With three superpowers at his fingertips, he could dominate the 1970s.

Jiang Zhiyu thus spent a peaceful and comfortable month.

During the day, I tend to the flowers, play with the cat, and chat with my parents in the courtyard. At night, after everyone is asleep, I quietly retreat into my spatial dimension to refine the residual nuclear radiation within my body. The radiation feels like fine needles piercing deep into my meridians. With each bit I refine, I feel a cool sensation being drawn from between my bones, which is very comfortable.

"Host, your poison-based ability has leveled up again."

Seventeen's voice came from the depths of her consciousness, and the tips of her wings trembled slightly, as if she were happy for her.

Jiang Zhiyu sensed the fluctuations of the poison-type ability within her body, which was a level stronger than before. The toxins flowing in her meridians were more refined and concentrated. In the past, she needed to consciously concentrate when activating it, but now the toxins could surge spontaneously with just a thought.

"Unfortunately, the wood and space elements are still the same; they can't be upgraded."

"Host, have you noticed any new changes after your poison-based ability was upgraded?"

Jiang Zhiyu thought for a moment, then raised her palm. A small ball of dark green light appeared in her palm, with the faint shadow of wriggling vines within it.

"I can now combine wood-type and poison-type abilities to accelerate the growth of poisonous plants and make them more toxic."

Seventeen folded its wings, its tone clearly puzzled: "Host, this sounds a bit like a useless feature, doesn't it?"

"Not at all useless." Jiang Zhiyu's lips curled up slightly. "The poisonous plants that are forced to grow will naturally form a barrier, and the miasma they produce can cover a large area. Would you say that's useless or not?"

"I still don't understand, host."

Jiang Zhiyu rolled her eyes: "Have you forgotten about the aircraft carrier in our space? I've always worried that placing it on the coastline would be noticed by other countries. Once the location for the carrier is chosen, I'll plant these growth-promoting poisonous plants all around it as a barrier, spreading miasma along the coastal defense line to prevent foreign ships from getting close and spying. Anyone who dares to intrude will suffer enough after just a few breaths of miasma."

"That's right, host! How come I didn't think of that!" Seventeen's wings suddenly spread open, trembling with excitement.

"Alright, there's still some radiation left to refine. I'll continue."

Jiang Zhiyu closed her eyes again, her mental energy sinking deep into her meridians, continuing to peel away the radiation toxins embedded in her bones, bit by bit.

......

A few days later, when the last wisp of radiation was completely purified, Jiang Zhiyu exhaled a long breath of stale air. The languidness and icy feeling that had seeped into her bones finally disappeared completely, and her whole body exuded a long-lost sense of ease.

She stood up and walked into the yard, swinging her arms and kicking her legs, her joints cracking and popping.

"I feel like my bones are rusting lately."

"Host, you just can't sit still," Seventeen snorted in his mind.

"You're starting to tease me now?"

"Who was it that kept clamoring to get out of the space?"

Seventeen was taken aback and was about to retort when someone knocked on the courtyard door.

She opened the door, and Zhuge Yunhe stood there, holding a pot of wine in his hand, with a smile on his face.

"Girl, how's your recovery going these past few days?"

"Not bad." Jiang Zhiyu stepped aside to let him in. "You wouldn't come here without a reason, so tell me what's up?"

Zhuge Yunhe sat down on the stone bench and sighed, "Look, all that equipment has been transported back and is stored in a warehouse. Those scientists are staring at it every day, but they can't use it. They call me several times a day, I can't take it anymore. Why don't you go and help them sort it out?"

"They also sent you a batch of bronze artifacts, which I've already placed in the yard next door."

Seventeen muttered to himself, "Host, I doubt we can use the bronze artifacts they collected; they're not from the Eight Palaces."

"It's fine, if you don't need it, you can just put it in your spatial storage."

"Okay, then tell them I'll go tonight."

Zhuge Yunhe nodded, glanced at her again, and lowered his voice: "Girl, you should change your clothes before going out. Your face isn't suitable for showing up in public anymore."

Jiang Zhiyu touched her face and nodded. To the outside world, she had already "retired from the front line due to serious illness." If people saw her lively and energetic, all her previous acting would have been for nothing.

"I see."

Zhuge Yunhe has left.

......

Song Yanzhou had already set out four dishes and a soup on a small table in the courtyard, and waved to her when he saw her come out.

"Come and eat first. The mission is tonight, right?"

"Um."

"After you finish eating, get a good night's sleep. You've just gained some weight recently, don't go through it all again."

Jiang Zhiyu sat down, picked up a piece of food with her chopsticks, glanced at him, and said, "I know, Commander Song, hurry up and eat."

"Zhiyu, I'll be going back to my unit in a week. I've done a great service this time, and I'd like to apply for a transfer back to Beijing so we won't have to live apart anymore."

Jiang Zhiyu paused with her chopsticks, looked up at him, and said, "Okay, this shouldn't be too difficult."

"Yes, with my wife overseeing things, the transfer is much easier," Song Yanzhou chuckled. "That's like living off a woman."

"So, how good is Commander Song's gigolo lifestyle?"

"tasty."

......

That evening, a military jeep quietly drove up to the gate of the courtyard.

Jiang Zhiyu changed into an inconspicuous dark outfit, made simple makeup on her face, opened the door and got into the car.

Song Yanzhou leaned against the car window, peering outside, and asked in a low voice, "Are you sure you don't need me to come along?"

"No need, that place has radiation, you'd better not go. Just stay home and wait for me."

Song Yanzhou rubbed his nose and hummed in agreement: "Okay, I'll stay home obediently and wait, after all, I like being a kept man."

Jiang Zhiyu chuckled, "Alright, stop joking around, I'm leaving now."

The jeep slowly drove away, its taillights disappearing at the end of the alley.

......

The car drove all the way to a mountain on the outskirts of Beijing.

Jiang Zhiyu got out of the car and was in front of a warehouse that was half-embedded in the mountain. Several groups of people were standing at the door, some in military uniforms and some in white coats, all with tense and expectant expressions.

Dean Liu came forward and saw Jiang Zhiyu with an expression as if she had seen a savior.

"My dear aunt, you've finally arrived! I was driven crazy by those old men at the research institute. They come over every day in their radiation suits to touch all this equipment several times a day. I don't know what they're so keen on, but I can't stop them. That's why I bothered you."

"It's alright, I'm here now."

Jiang Zhiyu glanced inside, then turned to the bodyguards accompanying her and said, "You guys wait here."

She walked into the warehouse alone.

It was the same warehouse where the grain had been stored before, but this time it was packed full, with metal equipment arranged in dense rows, and the surface was covered with a visible gray-green radiation halo.

Jiang Zhiyu gasped.

"Wasn't it said that the last batch of 'little days' was coming up? Who's gone all out this time?"

"They really went all out, host." Seventeen was also visibly surprised. "These devices were manufactured in a decent year, so it's probably been deliberately sabotaged. Looks like there were some unexpected gains later."

Jiang Zhiyu didn't say anything more. She sat cross-legged in the center of the warehouse, spread out her spiritual power, and began to absorb and purify it inch by inch.

The radiation from these devices was heavier and denser than that from the ones on the high seas, and the refining speed was significantly slower. She closed her eyes, feeling the radiation toxins being peeled away, devoured, and transformed bit by bit. The poison-based superpower in her meridians was like a greedy snake, constantly devouring the surging energy.

......

When she opened her eyes again, it was already bright outside.

I glanced at my watch; it was 10 a.m.

Jiang Zhiyu stretched her stiff neck and slowly stood up. That familiar coldness and heaviness returned, but it was much lighter than before, at least still within her tolerance.

The equipment in the warehouse has been thoroughly cleaned, and the metal surfaces gleam with a cold luster, with no trace of residual radiation visible.

She pushed open the warehouse door and went out. Dean Liu and a group of people were still waiting outside, all with heavy dark circles under their eyes, clearly having not slept all night. Seeing her come out, Dean Liu rushed over to her.

"Director Jiang, is everything finished?"

Jiang Zhiyu nodded, her face pale.

"Hey, hey, hey, hurry back and rest!" Dean Liu's voice trembled with excitement as he turned and shouted to the people behind him, "Those old men are reckless; I have to go keep an eye on them!"
