Three days later, eight figures stood in the sky above the second city lord. It was Nie Tian and others.
After three days of rest, Nie Tian's condition has returned to its best.
However, the pupil power of his Demonic Eye still has not accumulated and recovered.
He originally thought that the Demon Eye would recover within three days, but only then did he realize that only a small part of the Demon Eye's pupil power had been restored.
According to this recovery speed, it will take at least a month for the pupil power to be fully accumulated.
In other words, every time Nie Tian uses the Demonic Eye, he will have a one-month recovery period.
Moreover, the use of the Demon Eye must be coordinated with the stimulation of the power of gods and demons.
Therefore, although the Demonic Eye is very terrifying, it also has many restrictions.
Nie Tian did not wait too long because he was afraid that the Dark Emperor would know his plan and take precautions.
"Lord Nie Tian, let's go." Qi Lan stood beside Nie Tian and said calmly.
Nie Tian nodded slightly, and everyone moved together, heading towards the Heart of the Dark Sea.
About half an hour later, everyone arrived above a dark sea area.
Below them is a large dark island.
"Is this the Heart of the Dark Sea?" Nie Tian looked at the dark island below and frowned slightly.
He sensed that the entire island was enveloped by a powerful force.
This force is very strange, some are like formations, and some are like restrictions.
"Lord Nie Tian, this island is the Heart of the Dark Sea. Our current location is only the outermost sea area of the Heart of the Dark Sea, and has not yet reached the periphery of the Heart of the Dark Sea." Qi Lan spoke in a deep voice, obviously thinking about it.
Thinking about his past events, his eyes couldn't help but be a little panicked.
"Yeah." Nie Tian nodded and said to the little fat cat: "Little fat cat, can you see anything?"
The Heart of the Dark Sea is obviously protected by a huge killing array. It is hoped that the little fat cat can see through the killing array and find a safe route for Nie Tian and others.
The little fat cat was quiet for a while, then spoke after a long time, sighed, and said: "Nie Tian, the killing formation in front of us is very strange, the formation is strange, and the formation is illusory and unpredictable."
"If I want to break this killing formation, it will take at least several months."
When Nie Tian heard what the little fat cat said, he couldn't help but narrow his eyes and look very embarrassed.
This killing formation is really strange, and it would take months for the little fat cat to crack it.
Unfortunately, Nie Tian did not have so much time.
With so many of them coming to the Heart of the Dark Sea, they will soon alert the Dark Emperor.
Moreover, Nie Tian was in a hurry and could not wait for several months.
"It seems that the only option is to forcefully break into the killing formation!" Nie Tian then said with a steady gaze.
"Lord Nie Tian, do you really want to force your way in?" Qi Lan swallowed hard and looked at Nie Tian with a horrified expression and asked.
Nie Tian smiled slightly and nodded heavily.
Now that we have arrived at the Heart of the Dark Sea, there is no reason to turn around and leave.
The other city lords looked at Nie Tian and then at the Heart of the Dark Sea below, with equally frightened expressions.
Even someone with Qi Lan's strength was injured by the Killing Formation, which shows how terrifying the Killing Formation is.
"Nie Tian, please wait a moment and give me some time." At this time, the little fat cat's voice suddenly sounded.
Nie Tian was stunned for a moment and didn't ask too many questions.
Then, the figure of the little fat cat appeared, ignoring the surprised reactions of the spirit master and others, and kept releasing the energy of glass.
After a while, a small formation formed by condensed glass energy appeared, and eight formation eyes could be clearly seen.
The little fat cat now had beads of sweat on his forehead. He moved, returned to the Yuan Fei space, and said to Nie Tian: "Nie Tian, this is a miniature eight-sided array."
"In the formation, it will be easier for you to suppress the formation's eyes and use the eight-square formation as support to break through the killing formation."
"Okay." Nie Tian nodded and smiled, and was the first to step into the eight-sided formation.
The other seven city lords looked at each other and also entered the formation.
All eight formation eyes were occupied, and the eight-sided formation was slowly moving.
Nie Tian felt that his whole body was wrapped in the power of formations, making the aura all over his body much stronger.
Everyone else also discovered this and looked horrified.
Who would have thought that a little fat cat raised by Nie Tian could have such powerful abilities.
"Everyone, let's break into the formation together." Nie Tian smiled faintly, moved his figure, and swooped down.
The seven city lords all followed suit, keeping their formation unchanged, but with unconcealable horror on their faces.
They don't know what will happen next.
"Boom!" Just when Nie Tian and others were within 10,000 meters of the Heart of the Dark Sea, they directly broke through the killing formation barrier in the space.
With a bang, the killing array instantly opened.
The next moment, an extremely strange scene occurred.
"Boom! Boom! Boom!" Above the sea, countless giant black trees suddenly sprang up, like dragons breaking through the abyss, spreading towards the void.
"Whoa, whoa, whoosh..." Giant black trees grew in the air with claws and teeth, spreading across the entire space in an instant.
Above the sea, it is directly filled with black giant trees.
Nie Tian and others seemed to have arrived in a dark jungle.
Everyone looked at the dark wood forest below, with horror in their eyes.
"Wood Demon Killing Formation!" At this moment, the little fat cat's voice sounded, showing panic.
Before Nie Tian could ask any more questions, he saw that the black trees below were connected one by one, forming huge wood demons in an instant.
The appearance of the wood demon is somewhat similar to that of the tree man, but the size is different. The small ones are only a few meters long, while the large ones are hundreds of meters or even kilometers long.
"Is this the wood demon?" Nie Tian was stunned for a moment and screamed.
"Ouch!" The moment his voice fell, a shrill and piercing roar suddenly came from below. All the wood demons instantly went crazy, jumped into the air, and rushed towards Nie Tian and others.
The wood demon stretched out its huge black wood arms and waved them in the air, like a wild snake, dark and violent.
"Kill!" Nie Tian saw a wood demon charging up, and he roared, thrust out his sword, and the shadow of the sword flew out like a startling rainbow, and the brilliance of the sword bloomed ten thousand meters away.
"Boom!" The moment the sword shadow fell, a cracking sound sounded, and the wood demon's body was shattered by the bombardment.
"These wood demons are not that good." Upon seeing this, Nie Tian raised the corner of his mouth slightly and murmured.
What he killed with one strike of his sword was a wood demon nearly a kilometer in size, so those small wood demons would be even more vulnerable.
"Boom! Bang! Bang! Bang!" At the same moment, the seven city lords also took action, and pieces of broken black wood appeared in the mid-air.
"Fifth City Lord, is this the killing array you encountered? It's nothing more than that." Everyone defeated the first wave of attacks from the wood demons and killed many large wood demons in an instant. Yuan Ying couldn't help but said proudly.
"Don't be careless!" Qi Lan was very nervous and said loudly: "These wood monsters are not what you think. The bigger the wood monsters are, the weaker their strength is. Those small wood monsters are the most terrifying.
.”
When everyone heard Qi Lan's words, their eyes darkened and their faces became embarrassed.
The ones they just killed were all large wood demons.
But the small wood demon is stronger.
"Ouch!" At this moment, a louder roar sounded, and countless wood demons appeared, a mass of blackness, like dark clouds, charging towards Nie Tian and others.
