Su Yao knew that relying solely on supplies would not be enough to survive in the apocalypse for long; improving her family's combat capabilities was the key. Therefore, she tailored a strict training plan for her parents.

Every morning, as the first rays of sunlight fall on the scorching earth, Su Yao leads her parents in physical training in the courtyard of the safe house. Her father practices push-ups and pull-ups, while her mother does squats and jump rope. Although the high temperature makes each movement incredibly difficult, and sweat pours down like rain, they grit their teeth and persevere.

"Come on, Dad! Do ten more!" Su Yao encouraged him from the side.

"Mom, your posture is perfect, keep it up."

Building upon physical training, Su Yao began guiding her parents to perceive and utilize the supernatural abilities within their bodies. She instructed them to close their eyes and calm their minds to feel the subtle energy within their bodies.

"Try to gather this energy in your palm," Su Yao said softly.

The father reacted first; a faint light emanated from his palm, and a look of surprise appeared on his face. "Yaoyao, I did it!"

Not to be outdone, the mother also successfully developed supernatural abilities after some effort.

As her parents' supernatural abilities awakened, Su Yao began practical combat training. She used her abilities to create virtual zombie models so her parents could practice their attack techniques.

"Attack the zombie's head or heart; those are their weak points," Su Yao instructed, observing her parents' actions.

The father's strength-based superpower was put to full use in the battle; he swung his arms and repelled the approaching zombie models one by one. The mother, on the other hand, used her healing superpower to replenish the father's strength and treat his wounds.

However, during one training session, an accident occurred. In an attempt to increase the difficulty, Su Yao accidentally summoned a real, high-temperature mutated zombie. This zombie was enormous, with skin as hard as rock, and emitted a foul stench as it lunged at them.

"Watch out!" Su Yao shouted, rushing forward first. A supernatural longsword appeared in her hand, and she stabbed it fiercely at the zombie's head. But the zombie reacted extremely quickly, dodging the attack with a sidestep, and then swung its arm back, knocking Su Yao back several meters.

Seeing this, the parents quickly joined the fight. The father used his supernatural powers to enhance his body, grabbing the zombie around the waist and trying to throw it to the ground. The mother, meanwhile, cast a defensive shield on the father to reduce the damage from the zombie's attacks.

With the combined efforts of the three, the zombie was finally eliminated. Su Yao wiped the sweat from her forehead and said, "I was careless this time, but it also showed us our shortcomings. We need more training."

In addition to training, Su Yao also set up various defensive traps around the safe house. She buried ability-sensing landmines in the ground, which would explode if any foreign object approached. Above the walls, she installed laser beam devices capable of attacking invading enemies.

Meanwhile, Su Yao didn't forget to prepare for the acid rain crisis. She covered the roof of the safe house with a special rainproof material that could resist the corrosion of acid rain. She also prepared a large amount of alkaline solution inside the house so that anyone who accidentally came into contact with acid rain could be cleaned up immediately.

As time went on, her parents' supernatural abilities grew stronger, and their teamwork became increasingly seamless. But Su Yao knew that this was far from enough. In this apocalyptic world, danger lurked everywhere, and they had to constantly improve themselves to survive the impending acid rain disaster.
