Jun Qianqian glared at Luo Ze, if she missed the clue because of this, she would ignore him!

"I know it's wrong!"

As an excellent patriarch, you must have the advantage of being able to bend and stretch, and Luo Ze immediately admitted his mistake.

Then he raised his head to look at Jun Qianqian with pitiful eyes.

"You don't come to this set!"

Jun Qianqian turned her head away from looking at his face that made her easily shaken, and the clansmen looked at his huge contrast, and suddenly felt that the patriarch's deterrent power was gone.

Jun Qianqian pouted and looked at the blue pebble in her hand, originally just wanted to divert her attention, but it was really too successful, and she completely ignored Luo Ze, who was still bending over to sell cuteness.

The pebbles were uniformly sized and had a crystal clear blue color, and she rubbed them hard with her fingers, feeling that the hardness was not very high.

"What did you find?"

Seeing that her expression became serious, Luo Ze stopped making trouble, and hurriedly asked Jun Qianqian about her discovery.

"This one seems to be copper sulfate."

Jun Qianqian took the bamboo tube, scooped up the compass with convulsions, threw it aside, and threw all the pebbles into it.

Sure enough, after she shook it slightly, the blue pebbles were gone, and when the water in the bamboo tube was poured out, it was also dyed a faint blue.

"What's the use of this thing?"

Everyone also saw that they had found something good, and hurriedly surrounded them.

"It's called gall alum, and it's a treasure, which can not only be used for sterilization in agriculture, but also to make dyes."

The main ingredient of gallium is copper sulfate hydrate, which she is familiar with in high school chemistry.

Recalling Xia Lan's colorful clothes, with copper sulfate as a fixing agent, they can also dye cotton cloth in a variety of beautiful colors.

What's more, where gallium can be found in nature, there must be copper mines nearby.

Make a fortune!

The use of copper sulphate was explained to the tribesmen, and the tribesmen's eyes were as bright as wolves, and they immediately rushed to the place where they found the gall alum, and dug up all the small blue stones and put them in baskets.

"Copper has many uses, and electricity, light industry, and weapons manufacturing are all inseparable from this kind of thing!"

The people know the preciousness of metal, and they are very eager to find it.

In metals, the chemical properties of copper are relatively stable, pure copper can be found in nature, and the green color of azurite is also extremely easy to identify.

"I didn't expect the iron ore to be found, so I found the copper ore first!"

Jun Qianqian was very happy, this mountain near the Baiyan tribe is really a treasure.

"Is copper more important than iron?"

Luo Ze walked next to Jun Qianqian, and his most important task was to keep her safe.

"It depends on the situation, at this stage, the use of iron ore is definitely greater, but copper will come in more places in the future, and copper will not be used to make artillery."

Copper is soft and is used to make shells, which minimizes wear and tear on the barrel.

The two walked in the middle of the procession, the people scattered, but not too far away, and they searched along the foothills, bound to turn the mountain upside down.

"The discovery of copper deposits nearby can be regarded as confirming the existence of ore veins, and the geological changes here must have been frequent in the past, and I really want to dig up the whole mountain back."

Jun Qianqian said to Luo Ze while walking, looking elated, but the mountain road was difficult to walk, and she couldn't jump.

"Sooner or later, this place will be ours."

They had climbed to the top of the mountain, and Luo Ze looked into the distance, which was already far away from the Baiyan tribe, and there was no meadow to be seen in the wilderness tribe, for the tribe in the southeast, it was a land that no one had set foot on.

"If we find the ore, we will refine the metal first, and then send it back to the Purple Flower Tribe by car, and wait for the winter to concentrate on forging."

The two walked side by side, and suddenly Jun Qianqian felt a softness under her feet, thinking that she had stepped on something, so she hurriedly looked down.

"Be careful!"

Luo Ze saw that her figure was sinking, and thought that there was an illusion.

But his body didn't need to react to act, he grabbed her arm, but he didn't expect that the weight of the two of them together accelerated the collapse of the ground!

"Ah——!h

Jun Qianqian's scream penetrated the dense forest in the mountains, and the clansmen immediately rushed back to check when they heard the sound, but they didn't see the shadows of the two, only a bottomless hole remained in the ground.

Is this what it feels like for a wild boar to fall into a trap? She also experienced it herself.

Jun Qianqian was held in Luo Ze's arms, and both of them were thrown into pieces, she took a sharp breath and groped to confirm whether the two were injured.

"Qianqian? You okay? ”

Roze's voice came from above her head.

"I'm fine, you're going to be a human cushion for me!"

In the darkness, only a glimmer of light came through the hole above her head, Jun Qianqian patted Luo Ze's arm that was holding tightly, she was tightly protected, and there was nothing wrong with her.

"That's good."

Luo Ze breathed a sigh of relief.

"What about you?"

As soon as Jun Qianqian asked, she heard a call from the entrance of the cave.

"Patriarch! Qianqian! How are you guys? ”

It was Ana's shout.

"We're fine! Everyone else should stay away from the hole! Find a solid ground and don't move! ”

Jun Qianqian hurriedly reminded the people on the ground, but her voice was too quiet, so Luo Ze shouted for her again.

"What do we do now?"

Suddenly, the two main backbones fell into the pit, and the people were a little dazed.

"Find a safe place to stand and take the rope out."

Ana asked everyone to listen to the patriarch first, this pit is very deep, I don't know if their rope is long enough.

"Roze! I throw the rope to you! ”

Ana dropped a stone at the end of the rope from the hole, the length of the rope was a little insufficient, but the pit was not straight up and down, and it was possible to climb up the slope for a while.

"Why is there a pit here?"

Jun Qianqian asked Cang Tian speechlessly, she looked up at the rope with a solemn expression.

The soil at the entrance to the cave is so fragile that it could collapse again at any time.

"We need to climb up as soon as possible."

Luo Ze pulled Jun Qianqian, who was sitting on the ground, up, both of them were disgraced, she grabbed the rope and began to climb up hard, Luo Ze dragged her behind her.

Suddenly, Jun Qianqian's advance stopped, she didn't move, and Luo Ze followed behind her and held her breath.

"We can't seem to get out."

Jun Qianqian looked at the other end of the rope, the crumbling soil layer had begun to collapse again!

"Let go!"

She only had time to utter one last shout when the darkness in front of her overwhelmed her.
