Thinking about this, Xiao Yi could only make up his mind. He once again summoned the Wind and Thunder Banner, which swelled with the wind. Even though he knew that the ink must be extremely corrosive, he still went up to meet it.

"Puff, puff, puff!" The overwhelming poisonous ink was blocked by the Wind and Thunder Banner, but it was still contaminated by it.

Nevertheless, he had gained precious time to save lives.

"Qiangwei, save people!" Xiao Yi shouted at Qiangwei behind him.

"Got it!" Although Qiangwei didn't expect to get involved in the fight against the demon, as a strong cultivator in the Middle-stage of Qi-refining, she saved more than a dozen civilian workers without any effort while Xiao Yi was entangling the demon.

With a shake of the whip, she wrapped around the group of workers. In an instant, they were transferred to the outside of the courtyard and stayed as safe as possible.

At this moment, the surface of the banner, which was originally covered in black lightning, was now covered with corrosion traces, making Xiao Yi feel pain in his heart. He realized again that he had underestimated the power of this demon. Although he had not yet stabilized its shape, it was, after all, a big demon in the Transformation Stage.

In a short while, the sound of the wind on the banner died down, and the raging lightning gradually became thinner. It seemed that the banner was going to be completely destroyed.

"Hahaha, incompetent humans, do you have any other tricks? Show me all of them. I'll make sure you die in peace," said the gigantic half-translucent worm body as it floated in mid-air. Eight tentacles that were about three meters long were flailing wildly in the air, causing the demon to laugh out loud in a highly arrogant manner.

Xiao Yi was at a disadvantage, but his expression did not change. Instead of retreating, he advanced and infused his True Energy into the nearly-destroyed Wind and Thunder Banner.

The Wind and Thunder Banner emitted a loud cracking sound. The Spiritual Force was violent, and the power of the wind and thunder, which had been gradually disappearing, became abundant again in an instant.

"Hey, hey, do you want to detonate the Wind and Thunder Banner with your True Energy to hurt me? Stupid human, you are too naive." Seeing Xiao Yi's action, the demon had nothing to fear. It sneered and shrank its body suddenly. It opened its huge mouth, and a stream of black Qi suddenly spurted out of its huge mouth.

The black energy was extremely strange and spread out extremely quickly. However, as it spread, it didn't seem to be thin at all. Instead, it became denser, covering the entire courtyard in the blink of an eye.

The demon's figure was immediately concealed within the black mist. Even with Xiao Yi's powerful Divine Awareness, he was still unable to see through the black mist. Xiao Yi knew that it must be a technique that the demon was proud of. It must have been cultivated to a remarkable level.

The next moment, Xiao Yi heard a muffled sound coming from the Wind and Thunder Banner.

Xiao Yi was shocked. He instantly realized that it was riding on the black mist and trying to tear the Wind and Thunder Banner directly with the strength of its tentacles.

"I didn't expect this thing to be so powerful." Xiao Yi immediately retrieved the Wind and Thunder Banner.

Who would have expected that at this moment when he was distracted, he would suddenly sense an extremely intense dangerous aura that had just appeared behind him?

"No!" Xiao Yi cried in a low voice, and his body immediately rushed forward reflexively. At the same time, the Seven Stars Sword Pills came out of his body and formed a sword net around him to protect him.

Sure enough, just as Xiao Yi's figure flashed, several muffled sounds of "bang bang" came from behind him. That was the sound of the tentacles of the evil demon and the Seven-star Sword Formation colliding.

The force was so strong that Xiao Yi knew that if it fell on him just now, even if he had a strong body, he would definitely end up with broken bones.

"D*mn it, this thing has so many tentacles and looks like a natural soft whip magic treasure. It sneak attacks from all directions, with the ability of the black mist to hide its body and it makes it invulnerable to swords and spears. It's extremely tricky." Xiao Yi was enveloped in the black mist, and his Divine Awareness could not completely penetrate it. He was still in a passive state and could not help but feel anxious.

He was trying to think of a way to deal with the evil demon when he realized that the black mist had suddenly become thinner on its own accord. The large figure of the demon finally appeared within Xiao Yi's Divine Awareness.

"Huh? This strange and troublesome black mist has actually paled by itself. Could it be that it has a limit? There is no need to be afraid." Xiao Yi could not help but rejoice in his heart when he saw that the black mist had become thinner.

However, when his Divine Awareness swept past the evil demon, he discovered that the evil demon was actually looking at him with a smile that was not a smile.

"Hmm? No, there's something strange about this." Xiao Yi's heart tightened but he was surprised to find that not far away from him were drops of dark-black water. Each drop was only the size of a grain of rice, but they were all over heaven and earth as they slowly gathered around him.

"This is bad. Not only does this demon possess a strong physical body, but its mind is also cunning. It spat out black mist and launched a sneak attack to paralyze me. Without a sound, I was actually trapped by it." Xiao Yi was suddenly on high alert.

"Hahaha, foolish human, have a taste of how powerful my Bone Eroding Poison Array is. Each drop of this Black Poison Pearl is strong enough to penetrate any magic treasure. It goes through your skin and goes straight to your marrow. There's so simple. I've placed forty-eight thousand of them here. You're already unable to escape. Hahaha, I can't wait to see how you've been corroded by all kinds of poison." The demon laughed strangely. As it spoke, its body's movements did not stop. With eight tentacles wildly shaking, it activated the forty-eight thousand Black Poison Pearls between heaven and earth. They were dense and dense as they rained down on Xiao Yi.

"What should I do? I am afraid that ordinary magic treasures can't resist these extremely corrosive Black Poison Pearls. I am afraid that even the Square Gourd can't resist it. Is it possible that I am going to use the magic talisman that Senior Li Shang gave me?" Xiao Yi was extremely annoyed in his heart. This time it could be said that he had underestimated the enemy.

At first, Xiao Yi thought that this demon only had a strong body, but he didn't know that this thing's magic was excellent. Besides, it was cunning, which put Xiao Yi in danger.

At this critical moment, Xiao Yi suddenly heard a somewhat weak voice from the empty space. He said, "Sect leader, I have come to help you!"

Hearing this voice, Xiao Yi's heart immediately went wild with joy.

It was none other than Duanmu Kurong's voice, who possessed the Sky-ghost Body.

In the early days, Duanmu said that he had to deal with some old affairs in the secular world, so Xiao Yi let him deal with them. He thought about the affairs in Jing City, so he asked Duanmu to come back. Unexpectedly, at this critical moment, he appeared.

Duanmu squirmed in the air and suddenly appeared in front of Xiao Yi. He still looked like a cute little girl, but his expression was withered. His delicate little face had lost its radiance at the moment.

Before Xiao Yi could say anything, Duanmu pulled Xiao Yi up and immediately flashed into the void. The next moment when they appeared, they were already outside the Bone Eroding Poison Array.

"Huh?" The demon had thought that victory was within its grasp and that its scheme had succeeded. Little did it expect that Xiao Yi would send a helper at a crucial moment like this. The helper had traveled through the void and managed to rescue Xiao Yi.

The evil demon was extremely annoyed, but it also knew that it was already impossible to catch Xiao Yi off guard.

To deal with Xiao Yi alone, it had to rely on cunning tricks. Now there was one more person, how could it get any benefits?

It cursed in its heart, and the demon did not continue to fight. It turned around and was about to slip away.

However, the demon did not discover that at the moment when Xiao Yi flashed out from the void, he had secretly activated a small mirror of black and white colors.

It was the Yin-Yang Mirror that Xiao Yi got from the stone pillar of the Immortal Mansion.

He threw it into the air, and the mirror shot out thousands of rays of black and white scattered light. The demon, who was about to escape, was fixed in place.

The demonic beast, who was insufferably arrogant, suddenly felt its Mind Sea tighten. Then, it was terrified to find that its own soul was not working smoothly.

"You actually have a magic treasure that specializes in the absorption of one's Divine Soul? I'm actually underestimating you." The demon glared at Xiao Yi as it tried to think of a way to escape. However, it wasn't terrified because it knew how strong its physical body was. Xiao Yi wouldn't be able to do anything about it for the time being.

However, he didn't expect Xiao Yi to sneer coldly.

With a wave of his hand, a dark blue thin stick was held in his hand. He mobilized his True Energy, and his body suddenly rose up to the sky. As Xiao Yi jumped up, the thin stick that had been held together with his palm instantly changed to a few feet long. The two of them held each other's thick body. The blue light on the stick flashed and carried a mountain-like pressure.

"I'd like to see if you, an invulnerable monster, can resist my stick?" Xiao Yi shouted in a low voice as he held the Spirit Convergence Needle in his hand. He looked down from high above and descended from the sky.

The giant cudgel made a whistling wind, and there were a fierce sound and a series of sparks in the air. Like a mountain, it patted the demon, which had been frozen.

"Ah!" Seeing the huge shadow falling from the sky, the demon was completely moved at this moment. It let out a threatening scream and tried to escape with all its strength. Unfortunately, its spirit couldn't run, and it couldn't move anymore.

"Spare me, I'm willing to serve you..." the evil demon screamed.

However, before it could finish its words, it had already smashed on its body with the whistling wind and the mountainous weight.

"Bang!" "Bang!"

"Puchi!"

Peng!

After three loud sounds in succession, this courtyard once again became completely unrecognizable. A huge deep ditch rested in the courtyard, and earth and debris flew everywhere.

Looking at the bottom of the trench, it was already a mess.

A pool of shredded meat wrapped in black ink spilled out in all directions, scattering at the bottom of the ditch.

The invulnerable demon was smashed into minced meat by Xiao Yi's stick.

The Spirit Convergence Needle was filled with the essence of the water, and it had the power of thousands of tons. After being used by Xiao Yi with all his strength, even a King Kong would be broken, let alone this demon.
