The biggest feature of Guiying.

Previously, he opened the viewing window for ventilation, allowing the outside air to flow in through the steel mesh.

I didn’t expect to be discovered by Guiying so quickly.

"It's only dusk and it's not dark yet, and the shadow activity has started again."

Standing up, he carefully stepped forward, stretched out his hand, and pulled up the inspection window baffle.

Swish.

The light from the window disappeared, leaving the cave in darkness.

Yu Hong switched to the ventilation hole on the other side to ventilate. Although it was slower, at least it would not be so scary.

Who knows how long that mysterious shadow had been watching him while he was sleeping.

After doing this, with a little light seeping through the ventilation holes, he checked the reinforced pyroxene placed behind the door.

The strengthened pyroxene has reached half its volume and has changed from jade to pale stone gray.

Yu Hong was also horrified when he saw it.

'Fortunately, I have the enhanced pyroxene, otherwise I would have died without even knowing how I fell asleep.'

Sighing, he smelled a faint smell of fresh water in the cave and knew that it would become moldy if it was not dried.

The only hope now is to see what will happen after the furnace is strengthened.

At this time, there is still more than ten minutes left in the countdown on the stove.

Yu Hong simply sat down on the spot, took a dried mushroom, and ate it bit by bit.

He stopped looking at the door and stared at the stove.

More than ten minutes passed quickly.

The furnace figures will be finished soon.

Yu Hong's nerves also became slightly nervous, because this strengthening at this time may be related to his subsequent plans.

laugh.

At this moment, the number on the stove suddenly disappeared, and the entire stove and the smoke pipe became blurred.

After the blurry state lasts for one second, everything becomes clear again.

At the same time, a brand new furnace appeared in front of Yu Hong.

"!!? This is it." The moment Yu Hong saw the new stove, his eyes widened.

Because the thing in front of him has completely exceeded his expectations.

What appeared in front of him was a fireplace that was completely integrated into the cave rock wall.

This fireplace seems to be completely integrated into the rock wall, with itself and the chimney completely buried deep in the stone.

And the most important thing is not this. Rather, the shell material of this stove is completely transparent!!

They are all transparent synthetic materials similar to glass crystal!!

Yu Hong took a step forward, stretched out his hand and gently tapped the outer edge of the stove.

Bang bang!

Two muffled sounds, very hard.

"It's amazing. It's really heating and lighting." Yu Hong was speechless.

Stoves are very useful for heating, and if they are made transparent, lighting will naturally be provided.

This enhancement is simply genius!

He observed the new furnace for a while, until the light outside completely dimmed and a faint rustling sound could be heard.

He quickly took out the matches and lit the candles.

The strengthened candle is windproof and can collect oil fumes on its own, which is quite good.

Putting the candle on the stool, Yu Hong quickly started stuffing firewood and kindling materials into the stove.

The igniting material was the wood flowers he had left behind before, which are ultra-fine wood chips cut from wood. They are very rolled and easy to ignite.

Pair it with some dried hay leaves.

Kaka

Soon, a dark red flame slowly lit up in the fireplace.

The flames gradually grew larger over time, and thick gray smoke floated from above, poured into the flue, and floated outside without leaving any residue inside the cave.

The flame slowly became brighter and brighter, growing larger and larger.

Gradually, the firelight in the transparent fireplace became brighter than the candle.

After more than ten minutes, as the fireplace stabilized, Yu Hong added thicker pieces of firewood and blew out the candles in one go.

'Finally, it's done!'

He sat down from the squatting position on the log stool and looked at the burning fireplace with satisfaction.

The warm heat waves seeped out from the transparent shell of the fireplace.

This material actually conducts heat very well.

As the heat wave increases, the coldness of the cave is gradually dispelled, replaced by relaxation and warmth.

For a time, the entire cave was as warm as spring, bright and safe.
Chapter completed!
