Chapter 729: Chapter 289: The Safe in the Laboratory [10,000 Words]_4

But to be safe, he still needed to throw more money into the fireplace.

Mu Rufeng entered the room and also pulled the eight monsters inside, then used two blasts of Ghost Power to shut the door.

ROAR~~!

A loud booming noise came from outside the Ancient Castle, causing it to tremble even more violently.

Mu Rufeng remained calm.

He walked to the fireplace and took out a hundred million in soul banknotes, stuffing the furnace full, causing the flames to expand instantly and reach an extremely high temperature.

It felt like that metal pole Yalu was holding earlier would have melted immediately upon insertion.

"Alright, do whatever you need to do, go to sleep, and we start the second round of the death game after breakfast," Mu Rufeng shouted to everyone.

"That... Mr. Sen, are you sure the castle won’t be breached?"

"Breached? Haha, what do you think I just threw money into the fireplace for? To tell you the truth, I threw a hundred million soul banknotes in there."

"Even a Level 9 Ghost Emperor blasting all night wouldn’t be able to break through," Mu Rufeng stated lightly.

Upon hearing this, everyone breathed a sigh of relief.

However, someone quickly spoke up, it was Maria: "Mr. Sen, although I feel that the protective barrier can protect the Ancient Castle from threats, isn’t our castle located on the edge of a cliff?"

"What if that creature damages the ground? Could that cause the ground outside of the castle to crack and collapse down the cliff?"

Upon hearing this, Mu Rufeng’s gaze sharpened slightly: "How did you know?"

Considering the blizzard when they arrived on reindeer, they couldn’t have clearly seen the surroundings.

So this person shouldn’t possibly know that they were atop a cliff.

"The instance information mentioned it, Death Castle was built next to the cliff of Death Canyon Mountain," Maria said.

"Hmm?" Mu Rufeng looked at the other Contractors.

"Yes, our instance information mentioned it too," the other Contractors also nodded in agreement.

"I see, don’t worry. If that creature could damage it, it would have done so already during its previous attacks."

"If I’m not wrong, the ground here has also been reinforced with special powers and is extremely sturdy."

"The creatures could at most damage the surface soil layer; the deeper rock layers are untouchable," Mu Rufeng stated.

Hearing this, the Contractors all relaxed.

"Good, go rest now, tomorrow we have the second round of the death game," Mu Rufeng finished, opening a ghostly passageway, and vanished with the ten monsters.

They were about to say something but saw that Mu Rufeng had already disappeared, leaving them nothing more to say.

Everyone looked at each other, then quietly headed upstairs.

Still, some people whispered softly, discussing something they didn’t know.

Mu Rufeng first returned to the butler’s room and then, after throwing another hundred million into the fireplace, went up to the third floor.

This time, Mu Rufeng didn’t use the Universal Key but took out the large bunch of keys.

He didn’t need to try them one by one, as one key seemed to be attracted, slightly wiggling.

Mu Rufeng immediately took that key and inserted it into the lock of the laboratory.

With a click, the door was unlocked, and Mu Rufeng pushed his way in.

Mu Rufeng also dragged the ten monsters inside, dropping them off to the side.

Then, he returned to the fireplace, threw in another hundred million, and began searching for the safe Mumu Ya had mentioned.

Yet, he couldn’t find the so-called safe even after searching everywhere, not even using ghostly scrutiny layer by layer.

Mu Rufeng furrowed his brows; since Mumu Ya’s task was to search in the laboratory, it must be here.

Unless this wasn’t the laboratory, but with all the equipment and experiment logs inside, how could it not be?

Then there was another possibility, that the safe could only be found by Mumu Ya?

Mu Rufeng was just about to go find Mumu Ya.

But suddenly he stopped and, as a butler, issued an additional task directly to Mumu Ya.

Yes, as an NPC of the instance, he had the right to assign tasks to players.

Yet after waiting several minutes, Mu Rufeng didn’t see anyone come and frowned.

However, he soon realized something: he was now the master of the Ancient Castle, so he could access the third floor.

But Mumu Ya was just a game player and didn’t have access to the third floor.

Mu Rufeng immediately left the laboratory to the staircase.

Sure enough, he saw Mumu Ya on the stairs below, looking conflicted and anxious.

"Come up," Mu Rufeng called out to Mumu Ya.

Mumu Ya hesitated momentarily, but then understanding dawned and his face lit up.

And a prompt immediately sounded in his mind.

[With Dorgula Sen’s permission, you have been granted access to the third floor.]

Mumu Ya immediately ascended to the third floor.

Yet despite being on the third floor, the surroundings were filled with dark mist, with a visibility of barely over a meter.

If it weren’t for Mu Rufeng standing in front, he probably wouldn’t have dared to go up.

"Mr. Sen," Mumu Ya greeted.

"Hmm," Mu Rufeng nodded as a response.

Then, following Mu Rufeng’s lead, they entered the large door of the laboratory.
