Guo Sen didn't know exactly what this "black fire water" was, but in a literal sense, this thing was related to fire.

What are the liquids associated with fire?

Petroleum.

When Guo Sen was a human, he had not seen what the freshly mined oil looked like, but now he speculated that this kind of oil with dark green color and viscous characteristics should be oil.

Where does this oil come from?

Distracted, Guo Sen separated part of the visual system, and carefully surveyed the area.

Soon, he found a swamp not far from the lizardfolk tribe.

Beneath the swamp lies a large oil deposit.

There was a small spring-like place, slowly gushing out a dark green goo with a very small flow.

Did the lizardmen discover the oil......

So what are they going to do with this?

It's not hard to guess, though.

Turning his gaze back to the lizardmen, Guo Sen saw that they plunged the tip of their spears into the oil, dipped them slightly, and then took them out and set them aside.

Soon, dozens of special weapons were ready.

But what do they do next? They don't have a fire source in their hands right now.

But such worries seem unfounded.

Guo Sen saw that a small group of lizardmen were holding torches that were still burning, and immediately approached here.

Did they really prepare this tactic in the first place?

He shifted his gaze to the tribes of primitive people.

The people inside were also nervously preparing for the battle.

It has to be said that the tall leader still has two brushes, and while he instructs his people to practice spearmanship, he lets the rest of them operate the blast furnace and constantly smelt new weapons.

In Guo Sen's opinion, this leader seems to want to give full play to the "spear-throwing" skills and strike at the lizardmen from a long distance, preventing them from approaching him.

Use a strong wooden fence as a barrier to effectively kill lizardmen.

However, they definitely did not expect that the terrifying monster in their eyes had already mastered more powerful skills.

"Chief! The monsters are coming! "One of the primitive men in charge of the sentry saw the lizardmen through the gap between the wooden fences.

"Get ready to fight! Climb to the top! The tall man gave the order, and all the fighting forces gathered under the wooden fence.

Guo Sen saw that they had put some rocks and planks and the like on the soles of their feet, and the height barely poked them out of the fence by a small half.

This is probably a means to use the skill of throwing guns to repel the lizardmen, right?

However, the lizardmen stood at a considerable distance, and they did not use the secret weapon in the first place.

This distance should also be the safest distance to avoid the primitive people projecting spears.

As the first to invent and use the throwing gun, the lizard people probably also have a deep understanding of the maximum attack range of the throwing gun.

"Two of you," the leader of the lizardmen pointed to his subordinates behind him.

Two smaller-looking lizardmen emerge.

What is this for? Could it be that you want to attract the firepower of primitive people? Or do you want to measure the attack distance of primitive people?

The two lizardmen put down their weapons, even the ill-fitting skin, and suddenly began to move quickly in the direction of the tribe!

"Launch!!"

The tall primitive man didn't see through the lizardman's tactics, and after he saw those two hateful monsters at an effective attack distance, where else could he care?

Kill one less one!

A few spears, illuminated by the light of the stars, turned into dark golden birds, and after drawing an arc in the air, they flew towards the location of the two lizardmen!

However, the two lizardmen didn't look thin, but their leg strength seemed to be extremely strong, and the moment they saw that the other party's weapons had just flown out, they immediately ran back to the rear!

"Ding!!"

By the time the tip of the spear hit the ground, the two lizardmen had already run back into the group, not even breathing.

A contemptuous smile appeared on the lizardmen's leader's face. Is this the only way to attack the maximum attack range of the skinny place?

So......

The lizardmen with oil-stained spears stepped forward, and soon the torch-carrying clansmen lit the tips of their spears.

"Projection!! Let them know, what exactly is real projection!! ”

The leader of the lizardmen shouted, and dozens of lizardmen stepped forward quickly!

The tip of the spear burned with fierce flames and flew towards the primitives!

"Hide behind a wooden wall! Their weapons can't hurt us! The tall leader gave the order at once.

In his opinion, having an absolute barrier with a wooden fence of considerable thickness is definitely easy to defend and difficult to attack.

At most, those spears flew into the tribe and became their own weapons.

The tall man couldn't help but laugh when he heard the dozens of metal stabbing against the wooden fence.

However.

"Chief, Chief! Fire! Fire!! ”

A clansman suddenly shouted, and the tall man wondered, fire?

What fire?

He looked at the campfires in the tribe, and the flames in the distant blast furnaces......

Wait, how can this smell be so close?

He lifted his stiff head.

Fierce flames, burning with an absolute defense that you thought you couldn't break - the wooden wall!

Flames kept coming out of the cracks between the wooden fences, licking the skins of the primitive people who were still leaning against the wooden walls, and several screams came one after another!

"It's—it's impossible!" He couldn't accept such a thing, what the hell was going on?!

The tall leader hurriedly found a place where there was no smoke, and poked his head out to see what was happening.

Centered on the dozens of spears projected by the monster, the fiercely burning flames gradually expanded their territory, gradually connecting into one!

"Withdraw! Fall back! He fell from a great height, and even limped into the depths of the tribe, despite his already broken foot!

The rest of the people also shouted and fled in a hurry, and some even threw away all their weapons.

The absolute barrier has been completely lost, and all the tactics that were previously worked out have lost their meaning!

Flames engulfed the wooden walls, turning their otherwise sturdy walls into brittle black charcoal.

What can this black charcoal resist?

The tall leader looked at the sky with desperate eyes, as if expecting a rainstorm to extinguish the red of the evil that consumed everything.

Guo Sen didn't care about this.

There is no need for this war to be unfair.

The lizardmen were waiting for the flames to completely burn down the wooden walls, while they were also carefully observing the situation inside the tribe.

Despite the thick smoke, the wooden walls that were gradually shattering and crumbling revealed some of the scenes inside.

The leader of the lizardmen was delighted to see that the hateful minions with spears had been frightened by their fire and had taken refuge further into the tribe.

"Everybody's on orders!"

"Yes!!"

"Preparing for the !! Attack"
