Shimijing thought more than Lu Zhi'an expected, the further down, the quieter it became, and in the end, it seemed to have traveled through time and space to another world.

Earlier, Shi Ning and the engineer whispered technical terms that he didn't understand at all, all of which were related to the soil layer, and sometimes mentioned metal elements, which belonged to Shi Ning's field, a field that was completely unfamiliar to him.

Time passed little by little, Lu Zhi'an always guarded silently, and he didn't know how long it took, he saw Shi Ning, who had been lying on his stomach, slowly moving again and re-extracting the soil, Lu Zhi'an looked at the time, and it was already an hour and a half since they came down.

And for the next three consecutive days, every time he came up, Shi Ning's expression was extremely serious, and he communicated with the engineer in a low voice, and it seemed that the progress was not going very well.

"If you don't have it today, if you haven't already, you're just afraid of ......" The engineer looked at the displayed metal test floating table and said with a solemn expression: "Either the position is biased, or there is no material we need." ”

Shi Ning was originally very sure, but after failing to sample for three consecutive days, her heart gradually became a little bottomless, and she even had doubts about where she was.

Could it be that the Garrel where she is not the Garrel she has been to before?

Like, her home in Nine Cities only exists in her original world, not the current world?

"Try again tonight, if there is no ......" Shi Ning pursed the corners of his mouth lightly, his expression was a little gloomy, "Perhaps, not here." ”

If not, then they need to find it again, or maybe she will work on a new type of material to replace the one they need to find.

The core is re-developed, which is easier said than done!

The engineer heard the frustration in Shi Ning's tone, and he smiled: "Don't worry, we often encounter this matter." Sometimes wait a minute, and the willows and flowers will brighten up another village. Come here today, go back to your room and have a good rest, and we'll go down in the evening! ”

Not knowing how much material was needed, the engineer was able to comfort Shi Ning.

Shi Ning can only comfort himself like this, hoping that the willows will be bright and another village.

Walking out of the laboratory, she saw Lu Zhi standing quietly in front, and as soon as she came out, his eyes immediately fell.

Shi Ning smiled and quietly looked at the boy waiting beside him, he had worked hard these days, and he was so busy that he didn't have time to talk to him.

"Are you tired?" Lu Zhi'an approached, raised his hand, gently brushed the hair that the wind blew in front of her eyes, pinned the hair behind her ear, and saw her thick dark circles under her eyes, and the bloodshot in her eyes, Lu Zhi'an's mouth throbbed, "Rest when you're tired." ”

Shi Ning said softly: "Lend me a shoulder to lean on." Failed again, and the fatigue of her body could still be withheld, but the pressure like a mountain pressed her to the point that she couldn't breathe.

The project of the scientific research group was started because of her, the deep mining industry was drilled because of her, Fang Gong and Yan Gong were waiting for her good news, everything started because of her, if the core materials were not found this time, how could she explain?

Lu Zhi'an squatted beside her, "Lean on my back to rest." ”

How tired it is to rest while standing, it is better to let him carry it on his back and carry it back to his room to rest.

Shi Ning was not polite, he came up from the well at two o'clock in the morning last night, and now it is more than four o'clock in the afternoon, and he has not rested for almost fifteen hours, so he is a little tired.

Carried by him, Shi Ning closed his eyes, letting his tense cranial nerves gradually relax.
