Then the light was thrown into the air by it, the entire secret room was like daylight, and the next scene made Lin Ming speechless in surprise, there were all kinds of strange-shaped wooden stakes around it, and different patterns were drawn on this wooden stake.

These patterns correspond to the formations on the ground, each of which is different but reveals mystery and weirdness, Lin Ming suddenly became interested, and was woken up by Wu Kun, "Are you interested?"

"General Wu, this is ......"

Wu Kun's eyes narrowed slightly, and he smiled very proudly: "Battle array!"

"Battle array!" Jin Ming blurted out at the same time, and the words of the two made Lin Ming stunned, "This is the legendary battle array, the battle array researched by the ancient god of war?"

He rubbed his eyes in disbelief, but when he saw Wu Kun nodding again, he believed it, "Lin Shao, these battle formations are very mysterious, not ordinary formations!"

Jin Shi also frowned, he had never seen such a mysterious battle formation, even if he had followed the Red Emperor for so many years.

The battle formation in the mouth of the golden crow is actually a kind of formation handed down from ancient times, they are mostly created by the ancient powers, it is rumored that its originator is the god of war Xingtian, there are countless formations, and its main functions can not escape attack and defense, of course, there is also a kind of isolation of heaven and earth to breed aura.

This is fundamentally different from the current formations, because these formations need to draw a formation diagram, and if you want to start a large array, you also need a large load of aura supply, of course, the cost is also great, and the attack and defense power are amazing, and those who have the formation can even jump to the next level.

Moreover, if this kind of killing array is used on the battlefield, it will be a powerful war machine, and tens of thousands of people will be wiped out in an instant.

This is why Wu Tian was called the god of war back then, and laid down such a world for the Netherworld Imperial City, and the battle array played the role of a mainstay.

However, due to the fact that the Wu family's military power was withdrawn after Wu Tian's death, these battle formations never appeared in the Netherworld again, but Wu Kun has been secretly studying these formations, and now they can be regarded as small achievements.

And he brought Lin Ming here today to pass on this family stunt to Lin Ming, I believe that with it, Lin Ming's strength can be doubled several times, "No wonder this Wu Kun said that there is a way to help me improve my strength, it turns out that the Xuan level is in this battle array!"

Thinking of this, Lin Ming's blood couldn't help but boil, "I didn't expect to be able to see the legendary battle formation here, Lin Ming is indeed blessed with eyes." ”

"Not only do I want you to see it today, but I also plan to pass it on to you! The Imperial City Challenge is coming, you only have three days to penetrate this battle formation, are you confident?" Wu Kun asked.

Although Lin Ming had already guessed, he couldn't help but show a look of shock, "The battle formation, something that has been handed down from ancient times, three days," Lin Ming couldn't help frowning and falling into deep thought.

Wu Kun was also anxious when he saw Lin Ming's expression, "Isn't three days enough?" If it really doesn't work, I'll help you understand it on the side, maybe you can comprehend it faster!"

Seeing that Lin Ming had no confidence, Wu Kun's seriousness couldn't help but reveal a little worry, this was his only hope, so he definitely couldn't fail, besides, Lin Ming already knew the secret of the battle formation of the General's Mansion, so it could only be him!

But Lin Ming was still pondering, "If it still doesn't work, then I'll let people give you ...... in the first game" Before the words in Wu Kun's mouth were finished, Lin Ming actually raised his eyebrows and said in a deep voice something that made him think he had heard it wrong, "If you can, give me a day!"

"One day!" Wu Kun gasped, he rubbed his ears vigorously, "How is it possible?" Lin Ming, are you sure what you said is true?"

But Lin Ming nodded vigorously, "Of course it's true, I don't believe you can test me in a day," he smiled easily.

But Wu Kun still couldn't believe it, "Lin Ming, don't forget that there are dozens of killing formations here, each killing array is infinitely changing, and it can deduce thousands of transformations, you are exaggerating too much in one day!"

"The gentleman has no jokes, and after a day he will not fully understand that I am willing to sacrifice the head of the Xiangshang!" he said categorically.

"Okay, since you are so confident, I will believe you once, anyway, your kid has a lot of means!" he nodded and glanced at Lin Ming very appreciatively, and then he explained some other matters and walked out.

The smile on Lin Ming's face immediately froze as he watched Wu Kun leave, he turned his head to look at those battle formations, and his brows were cold, "Bodhi, how much do you know about this battle formation?"

"It's not a lot, but it's okay to take you to get started," he whispered and transmitted the memories of the battle formation in his mind to Lin Ming, who snorted and looked extremely pained.

After all, it was to force some memories into his mind, and the expansion of his head just made his eyes fall into a short time, and then he stumbled and was about to fall, but the alienated Xiao Hei stopped with his back.

After a few breaths, he was relieved from the pain, and his eyes had already regained their vision at this time, and then he carefully skimmed through the memories of this battle formation, and raised his eyebrows, "Basically understood, let me delve into the formation diagram of these battle formations in the next time!"

At the same time, a white-clothed figure appeared in everyone's field of vision outside the Netherworld Imperial City, he looked handsome and neat, and a folding fan in his hand looked even more chic.

"This is the Netherworld Imperial City, not bad!" he smiled and walked inside.

This person is the son of Hou Yi, and he is also Hou Yun who has a relationship with Lin Ming, he came to the Netherworld this time for the demon clan, but when he heard that the Imperial City of the Netherworld held the Imperial City Challenge, he planned to come to join in the fun.

As soon as he entered the Imperial City, he was shocked by this magnificent Imperial City, "This Nima is even more majestic than the city of the Heavenly Realm!" he secretly admired and walked straight ahead.

A quarter of an hour later, Hou Yun looked at the young man in front of him with some impatience and whispered: "Ten thousand black stones!

"I won't sell 20,000 yuan, and who are you, why should I sell it to you?" the young man frowned and glanced at him with disdain.

But Hou Yun also frowned, "If 10,000 black stones can't work, then 20,000, do you sell them?"

"Twenty thousand, twenty thousand, of course...... Of course you don't sell it, you're too expensive for cabbage," he had a little hesitation at this time, but he still didn't say that he wanted to sell it after all.

Hou Yun saw that there was a door, but he was also a little impatient when he saw the young man's appearance, "Fifty thousand black stones, if you sell it, then sell it, if you don't want to sell it, I won't buy it." ”
