Lin Congfeng rubbed his numb wrist and frowned.

"Feng'er, I have a great idea."

"Jiu'er, you can spare me."

"Really, how about we pee on it?"

"I strongly disagree!"

Lin Congfeng insisted on rejecting this rather inferior, primitive and indecent behavior.

In ten minutes, the two of them happily dug the moist kang noodles, and the efficiency increased by more than ten times, and it took almost no effort.

"Jiu'er, what a big fire you've been on lately."

"That's... It is possible to eat too many compressed cookies. ”

“……………”

It took the two of them less than twenty minutes to clean the hard shell.

Lin Congfeng looked at his hands and felt an urge to die.

He could only hint in his heart now that it was just an illusion, and that his hands were still clean when he returned.

Lin Jiu didn't care, the yellow mud on his hand rubbed himself, and he patted Lin Congfeng's shoulder twice, making Lin Congfeng almost vomit out of his disgust.

When the hard shell was cleaned, a stone slab was revealed.

The surface of the slate is quite uneven, which is also a normal phenomenon.

Generally speaking, the stone slab used as a kang surface will be relatively smooth underneath, and the upper part can be leveled with yellow mud and fine sand, so there are no too strict requirements.

Now two people need to slowly break the slate with a sapper shovel, which is a rather patient and physical work.

It had to be slow and powerful, both to prevent the destruction of what was underneath the slab and to break the slate.

This job was very unsuitable for Lin Jiu, so Lin Congfeng could only do it by himself.

And there is only one tool, and this work dagger is obviously not up to the task.

The slate is not an exaggeration of thickness, but it must be at least three inches thick, and Lin Congfeng can only rely on time to grind it little by little.

The first two hours had passed, and Lin Congfeng's hands had almost lost sensation.

"Are we still peeing on it?"

"Jiu'er, your urine is sulfuric acid."

Lin Congfeng was no longer able to complain, and how could they pee in a short period of time.

Whether it was Lin Jiu or Lin Congfeng, they didn't have any water on them.

This is also a reason why Lin Congfeng is anxious.

Although there will be no major problems in a short period of time, once the time is too long, two people will die of thirst.

Lin Congfeng's hands need a certain amount of time to recover, and no matter how anxious he is, there is no way.

Therefore, he could only let Lin Jiu continue to do it, and he told him thousands of times, but Lin Jiu's first shovel still scared him to death.

But fortunately, as long as Lin Jiu can calm down, this kind of work is not difficult at all.

Lin Jiu's control of force is even stronger than Lin Congfeng's, but his mental strength is far behind.

The two of them alternately work and rest, the efficiency is simply amazing, and the combined strength of Jiucong Feng is really invincible.

In less than seven hours, the slate had been cleared.

At this time, Lin Congfeng's mood had changed from his previous fear to quite peaceful.

Because when the first relatively large gap in the slate was exposed, he already knew what was underneath.

It was a coffin, the same one he had encountered in the ground earlier.

At that time, Lin Congfeng almost threw away the shovel, this scene was too weird, even with Lin Jiu next to him, he still felt a chill envelop his whole body.

Fear, this emotion that was very rare in him, hit him again, and he fell into an ice cave.
