Hanjiang focused his attention on the three non-miner surface people. If you are a miner www.biquge.info their lives will not leave this mine, which is a record of the entry and exit of people on the surface. Even if the people on the surface have mastered some unknown magical technology, it should only be limited to transmitting information and matter...... Han Jiang didn't think they could overcome the miniaturization of the teleportation magic array. If you want to bring the crystals in without being discovered, you can only bring them in slowly in batches.

However, there is a problem with this. When they enter the mine with those crystals, won't they attract demonic beasts to attack them?

Maybe they have a facility that can block out magic. That kind of crystallization should release some kind of magical aura to attract demonic beasts, and it only needs to use some kind of container to cut off the breath. If the surface people hadn't even mastered this technology, it would be estimated that their facilities for producing crystals would have already been dismantled by the demonic beasts.

In other words, the container used to cut off the breath should not be a small thing, how did they bring it in......

Forget it, don't think about how they brought it in, let's confirm who it might be.

Han Jiang looked at the first document. This surface man is responsible for resource procurement at the mine. The consumption of daily necessities in the mine is huge, and if the miners are not allowed to eat and drink well, it will seriously affect the efficiency. All kinds of daily necessities of the mine are purchased by the purchaser in the sunset city, which is not a small expense; the surface man who is quite shrewd in business is quite good at this kind of work, and every time he goes out to purchase materials, he can save a lot of money for the mine, and in the mind of the mine director, this surface man is quite shrewd and capable.

The second information belongs to one of the drivers here. Transporting ore out of the mine requires the use of heavy goods vehicles, which are not easy to drive. The surface man had experience driving heavy trucks and was a veteran, and it was easy to get a position once he came here. He often had to return to the mines and the city of the setting sun, and he had to transport the refined ore there, and he was very busy every day.

The third information is that of a researcher. There is healthy competition between each mine, and they will regularly send observers to other mines to observe and learn from the experience, and then improve their own mines. The surface man has a solid knowledge base of mechanics, so he came here to apply for a mechanical researcher. He often travels from one mine to another, observing and learning about their mining methods and the distribution of labor, and when he returns to the mine, he submits his observation report. His report pointed out many areas for improvement in the mine, which contributed to the development of the mine.

Only these three surfacers were allowed to enter and leave the mine on a regular basis, and if the surfacemen really planned to attack here, one of the three must have been inserted by the surfacer organization.

Wait, the words of the people who are inserted by the surface people...... Speaking of which, it shouldn't have been long since they researched and crystallized, right?

So to speak...... It shouldn't take long for them to send people to the mines?

"Excuse me, are any of these three people who have only recently come here to work?" asked Han Jiang.

Maybe...... Will the problem be solved fairly easily?
