The blood moon gradually turned into a waning moon, and the scarlet moonlight faded.

The number of beasts in the horde was decreasing at a visibly noticeable speed.

At the Su Family’s Old Mansion, Su Can watched the mechanisms in the corridor fiercely slaughtering batches of Shadow Beasts and couldn’t help but exclaim:

"Linzi’s design for this courtyard is really useful; without any leaders interrupting the operations of the mechanisms, I don’t even need to step in."

Su Qi nodded:

"Indeed, with enough mechanisms, the Shadow Beasts can’t even get into the main yard."

The design plans Su Lin handed over to the old mansion were originally envisioned as his blueprint for a future Level 5 Safe House.

With sufficient mechanisms, compared to a Level 4 Safe House, the position of the outer courtyard gates had changed; they were moved from the east and west sides to the north of the east and west courtyards.

Additionally, a corridor was added to the south.

In this way, the beast horde needed to enter the two inner courtyards from the northern gate, then enter the southern corridor, finally allowing them to reach the main yard and attack the Safe House located to the north.

It’s akin to taking a loop around.

Wu Shiheng, who had become a tenant of the Su Family’s Old Mansion, exclaimed in shock:

"Young Master Su Li truly has an endless stream of brilliant ideas; how much time has passed, and he’s already improved the new Safe House structure! I wouldn’t be surprised if this new courtyard format quickly becomes popular at the Upper-level Camp soon!"

Su Qi said helplessly:

"I just hope he can keep a low profile for now; otherwise, before even entering Zhoushan Town, he might be resented by some people."

Although the courtyard format is useful, it doesn’t actually contain much technical content. The only thing missing was a bit of inspiration.

Perhaps that bit of inspiration was decisive.

But not everyone will necessarily think this way.

"The blood moon has disappeared!"

Just as Su Qi was pondering about the future, the other tenants let out a cheer. Looking up, they saw the crescent moon vanish.

Dark clouds once again covered the sky.

The scarlet moonlight disappeared.

The mechanisms in the courtyard also stopped operating simultaneously.

Shadow Beasts, in their clawing gestures, silently turned into a dispersing black mist.

The Night of Survival... was over.

"The Night of Survival is over!"

"Hahaha! Unprecedented ease!!"

"We survived!!"

"Boohoo..."

The village echoed simultaneously with cheers that soared to the skies; the massive sound wave seemed to shake the entire Wuyin Village, and no amount of night could block the festive atmosphere rising at this moment.

Su Lin stepped outside the courtyard, gazing at the distant spark of firelight from every household, listening to the continuous thunderous cheers. He took a deep breath in and exhaled long and heavy.

Su Tongxi walked slowly down the corridor, tears shimmering in her apricot eyes:

"Brother Kirin... it’s over."

Song Yiyi playfully leaped high, jumping onto his back, her long enchanting legs clamped tightly around Su Lin’s waist, loudly cheering in his ear:

"It’s over!!"

"Yeah. It’s over."

Su Lin felt a bit dazed, feeling that his efforts were worthwhile.

The desperation over the past month had exchanged for this night’s ease.

"If every Night of Survival from now on could be like tonight... wouldn’t that be wonderful," Su Tongxi sincerely hoped.

Su Lin paused for a moment, nodding heavily:

"Yes. It definitely will."

This month was over, but there is another month to come.

It won’t be long until they advance to Zhoushan Town; as resources increase, the difficulty of the beast horde will also increase.

One shouldn’t stagnate due to a moment’s ease.

"Let’s go collect the Shadow Cores."

Su Lin called back the Giant Beast-Hunting Bee swarm patrolling outside to help gather the scattered Shadow Cores.

The blood moon lasted for nearly an hour and a half, significantly shortening the typical beast horde duration by half.

However, the blood moon lacked wave intervals, causing the earliest killed Shadow Cores to disappear.

Only the Shadow Cores from the last half hour remained.

Su Lin and his two companions raced against time to collect... or sweep.

With no rules limiting them and the lure of Beast-Luring Incense, the number of Shadow Beasts killed by the mechanisms in the two courtyards was absurdly high!

Even with only the Shadow Cores from the last half hour left, they still covered the ground thickly!

Su Lin immediately activated Divine Speed, scooping up piles of Shadow Cores with a shovel and dumping them onto the House Title Deed.

Swish, swish, swish, he transformed into a blur, swiftly scooping up Shadow Cores, the number displayed on the pages rising at an astonishing rate.

In less than half an hour, he had scooped up all the Shadow Cores in both courtyards.

Upon seeing the number of Shadow Cores on the House Title Deed, Su Lin couldn’t help but pause:

"So many!?"

Su Tongxi and Song Yiyi gathered around to take a look, finding the number of Shadow Cores had reached an astonishing eleven thousand!

To think, they had just upgraded to a Level 4 Safe House four days ago, and each night had yielded just over ten thousand Shadow Cores.

Song Yiyi counted on her fingers, incredibly shocked and said:

"Did we just collect over seventy thousand Shadow Cores tonight?!"

"During the Night of Survival, Shadow Beasts drop Shadow Cores that are three times larger; one Shadow Core equals three regular ones," Su Tongxi was equally shocked beyond belief, "Which means we killed over twenty thousand Shadow Beasts in just half an hour!"

"Um... yep... twenty thousand beasts, half an hour, one hour thirty minutes, half hour thirty minutes, one minute sixty seconds, half hour eighteen hundred seconds, twenty thousand divided by eighteen... uh..." Song Yiyi frowned deeply, lost in thought.

Su Lin calculated swiftly, arriving at the number: 𝗳𝗿𝐞𝕖𝘄𝗲𝕓𝗻𝚘𝚟𝕖𝐥.𝚌𝕠𝕞

"Eleven per second on average."

"Hiss—!"

The two girls took a sharp breath.

Su Tongxi said in astonishment: "Our family’s mechanisms are simply too powerful!"

Song Yiyi nodded repeatedly, gazing at Su Lin with small eyes sparkling with bright stars, full of admiration as she said:

"And Brother Lin’s designed courtyard too!"

"Our family being at the forefront of the village, coupled with the Beast-Luring Incense, made the Shadow Beasts come quickly and get killed quickly. Calculating based on twenty thousand beasts in half an hour, we probably killed at least sixty thousand Shadow Beasts tonight, likely drawing a significant part of the beast horde here to be slain."

The shock on Su Tongxi’s round little face was unceasing.

Even though she knew Brother Kirin’s mechanisms were extremely powerful, she hadn’t expected that a single Safe House could kill nearly half the attacking Shadow Beasts in the village.

This slaughter efficiency is practically a savior for the entire village.

A single Safe House significantly reduces the pressure on the whole village!

"Without leaders to interfere, the mechanisms at home are indeed useful."

Even Su Lin couldn’t help nodding, amazed at the extermination efficiency with mechanisms operating at full firepower.

Yet, it was a pity that several ten thousand Shadow Cores earlier couldn’t be collected in time and were wasted.

If only there was something like an automatic loot collector from games.

Su Lin had thought about it many times before.

"To upgrade to a Level 5 Safe House requires one hundred thousand Shadow Cores, with ten thousand needed to upgrade doors and walls separately. Let’s upgrade the walls first to avoid them being pushed down by Shadow Beasts during the Night of Survival at Zhoushan Town and causing trouble."

Su Lin pondered and immediately used thought to perceive the House Title Deed, upgrading the walls.

Suddenly, the entire Safe House, including the courtyard, emitted a faint glow.

On the House Title Deed, a clear and organized script appeared:

"Wall upgrade in progress, countdown: 3 hours 59 minutes... please do not leave the Safe House area."
