Not once, Lukka immediately began to cast spells on the second barrel, and he had already experienced this kind of thing countless times since he failed to try a new spell.

With the rhythmic chanting of the incantation, the second barrel lives up to expectations...... It blew up as well.

It's just that after this explosion, it was not the green powder that spilled out, but the power of plastic energy was transformed into a burning flame before the cuimian mineral powder was thrown out, and the powder was burned out in an instant.

Now, in addition to green, the goblins have an extra layer of black ash on their faces.

"You see, there's still progress. Lukka said lightly, but sweat kept running down his forehead, washing the black ashes on his face into furrows. Now, his goblin-like face was covered with black and green stripes, and from a distance, it looked like a watermelon with a hooked nose.

He turned his head and continued to destroy the remaining wooden barrels, and the sound of the explosion and the sound of the distant stone shell spider mother hitting the rock were quite harmonious at first glance.

Gavin watched Luca consume the barrels, estimated slightly, and called over a few mine guards and ordered, "You better bring more barrels of this kind, and there is mineral powder in them." ”

"No, no, I've found the trick!" Lukka actually cast a spell while listening to the movement.

There was only one of those barrels left, and he held his breath and raised his right hand again.

Gavin and the other goblins hurriedly covered their ears and hid behind the corner of the house. Now, not only do they have to worry about the destruction of the Stoneshell Spider, but they also have to avoid all the conditions that Lukka has created, which is really miserable.

However, after hiding for a while, the expected explosion did not come for a long time, and Gavin trembled and poked his head out.

Lukka kicked his foot on the overturned barrel, and the barrel rolled on the ground in the direction where the goblins were hiding.

"Do you want to blow us up?" Gavin jumped to his feet, ran more than ten meters, and crouched down again behind the half-cut wall.

"It won't blow up, this time it was perfect. Lukka said and patted McCorbe, "Now, you can weigh it up." ”

The captain of the Mine Guard had brought in the spare trebuchet and ancillary equipment, including several scales, and even a few six-legged lizards to pull the carts.

McCorbe and Gavin's brother worked together to not only weigh it quickly, but also to secure the barrel in the trebuchet's slots.

Then, he looked up at Luca and asked, "Where?"

Lukka looked around, scratched his head and asked, "Where's the mother?"

The squad leader did not relax his observation of the surroundings, pointed to the street in front of him and said, "It has been destroyed all the way in this direction." ”

Gavin walked out from behind the broken wall, wiped his sweat and said, "Maybe it's gone, it's not far from the city in that direction." I don't think I need to blow it up today!"

"What if it turns a corner, what if it turns around?" said Ollie.

"yes, let's go and have a look. The chatter also said.

McCorbe didn't wait for Gavin's order to put a lizard on the catapult, jumped on the front beam of the catapult with the talker, and drove the lizard forward, and Lukka and Ollie also jumped into a car pulled by the lizard.

"That'...... Let's go check it out, but keep a safe distance!" Gavin reluctantly compromised, grabbed a standard protective helmet of the Mine Guards and buckled it on his head, and climbed into the car.

The mother spider moves fast, but the power of destruction is undiminished. Lukka didn't even need to carefully tell which direction it was going, he could track the location of the mother worm by following the debris of the building that had crumbled into piles of stone slag on the side of the road.

After walking a short distance, the eight legs of the mother worm reappeared in front of her.

There are fewer and fewer buildings around, and this is already on the edge of the city. The edge of a city carved out of the rock is not an endless field, but a solid rock wall.

At the intersection of the street and the rock wall at the foot of Lucca is a tunnel about two meters in diameter, which leads to the outside of the city. A tunnel of this size is the largest of the walking tunnels for a goblin, at least it used to be.

Now, the mother worm was constantly moving her long legs, hitting the tunnel, and large rocks were falling from the top. By the time Lukka arrived, the tunnel was gone, not just at the mouth of the tunnel, but probably completely collapsed for a long part of the tunnel.

Judging by the direction of the mother's legs, it has just turned around and is heading in the other direction of the city, ready to start a new round of destruction.

"It really won't go!" said Gavin, sitting on the only crystal nucleus-powered chariot in the group, crying.

Lukka jumped out of the lizard cart and walked over to McCorbe and the trebuchet and said, "Be sure to wait for my signal before attacking, there's only one piece of ammunition." ”

After saying that, he clenched his staff and walked slowly towards the mother worm.

Of course, as a mage with almost zero agility and a negative physical strength, he would not stupidly walk into the range of the female worm's attack, but stopped at a distance of nearly twenty meters.

Lukka had tried seven times, and the last time, he had used seventy percent of the plastic power he could now muster on the flame blast sealed in the barrel, which should be enough to kill the bug as long as it could hit the vital point.

Now, he had to use the remaining thirty percent of his energy to force the mother worm to reveal its vital point, which was its head.

The height of the female worm is half that of the dome of Deep Mining City, and her upper body has been hidden in the stone above her head, running all the way, knocking out a groove in the dome.

Lukka raised his staff and chanted the first incantation.

A breeze began to coalesce, gradually turning into a fierce wind around him, and countless invisible blades were hidden in it. To be precise, the blade in the Wind Blade is not a real entity, but an effect produced by compressing air to a maximum density. Although these blades are extremely sharp, they are only about ten centimeters long at most, and they are used to deal with stone-shelled spiders with hard shells, and they are not even enough to tickle.

Lukka knew this, of course, and he slowly introduced the power of plastic energy into this seemingly ordinary third-level spell.

The sharp blades around Lukka suddenly changed shape, and the small blades fused together to form a long sword that shone with cold light.

Of course, if you look closely, you will see that the blade of this longsword that rotates rapidly around Lukka is actually transparent, and it is still only the product of compressed air, but under the effect of the power of plastic energy, the air compressed to the extreme looks as if it has an entity.

Luka's fingers moved slightly, and the transparent blade flew straight towards one of the female worm's legs!
