Global Catastrophe: I Became the World Tree-Chapter 223 - 170 Initial Battle_1

At this moment, Bai Yinghui and a host of generals had also arrived atop the North City Wall.

When they saw that the powerful insecticide failed to kill any of the mutated insects, although they had anticipated this possibility, their hearts still sank.

"How much of the second-generation powerful insecticide do we have in reserve?" Bai Yinghui couldn’t help but turn to Chief of Staff Jianyi and ask.

"The production process for the second-generation powerful insecticide is too complex, and it also requires a considerable amount of mutated plants that contain toxins as raw materials. Therefore, we’ve only been able to urgently produce around 200 pounds, which can only be used in critical areas," Jianyi sighed and replied.

"Given these mutated insects’ resistance to the insecticide, how many do you estimate that 200 pounds of the second-generation powerful insecticide can kill?" Bai Yinghui asked with furrowed brows.

"According to the deliberations at the headquarters, at most two million," Jianyi answered.

Upon hearing this, Bai Yinghui couldn’t help but exhale a silent sigh. The Chinese Academy of Sciences had long been developing the second-generation insecticide.

But because the production process was so complex, they were continuously perfecting it.

When the third Spiritual Energy Resurgence brought about a large-scale onset of Second Order Mutated Insects, the Chinese Academy of Sciences knew they could wait no longer and had no choice but to make public the still-imperfect production method for the second-generation powerful insecticide.

Upon receiving the formula here in Yang City, Bai Yinghui ordered its production immediately, but regretfully, in ten days’ time, only this small amount had been produced.

Moreover, not only was the production process complicated, but the cost was also quite significant – essentially, every pound of second-generation powerful insecticide required a full 100,000 Huaxia Currency.

In the current situation where funds were tight, he dared not to mass produce it.

"Then pass down the order and distribute the second-generation powerful insecticide to the various rescue teams, and hope that it can achieve the expected effect," Bai Yinghui said to Jian Hua before turning his attention back to the battlefield in front of him.

At this time, the vanguard of the Mutated Insect Army had already passed through the coverage area of the powerful insecticide and was about to close in within 50 meters of the city wall.

On the city wall, soldier after soldier equipped with flamethrowers was already in position, waiting. As soon as the mutated insects entered the 50-meter range of the flamethrowers, they pulled the triggers without hesitation.

In an instant, long tongues of flame burst forth from the nozzles, covering the advancing Mutated Insect Army below.

This time, it wasn’t just flamethrowers being used – soldiers above hurled down bottles filled with flaming oil one after another. In no time at all, the area below the city wall turned into a veritable sea of fire.

The mutated insects at the very front were almost instantly devoured by this sea of flame.

Even though these mutated insects had reached the Second Order and some had defensive power so strong that even swords and knives could hardly hurt them,

they were ultimately carbon-based life forms. Under the scorching flames, even the toughest carapaces quickly blackened, distorted, and cracked apart, and their life force rapidly diminished.

However, these mutated insects were not about to resign themselves to death, waiting to be burnt alive.

Some moved rapidly, trying to cross the sea of fire at the greatest speed to reach the top of the city wall.

But many more, following their animal instincts, rolled on the ground, trying to extinguish the flames on their bodies.

Under normal circumstances, it would be unrealistic for them to attempt to snuff out flames with rolling once their bodies were smeared with the burning oil.

But here is the problem: outside the city walls was the wilderness, and these were all Second Order mutated insects. Even those the size of a fist could unleash the force of dozens of pounds.

As they desperately rolled around, even burrowing into the ground, dust and soil flew everywhere, filling the air.

The dirt covering them really did extinguish the flames on their bodies quite quickly.

And not only that, as they churned the earth, the sea of fire that had been continuously burning also visibly died down.

This unexpected scene before his eyes made Bai Yinghui clench the corners of his mouth; his expression gradually turned grim.

Because this meant not only that they would need to consume more fuel to maintain the sea of fire, but also that its effectiveness would be greatly reduced.

"Damn it! Why didn’t we think of this earlier? If only we had paved this whole area with cement, let’s see how they would still dig," Bai Yinghui gritted his teeth.

Jianyi remained silent at his side. This was a colossal engineering task. Even if they had known in advance, they probably wouldn’t have done it; wouldn’t it have been better to raise the height of the city wall by two or three meters?

More importantly, as the soldiers reacted and threw more burning bottles, the sea of fire could still be maintained.

However, a reduction in power was inevitable, and with the example set by those first mutated insects, most of the ones that came afterward and could burrow chose to do so, resulting in an even lower effect.

But even so, as they passed through this sea of fire, nearly one-third of the mutated insects were directly burnt to death.

And even if they weren’t killed instantly, their condition had already declined drastically after first being eroded by the toxins in the powerful insecticide and then being burnt. Whether they could retain even half of their prior state was debatable.

However, they still couldn’t launch an attack on the city wall, because there was one last barrier.
