Chapter 641 (1/2)

As he continued to drill down, Peng Ming's mood became more and more anxious and irritable. After all, this speed is too slow. If it continues like this, he will be far from completing the drilling task within the scheduled time. However, he knows that there is no way. He needs to know the drill bits of the drilling equipment they use, It has been made of more advanced materials of human civilization, and its material hardness has reached 230.

Such hardness is much higher than that of diamonds. After all, the hardness of diamonds is only 100, that is, twice that of diamonds. However, even so, the drilling speed is still so slow. It can be imagined how strong the hardness of their underground ice layer is at this time.

Moreover, as they drill for a long time, the deeper they drill, the longer the time required for the same depth. It can be imagined that the hardness of the underground ice layer is gradually strengthening.

Finally, when Peng Ming's drilling equipment drilled about 700 meters underground, the drill bit was finally scrapped. Even with a new drill bit, the daily speed has accounted for less than 50 meters.

At this time, it has been three days since they landed on Mars, which makes everyone very angry.

At the same time, even the spacecraft and the earth command center are very dissatisfied with such a slow progress.

It belongs to the earth command center. Immediately let the spacecraft airdrop higher strength drill bits to speed up the drilling of ice.

Of course, Peng Ming and his team are not only exploring the ice layer above the underground lake of Mars, but also drilling less than 2km away from him.

However, compared with Peng Ming, the drilling progress there is slower. It has only been drilled down until now. It is only less than 400 meters. This progress is not satisfactory.

However, fortunately, with the replacement of the drilling bit made of new materials, the speed is much faster. After all, the materials used by the new drilling bit are made of the materials with the highest hardness in civilization, and their hardness has reached 285.

But it just went down again. At a depth of less than 200 meters, its speed slowed down again, which made everyone helpless and angry.

”Report captain, the drill bit is stuck.” that day, when Peng Lin and others reluctantly continued the drilling work, the professional in charge of drilling in their car reported to Peng Minghui.

”What is stuck? How is this possible?” Peng Ming looked at the professional with a shocked face after hearing the report from the professional staff responsible for drilling nearby.

”Captain! The drill bit is really stuck, as if it was stuck by something with super hardness,” the professional continued.

At this time, Peng Ming was even more shocked. We should know that the drill bits they use now are made of the hardest materials of human civilization. The cost of such a drill bit is as high as tens of millions of yuan, which is why they have not been willing to use it before. Moreover, in such a state, even there are only two sets on their spacecraft.

But now the drill bit made of this material is stuck, so he can judge that it is definitely not as simple as he thought under the ice, because the ice formed by ordinary water can not reach such hardness even if the hardness is higher and the temperature is lower.

According to the current situation, they are likely to drill into superhard material that the earth does not have, otherwise, the drill bit can not be stuck.

So he immediately ordered to stop the drill and prepare to pull out the drill to see the situation.
