That night, Meng Zhang sneaked to the location of the red copper mine. He took out the insect jar, injected genuine Qi and gently driven it.

After a while, there were waves of vibration on the ground. A moment later, large holes appeared in the ground ahead.

The number has increased to nine sand worms, which have drilled out of the ground.

The originally rebellious sand insects are now as clever as children and automatically line up in front of Meng Zhang.

Meng Zhang showed his deceptive eye and carefully examined the stomach of the sand bug in front of him.

The huge sand bug, its huge abdomen has become bulging. Obviously, it is full of red copper ore.

After many attempts, Meng Zhang found that every ten days or so, the abdomen of the sand worm would be almost full.

The Sandworm domesticated and controlled by the insect control tank overcomes its own nature and reduces the sleeping time.

Once released by Meng Zhang, he will take the initiative to drill into the ground and will not run around. Instead, he will directly enter the red copper vein and begin to devour the red copper ore.

Every time they devour the ore for a period of time, the Sandworm will stop and rest for a while. When you recover, you will continue to devour the ore.

In this way, these hard-working miners continued their work until they filled their bellies.

He took all the sand insects back into the imperial insect jar. Taking advantage of the night, Meng Zhang secretly returned to Taiyi gate.

As soon as he returned to taiyimen, Meng Zhang released all the sand insects and controlled them to forcibly spit out all the swallowed minerals.

Naturally, the disciples of the sect are responsible for cleaning up the red copper ore vomited by sand insects.

Take out the specially purchased food for feeding demon insects. After feeding all the sand insects, Meng Zhang put them all into the imperial insect jar.

Sand insects need to rest in the insect control tank for a few days to recover their consumed physical strength and energy.

The red copper ore cleaned by the disciples will be sent to the refining room.

The so-called refining room is just a separate hall that has just been built. There is a first-class inferior refining furnace and many spiritual wood as fuel.

Tian Li spends most of his time in the refining room.

Tian Li is now a qualified apprentice of a tool smelter.

He seized all his spare time to refine red copper ore as much as possible.

In fact, even if Meng Zhang also takes a lot of time to refine red copper ore, the refining speed is far behind the speed of sand insect mining.

Looking at the more red copper ore piled up in the storage room, but there is no time to refine it, which is really a happy worry.

Meng Zhang is not in a hurry. It is not a bad thing to refine slowly and sell in a long stream.

Direct disposal of hematite ore will not only lose a lot of profits, but also easily expose the existence of hematite.

The thick earth God was right. This red copper vein also contains many associated minerals.

The associated ore is phlogistic crystal and Xuanjin, which are much more precious than red copper.

These associated ores are carefully separated and refined separately.

The revenue of this red copper mine has become the most stable financial source of taiyimen.

Meng Zhang was considering whether to train more apprentices among the disciples of the sect.

Anyway, the cost of cultivating the apprentice of the tool refiner is not high. These disciples have poor spiritual root qualifications. It is also a good thing for them to learn more skills.

With more apprentices, the speed of refining hematite can also be greatly accelerated.

However, this matter is not urgent. Let's put it aside for the time being.

At present, there are only about ten disciples in the sect, and not many of them practice fire attribute skill.

At this time, it has been almost two months since the God of thick earth fell into a deep sleep.

After the earthquake, monks from all over the country turned the area upside down. Even the bottomless pit was thoroughly explored.

All the monks did not find any valuable clues in the local area. The legendary monk's cave disappeared at all.

Even Meng Zhang was a little strange when he heard the news.

I clearly found the monk's cave and the protective Dharma array outside the cave, not counting the monks trapped in the array.

How come all these disappeared without a trace, and there was no clue left?

However, he was curious again. Meng Zhang firmly remembered the command of the thick earth God general and resolutely did not enter the area again. The farther away he was, the better.

The heat of the cultivation world always comes and goes quickly.

The practitioners who didn't find any clues in that area soon lost their patience and scattered in a crowd.

There are many places worth exploring in the cultivation world. There is no need to waste time in a worthless place.

This matter passed without any follow-up. Meng Zhang was also greatly relieved and charged Li Xuan to bury the secret that he and others had entered there deeply in his heart and never let it out.

Since this incident, Meng Zhang has also learned from the previous thick earth God general and patrolled around Taiyi gate from time to time.

If you find any problems, you can deal with them in time.

Taking advantage of the opportunity for the sand insects to rest in the imperial insect jar, Meng Zhang decided to go a little farther.

Meng Zhang rode a wind chasing pony and ran all the way to the abandoned Mengjia oasis.

In the chaos of sand monsters more than ten years ago, Mengjia oasis was broken by sand monsters.

Like all oases destroyed by sand monsters, the spiritual veins in Mengjia oasis were destroyed, and the oasis completely degenerated into desert in a very short time.

The once prosperous Mengjia oasis has completely turned into ruins.

Meng Zhang made a turn next to Mengjia oasis.

Tens of miles to the north is the area where the earthquake occurred, and it is also the place where Meng Zhang fled.

Meng Zhang did not dare to take the initiative to enter there, but changed direction and continued to ride the wind chasing foal.

Meng Zhang headed south. Before he ran out fifty miles, he slowed down his pace.

Not far ahead is a series of hills.

Meng Zhang rushed up the highest hillside on a wind chasing pony and looked down.

Several hillsides form a circle, and in the middle is a valley of more than 100 mu.

Meng Zhang felt it carefully on the hillside. Yes, there was a strong aura here.

He cast a false eye and looked around carefully.

Then, he performed the earth hiding technique and dived directly into the ground.

After a long time, Meng Zhang came out of the ground.

Meng Zhang made no mistake. I don't know when a brand-new spirit pulse appeared here.

Meng Zhang had passed here before. It was clear that it was a desolate mountain. There was no spiritual pulse at all.

Meng Zhang also mastered the fur of the art of geomancy and surveyed around.

After a careful survey, Meng Zhang had a little guess in his heart.
