The Heavenly Reversal Nine Swords is top-tier swordsmanship, ranging from simple to difficult, and each move becomes increasingly challenging. Lin Mo pondered the Third Form: Heaven and Earth Battle for two months, but had only grasped the basics.

"Let's try again, I refuse to believe I can't master this third form." Lin Mo's gaze was firm as he stared into the void.

With the Golden Trial approaching, he had to find a way to enhance his strength no matter what.

The aura of Heaven and Earth Battle is domineering, with much more impressive speed and power than the previous move. Lin Mo gripped the Xuanyuan Sword and circulated his Star Power in his Dantian according to the mental method of the third form, and his aura began to surge continuously.

"A hundredfold combat power amplitude!"

The Star Power within his Dantian radiated a dazzling brilliance, and the overflowing Star Power spread throughout his body.

"Heaven and Earth Battle..."

Lin Mo drew his sword and rose, as if the Star Power within him had been punctured like a balloon, the gathered Sword Intent also crumbled instantly.

"As expected, it's not possible yet, I still can't execute the third form." Lin Mo furrowed his sword eyebrows, a look of confusion on his face.

Swordsmanship executed with Space Laws is omnipresent, absorbing the power of heaven and earth, extremely domineering. Yet every time he wanted to execute it, he would falter at the final step, unable to sense that kind of Sword Intent.

"That's right, the mysterious black iron block." Lin Mo's eyes widened as a flash of inspiration passed through his mind. He immediately opened his Space Ring, took out two black iron blocks, and let them float before his eyes. Lin Mo never knew what these black iron plates were for, just felt they were fragments of some kind of Treasure. One block was obtained from Count Johnny, and the other from the elder of Hongmen.

He had no idea what these two mysterious black iron were, nor could he confirm their material. However, every time he used his Divine Thought to sense them, he could feel the wondrous Space Laws. Lin Mo's Qiankun Step was created through realizing some Space Laws from one of the blocks.

"Since the third form relies on understanding the Space Laws, I'll try it with these two mysterious black iron."

For the next month, Lin Mo's daily task was to use Divine Thought to probe the two black iron blocks, enhancing his understanding of space, then find time to practice his sword.

Day after day of training, a month passed in the blink of an eye.

Lin Mo severed the exploration of the black iron with his Divine Thought, suddenly opened his eyes, his gaze flashing with brilliance, "Haha, one more time, I won't believe I can't succeed!"

In the void, Lin Mo stood holding his sword.

"Five hundredfold combat power amplitude!"

The Star Power within him began to rotate, forming an ancient and mysterious pattern, his aura surged, causing the surrounding illusion beasts and demon beasts to flee into the dark in fright.

"Heaven and Earth Battle!"

Lin Mo gripped the sword hilt with both hands, suddenly slashing forward into the void. The world turned pale, darkness dissipated, leaving only the blinding white sword light. The heavens and earth seemed to have turned silver.

The power was overwhelmingly domineering, the sword light omnipresent, the whole world seemed on the brink of shattering. But just for a moment, darkness returned, Lin Mo's face turned pale, with a bitter smile at the corner of his lips: "The power of this third form is indeed extraordinary, I barely managed to execute it, and there's a backlash... Wanting to comprehend this third form within a month is indeed too greedy."

Inside the Prison Tower.

Lin Mo spent a month and could barely execute the third form, but it was just execution, not displaying even one percent of its power, with quite a backlash to his body.

"Mr. Lin, the Golden Secret Realm Trial is about to begin, the Guiding Envoy has sent a message, we need to gather at Kunlun Mountain within three days."

Just as Lin Mo was shaking his head in resignation, a distant Black Fog flew over, it was Zhen Yuanzi, respectfully speaking.

"Mmm, the time has come, I'm also eager to compete with the world's geniuses in the Golden Secret Realm." Lin Mo placed the Xuanyuan Sword on his back, his gaze gleamed with a sharp light.

"But before leaving, let's check the changes in the Blood Demon Vine."

With that, Lin Mo transformed into a streak of Flowing Light, flew towards the palace in the void, landing in the palace square.

Last time the Blood Demon Vine swallowed many Treasures, it had been in slumber, recently Lin Mo sensed the Blood Demon Vine beginning to awaken and transform... "Blood Demon Vine..." Lin Mo closed his eyes, feeling the Blood Demon Vine within him starting to awaken, its power climbing continuously, soon, eight arm-thick dark red vines flew out from his back, growing and stretching in the void, each vine eventually growing to nearly a hundred meters in length, their color turned even scarlet.

"Haha, the Blood Demon Vine has finally evolved to the Condensation Stage, I have an extra strength."

Witnessing the active Blood Demon Vine, a delighted smile appeared on Lin Mo's face: "Body Shield."

With Lin Mo uttering two words, the vines of the Blood Demon Vine began to twist and wriggle, the eight vines retracted, in an instant, wrapped Lin Mo entirely as if wearing a dark red battle suit.

The Blood Demon Vine, as a Life Class Magic Treasure, has effects of attack, binding, and defense. Although it doesn't surpass the Xuanyuan Sword or the Sealing Heaven Axis in individual aspects, it possesses more comprehensive capabilities.

"Congratulations Mr. Lin, with the Blood Demon Vine reaching the Condensation Stage, you have gained another trump card in the Golden Secret Realm Trial." Zhen Yuanzi floated in the air, speaking.

"Mmm." Lin Mo nodded, his thoughts moved, the Blood Demon Vine merged into his body, vanished, then he looked at Zhen Yuanzi and asked: "Zhen Yuanzi, there's something I've always wanted to ask you, what's the purpose of this Prison Tower? Why are there endless illusion beasts and fierce beasts?"

"This..."

Hearing Lin Mo's question, Zhen Yuanzi frowned tightly, then shook his head and said: "Ever since I joined the Nine Stars Sect, the Prison Tower has always been here, actually, I too don't know the origin of the Prison Tower."

"Oh, even you don't know." Lin Mo lightly furrowed his sword eyebrows, smiling: "Fine, after completing this Secret Realm Trial, I'll explore the secrets of the Prison Tower."

During his three months in the Prison Tower, Lin Mo also noticed some extraordinary aspects of the tower.

"Mmm, then I'll stay in the Prison Tower cultivating, waiting for Lin's victory." Zhen Yuanzi cupped his hands.

Lin Mo smiled slightly, his whole person transformed into a Flowing Light diving down.

Leaving the Prison Tower, breaking through the lake surface, Lin stood in the air.

Compared to the dark, oppressive, eerie atmosphere of the Prison Tower, the green mountains and clear waters outside instantly lifted one's spirits.

"Master."

"Master Lin."

"Master Lin."

Several people stood on the lake, precisely Yingzi, Zhuang Ziruo, Fang Tangjing, and Liang Yuan.

"Everyone is waiting for me here?" Lin Mo smiled and flew to stand before the group.

"The Golden Secret Realm Trial is ready to begin, we thought you might come out today." Fang Tangjing said.

"This time in the Secret Realm Trial, you're representing our Nine Continents Secret Realm, the Four Great Martial Arts Schools, the Martial Arts Alliance, you must succeed." Liang Yuan smiled and said.

Lin Mo said: "Mmm, no matter what, I'll do my best." Although the Golden Secret Realm Trial is a test for the Mystic Realm Sect to select disciples, it also relates to some competition between other forces. In this Secret Realm Trial, only Lin Mo represents the New Human, the Four Great Martial Arts Schools, and the Martial Alliance. If Lin Mo can achieve good results, then

the Four Great Martial Arts Schools and the Martial Alliance will also gain many hidden benefits.
