"And these too, one bottle for each person, just in case."

Having finally found the relevant medicine, she breathed a slight sigh of relief and then had the zombie security guards deliver some of the targeted medicine to Lin Xiaoduo in the safe zone.

Thanks to the free purchase program, this kind of medicine is simply unavailable in today's world.

"Wait a minute... let me sort it out again." Zhang Xiaojuan gripped the medicine bottle, suddenly becoming unusually serious.

"Teacher Xu, when you told us to close the door just now, did you already know that Lin Xiaoduo was affected by nuclear radiation?"

Xu Yi pushed up his gold-rimmed glasses. "It's just a guess, I can't be sure."

“So you… rushed in without wearing protective gear…” Sun Tiantian’s expression froze, and she secretly glanced at Lu Sheng out of the corner of her eye. “That was so dangerous…”

"Teacher Xu, are you out of your mind?"

Her words reflected the sentiments of everyone present.

Knowing that Lin Xiaoduo might be carrying a deadly source of radiation, Xu Yiming immediately ordered everyone else to retreat back to the villa, and then, without any protective measures, took Lin Xiaoduo to a location far away from the villa by himself.

“If Lin Xiaoduo really has a radiation source on her, medical protective clothing won’t be very effective; only military NBC protective equipment will work. In this emergency, we can only move her to a location where you won’t be exposed to radiation.” Xu Yi smiled nonchalantly.

"I'm impressed by that reaction and courage!" Zhang Xiaojuan gave Xu Yi a thumbs up with admiration.

Han Rui's eyes sparkled, "Teacher Xu, you really... I'm going to cry!"

In such an emergency, how strong must one's heart be to make a quick judgment and choose to sacrifice oneself to save the situation?

Lu Sheng stared at Xu Yi's handsome profile, and a sudden surge of anger rose in her heart for no apparent reason.

This guy really doesn't value his own life.

"Could Lin Weicheng's sudden outburst and kicking Lin Xiaoduo out of the base be related to nuclear radiation?" Xiao Yu finally noticed something amiss. "I thought he was quite doting on his sister before, so he shouldn't have gotten so angry over a bowl of corn porridge."

“I asked Lin Xiaoduo, and she didn’t notice anything unusual throughout the whole process.”

Xu Yi frowned slightly, his expression turning serious once again. "It's impossible to determine the specific source of radiation, since the smallest radiation source can be only the size of a keychain, making it completely undetectable."

The truth may only be found at the Tengfei Base.

After a harrowing thirty minutes, the group re-inspected the entire base and disinfected the room where Lin Xiaoduo had stayed the previous night.

Xu Yi monitors Lin Xiaoduo's body radiation levels daily and provides her with treatment.

Fortunately, Lin Xiaoduo's ability level was raised to the fourth level after an unexpected stimulus, and her physical fitness underwent a qualitative change, which allowed her to escape from the brink of death.

Originally, Lu Sheng only allowed the zombie security guards to provide Lin Xiaoduo with water and food every day out of humanitarian considerations for the temporary tenants of the base, but the situation has changed in the last few days.

When Rocket retrieved the mutated bighead fish from the stream outside the safe zone for the nth time, Lu Sheng and the others finally realized the seriousness of the situation.

"This fish... is so weird..." Han Rui kicked the strange fish with two heads and two tails aside in disgust.

Sun Tiantian looked at Lu Sheng with concern, "Recently, we've been seeing multi-headed fish or animals dying outside the safe zone every day. The Tengfei Base is upstream of this river. Could the radiation have already spread to our area?"

Nuclear radiation is colorless and odorless. Even though Xu Yi conducts environmental monitoring every day, it is still possible for it to slip through at any time.

Moreover, if the water pollution concentration exceeds the standard, the safe zone near the base will also be affected by water seepage.

However, there is currently no option to relocate the base within the system, so Lu Sheng has no way to move the base.

"We need to go to the Tengfei base to remove the radioactive source."

They will be safe downstream only if the radioactive source is completely buried.

“But even the downstream rivers have been affected. The Tengfei Base is now definitely Chernobyl 2.0. How are we supposed to get there?” Xiao Yu asked worriedly.

Military nuclear protective suits, such hardcore equipment, never entered the market before the apocalypse.

The supplies Lu Sheng collected only included simple medical protective suits, which were negligible in such a heavily polluted area.

"I'm going to the K3 base." Lu Sheng immediately stood up.

The K3 military should have an equipment depot. Last time she gave Ma Dongmei several hundred tons of corn kernels, so it wouldn't be unreasonable to exchange them for a few sets of military protective clothing, right?

After arriving at K3 and explaining his purpose, Su Zheng looked troubled.

“Our armory doesn’t have protective suits. The only place in the entire city of H with them is the suburban reserve area, but that area has already fallen.”

Lu Sheng raised an eyebrow. "Give me the address, I'll come get it."

"I'll go with you," Su Zheng said, already getting up.
