I built a floating city in the game.

"Phew, finally finished."

Mo Bai looked at the spell model that had already taken shape in front of him.

A spell model consisting of up to twenty-seven spell nodes and five spell structures.

"Stone Skin Technique!"

After trying it out, Mo Bai gave the spell model a name, while Yang Hao, whose eyes were slightly red, was also very excited.

He absorbed the knowledge and ideas that Mo Bai had just revealed as quickly as a dry sponge.

He also contributed to the successful derivation of this spell model.

As soon as Mo Bai had a thought, the spell model landed directly on Zhou Lin, who was watching the commotion from the side.

"Buzz!"

A yellow light flashed across Zhou Lin's body, followed by a layer of dark yellow soil covering his skin.

Curious, he moved slightly, feeling a bit sluggish, and then saw Mo Bai wield a long sword and slash down instantly.

"Click!"

Zhou Lin raised his hand to block, and the long sword landed on his left arm. Upon closer inspection, there was only a shallow cut on it.

"Holy crap, awesome, and it doesn't hurt."

He was immediately shocked when he saw this.

"If I had this, I could go on a rampage through a crowd!"

"Yes, yes, it works well."

Mo Bai nodded in agreement, while Yang Hao watched the entire spellcasting process, pondering it carefully.

Suddenly, Mo Bai looked at Zhou Lin and spoke.

"Zhou Lin, are you... interested in doing an experiment?"

Perhaps this will give you a basic understanding of the extraordinary.

"Huh? What kind of experiment, extraordinary? Yes, yes, I want it, I want it."

Zhou Lin was slightly taken aback, then quickly nodded happily.

If someone else said it, he might think it was just a bluff.

Extraordinary beings can appear out of thin air, but if Mo Bai says this, then he will definitely believe it unconditionally.

"First of all, let me make it clear that I do not guarantee success or the consequences, but I will provide all the materials."

"Yes, absolutely."

Zhou Lin answered without hesitation, and then added a little more.

"Brother Mo, what risk? There's no opportunity in the world without risk."

It is possible to attempt the extraordinary in this situation where no player is extraordinary.

"If word got out, people would fight tooth and nail for it. Even if I fail, it's just a gamble on my part."

Mo Bai nodded upon hearing this, and immediately put down the Stone Skin spell model without saying anything more.

The Stone Skin Technique's extraordinary potion requires an earth elemental extraordinary crystal core, which he currently lacks.

However, he had two extraordinary crystal cores in his hand.

For the liquid extraction of various medicinal materials, there are professional tools that can maximize the utilization rate. However, if the requirement is only 50% usable, then it is not impossible to make some tools temporarily using stones and bamboo tubes.

As for its combat potential, Wind Blade can be used to cut through strong defenses when cast normally, and its spread release can create a wind wall to block ranged attacks. Further refinement allows it to be used for rapid movement and increased attack speed. Its combat potential is definitely not weaker than Stone Skin, except...

When Mo Bai thought of this wind blade technique, a voice seemed to echo in his mind.

"Hasage".

"If we fail, that's fine, but if we succeed, we'll definitely be very happy."

The corners of his mouth turned up slightly.

"Very happy."

Under his gaze, Zhou Lin couldn't help but scratch his head and subconsciously took two steps back.

A moment later, Zhou Lin began to collect and prepare various materials needed to process the herbs, while Mo Bai looked through his previous notes and conceived an experimental plan.

Yang Hao continued to experiment with the remaining fire element spell structures using exhaustive methods.

Before long, it got dark and then light again. As the sky darkened again, a series of strange, cawing laughs suddenly rang out from the forest, startling a flock of forest birds into flight.

In the forest, in the dim light of dusk, Mo Bai gazed at the huge shadow of the mountain to the south, a slight smile playing on his lips.

A moment later, the three left with all their belongings, leaving only a huge rock covered with magical structures in place as proof that they had been there.

Along the way, Mo Bai continued to teach Zhou Lin some adjustments to the use of the Wind Blade Technique, which he had developed in his spare time during his experiments.

It only requires minor adjustments to the spell model to use, which is very convenient.

At first, Mo Bai tried to explain the development principles to Zhou Lin so that he could try to develop it on his own.

However, he gave up after only a short while, and then I tried to explain the operating procedure to him.

After a moment, he decided to help him summarize some foolproof methods and easy approaches.

It must be said that Zhou Lin's fighting instincts and swordsmanship were definitely earned through his intelligence.

After memorizing these methods by rote, he didn't care at all even though his attributes had dropped from level five to level three due to his weakened state, and his face was full of joy!

Teaching Zhou Lin felt more tiring than conducting experiments for over twenty hours straight.

Freed from his predicament, Mo Bai looked up at the mountain peak that was now almost within reach, and the mountain stronghold at its summit.

The players' battle had just ended, but the catapults below the mountain were still hurling bags of fist-sized stones at the mountain stronghold on the mountaintop.

"Huh? Huh? A catapult?"

Mo Bai was stunned when he saw this thing. Then he saw many hand-held siege battering rams on the mountain road. They even had A-frame wooden roofs to block arrows, but they had been smashed by huge rocks rolling down from the top of the mountain.

"There are talented people everywhere here; they've even come up with catapults."

It seems that this Big Axe Gang's stronghold is located in the mountains, and the mountain roads are extremely difficult to navigate.

Wherever there is flat ground and a wide road, once the catapults are pushed over, and the battering rams and siege towers are pushed over, all that damn mountain stronghold will be leveled.

What wall could possibly stop such a trebuchet, practically a trebuchet?

Mo Bai couldn't help but mutter to himself, but then he looked up and saw faint sounds of battle coming from above.

"There should also be other players who climbed up from the side and then launched an attack together."

Mo Bai made a rough deduction and, seeing that it wasn't completely dark yet, immediately led Zhou Lin, who was walking with a brisk pace, and Yang Hao, whose eyes were bloodshot but who was still exhaustively listing the structure of the spell as they walked, away from the foot of the mountain.

After the sky had completely darkened, Mo Bai quietly arrived at the back of the cliff, where it was pitch black.

Climbing in the dark, Mo Bai made no sound at all, and every movement was incredibly precise, without the slightest waste.

As he approached the summit, his mental energy immediately detected a lit torch and two henchmen hidden beside the cliff, each holding a long pole.

Mo Bai waited a moment, and while they were talking, he reached up and touched the edge of the wall.

He immediately realized that the level of vigilance had increased, with sentries both visible and hidden everywhere, making it a heavily fortified area.

However, as a gang, they were destined to lack sufficient discipline.

Even the most stringent blockade is just a sieve without sufficient discipline, full of loopholes.

I randomly found a spot where a sentry was asleep and climbed over the wall.

However, he was suddenly stunned when he saw the corpses and bloodstains left inside.

"Huh? How come there's a corpse and bloodstains after a player dies?"
