The scorching fireball hit the dense wall of thorns, and immediately exploded into countless jumping fire snakes, igniting all the combustible materials around it, including those thorny plants, as well as cannon fodders hanging on them and struggling constantly, and they have not yet died completely. The burning wall of thorns turned into a demon's barbecue grill, and a disgusting burnt smell drifted into the noses of the defenders along the wind.

If there is no accident, the ignited vines will burn out within a minute, but Lancelo guessed that the casters who made these vines must have a solution.

Sure enough, he immediately sensed a large-scale magic wave. This time it was a light blue magic aura, corresponding to a change-based spell. The original green vines quickly turned gray, and their weight seemed to have changed, and they no longer continued to roll under the collision of the demon cannon fodder.

In just a few breaths, these vines seemed to have turned into stones. The surface was still burning, but what was burning was actually low-level demons who were still hanging on it (and constantly bumping into it). The screams from these poor cannon fodder almost made people feel insane. The powerful vitality of the demons and their resistance to flames were a curse at this time, making their death painful and long.

This magic is the response of the old elf Quillion. He had long expected that the demons would set fire, so after completing the summoning of the wall of thorns, he immediately began to prepare this magic of turning wood into stone. Petrochemical cannot be completed instantly, but since this is a process from the outside to the inside, as long as the surface of the plant becomes a stone, the combustion will stop.

In addition, since he only needs to turn the ignited vine into a stone, the preparation time for the spell is much shorter. Of course, he can summon a stone wall from the beginning, but that will not be able to delay the enemy.

This is all his arrangement after he came, and the spells were all prepared on the spot. The time required to memorize a spell depends on the complexity of the spell. Generally speaking, it takes at least 1 minute to prepare for each ring level on average. The spell of the thorn wall in front is a 6-ring spell, and the wood-turned-stone behind is a 5-ring spell. It took a little time to prepare these two spells, but fortunately I caught up.

But this is their limit. The joint casting ceremony requires each caster to prepare the same spell, and Pascoll's defenders had not prepared for joint casting before, so they could only temporarily remember the spells. As it turns out, the two intermediate spells are already the limit allowed by time. If they drag it longer, the city wall will probably fall.

After turning into a stone, the thorns on the thorns are still sharp, but they no longer have the toughness of being a plant. The demons soon discovered that the stone thorns could be easily broken, and then they could climb up with the broken thorn roots.

The petrified thorns are a column with a radius of about five feet. Although they are not high, their surface is not flat, so it is not that easy to climb over. Moreover, during this process, they have to be careful of the archers on the tower, their companions pushing behind them and burning corpses.

As if they felt that their troubles were not enough, the yellow light of the spell system lit up again, and a large amount of oil fell from the sky and splashed on the thorns, and was immediately ignited by the remaining Mars.

Unlike vines rich in moisture, the flammability of oil is much stronger. Any place that is splashed is immediately covered by the flames soaring into the sky. The low-level demons who are climbing over the petrified wall of thorns are burned and screaming. The demons are indeed resistant to flames, but most of them cannot be completely immune to this kind of damage like the devil, and they cannot ignore the pain caused by burning.

Unlike the situation where they were nailed to the spikes and could not escape, these low-level demons who were burned and burned had long forgotten the horror of the supervising team. They jumped back from the burning wall of thorns in a turbulent manner, creating more chaos in the already crowded group of low-level demons.

Demons are not understanding races. Not only will they not help extinguish the flames on their similar people, but they use their claws to drive away the fire people approaching them. In such a dense occasion, this will inevitably hurt others by chance, which will trigger more battles.

Chaos quickly spread among the crowded demon cannon fodder. This was the first time that Lancelo had experienced such demons participating in. War-level battles. In his incredible eyes, the group of demon army collapsed. They seemed to be about to end the fate of this fortress, but at this moment they were killing each other crazyly.

After coming to the abyss for so long, he was not unaware of the habits of this demon - irritable, cruel, murderous and extremely insidious (perhaps the succubus is the only exception), but the collapse of an entire demon army on the battlefield due to internal fighting still opened his eyes.

Greedy Skill is just a one-ring spell. Due to its practicality, almost all mages will prepare this magic. Using greasy Skill is a temporary intention of the old elves. Unlike the dwarfs who follow the rules, the elves are always very creative when fighting. But after using this spell, Quillion had no other moves. He waved his hand, and the elves sages who were originally surrounded by him immediately led their apprentices away. They were going closer to the city walls to provide direct support to the defenders in the battle.

At the same time, the battle on the city wall continued, and the two hundred people brought back by Lancelo played a decisive role. They bravely rushed directly to the most anxious places in the battle, blocking the most fierce enemy, and the heroes in each story that were recognized would greatly inspire the morale of the defenders.

Unlike those particularly high-profile and popular "returning heroes", Lancelo fought extremely low-key. His giant sword would not shine, and he would not shout out the names of moves when chopping people. But before he knew it, a large number of people were empty. The reason is very simple. The efficiency of human knights to kill enemies is too high. Staying by his side will make him feel "participated" in fighting.

But the attacking demon saw a vacant city wall. Only a bloody knight was still fighting stubbornly. When they jumped onto the city and found the ground full of broken corpses of the same clan, they realized that something seemed wrong.

In the distance, the atmosphere in the main formation of the demon army gradually became strange. Cang Ye was still floating quietly in the center of the demons. The plain curtain blocked its face and hid its emotions, but an invisible pressure made the surrounding followers almost breathless.

The most ugly expression was a shriveled and dark demon who looked like a burnt dwarf. He wore a gorgeous armor covered with gems and had three scythe-like red fingers on his palm, as if he had been soaked in blood for a long time.
