321: He's coming, he's back

The hundred-meter-tall defensive wall was the East Sea City Base's strongest line of defense, and also its last.

Below the city wall was a blind spot for laser weapons, which could only be cleared by machine guns from internal bunkers.

Boom!

A zombie covered in bulging veins self-destructed the moment it reached the base of the city wall, and a plume of green smoke rose, filling the air with a foul stench; just by its color, it was clear this smoke was highly poisonous.

The machine gun port of the bunker was open, and before the operator could react, the poisonous mist drifted in through the port.

“Oh my god, what the hell…”

Only a trace of the pungent, foul odor in the air entered the operator's lungs before he felt an extremely strong burning sensation throughout his entire lung.

“Report, Defense Section 2 has a zombie self-destruct, the mist is poisonous, and the operator at Section 2’s operating position has lost vital signs.”

“Report, Defense Section 3 has a large amount of poisonous mist, requesting support from the NBC decontamination team.”

“Report, Defense Section 4’s energy weapon is overheating.”

“Report…”

Bai Yan listened to the series of bad news coming from the Combat Command Center, his heart growing heavier and heavier. Once the defensive line was breached and large numbers of zombies poured into the urban area, the consequences would be catastrophic.

Bai Yan had already prepared for the worst, staring intently at the screen on the large display.

“Abandon the East Section defensive wall. The Superpower Squad will roam, and all other personnel will concentrate their forces on defending the North Section,” Bai Yan sighed and commanded.

It would still take some effort for the zombies to climb up; a hundred-meter-high wall was as tall as a thirty-story building, and its outer surface was also very smooth.

After the East Section defense was abandoned, the zombies quickly reached the wall. Some zombies' palms directly transformed into suction cups, adhering to the wall.

“Holy crap, gecko zombies?”

The defending personnel who had just evacuated took a glance and felt their scalps tingle. Other zombies used these gecko-like zombies embedded in the wall as stairs, climbing up step by step.

At this moment, the Superpower Combat Squad had swiftly arrived at the scene. Suddenly, the air on the outer layer of the wall rapidly heated up, and many zombies that had been climbing close to the top instantly fell.

With the reduction in the defensive base's firepower density, it was difficult to cover the six-hundred-kilometer wall.

After more than ten minutes, zombies began to climb onto the city wall through defensive gaps, but they were quickly cleared by the Superpower Squad. However, the base's fatigue was already evident, while the zombies seemed endless, continuously emerging.

The battle reaching this point was not due to Bai Yan's poor command, but rather the overwhelming number of zombies. Some situations were not impossible to break, but due to limited resources, even giving everything they had, it was difficult to break the deadlock.

At this moment, more than a dozen bright spots appeared on the combat room's screen. There were a large number of detectors in the rock layers surrounding the Underground City. A portion of the zombies were slowly digging towards the Underground City through the underground rock layers. As expected, there was nothing that couldn't be done, only what couldn't be imagined.

“Reporting, Commander, a large number of zombies are digging into the Underground City, estimated to break through to the upper levels of the Underground City in one hour.”

Bai Yan's expression was grim; he knew that this move by the zombies was beyond his expectations. The Underground City's defensive facilities were not fully constructed, and many areas only had laser weapons and sensing devices. If the zombies broke through from underground, it would pose a huge threat to the base.

“Ability Squad, conduct pinpoint sniping,” Bai Yan quickly ordered.

Soon, many people holding energy weapon devices appeared around the Underground City Base. This was a type of highly penetrating, directional microwave weapon that used sound waves.

During the expansion of the Underground City, the risk of zombies digging underground was considered. The penetrating power of a single microwave was limited, but when multiple weapons formed an array, it was like using multiple laser beams to illuminate a single point; this was the underground pinpoint sniping.

The microwave mentioned here is not the microwave from a household oven; the wavelength of this energy weapon is longer, capable of penetrating rock layers. Multiple weapons form a standing wave at the point where zombies are digging, directly melting the digging zombies within the rock layer from a distance.

However, there were too many zombies digging simultaneously. Although a large number of zombies were killed from a distance, some zombies still entered the outer compartments. Although they were quickly cleared, they also caused some damage.

Bai Yan's face was solemn; time was not on their side. The longer the delay, the worse the situation would become.

“Reporting, Commander, the zombie offensive has slowed down.”

Bai Yan listened to the report, looking at the real-time battle damage statistics compiled by the smart AI on the large screen in the combat room. His heart skipped a beat. Why would the zombie offensive slow down at this moment? If he were the Corpse King, he would absolutely not slow down the offensive now.

Boom!

More than a dozen mushroom clouds suddenly rose from behind the zombie horde. Lin Yao looked at the images from the front-line monitor and immediately stood up excitedly.

“He, he's back.”

Bai Yan's heart filled with joy. He glanced at Lin Yao and said, “You mean Lu Tianming is back?”

“Besides him, who else could cause such a big commotion?” Lin Yao retorted.

“That's great! Now, we don't need to conserve ammunition.”

Bai Yan was very excited and said into the combat channel, “All units attention, General Lu is back. The zombies will probably retreat. Do not conserve ammunition; give me a full counterattack.”

......

At this moment, Tian Ming was hovering outside the besieged city. Coincidentally, it was while testing his clones that he discovered traces of zombies gathering to the south. Tian Ming immediately guessed that Jiang Chen had targeted his base. He did not hesitate and immediately rushed back, just in time to encounter a large zombie horde attacking the wall he had built. Without a word, Tian Ming directly joined the battle.

Tian Ming's material manipulation radius had already reached one kilometer. What does this concept mean? Previously, when creating Nitrogen Bombs of mushroom cloud level, it was already extraordinary to produce one at a time. Now, he could produce more than ten at once.

The bombs directly blasted dozens of craters several hundred meters wide in the rear of the zombie horde, while Tian Ming's second clone directly ascended to the sky to act as a scout, illuminating the map, and his other clones precisely targeted and killed the commanding Corpse King.

As soon as Tian Ming appeared, the zombie offensive immediately slowed down. After more than ten minutes, a large number of zombies began to retreat. Bai Yan and Lin Yao, among others, immediately rushed to the front line and saw the entire zombie horde retreating.

“Should we pursue?” Bai Yan looked at Lin Yao, seeking his opinion.

Lin Yao shook his head and said, “He is behind them. These retreating zombie hordes probably won't escape.”

Before Lin Yao finished speaking, dozens of bright fireballs erupted again from the rear. The scorching high temperature could be felt even on the city wall, more than ten kilometers away.

Bai Yan looked at the rising fireballs, shaking his head with a wry smile, and said, “Old Lin, he seems to have become stronger again. Before, the bombs he detonated didn't cause such a big commotion as they do now.”
