The Demon Emperor was Saint Emperor

Chapter 129: Underground City

The Demon Race Underground City was a product of the Demon Race’s massive invasion of the Divine Protection Continent.

At that time, the Demon Race was at its peak, causing the Continent Alliance to cry out, almost powerless to resist.

But fortunately, it was also a period of rapid player development. Because of their activity and "Undying Body" attribute, the Demon Race never managed to completely conquer the last continent of the Miracle World.

What was originally a crushing offensive was forcibly reversed into a tug-of-war, infuriating the Demon Race’s upper echelons, who then decided on a plan to take down the entire Miracle World inch by inch.

Constructing the underground city was their method to deal with the Continent Alliance reclaiming lost territories from them repeatedly.

You can take back the fallen lands, but underneath, they’re all my Demon Race’s underground cities. Can you still sleep soundly on top, or even march across these lands to attack further?

With the underground cities, the Demon Race could ambush the Continent Alliance troops at any time and cut off their formations or retreat once they advanced.

If the underground cities weren’t cleared out, reclaiming lost grounds would be in vain and could even place them in danger.

However, clearing out the underground cities was extremely difficult for the Continent Alliance. Not only was the dark underground environment more suitable for the Demon Race’s combat, but the layered geographic environment made it hard for large armies to deploy, preventing rapid advancement and making it challenging to clear out every corner.

Only the Demon Race, with billions of clans, could construct such complex underground cities so quickly. History has even recorded an underground city 99 levels deep, which required a military force of tens of millions from the Continent Alliance and took three years to conquer.

But all of this became a thing of the past after the divine weapon descended from the heavens and wiped out the demon leaders a year ago.

In that war between gods and demons, the Demon Dragon Emperor rallied various demons and not only brought the mighty armies of the Demon Realm but also withdrew main forces from various underground cities, intending to destroy the Divine Protection Continent in one fell swoop.

Honestly, it almost succeeded, reaching all the way to the World Tree under the True God’s protection.

Unfortunately, a miracle descended from the heavens, causing the Demon Dragon Emperor’s efforts to fall through, along with a majority of the Demon Race’s foundation, though it wasn’t reduced to barely surviving, it certainly wasn’t as glorious as it once was.

After the war between gods and demons, the Demon Race’s main forces retreated and fled, driven out from the Divine Protection Continent, only halting their decline after losing half of the Divine Protection Continent.

After losing the main forces, the remaining underground cities on the Divine Protection Continent became isolated, faced with being picked off one by one.

Over the past year, the Continent Alliance dispatched troops to extinguish hundreds of underground cities, encountering little resistance. However, the work wasn’t over due to the complex underground environment and the myriad of underground cities the Demon Race constructed like stars in the sky.

Yet, the Continent Alliance didn’t consider the leftover Demon Race underground cities as a major threat. After all, they were only defended by the old, weak, and ill, at most sheltering some remnants when the Demon Race’s main forces retreated, incapable of causing a significant stir.

But Lynn recently received intelligence from the Lust Demon King that a high-level Saint Tier Great Demon had emerged in an underground city. If this information reached the Continent Alliance, it might give them a cold sweat.

To Lynn, a high-level Saint Tier Great Demon was just a larger grasshopper at level 700, but to the Continent Alliance, no longer protected by the player community, it was top-tier combat power.

"Vivian, come with me for a trip, I found an opportunity to help you level up."

Lynn didn’t take an underground city defended by a mere grasshopper too seriously. Just as well, he hadn’t found the chance to help Vivian level up, and this time, cleaning out an underground city would surely involve fighting many from the Demon Race, and the underground city’s "monster" levels were relatively low, much safer than a chaotic battlefield, making it perfect for a newbie’s takeoff.

"Just the two of us?"

Vivian pointed at herself, somewhat surprised as she asked.

Previously, they mostly went out as a family, barely having solo dating opportunities. Was Lynn planning to make it up to her with a romantic outing?

As for leveling up, it was probably just an excuse. With her being such a noob, even a True God might not be able to carry her...

"Little Youli and Little Yuna aren’t allowed to go, stay at home to keep watch. If Xiya is interested, she can join in for the fun, but there’s no need for you to act."

Clearing out an underground city wasn’t about fooling around. Since he dared to bring one wife, bringing another wasn’t an issue. However, Xiya’s level wasn’t bad, so the experience from low-level demon monsters in the underground city wouldn’t be enough for her, leaving Vivian to benefit for now.

"It’s fine for you two to go. I’ll stay at home with the kids, just don’t take too long and remember to come back for dinner."

Xiya had always been understanding, although she didn’t yet know where Lynn planned to take Vivian this time, she was willing to give them alone time. After all, compared to her, Vivian was Lynn’s legitimate lover, and she shouldn’t interfere before her own status was confirmed.

"Don’t worry, even if we don’t make it back by noon, we’ll definitely be back by evening. It doesn’t matter about food, but tonight, I want to enjoy you."

Lynn playfully flicked Xiya’s pert little nose, not forgetting their agreed benefits. Even if the river dried up today, tomorrow it still flowed, and who dislikes a little extra personal gain?

"I’ll be waiting for you at home then."

Xiya batted her eyes, her beautiful green gaze filled with smiling intent. If it weren’t for the kids being there, she might have suggested a bath, then preparing to wait for him to return.

Once everything was arranged, Lynn didn’t dawdle. He waited for Vivian to change into an easy-to-move-in outfit before heading towards the Teleportation Array with her.

The coordinates given by the Lust Demon King weren’t near Celestial Destiny City, but just outside a military fortress. It was an underground city that had been purged once and was nearly abandoned.

Unknown when, some demons began migrating there gradually, forming a bit of a scale. Even if a Great Demon hadn’t unexpectedly emerged there, Helena might still arrange for its second purge in her busy schedule.

Lynn’s trip might have even saved Helena a bit of trouble, sparing her from issuing one more order.

After warping through three arrays, then buying two horses temporarily for travel, Lynn and Vivian quickly reached their destination.

The entrance to the underground city was wide open, revealing a passage leading underground, with faint wisps of demonic qi wafting out from below, giving no appearance of danger.

Being near a military fortress, the demons in the underground city didn’t dare to roam outside, making it easily overlooked.

If it weren’t for the Lust Demon King’s tip-off, Lynn would’ve never paid attention to this place.

"Stay close to me, don’t stray a single step."

Lynn seriously instructed Vivian, as his strength was enough to protect her from any demon, provided she behaved and didn’t wander off.

Having seen countless stories of brainless female protagonists or supporting characters causing trouble, either in books or films, Lynn was understandably a bit worried.
