In the video recorder, Zhao Baoxuan is squatting on the ground to fill the sealed bag with soil, and under the sealed bag, there are two faint bright spots the size of sesame seeds, which are fleeting.

If you don't look at this picture repeatedly, it's almost impossible to notice if no one prompts it.

"I saw it when I was looking at it on my hand," Lao Liang explained: "The phone is out of battery, and I watched it almost ten times in the VCR, and I pressed the pause button to stop here." ”

Zhao Baoxuan was holding the work clothes she had just found in her hand, and was hesitating whether to put them on or put them on, and when she saw this picture, she immediately put her hand into the sleeve of the work clothes.

"What is this? I didn't seem to see anything there!" she saw that her scalp tingled, and the two bright spots were too similar to her eyes, "Did you see anything?"

Wearing a gas mask, her vision was restricted.

Lao Liang shook his head: "When Xiao An was recording there, my attention was on the rope that pulled you, but we didn't see anything at that time, if a small bug or something ran out, it stands to reason that we could all find it." ”

Zhao Baoxuan remembered one thing: "A large group of rats ran out of the construction site some time ago, just like in the movie, a dense large area, and they ran away without a trace in a blink of an eye. ”

Lao Liang said affirmatively: "These two bright spots are not mouse eyes! Aren't you studying archaeology? Do you have any such a statement in such a situation?"

Zhao Baoxuan recalled vigorously: "I was looking at the dial on the air monitor, and the pointer turned so fast, indicating that there would be no rats underneath." ”

Lao Liang: "I was just about to ask this, can your detector detect what kind of gas is underneath?"

Zhao Baoxuan was embarrassed: "You can only measure the amount of fungi in the air." ”

Lao Liang was puzzled: "What is a fungus?"

Zhao Baoxuan was worried: "Mold is a kind of fungus, the underground mold is different from the mold in our lives, the underground mold is closed in a damp and dark environment, we have never been in contact with it, there is no immunity to it, once it is infected, the light one will be chronically poisoned, and the serious one will soon be Oval." ”

"You said the pointer is turning so fast, so the fungus is poisonous?"

"I don't know. ”

"What do you mean I don't know? The detector is broken?"

"It's not bad, it's just that its rotation is not normal, and if the pointer is shaking, it will also float up and down in a similar value range, but when I took a soil sample, I saw it, and it rotated around!

After listening to it for a long time, Lao Liang didn't know what the air detector could measure, so he knew that the detector didn't play a role: "There are no small animals in the construction site, this can be crossed out!

Zhao Baoxuan stared at the freeze-frame picture: "Yes, ghost fire!"

Lao Liang was happy: "Coward, right!"

Zhao Baoxuan blinked: "If it's phosphorus fire, you should be able to smell it, do you smell it?"

"Yes, yes!" Lao Liang wanted to pretend to be afraid, but he didn't pretend to be like it, and he laughed out loud in the next second: "The conditions for phosphorus fire burning are not met at the construction site." ”

Zhao Baoxuan frowned: "Then I can't think of any other possibility." Ahh

She sneezed a little and turned her head to look out the window: "The rain seems to be a little lighter, can you see the tower crane?
