As for who is faster, the Golden Back Eater Ant Squad or the Snow Silkworm Squad, Ye Lin thinks that the Golden Back Eater Ants, who are both brute force, are better. After all, ants are born to be extremely good at teamwork, but snow silkworms are better because there are more insects, with only seven or eight thousand gold back Eater Ants, and only three or four thousand mining Golden Back Eater Ants.

Liu Qingqing beside her was stunned.

She is in a long position today.

The spirit insects can not only fight and kill enemies, but also act as coolie miners. The excavation speed is much faster than that of human cultivators. They are not afraid of hardship, fatigue, or dirt, full of energy and full of struggle...

"It's so terrible. I remember that every black steel stone that is long, wide and high is worth at least three hundred spirit stones. The mining speed is even more terrifying than picking up money... The income of the alchemy master is weak in front of the master."

In fact, the perception that other insect cultivators cannot mine is wrong. As far as Ye Lin knows, his master, Elder Sun, raised a kind of barbarian beetle specially used for mining. However, the mining efficiency is naturally far worse than Ye Lin's miner brigade, but it is still much faster than manual mining.

Moreover, manual mining requires high wages, unless the mine slaves do not have to pay, but the righteous way does not allow mine slaves to exist, so the cost of spiritual insect mining also has a great advantage.

Elder Sun's miner team is also compared with Ye Lin's miner team. The main difference is in the wisdom of the spirit insects and individual strength. Each spirit insect of Ye Lin's mind is no less intelligent than that of an adult, and all the spirit insects of the miner team are mutated spirit insects.

The mining efficiency is naturally very different.

However, no matter what, Elder Sun's idea of ​​controlling insects is very advanced, which gave Ye Lin a lot of inspiration.

Time flies quickly. As the mining team continues to dig downward, the ground becomes empty, and a bottomless pit is gradually forming, and a large amount of black steel stones are filled with the spiritual insects' panoramic bags.

But this is not a problem. Ye Lin only needs to have a thought, and the Qiankun bag filled with Xuangang stone enters the ancient ring space to automatically unload the goods, and then take it out and distribute it to the spirit insects to load the goods.

Dig down fifty feet deep...

One hundred feet deep...

Three hundred feet deep...

The temperature underground was rising, which made Ye Lin slightly worried.

"All ancient books have records that there are great terrors underground. Although this is a blessed cave, the underground structure should be similar to the world we live in. It would be that I would have dug it out if I was so lucky. It was hundreds of feet deep, so there should be no risk in this regard..."

Until he was digging to a depth of five hundred feet, the surrounding temperature was extremely high enough to melt ordinary granite, and Ye Lin was about to give up, one of the miners and spirit insects shouted.

"Master, I dug up the spirit stone, and the black steel stone seems to be gone!"

The other spirit insects also shouted excitedly.

"Master, I have also dug up a low-grade spirit stone!"

Ye Lin was delighted and flew over to check it out. Sure enough, the black steel stone became much rarer, replaced by low-grade spirit stones shining with light blue light.

"Okay, okay, it seems that the spirit stone ore vein has been found. For the lower-grade spirit stone, it should be the output of the small spirit stone ore vein. Everyone concentrates their efforts and digs out more valuable spirit stones first!"

"I understand the master!"

Spiritual stones are born one by one, about the size of a fist, which is much easier to dig than Xuangang Stone. The spirit insects dig very fast, and the spirit stones entered the spiritual insects' Qiankun bag like flowing water.

Ye Lin was overjoyed.

"I don't know that this spirit stone vein has existed for tens of thousands or hundreds of thousands of years. Even if the spirit stones are automatically converted into spiritual energy and dissipated, there will be at least several million!"

Ye Lin said: "Everyone remember to count the number a little."

"clear!"

Finally found the spirit stone vein, Ye Lin was overjoyed.

But he did not lose his vigilance.

"Xiaobai, you feel it all open. Once you find any abnormal movements underground, I will immediately take away all the spirit insects and leave here at full speed."

Xiaobai nodded.

The speed of digging spirit stones was extremely fast, and more than two million pieces were dug in one hour...

Three hours later, the spirit stone veins seem to be about to be emptied.

Xiaoqi suddenly shouted: "Master, the quality of the surrounding spirit stones has increased. Occasionally, medium-grade spirit stones can be found, and two top-grade spirit stones have even been found..."

Ye Lin was slightly happy.

"According to the ancient books, this may be close to the area where the ore mother is located. Be cautious. Although the ore mother of the spirit stone is recognized as not aggressive, it is best not to anger such a strange thing that seizes the creation of heaven and earth..."

Ye Lin just finished speaking.

I heard a muffled "bang" sound suddenly coming from the ground...

Then I heard "bang bang"... "bang bang"... like a heartbeat, the sound seemed to be increasing according to a certain rule.

Ye Lin's face was serious.

"Everyone should withdraw quickly. It seems that the Spirit Stone Mine Mother has woken up!"

All the spirit insects retreated back to Ye Lin like a tide.

"There shouldn't be many spirit stones left. Let's leave here directly to avoid any trouble!"

Ye Lin dug a huge amount of black steel stones and six or seven million spirit stones here, and has made a fortune. There may be hundreds of thousands of spirit stones left. In order to avoid risks, Ye Lin would not want it.

Ye Lin waved his hand, and the army of spirit insects turned into spiritual lights and disappeared without a trace.

Ye Lin couldn't help but his heart beat faster at this moment. He turned over and pulled Liu Qingqing to sit on Xiaobai's snake body. Xiaobai's figure flashed and turned into a long rainbow and flew towards the exit of the mine...

As a result, Ye Lin was left strangely in place!

Ye Lin, who seemed to be wrapped in something as soft as cotton, had his face changed drastically.

From beginning to end, he didn't feel anything around him, but he was so weird that he couldn't move at all...

"Master...why are you..."

Xiaobai, who had just flew out, found that Ye Lin could not move, and instantly turned around and exclaimed in surprise.

Liu Qingqing's face changed drastically at this moment.

"It is very likely that the mine mother left the master. The ancient books record that the mine mother is invisible and cannot be seen. Even the strong man in the out-of-body stage cannot capture it!"

"Usually, when the mine mother is awakened, she will change places and continue to sleep. She will not attack people, so how can she leave her master..."

At this moment, Ye Lin suddenly felt a tingling pain coming from his throat, and he saw two blood holes appearing in the artery in his throat, as if he was bitten by a monster. He felt a large amount of blood gushing out...

But the blood did not splatter everywhere, but floated in the air like smoke.

Seeing this, Xiaobai was furious and opened his mouth suddenly, and a thunderous sword energy induced it.

But the thunder sword energy flew around Ye Lin several times, but he didn't touch anything, and even Ye Lin's blood was not contaminated at all.

This is really weird.

Ye Lin endured the pain and blood rushing: "Xiaobai, don't be excited, we can't touch this thing, I seem to feel it gradually. It is now... very excited, just like you who have sucked blood!"

"The real identity of the mine mother is very likely to be an invisible insect!"
