As soon as Li Yu finished speaking, everyone's eyes in the eting room turned to Zhong Chuchu.
Under the gaze of so many people, Zhong Chuchu inexplicably felt a bit nervous, after all, through her understanding over the past few days, none of these individuals were simple characters.
Adjusting her emotions, Zhong Chuchu seed to recall so unpleasant mories, and said sowhat sadly:
"Actually, the Oil City has been breached several tis by Zombie Tides before, but there were people who turned the tide, and then forcibly killed the zombies and supported it.
Originally, the number of people in Oil City was not just these, there were more people, and they all died, including...."
Zhong Chuchu recalled last year, when her boyfriend died in that rainy Zombie Tide.
Then, Zhong Chuchu continued: "Our thod is very simple, we buried so self-made oil bombs outside the walls, and used the oil inside the city. When the zombies arrived, we would keep pouring oil to burn those zombies to death."
After thinking for a while, Li Yu said: "The oil trap outside, was that made by you guys too?"
"Yes, but it seems the effect is not particularly good. Once a terrifying number of Zombie Tides occur, that trap quickly gets filled and flattened by the zombies."
Zhong Chuchu replied.
"Hmm, next, everyone think about whether there are better ways to improve the defense of Oil City on the current basis."
Li Yu surveyed everyone, and slowly spoke.
Everyone was silent for a while.
Yang Tianlong suddenly spoke: "Why not make the oil trap bigger, so it can accommodate more zombies?"
Nearby, Dapao nodded and said: "Yeah, dig a few big pits."
Zhong Chuchu awkwardly said: "That oil trap was originally ant to be bigger and deeper, but the zombies fell down, and after the oil burned, they rotted into piles of black viscous matter, so even stuck and solidified on top."
"The number of zombies in the tide was a lot, and for so long, that oil trap couldn't be cleaned up. The corpses inside burned and then fused with the oil and soil, hardening."
Zhong Chuchu's words surprised everyone.
They had all seen those pits, and inside, it was all black.
"Originally, how deep did you dig?" Li Yu asked.
Zhong Chuchu replied: "Originally, it was five or six ters deep."
Gasp!
Everyone took a sharp breath, they went to see the trap and it was less than a ter deep, aning there were at least four or five ters of zombie corpses buried inside.
How many zombies had died there.
Everyone realized that the Zombie Tide here was not as simple as they thought.
Li Yu then said to everyone: "Any more opinions, feel free to speak up."
Everyone frowned and thought hard.
Regarding this issue, Ju Tianrui and the others were very concerned.
After all, in the future, when they take turns on duty, they will co here too, and they will have to face this problem if a Zombie Tide breaks out.
After a while, so people expressed their opinions.
So people thought about creating so barriers, but others argued that this thod wouldn't be very effective, as barriers can only hold off a small number of zombies.
Actually, with the current wall, facing a small number of zombies is no problem.
The key is when there's a massive Zombie Tide, facing the pile-up of zombies, barriers can be overwheld.
So said they could choose a location with a good geographical advantage, preferably between cliffs or tall buildings, to attract zombies there and let them fall to their deaths.
Quickly, there were rebuttals.
Questions were raised, mainly it was a plain here, with no cliffs around.
It was more of a suburban area here, with no tall buildings.
More crucially, what to attract with?
In the rain, while drones with speakers could be used, but previously they tried it at the Big Camphor Tree Base, the range was only effective up to five kiloters, and once the drones reached their flight limit and returned, the zombies would still co back.
Unless using Zombie Attraction Potion, but Li Yu wouldn't easily let others use it, this thing could only be in his hands.
But he couldn't stay in Oil City all the ti.
If soone had ill intentions and brought the Zombie Attraction Potion into the Big Camphor Tree Base and shattered it, the consequences would be severe.
Furthermore, with so many zombies, using a speaker could only attract a part, a drop in the ocean.
The atmosphere suddenly turned heavy.
Ant suddenly spoke: "Since there's a lot of oil here, let's take advantage of this strength."
"What do you an?" Li Yu heard this suggestion, and was delighted.
Finally, soone had grasped the key point.
The Oil City managed to hold on until now precisely because of its endless supply of oil, right?
Maximizing the advantage of oil would be good.
The thod Li Yu had in mind was to utilize the advantage of oil and form an oil barrier.
Ant looked at Li Yu and said: "I do think the original oil trap was a good idea, but I think the trap wasn't dug too shallow, rather it was dug too shallow."
Upon hearing this, everyone looked at him with so doubt.
Ant continued: "The reason the oil trap got filled up is that after zombies die, they attract more zombies to jump in and feast.
In this way, the trench is only this wide. Once there is a massive Zombie Tide, it won't take long to fill up, even if it's still burning below. But it still can't stop tens of thousands of Zombies.
So I think, since the current Zombies have a characteristic, which is that they will eat their dead companions, let's free up so space for them. Instead of digging a small hole, let's dig a 20-ter-wide trench centered on the Oil City."
Third Uncle frowned and said, "Isn't this workload too large? This doesn't seem simpler than rebuilding a wall."
Li Yu heard this and already knew Ant's idea was similar to his.
So he smiled and said, "What if we only dig a ten-centiter trench?"
"Then we can use the difference in height to create so pipe openings from under the Original Oil City wall, which are usually closed, but before the Zombie Tide arrives, we can flood it like opening a gate."
As Li Yu spoke, everyone looked at him with shocked expressions.
Ant looked at him with appreciation, feeling a sense of camaraderie.
Ant picked up Li Yu's idea and said, "Actually, when there was a heavy rain before, using oil spraying consud quite a lot of oil and was labor-intensive, requiring continuous spraying. It greatly exhausts physical energy."
"We can imagine that once this 20-ter area is ignited, it becos a sea of fire. Any Zombie stepping into this area can't escape. It can't fly, and before they walk twenty ters on the oil, they're probably burnt to death.
And these burnt Zombies would attract those following behind to stop and eat those who ca later.
Most importantly, the space is large enough, and with dispersion, enough Zombies can burn to death in the sea of fire."
Third Uncle lightly patted the table and smiled, saying: "This thod is good, and if it's just digging a ten-centiter trench, it's very simple. Just using a digger to shovel down, one shovel can easily dig fifteen to twenty centiters."
Everyone listened to this suggestion and expressed their admiration.
Zhong Chuchu, hearing what they said, bright-eyed, said:
"In this way, not only would we not waste oil, but we could maximize the effectiveness of the oil. Generally, Zombie Tides occur during rain, utilizing the terrain's high and low differences. As water flows everywhere, it can also carry oil into lower areas.
After all, oil can ignite even when it ets water."
Li Yu nodded.
Nowadays, the Original Oil City doesn't actually have much height difference outside the walls.
But if we artificially create so height differences, as long as the Original Oil City is higher than outside, it doesn't need to be much, just fifteen to twenty centiters. Once the oil is channeled into those relatively lower areas, they could beco Zombie burning zones.
Li Yu glanced at everyone and said to the group, "What do you all think of this thod?"
Everyone raised their hands, indicating they thought it was a good idea.
Although it hadn't been tested practically, the cost is low anyway, and the trench we need to dig is very shallow, just fifteen centiters is easy.
Moreover, they have machines and equipnt, so operation will be quick, almost as easy as using a tractor to plow fields.
With so many people, we could probably get this done in a few days.
Seeing everyone raise their hands, Li Yu slowly said, "Good, then it's decided. Today is not enough ti, we'll start tomorrow."
"Alright."
"Alright."
......
Everyone nodded in agreent.
Li Yu was about to stand up when Li Tie beside him suddenly said, "Why not also lay a layer of cent? Anyway, we got a lot from that Motorcycle Gang lair, and it won't all be used up. Laying a layer of cent feels more sturdy."
Li Yu sat back and nodded, "Sure, your suggestion is good, as long as there's enough cent."
Then, seeing everyone had nothing more to say, Li Yu announced the eting adjourned.
After the eting, the ti was already past five.
The cooperative personnel originally repairing the walls were lined up to receive today's food.
They were sweaty, but when they received the food, their faces were filled with smiles.
Li Yu, seeing this scene, felt quite emotional.
This, in ancient tis, would be considered using work instead of relief.
...
Night fell.
In the canteen, Zhong Chuchu shared the day's news with everyone. The people from the Original Oil City were very happy upon hearing it.
At least, it sounds quite useful.
.....
Hundreds of kiloters away.
In Huangshi.
A Taoist climbed up a big tree. Using the moonlight, he took out a Compass from his chest.
Mumbling to himself: "Northwest direction, looks like the direction is right."
Then he put the Compass back in his chest and took out a piece of palm core from his chest.
He put it in his mouth and chewed slowly.
The taste of palm core isn't good, but at least it supplents his carbohydrates.
