There was no light in the basement, until two or three meters away, there was a luminous rod lit up, and in the dim light, Zhou Lao looked, he saw the steel door that the sacrificial compatriots closed at the last moment.

His eyes suddenly lit up, Zhou Lao held his heart beating wildly, and walked over firmly step by step when the steel door opened without a little hesitation.

When the steel door opened, Gu Chen and Zhou Lao understood why the engineers inside could withdraw immediately, it turned out that behind the steel door was the elevator, and the elevator was the way to the basement at the bottom.

pressed the elevator button, and saw that Zhou Lao's pace was steady, so he didn't reach out to help.

"Thanks to someone this time, otherwise, we wouldn't have been able to get in." The elevator is still operating, and the wires and pipes here are secretly laid by the Chinese engineering regiment, so as long as the wires are not damaged, all the circuits can work.

There are only two floors in the basement, and when the elevator doors open, the auto-sensing lights are all turned on.

Gu Chen stopped and said calmly: "Old Zhou, I'll leave it to you inside, and I'll leave it to me outside." ”

The wind is light, not shocked, like a glass of water, with its clarity and its charm.

Bringing the most important fighter research engineer of this operation into the basement, Gu Chen didn't even hurry to take a look at what was inside and left in a hurry, she needed to bring Xie Jingyao over immediately, this may be Zhou Lao's deputy.

Xie Jingyao's mental quality was quite good, and when Gu Chen returned, he handed over a cup of coffee with a moderate temperature, "Highly guarded for four hours, this cup of coffee can hopefully keep you awake at any time." ”

He didn't ask her if she sent Zhou Lao to the basement safely, nor did he ask her if she encountered any danger during the operation, he didn't ask anything, there was a shallow smile on his handsome face, he sat on the desk in the room, and his casual posture was graceful and uninhibited.

Gu Chen never needs to rely on this kind of refreshing thing to keep the brain clear, Xie Jingyao saw the rejection in her eyes, hooked the corners of her mouth, and said: "An appropriate amount of caffeine will stimulate the cerebral cortex, promote sensory judgment, memory, and emotional activities, make the myocardial function more active, vasodilated blood circulation, and improve metabolic function." At the same time, caffeine can also reduce muscle fatigue and promote the secretion of digestive juices. ”

He didn't have a general understanding of coffee, Gu Chen glanced at him with a smile, "Have you worked on coffee?" ”

"No, I'm the owner of the coffee." Seeing the smile in her eyes, Xie Jingyao breathed a sigh of relief lightly and didn't let her notice it.

If it was any of the Tigers' teammates to escort Zhou Lao tonight, he would definitely not be as nervous as he was just now. Gu Chen, to him, there are only a few numbers, and he knows very little.

The most important thing is that the two-player mission must have a very high degree of tacit understanding between comrades-in-arms and comrades-in-arms, which is the tacit understanding accumulated in the battle after years of getting along with each other.

And even if he and Gu Chen have fought together once or twice, they will cultivate a little tacit understanding, but no, they have never fought side by side, and she is a stranger to him.

Let him believe in a strange comrade-in-arms who has no tacit understanding, no matter how good his psychological quality is, there will be mood swings.

Gu Chen came back safely again, Xie Jingyao knew that he had to unconditionally believe in the comrades-in-arms who were now fighting side by side with him, and he couldn't subconsciously think that it would be more dangerous for the sake of her being a woman, he needed to be more vigilant.
