face.

"Sister, be careful!" Behind him, Feng Siyuan suddenly shouted, rushed over desperately, and pushed her out.

A sharp arrow with a black tail feather swept close to her side, and the cold light was striking Siyuan's chest......
