Meng Nan's figure quickly retreated, stopped in the air, and looked at the blood Jiao in the distance, his brows furrowed slightly.

"What a difficult battle array spirit......"

The previous three temptations, although he did not exert all his strength, but it was enough to detect the extraordinary current battle formation, not to mention the attack for the time being, the defense was almost leakless, and it was impossible to start at all.

"The heritage of the ancient relics for countless years is indeed not to be underestimated. ”

"Looks like it's going to be another tough battle......"

"The defense of this battle array is unparalleled, I don't know how the attack will be, maybe lure it to take the initiative to attack, and you can still get a glimpse of a flaw!"

Meng Nan's mind turned, thinking about how to break the formation, but after thinking about it, it seemed that in addition to attacking hard, he could only think of ways to induce the other party to take the initiative to attack, and then look for an opportunity to break the formation.

"Wait, why do I have to crack this formation?"

Meng Nan suddenly came to his senses, "My purpose is to help Mu Lao and Murong return to the land of the Sea Clan, according to what Mu Lao said, as long as they return to the clan and have Murong Na's patriarch's father, those people will never dare to act blatantly......"

"Also, Mu Lao is also from the Sea Clan, maybe he knows the origin of this battle formation, and I don't know if there is a way to crack it......"

With this thought for a lifetime, Meng Nan's heart suddenly moved slightly, and while carefully guarding against the blood Jiao in the distance, he pretended to be indifferent, separated a wisp of divine sense, and entered the Thunder Emperor's Palace.

At this time, in the space of the martial arts hall in the five halls and one garden of the Thunder Emperor Palace, the figures of the old servant and Murong appeared in a wide martial arts arena.

There were too many secrets involved in the Thunder Emperor Palace, and the existence of the Dongtian Sacred Weapon was too shocking, Meng Nan was unwilling to reveal too many secrets of the Thunder Emperor Palace, so he put the old and young in this ordinary martial arts arena.

"Mu Lao. ”

Meng Nan's divine consciousness turned into a figure and floated down in front of the old and young, for him who completely controlled the Thunder Emperor Palace, in this world of nearly 10,000 miles, he only needed one thought, he could appear in any area.

"Meng Gongzi. ”

"Teacher. ”

The old and young were originally confused, and they didn't know why they suddenly came to this strange place, and when they saw Meng Nan's figure appear, their faces suddenly showed a hint of surprise and shouted.

"Meng Gongzi, what kind of place is this?"

"How did we get here all of a sudden?"

"What about those guys?"

"You...... Nothing, right?"

The old servant was puzzled, and when he saw Meng Nan, he couldn't help but ask.

Meng Nan smiled slightly and said, "Mu Lao, time is pressing, I will explain to you slowly in the future, in short, this is an absolutely safe place, you can rest assured." ”

After a slight pause, he simply said about the Blood Jiao Battle Array, and looked at the old servant with a look of hope, "Mu Lao, what is the origin of this Blood Jiao Great Array, is there any way to crack it?"

The old servant's expression suddenly became solemn, "Blood Jiao Battle Array, this is troublesome...... This array ranked third among the many battle formations of our clan, second only to the first-ranked Demon Killing Battle Array and the second-ranked Sea Dragon Battle Array. The characteristic of this array is that after evolving into the spirit of the battle array, the offense and defense are balanced, and there are almost no flaws, except for crushing and destroying with absolute strength, no other method can be cracked in a short period of time, unless it ......"

"Unless what?" Meng Nan asked.

The old servant said: "Unless you can find out the location of the people in the main formation, it is equivalent to the eye of the battle formation, as long as this point is broken, this formation will not be destroyed...... I think those people just now, the one who is most likely to dominate the battle formation should be Gu Tianyu. ”

"Array of eyes?"

Meng Nan's eyes narrowed, and there was a glint of wisdom in his eyes.

"I'll try, Mu Lao, if you can't break the formation, I'm going to take you to rush over and force yourself into the eye of the Sea of Death, is there anything I need to pay attention to?"

The old servant's eyes lit up, and he said continuously: "This is also a way, but the Death Sea Eye is shrouded in my clan's Protector Array, and it needs a special technique to open it, otherwise it will attract a fatal attack, Meng Gongzi, you remember, if you can enter the passage under the Death Sea Eye, you must release me as soon as possible......"

"Okay, then you're ready. ”

Meng Nan nodded, and then this divine body gradually faded and disappeared in front of the eyes of the old and the young.

"Grandpa Mu, the teacher won't be in any danger, right?"

Murong, who had never said a word, looked at Meng Nan's disappearing figure, and said worriedly.

The old servant smiled, kept looking at the world in front of him, a trace of doubt flashed in his eyes, and said: "Young patriarch, don't worry, Meng Gongzi is a strange person, unfathomable, and he will definitely be fine." ”

"Well, I believe. ”

Murong nodded heavily, thinking of Teacher Meng's various miracles, the anxiety in his heart gradually calmed down.

......

Meng Nan was distracted and asked the old servant in the Thunder Emperor's Palace, although it was a long story, it was actually a matter of a few breaths, and the blood Jiao in the distance didn't seem to have the intention of taking the initiative, quietly in the air, his fierce eyes locked on Meng Nan, and after a while, he seemed to notice something, and a bloody light flashed in his bloodthirsty eyes.

"Terran boy, this seat will give you one last chance, obediently hand over the secret method of the old and young people and you......"

The huge mouth of the Blood Jiao opened and issued an ultimatum.

Meng Nan just came to his senses, his eyes flashed slightly, and a touch of coldness flashed, "Dream!"

"In that case, then you should die!"

Blood Jiao roared angrily in his mouth, and his huge body shook violently, and immediately rushed towards Meng Nan from a distance, with a fierce momentum, opening his teeth and claws, wanting to tear Meng Nan into pieces.

Of course, Meng Nan was not afraid, he carried the purple bamboo cane and did not retreat to counterattack, and his figure flashed slightly and rushed out angrily, heading straight for the blood Jiao.

Kill!

The attack of the Blood Jiao was extremely fierce, and the powerful blood of the Dao Dao burst out from the sharp claws, attacking and killing Meng Nan.

And Meng Nan's reaction was not slow at all, relying on his keen combat instincts, his breathing Haoran righteousness and his unpredictable three thousand thunder movement methods, and he fought with Blood Jiao.

In mid-air, the figure whistled and flickered, and the violent Yuan Force erupted and collided.

Boom Boom!

In an instant, the wind and clouds changed color, and the terrifying aftermath hit the sea, as if a tsunami was coming, and the terrifying waves rushed to the sky.

All of a sudden, the two sides were locked in a stalemate.

Judging from the scene, the Blood Jiao battle formation formed by the seventeen Sea Clan warriors obviously had the upper hand, and every time they made a move, they could defuse Meng Nan's attack and bring a certain threat.

However, Meng Nan is unpredictable, always able to avoid lethal attacks at critical moments, and occasionally counterattack, looking for opportunities to break the formation.
