Zhao Xixi said: "Although there is very little visible life in this underground world of tens of kilometers, there is some after all. The passage must not be closed. This is not only the passage connecting the cave to the sky, but also our way back."
Seeing that what Zhao Xixi said was reasonable, Song Yijin stopped insisting. But the poisonous vapor could flow back at any time, and he needed to lead them out of here as soon as possible.
The sound of the dragon's roar is clear and shocking.
Song Yijin frowned and looked ahead, and said two words with firm eyes, let's go!
Their steps were extremely fast, with the golden ridge appearing and disappearing under their feet, until Song Yijin, who was walking in the front, accidentally slipped and fell forward heavily.
The three of them, Zhao Xixi and others behind them, were all caught off guard. They stepped on piles of beads under their feet, and they all fell to pieces.
Chen Mingzhi fell the hardest because his back was still injured and he moved a little slower.
He fell down with his mouth open, shouting "Ouch, ouch". At first, everyone complained about the pain when they got up, but when they saw what Chen Mingzhi said, they all thought it was funny and laughed non-stop, so they no longer knew the pain.
Chen Mingzhi wondered why they kept laughing, and he was not the only one who broke it.
He wiped his mouth with his hand and realized that his mouth was full of shit. He knows this, this is silkworm shit. Their family used to raise silkworms and called the silkworm excrement silkworm excrement.
Only then did everyone realize that the small piles at their feet were all made of this kind of silkworm excrement, which had dried.
"It's strange that there are mulberry silkworms here!" Jiang Xiaobao is also familiar with this kind of silkworm excrement. His grandmother often uses silkworm excrement as pillow filling. It is comfortable and cool, and has a faint fragrance of mulberry leaves. It is beneficial to sleep.
Zhao Xixi grabbed a handful of silkworm excrement, put it up her nose and inhaled twice, "It has a sour smell, not mulberry leaves."
"Then it's not silkworm excrement, maybe it's something else. I remember the poop of bean bugs is similar to this." Song Yijin also grabbed a handful and smelled it, then crushed it with his fingers and found that there were golden particles inside. His eyes flashed, and he opened them a little more to take a look.
"There is gold in this silkworm sand! The content is quite high!" Song Yijin couldn't hide his joy.
When Chen Mingzhi heard that there was gold, his eyes lit up. There was silkworm sand under their feet, and there was more and more silkworms under their feet, with no end in sight. He swallowed his saliva: "If the silkworm sand here contains gold, then the weight of the gold extracted is also considerable."
Jiang Xiaobao agreed with his view, "And the refining process is also simple. You only need to remove the silkworm excrement." After the sand is dissolved in water, it can be extracted."
Unexpectedly, Song Yijin urged them not to stay and leave quickly. His eyes were originally filled with joy, but now they were frowning. Chen Mingzhi was puzzled and asked: "Cousin, do you want to leave in a panic?"

"Poisonous vapor!" Song Yijin did not allow them to doubt and stood up first and walked forward.
Chen Mingzhi woke up from the dream of making money on Canfa and hurried to follow. The thickness of the silkworm sand under my feet is getting thicker and thicker, and it makes a rustling sound when I step on it. Fortunately, my feet will not sink in when they land on it.
After walking for half an hour, the Golden Ridge appeared again. Although it was covered with thick silkworm sand, the golden light could not be covered up. But Song Yijin stopped and used his feet to pull at the silkworm sand. The golden ridge here was obviously abnormal. It was concave, unlike the ones at the back that were all convex.
"Golden-eating silkworms!" Song Yijin said.
"What are the golden silkworms?" Chen Mingzhi asked warily.
/p>
"The gold contained in these silkworm sands is the excrement after eating gold. In addition to gold, they also eat rocks."
Chen Mingzhi shuddered, he seemed He was scared of insects, and the wound on his back that was parasitized by sea onions has not healed yet. Fortunately, the wound was not inflamed. Jiang Xiaobao even felt that sea onions had great medical research value. Because it not only has the ability to regenerate beyond earthworms and sea cucumbers, but can also penetrate into the host's body without causing inflammation and live in symbiosis with the host for a long time. If this magical creature can be brought to the ground, it will definitely shock the scientific community.
Before they had time to think about it, Song Yijin urged them to leave quickly.
In a hurry, Jiang Xiaobao grabbed two handfuls of silkworm excrement and put them into his backpack. Because the rock salt he collected before came in handy at a critical moment, and these silkworm excrements might also be useful, and they could be sent to scientific research institutions when they get out.
The four people marched for an unknown amount of time, and the silkworm sand under their feet became soft. Water began to flow downward on both sides of the valley wall, and the air was moist.
"Look, what is that?"
Jiang Xiaobao, who was walking at the back of the team, found brown silkworms on the ground, all densely packed on the golden ridge.
It turned out that they were not stepping on silkworm sand, but directly on silkworms. No wonder their feet were soft.
But the strange thing is that the silkworm will not explode after being stepped on. After being stepped on, the mouthparts will evert out, but it will quickly retract and the body will return to its original shape.
"These are gold-eating silkworms!" Zhao Xixi said, "Except for their color, they are one shell larger than mulberry silkworms. The patterns on their bodies are very special, like some mysterious symbols."
Song Yijin used his feet to peel away the thick layer of silkworm sand on the golden spine, revealing the golden silkworms inside. All of them were round and eating the golden spine crazily. Some of the full ones crawled outside, and those outside went in again. Climbing inside the golden spine and taking turns eating, they are well trained.
