The Chosen System: Counterattack with Husband

Lin Yi lowered his head and pondered for a while, then asked Rong Yan a question he had thought about before entering the mine.

"Rong Yan, since these unknown crystal minerals have affected your and Mr. Xu's vision, is it possible that they have a certain amount of radiation hazard?"

As soon as he said this, Rong Yan's eyes lit up. He immediately took off his backpack and took out an instrument that looked like a simple calculator.

After turning on the switch of the instrument, Rong Yan held it and walked a distance tentatively into the mine.

But soon, he frowned almost imperceptibly.

Xu Yiyu noticed the expression on Rong Yan's face. In addition to confusion, there seemed to be a bit of...

Disappointed?

"Captain Lin, unfortunately, my portable radiation meter doesn't have any readings."

Rong Yan walked back and showed the clean display screen of the instrument to Xu Yiyu and Lin Yi, with a hint of regret in his tone.

"If these crystal minerals have radiation that is unknown under current technological conditions, this instrument cannot detect it."

As soon as Rong Yan's regretful words came out, Xu Yiyu's mind suddenly lit up with an idea, and he thought of a possibility that sounded a little far-fetched.

"Is there a possibility that these crystal minerals are indeed radioactive as Captain Lin guessed? But Xiao Yan, didn't you say that you can neither recognize the material composed of this crystal mineral nor the instrument can read the readings to identify it?"

"Then could it be... a type of radioactive mineral deposit that has not yet appeared in the public eye on the Blue Planet?"

The location of this underground palace is too subtle. If it really contains the imperial seal, but the site is not in China, then the purpose and intention of the builders are indeed worth considering.

Perhaps in addition to hiding treasure, the builders chose to build the underground palace here in order to prevent the crystal mine from being exposed to humans too early?

As if he was thinking of something, Rong Yan's expression suddenly became serious. He quickly opened his backpack and began to look for something in it anxiously.

Verbally, he also did not forget to remind Xu Yiyu and Lin Yi.

"I remember that Mr. Tianlin prepared some gas masks and radiation-proof gloves. Hurry up and take them out and put them on. Don't expose yourself to radiation for too long!"

Rong Yan from the theory group had his reasons for any reminders he issued. Xu Yiyu and Lin Yi did not waste any time and immediately opened their backpacks, took out gas masks and anti-radiation gloves, and equipped themselves as quickly as possible.

"Although we don't know whether the radiation from this crystal mine will have long-term harm to the human body, we have just walked in the mine for so long that even my and Sister Yi Yu's vision has been affected. It is best not to continue to be exposed to this environment, otherwise it may not be as simple as hallucinations."

Rong Yan skillfully put on anti-radiation gloves, and explained the dangers of radiation as clearly as possible at the fastest speed, hoping that his two companions would pay more attention to radiation rays.

Xu Yiyu never questioned Rong Yan's professionalism.

He said so, so she did as he said.

Although she remembered that there were full-body protective gear for radiation environments in her system mall, not to mention that Tongzi was still being updated, it was obviously impossible for her, Xu, to inexplicably take out something in front of her two companions and say that this could ensure everyone's safety.

Apart from anything else, as an outsider who had no previous knowledge of chemistry, her words were not convincing at all.

After all three of them were equipped with gas masks and anti-radiation gloves, they tacitly pulled their clothes tighter. Xu Yiyu also pulled up the hood of his coat to minimize the exposed area of ​​his skin.

Looking at Rong Yan through the gas mask, Xu Yiyu could still hear the heavily-armed young man heaving a sigh of relief.

"Huh... After we get out of here, we'd better do a comprehensive inspection. Some of the radiation rays known on the Blue Planet are very harmful, so we can't take it lightly."

Rong Yan's voice was a little muffled through the mask, but Xu Yiyu could clearly feel the seriousness in his words.

She would not think that Rong Yan was overreacting, but would rather appreciate her companion's rigor and prudence.

After Xu Yiyu and Lin Yi nodded to Rong Yan, they turned around and looked at the darkness at the end of the mine, which was illuminated by a faint silver-white light.

Although this little light could not illuminate all the details, it was enough for the three people to roughly see what was in the darkness through their masks.

——This is a spiral staircase about one meter wide that goes upward, like the tower where the princess lives in a fairy tale. There are torches for lighting on the walls on both sides, which are spaced far apart.

But other than that, there wasn't even a window.

Due to the obstruction of the mask, Xu Yiyu's vision was somewhat affected, but he could still see that the slope of this spiral staircase was quite steep, and the height difference between each step was also quite large.

When Lin Yi walked to the spiral staircase, she roughly estimated the height of the stone steps based on Lin Yi's height.

The height of the first stone step is almost up to Lin Yi's knees, which is nearly 50 centimeters!

There is no end in sight for the spiral staircase, but the stone steps currently exposed to the three people's vision are basically at the same height as the first step.

——Nowadays, such a design is almost against common sense.

Xu Yiyu was not the only one who noticed this. Rong Yan, who had a wide range of knowledge, and Lin Yi, who had rich experience in handling cases, also observed it.

"In China's current civil buildings, the height of the steps is generally no more than an adult's ankle. Stone steps of this height... really don't look like they were designed by modern people."

Lin Yi looked up at the corner of the stone steps, his resolute brows slightly furrowed, and there was some doubt in his tone when he spoke.

"Although there were many tall people in ancient China, the average height of adult men was only about 167 centimeters until the Ming and Qing dynasties. Knee-high steps were really rare."

Rong Yan also walked to Lin Yi's side, leaned forward to take a look at the top of the spiral staircase. Although his tone was calm, it was clear that he couldn't believe what he saw.

Xu Yiyu walked behind the two of them, raised his hand and patted their shoulders, and spoke in a deliberately relaxed tone.

"In any case, this is the only way forward for us. Even if we don't want to lose weight and ruin our knees, we may have no choice."

There are many things in this underground palace that go against common sense, and she doesn't intend to delve into them one by one.

As for the archaeological undertaking, we can wait until everyone in the treasure hunting team has gotten out safely, and then ask other people with better equipment to carry it forward.

At that moment, Xu Yiyu did not act pretentiously. He took a step forward with his long legs and bravely stepped onto the first stone step.

She stood on the stone steps and turned around with a smile on her face. With a slightly exaggerated gesture, she extended her hand toward the two companions behind her, and pretended to be mysterious by lowering her already slightly low and mellow voice.

"You two, do you want to join me on the journey to heaven?"
