I Inherited 5,000 Years of Family Property-Chapter 1629 - 1633: You Should Be Grateful There Are 4 of You

"Wait!" Zhang Menglong suddenly called out to the four Demon Lords who were about to leave, "The wager just now was, if you lose, not only do you have to return to the Demon Clan world forever and never invade again, but you also have to fulfill one condition for us, you haven't forgotten that, right?"

The expressions on the faces of the four Demon Lords flickered; they were somewhat confident when they said it, but they didn't expect to lose, and lose so thoroughly. Now it's time for them to fulfill their promise.

"What do you want us to do?" The Demon Lords weren't the kind to break their word, but the thing was, if Zhang Menglong really wanted to force them to do something, they'd need the ability and capital to resist.

"Nothing much, just want to ask you to help guard this Demon Realm gate for a while." Zhang Menglong said with a playful smile.

"We've already promised you that we won't step foot in the human world no matter what. Are you doubting us?" The Demon Lords suddenly became displeased.

"I'm certainly happy to believe you," Zhang Menglong explained, "However, I feel that the competition within your Demon Clan is quite fierce now; who knows when you might get knocked off, and then the new Demon Lord brings the Demon Clan back, wouldn't that be troublesome for me?"

"But if the four of you are here, unless all four of you are overthrown together, there shouldn't be any problems."

"How long do you want us to guard here?" The Demon Lords asked.

"Not too long, just guard for ten billion years for now!" Zhang Menglong said casually.

"Impossible! We don't have that much time to waste here!"

"Then I have no choice," Zhang Menglong shrugged, "Maybe I'll just have to take you four out directly, and support four new Demon Lords for the position. I think there are still plenty among them willing to do this for me!"

"Anyone want to be a Demon Lord?" Zhang Menglong shouted.

Sure enough, as soon as Zhang Menglong said it, many Demon Emperors showed eager expressions.

To personally defeat the Demon Lords, that's probably something they might never get a chance at in this lifetime, but if Zhang Menglong is willing to take out the current Demon Lords, they wouldn't mind giving it a try.

Even though ten billion years is long, if it means getting a Demon Lord position, it doesn't seem like such a waste.

But none of them dared to show it on their face, after all, if they showed too obviously, the four Demon Lords might directly take them out on the spot.

The four Demon Lords looked at each other, seeming somewhat hesitant.

"Puppet, help me take them out!" Zhang Menglong summoned the pink fat guy again, "I'm not very patient, giving you ten seconds to think!"

"We're willing, we're willing!"

Not even ten seconds had passed before the four Demon Lords hurriedly spoke.

Everyone had just seen how powerful that pink fat guy was; just one Energy Sphere, in their current weak state, it's estimated that none of them besides the South Demon Lord would survive.

Ten billion years then, whatever, they are immortal Demon Realm supremes anyway, at most working for Zhang Menglong for ten billion years, it's better than losing their lives, right?

"Drake, find some people to supervise, rotate shifts, don't let them leave this range by ten kilometers. If they leave, come find me!"

"Alright!" With so many people in the Human Alliance, it wasn't hard to take turns guarding these Demon Lords; this was mainly just going through the motions anyway — if they really wanted to rebel, no amount of supervision would help.

As all the Demon Clan disappeared behind that door, the door leading to the Demon Realm finally closed slowly.

The four Demon Lords sighed as they watched the gradually disappearing door.

"Don't sigh!" Zhang Menglong stepped forward, "You should be glad there just happen to be ten of you."

"Human, what do you mean by that?"

"If you do something enjoyable, ten billion years could pass in the blink of an eye!"

"Enjoyable things?" To the four Demon Lords, their daily life used to be year after year, day after day of cultivation; as for happiness? It was only when they defeated the old Demon Lords and became new Demon Lords that they experienced brief happiness.

After that, they were always worried about being replaced, how to seize more resources and expand their territory, how to bring the human domain under their control.

"Heh heh, there are plenty of enjoyable things! First, let me introduce you to our national treasure!" Zhang Menglong took out a table, four chairs, and a set of Mahjong tiles, eagerly teaching the four Demon Lords how to play Mahjong.

...

"My heavens, this Mahjong thing is so interesting! Pung!"

"North Demon Lord, you dare eat my tile?"

"Got it! Haha!"

...

"Next, shall we play a tense and exciting game of Flying Chess?"

"Interested in learning about Script Murder?"

"Damn, should've kept a few more Demon Emperors with us, we're short for this Script Murder!"

"What's the point of being Demon Lords? It's boring, being human seems fine."

"Maybe we shouldn't go back after all?"

...

After playing around with these Demon Lords for some time, they almost learned to entertain themselves, so Zhang Menglong left the Kevila Volcano area.

With the threat of the Demon Clan gone, humans returned to their previous way of life. Although Drake's status as the Human Emperor was nominal, due to Zhang Menglong and his contributions to humanity, most humans still respected him fairly well.

Zhang Menglong returned to Earth's new territory to live peacefully for a while longer.

However, a peaceful life never lasts; after only three years, a Dark Magician came and found him.

Zhang Menglong remembered that this person seemed to be one of Drake's subordinates.

"What's up?" Zhang Menglong asked, "Did something happen to Drake?"

"Mr. Zhang, the Human Emperor is fine, but there's trouble with the gate to the Divine Realm."

"Hmm?" Zhang Menglong frowned, "The Demon Clan's world issues were just resolved, now there's trouble with the God Race's world, intentionally making it hard for me to live in peace, right?"

"What's going on? Are the God Race also invading the human world?"

"Not exactly," the Dark Magician said, "Since those Demon Clan went back last time, a silvery white gate appeared in the sky over the Southwest horizon region."

"Moreover, the door in the Kevila Mountain region, leading to the Demon Clan, has also reappeared."

"What? Are those Demon Clan suicidal, daring to return?" Zhang Menglong became somewhat angry.

"No, we've consulted the Demon Lords, and they said it wasn't their doing. They suspect the God Race triggered something, causing a peculiar resonance between the two gates."

"The consequences?" Zhang Menglong asked.

"It's not clear yet," the Dark Magician said, "But human scientific pioneers have discovered a special gravitational singularity on the connection line between the two gates; the singularity's gravity is continuously increasing."

"They boldly speculate that if this gravity becomes strong enough, our human world could directly be crushed."
