"Bang!" The door to the exit closed by itself!

Seeing that the gate was suddenly closed, Hao Yu and the others immediately stopped, looking in horror at the gate that had been closed.

At this time, the door has been closed, and the outside scene cannot be seen at all, and it is completely closed.

There was a faint light on the gate, and a layer of light curtain covered it, completely covering the gate inside, and the top of the light curtain was surrounded by secret dense runes, and the power of the runes formed ripples, constantly spreading around.

"Seal!" the bad dragon frowned.

"Is there a way?" Hao Yu asked, looking at the bad dragon.

Hao Yu knew that although the bad dragon was usually not serious, but after living for a long time, he still had a lot of things in his stomach, and he could see this seal at a glance.

"Attack a seal vigorously, quickly!" said the bad dragon seriously, immediately becoming serious, and putting away his usual giggle.

"Okay!" Hao Yu nodded.

Hao Yu began to operate the power of his body, the runes in his body began to work, and Hao Yu even tried to mobilize the power of the beast spirit diagram, but it was unsuccessful.

Immediately afterward, a flame red light appeared outside Hao Yu's body, and the runes on his body were surrounded, and the green dragon, the white tiger, the vermilion bird, and the Xuanwu transformation were all around the body along with the runes, accompanied by a trace of thunder and lightning.

At this moment, the two caves in Hao Yu's body began to run wildly, and the majestic power began to spread, and quickly spread to Hao Yu's body, blessing the power outside the body.

In an instant, Hao Yu's entire person was immediately covered in a layer of majestic power, and bursts of terrifying ripples of power spread to the surroundings, forming a gust of breeze.

Seeing Hao Yu's process of mobilizing his strength, the bad dragon's eyes widened, his mouth opened wide, and he showed a shocked expression.

The bad dragon couldn't help but swallow his saliva and exclaimed, "Monster, it's really a monster, even my eldest brother, it's nothing more than that!"

Just when the bad dragon couldn't help but marvel, the light of Hao Yu's body began to change again, and the fiery red light was immediately covered with a layer of golden light, and then, a force visible to the naked eye continued to rise from Hao Yu's dantian and spread to the limbs.

Hao Yu felt that he had adjusted his state to the best, and the multi-layer power superposition had been completed.

Hao Yu opened his eyes, and two rays of light shot out from his eyes, and the dragon of the second inner mansion in his body also opened his eyes at the same time.

Immediately after, Hao Yu rushed directly to the gate, mobilized all his strength, concentrated his right fist, and hit the gate with all his strength.

"Roar!"

"Huh!"

"Shhh

"Boom!"

The dragon roared and the tiger roared, the Vermilion Bird and the phoenix roared, and Hao Yu's fist swung out, carrying the transformation of the four divine beasts, and surrounded by thunder and lightning, and directly blasted towards that gate.

At this time, even the few people who were already behind Chenxi, they all felt the slightest shock, this power was really terrifying, at this time, Hao Yu was like a young emperor, with a kind of invincible bravery, attacking that gate.

"Boom!"

"Boom!"

When Hao Yu's fist collided with the door, there was a loud noise, and the entire library began to shake, and the bookshelves inside also kept shaking.

However, what is shocking is that the whole library seems to be shaking, but the door is still unmoving, still as steady as Mount Tai, not shaking in the slightest, and seems to be stronger than the whole library.

However, the library vibrated for a moment, and then it was quiet, and there was no more movement, and even the bookshelves were no longer disturbed, and they were all quiet.

The library and books were affected by the energy, and immediately covered with a layer of runes, protecting the entire library.

"This ......," the little flying leopard exclaimed.

The little flying leopard has never seen Hao Yu mobilize such a powerful force, under normal circumstances, this kind of power not to mention destroying this small library, even if it is a big mountain, it is estimated that half of the mountain will be lost after a blow.

But now, Hao Yu can't shake this gate, and this gate, under such a big attack, didn't even move, which is too incredible.

"Trouble!" said the Bad Dragon with a frown, looking preoccupied.

"Did you come up with any clues?" Hao Yu asked, turning his head to look at Huailong.

In fact, this result, Hao Yu also expected. How can such an important library not have some protection, and how can the protection of this kind of treasure-type library be weak.

"I see!" the bad dragon nodded, as if thinking of something.

"What?" asked the little flying leopard.

"It's ...... I don't know!" The bad dragon seemed to want to say something, and then suddenly choked out a "I don't know".

"Itchy skin?" Hao Yu glared at the bad dragon.

Seeing him so confident, I thought there would be some useful information, but I didn't expect that his appetite was hoisted, and in an instant, he came to "I don't know", all of which looked very bad.

Seeing that Huailong was still so unreliable, Xiao Feibao glanced at the bad dragon with a look of disgust, then looked at Hao Yu and said, "Do you know what's going on?"

He couldn't understand why Hao Yu suddenly called them out, and how Hao Yu knew that this door was going to be closed.

"There's a problem here!" Hao Yu said with a frown.

"What's the problem?" Dawn asked, her mind full of questions.

Just now, Hao Yu was reading a book with her, why was he suddenly so nervous, he pulled her and rushed out.

"As far as we know before, the Martial Arts Academy has been destroyed in ancient times, completely turned into ruins, and has been sealed for a long time. But just now, this place actually recorded what happened in our village in the past few decades, don't you think it's strange?How can there be things from Thunder Village in a place that has been sealed thousands of years ago?" Hao Yu said as he looked around.

"Shhh

Hearing Hao Yu's analysis, Bad Dragon, Little Flying Leopard, and Dawn all showed frightened expressions, and immediately looked around in a panic, looking for something.

"No need to look for it, no one is here!" Hao Yu said seriously.

"Scared the hell out of me!" the bad dragon breathed a sigh of relief.

Immediately afterwards, he glanced at Hao Yu and said, "You are like this, aren't you kind? People are scary, but they will scare people to death!"

"I didn't scare you! Think about it, the seal is long, who can come in here, and who will come here, and write down these things. Moreover, how could there be such a powerful seal in the gate here, it was obvious that there was no need to set up such a powerful seal here before the Martial Arts Academy was damaged. Unless there's something important here, or after that, something has come in here and laid out everything here. So, there must be a big problem here. Hao Yu analyzed seriously.

"You mean there's a ghost here?" said the bad dragon coldly.

As soon as the bad dragon's words came out, Chenxi and Xiao Feibao suddenly felt their scalps tingle, their backs cold, and there seemed to be a cold wind blowing, and goosebumps all over their bodies rose.

", don't talk nonsense here! Surprised, a ghost is the first to look for you. Hao Yu gave the bad dragon a blank look.

The bad dragon smiled bitterly, and was angry in his heart, and wanted to say, it is you who say that there is a problem, and it is you who says that there is a weirdness, so I will analyze it normally, okay?

"What the hell is going on?" asked the little flying leopard again.

He also wondered how this could be, since there was no one here, and there was no such "ghost" or anything like that, why was this place so weird.

Hao Yu looked at the little flying leopard and shook his head, and said, "I don't understand either!"

In fact, although Hao Yu discovered the anomaly and reacted, Hao Yu also didn't know what was going on, why this place was suddenly closed inexplicably.

"Is there any other way to get out?" asked the little flying leopard.

"A hard attack will definitely not work, and the solution may still have to be found from inside this library!" Hao Yu said.

Hao Yu knew in his heart that he used so much strength just now, but he couldn't shake the gate for half a point, and then, according to their current strength, even if a few people attacked together, it would definitely be useless, so they could only think of other ways.

"Is there anything else you can do?" Hao Yu asked, looking at the Bad Dragon.

In addition to Hao Yu, he is more familiar with the formation seal of the bad dragon, and his formation attainment, at present, is obviously much higher than Hao Yu, and he has the strength to break the formation that cannot be underestimated.

"This formation is very unique! Even the attack of that magnitude just now did not shake half a point, which is really surprising. It stands to reason that the general formation, when facing a powerful attack, will still shake a little, even if it does not hurt the formation itself, the large formation will not be incomprehensible. However, the attack just now had no effect on it at all. The bad dragons also frowned.

"Is it possible that the source of the array is here!" Hao Yu asked.

"Array Yuan, speaking of which, I think there's something that might be useful!" the bad dragon suddenly realized.

"What's that?" Hao Yu then asked.

"That little cup!" said the Bad Dragon.

"You mean the Formation Cup?" Hao Yu asked uncertainly.

"It's the cup. If you guessed correctly, that cup was the famous Formation Pattern Jade Cup back then, this is a Kui treasure, and it has amazing results when used to break the formation. Back then, many people fought for this cup, but their heads were broken and bleeding, and the first formation family was slaughtered all over the house because of having a formation cup, which can be described as guilty. It can be seen how attractive this little cup is. The bad dragon said seriously.

"Dare to hit his attention, I can't beat you!" Seeing the eyes of the bad dragon, staring at the formation cup, as if seeing a big beauty, Hao Yu immediately solemnly warned.

"How can I be, such an upright person!" said the evil dragon in a righteous manner.

"Can you still have a pleasant chat!" Hao Yu glared at the bad dragon.

"Let's look around, you take out the Formation Pattern Jade Cup, and see if there is any induction?" the bad dragon immediately changed the subject.

Hao Yu gave the bad dragon a blank look. But the pattern was taken out anyway.

In fact, Hao Yu basically agrees with the idea of the bad dragon, and the formation quilt does have its own uniqueness, and every time it reaches a critical moment, it can play an important role, and it is also very effective for the layout and cracking of the formation.

Hao Yu took out the array quilt and immediately poured power into the array cup.

That's when ......
