The goal is set, but how to implement it is a big problem.

Trap Master Collen has mining skills, he placed a detonation trap outside the mine, and after activation, he drew a rough topographic map of the inside of the mine based on the feedback of the shockwave. Twists and turns, high and low, up and down, there is no accurate number at all. And there are a lot of forks, stretching in all directions, and I don't know where the boss is hiding.

"As the saying goes, 'Nine Songs of the Yellow River', I'm afraid this mine cave is more than ninety songs......" Looking at the map drawn by Corrain, the panda couldn't help but sigh, "How can this be set on fire so that it can burn all the way to the innermost?"

Everyone looked at each other.

Hot on and cold on the bottom, circulating convection. It's easy to burn the flame from the bottom up. But if you want to burn the flame from above, it is as difficult as climbing to the sky. In the twisting mine, I don't know how many sections are staggered up and down, and it is not easy to burn the fire to the end of the mine!

Arson is also a craft, and several bandit traversers in the guild have this craft. But none of them know this craft - this is not easy to learn, either through a profession, or they have to be trained for a long time. It's definitely too late for them to train now.

"Let's try it first. After some discussion, they reluctantly came up with a solution that was not the way to go.

They took some oil and asphalt from their supplies, mixed them with scrap wood from the old mines, made a half-man-high ball, and pushed it into the mine and set it on fire.

As soon as these flammables encounter an open flame, they quickly burst into flames and quickly turned into a large burning fireball. Raisha propelled it forward with her self-taught wind spells, and soon Gollum rolled deep into the mines.

Then, a terrifying roar came from inside the mine, and dark green poisonous gas came out in large clusters. The traversers hurriedly retreated, narrowly avoiding the poisonous gas. But even so, they were dizzy from the stench of these poisonous gases, and had to retreat again and again, far away.

From a distance, I saw that the mine had completely changed its appearance, and dark green poisonous gas was accompanied by black smoke and sparks, constantly coming out. And it's not just smoke and fire coming from the entrance to the mine, but many of the vents are also spewing smoke and sparks.

At first glance, it looks like the mine has turned into a strange beast that is constantly spewing out fireworks.

"Huh, why did it burn so badly?" asked Raisa, confused.

Everyone shook their heads, not understanding why.

According to their estimates, the fireball rolled in, and at most it burned all the way, emitting some smoke, and scaring the monsters inside. If you want to say what you can burn, you can't be sure at all.

"Could it be that this mine produces coal in addition to copper ore and iron ore?" the panda muttered to himself.

Corrain's eyes lit up and he said, "Inside, woo, there's a wooden frame, woo, there's a dried corpse!"

Everyone suddenly realized that they finally understood why.

In order to prevent the mine from collapsing, there must be many wooden frames used to support it, plus those zombies that have dried up without any moisture and have completely turned into flammable materials, this mine is not a flammable product!

At this moment, Yunero was suddenly stunned for a moment, and whispered, "I'm thinking...... Is there any 'gas' in the mines on the earth?"

Everyone was also stunned, and there was a little more solemnity and worry in their eyes when they looked at the burning mine.

Gas explosions are the cause of famous mining accidents, but ...... Copper ore iron ore, will there be a gas explosion?

After a while, the smoke and fire from the mine became more and more abundant, and the scene seemed more and more alarming. As the sun gradually sinks in the west, the light and heat are decreasing, while the shadow of the mine is getting bigger and bigger.

Suddenly, the panda realized something, drew his sword and thrust it into the ground, shouting, "Holy light shines, sweep away evil spirits!"

Golden light emanated from him, illuminating a large area around him. A sharp cry came from the shadows beneath everyone's feet, and several shadows rose from everyone's shadows, ignited in the holy light, and disappeared in an instant.

"Retreat first!" saw through the BOSS's methods, but the panda didn't dare to relax at all, and shouted, "Let's retreat a little farther away and come back tomorrow morning!"

Of course, there was no objection from the crowd. That moment had already made them all secretly frightened - although these monsters lurking in the shadows may not be able to hurt them, but before they knew it, they were sneaked into their surroundings, and anyone would be uncomfortable.

In this case, even Yunero had no intention of winning or losing, and unanimously agreed with Panda's proposal.

So they withdrew far away in one go, and even didn't even want the previous camp, and retreated to a farther place, before the panda started to arrange the sacred enchantment, and then built a camp inside the enchantment.

Although there was also a sacred enchantment in the previous camp, the enchantment is like a machine, and the newer it is, the more reassuring it is.

Just as they were working on their new camp, Panda received a private chat from Raymond, the leader of the Northern Front team.

"We've got it done, that 'Ghost Fire Flange' is just a ghost, and his subordinates are also a group of ghosts. Although he failed to obtain the 'Demon King's Heart', he achieved a lot of 'Tears of Sighs', especially Flang's own, whose quality is actually purple, which is very high-end. ”

Panda sighed and replied: "It's not going well on our side, the terrain of that mine is complicated, and the boss's subordinates are a group of weirdly smelly zombies, we don't dare to rush in, and we are currently setting fire to the mountain." ”

"Set fire to the mountain, and sit in the prison. Can't you think of something more creative?"

"We can't really figure it out. Panda smiled self-deprecatingly and asked, "How's the situation on the Western Front?"

"I haven't asked yet, I'll ask first. ”

After a while, Raymond sent a message: "The Western Front is not going well with you, and that tree man can actually burrow into the ground." They've hung up a man, and they're already surrounded by 'dead dryads'...... Let's not talk about it, we have to rush to support. ”

"Be careful!"

"Don't worry, even if the dryad becomes a boss, the fire resistance is also negative. It's a big deal, I'll learn from you, set a fire and burn the whole forest!"

"How long should I sit on the base of setting fire to the mountain, and setting fire to the forest?"

"Haha!"

Raymond opened his eyes, ended his private chat, and shouted to his gray-faced companions beside him: "There's no time to rest! Let's hurry to the Western Front! The unassuming birdmen are surrounded by a group of tree spirits, waiting for us to save their lives!"

"They can be beaten by the task boss, how weak they are!"

"How's it going on the Eastern Front?"

"It's okay on the eastern front, and I'm fighting with the boss. Although the panda is impulsive in fighting, he still has a lot of brains when he does things, so don't worry about him. ”

The group quickly packed up their things, and before they even had time to wipe the dust off their faces, they hurried to the southwest......
