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

After setting up the aircraft carrier, Jiang Zhiyu walked along the hidden dock to the speedboat, untied the mooring rope, started the engine, and headed into the depths of the bay under cover of darkness.

Seventeen spoke first.

"Host, when do you plan to start setting up the barrier?"

"Right now. The aircraft carrier has already been launched. If the research team starts work and it gets photographed by satellite, it will be a laughing stock."

"So how do you plan to deploy it? I've already removed everything marked on that aircraft carrier! And with their current satellite capabilities, plus the natural terrain advantage, and finally your miasma barrier, they simply can't get a picture of it."

"Better safe than sorry. Tomorrow, we'll have this aircraft carrier anchored behind this island. Even if their satellites pass overhead, we absolutely cannot let them photograph it."

Jiang Zhiyu drove the speedboat to the nearest uninhabited island, tied the boat to the rocks, and jumped aboard.

The island wasn't large, probably only two or three kilometers square. It was covered in wild subtropical shrubs and weeds, rarely visited by humans, and didn't even have a decent road. She stood on a high point and looked around, already having a general idea of ​​what to expect.

"Layered," she whispered to Seventeen. "First, plant tall trees on the outer layer: poison aconite, wax tree, and wild star anise. These three are major producers of toxins. Their canopies can block the view, and their branches and leaves are poisonous; the wind will disperse the poisonous powder. I'll force them to grow to three or four meters tall, and then let the rest grow on their own. This soil is fertile, and the climate is suitable; they'll grow into trees over ten meters tall in less than two years."

She crouched down, placed her palms on the soil, and closed her eyes.

The wood-based power seeped into the soil from his palm, spreading out in all directions like countless fine threads. The underground root system was awakened, and the previously dormant seeds and sprouts grew wildly under the stimulation of the power.

She first laid out poison arrow trees around the edge of the island.

This type of tree is naturally wild in the south, but it normally takes several years to mature. Jiang Zhiyu directly infused it with his supernatural power, and the trunk grew taller and thicker at a visible speed. Milky white sap seeped from the grayish-white bark, and that highly toxic white sap slowly flowed among the branches and leaves.

One, two, three...

She encouraged growth along the outer edge of the island, planting a poison tree every ten meters, forming a dense circle.

Then, step back a few paces and plant wax trees inside the arrow poison tree. The branches and leaves of this tree contain a large amount of urushiol, and if a person walks under it, their skin will become red, swollen, and ulcerated from the pollen. The toxins are slower to develop than those of the arrow poison tree, but the effects are more persistent, making it a second line of defense.

Further in, there are wild star anise.

The fruit and leaves of this tree contain neurotoxins; ingestion can cause convulsions, vomiting, or even death. However, it is not a very tall tree, so it can be planted in the gaps between the first two layers of trees, filling the space of the shrub layer as well.

After urging Jiang Zhiyu around, a layer of fine sweat had already seeped out on her forehead.

Seventeen whispered, "Host, you now have two bodies, so be careful with your power output, don't go too far."

Jiang Zhiyu straightened up and took a breath.

"I know, we'll encourage this round first, and let the rest take root and grow on their own. This area has a subtropical maritime monsoon climate, with an average temperature of around 21 degrees Celsius, a frost-free period of over 300 days a year, and abundant rainfall and high humidity. This environment is simply paradise for these poisonous trees; they'll be able to shoot up on their own in less than one rainy season."

She wiped her sweat, jumped off the high ground, and headed towards the depression on the island.

At the edge of the depression was a natural shallow swamp, overgrown with weeds and buzzing with mosquitoes.

"This is the kind of place where people are most likely to accidentally wander in," Jiang Zhiyu said, squatting by the edge of the swamp and dipping her hand into the muddy water. "We need to add a living fence here."

She first retrieved the seed information of the Gelsemium elegans from the plant atlas in her memory.

The poisonous plant, scientifically known as Gelsemium elegans, is a vine-like shrub. The entire plant is highly poisonous, especially the young leaves and nectar; ingestion of even a single drop can be fatal. She forced the vines to grow, allowing them to twine around the shrubs and shrubs around the swamp, creating a dense, green barrier.

Then comes the yellow azalea.

This shrub produces brilliant golden flowers that are extremely beautiful, but the entire plant contains bark toxins; its nectar, leaves, and bark are all poisonous, and ingestion can cause heart failure. She planted a ring of them around the perimeter of the depression, and when they bloomed, the golden flower wall was a feast for the eyes, but in reality, anyone who touched it would die.

Seventeen clicked his tongue twice.

"Host, you've done a great job! It's incredibly beautiful, but also incredibly poisonous."

"It's not over yet."

Jiang Zhiyu squatted down again and began to encourage the growth of herbaceous plants at an even lower level.

The aconite plant contains aconitine throughout, and its tuberous root is extremely poisonous; even a small leaf can cause cardiac arrest. She planted it in the lowest layer of grass, mixed in with ordinary weeds, so that it was impossible to distinguish without careful observation.

Then comes the Crystal Orchid.

This saprophytic plant is pure white and translucent, growing in dark, damp layers of fallen leaves. It does not photosynthesize and survives on decaying organic matter. It is not very toxic itself, but the environment in which it grows means that the ground has accumulated a large amount of decaying leaves and toxic substances. If a normal person walks here, their feet will sink into the soft, rotten mud, and they will instinctively dare not go any further.

"Add these as well." She urged for several more plants: taro, pinellia, and arisaema, all common poisonous plants in the south, inconspicuous among the understory vegetation.

She laid it out layer by layer, each layer more concealed than the last.

The outermost layer consists of tall poisonous arrow trees and wax trees, their canopies blocking out the sky, resembling a dense subtropical jungle from afar. The second layer is a mixed shrub belt of wild star anise and yellow rhododendrons, reaching chest height; anyone attempting to pass through would inevitably suffer skin abrasions and come into contact with the toxins. The third layer is a network of vines woven from Gelsemium elegans, twining between the shrubs and trees, completely sealing off the gaps in the middle layer. The bottom layer is a carpet of aconite, monolocorata, and various saprophytic plants, covering the ground; stepping on it leaves only mud and poisonous leaves.

Four layers of lockdown, each interlocking with the last.

Jiang Zhiyu retreated from the island, returned to the speedboat, drank a large mouthful of spiritual spring water, and rested for a while.

Seventeen sighed in his mind.

"Host, you're amazing! All the fallen leaves and branches accumulate in this enclosed bay environment, and with the high temperature and heavy rainfall, they decompose quickly, soon forming a basic white fog barrier."

"This is just the beginning." Jiang Zhiyu leaned against the side of the speedboat, looking at the scattered islands around them. "Consider the climate here: a mid-subtropical sea monsoon climate, with an average annual temperature of around 21 degrees Celsius, a long frost-free period, abundant rainfall, and humidity consistently above 80%. This environment is practically a natural greenhouse for these poisonous plants; their growth will only be more frenzied than anything I could force."

"Moreover, this is a closed bay with a narrow opening and a large interior. Dongchongkou is only 2.6 kilometers wide, surrounded by hills and mountains on all sides. The miasma cannot dissipate and can only accumulate in the bay. In addition, this area is naturally rainy and foggy. The natural fog and the toxic miasma I have created will mix together, and in less than half a year, the entire outer perimeter of the bay will be completely shrouded in a white fog."

As she spoke, she started the speedboat and headed towards the next island.

"The key is that I only sealed off the uninhabited islands on the outer perimeter; the research area and camps inside the bay remain unaffected. People inside can move around as usual, breathing normal air."

Seventeen continued, "That's right, host. Think about it, this combination of dense fog and miasma, when a satellite passes over it, it just looks like a white blur, you can't even see the terrain outlines clearly, let alone identify if there's an aircraft carrier docked inside."

"That's exactly what I calculated." Jiang Zhiyu's lips curled slightly. "Satellites can't see it, reconnaissance planes can't fly over, and spy ships dare not approach. Three layers of protection are enough."

The speedboat headed towards the second uninhabited island.

This one was larger than the previous one, with a more complex terrain, featuring ridges and valleys, and denser vegetation. Jiang Zhiyu climbed onto the island and stood on the ridge, looking down.

The conditions here are better, saving some effort in stimulating growth. Many poisonous trees already have wild individuals, but they are not dense enough. What she needs to do is to stimulate the growth and density of these scattered poisonous trees, and then fill in the missing varieties to connect the entire blockade line.

She worked until dawn.

Only when the faint morning light shone on her face did sweat drip down her chin and onto the soil.

Seventeen reminded her, "Host, you've already produced enough output today, don't push yourself any further."

"Hmm, that's about it." Jiang Zhiyu looked around. The main uninhabited islands had been surrounded by four layers of blockade. The remaining minor details could be left to the plants to grow on their own. In a few months, they would connect into a whole.

She drove the speedboat back to the camp dock, moored the boat, wiped the sweat from her face, and headed towards the dormitory, hoping to get some more sleep.
