In the blink of an eye, half a month passed, and the joint army of Lokeshi and Ense landed on the Eastern Plateau of the Lokeshi Empire, launching a surprise attack on the mysterious half-plane, breaking the Lokeshi Empire's record for clearing half-planes in one fell swoop.

This is historically known as the East Mosanglak Canyon Campaign.

The people on the borders of the Lokeshi Empire, the neighboring eastern Shacha Kingdom, and the Northeast's Secluded Forest Sea experienced an apocalyptic scene.

The people here recall it with a lingering fear.

Just how dangerous was the situation at that time?

If one were to describe this surprise attack in a single sentence, it would be "extremely fast in speed, immensely powerful in explosiveness and hugely destructive."

According to post-analysis by top adventurers in the surrounding civilian area, from the moment the two countries began formulating strategies, the East Mosanglak Canyon Campaign, in terms of pathway planning, had essentially locked onto the half-plane's location in the East Mosanglak Canyon with little suspense.

In terms of intensity, at first, the march of the two countries was not much different from everyday patrols; it was quite ordinary, and many people didn't even notice Ense had blended into Lokeshi's army.

However, as the joint army drew closer to the East Mosanglak Canyon, their offensive totally exploded, and the movement speed within the landing zone jumped five levels within 24 hours, attacking the Eastern Plateau where the East Mosanglak Canyon was located at full speed.

Were the demons in the half-plane panicked at this time?

A little panicked, but not too much.

The human body has its limits.

An all-out attack necessitates consideration of the overall physical stamina of the entire legion.

Moreover, considering the East Mosanglak Canyon is situated on the Eastern Plateau of the Lokeshi Empire, the high-altitude terrain significantly impacts marching speed, inevitably weakening their offensive intensity.

Facts proved their guess right. Although they caught the demons off guard, once the joint army entered the Eastern Plateau, their marching speed began to decline continuously, eventually dropping to a jogging pace.

Many soldiers experienced mild reactions to the altitude.

Typically, at such times, the demons merely need to choose wisely, split their forces to leave, and hide in the forests, and even this elite force would find it difficult to kill them all.

But this time, the attackers were Louis's Curse Binding Legion!

That afternoon, as they entered the Eastern Plateau, a terrifying scene occurred once more.

Louis and the Sword Master converged from two different directions with demigod-speed, leaving the Lokeshi army to march alone, and the two of them reached the East Mosanglak Canyon and began the first round of bombardments.

After an extreme explosion, by half-day later, the Curse Binding Legion, which Louis had released earlier on the road, completed the encirclement of the surrounding canyon.

Demons attempting to hide in other areas were dragged out one by one and killed; the legion of undead took merely half a day to shrink the encirclement to the East Mosanglak Canyon.

That night, the peak combat intensity of the East Mosanglak Canyon Campaign erupted from above the canyon.

A fearless adventurer analyzed nearby, saying during that half-hour of peak attack frequency, after a sun appeared over the original East Mosanglak Canyon, it instantly turned into a plain.

Then in the following half-hour, under the combined attack of two demigod-combatants and the Curse Binding Legion, the magma ocean of the East Mosanglak Canyon plain kept spreading outward, transforming into the East Mozambique Lowland.

Adventurers who recorded this phenomenon from different places said this:

"The East Mosanglak Canyon Campaign made those who saw the scene of the combat center from afar feel as if standing on the ground was like being on a ship."

"Trees blown away didn't just fall; they flew in the sky all the way to areas outside the impact zone."

"Shattered pieces of the half-plane were scattered throughout the entire sky."

"We've witnessed scenes of half-plane destruction before but never seen anything like this. Since then, half-plane siege operations in the eyes of eastern adventurers were divided into two kinds: East Mosanglak Canyon Campaign and other operations."

By the next morning, the second wave of the East Mosanglak Canyon Campaign erupted across the Eastern Plateau and into the Shacha Kingdom.

With aid from the knight legion sent by the Shacha Kingdom's king, though this battle was slightly weaker than before, it maintained 70% of its peak intensity.

The winds caused by the eruption nearly bent all the windmills in the Shacha Kingdom, and large segments of the uninhabited monster forest collapsed, as if the kingdom's loggers had been summoned there.

Post-battle, adhering to the belief of not using what's free, Shacha Kingdom immediately established an East Mosanglak Canyon Campaign Memorial Forest on the ruins, attracting hordes of curious lesser adventurers eager to witness demigod power.

After a night of trekking, the remaining demons and the Abyssal Church's high-ranking members were driven to a dead end by the borders of the Secluded Forest Sea, faced with the elven encirclement.

Under the cheese of a dual-sided pinch, the combat intensity at that point still wielded half the strength of its peak period.

The long-trek Lokeshi and Ense joint army united with the elves, despite having poor relations in the past, to achieve the highest level of combat intensity the Secluded Forest Sea had seen in a millennium.

The last time there was such level of warfare was when the Lokeshi Empire pierced through the Secluded Forest Sea.

Even during the Mad King's chaos, the Secluded Forest Sea, being a less affected area, hadn't witnessed such intense warfare.

The new generation of elves, and even the majority of the elder elves, seldom encountered such war.

A single battle almost awakened the Secluded Forest Sea that witnessed 50% combat intensity firsthand.
