But even so, it still made Tang Ye feel an unprecedented horror.

If this technique is allowed to develop for a few tens or hundreds of years, won't it already have the modern scientific and technological level of his original world?

Thinking of this, Tang Ye gradually calmed down.

Even if the trick can really develop to that extent in the future, it will be in the future. At least for now, these tricks weren't enough to really stand up to his progress.

There are also soldiers in the vicinity of the machine, but it is a range-of-area control. However, Tang Ye still found an opportunity and secretly took away a machine man.

However, the soldiers who controlled it did not notice anything unusual, so it seems that the soldiers could not control every single one of them.

But presumably after the work is over, it will definitely be counted, but at that time it will be too late to find that there is one less.

The job of these people is to mine ore, but their efficiency is undoubtedly much higher than that of the group of humans down the mountain.

In addition, Tang Ye noticed that the entrance to the mine cave in front of them was actually twenty or thirty meters high and more than ten meters wide, as if something huge was allowed to enter and exit.

Looking at these mechanism giants, and then looking at the huge entrances and exits, Tang Ye suddenly realized that this might be the hiding place of the mechanism giants.

Without hesitation, the four began to enter the hole.

Unlike the human caverns below, the caverns here do not have a downward trend, but instead begin to slope upwards. And the depth is far from being comparable to the mine below.

Tang Ye and Yang Ke, plus the little girl on his back, the four of them walked for more than half an hour. During this period, Meng Xiaoye was already asleep on Tang Ye's back.

Soon, the remaining Tang Ye and the three finally reached the end of the passage, but they were blocked by a huge gate.

Along the way, they saw hundreds of machine men in the cave. But these traps only work in the passage, so the giant door is still closed.

Looking at the huge metal door that was more than twenty meters high and more than ten meters wide, Tang Ye, Yang Ke and Guan Li all had a deep sense of powerlessness.

"If you want to open a door like this, you need a mechanism, right? I don't know where the switch is. Tang Ye looked around, looking for traces of the switch.

Guan Li and Yang Ke also shrunk into the invisibility cloak, probing around.

At this time, Tang Ye suddenly noticed that on the far right side of the metal giant door, there was a strange depression. It's like something that needs to be inlaid with.

Looking at the somewhat familiar depression, suddenly, Tang Ye thought of the metal token he had found in the City Lord's Mansion before!

He quickly removed it from the system, and found that sure enough, the shape of the metal token was exactly the same as the groove on the door.

Tang Ye looked back at the small number of agents and soldiers, and after hesitating for a moment, he finally put the token into the groove!

However, to the trio's surprise, nothing happened. The giant gate also showed no signs of trembling.

"What's going on?" Tang Ye looked at Guan Li with a confused expression. After Guan Li took a step forward and groped for a while, he noticed that after the token was installed, he had to press it hard.

For a moment, the entire mine suddenly began to tremble, and at the same time, the frightened eyes of the surrounding soldiers looked at the metal giant gate in front of Tang Ye!
