At this time, he often pondered for a while and said:

"We were fighting fiercely with the patrolling giant ant before, and the reinforcements hadn't arrived yet. Why did this group of monsters come so soon after we killed it? This shows that there must be some way for these giant ants to transmit information to each other."

After Du Yuqi heard what Meimei said, his eyes lit up and he said:

"You're right. According to my research on ants, ants communicate with each other mainly through secreted pheromones. They receive pheromones secreted by their companions through the antennae on their heads. The giant ant we killed must have secreted pheromones representing danger and seeking help before it died, so its companions arrived quickly."

Every time I heard it, my eyes suddenly lit up:

"Isn't your plane that backward and primitive? You've even figured out something like this?"

Du Yuqi shrugged and said:

"Come on, a world without magic is not necessarily a barbaric world."

He always continued:

"Then tell me, how is this pheromone transmitted and then received by the other giant ants?"

Du Yuqi frowned and thought for a while:

"This stuff is supposed to be colorless and odorless, but strictly speaking, it should be transmitted through the sense of smell."

"That's all." Meimei snapped his fingers excitedly and said, "Now that we know the transmission route of this pheromone, why don't we find a way to block it? You see, the giant ant didn't ask for help until it was killed by us, which shows that these guys don't have enough manpower. So as long as we can make a quick decision and act quickly at the critical moment, we don't have to be afraid of them."

At this time, the Steel Bear Knights have begun trying to build bunkers, fortresses and other permanent war buildings outside the safe zone. At the same time, a large number of soldiers are queuing up to go out. These soldiers are armed to the teeth and well-trained imperial soldiers. Their goal is to lure and kill those mutant monsters that can fly freely in the air. These guys are too threatening to those who go out, and they must be included in the targets of elimination as soon as possible.

The Steel Bear Knights from top to bottom have unanimously agreed that this sealed land is full of dangers and opportunities, and that the benefits that can be obtained are staggering, so they have placed all their focus on it, issued an emergency mobilization order, and mobilized all their war potential.

At this time, Du Yuqi finally understood why this powerful knight group could become the main force of the imperial army! The terrifying war weapon "Steel Bear S9" controlled by the combatants was thrown into the battlefield. This is a war weapon designed based on the legendary War Lord G series. It is a powerful mechanical violent bear that can only be controlled by eleven people.

Once this kind of combat weapon appears on the battlefield, it will inevitably cause a bloody storm that will shock everyone!

At the same time, the Steel Bear Knights also have a series of tactics that are centered around the Mechanical Violent Bear, a war weapon. They will allow the Mechanical Violent Bear and the soldiers of the legion to complement each other and work closely together, similar to the infantry-tank coordination tactics on Earth, to produce a powerful effect of 1+1 greater than 2.

Under such circumstances, an extremely fierce battle broke out outside the safe zone. The first to suffer were a large number of mutated giant mosquitoes. These guys who relied on their flying ability to rush forward finally hit a wall today and began to die in large numbers.

Secondly, there is a mutated two-headed bat that can fly in the air. This kind of two-headed bat usually travels in groups of three or five. The number is not too large, but the lethality is very great. One head can perform a skill similar to the "Soul-Eating Hand" of a berserker, biting the enemy and inflicting heavy damage to it, while the other head can spit out dark magic curse arrows. It can be said to be a dual cultivation of magic and martial arts. Even BOSS-level two-headed bats can spit out range attack magic such as "Soul-sucking Dark Power Wave".

At the same time, the bloody smell produced by the fierce battle also attracted a large number of predators. For example, a mutated giant scavenger worm would attack from the underground. It had an extremely large mouthpart, a large number of ring-shaped sharp teeth, and a body length of seven or eight meters. The proliferative glands on both sides of the body would secrete a large amount of mucus that covered the body and could even absorb a large amount of magic damage.

Because of this, the mucus from these giant carrion worms is extremely valuable. It can be used to create items or alchemical potions that can absorb magical damage. Anyone who is an enemy of magic professions will definitely want to get their hands on this thing.

However, it is extremely difficult to hunt this giant scavenging mutant worm, not only because of its amazing strength, but also because this guy has the ability to easily drill into the ground. Even if it is injured, it is difficult to prevent it from escaping. If these giant mosquitoes in the air want to escape, there are still many long-range attacks that can intercept them, but there is really a lack of such means for attacks launched underground.

The fierce battle lasted for two or three hours. During this time, Du Yuqi and others also went to help fight. The monsters in the sealed land were also attracted here one after another. A terrifying vortex of flesh and blood had formed here. A large number of predators rushed here with hunger and expectation, but in the end, their bodies became part of the growing vortex of flesh and blood...

However, although the battle was fierce, the Steel Bear Knights did not suffer heavy losses. The main reason for this was that they were fighting with the support of the safe zone formed by seven magic circles. Once someone was injured, they only needed to escape two or three hundred meters away and then return to the safe zone for treatment. At the same time, the auxiliary magic and various healing spells released by the large number of paladins who participated in the battle also saved the lives of a large number of soldiers on this battlefield.

Suddenly, a giant mutant worm as tall as a three-story building broke out of the ground, and an extremely shrill hissing sound came from its mouthparts. Its head was raised to the sky in despair, and a human figure was resting on top of its head. Although the giant mutant worm kept struggling, the human figure seemed to be nailed to its head, with no intention of being thrown off at all.

Suddenly, a huge cross illusion flashed behind the figure, and then a ball of light like the scorching sun quickly formed in the palm of the figure's hand and soared straight up to the sky. After the ball of light floated in the sky, all the attributes of people directly illuminated by its light were improved by half, and even their attack speed and movement speed were within the improved range. The situation on the battlefield was reversed instantly.

After the light ball lasted for about two minutes, it suddenly changed from pure light attribute to pure dark attribute! It fired seven dark attribute slender light beams at the monster below for continuous tracking and bombardment. Finally, the seven slender light beams merged into one, turning into a sharp dark element spear with surging flames around it!

At this time, a pair of light wings appeared behind the figure standing on the head of the giant mutant worm, and he jumped up!

Then he caught the spear formed by the dark element and stabbed it straight down, directly penetrating the head of the giant mutant worm. However, the giant mutant worm had a very high dark resistance and was still struggling. However, holy light suddenly shone on the palm of the figure, and a ball of extremely pure light element was injected into the blade of the dark element spear!

The two completely different elements of light and darkness met in an instant, and then... a terrible explosion occurred!!
