(PS: I recommend a good book "Evil Slave", the author is arrogant!)

The distance of more than 100 miles is not long, but it is not short. It would take almost a whole day to be a mortal. But if Xu Lin and the four of them were advanced in cultivation, even if they walked over step by step, it would only take half an hour.

But even in the past half an hour, neither Xu Lin nor Tiangui had a good-looking look on their faces. The closer they got to the thunder area, the more pronounced the roar they heard.

The roar was filled with the negativity of violence, killing, and blood. As Xu Lin and the others gradually approached the thunder area, the roar swept over like thunder, falling on Xu Lin's ears, making them all feel a little buoyant all over their bodies.

When they came to the edge of the thunder area, Xu Lin's faces were already white. There was a terrifying look in their eyes, because they found that in this area that had been shrouded in thunder for nearly five hundred miles, the thunder that kept falling did not make any sound.

In the past, no matter any thunder fell, there would be a "click" sound, but here it appeared silently, and then fell silently. The only sound was that roar, standing at the edge of the thunder area at this time, Xu Lin first felt that the blood in the blood vessels in his body began to slowly boil, a hazy red light appeared in front of him, and there was a faint idea in his heart to let go of everything and kill indiscriminately.

The roar continued, and each roar, like a drumbeat, struck directly on their hearts, and they felt a little dull, as if a stone weighing a thousand pounds was pressing on it.

"What a terrifying voice!" Xu Lin urged the sword of wisdom in his mind, a little emerald green light bloomed in his mind, spread out, and a cyan gas appeared around Xu Lin's body, accompanied by a cold feeling falling from the top of his head, and the cold feeling immediately made Xu Lin sober up. After coming to his senses, Xu Lin said fearfully.

"This area is very strange, there is nothing to attract thunder here, but there are still so many thunders. Tiangui's face was still pale, but at this time, there was a touch of solemnity. He has the highest cultivation and the most experience, and he knows that fear can't change anything, and the only thing he can do is to calm down and face it.

The same is true for Taixu and Tiger, both of them are beings who have already stepped into the ninth step. After experiencing the initial fear, I immediately calmed myself down. Looking into the thunder area, the area was relatively flat, and there were no peaks higher than five hundred zhang within a radius of at least five hundred miles.

There are countless types of thunder falling from the sky, among which the platinum thunder, the creation golden thunder, and the Yimu green thunder that Xu Lin has seen have all appeared in it. These thunderbolts continued to fall, and they all seemed to be heading towards the center of the area.

Seeing the scene in front of him, Xu Lin suddenly thought of a place he had been to, the thunder area in the Taigu Bronze Gate, which felt very similar.

"Taixu, do you think there will be a Taiji Thunder Pool in this?" It was Xu Lin who said this, and he asked subconsciously.

After listening to Xu Lin's words, Taixu's expression paused for a moment, and then a flash of realization flashed on his face. He moved his gaze to the Heavenly Rules, and said, "Listening to this roar, I'm afraid it's a demon or demon from the primeval period that has been suppressed inside." It is very likely that the Taiji Thunder Pool that Xu Lin said is used to suppress the existence of this thing. ”

After hearing this, Tiangui's face showed a contemplative look. After a while, Tiangui said in a deep voice: "There is such a possibility, but it is not necessarily. Listening to this roar, the source is definitely an existence equivalent to the ancient emperor, and if I encounter it, I can only flee immediately. ”

He frowned for a moment and continued: "This area seems to have been set up by a super powerhouse to set up a forbidden formation, shrouding a thousand miles of radius, I am afraid it is used to besiege that terrifying existence. We accidentally got in, and now it's hard to get out. There is not the slightest flaw in this forbidden formation, I can't find a way to crack it, and now if I want to go out, I can only go into the central place and look for it there. ”

The meaning of Tiangui was very obvious, he couldn't break this forbidden formation that shrouded a thousand miles around, if they didn't want to fall here, they could only continue to move forward and go to the center of the area to find a way to leave.

Xu Lin and Taixu had no choice, and after thinking about the way of the heavenly rules, then both of them nodded helplessly. Tiangui saw the two nodding, a trace of bitterness flashed on his face, and after nodding to the two, he was about to go to the thunder area.

At this moment, the tiger suddenly spoke: "Wait a minute, I seem to have seen such a forbidden formation before. Well, I seem to have seen it. The tiger frowned, and the "king" on his forehead was wrinkled, and he couldn't see the original appearance at all.

"Have you seen it? What kind of prohibition is this?" Tiangui paused, his face showed surprise, and he asked the tiger.

"I have the impression that this ban is called... What heaven and earth lock element tire. The tiger's eyes were a little confused, and his tone was very unconfident.

"Heaven and Earth lock the Yuan Fetus!" Who knows, as soon as Tiangui heard the forbidden name of the tiger, his face showed a look of horror again, and his eyes were full of disbelief.

"How is it possible? How can this prohibition still exist?" Taixu muttered with the same shocked face.

"Is this prohibition very famous, very powerful?" Xu Lin looked confused when he saw the expressions of the two.

"There is more than just a name. Among the three thousand avenues born in the origin of the Great Dao, the only avenue that prohibits the formation, the Zhenlong Heavenly Bureau. This Heaven and Earth Lock Yuan Fetus was derived from the Zhenlong Heavenly Bureau, and in the primeval period, it was known as the existence of blocking heaven and earth. With heaven and earth as a lock, it is possible to seal anything in it. Tiangui said with a wry smile.

"Three Thousand Great Avenues, Zhenlong Heavenly Bureau!" Xu Lin is not a fool, he knows several kinds of Three Thousand Great Avenues, so he naturally knows the power of these Three Thousand Great Avenues. This Heaven and Earth Lock Yuan Tire can use Heaven and Earth as a lock to seal anything in it, just by listening to this name, you can know how powerful it is.

"Is there a solution?" Xu Lin, who reacted, asked stupidly.

"This Heaven and Earth Lock Yuan Fetus has disappeared in ancient times, and there are very few people who know this sealing method. However, I have heard of an emperor who was trapped in this Heaven and Earth Lock, and it took a full two thousand years to get out of it. And the first sentence after he came out was: Heaven and earth lock the primordial fetus, and the existence of nine deaths and one life. ”

Tiangui said: "There is a solution to this heaven and earth lock primordial fetus, which can be seen from the nine deaths that the emperor said. Nine deaths, but there is still a glimmer of life. ”

Hearing Tiangui's words, Xu Lin's face suddenly showed a little hope, he moved his gaze to the thunder area, and said: "It seems that we really have to go inside to find that glimmer of life, you can't crack this Heaven and Earth Lock Yuan Fetus, we can only take risks." ”

Hearing Xu Lin's words, Tiangui and Taixu were silent at the same time, and after the tiger said a few words, he also closed his mouth. None of them are stupid, and a super power has arranged something that is close to a desperate formation, such as the Heaven and Earth Lock Yuan Fetus, and you can completely imagine what kind of level the thing or person that super power wants to lock is. If it is a person, if that super power does not kill him, but only seals it with such a near-desperate prohibition, will he not be able to kill him? Or do you not want to kill him?

Turning around, Xu Lin and the others swallowed their saliva with difficulty at the same time. Whether they can't kill it or don't want to kill it, they can't afford to provoke it. Now they have no choice but to enter it and find life, which is an immensely great adventure for them.

Thinking of this, Xu Lin's faces became a little unnatural. Although he had calmed down, he thought that he and the others might approach a living, equivalent to an ancient emperor-like existence. They still felt a creepy and cold terror in their backs.

Fortunately, a few people are still determined, and they can't find any way. Xu Lin and the others still stubbornly plunged into the thunder area.

Thunder and lightning appeared silently in the sky, and then fell silently. There was a roar in the distance, and such an environment was indeed a little creepy. Xu Lin and the others walked in the thunder and lightning, and the heavenly rules summoned the texture of heaven and earth to form a guardian light curtain, enveloping them all, and the thunder and lightning fell above their heads, which could only stir up a circle of ripples above the light curtain, and could not hurt the people inside at all.

There was no threat above their heads, but Xu Lin and the others still raised their hearts to their throats one by one at this time, and the steps under their feet were also very slow. As if they were going to die, although Xu Lin did not have heroic pride on their faces, they were also dignified.

"Roar!"

In the middle of the Thunder Zone, the roar continued. Like a wave, wave after wave swept in, falling on Xu Lin's ears, and their hearts brought extremely huge pressure.

"It seems that this ancient secret realm was born a little early. At this time, Taixu suddenly felt a little regretful. He didn't expect that there would be such a big crisis in this ancient secret realm, and the traces of the existence of the ancient emperor appeared one after another, which had completely made the situation jump out of his palm.

However, even regret will not help. Taixu came back to his senses, glanced at Xu Lin, and saw the resolute look on Xu Lin's face at this time. He sighed secretly in his heart, and then calmed down, his face changed to a solemn color, and his eyes became cautious and vigilant.

"Roar!"

As they approached step by step, a huge pressure appeared in the space amid the roar.
