The Golden Firestorm Saber!

Holding it in his hand, Klein felt that the weight was about the same as before.

But for some reason, he felt at ease.

"Let's see how powerful it is."

Klein went around the cracked ground and walked to an empty spot.

He aimed at a wall that had yet to be affected.

He gently brandished his Firestorm Saber.

He had yet to use flames.

It was just a slash.

A half-meter-deep crack instantly appeared on the wall.

"Not bad."

Klein nodded in satisfaction. The power was much stronger than before.

Previously, Klein could only do so much with his fire ability.

He was slightly attached to the flame.

He slashed again.

The entire wall was cut in half.

It collapsed with a loud bang.

"What an exaggerated strength."

Klein looked at the Golden Firestorm Saber in his hand once again.

The power of this saber had undoubtedly received a huge boost.

It would be much easier to deal with other crypt creatures in the future.

'As expected of the armor of the Golden Sand Dragon. It's indeed terrifyingly hard.'

Klein retracted the Golden Firestorm Saber.

The Little Fox and Little Wind were dumbfounded.

However, they quickly reacted.

They ran over and surrounded Klein intimately.

They seemed to be celebrating the great increase in their master's strength.

Klein lovingly stroked their heads.

He opened the world channel.

Trading Mall.

Klein habitually browsed through private messages backstage.

Every day, there would be many people sending private messages to Klein.

Some would ask all sorts of questions, some would simply cause trouble, and some would express all sorts of love to Klein, begging him to save them and give them some food.

In short, there were all sorts of people.

Klein wasn't interested in any of these things. He would just glance at them and they would immediately flash past him.

However, among the many private messages, there was one type that Klein would pay special attention to.

It was private transaction messages.

These people would often bring up some things to make a deal with Klein.

Although most of them were about things that Klein didn't like, occasionally, there would be some items that made Klein's eyes light up.

Klein would often check his private messages in order to occasionally catch a good catch.

After a few minutes, a private message caught Klein's attention.

The person's name was Maka.

In the private message, he wished to trade 50 runes each with Klein.

This was no ordinary condition.

Although at this stage, runes were no longer rare, however, such a large number of runes and a rich variety of runes was still a considerable expenditure for Klein.

Since the other party had raised such a high condition, Klein wanted to see what the other party was willing to exchange for him.

"I have all the things you mentioned, but I want to see what you plan to exchange with me," Klein said directly.

"Mr. Klein, I plan to use this Rapid Growth Potion to exchange with you."

"Rapid Growth Potion?"

Klein asked out of curiosity.

"That's right. This potion can allow animals and plants to grow rapidly without any side effects."

"How many times can it be used?"

"Depending on the object you use, the plant can be used three times, and on the animal, it can be used twice."

"Let me think about it."

"Alright, Mr. Klein. I'll be waiting for your reply anytime."

Klein left the chat channel and began to think seriously based on his current situation.

The first thing he thought of was the Water Elemental Grass.

He had just planted this grass seed.

He didn't know how long it would normally take for it to bloom and bear fruit.

Klein took out a metal ball, silently recited an incantation, and the runic base unfolded.

"Alu, Lulu, when will this Water Elemental Grass bloom and bear fruit?"

Klein walked into the plant shed and asked when he saw the two Flower Spirits who were carefully tending to the plants.

"Mr. Klein, you're back! Did you say Water Elemental Grass? Normally, it would take at least three months."

"But under our care, one month will do."

Lulu and Alu came up to Klein and replied.

"A month? That's a long time," Klein muttered to himself.

"Have you heard of something called the Rapid Growth Potion?" Klein asked the two flower fairies.

Alu nodded and said, "I've heard of it! I've read about this Rapid Growth Potion in our family's books. It's something as rare as the Water Element Grass."

"Mr. Klein has obtained the Rapid Growth Potion?"

"There's someone who wants to trade with me, but the offer isn't cheap. I'm considering it," Klein said with a smile.

"Then, under the circumstances that Mr. Klein can afford, we suggest that you trade with him."

"Yes, yes. Trust us. We won't lie to you."

The two little fellows looked at Klein with their adorable big eyes and spoke seriously.

"Alright, then I'll listen to you. I originally intended to make a trade with him, but I wanted to ask you before the trade. Since you've said so, then I'll make a trade with him."

With that said, Klein left the runic base and put it away.

He entered the trade channel again.

"Mr. Klein, have you thought about it? Actually, there are others who want my Rapid Growth Potion, but they lack some runes, so I didn't agree," Maka said.

"Hehe, then you've come to the right person. I have everything you want. I've thought it through. Let's directly trade."

"Alright, Mr. Klein."

When Maka heard that Klein had agreed to the trade, he was extremely happy.

Soon, the trade was successfully completed.

[System notification: Fire Rune-50]

[System notification: Wind Rune-50]

[System notification: Water Rune-50]

...

[System notification: Rapid Growth Potion+1]

It was a colorless and transparent liquid that looked similar to ordinary water.

Klein opened the bottle cap and took a whiff. There was a faint fragrance.

Klein quickly returned to the runic base.

"Leave it to us, Mr. Klein."

The two Flower Spirits very carefully took the small bottle in Klein's hand that contained the Rapid Growth Potion.

They poured it into the soil where the Water Elemental Grass seed was buried.

Klein, Little Wind, Little Fox, and the two Flower Spirits all focused their gazes on the small piece of soil.

They were anxiously waiting to see if there would be any changes.

A few minutes passed.

From the originally flat soil, a green sprout suddenly appeared.

It was the green sprout of the Water Elemental Grass!

"According to this, in about a day, this Water Elemental Grass will be able to bloom and bear fruit," Alu said excitedly.

"Congratulations, Mr. Klein. I'm also looking forward to what the Water Element Grass looks like. I've only heard of it in books, but I've never seen it with my own eyes. This is a rare opportunity," Lulu also said with a look of anticipation.

Klein smiled and nodded. After a while, he left with the Little Wind and Little Fox.

He planned to use this time to enter the next catacomb.

There were three more chances to go to the catacombs today.

The seventy-first catacomb!
