Cave Refuge

Due to the sudden onslaught of the electromagnetic pulse, the nearby vessel that was preparing to dock at the harbor experienced issues with its onboard electronic devices. In a panic, the crew could only manually activate the emergency switch and immediately dropped anchor.

Pengville Port was a major port, and there were many ships drifting nearby. So, when Dong Tianyu left the water surface, the required survival points for the upgrade of the cave mansion decreased by 300 once again.

After going through one upgrade of the cave mansion, Dong Tianyu found that not only did the required survival points for another upgrade increase, but the number of survival points for decomposing and absorbing the same kind of material also decreased.

According to the previous situation, even if the upgrade requirement had doubled, Dong Tianyu was now collecting far more resources than before.

Not to mention, the amount of steel alone from the boats he has harvested from the water was already more than what he obtained from a single warehouse in the past.

Adding on the cargo in the ship cabins, today's loot far surpassed what he could typically gain in a week.

If Dong Tianyu had come here earlier, the speed of the cave mansion's upgrade was bound to be a lot faster.

However, it wasn't too late to be here now. Seeing that there were only a few hundred survival points left for the upgrade requirement, Dong Tianyu headed to the container storage yard.

In the open storage yard, the containers transported by ships were stacked neatly. Looking at these containers, Dong Tianyu once thought of using them as temporary rooms.

After the cataclysm, however, the fluctuating weather between harsh winter and flooding, followed by scorching heat, made living in such converted rooms impossible.

But coming here still satisfied the fantasies Dong Tianyu had while watching reality shows.

Looking at the seal on the outside of the container, Dong Tianyu pulled out his hereditary universal lock-picking device from the Shadow Space and just gave it a wave.

With a "click" sound.

The seal, which had been frozen due to the harsh cold, was shattered instantly under the attack of the external force.

He casually wanted to strip off the fragments remaining in the lock hole, but to his surprise, he inadvertently ripped the lock hole from the rest of the box with a slight effort.

Dong Tianyu excitedly opened his first mystery box of the day, revealing neatly packaged goods inside.

Seeing this, Dong Tianyu was even more intrigued. Although he had no idea what was in the box, the packaging itself hinted that the contents should be quite valuable.

The universal lock-picking device was out again. With just a stab, it opened a hole in the wooden box. Regardless of what was inside, Dong Tianyu pried the box open with force.

After tearing away the buffering foam inside, Dong Tianyu saw the items in the box.

He didn't know what purpose the device inside served, but judging from its packaging, it should have been quite valuable. However, it had likely been destroyed by the electromagnetic pulse.

Exiting the container and closing the door casually, he looked at the stacked containers. Without caring about what was inside, he collected the whole vertical column of containers into his cave mansion for decomposition.

After prying open several containers, Dong Tianyu started to feel a little bored. Though the task wasn't tiring, it was quite troublesome to open boxes one by one.

If he continues opening the boxes this way, it will take at least a week to clear the entire warehouse, and this is only for the containers on the ground floor.

Caught in this dilemma, Dong Tianyu suddenly thought about giving up on opening the mystery boxes. Although he was keen to discover surprise finds, wasting so much time didn't seem to be worth it.

Just as he was contemplating the pros and cons, Dong Tianyu absentmindedly collected a vertical row of containers into the cave mansion, subconsciously choosing to only absorb the steel of the containers and not the contents.

The cave mansion perfectly executed his command. But without the containers to hold them, the neatly stacked goods instantly collapsed and scattered on the ground.

Seeing the scattered goods in the cave mansion, Dong Tianyu didn't feel irritated. Instead, he felt quite relaxed.

With a shift of his thoughts, the items that were previously scattered all over the place were instantly absorbed by the cave mansion. The space he had designated for decomposition and absorption was once again clean and tidy.

Seeing this, Dong Tianyu realized the functionality of the cave mansion's absorption ability was much more practical than he had previously thought. If he encountered a box that couldn't be opened in the future, he could utilize the cave mansion's absorption function to directly decompose the box, thus obtaining the contents inside intact.

Having confirmed that this method of opening boxes worked, Dong Tianyu's pace of unraveling the mystery boxes increased drastically. Rows of containers vanished in the blink of an eye.

During this unboxing process, Dong Tianyu was able to widen his horizons and made plentiful gains.

Containers, from electronic instruments to daily necessities, basically had a wide variety of things. Even the medicines in Dong Tianyu's plan were obtained from a container.

Even though the types were not complete, a box of neatly-packed daily medicinal supplies could basically meet the demands of common diseases.

From medical supplies like alcohol, iodine, cotton swabs, to everyday medicines like cold medicine, painkillers, glucose, every box didn't have a large quantity, but the kinds were very complete.

Moreover, what Dong Tianyu didn't expect, the most abundant items in the containers were not various machines or devices, but various food ingredients.

From fresh food to snacks, the types of food inside were incredibly abundant.

Seeing these items, Dong Tianyu did not hesitate to keep them in the Shadow Space.

But to his surprise, even though he had stuffed the Shadow Space full of food, he had only taken containers equal to half of the storage area.

Looking at the countless containers in front of him, Dong Tianyu felt somewhat reluctant. This time, he had obtained so much, and the quality was high, yet his Shadow Space could not store them all, which was indeed a pity.

However, seeing that there were only 300 survival points left for the upgrade of the cave mansion, Dong Tianyu knew it was time to leave.

Given his previous experience, Dong Tianyu knew that only by decomposing and absorbing ordinary items, the cave mansion upgrade would always require a certain number of survival points.

These survival points required for the upgrade should be a substitute for the energy items needed for the upgrade. Such things do not exist in the outside world, at least not within Dong Tianyu's circle of knowledge.

If the cave mansion upgrade didn't require its master to be inside, Dong Tianyu wouldn't want to go back. After the upgrade was completed and he had enough space, he would be able to take all the remaining containers away.

Unfortunately, Dong Tianyu has to be in the cave mansion when it is upgrading. Therefore, Dong Tianyu could only temporarily drive back.
