Before the apocalypse.
Xu Zhengyang had once completed a mission called "Smokeless Gunpowder," which required him to collect thirty tons each of cotton, nitric acid, and sulfuric acid.
At that time, the Blood Plague had not yet broken out, society had not collapsed, and the rule of law was still intact.
Back then, the easiest material to obtain was high-quality cotton—all it took was money.
However, nitric acid and sulfuric acid were controlled substances, so Xu Zhengyang had to secretly purchase them in Siam.
But after the apocalypse struck, the situation reversed entirely.
With the arrival of the Blood Plague, factories worldwide had shut down, and Xu Zhengyang could easily obtain sufficient nitric acid and sulfuric acid from any factory he visited.
Even the equipment used to produce nitric acid and sulfuric acid.
Xu Zhengyang could dismantle and bring back to his shelter, where he planned to build separate production workshops for both acids.
On the other hand, cotton, which had been the easiest to obtain before the apocalypse, now posed a significant challenge for Xu Zhengyang...
Even the fastest-growing cotton varieties required 110 days to fully mature.
Moreover, cotton yields were low, with only about 120 kilograms produced per acre.
Given such low productivity.
If Xu Zhengyang were to allocate a section of the shelter's agricultural area for cotton cultivation, it would waste too much valuable space! Just then.
Xu Zhengyang suddenly thought of something and immediately said to Da Bai, "Da Bai, pull up the satellite view of the cotton production area in Xinjiang Province!"
"Understood, Master."
Da Bai complied, synchronizing the real-time satellite footage to Xu Zhengyang's contact lenses.
"Perfect!"
Xu Zhengyang was overjoyed when he saw the real-time satellite images! Xinjiang Province was vast and sparsely populated.
As a result, it was one of the least affected areas by the Blood Plague Virus.
Additionally, Xinjiang was far from the coast, so it had not been attacked by the Blood Plague monsters from the sea.
Combined with these factors.
Xinjiang had become one of the few remaining havens on Earth! Cotton was inedible.
So the massive cotton production area in Xinjiang, now untended, had begun to grow wild weeds.
Looking at the vast cotton industrial park in the real-time satellite images, Xu Zhengyang was thrilled! He immediately went to his computer.
Using the engineering knowledge he had acquired from a previous knowledge card, he began designing various agricultural machines for planting and harvesting cotton!...
A short while later.
Xu Zhengyang handed the completed designs to Da Bai and said, "Da Bai, allocate part of our production capacity to manufacture these cotton planting and harvesting machines.
Then send me the locations of the recently built nitric acid and sulfuric acid factories. I'll go retrieve the equipment!"
"Understood, Master."
Da Bai acknowledged and projected a map onto Xu Zhengyang's contact lenses, complete with navigation routes.
...
With the speed of the shuttle and Xu Zhengyang's current mechanical army.
It took him only half a day to bring back all the equipment and raw materials needed to build the nitric acid and sulfuric acid production workshops, storing them temporarily in the shelter.
Once Da Bai completed the construction of the workshops, production could begin immediately! The more complicated issue was the cotton industrial park.
Although Xu Zhengyang had already restored production in the cotton industrial park using the new robots he had designed.
Two mixed combat teams were dispatched to protect the cotton industrial park from Zombies and those with ill intentions.
However, the power system in the province had already collapsed.
Therefore, Xu Zhengyang had to travel to the province daily to recharge his various robots, ensuring they didn't turn into scrap metal due to energy issues...
...
Although it was somewhat troublesome.
Fortunately, the issue of raw material supply for smokeless gunpowder was smoothly resolved. As long as Xu Zhengyang could solve the problem of ten special types of ammunition.
He could successfully complete this task and obtain the reward: the [Super Spacetime Teleportation Platform], which looked anything but simple!
Fortunately, the special ammunition only differed slightly in the materials and processes used for the bullet heads, with most of their primers being universal.
So, as long as Xu Zhengyang solved the raw material supply issue for the bullet heads, he could successfully complete this task!
Thus, Xu Zhengyang asked Da Bai, "What materials are still needed to produce the ten types of special ammunition?"
"Master, which ten types of special ammunition do you want to produce in the shelter?"
Da Bai said.
Projecting a series of text messages onto Xu Zhengyang's contact lenses, detailing what kinds of special ammunition various raw materials could produce:
[White Phosphorus: Can produce white phosphorus bombs, smoke bombs, illumination bombs]
[Tungsten: Armor-piercing shells, shaped charge shells]
Not a single mistake, every piece of content is in the 69 book bar to see!
...
All in all.
Da Bai listed about ten lines of text information for Xu Zhengyang.
After the apocalypse descended.
These raw materials were not hard to come by. As long as Xu Zhengyang was willing, he could easily bring a large batch back to his shelter at any time.
If Xu Zhengyang wanted to maintain a stable supply of materials for his shelter.
He would have to carry the Dimensional Space Pocket and fly around the globe daily in a shuttle...
"Forget it, flying it is."
But Xu Zhengyang had no better solution at the moment, so he said to Da Bai, "First, let's see where there's a white phosphorus factory. I'll get some white phosphorus first!"
...
In the next half day.
Xu Zhengyang traveled around the country and finally gathered enough materials to produce all the special ammunition needed.
When his ammunition production workshop was running at full speed, producing over ten thousand rounds daily.
A series of system subtitles finally appeared before Xu Zhengyang's eyes: [Main Quest: Ammunition Reserve (Completed)]
[Reward Obtained: Super Spacetime Teleportation Platform]
...
[Super Spacetime Teleportation Platform]
[Skill]
(Super Spacetime Teleportation: The Super Spacetime Teleportation Platform can simultaneously set up multiple teleportation gates with a maximum range of 3000 kilometers)
[Note: Installing the Super Spacetime Teleportation Platform requires a three-dimensional space of 36010120 meters]
After seeing the detailed attributes of the Super Spacetime Teleportation Platform, Xu Zhengyang was overjoyed! With this thing.
Xu Zhengyang only needed to install it on the surface of the shelter, and it would be incredibly convenient for him to collect resources later! So Xu Zhengyang did not hesitate.
He immediately had Da Bai clear out enough space on the surface of the shelter and then installed the Super Spacetime Teleportation Platform there!
It was a giant door frame full of sci-fi vibes! When the photon towers supplied it with enough energy, the operation end of the Super Spacetime Teleportation Platform, like the magic door in Howl's Moving Castle, displayed a series of binding coordinates.
All Xu Zhengyang had to do was press the button.
The Spacetime Teleportation Platform can connect to the bound coordinates at any time, enabling teleportation between the shelter and the bound locations! The teleportation range of the Spacetime Teleportation Platform is not only six times farther than the teleportation gate Xu Zhengyang previously obtained but also reaches an astonishing 3,000 kilometers!
