The bomb dropped was a 100-kiloton small-yield tactical nuclear bomb, which was detonated through a missile drilled into the tunnels beneath the Honghu Region's lakebed, hence no mushroom cloud rose on site.

However, this does not imply that the power of this nuclear explosion was small; quite the opposite, as all the explosive energy was contained underground, and the harm caused by the nuclear explosion was entirely absorbed by the subterranean alien creatures.

The high temperatures from the nuclear explosion directly melted the already frozen Honghu, with large amounts of ice immediately vaporized into steam. The flames and shockwave from the explosion blasted a large crater at the original lake bed of Honghu, and the surrounding soil was scorched, turned into a glass-like material.

Nearby melted lake water poured back into the crater formed by the explosion, with massive amounts rapidly evaporating into steam. Yet, influenced by the cold air, it quickly froze again, transforming into numerous ice pellets that slammed down, and once more evaporated by the heat released from the ongoing fission reactions at the lake bottom, repeatedly cycling.

Despite this, a significant volume of lake water still surged through the original channels dug by the alien beings, along with the flames and shockwave induced by the explosion.

Under the power of the nuclear blast, the entire Honghu seemed like a pot of fish soup poured directly onto a red-hot iron pan, boiled outright.

However, this did not last long, as the nuclear explosion's shockwave pressed against the lake bed's strata, causing most of the tunnels to collapse in a very short time.

Although much of the lake water was evaporated, quite a bit still deposited at the bottom of the big crater formed by the nuclear explosion and flowed into the collapsed and partially collapsed tunnels, submerging them.

Within the entire Honghu Region, whether underground or on the lake surface, the alien creatures were annihilated under the impact of this nuclear explosion.

Those on the lake surface fell into the melted lake water, cooked directly, their flesh and bones separating, turning into rich broth, while those at the lake bottom fared no better, though those on the surface evaporated along with the fish soup, while those at the bottom were scalded, mixed with the fish soup, and flowed into the alien creatures' nests along the channels.

It is unclear whether humanity's luck was good or the alien creatures' luck was bad, but this surge caused the high-level node commanding the invasion of the Honghu Region by the alien creatures to perish, leading to the alien creatures losing control in an instant.

The battle subforms and ant-like subforms do not possess high intelligence; upon losing the command of the higher node, though they continued attacking according to prior orders, it was evident they transformed from fearless warriors into retreating, fearful beasts.

Once stripped of that fearless momentum, these alien creatures were merely a large group of beasts.

The soldiers at the front line felt this change most distinctly. Despite gradually retreating under the air force and artillery cover before the nuclear explosion, their battle against the alien creatures never ceased until the nuclear blast's light illuminated the entire Honghu, when they truly felt the alien creatures' shift and the enormous combat power difference it brought.

For now, only the frontline soldiers noticed this change, with impact limited to Honghu Region; alien creatures in other areas still maintained a robust offensive, unless a nuclear bomb were deployed there to hope for a similar effect.

After deploying a tactical nuclear bomb, the military and the upper echelon had no more reservations, and considering the entire defense line's adjustment, the military utilized tactical nuclear bombs similarly in other areas detected with alien activity and invasion.

But these tactical nuclear bombs were not large in yield, unlike Honghu's 100-kiloton; most were smaller tactical nuclear bombs with only several thousand tons of yield, merely intended to destroy alien underground tunnels.

Nevertheless, at the moment the nuclear explosion occurred, the alien invasion seemed to experience a short-term pause, like they had been hit by an EMP bomb, as if their high-level command node had crashed.

But unlike Honghu Region's direct loss of command, the influence time on subforms in other regions was very short, and they quickly resumed their attack pace.

At this time, the military had not yet detected the opportunity and impact this change might bring, still busy adjusting the defense lines.

The originally encircling defense lines were pulled back in regions already penetrated and bypassed, forming protrusions, while a large part of the defense line in non-breakthrough directions retreated slightly, avoiding becoming protrusions enclosed by alien creatures.

After these adjustments, defense lines in regions breached by alien creatures following underground water layers became pocket-like, and if viewed from a map, the alien infiltration attacks seemed to probe into pockets, surrounded on three sides.

This is precisely the military's intent!

Since they couldn't be stopped, let them in to fight, using local superiority to form a siege, trapping and striking these alien creatures that broke through the original defense lines! 𝕗𝐫𝚎𝗲𝘄𝐞𝕓𝐧𝕠𝘃𝕖𝐥.𝐜𝚘𝚖

The strategic shift also brought new advantages to the war situation, and the deployment of tactical nuclear bombs similarly allowed humanity to regain ground on the battlefield.

Using such tactics, humanity did not suffer massive losses after retreating the defense lines.

Although alien activity traces have extended around many cities, relying on tactical nuclear bombs and local encircling tactics advantages, humanity still held the new defense lines, blocking alien creatures within.

Yet, given the overall adjustment of Dongting Lake Area's defense line, in regions not originally the alien's main attack direction, there were still some defense lines breached by aliens concentrating forces short-term.

Luckily, the defending forces fought desperately to reclaim the defense lines, preventing the situation from spiraling out of control.
