Su Yao and her two companions returned to their base with the supplies they had gathered from the agricultural park. After catching their breath, the system suddenly sent an urgent notification: a batch of extremely valuable energy cores and cold-weather technology data had been detected at the former site of a research institute in the city center. Acquiring these resources would greatly enhance their survival capabilities and stockpiling efficiency in the extreme cold world.

Su Yao's eyes sharpened, and she immediately decided to set off. The city center was far from the base, and the journey was fraught with danger. The snow was several meters deep, and they could only trudge forward through icicles and ruins. The howling wind cut like knives across their faces, and every step forward required tremendous effort.

Halfway through their journey, they encountered a fierce ice storm. The howling winds, carrying sharp icicles, swept in, engulfing everything. Ling Yu quickly erected an ice shield, enveloping the three of them. The cloaked figure chanted incantations, forming hand seals, attempting to stabilize the surrounding spatial fluctuations and reduce the impact of the ice storm. Inside the ice shield, Su Yao focused her mind on communicating with the system, searching for a way to break through the storm.

"There's a weak point in the eye of the storm, but it'll be fleeting. We must seize the opportunity!" Su Yao shouted. Ling Yu nodded, and after Su Yao pointed out the direction, he suddenly exerted his strength, his ice shield transforming into an ice arrow that hurtled towards the weak point. The cloaked figure followed closely, throwing out runes to clear a path for them.

After finally navigating the ice storm, the old site of the research institute came into view. However, it had long been occupied by a group of ice-type mutated beasts. These mutated beasts were enormous, their bodies covered in hard ice armor, and their eyes gleamed with a cold blue light.

Ling Yu charged into the horde of beasts first, wielding his ice sword. The power of the lightning crystal core fused with his ice-based abilities, each strike sparking against the mutated beasts' icy armor. The cloaked figure stood on higher ground, casting wide-range sealing spells to temporarily imprison some of the mutated beasts. Taking advantage of this opportunity, Su Yao used her spatial abilities to traverse the battlefield, searching for the location of the energy core and technological data.

In the basement of the research institute, Su Yao finally found her target. Rows of energy cores, emitting a faint blue glow, were neatly arranged in specially made containers, and the adjacent database contained a wealth of research findings on cold-weather technology. Su Yao quickly stored these precious resources into her system space, secretly rejoicing. If these energy cores could be used in the construction of the base, it would solve the major problem of energy shortages, and the cold-weather technology data might even help them create warmer clothing and shelter.

Just as Su Yao was about to leave the basement, a huge mutated beast leader noticed her movements, broke through Ling Yu and the cloaked man's defenses, and pounced on Su Yao. This mutated beast leader was far stronger than ordinary mutated beasts, and the ice pillars it spewed from its mouth were like sharp blades.

Su Yao remained calm and collected. She retrieved the energy chains she had collected earlier from her system space, instantly transforming them into ice-attribute chains, and hurled them at the mutated beast leader. The energy chains coiled around the leader like serpents, restricting its movements. Seeing this, Ling Yu and the cloaked figure rushed to their aid. Together, the three fought a fierce battle and finally slew the mutated beast leader.

Exhausted and wounded, they embarked on their journey back to base. Upon arrival, Su Yao immediately began studying the cold-weather technology data, while Ling Yu was responsible for installing the energy core into the base's energy system. The cloaked figure assisted, simultaneously using collected materials to repair and reinforce the base's defenses.

After a period of effort, the base underwent significant changes. The energy core provided a stable supply of electricity and heat, and the warm environment freed the survivors from the torment of the bitter cold. Su Yao, using technological data, created new types of warm clothing, far surpassing the warmth of the ordinary clothing they had previously collected. Simultaneously, using materials and tools gathered from the industrial warehouse, they constructed a simple greenhouse within the base and began experimenting with vegetable cultivation.

Although extreme cold still shrouds the world, Su Yao and her two companions' efforts have made their base a beacon of hope on this icy plain. They continue to stockpile supplies and improve the base's strength and survivability, making full preparations to meet future challenges, firmly believing that one day they will be able to rebuild their beautiful home in this desperate situation.
