Despite having conducted a thorough search of the entire castle area, the Shapeshifting Demon was still nowhere to be found.
Gao Feng and Yang Zhiwen could only instruct the soldiers guarding the castle to heighten their vigilance and organize the other personnel within the castle.
The remaining Commoners were divided into several small groups, subsequently supervised by each other to ensure that no one was secretly replaced by a Shapeshifting Demon.
Over the next two days, Huaguo conducted multiple personnel and equipment Support missions into the Otherworld via the Space Gate.
Although the duration the Space Gate remained open was limited, Huaguo had already made extensive preparations.
To transport materials and personnel to the Space Gate at the fastest possible speed, the Huaguo military urgently constructed a flat road using Quick-drying Cement.
Even though the size of the Space Gate restricted the types of vehicles that could pass through, the Huaguo military spared no expense to deliver supplies to the Otherworld.
To transport materials as quickly as possible, the Huaguo military redeployed the tow vehicles used for pulling Fighter Jets from the Aircraft Carriers to the Space Gate area, utilizing them to tow materials.
The aircraft tow vehicles were small enough, highly precise, and capable of towing extremely heavy loads.
The military would first load a large quantity of materials onto a wheeled Flatbed Cart, strictly sized for the Space Gate, and then the Aircraft Carrier tow vehicle would safely tow the fully loaded Flatbed Cart through the Space Gate.
Because the Aircraft Carrier tow vehicles possessed high technical standards, allowing distance control down to the millimeter level, and despite their small size, they could tow objects weighing tens of tons or even more.
This meant that each Aircraft Carrier tow vehicle could transport dozens of tons of materials to the other side of the Space Gate in a single trip.
Of course, Aircraft Carrier tow vehicles were prohibitively expensive and could only be deployed in small numbers at the Space Gate; most of the time, All-Terrain Vehicles directly hauled the material-laden Flatbed Carts through the Space Gate.
As the Huaguo military became increasingly well-prepared, even if the Space Gate only remained open for five minutes, a massive amount of materials and equipment could still be delivered to Yang Zhiwen's Otherworld during that time.
Over the following two days, the Huaguo military conducted six Material Airdrops for Yang Zhiwen and his forces, resulting in over 800 tons of supplies and 400 combat personnel arriving in the Otherworld.
By this point, the Military Strength Huaguo had deployed to the Otherworld reached 700 personnel.
Even more significant than the personnel deployment was the delivery of various Heavy Weapons, which greatly enhanced the firepower of the 700 personnel currently fighting in the Otherworld.
The number of All-Terrain Vehicles had increased to over 200, ensuring that the entire force could achieve mechanization.
Furthermore, the quantity of Mortars, 107mm Rocket Launchers, and 12.7mm Heavy Machine Guns increased substantially.
In addition, over ten thousand various Landmines were also transported to the Otherworld.
Coupled with urgently transported supplies like Barbed Wire, the Huaguo Army fighting in the Otherworld was able to break free from the confines of the castle and construct a broader defensive line on the perimeter to repel the Demon Race's likely next wave of attacks.
And as more equipment and supplies arrived, the castle's security also began to improve steadily.
...
Nord City.
Large numbers of the Demon Race were currently attacking Nord City.
The human army inside Nord City relied on the city's fortifications to resist desperately against the surging Demon Race forces below the walls.
When the Demon Race was still 300 meters away from the city wall, the Trebuchets and large Ballistas positioned atop Nord City began to exert their power.
Stones and massive bolts flew out from below the city walls, landing amidst the clusters of the Demon Race.
The stones launched by Nord City's Trebuchets were about the size of a basketball, generally spherical, and would often bounce several times upon impact if the ground was hard.
In the face of the stones projected by the Trebuchets, many members of the Demon Race were directly smashed, resulting in burst brains or severed limbs.
However, the hit rate of the Trebuchets depended entirely on skill and luck, constituting random attacks, and since the Demon Race's charging formation was not very dense, the damage caused by the Trebuchets was often not very high.
As long as the charging members of the Demon Race weren't extremely unlucky, they generally didn't need to worry about being struck by the stones.
Conversely, the charging Demon Race were more concerned about the bolts fired by the large Ballistas.
The bolts fired by these large Ballistas possessed formidable power; even the Two-Horned Demon, a member of the Demon Race with astonishing defense, found it difficult to withstand the bolts fired by the large Ballistas.
The large Ballistas on the city walls generally targeted the larger members of the Demon Race, as larger size often correlated with stronger Combat Power.
A Demon Race member with high Combat Power might not necessarily be large, but a large Demon Race member certainly possessed strong Combat Power.
Furthermore, larger members of the Demon Race presented bigger targets on the battlefield, naturally making them priority targets.
However, although Nord City's large Ballistas were astonishingly powerful and capable of inflicting fatal damage on the vast majority of the attacking Demon Race, the problem was that the firing interval for each Ballista attack was too long.
After completing one shot, the Ballistas used by Nord City required at least nearly a minute to reload.
During this time, it was enough for the Demon Race to cover the 300-meter distance and reach the city walls.
Therefore, the large Ballistas only got one or two chances to attack.
And when the Demon Race closed within 100 meters of the walls, the true main firepower bombardment from the city walls descended.
"Fire arrows!"
A dense rain of arrows shot down from the walls of Nord City, felling a large number of the Demon Race charging toward the fortifications.
However, these arrows only had a limited effect on the Cannon Fodder units among the Demon Race; the powerful Demon Race troop types that determined victory did not suffer significant casualties from these arrows.
For instance, the Two-Horned Demon could even form a line, creating a natural Barrier to shield other more vulnerable members of the Demon Race as they advanced toward the walls.
Although the defensively strong members of the Demon Race, represented by the Two-Horned Demon, provided shelter for the more fragile Demon Race, the human Guards on the city walls continued to fire arrows.
But the Demon Race also had means of counterattack; as the distance between the two sides narrowed to a hundred meters, a large number of six-legged creatures resembling Lizards suddenly appeared at the forefront among the Demon Race.
The main characteristics of these Demon Race members were a long, pointed mouth and a tail tipped with a sharp spike.
These Demon Race members opened their mouths and suddenly shot out a Bone Spike.
"Watch out for the Bone-Piercing Demon!"
The Bone-Piercing Demon is a low-tier unit of the Demon Race, but it is a rare ranged attacker among the low-tier demons.
Its attack methods include both ranged and melee capabilities.
The ranged attack involves shooting sharp Bone Spikes from its mouth, while the melee attack relies on its sharp tail spike.
The Bone Spikes fired by the Bone-Piercing Demon have extremely high accuracy, and because the Bone Spikes are relatively thick and short, survival is nearly impossible if one is hit in the chest area.
Moreover, the range of the Bone Spikes fired by the Bone-Piercing Demon can exceed 150 meters.
At this moment, a large number of Bone-Piercing Demons within a hundred meters of the city walls fired Bone Spikes toward the fortifications, achieving extremely high accuracy, and numerous exposed human Guards were instantly and easily struck by the Bone Spikes.
Most of the Armor worn by the human Guards failed to offer them any protection.
