"This is already the fifth ninth-rank Heavenly God-level monster. We've already killed more than twenty eighth-rank and seventh-rank monsters, but none of them had that green energy. Could it be that the Minotaur Giant that Phaser killed just happened to have that green energy in its body? "

Gu Ding frowned slightly. Ever since Phaser killed the Minotaur Giant and obtained the green energy, Gu Ding and the others had been experimenting on various monsters, but the results were not satisfactory. None of the monsters that were slaughtered had that green energy in their bodies.

"No wonder Mr. Mo didn't mention this to us. I think those who came before have never encountered a monster with that green energy in its body." Biggie nodded.

"Why don't we try a tenth-rank monster!" Mi Ko suggested after a moment of silence.

"Let's try again. If it still doesn't work, we'll have to think of another way to seek enlightenment," Neptune said as he projected the map again and found the nearest tenth-rank monster. "Gu Ding or Biggie will probably have to do it for the tenth-rank monster."

The group soon arrived at the territory of the tenth-rank monster.

The monster looked very strange. Its entire body was covered in a layer of green bark-like skin. Its head was like a leaf that was folded vertically, and it had no facial features at all. Its two long arms hung low near its ankles.

However, when Gu Ding and the others appeared, the "folded leaf" on its head opened slightly. Through the gap, Gu Ding and the others found that it was completely dark inside.

"I'll do this battle!" Biggie volunteered. Seeing how strong the opponents that Ayesha and Phaser had fought were, Biggie had been itching for a long time. The eighth-rank and ninth-rank monsters that they had slaughtered previously were not challenging at all. The strange-looking monster in front of them made Biggie feel a little threatened.

Gu Ding had no doubts about Biggie's strength, so when Biggie volunteered, Gu Ding only nodded slightly. "Go, don't be careless!"

Biggie stepped into the void and dashed toward the monster with tree bark.

The monster with the tree bark seemed to have sensed that the newcomer was not friendly. It stretched out its hand and green lines flowed on its arm, turning into countless green plant branches that flew toward Biggie like an inescapable net.

Biggie unsheathed his sword and flipped his body. A black circular line rippled out in all directions like a wave, slicing all the branches in its path in half.

However, the broken branches quickly regenerated and continued to wrap around Biggie.

Biggie slashed with his saber again and again, leaving a trail of afterimages in the void. He was always able to find a chance of survival in the tight encirclement.

After a series of fruitless attempts, the tree-bark monster realized how difficult it was to deal with Biggie, so it gave up on its previous ineffective attacks. The tiny, net-like vines began to twist and intertwine, turning into a gigantic hand that was tens of thousands of meters in size, grabbing at Biggie.

Biggie let out a low growl, and an Emperor's projection that was hundreds of thousands of meters tall appeared in the sky. His entire body was covered in golden armor, and golden divine flames rose brilliantly. That illusory figure condensed to the point where it seemed solid, and it descended with endless pressure.

Biggie stood with his sword in front of him, and the golden Emperor raised its hand. Both of them slashed at the giant hand at the same time.

The entire void trembled under the attack, and it looked like it was about to collapse.

Gu Ding's eyes were fixed on Biggie's attack, and he could not help but mutter, "Sword Dao Deity Level … Biggie is only one step away from evolving his Sword Dao Realm into a Rule …"

"Biggie's talent in Sword Dao is indeed unparalleled. I'm afraid that even in the Main Plane, he would be a top-notch existence. Coupled with his Sword Heart divine power, he is simply a natural-born swordsman, "Neptune could not help but exclaim.

On the battlefield, the outcome of the battle was soon determined.

Biggie's sword gleam directly penetrated the giant hand's defense, and the giant hand's five fingers were cut off. After the sword gleam passed through the giant hand, the force of the sword did not diminish, and it directly cut through the tree bark monster's waist. Then, it pierced through the monster's waist, bringing with it a spray of blue blood.

The tree bark monster did not expect Biggie's attack to be so terrifying. It was killed on the spot before it could even put up a second wave of defense.

The tree bark monster's corpse quickly dissipated, and the remaining green energy quickly surged into Biggie's body as if it had a consciousness. Moreover, the green energy this time was several times more than what Phaser had absorbed before.

Biggie immediately sat down cross-legged. The Emperor projection above his head did not dissipate, but instead began to solidify.

Seeing such a strange scene, Gu Ding and the others spontaneously took up the responsibility of guarding.

"I now suspect that this green energy did not appear randomly, and that it only exists in the bodies of tenth-rank monsters," Neptune voiced his speculation.

"We can continue to verify it later. If this green energy appears in the tenth-rank monsters that we've killed one after another, then your speculation should be correct, Neptune." Mi Ke Er still felt that they should continue to verify it.

"This speculation is also possible because the previous participants who came in were at most low-rank Heavenly Gods, and very few of them were middle-rank. They did not have enough strength to kill a tenth-rank monster. That's probably why Mr. Mo didn't mention this to us. "Gu Ding nodded.

Biggie's aura skyrocketed as he sat cross-legged. Even his cultivation level had increased to tenth-rank True God, and he could break through at any time.

The martial arts realm in his body continued to rise, from the initial Minor Achievement of Heavenly Person to the great achievement, all the way to the complete stage, and still did not stop there.

Above his head, the virtual shadow of the Emperor projection gradually solidified. All of a sudden, Rule Sigil began to wrap around the Emperor projection, and the Rule Sigil became more and more complex and active.

Gu Ding and the others stopped talking and held their breaths as they watched the scene unfold.

"It's a Lord's Rule Sigil …" Gu Ding was shocked. Biggie had taken this step ahead of him after all.

Biggie sat cross-legged for three days and three nights.

Not only did his Sword Dao realm transform into a rule, but even his cultivation level had successfully broken through to heavenly god-level. The Heavenly God's aura was almost unconcealable as it spread out in all directions, carrying the endless power of the Sword Dao Rule, suppressing the countless monsters around him.

The monsters that felt this aura could not help but tremble, and they hid in their caves, not daring to come out to look for food.

The Emperor's Projection above Biggie's head suddenly moved as well. It lowered its head as if it had come to life. Its cold eyes swept across Gu Ding and the others before finally fixing on Biggie. It paused on Biggie for a moment before slowly dispersing.

The Nomological God Chains that were wrapped around the Emperor's projection also surged toward Biggie and entered his body.

After a long time, Biggie finally opened his eyes slowly …
