Hearing Dong Tianyu say this, Ye Liuyun patted his chest and said, "Don’t worry about this, your mom is like my mom, I’ll make sure she stays safe."

After hearing what Ye Liuyun said, Dong Tianyu carefully pulled him aside and whispered, "The situation at the camp doesn’t look good. Take the families towards the east gate, and if the west side can’t hold, you lead everyone to Pengcheng."

Upon hearing Dong Tianyu’s instructions, Ye Liuyun didn’t say much, as the act of sending his mother over had already made it clear that Dong Tianyu was not very optimistic about the situation at the camp.

So, Ye Liuyun just nodded silently, indicating that he understood what Dong Tianyu meant.

After ensuring his mother was settled, Dong Tianyu parted ways with Ye Liuyun and headed over to the comprehensive building. At this point, the mobilization meeting had ended, and the warriors had been assigned different tasks according to their registered cultivation levels.

Dong Tianyu did not pay attention to the other warriors leaving with the constables and went straight to Robinson William.

At that moment, Robinson William was communicating with the people at the wall via his phone. A small number of Body Tempering Realm warriors with relatively lower cultivation levels were led by patrols to help transport ammunition for the wall guards.

The remaining warriors with higher cultivation were gathered with Inner Breath Realm martial artists at the city gate, ready to step out and block the monsters should any breaches occur on the wall.

As for the warriors with even higher cultivation, they were kept as trump cards and temporarily accommodated together.

After Robinson William had finished all the arrangements and hung up the phone, he relaxed slightly and greeted Dong Tianyu, "Are you heading to the Watchtower now to rest and build strength with those Energy Realm warriors, or will you join me at the city wall?"

Upon hearing Robinson William’s query, Dong Tianyu thought for a while and finally decided to accompany Robinson William. He was not familiar with the warriors at the Watchtower, so it was better to stay with Robinson William.

"I’ll join you."

After hearing Dong Tianyu’s response, Robinson William did not hesitate and directly led him up to the city wall.

At this time, although there were many people on the wall, everyone was busy with their tasks in an orderly manner.

Each shooting position on the wall was manned by groups of three to five people, two of whom took turns firing the guns while the others were busy reloading and switching guns.

To prevent the firearms from becoming unusable due to frequent shooting, each position, if only equipped with rifles, generally had more than five guns being used in rotation.

Despite the hustle and bustle of the riflemen at the shooting positions, their targets were mostly the ’fish that slipped through the net’ after the machine gun fire.

Even though the ’tat-tat-tat’ sound of machine gun firing on the city wall hardly ceased, at this time, it wasn’t the machine gunners who inflicted the greatest damage, but the almost extinct military unit before the catastrophe: the grenadiers.

It’s hard to pinpoint when grenadiers first appeared, but they gained prominence in our military during the "Nuts" war period.

The main reason was poverty, because the early military factories couldn’t produce artillery, and most of the artillery in the army was obtained through capture.

When facing bunkers, lacking artillery, the initial strategy was to fill them with lives, sending comrades carrying explosive packs to approach desperately and then igniting them to destroy the bunkers.

However, as the war evolved, bunker defenses kept improving. By the middle stage, even at the cost of lives, it became difficult for comrades with explosive packs to get close to the bunkers.

When this situation became the norm, because one couldn’t get close in person, somebody came up with the idea of tossing explosive packs near the bunkers, similar to throwing Hand Grenades.

After numerous trials, it was found that although this method could wastefully consume some explosive packs due to inaccuracies, it not only reduced casualties but also could substitute for the effect of crude cannons.

Having tasted its benefits, many units started selecting appropriate soldiers to train their arm strength, turning them into professional grenadiers, a substitute for crude artillery.

During the resistance against the washbasin chickens, the soldiers of the Rabbit family had poor rations, but to ensure that the throwers had enough strength to toss further, their meals were even better than those of ordinary officers.

Now, unlike before, to become a thrower, one must at least possess the initial cultivation level of the Inner Breath Realm.

Not only that, the objects they threw were no longer those makeshift explosives that needed to be ignited with a fuse, but high-explosive bombs made through special craftsmanship.

Normally, to achieve long-distance flight and precise explosions, one would need a dedicated launcher, but under the current circumstances, let alone Pengcheng not having such unconventional equipment.

Even if they did, the extended range of such overused equipment might not necessarily be much farther than what an Inner Breath Realm Martial Artist could throw.

Dong Tianyu watched the throwers activate the timers on their bombs and throw them far away in their preferred ways.

Perhaps after numerous trials, these bombs did not explode upon hitting the ground but instead burst into flames about a meter above it.

These bombs were packed with all sorts of things, and Dong Tianyu used Divine Sense to observe the aftermath of the explosions.

It turned out that the bombs did not contain the special items Dong Tianyu imagined, those specifically made to increase the lethal radius.

Instead, they were filled with common items once seen everywhere, such as rusty nails, broken ceramic shards, or scrap iron pieces of unknown origin.

After observing many bombs, Dong Tianyu was surprised to find that none of the bombs contained the same items; they had all sorts of things inside, focusing mainly on using available materials on site.

Even if the bombs were filled with a mishmash of items, their exploding power was not to be underestimated. Each mid-air explosion could shatter the small ancient creatures within ten meters, and the assorted carried within could cause secondary damage to the surrounding monsters.

If nothing unexpected happened, under the effect of the bombs, the machine guns could completely fend off the attacks of the small ancient creatures.

But when the small ancient creatures could no longer get close to the city wall, incessant collapsing trees from a distance in the deep forest revealed medium-sized ancient creatures within the sight of those watching from the walls.

Upon seeing the appearance of the medium-sized ancient creatures, the faces of the survivors who were anxious to help turned bitter. They were preparing to retreat from the wall and find a chance to leave the camp.

Just then, ’Boom~Boom~Boom~’, three gunshots rang out, and the recently emerged medium-sized ancient creature was sniped and killed directly by our side.

The military didn’t want to waste bullets, but with the appearance of the medium-sized ancient creatures, the atmosphere on the wall suddenly became much more silent, and a sense of panic began to spread.

So, to boost morale, the military brought out the sniper rifles that had been dropped to them in the last airdrop.

To achieve the effect of instant kills and boost morale, the military specifically arranged three sharpshooters, just to make this newly emerged medium-sized ancient creature disappear.

Before the people on the wall could celebrate over the already fallen medium-sized ancient creature, another one appeared in their sight.

As the snipers were preparing to take down the next target, more and more medium-sized ancient creatures started appearing to the west.

For a siege involving only small ancient creatures, there was no need for sniper rifles because Ye Liuyun had learned about the prices of specialized bullets through his contacts.

But when Robinson William found out the bullet prices reported by Kyoto, he reluctantly hid the rifle away.

In theory, killing a medium-sized ancient creature should yield much more than the cost of the bullets.

But during the war, the medium-sized ancient creature that had been shot was quickly eaten by other medium-sized creatures that arrived later.
