At this moment in the Honghu Region of Hubei Province, the alien creatures' worker ant subunits were constantly breaking through the ice layer, surging up from the lakebed like a tide.

Honghu is located at the border between Hubei Province and Xiang Province, adjacent to the Yangtze River, as part of the ancient Yunmeng Marsh.

After the entire Blue Star Sea level rose, Honghu also became connected with the Yangtze River and Dongting Lake, forming a whole.

After the temperature dropped, it naturally became an ice field like Dongting Lake, and even connected with Dongting Lake.

After the alien invasion, although the military had also set up a defense line here, because it was near the city where Chen Xin was located, the troops there were well-equipped, effectively restraining the alien creatures' attacks, causing most of the alien attacks to focus over there.

The Honghu Region's offensive was relatively less intense, although there were still overwhelming numbers of alien creatures; compared to other defense lines, it was relatively easier to manage here.

After all, the alien creatures were mainly surging out from around Junshan Island, first attacking the city where Chen Xin was, and the surrounding areas required the alien creatures to travel some distance to reach them.

However, now the alien creatures had evidently dug a tunnel from the Junshan Island area to the Honghu Region, and were continuously emerging from the bottom of Honghu.

Humans had long been aware of the alien creatures' tunneling abilities, as alien creatures in the West Dongting Lake area also emerged from underground in this manner.

Previously, the alien creatures mainly appeared near Junshan Island in the Honghu Region, and none emerged from underground in this area, leading people to subconsciously overlook this possibility.

Though preparations were made, in the continuous alien attacks, everyone's energy was focused on resisting the current attacks, so there was no extra effort to prepare for potential dangers.

In fact, even with preparation, it would not have been effective.

The number of alien creatures was astonishing. Even though the Honghu Region had been relatively easy to handle before, it was only easier compared to other regions.

Although not overwhelmed, there was no spare power available.

So when the alien creatures emerged from the bottom of Honghu, the whole defense line in the Honghu Region became precarious, even tottering.

All the troops on the defense line had already stepped up, and the troops that had been rotated out to rest also regrouped and returned to the defense line.

Yet, even so, they still found it hard to withstand the alien creatures' attack at this time.

The Commander of this segment of the defense line naturally called for reinforcements immediately, but it would take time for reinforcements to arrive.

Moreover, because the alien creatures were emerging directly from under Honghu, even aerial bombings could only cut off the original offensive coming along the Yangtze River from Dongting Lake, and couldn't effectively curb the attack coming directly from beneath Honghu.

At such a time, it could only depend on the frontline soldiers to resist with their flesh and blood.

Although the rear artillery began roaring quickly, just like trench warfare in World War I and World War II, if it was a no-holds-barred human wave tactic, sufficient firepower would struggle to completely suppress the opponent's attack.

After all, in modern warfare, such tactics have long been obsolete, and no country's army would use such a method to achieve victory by sacrificing lives.

But for alien creatures, the subunits were just cannon fodder, and even if left alone, they would consume themselves, so it was better to投入战场作为炮灰.

Thus, even though a shell exploded among the alien creatures, clearing a large area, in the next instant, the area cleared by the explosion would be filled by subsequent alien creatures, as if the shelling was just an illusion.

Even though the artillery at the rear kept shelling with the momentum to break the gun barrels, and indeed greatly relieved the pressure on the front line, as more new tunnels appeared beneath Honghu, attacks on the defense line increased.

Without support, the collapse and downfall of the entire defense line would only be a matter of time.

Fortunately, upon receiving the request for support, the military immediately organized reinforcements. Under the precious time gained by the frontline soldiers in desperately resisting the alien creatures' attacks, the first batch of reinforcements finally arrived.

Seeing several large helicopters lowering altitude at the front of the position and dropping the Titans they carried, this reinforcement method truly left many people stunned.

Although the reinforcement method was exaggerated, the effect was immediate.

With the deployment of these fifty Titans, and a round of offensives coordinated with helicopters, a significant number of alien creatures at the front of the position were cleared, allowing the soldiers on this segment of the defense line to catch their breath.

Although the deployment of fifty Titans could not change the battlefield situation, the advantage they created was quickly offset by the continued waves of alien creatures, but the arrival of reinforcements still gave great morale boost to the fighting soldiers on the defense line.

Moreover, this was only the first batch of reinforcements. Although subsequent reinforcements were not arriving as quickly, they were on their way, giving the frontline soldiers and Commanders more confidence to hold the defense line.

However, these Commanders also knew that the arrival of reinforcements could control the current situation, but if the problem of alien creatures continuously emerging from under Honghu was not solved, the situation could not be changed.

After all, the Honghu Defense Line now had to face attacks from two fronts, the surface of East Dongting Lake and beneath Honghu. Air bombing could block the attack from East Dongting Lake temporarily but not permanently.

And beneath Honghu, more and more alien creatures had broken through the ice layer and emerged, as if they had already opened an underground passage to this place.

The increasing numbers of alien creatures were gradually offsetting the advantage brought by the arrival of reinforcements, allowing the battle situation to continue sliding towards an unfavorable position.

"Damn it, if only we could block the tunnels under the lake!" In the command post of the Honghu Defense Line, an officer slammed the table hard, the map in front already marked with large red arrows, the vast red making the blue defense line appear so precarious.

Every red arrow represented an attack initiated by alien creatures, every arrow represented a discovered tunnel.

Without much professional knowledge, it's clear from the map that unless these tunnels could be destroyed, the alien creatures' offensives would not cease.

But wanting to blow up tunnels was nothing short of a fantasy.

Up to this point, humans had discovered many alien underpasses, but only the tunnel Chen Xin blew up during his first encounter on Junshan Island, and a few others, at the cost of significant sacrifice, had been demolished.

Currently, humans have no good methods to destroy the alien creatures' underground tunnels.
