Looking at the motionless behemoth not far away, Dong Tianyu actually felt an impulse to directly take it into the Cave. If he could dismantle this enormous being, he should be able to advance the upgrade progress of the Cave to some extent.

Now, Dong Tianyu had also figured out that what the Cave needed for an upgrade was not some specific material, but carriers containing various energies.

Under normal circumstances, although those ancient creatures do not cultivate actively and can only passively absorb the nature’s spiritual energy present in the air, the bigger the ancient creature is, the more Spirit Energy it absorbs in the same amount of time.

This is why the larger the ancient creature is, the stronger its inherent defense.

However, the behemoth not far away, even if not categorized as a gigantic ancient creature, was at the very least a top-tier species between large and gigantic ancient creatures.

For that reason, this behemoth was the largest ancient creature ever hunted by the camp on this side. If Dong Tianyu were to take it away secretly, he would definitely catch the attention of everyone in the camp. Although they might not be able to trace it back to Dong Tianyu, he did not want to invite that kind of trouble.

Just as Dong Tianyu was struggling internally, Robinson William had already returned the sniper rifle borrowed from the city wall commander, did a brief check to confirm there was no damage, bid farewell to the other party, and left the city wall with his companions.

There was another reason Dong Tianyu did not take action: not counting the behemoth killed by the sniper rifle, defending the city this time had undeniably been a heavy burden for the camp.

To not mention other things, just consider the bullets spent initially in hindering the smaller ancient creatures from approaching the wall; that wasn’t a small number. Originally, if that final fire hadn’t been set,

after the defense was over, the camp could have recollected the corpses of the dead small ancient creatures.

Actually, there were many useful parts in the small creatures’ bodies. For starters, the meat of most small ancient creatures basically suited the tastes of the majority of survivors.

Aside from the meat, the coarse hide of the small ancient creatures also had many uses: they could be made into outerwear after tanning and despite their coarseness, their breathability was strong, making the hides popular for use as furniture upholstery among the majority of survivors.

Even the inedible internal organs of the small ancient creatures, aside from a part that could be rendered for oil for industrial products, the remaining parts could be crushed and fermented, then with the addition of other items, made into an excellent agricultural feed.

If the defense battle had been lost, there would be nothing left to say about the camp, but if it had been successfully defended, the corpses of those small ancient creatures would have been enough to compensate for the Ammunition spent during the defense.

Unfortunately, the intensity of defense this time far exceeded everyone’s expectations. For safety reasons, the commander decided to create a firewall with White Phosphorus Grenades.

It was this highly flammable substance that turned the stacked corpses into fuel for the flames. The large fire consumed all the small ancient creatures killed during the defense by the survivors, turning them to ashes.

Although this big fire brought victory to the defense battle, in terms of finances, what actually went up in flames were not the corpses of the ancient creatures, but stacks of bills from the camp’s revenue.

That is also why Dong Tianyu ultimately gave up. He abandoned the idea of sneakily taking the colossal creature into the Cave.

Without that giant creature to cover the loss, one could only guess how long it would take for the camp’s finances to completely recover from the gaping hole left by the Ammunition consumed during the defense.

While Dong Tianyu was somewhat selfish, he was not an absolute self-interested individual, and so he was not the kind of person who would feel at a loss if he didn’t pick up two stones to bring home when going out.

After coming down from the wall, Dong Tianyu finally decided to abandon the idea of seeking a bargain.

Although the defense was over, there were still many issues to follow up on. After descending, Robinson William bid farewell to Dong Tianyu and left with his deputy.

Dong Tianyu went over to the east side of the camp, where Ye Liuyun was waiting with the Taylor family and Mrs. Thompson for the monster siege to end.

When they saw Dong Tianyu coming over by himself, everyone’s expression tensed up, but seeing his relaxed demeanor and no signs of panic, those with discerning eyes could tell that there should not be a big issue.

Before Ye Liuyun could ask, Mrs. Thompson hurriedly spoke, "Son, what’s the situation over there now? Did they hold off the monster attack?"

Hearing his mother’s inquiry, Dong Tianyu quickly replied, "Of course, the monster siege has ended, the danger is all gone, and everyone can stop worrying now."

Upon hearing Dong Tianyu’s response, everyone truly relaxed. Madeline quickly stepped forward to ask again, "Why did you come alone, where’s my brother?"

"Although the monster siege is over, there’s still a mess left behind. Your brother is now busy dealing with those issues."

Just as Madeline was about to ask something else, a small child who had been standing with the families suddenly stepped forward and asked Dong Tianyu, "Uncle, can you tell me what just happened?"
