Su Yao moved cautiously through the thick fog, each step taken with extreme care, as if venturing into an unknown minefield. The fog, like a thick ball of cotton, completely obscured her vision, limiting her visibility to just a few feet.

She tried to activate the system's scanning function, but the high concentration of dangerous energy severely interfered with the system, allowing her to obtain only occasional, blurry information. Suddenly, a slight buzzing sound rang in her ears, and Su Yao immediately became alert, using her spatial ability to make herself invisible.

A swarm of fist-sized flying insects emerged from the thick fog. Their bodies had a metallic sheen, and their wings vibrated at an extremely high frequency, generating a strange energy fluctuation as they flew. These insects hovered for a while where Su Yao had just stood, seemingly searching for a target, before flying off in one direction. Su Yao breathed a sigh of relief and quietly followed behind the insects, guessing that they might lead her to some useful clues.

After following the flying insects for a while, the thick fog ahead gradually thinned, and a huge building appeared before them—the secret warehouse they had been searching for. The warehouse doors were tightly closed, and there were some strange devices around it, constantly flashing lights, seemingly some kind of defense system.

Just as Su Yao was about to approach the warehouse, the flying insects suddenly turned back and swarmed towards her. Realizing she had been discovered, Su Yao quickly activated her wind blade ability, slashing down the approaching insects. However, the insects were numerous, attacking wave after wave. Su Yao fought off the insects' attacks while making her way towards the warehouse door.

As she arrived at the gate, the system prompted: "The gate's defense system has been detected to be connected to an energy magnetic field. You may attempt to sever the connection point using your special abilities." Su Yao began to carefully observe the devices around the gate and discovered several key energy nodes. She concentrated, merging her spatial and fire abilities, and attacked the energy nodes.

After several attempts, the connection between the defense system and the energy field was finally successfully severed. The door slowly opened, and a musty smell wafted out. The warehouse was filled with various boxes and shelves, storing a large amount of high-tech equipment and medical supplies. Su Yao was delighted.

However, at that moment, heavy footsteps echoed from inside the warehouse. A massive mechanical puppet emerged from the shadows, its body forged of steel, its joints gleaming red, and its head adorned with enormous eyes that radiated a chilling gaze. The mechanical puppet raised its massive fist and slammed it down towards Su Yao.

Su Yao used her spatial ability to teleport to the side, then unleashed her fusion ability to attack the mechanical puppet's legs. However, the puppet's defenses were extremely strong, and her attack only left some shallow marks on its surface. The mechanical puppet turned and attacked Su Yao again, each attack causing the ground to tremble violently.

While dodging, Su Yao noticed that the mechanical puppet's movements were somewhat sluggish, seemingly due to prolonged disuse and some rust in its joints. Seizing the opportunity, she used her spatial abilities to get behind the puppet, then concentrated her fire energy and launched a powerful attack on its joints. After a series of attacks, one of the puppet's joints was finally damaged, and its movements became even more sluggish.

Su Yao pressed her advantage, continuing to attack the mechanical puppet's other joints while dodging its counterattacks. After a fierce battle, the mechanical puppet finally collapsed. Su Yao wiped the sweat from her brow and began collecting supplies from the warehouse.

She used the refrigerated storage space to store boxes of medical supplies and high-tech equipment, which would greatly enhance their ability to survive in the apocalypse. Just as Su Yao was collecting supplies, the system suddenly notified her: "Energy reaction detected below the warehouse; there may be more important items."

Su Yao hesitated for a moment, but ultimately decided to go down and check. She found a staircase leading down in a corner of the warehouse and carefully descended. Below the stairs was a basement, in the center of which sat a huge energy crystal, emitting a soft glow, surrounded by complex instruments.

Su Yao approached the energy crystal, and the system displayed: "This is a crystal that can purify and stabilize energy, and it is extremely effective in eliminating interference from energy magnetic fields." Su Yao realized that this was a treasure, so she carefully put the energy crystal away and left the basement.

When she emerged from the warehouse laden with her spoils, her family cheered. Looking at their excited faces, Su Yao knew the adventure had been worthwhile. They set off on their journey back to the safe house, carrying the supplies; in this apocalypse, they now had another guarantee of survival.
