Taking out a protein bar and biting it in his mouth, Yu Hong took off his shirt and began to exercise advanced physical training methods again.

After practicing for an hour, he began to find a hammer, found a place to squat down in the corner of the cave, and began to grind the powder hard.

He had already smashed a small piece of primitive pyroxene before, and now his main task was to grind it fine enough.

‘If the effect of dispelling shadows is composed of pyroxene and rune patterns, then I can directly use pyroxene powder to outline the rune patterns, and it will definitely be effective!’

While Yu Hong was polishing, he kept thinking about whether there were other better ways.

After about half an hour, the pyroxene powder was polished.

He added a little toner, poured it into a wooden bowl, added water, stirred, and it became a standard graphite juice.

After succeeding, Yu Hong looked out the window and saw that the sky was getting dark again.

‘Why do you feel like it’s getting dark faster and faster?’ He frowned slightly. He walked forward and pulled up the inspection window baffle.

Ever since he was frightened by a mysterious shadow, he never opened the flap again while sleeping.

Pulling up the flapper, he did not light the fireplace this time, but lit a candle and placed it on the wooden bench.

Then I used wooden strips dipped in axene graphite to carefully draw large axene runes on the stone wall on the side of the fireplace.

The stone wall was not flat, so he used chisels and hammers in advance to carve a large pyroxene rune the size of a basin on the wall.

Because he has already mastered it in other places, it is not difficult for Hong to carve rune patterns on the wall.

After all, the requirements are not high, just a rough fit, and it is large enough. Compared with drawing on small pyroxene, the difficulty is much lower.

Yu Hong carefully wiped off the fine dust on the wall, and then filled the large axene rune lines on the wall with graphite bit by bit.

The lines are very thin and don't cost much graphite.

In about ten minutes, the entire wall's rune stone carvings were completed.

Yu Hong took a step back and admired his masterpiece.

Boom, boom, boom.

Suddenly there was a rhythmic knock on the door.

"Is there anyone?" A strange woman's voice came from outside, "It's getting dark outside, can you let me go in and hide?"

"I heard a noise! ​​Is there someone inside?"

The voice outside continued.

Yu Hong's expression remained unchanged, as if he hadn't heard anything. He glanced at the door and saw that the large pyroxene behind the door was slowly but firmly changing color from top to bottom.

He exhaled, pulled up the stool, sat behind the door, and leaned against the side wall, waiting and watching quietly.

Boom, boom, boom.

The knocking on the door continued.

once.

twice.

three times.

Finally, everything became quiet again.

The large pyroxene behind the door has lost one-third.

Yu Hong quickly took it off and replaced it with a filled one.

Conveniently, he used the black seal to charge the great pyroxene. He stood up, returned to the sleeping bag again, and lay down on his back to rest.

The part of the pyroxene consumed determines the length of recovery time.

This time the shadow knocking on the door is not strong, and it only takes two hours to fill up.

Yu Hong put his hands on the back of his head and slept next to the candle with his head raised.

The biggest advantage of candles over fireplaces is that there is no need to add firewood.

And the light of the atomic lamp, according to what Jenny told him, cannot drive away the black bloodworms.

Only an open flame will do.

"Fortunately, the purpose of buying the atomic lamp is just to try out what it will look like after strengthening. If it can directly strengthen the energy reactor or something like that," he began to fantasize.

As time went by, he had become accustomed to living in this dangerous forest.

I am used to falling asleep in such a state where I may encounter danger at any time.

Boom, boom, boom.

Late at night, candlelight flickers.

A knock on the door woke Yu Hong from his sleep.

He glanced at the door panel, and saw that it was still dark outside. He knew it was another shadow, so he wiped the sweat from his forehead, stood up, picked up a small pot of boiling water, and took large gulps to replenish water.

After drinking the water, he stood up and ignored the knock on the door, and came to the graphite runes he had drawn during the day.

The washbasin-sized stone carvings with runes had already dried.

On the ground below lies the recovered large pyroxene, which has also been replenished by the black seal and restored to its original state.

Yu Hong ignored the big pyroxene, but stretched out his hand and gently pressed it on the big rune pattern on the wall.

This is his attempt. If successful, the utilization rate of pyroxene will be much higher than before.
Chapter completed!
