nTreasure Chest Monster Meat: Each Treasure Chest Monster meat has a very small amount, but each piece of meat is very elastic. It is the essence of the Treasure Chest Monster. If you consume it frequently, it will give you a mouth full of good teeth. Currently, it has a three-star satiation index. Overall score: 66

nTreasure Chest Monster Blood: It is filled with the smell of rust and has no nutritional value. It is combustible and can ignite at a single point. The temperature of the flames is extremely high.

nKlein looked through the details and kept the flesh of the treasure chest monster away.

nNext, he opened the real iron treasure chest.

n“Fishing machine?”

nKlein couldn’t understand how to fish in the catacombs world.

nCould there be fish beneath the soil?

nHe hadn’t encountered any in the past few days of digging.

nHe thought for a moment before saying, “Two manufacturing blueprints and a medium-sized map. It’s not a loss to open the chest this time.”

nKlein muttered to himself.

nThere was naturally no need to elaborate on the medium-sized map. He could check the notes for the next five catacomb caverns and plan the route ahead of time.

nThe other two blueprints…

nExcellent Gas Mask: It is a daily rune device. It can guard against most poisonous gas and provide the wearer with purified air. The size can be customized.

nPerfect Sand Fishing Device: A daily rune device. Add a little bait, bury it under the sand, and it’s easy to catch Sand Fish.

nBoth devices have good uses.

nWith the gas mask, he would able to access some of the gas chambers.

nNot to mention the fishing machine did not need to operated. It could just be buried in the ground and could fish itself..

nHe just didn’t know if Sand Fish tasted good!

n“Learn it,” Klein recited.

nTwo blueprints disappeared.

nOpen the manufacturing list.

nThe materials for the two runic devices were sufficient.

nKlein didn’t plan on forging them for the time being.

nHe would talk about it when he needed it.

n“Medium-sized map! This is good stuff.”

nKlein spread out a piece of parchment.

nHe had obtained it the last time he looted a corpse.

nThe middle of the map was marked with a red dot, which was the catacomb he was currently in.

nAfter eliminating the previous catacomb, there were only five directions left…

nKlein directly looked for the special item marked on the map.

nRunic Egg.

nSilver Treasure Chest.

nAn abandoned Earth Dragon nest.

nKlein quickly locked onto three locations and planned out a route.

nFirst, he had to enter the poison chamber below.

nThen, he had to dig to the left to obtain a runic egg.

nHe continued to head to the left catacomb, and if he continued digging, he would find a silver treasure chest.

nThe last stop was the abandoned lair of the Earth Dragon!

nKlein lowered his head to look at the hint.

n“I’ll choose this route. If there’s any danger, I’ll just change my route. It’s not bad to turn into this catacomb in the middle. There’s an iron treasure chest.”

n“The first stop is the poison gas chamber. The gas mask has to be forged.”

nKlein looked at Little Fox.

nShe also needed a gas mask!

nThankfully, this thing could be customized, or Little Fox wouldn’t be able to pass through the gas chamber.

n“I’ll make one for myself first.”

nKlein opened the production list again.

nHe selected the gas mask.

nHe confirmed the production.

nSystem notification: Wind Rune-1, Sand-Eating Beast Skin-1, Iron-2, Silver-1, Crystal-1

nSystem notification : Excellent Gas Mask has been successfully forged.

nA mask appeared in Klein’s hand that could cover the entire face.

nIt was made of iron, and the eyes were two transparent lenses.

nThe mouth and nose of the mask protruded.

nThere was a pattern of wind at the breathing area.

nKlein put on the gas mask. It was just the right size and could breathe normally.

n“I’ll forge another one for Little Fox.”

nWhen Klein made the second gas mask, he chose the target to be the little fox.

nAfter using the same materials, the second mask appeared.

nThe two gas masks had different styles.

nThe one for the Little Fox was more protruding, like a dog muzzle.

n“Little Fox, give it a try.”

nKlein squatted down and put it on Little Fox.

nLittle Fox widened her eyes.

n“Can you breathe?” Klein asked.

nLittle Fox nodded.

n“It’s quite strong. Don’t take it off later.”

nKlein reminded her and took out the shovel.

nBefore digging, he checked the prompts as usual.

nDig down. You will be enveloped by the poisonous miasma. It won’t cause any harm to you. You will be able to find a Copper Treasure Chest and some resources.

nAfter Klein confirmed it, he began digging down.

nThe tunnel continued to extend downwards.

nLittle Fox squatted on Klein’s shoulder.

nShe wanted to help with the digging.

nHowever, her efficiency was far inferior to a shovel, and it was easy to be a hindrance.

nAbout twenty-five meters down, a black membrane appeared.

nKlein directly jumped down.

nHis body fell rapidly.

nIn midair, the floating propeller at Klein’s waist spewed out gas.

nSuspended in midair, he had already noticed the differences in this cavern.

nIn the air, there was a lot of grayish-white gas.

nThis was the miasma!
