Li Ming's order is simple, now the energy turret and mechanical weapons are fired in unison......

As the order was given, a halo of light flickered, and the tops of those tall energy towers all lit up with red light clusters at once.

The players of the Mechanical Legion also quickly turned their gears and targeted a large number of shield enemies outside the city.

Whew!

Boom!

In an instant, countless red balls of light on the city tower fell neatly towards the outside of the city, and countless thick arrows, with the players' magic and arrow rain attacks, flew overwhelmingly towards the outside of the city.

As each red light smashed down into the crowd, the roaring sound of explosions and layers of air waves spread to all sides, and within five meters of the red light landing, there was no longer any standing figure, and there were corpses of shield warriors lying on the ground.

Under the attack of the energy turret, these shield warrior players didn't even have time to shout out the screams before they died, and they were directly killed by the energy light bullets!

And the explosion wave after the light bomb landed, it swept away countless shield warrior players, fortunately, they have rough skin and thick flesh, and if they change to other class players, they will definitely be killed directly.

When they landed in the air, they found that they didn't have much health left, and if it was a player who only had half of their health bar left, they would have turned into corpses when they landed!

Countless players fell to the ground and smashed to the ground with a splash of oil.

This was followed by a furious harvest of mechanical crossbow arrows, and a large number of shield warriors were pierced through their bodies by thick mechanical crossbow arrows, and the health bar quickly fell down!

"Oh no, the enemy is using energy turrets and mechanical weapons, everyone retreat!"

A nervous roar suddenly sounded in the crowd, and the shield warriors who reacted knew that something was wrong, and they wanted to turn around and retreat one by one.

However, when they thought of escaping, they were surprised to find that their feet seemed to be glued to the ground, and they were very slow to move, and some shield warriors could not move at all, and their bodies were just shaking in place.

Yes......

Only then did countless shield warriors see that the soles of their feet were unconsciously filled with thick black slime, and their feet were tightly glued inside, as if they had stepped into a thick thin mud, and no matter how hard they tried, they couldn't pull their feet out......

It's like the feeling of many people jumping in to catch fish after the water in the reservoir has been drained, only to be sucked by the thick mud that catches their feet.

"Damn, their oil drums ......"

Some shield warriors suddenly realized, but it was too late!

They can't move at all now......

Seeing the arrows and magic skills falling from the sky, they could no longer retreat, so they had to raise their shields and try to make a dying struggle.

But the defenders obviously wouldn't give them any chance, and the energy turret began to move its attack position horizontally, specifically targeting the densest places of the crowd to attack, and a huge ball of red light fell into the crowd, like a rag everywhere it went, instantly erasing all the dense crowds......

And the mechanical crossbow arrows are like harvesters, shooting neatly in rows, what penetrating crossbows, scattering crossbows, continuous fire crossbows, charged crossbows and other various crossbow arrows fly by, and rows of players fall to the ground in response!

The attack power of mechanical crossbow arrows is far more terrifying than the player's rain of arrows and magic skills, and the most terrible thing is that the fixed damage of mechanical weapons is more like a natural nemesis for the shield warrior with the highest defense.

No matter how much defense you have, every attack of the mechanical crossbow will take away a certain range of damage numbers, and the bloody shield fighters can't withstand such a fierce attack......

Seeing the enemies outside the city fall to the ground one after another, and the dense crowd disappeared in just a few minutes, the defenders on the city tower suddenly smiled in unison.

A large number of enemies outside the city who were about to rush towards the castle tower were frightened by the situation ahead at this time, and immediately turned around and ran after reacting......

The shield warriors couldn't escape now, they could only watch as the sky was full of black spots and huge red light clusters that kept flying in front of them!

"When the enemy is still half a little left, give them a good time." Li Ming looked at the killing scene outside the city and said lightly.

"Got it, Brother Ming." Kun Shao nodded, carefully staring at the number of enemies outside the city.

In the area outside the city covered by asphalt ore, the enemy was like a stake and was passively beaten in place, and the enemy who could move had already retreated quickly, staying far beyond the fire coverage, and looked at the tragic situation under the city tower in amazement.

"What...... Ordinary players are killed so badly? "The prodigal son of the sky is at the back of the black sea of people, and the line of sight in front is blocked and he can't see the situation at the scene, so he can only rely on the spies in front to send back the battle report.

When he heard that so many ordinary players had not only failed to pose a threat to the city wall until now, but had actually been killed, and now even most of the shield warrior classes would be completely wiped out, which made him even more frightened!

"Yes, the commander-in-chief, they don't know what materials were used, so that the large number of shield warriors who went to attack the city were all trapped in place and passively beaten, and now I am afraid that the whole army will be wiped out!" The spy nodded in reply.

"It's really troublesome now, I didn't expect ordinary players to be so indifferent, if even they can't play a role, we're afraid that we will ...... if we go up," Lone Moon Hanxing said worriedly.

"Let's figure out the situation, it's useless for you to see it clearly, what materials are they using?" The prodigal son of the sky hurriedly asked.

"I couldn't see it too far away, but I saw countless black dots thrown down from the city tower, which looked like huge wooden barrels, but nothing happened after they landed, but the shield warriors couldn't move there......," the spy explained helplessly.

"Throw the barrel and fix the ......" The prodigal son of the sky frowned, puzzled by this strange situation.

"Find out what it is, and I'll wait here for your reply." The prodigal son of the firmament commanded.

"Yes." The spies had to find a way to squeeze their way through the crowd and ask the players in front of them about the situation.

Soon, they thoroughly figured out the situation from some of the warrior players who had escaped and immediately reported it to the leadership.

"The barrel was filled with black oil juice, smashed down and scattered all over the ground, and it was very viscous......" After hearing the news, the prodigal son of the sky stayed there in an instant, this kind of material, he has rarely seen it, and what strange weapons has the enemy invented?

"I seem to have seen this kind of resource." Lone Moon Hanxing said with a deep groan.

"Brother Guyue, tell me quickly, what is this material?" The prodigal son of the sky suddenly asked excitedly.

"I don't think there's anything in the material that's so sticky that it can stick people in place and can't move. However, there is a kind of raw ore with such characteristics, its name is asphalt oil ore, which is a very rare resource, and our legion occupies a collection point of asphalt ore, but the production is too small, it is only ten barrels a day. Lone Moon Hanxing replied thoughtfully.

"What...... Asphalt oil mine! Are you not mistaken? The prodigal son of the sky asked in surprise.

"Probably not wrong, but after this resource is collected, we will immediately hand it over to the craftsman for refining, and there is no remaining raw ore until now, let alone such extravagance as they are, and they actually take the precious asphalt raw ore to use as a weapon, which is a huge waste!" Lone Moon Hanxing said sadly.

The preciousness of the asphalt ore is very clear to him, the leader of the Artisan Legion!

After refining this raw ore, several different materials can be obtained, and each material is necessary to create some high-level items, which can be said to be extremely precious......
