Crossing the wilderness to survive, starting with a broken kitchen knife.

The mother beast's body was ignited by the flames, making crackling sounds in the rain.

Zhang Shi came to the giant cannon and looked at this new killing weapon carefully.

Ge Dalong came to Zhang Shi, stuffed a giant cannonball into his hand, and explained.

"Last night, zombie beasts suddenly attacked, and the lethality of the artillery was limited. Gong Yi and other craftsmen worked all night to develop this powerful weapon specifically for zombie beasts. It just happened to happen when you had an incident, so I used it as an emergency measure and tested its power."

Zhang Shi thought of the scene of bombarding the mother beast just now. The giant shell ignored the shell and hit its body, then exploded inside its body, causing a rain of blood all over the sky. This scene could indeed be called a powerful weapon.

"This thing is really good. Its power is comparable to that of modern weapons. Let Gong Yi produce a large batch of it. If there are zombie beasts attacking again tonight, use this thing to make them suffer."

Ge Dalong nodded and added.

"I have to remind you, this weapon is great in every way, but the manufacturing cost is quite high. Even the shells are extremely expensive, so you have to be mentally prepared."

Zhang Shi did not comment and asked back with a smile.

"Do you think I'm short of money? Besides, the main component of these shells is gunpowder. We have plenty of it. How much can we spend?"

"Excluding the cost of gunpowder, the cost of one cannonball is about two gold coins."

Zhang Shi was speechless. This price was indeed beyond his expectations, but when he thought about it carefully, it was reasonable. He could only nod his head and pretend to be indifferent.

Before one problem is solved, another one arises. Wu Qing sends a message with only five words.

"Something's happening, come back quickly!"

As the saying goes, the fewer words, the bigger the matter. Zhang Shi and Ge Dalong looked at each other, then quickly rushed back to the shelter.

The noise of the rainstorm became the only sound in the wilderness, but when he approached the shelter, Zhang Shi could still hear bursts of bustling shouting. His face darkened and he felt that something was wrong.

Zhang Shi and Ge Dalong quickened their pace. The uneasiness in their hearts was like the increasingly heavy rain, weighing heavily on their hearts.

When they entered the shelter, they found that almost everyone was gathered at the back of the fortress. Wu Qing was standing on the top floor of the fortress giving orders. Zhang Shi impatiently flashed in front of her, but before he could say anything, he was stunned by the scene in front of him.

Behind the shelter, the once solid ground was now crawling with dense, disgusting worms. Behind them, a steady stream of worms emerged from the river and slithered along the riverbank toward the shelter.

The worms, varying in size from slender silk threads to thick fingers, wriggled and interwoven into a creepy carpet. Their bodies secreted mucus, which, washed by the rain, formed slippery patches of light and emitted a nauseating stench.

"What's happening here?"

Zhang Shi's voice trembled with disbelief. He had never seen such a strange and massive swarm of creatures. These worms were most likely the culprit behind the zombie crisis. The sight of such a large number of worms gathering together was an unstoppable disaster for any living creature.

Zhang Shi frowned and searched the swarm of worms for possible clues, but he found nothing except worms.

"It's unclear, but it's definitely not a good sign. What's certain is that we're in trouble."

"These worms appeared suddenly, catching us off guard. Not only were there a large number of them, but they also seemed to have developed a certain resistance to fire. I tried to attack them with fire, but it had no effect. Furthermore, the rain was so heavy that the flames were quickly extinguished."

Zhang Shi's heart trembled upon hearing this. He quickly looked around and saw that the atmosphere in the shelter was extremely tense. People were either armed and on guard, or busy reinforcing the defenses. Everyone's face was filled with anxiety and uneasiness.

"Are there any casualties?" Zhang Shi asked.

Wu Qing shook her head, but then added: "Not yet, but if we don't find a solution soon, I'm afraid..."

"Understood," Zhang Shi interrupted her, his eyes firm. "We can't just sit there and wait for death. Lao Ge, you'll organize the manpower and continue trying to drive away these worms with fire. Wu Qing, you'll lead a group of people to inspect and repair the defenses, ensure our defenses are stable, and cooperate with Lao Ge to attack the worms with artillery."

Except for Zhao Feng, who led a group of people to garrison at the transit station, everyone in the shelter joined in the battle and had their work assigned by Zhang Shi.

Afterwards, Zhang Shi found the craftsmen and tried to see if he could use artillery or other devices to find something that could eliminate these worms on a large scale.

The three of them quickly divided up their work and threw themselves into the intense battle. Zhang Shi headed straight for the research center and ran into Gong Yi walking towards him.

"My Lord, you are back. I was just about to look for you."

Gong Yi was sweating profusely and gasping for breath when he bumped into Zhang Shi. Zhang Shi grabbed him and signaled him to speak slowly.

"Master Wu Qing previously provided some worm samples, and we've been continuously researching them. Just now, we discovered a small number of worm eggs in the rainwater. They likely multiplied in the water source, causing the infection of wild animals and leading to last night's attack."

Zhang Shi was stunned after hearing this and reached out to catch some rain water, but even when he used Dingzhen to identify it, he could not find anything unusual.

"For this purpose, we have specially tailored some insecticide bombs for worms. I have tested them and they are extremely lethal to worm tissues and can also spread within a certain range."

Zhang Shi was delighted to hear this, as he finally heard some good news. He quickly asked someone to take away the insecticide bombs and went to the top floor of the fortress to test their power.

The rain continued to fall like a curtain, but the tense atmosphere in the shelter was eased by Zhang Shi's arrival. Zhang Shi loaded an insecticide bomb with his own hands, took a deep breath, and gave the order to fire.

With the roar of the cannon, the shells pierced the rain and landed precisely in the densely populated area of ​​worms. Instantly, a strong chemical smell spread along with the explosion, and chaos began to set in among the worms. Many worms, exposed to the blast radius of the insecticide bombs, rapidly shrank, transforming into pools of black liquid.

"It works!" Wu Qing shouted excitedly, her eyes gleaming. Zhang Shi breathed a sigh of relief, but then his nerves tensed again. He found the black liquid familiar, and he began to associate it with other things.

"Gan, you can't be so weird!"

The successive firing of insecticide bombs significantly reduced the worm population, but their resistance also seemed to grow stronger. Some worms began to attempt to bypass the blast zone and head towards other parts of the shelter. Seeing this, Zhang Shi immediately adjusted his strategy, ordering the artillery team to disperse their firepower and target the worms at multiple locations.

Meanwhile, Gong Yi and his research team were urgently developing more insecticide bombs and sending them to the front lines. Wiping his sweat, he said to Zhang Shi, "My Lord, these bombs are effective, but our reserves are limited, and we can't produce them quickly. We must quickly find the source of the insect swarm and solve the problem fundamentally."
