[System notification: 1. Cured Meat + 70ml of water completed transaction. Wind Rune+1]

Klein had just logged out of the chat channel when the transaction notification followed closely behind.

'I've gathered all of them!'

He was delighted as he opened the manufacturing page.

At the bottom of the manufacturing list, he could see the formula for the synthesis of runic crossbows.

[Perfect Runic Crossbow: Iron 9/2, Copper 11/2, Wind Rune 2/2]

[Crossbow Bolts: Iron 7/2]

[Select Perfect Runic Crossbow and Crossbow Bolts.]

[Confirm forging!]

[System notification: Iron-4, Copper-2, Wind Rune-2]

[System notification: Perfect Runic Crossbow has been successfully forged.]

Klein's left hand had a crossbow with a compact and exquisite structure, and his right hand had five crossbow bolts carved out of a mold.

Long-range weapon in hand!

The runic crossbow wasn't heavy.

It was about a foot in length.

There was no bowstring, and a trigger at the bottom.

The body of the crossbow was gray and had many complicated patterns.

There were wind icons on both sides.

Behind it, there was an ammunition slot.

There were a total of five openings at the back of the crossbow, which meant that five bolts could be loaded at once.

The bolts were palm-long.

Each of the arrowheads was sharp.

[Perfect Runic Crossbow: A runic combat device. It has two firing modes, single-shot and multiple-shot. The bolts can easily pierce through iron plates, and the speed of the bolts is as fast as the wind.]

Two firing modes?

Klein looked at the runic crossbow and discovered that there was a small button on the handle.

His thumb could reach it.

He pressed it, and a crisp sound could be heard.

Klein inserted all five crossbow bolts.

He aimed them at the earth wall and pulled the trigger.

There was no movement.

[System notification: Additional soul required.]

"...As expected."

Klein finally understood.

As long as it was a runic device, fuel was essential.

He thought for a moment before saying, "It would be great if I could add wood. The water condenser can be activated with wood."

Klein had two souls.

One was a Yellow Sand Octopus soul, and the other was a Single-Horned Sand Hound.

"Add a soul."

As soon as Klein said that, a ball of light entered the runic crossbow.

[System Notification: Soul-1]

The runic crossbow vibrated gently.

The complicated patterns on the surface lit up one by one.

[Perfect Runic Crossbow: 100/100]

The number represented the number of times it could be fired.

A soul could be fired 100 times, and the multiple-shot mode counted as one shot.

"Give it a try?"

Klein drew the runic crossbow with one hand and aimed it at the earth wall again.

He pulled the trigger.

Shoo!

Five crossbow bolts were fired in unison.

They were as fast as the wind, and they disappeared in the blink of an eye.

Poof, poof, poof...

They all plunged into the earth wall and disappeared without a trace.

"They're a little fast, but they're powerful enough!"

Klein quickly approached the earth wall.

There were five holes on the wall.

They weren't arranged in a row, but intersected.

"I wonder how deep it is?"

Klein took out his shovel.

The number of times he had left to dig a tunnel was none but didn't mean that he couldn't dig. It was just that no matter how he dug, he was unable to enter the next catacomb.

He only used the shovel once and found the crossbow bolt.

Klein reloaded the crossbow bolt and returned to its previous position.

Shoo!

The speed of a single crossbow bolt was even faster, at least three times faster than before.

Klein dug again.

The first time, he didn't manage to dig it out.

The second time, he managed to dig it out!

Its power was more than doubled.

"Let's try again."

Klein needed to be familiar with the runic crossbow.

From its power, to its range, trajectory, and the feeling of shooting.

As for the number of times he could fire a crossbow, he could completely afford it.

A hundred shots were enough for him to save dozens of times.

Furthermore, he had another soul.

With the runic crossbow and Little Fox, it wasn't difficult to kill a crypt creature.

Poof, poof, poof!

He shot again and again, digging again and again.

Klein had a methodical way of training.

After every shot, he would either adjust his posture slightly or stop to think for a few seconds.

With constant adjustments, his proficiency increased.

After firing more than forty times in a row, Klein could shoot instantly. Without aiming, there was a seventy to eighty percent chance of hitting the target.

Apart from that, he could also quickly reload and simulate shooting.

Klein could already quickly reload a crossbow bolt and finish shooting in a second!

If he were to encounter an emergency, this move could save his life.

Klein thought for a moment before saying, "If I apply poison or anesthetic on the crossbow bolts, I'll gain an additional boost in battle."

Klein muttered to himself.

The runic crossbow's remaining firing times were 55.

Klein forged two more sets of crossbow bolts, using a total of four iron blocks.

'With the crossbow bolts, I'll pick a cave with crypt creatures tomorrow.'

Klein put away the runic crossbow and looked at the mud wall on his left.

During the day, the left side of the wall had a notification:

[Dig to the left. There are two copper treasure chests and rich resources. Unfortunately, there are two Rock Armor Crocodiles guarding them. Although they move slowly, they have a hard outer skin. The fox can't break through the defense, and you, a weakling, can't do anything about it.]

[Dig to the left. There are two copper treasure chests and rich resources. Unfortunately, there are two Rock Armor Crocodiles guarding them. Although they move slowly, they have a hard outer skin. It's best if an arrow hits their head. Otherwise, you'll suffer.]

If there were no runes, Klein planned on digging left.

There were resources and crypt creatures in the catacombs there.

Little Fox could deal with one.

"Two of them. Their movements are slow..."

"As long as I make a plan, it won't be difficult to destroy them one by one."

Klein already had a plan in mind.

Tomorrow, he would have Little Fox stall one while he dealt with the other.
