Li Aotian was not surprised by the undefeated changes and the appearance of the clouds in the sky, because all of this was in his calculations.

Long before the second fight with Heiqi, Li Aotian had already planned carefully in his heart.

In order to resolve the crisis in Tianlong City, Li Aotian thought about it, and only thought of two possible methods.

One is to self-detonate two extermination demon pills, and the other is to let the undefeated impact the bottleneck of the seventh-level demon monarch realm, so as to lead the heavenly tribulation to break the situation.

In Li Aotian's opinion, although it is the easiest and most direct to detonate two Extermination Demon Pills to break the game, this is not the best policy, because the power of the Seventh-Order Eight-Star Extermination Demon Pill is too powerful.

Once the two seventh-order eight-star extinction magic pills were activated at the same time, the entire Heavenly Dragon City would definitely turn into ashes in an instant.

At that time, not to mention the countless living beings in Tianlong City, even Li Aotian himself was not sure that he would be able to save his life under such circumstances.

Although Li Aotian was not a good person, he thought that he would not be able to feel at ease if he had to take the lives of tens of millions of cultivators at once, not to mention that there were Zhou Tao's father and son and many Wang family members in Tianlong City.

It was precisely because he knew that the price of activating the Extermination Demon Pill was too heavy, so Li Ao Tiancai chose the second relatively safe method, that is, to let the undefeated impact the bottleneck of the Demon Monarch realm, thereby triggering the Heavenly Tribulation.

The undefeated cultivator had already reached the peak of the Demon King realm, because it sensed in advance that after the breakthrough of the cultivator, there would be a danger of leading to the catastrophe, so when he was in Feiyun City, Li Aotian deliberately instructed it not to continue to cultivate until he was ready to cross the tribulation.

Although he knew that the undefeated was not completely ready to cross the catastrophe, but due to the helplessness of the situation, Li Aotian secretly gave the undefeated an order to impact the realm of the demon monarch after destroying the black god-killing spear before, and for this reason, he also deliberately left the god-killing spear that was broken in two to the undefeated.

"Li Aotian, you're actually... How dare you calculate me, do you know what the consequences are!"

Feeling the glorious heavenly power emanating from the high-altitude clouds, Han Xi turned his gaze to Li Aotian again while being angry, and the cold murderous intent exposed in his eyes, even if it was a distance, made Li Aotian feel a chill down his spine.

"Calculate you? Where do you start with this, everything that happened in this Dragon City, isn't it your witch sect that is calculating others from beginning to end, how can I have such a great ability to calculate you." ”

Li Aotian couldn't help but roll his eyes and said.

"You don't come here like this, if you hadn't deliberately dragged me and distracted me just now, how could I not have noticed the strangeness of your spirit beast!"

Han Xi gritted his teeth and rebuked.

"You are wrong again, although the undefeated has been following me, but strictly speaking, it is not my spirit beast, and there is no mental connection between me and it, so it broke through the cultivation to trigger the heavenly tribulation, and I didn't know it beforehand. ”

Li Aotian pretended to be innocent and explained.

"I don't care what kind of excuse you have, you immediately order your spirit beast to stop breaking the mirror and let the Heavenly Tribulation end, otherwise I will be the first to kill you!"

Han Xi threatened angrily.

"It's a shame that you're still a witch saint who has lived for ten generations before and after, why don't you even have this bit of common sense, the heavenly tribulation is a thing that is transformed by the law of the Great Dao, once it is triggered, how can it be said that it can be terminated, don't be kidding!"

Li Aotian smiled bitterly and shook his head.

"You... Even if you can't terminate the Heavenly Tribulation, then you quickly let your spirit beast leave Heavenly Dragon City, the farther away the better, so that it won't affect the Reverse Tribulation Blood Light Array!"

After thinking about it for a while, Han Xi came up with a feasible solution.

"I'm sorry, I can't really help you with this, because... Because the Apocalypse has begun!"

Li Aotian raised his hand and pointed to the sky as he spoke, and then urged the Qiankun Cave to disappear from the same place.

"Roar!!

At the next moment when Li Aotian disappeared, an undefeated earth-shattering tiger roar sounded again in the distance, and along with the tiger roar, there was also a beast power of the seventh-level Demon Monarch realm.

"Boom !!"

Obviously, he felt the breakthrough of the undefeated cultivation realm, and within the blue tribulation clouds in the sky, thirteen dazzling blue thunder arcs suddenly burst out.

These thirteen thunder arcs, each of which is dozens of zhang long, if it does not look like lightning from a distance, it is not an exaggeration to say that it is a thunder pillar.

Before and after, before and after not even half a breath, thirteen dazzling blue thunder arcs, with the power of the Brilliant Heaven, fell fiercely on the blood-colored light curtain that was transformed by the Reverse Tribulation Blood Light Array.

With a blood-colored aura soaring, the thirteen blue thunder arcs that looked amazingly powerful were all bounced out by the blood-colored light curtain transformed by the Reverse Tribulation Blood Light Array, and the forbidden formation of this witch gate was actually a perfect block of the undefeated first wave of Heavenly Tribulation's attack.

"This Reverse Tribulation Blood Light Array is worthy of the forbidden formation of the Witch Sect, and it is really as Hei Qi said before, it has extremely strong defensive power, but unfortunately, this kind of thing has never been afraid of strong opponents!"

Witnessing the thirteen blue thunder arcs with his own eyes, the blood-colored light curtain that was turned into the Reverse Tribulation Blood Light Array bounced out, and Li Aotian, who had already hid on the roof of a tall building in the distance, muttered with a sneer on his face.

At this moment, beside Li Aotian, Xin Wuxi, Yin Zhen, Yu Tianheng, Lei Qianshan and Yin Feihua were all there, and several of them had already secretly received Li Aotian's divine sense transmission, and deliberately stayed away from the Dragon Mansion and the Wumen Holy Maiden.

"Li Daoyou, can you do this method, why do I feel that I don't have any bottom in my heart?"

Like Li Aotian, several people without a trace had also witnessed the scene of the thirteen thunder arcs being rebounded by the Reverse Tribulation Blood Light Array, and Yu Tianheng couldn't help but question.

"Don't worry, this kind of thing is the Heavenly Tribulation is transformed by the laws of the Great Dao, and it is notoriously unattainable and will not give up, even if the Witch Gate's Anti-Tribulation Blood Light Array is powerful, it will not be able to withstand the indiscriminate bombardment of the Heavenly Tribulation!"

Li Aotian said confidently.

As soon as he finished speaking, a blue giant fist stretched out from within the clouds in the sky, and with an indomitable terrifying momentum, it smashed down towards the Reverse Tribulation Blood Light Array below.

This blue giant fist was nearly a hundred zhang in size, and its entire body was made up of blue lightning bolts, not only did it look extremely gorgeous, but the true yuan aura it exuded had already surpassed the limit of the Dao Monarch realm and reached the true Saint Rank level.

I only heard a shocking sound of "boom", and a huge blue fist with a size of nearly 100 zhang smashed heavily on the blood-colored light curtain transformed by the anti-tribulation blood light array, and smashed the blood-colored light curtain out of a huge gap.

As the blood-colored light curtain was pierced through a gap, in an instant, the huge blood-colored light shield that enveloped the entire city completely shattered......
