The Ancestral Dragon also sensed the existence of the Ten Thousand Poisons Pearl, and was immediately shocked and angry, and reached for the pearl with his huge dragon claws.
But Shen Luo had already formed the last hand seal with both hands, and the Big Dipper formation was fully activated.
The Seven-Star Sword shone brightly, forming a strange array around it, with the Big Dipper in the center and another 365 stars arranged around it.
An extremely sharp sword energy burst out, filling the entire void. It was more than ten times stronger than before, and even contained a murderous intent to annihilate everything.
The black and green light domain was pierced by thousands of holes due to the sword energy, and it exploded and collapsed completely.
Shen Luo was slightly stunned. The Big Dipper Sword Formation was the last variation of the Seven Killing Sword Formation. He did not expect it to be so powerful. The formation had just been formed and had not yet been activated, but it had already broken the black-green light domain.
The body of the Ancestral Dragon appeared, and its huge body was covered with criss-crossing scars. Blood gushed out, dyeing half of its body red.
The dragon was very powerful, and even after suffering such a severe blow, it was not fatal. Black gas surged on its body, and the wound healed quickly again.
Shen Luo secretly admired him, but did not allow him to heal his wounds, and the sword moves in his hand changed.
"Seven stars gather together!"
The seven giant swords spun around, connected head to tail, and instantly formed a huge sword circle that wrapped around Zulong's body.
Zulong's face showed a look of fear and he was about to make a last-ditch effort, but it was too late.
The sword circle spun with a loud bang, and the nearby void was shattered. The body of the Ancestral Dragon exploded and turned into countless blood rains that splashed in all directions, leaving not an inch intact.
Shen Luo did not dare to relax. He made hand gestures with his five fingers one after another. Balls of heavenly fire appeared in the sword formation space and instantly turned into a sea of fire, reducing the bloody remains of the Ancestral Dragon to ashes.
"I didn't expect the Pure Yang Seven Killing Sword Formation to be so powerful. It's a world of difference compared to before." Huo Lingzi's voice sounded again.
"Last time, I only used sword energy to scare off Mi Su and his group, and I didn't even condense the sword into shape. This time, I want to kill Zulong, so I naturally can't hide my shortcomings anymore." Shen Luo killed Zulong in one fell swoop, feeling happy in his heart, and explained with a laugh.
"Shen Luo, your strength is becoming increasingly difficult for me to fathom." Huo Lingzi sighed.
"Thank you for the compliment, Brother Huo. Have you completed the soul search? It was very quick this time. What did you gain?" Shen Luo asked after a faint smile.
As he spoke, he made a gesture and emitted a golden light, which then rolled over an object from somewhere in the sword formation space. It was the Ten Thousand Poisons Primordial Pearl.
"The spiritual power contained in those two demon heads is very scarce. Mr. Zi's spiritual body may have been killed by you. What I found is very little, not much valuable. I am really ashamed. But from the memory of that residual soul, I saw some fragments that Mr. Zi seemed to be proficient in the magic of the heart demon." Huo Lingzi said a little embarrassedly.
"The Heart Demon Technique!" Shen Luo's face suddenly changed color when he heard this. He was silent for a moment and then suddenly looked around, with a crystal light shining from between his eyebrows.
In mid-air, Nie Caizhu saw Shen Luo kill Zulong in no time, and she couldn't help but feel surprised and happy.
Although she had long known that Shen Luo was very powerful, she was still surprised every time he made a move.
"Cousin, your strength has improved again. It seems that you are not far from the realm of Heavenly Venerate..." Nie Caizhu flew down.
Shen Luo suddenly flew out, lightning flashed on his body, and his figure disappeared instantly. The next moment, he appeared dozens of feet away, grabbing with his five fingers as fast as lightning.
