First of all, there was a prerequisite to using elemental magic to attack.

The surroundings must have those elements, and they had to be of a certain quality.

Whether it was water-elemental or wind-elemental spells, they were easy to deal with. After all, they were materials that could exist anywhere and anytime.

But it was different for wood-type spells.

And the forest that Klein was currently in didn’t lack trees. How could he not use wood-type spells easily?

Klein waved his hands and gathered the countless trees around him, as though he was a god commanding an army.

Then, a tall wooden wall instantly rose from the ground. The loud rumble made one’s scalp tingle.

James even felt his ears ringing.

The tall wall that rose from the ground seemed to have no boundaries. It continued to extend upwards and left and right, as though it was about to fill the entire space!

Klein could even hear the humming sounds of groups of Red Killers being blocked outside the tall wall. It was as though they were trying to think of a way to break through the barrier.

The Red Killers had very strong gnawing abilities. These wooden products were very easy for them to break through.

If it was an ordinary wooden wall, they would be able to drill a large hole very quickly.

Unfortunately, the wall in front of them wasn’t an ordinary wooden wall.

The wall constantly absorbed the surrounding wood elements for its own use. It could be said to be inexhaustible.

Not only could the wall extend indefinitely, but its thickness was also self-repairing,

Even the Red Killers, with all their strength, were unable to break through the thick wall!

James widened his eyes in shock. He didn’t expect Klein’s wood magic to be this powerful. He had never used it in such a difficult situation before?

With the huge barrier in front of them, it seemed like the disgusting Red Killers wouldn’t be able to charge over. The two of them finally relaxed.

Klein retracted his hands and patted his chest.

The magic he had just used had indeed exhausted him greatly. He was already feeling a little short of breath.

“Klein, how are you? Are you alright?”

Klein waved his hand. “It’s alright. It’s just that I’m using up some of my stamina…”

Furthermore, this magic defense was constantly growing and strengthening, constantly absorbing the energy in Klein’s body.

At that moment, James placed his hands on Klein’s shoulders, sending the inherent energy in his body over.

Klein’s fatigue gradually disappeared.

Since the crisis in front of them had gradually disappeared, the two of them decided to search the area.

If there were no other resources to plunder, they would leave.

After all, the purpose of their trip was to rescue the little girl, so it was not good for them to stay here for long.

At this time, James realized that the space was bigger than he had imagined, and he could not see the end of it.

The hasty escape just now had caused the two of them to lose their original direction. It seemed that they could only replan their route now.

Seeing that they had lost their direction, James took out a treasure that could tell the direction from his clothes.

It was a compass that paid attention to unique magic and could point them in the right direction.

Even if they were in a place where there was no reference, they could basically find the correct path according to the compass’s direction.

After some identification, James pointed southeast.

“It should be that place. If we follow the southeast direction, we can basically find our way out!”

Suddenly, Klein smelled a very strange smell. The huge fragrance was mixed with a hint of blood.

Klein frowned slightly. He felt that the smell was very familiar, as though he had smelled it somewhere before.

He stopped in his tracks and used his nose to search for the smell.

James found it strange. He knew that Klein had sharp ears and eyes. His sense of smell, hearing, and sight were all quite brilliant.

He asked, “Did you discover something?”

Klein patted James on the shoulder. “Did you smell a particularly strange smell? This smell is difficult to describe with words. It’s very intoxicating.”

James sniffed carefully. “No, is it because it’s too far away? You can smell it, but I can’t?”

Klein searched in the direction of the smell and indeed found a few green plants that were emitting golden light in a patch of grass.

At that moment, James could faintly smell the smell and couldn’t help but sneeze.

“Damn, what smell is this? It smells a little fragrant, but it has a strong fishy smell. It looks like a salted fish by the sea?”

James gave a rather inaccurate description.

It looked like the grass was colorful and very beautiful, but the smell was indeed unbearable.

Klein squatted down to observe the unusual grasses up close.

Suddenly, his eyes lit up, and his guess was finally confirmed.

That’s right, this should be the legendary Houttuynia!

It turned out that Klein had never smelled the smell of this Houttuynia, but the smell was recorded in the system.

The system had a very big characteristic. Whether it was sound, smell, or images, as long as they existed, they would be imprinted in Klein’s mind.

That was why Klein felt that the smell was very familiar.

James blinked his eyes. “Houttuynia? Why does it sound so familiar?”

“Ah, I remember now. I remember that some time ago, there was a rich merchant in the black market who offered a bounty for this Houttuynia. He needed this kind of Houttuynia and basically fired the high price of a hundred magic gems. At that time, the entire black market was in an uproar!”

This Houttuynia grass was actually not worth much because it didn’t have much use.

What Klein could think of was that it could be used as medicine and satisfy some people’s strange taste fetishes. They could eat it as food, but he didn’t know anything else.

The rich merchant definitely had his own use for paying such a high price for this Houttuynia grass, and it was difficult for him to say it out loud.

However, a hundred grams of magic gems was indeed a very tempting price!

James’s eyes lit up. “That’s right. This item is very rare. I’m afraid that we can only find a few in this mysterious space. If we take this Houttuynia grass back, we can exchange it for a hundred magic gems on the black market. Klein, we’re going to be rich!”

The so-called magic gems were very different from the synthetic gems they had previously obtained.

If synthetic gems were used to forge and upgrade weapons, then these magic gems possessed great power.

On one hand, they could be used for attack and defense, and on the other hand, they could be used as supplementary items to raise everyone’s magic level.

For example, Klein already had a tier 9 spell. If he wanted to raise it to tier 10, he would need a lot of materials to support it.

Magic gems were one of the most important things.

Klein gave James a thumbs up.
