The troll's infinite regeneration physique is not unbreakable, strong acid and fire can prevent them from regenerating, Roland is not good at acid spells, the fire magic has only one "fire strike technique", and the 6th level psychic ability "energy barrage" can also be displayed in the form of "flame barrage", in addition, he can also spit out "high divine power dragon breath" to incinerate trolls. It's a pity that the killing efficiency of these methods is far inferior to the faction magic arts, even if you use up the magic positions, psionic points and dragon breath, you may not be able to kill all the trolls of the "undead group", and what is more troublesome is that it takes too much time and energy, and Roland doesn't want to be entangled by trolls in a corner of the battlefield and lose his vision of the overall situation.

After weighing the pros and cons, Roland decides to summon the "thug" who is better at playing with fire than himself to deal with the trolls. Touch the "High Beast Taming Bracelet" with your fingertips, and call out the quasi-legendary flame dragon Balle with telepathy.

The three-colored bracelet inspired the magic brilliance, and the red ribbon seemed to come to life, transforming into a hundred-foot-long fire dragon and soaring into the air, the scales on both sides of the spine being stirred by the hot air gushing out of the body, making a loud whistle sound.

"Lazy Dragon, help me take out those trolls, and be careful not to hurt the half-giants and mechanical armor." Roland admonished.

The dragon rolled his eyes in disgust, looking like a rebellious child forced to obey his parents' discipline, leaned over and let out a dragon roar, and the invisible dragon power poured into the ears of the fierce battle below, and the trolls, half-giants, and dwarves in mechanical armor were all shocked and fell into a stupor for a moment.

Spell Expansion, Firestorm!

Balle roared and then spat out a string of dragon spells, and the furious magic turned into flames that enveloped the battlefield below, and a sea of fire appeared in the Gobi Desert. But a closer look reveals that it was only the trolls who were scorched by the flames, and the half-giants and armored knights who were also in the flames were in an empty space protected from the flames, just sweating from the pillars of fire that rose up at close range.

Roland felt a little relieved when he saw this scene. Although Balle was a perverse man and not very smart, he did his best to comply with his requests. This flame dragon is proficient in all spells in the fire element realm, and can also release a "meteor burst" that is more powerful than the 7-ring flame storm in the form of a spell-like spell, but he chose to release the flame storm because this spell has its own "shaping" function, which can isolate the area where the friendly army is located within the coverage of the spell and avoid the flames, which shows that this lazy dragon's mind is still very delicate.

As for the trolls scorched by the firestorm, their dry skin was set on fire, and they struggled and rolled in the flames and wailed. After a brief moment of consternation, the Half-Giant Militia and the Armored Knights took the opportunity to fight back with spears or large sabers against the trolls struggling in the fire. Their attacks can't kill the trolls, but they're enough to cut their life force and prevent their enemies from escaping the fire, and it won't be long before the trolls are scorched by their own flames and completely devoid of their ability to regenerate.

The leader of the "Undead Regiment", "Mad Demon" Koze, was also hit by the "Flame Storm", but this powerful troll did not fall, and roared into the sky in the middle of the fire, throwing the javelin in his hand with all his might.

Yanlong Balle shrank his head to avoid the javelin, and was deeply enraged by this old ugly ghost who still dared to resist, and opened his mouth to spew out a stream of magma, which confused the "mad demon" Koze. Thick, scorching lava flowed from the old troll's body, falling off along with the charred flesh, revealing Bai Sensen's bones.

The old monster let out a terrible cry and staggered out of the fire, and with each step, a footprint of lava appeared under its feet.

The sight made Roland feel sick to his stomach and swung his sword "Durandal" to split the old troll in half from head to toe. The torn body fell to the sides, still wriggling and convulsing in the sea of fire, and still had a glimmer of life before it was completely burned to ashes.

"What's that?"

At the moment when the "mad demon" Coze split his body in two places, Roland's keen vision caught a small glowing object falling from his neck, and the system then sent a prompt: Discover high concentration potential!

Roland flew over without thinking, rushed into the sea of fire with his special physique that was immune to fire-based damage, grabbed the metal flat box that emitted potential fluctuations in his hand, and flew out of the fire. Looking down and looking closely, the rusty copper box was connected to a green rust mottled chain, which had been cut off by Durandal's sword qi.

Roland thought back for a moment, and it seemed to be the string of ornaments that "Mad Demon" Coze had worn around his neck before. The bronze flat box originally contained a delicate lock, which had already been violently dismantled by the old troll, and Roland opened the box without any obstacles, and found a white candle the size of a thumb inside, and a strong aura of potential hit his face, making him hold his breath.

System Prompt: Discover a high-level magical artifact! Is potential extracted and identified?

Roland shook his head and smiled, choosing not to identify it for the time being. This very inconspicuous candle head contained 10 degrees of potential, and it would take him a while to fully absorb it, because he didn't want to waste time on the battlefield, and secondly, he didn't need to identify what kind of treasure it was.

The copper box in which the candles are stored is hot with flames, and the surface of the candles shows slight traces of melting. Roland hurriedly took the candle out of the copper box and carefully wiped it clean.

The flame dragon Balle burned the "mad demon" Koze to ashes with a mouthful of "thick phlegm", and added two "flame storms" to light the remaining trolls on the battlefield into torches, helping the armored knights and half-giants to remove the threat, and at the same time completing the tasks assigned by Roland before. At this moment, he was bored, turned around and flew back to Roland, and when he saw that he was concentrating on something, he came over curiously. When he looked down, he saw that it was just a candle head, and he couldn't understand why Roland couldn't put down such a ubiquitous thing. Disappointed, he suddenly thought: "Since there is a candle here, and Ben Shuailong can spit fire, let's light it!" ”

Roland was wiping the candle when he suddenly noticed the heat rolling around him, and when he turned his head, he saw that the flame dragon Balle puffed out his cheeks, and there was a flame surging between his teeth, obviously intending to breathe fire at the candle head in his hand.

Fuck your sister! Roland flew up and kicked Yan Long in the face. Balle was kicked by him, raised his head and spewed a breath of dragon breath into the sky in an instant, and then lowered his head to look at Roland, with a clear shoe print on his face in addition to grievances.

"What are you looking at?" Roland counted him down angrily, "Ruined this precious 'prayer candle', Lao Tzu skinned you stupid dragon!" ”
