At the northern end of the forest sea is the high and snow-capped mountain range on the top of the mountain, and the forest sea near this place is also high and densely forested, and the streams and rivers that flow from the north to the south from the ice crown mountain range are dense.

After climbing a hill, the duo approached the cave where the goblins lived downwind with their guide.

"I'm back!" said the farmer who led the way, and slipped away.

Charles took out two pairs of binoculars made by the dwarves, handed one to Diana, and took the other one to look around carefully, so as not to be made by the unknown threat.

The cave is located at the foot of the mountain, and there is a clearing in front of the cave entrance. The entrance to the cave is about 1.8 meters high and more than 1 meter wide, and you can see from the outside of the cave that the height of the cave is rapidly decreasing. According to people who have entered the cave, the trend inside the cave is high and low.

It was already past three o'clock in the afternoon, and it wasn't long before the goblins would come out to feed.

"There are no goblins outside the cave. Diana said.

"Safe surrounding. Charles reported.

After inspecting their helmets, leather armor, weapons, and leather boots, Charles and Diana, dressed in homemade gilly suits, began to slowly make their way to the cave.

Diana performed much better than Charles along the way, always using obstacles to block possible views from the hole, her steps were silent, and she was able to step on places that were not easy to slip on every time.

Charles simply followed her and stepped on her footprints.

Afterwards, Charles asked Diana about this: "Why are you so skilled!"

Diana replied: "We can shoot wild boars in 100 steps, and if we want to go to 985, we have to hunt wild boars with daggers, which we practiced in the third year of high school." ”

A few meters away from the cave, the two climbed in the bushes to make final plans and preparations for the next attack.

Just kidding, the two of them were only eight years old, and they were still kids without a golden finger, and they hadn't planned to do that when they saw the mission briefing in the first place.

Just taking a weapon into a cave with narrow and complicated terrain and slashing is too sorry for the wisdom of the traverser.

What's the best way to deal with enemies in caves and tunnels?

Naturally, the number one is the cloud burst bomb.

The second place is to fill the hole with gasoline and light a fire.

Almost all other methods have appeared in "Tunnel War", nothing more than smoking, watering, and the worst way is to let people in.

The existence of oil has not been found in this world, and I don't know if it is due to a technical problem with exploration or something else. Therefore, the provision of gasoline can only be removed.

Charles and Diana were fully prepared after establishing the idea of winning a battle in harsh terrain conditions based on existing weapons and equipment.

There are no cloudburst bombs, but the dust explosion can be tried, and maybe it can buy some time for the second step of the operation.

It's just that in the era when there was no industrial production equipment, extremely finely ground flour was a first-class luxury. The baron and the poorer viscount usually ate semolina with bran, and when guests came, they had the bran sifted off and then served to them. Those finely ground flours need to be sieved several times and repeated grinding to get them. Fortunately, the water and wind resources near Avalon City are quite abundant, and the nobles who come here for vacation can come to whatever they like for their own face, so you can find flour here that barely meets the requirements.

For this operation, Charles Fox almost emptied the special flour for Elizabeth at the Big Foot Hotel.

Although the heart hurts the dinar, the money is not important compared to the small life.

“3...... 2...... 1...... Action!"

As soon as Diana gave the order, Charles immediately rushed to the edge of the cave and threw into the hole the excellent flour that had been unpacked in the barrel from the storage ring.

Diana also rushed to the cave not far from the cave with two daggers, and at this time there was a noise in the cave. She immediately sparked the dagger with a hurricane, blowing the flour from the ground into the cave. Then she changed her dagger, and a large fireball shot out of the dagger and flew into the depths of the cave.

Diana, who released the fireball, immediately turned and ran, quickly avoiding the direction of the cave entrance.

The female man never looked back at the explosion.

With a loud "boom", a pillar of fire rushed out of the cave. By this time, Diana had already jumped forward and jumped behind the big tree that had been selected early in the morning.

As soon as the pillar of fire dissipated, Charles rushed out of hiding and into the cave.

Not far from the entrance of the cave lay a charred and shivering goblin, presumably a sentry on duty near the entrance of the cave, and he was greeted by a large fireball just now when he was about to come out to see the movement.

In the depths of the cave, quite a few shouts began to be heard.

After replenishing the poisoned dagger for the goblins on the ground, Charles immediately threw the large amount of wood, grass, and herbs prepared in the storage ring into the cave.

Thankfully, the few storage rings in his hand were high-end goods, and the space inside was almost filled with things like shavings and wood chips from the woodworking workshop, flammable pine wood, hard, dense firewood that was resistant to fire, poisonous herbs when burned, fresh and tender pasture grass that was easy to produce a lot of smoke when burned, and a bucket of vegetable oil to fuel it.

It took Charles only a short time to pile the flammable items inside and out not far from the mouth of the cave, and then set the shavings on fire with a few small fireballs.

Diana was now at the edge of the cave, and she used the dagger she used to cast the hurricane spell as a blower.

When the goblins in the cave were smoked near the entrance of the cave, the fire on the edge of the cave had already begun to burn violently, and they had no way to extinguish it.

After a while, when the flames of the fire began to weaken, Charles outside the cave squatted on the ground and said to Diana behind him: "Come on, I can still withstand your little body." ”

Diana gently twisted Charles's ears and said, "Don't take the opportunity to mess around." ”

The corners of Charles's mouth twitched, and he said, "I'm not Lolicon, you have to worry about it until ten years later." ”

Then the strength of the little hands on Charles' ears grew.

Diana got on Charles's shoulder and held Charles's head, and Charles stood up.

Charles held Diana on his calf crossed over his chest with one hand, and with the other hand he held a dagger blower to blow the wind on the fire in the cave.

The "crackling" sound of burning wood came from the cave with the goblins' roars and shouts, and the smoke billowing from time to time caused the goblins to cough from time to time.

Diana, who was riding on Charles's shoulder, took out a roll of cloth almost two meters wide from the storage ring in her hand, and then used an iron nail to nail the end of the cloth roll to the top of the hole.

Although Charles used a dagger blower to blow the toxic smoke into the cave, the heat coming out of the cave made Diana uncomfortable.

With Charles' cooperation, Diana finally nailed the fireproof and waterproof cloth she bought in the store of the Adventurers' Guild to the hole like a door curtain. This two-meter×two-meter cloth is generally used for adventurers to rest on the ground.

After ten minutes of hard work, the two of them finally sealed the cave tightly with this piece of fireproof and airtight cloth and a bucket of purchased slime glue.

"That's it. Charles clapped his hands, looked at the sealed hole and said, "Just wait for the goblins inside to die of smoke or carbon monoxide or carbon dioxide poisoning." There is a fire at the entrance of the cave, and it is not easy for the goblins to rush out. ”

Charles looked back and saw Diana in tears.

"What's wrong?" Charles hurriedly walked over to her, wiping tears from her face with his dirty sleeves.

"It was smoked just now. Diana said.
