After Chen Dali finished sowing all 300 plots of land in the farm, he became idle again. He wanted to open up land without any extra plots, and had auxiliary spiritual instruments to help him water. Chen Dali basically didn't need to spend any effort to take care of it.

Chen Dali, who had nothing to do, walked into the Yunling Mine Cave again.

Of course, it is impossible to explore the ore layer above 60 layers. Chen Dali still remembers the scene of being bullied by cave flies before.

However, building a void fishing platform requires 5,000 stones, and purchasing auxiliary spirit instruments also requires black copper ore. Chen Dali looked at his inventory and currently he only has 2,530 stones and 237 black copper ore.

There was so little material that Chen Dali had to brush the materials back and forth in the 60th layer of the Yunling Mine Cave. Five thousand stones were said to be more than more, and less than less. It just took more time.

Day 190.

Chen Dali watered the outermost plot of spiritual liquid and took Sister Ya into the Yunling Mine Cave.

"What other materials are you going to dig today?"

After a rough look at the storage box, Chen Dali found that there were more than 3,000 stones, and the reserves of black copper ore also reached 527.

Chen Dali felt that the efficiency of collecting materials in the past three days was pretty good. He only mined the ore layer with the Lingfu meter, and did not need to climb the ore ladder at all, saving a lot of time.

The reason why Chen Dali can mine ores in this way is entirely due to the refresh mechanism of the Yunling Mine Cave.

The ore layer in the Yunling Mine Cave is not static. Chen Dali found that he reached a ore layer through the Lingfu meter. After leaving, he would return after a certain period of time. The ore layer would be refreshed again. The stones inside would change whether they were mined or not mined.

It was based on the rules he had figured out that Chen Dali could mine more than 200 black copper ore to more than 500 in such a short time.

"The amount of black copper ore seems to be almost the same. Starting today, I will do my best to mine the stones and save up 5,000 yuan as soon as possible."

...

Under Sister Ya's perception, a morning passed.

"Uh..." Chen Dali stretched, "It took more than 100 pieces of stone in one morning, and the speed was OK."

In fact, there is a probability that stones can be produced by knocking stones. Except for gray-white stones that stably produce stones, the probability of other stones being produced by knocking stones is only one-third.

Today, Chen Dali's character seems to be pretty good, and the probability of knocking out stones is about one-half, otherwise he wouldn't have been able to knock more than 100 pieces in one morning.

After a while, Chen Dali continued to ride the Lingfu meter to mine the stone back and forth.

...

In the afternoon, Chen Dali had mined more than 200 pieces of stone, basically the usual amount of mining in one day.

Chen Dali took the Lingfu meter to move to another mine to continue mining, but suddenly Chen Dali found that he had arrived at the 60th floor.

"What's going on? Could it be that I was too tired to dig stones and accidentally chose the sixtieth floor when I was sitting in the Lingfu Arts?"

Although he came to the sixtieth floor again in a daze, Chen Dali didn't care too much. After all, there was no knocking on the stones on which layer, and the ore layers without monsters were all good ore layers.

After some effort, he knocked all the stones in the sixty layers. When he was about to enter the Lingfu meter and return to the mine layer below, Chen Dali glanced at the mine ladder and an idea arose.

"Do you want to go to the mine above to see?"

Chen Dali was also instantly shocked: How could I have such a dangerous and desperate idea? It was said that it would develop in a despicable way, and it would be safe and stable.

Just as Chen Dali tried his best to control himself, approached Lingfuyi step by step, and was about to enter it, Chen Dali stopped.

"Would you like to go to the mine above to see it? Just go and take a look. If there is any danger, just slip away."

For a moment, Chen Dali felt like a kitten was tickling him, and a strong curiosity encouraged Chen Dali to walk towards the mine ladder.

"Madan, let's take a look again. If there is danger, just slip away quickly. It shouldn't be a big problem."

Chen Dali, who was standing in front of the Lingfu Circle, turned around, walked to the mine stairs, and started climbing straight up.

"What am I doing? The mine layer upwards of sixty layers is so dangerous, why can't I help but want to explore?"

In the mine ladder, Chen Dali kept reflecting on his actions, but since he had already taken action, he was not ready to give up halfway.

Soon, the entrance to the sixty-first floor appeared above the head.

When Chen Dali walked into the mine on the 61st floor, he was very glad that there were no annoying cave flies inside.

On the contrary, a silver-white stone attracted Chen Dali's gaze. Looking at the silver-white slightly more delicate stone that was completely different from the surrounding stones, he estimated that this might be the mitril silver ore needed for the secondary upgrade tool.

He used a pickaxe to hit the silver-white stone twenty times, and the ore broke open and a piece of silver-white ore fell out.

"Drip, get Misilan Ore×1"

"I was right, it seems that the silver-white stone is Mithril ore. The previous ore layer restrictions in the system should be to prevent me from obtaining Mithril ore in advance."

Seeing the silver-white, nearly circular mitrilite mine in his hand disappear, Chen Dali began to look for traces of other mitrilite ores in the mine cave.

Unfortunately, after searching in a circle, only one mitril ore seemed to be refreshed in the sixty-one mine caves, and the rest were just ordinary stones.

"It seems that there will be a mitsilver mine if you continue to move up. If you mine a few more mits of mitsilver mines, you will get a lot of harvest today."

Chen Dali, who was blinded by the mitril ore, subconsciously ignored the danger in the mine cave and walked along the mine ladder to the sixty-second floor.

"This is...the monster layer?!"

When Chen Dali saw the green entrance on the sixty-second floor, his face turned blue and he touched the monster layer.

Thinking about the scene of a bunch of cave flies besieging him, Chen Dali shivered and quickly climbed down the mine ladder, trying to leave.

"Drip, the monster invasion layer has not been resolved, and I cannot leave it."

Even though he had not entered the mine at the 62nd floor, the system still determined that Chen Dali needed to solve the monsters in the mine before he could leave this floor.

Hearing the system's prompt, Chen Dali, with a regretful face, looked at the green mine above his head and cried loudly: "Why do I have to climb up? I'm still too greedy. I originally stabilized my development and returned to continue digging stones and did nothing. Now it's too difficult to ask me to clean up the monster layer!"

Forced to the point of being helpless, Chen Dali had to enter the 62nd floor mine cave.

Standing at the entrance, looking at the earth walls around him that were no different from the previous monster invasion layer, Chen Dali felt a little desperate because he knew that the monsters in this monster invasion layer would definitely be cave flies.

It took a lot of effort to solve a cave fly by himself before. When Chen Dali thought that there would be a bunch of cave fly waiting for him in the mine, he turned blank: "It should be killed instantly!"

Chen Dali’s luck today is not known whether it is good or bad. He collected materials and shuttled back and forth in the mine cave without encountering monster invasion layers. Now he just climbed up the mine ladder and won the first prize.

Chen Dali, who was standing at the entrance of the mine, stared blankly in front of him. He was unable to move forward and retreat for a moment, but he didn't know what to do.
