Lu Chen's whole body trembled, staring at the scroll in his hand in disbelief.

Ground-level, this is a ground-level formation!

You must know that the formation is a way, the level is divided into four levels of heaven and earth Xuanhuang, and in the ninth intercontinental Babel Tower, Lu Chen was facing the ground-level formation - Eight Locks Gang Snake Formation because he wanted to save Lin Yu!

That formation is the Four Temples Babel Tower Guardian Array, I don't know how many people have stopped, if it doesn't happen to have something to restrain each other, that formation can't be broken even if it's a Taixu monk!

And this Moon Tide Hundred Sword Formation is actually a ground-level formation!

Lu Chen was a little excited in his heart, and then kept checking the scroll, the scroll had a large number of formation patterns, if it wasn't for someone who knew something about the formation, others wouldn't be able to understand it at all.

This is also why Aquaman Xia Jun threw this valuable scroll here, because Aquaman Xia Jun couldn't understand it at all, so he was reluctant to throw it away, and it was useless to keep it!

After checking it for a while, although Lu Chen was not ripe for the time being, he had some understanding of this ground-level formation.

The Moon Tide Hundred Sword Array, the formation can form a bright moon hanging high, and at the same time can cause the moon tide seawater, and the moonlight can form a moon sword, which can kill the mid-stage strength of the Taixu, and as soon as the moon tide comes out, it can trap any monk in the Taixu realm in the water.

Only the formation refining requires a fourth-order water-based spirit sword, and it requires one hundred and eight!

"One hundred and eight!" Lu Chen's eyes froze, and then he looked at the brocade box, only to see that there were already more than sixty brocade boxes, which meant that there were still more than forty left, as for the fourth-order water system spirit sword, with Lu Chen's current refining level, it was not difficult to refine it.

The difficulty is that it is all water-based spirit swords.

"Water Spirit Sword, I don't have a scroll to refine this kind of magic weapon at the moment!" Lu Chen shook his head, he could see that this ground-level formation was extremely strong, but it was not easy to lay it down.

However, it is certain that if the formation is once Mahayana, then there is no need for the Void Monk to be afraid.

After all, it is recorded in the scroll that once the formation is completed, even the middle stage of the Taixu will be killed, and any Taixu monk will be trapped as soon as the moon tide comes out, which means that the Taixu monk's ability to cross the void is useless.

"Good stuff!"

Lu Chen carefully put away the scroll, all he had to do now was to find the scroll for refining the spirit sword, and this kind of scroll, as long as there was money, it should not be difficult to find.

Suppressing his thoughts, Lu Chen knew that he couldn't come in a hurry, so he immediately put away the demon pills and spirit stones in the treasure room, and then left slowly.

A moment later, when Lu Chen appeared outside the city, he saw that the void passage had been opened, and this passage was extremely large, and at a glance, it looked like it was leading to the Nine Hells.

And before the passage, giant fish scrambled to swim in.

"Xiao Hei, let's go first!"

The voice of the giant fish came, Lu Chen smiled, and then nodded, and at this moment there was an old chicken and a little fat fish beside him, these two guys kept talking, and they seemed to have an extremely good relationship.

After a while, the group of giant fish in front of him finally disappeared, and the void passage in front of him also slowly contracted, and at the same time, the black fish also swam back into Lu Chen's body.

"Old chicken, little fatty, do you have a scroll for refining a fourth-order water system magic weapon?" Lu Chen looked at a chicken and a fish and said, in his mind, these two guys are from extraordinary backgrounds, and they may not necessarily have some knowledge.

The little fat fish dripped, and it seemed that he was not familiar with the refining weapon, and the old chicken walked back and forth on the ground, and said with some spirit: "Fourth-order, water-based magic weapons, oh, oh, oh, I have a lot!"

Hearing this, Lu Chen was overjoyed, although Lao Ji had been trapped for thousands of years, he could be regarded as having wandered in Heaven and Earth Kyushu back then, so his knowledge was definitely not weak.

"Oh, oh, in fact, the fourth-order magic weapon is useless to us at all, but it is only in the Yuanying realm, if it wasn't for the time rush that day, I would have wanted to take it out and give it to the plant, so that you can refine more magic weapons for the old crab them!"

The old chicken walked back and forth, it actually didn't know much about the refining process, and at the same time, it didn't have the patience to study deeply, but its memory was indeed good, even after thousands of years, the things he saw back then were still as fresh as new. ...,

And the fourth-order magic weapon in his mouth, with the current strength of Lu Chen and Lao Ji, was indeed of little use to them.

"If you want a sword, and if you want a water spirit sword, the grade must be at the fourth order!" Lu Chen felt a little joy in his heart, and immediately urged.

"Wait!"

The old chicken walks back and forth, his eyes closed, as if looking for it in a huge memory!

And Lu Chen waited quietly, if Lao Ji really had a refining method for a fourth-order magic weapon in his memory, then he only needed to find the corresponding materials to refine it, of course, the more important thing in the formation was the formation soul!

And at this moment, in the distance, the two figures were silent, and their eyes were staring at a few people outside the city, with a hesitant look on their faces.

"Those giant fish seem to have disappeared, Demon Heavenly Venerable, do you think we should do it?"

"Although there is no giant fish here, but Lu Chen is mysterious, I am afraid that things will change, and you don't see it, when Lu Chen and Sea King Xia Jun fought, we all thought that Lu Chen would definitely die, but this son was super unexpected again and again!"

"So, I'm a little afraid that Lu Chen still has hole cards!"

The Demon Heaven Venerable Lord said lightly, his cold gaze looked straight ahead through the cloak.

Hearing the words, Lei Ze Tianjun's face changed slightly, it is true, Lu Chen seems to be in the Yuanying realm, but in fact, the overall combat strength is definitely more than that, and the Void Ball has also been broken, so he should have the strength of the early stage of Taixu.

And this is just one of them, if Lu Chen still has any hole cards, then the matter will not be under his control!

If this idea falls in the hearts of others, he will definitely laugh disdainfully, a little monk in the Yuan Infant Realm, is he so terrifying?, but Lei Ze Heavenly Monarch and Demon Heavenly Venerable Lord have witnessed Lu Chen's mystery with their own eyes, and the Sea King of the rank is also dead.

Therefore, they cannot be uncareful!

"But it won't work like this, Lu Chen still has to face it, let's try its strength, if there are really hole cards hidden, we will leave immediately!"

The Demon Heaven Venerable Lord said cautiously, as a demon cultivator, he was also a key wanted target in the Four Saints, but he was able to survive for so long, which was closely related to his usual caution!

Beware of making a ship of ten thousand years!

If you are careless and arrogant and despise everything, then the end of the sea king who will fall!

"Okay, everything is as you say!" Lei Ze Tianjun nodded, and after the words of the Demon Heaven Venerable, his evaluation of Lu Chen became higher and higher, and he unconsciously regarded him as a pair of the same level

And when the two of them made a decision, there was also a sound of surprise outside the city gate!

"Uh, I'll give you a fourth-order water spirit sword - Red Carp Sword, this sword was unintentionally obtained by the master back then, but the power is average, roughly in the middle range of the Yuan Infant!"

The old chicken's pace stopped and said a little proudly, and at the same time, a fine light from the chicken's pupils attacked, and a white mark was immediately formed in front of him, and a large number of lines were printed on it.

These are the methods used to refine the Red Carp Sword.

Lu Chen's eyes lit up, he took out a spirit stone in his left hand, and then separated a trace of divine consciousness to enter, and then threw it out for a while, and the white mark floating in the air was sucked into the spirit stone.

In a moment, Lu Chen put away the spirit stone, and now the refining method of this red carp sword is also left in the spirit stone.

And under the investigation, Lu Chen also nodded slightly, the refining method of this red carp sword is not difficult, but the materials have some requirements, the most rare of which is the water spirit sand lapis lazuli!

But the water spirit sand, isn't this a specialty of the Ninth Intercontinental Spirit Devouring River?

Lu Chen's eyes lit up, he had a lot of contact with this thing at the beginning, but now as long as he returned to the Ninth Continent, the water spirit sand could be easily suppressed, of course, because he had to refine more than forty red carp swords, so this amount was definitely a lot.

As for lapis lazuli, this material was the first time Lu Chen had heard of it, and it seemed that he could only go to those trading markets to investigate.

Just as he was thinking about it, suddenly, the eyes of the old cock on the side flashed, and he immediately said: "Spatial fluctuations have a strong person coming, Lu Chen, quickly retreat!"

Lao Ji is a Tiangang Fire Fierce, although he needs a fire spirit stone to gradually recover his strength, but his cultivation is not there, and his experience is still there, and with the unstable space in front of him, he immediately felt it. ...,

Mighty monks are coming across the void!

As soon as the old chicken's voice fell, Lu Chen had already reacted, and his body immediately retreated quickly, and at this moment, where he was standing before, a strange figure appeared like a ghost, accompanied by a hand with billowing black smoke.

Fast!

Extremely fast!

If it weren't for the old chicken's reminder, that weird catch, Lu Chen would be afraid that something would have happened!

And at this moment, Lu Chen's body retreated rapidly, his gaze was extremely solemn, and he was able to step through the void, which meant that he was a Taixu monk, but in addition to the Sea King in the chaotic demon sea, could there be other Taixu monks?

Snort!

After failing to catch it, the figure finally appeared, and next to him there was also a figure appearing, a burly figure on the left, with a thick beard on his face, and a man on the right wearing a cloak all over his body, unable to see clearly, like a ghost.

And after seeing these two people clearly, Lu Chen's face changed, of course he had seen these two people, when he entered the Northern Hell Dragon Palace that day, he was one of the four Taixu cultivators!

Razor Heavenly Monarch!

Demon Heavenly Venerable!

I thought that these two people should have left the Chaotic Demon Sea, but who knew that they were still hiding here!

Lu Chen continued to ponder in his heart, and his footsteps also stopped, these two people are the existence of the same realm as Sea King Xia Jun, and now that they appear here, the situation has suddenly become dangerous.

'Lu Chen, it seems that you are extremely alert!'

Lei Ze Heavenly Monarch's voice came out, and they had previously used the ability of the Taixu Cultivator to cross the void, and they wanted to make a sudden move and quickly resolve the battle, but this still failed.

And now, if he wants to use the ability to cross the void, then Lu Chen is afraid that he is already alert.

'Hand over the Xuanxin Stone Origin, and the two of us will leave immediately!'

At this time, the voice of the Demon Heaven Venerable Lord also came out, and his voice was as piercing as a nighthawk, making people feel like their hairs were standing on end.

Of course, if the other party was really an ordinary Yuanying cultivator, the two Demon Heaven Venerable Lords at the moment would not say much at all, and directly wiped out each other, but in their hearts, this Lu Chen was mysterious and weird, if they acted recklessly, they might be bitten back by the other party.

And after the appearance of the two, a large number of demon cultivators in Blackfish City also found out, and immediately, the old crab people rushed out of the city gate, staring closely at the two powerful monks, of course, from Lu Chen's expression, they sensed the strength of the other party, so the old crab people did not rush forward recklessly.

For a while, the atmosphere in front of the entire Blackfish City was extremely depressing
