As for where this origin came from, no one knows, and the city lords of Dongji City in the past dynasties seem to be very taboo about this issue, so it has not been handed down.

"You go and rest first, I still need your help tomorrow." Huang Yin glanced at Ye Cangtian and motioned for him to go down first.

Ye Cangtian nodded, "Then I'll leave first, if the city lord has anything, just send someone to find me." After saying that, he walked towards the outside of the City Lord's Mansion, and soon disappeared from Huang Yin and Huang Min's sight.

Looking at Ye Cangtian who was leaving, Huang Min sighed, "Are you going to take him to the pivot point?" ”

Huang Yin nodded, "That's right, you also saw that it only took him less than a day to recognize the Lord and successfully defend the control of the Great Array, this talent is really terrifying." ”

"But the pivot point is the deepest secret of East Pole City, and Shicang is still ......" Huang Min didn't continue, but Huang Yin already knew what Elder Taishang meant.

"Secret?" Huang Yin sighed, "It's all because we are too pedantic that this secret has been buried until now, and now that I finally came across such an opportunity, I naturally won't give it up." ”

Huang Yin looked at Elder Taishang seriously, "I feel that this is the only chance for East Pole City, we must seize it, once Ye Cangtian successfully cracks this secret, then we will really change the world!" ”

Huang Min's heart was also flying, what the city lord said was right, if they really cracked this secret that had been hidden for countless years, then their East Pole City could immediately surpass Xihai City and become the largest city under the Demon Domain Imperial City!

The reason why the imperial city is so unbreakable is because they have some of the secrets of the city.

Once they also grasp this secret in the East Pole City, it may be possible to compare with the Imperial City, or even surpass the Imperial City!

Thinking of this, Huang Min finally made up his mind, "Okay! It's up to you! Take Shicang to the pivot point tomorrow! ”

Whether East Pole City can rise depends on Ye Cangtian!

The time of the day passed quickly, and when the sun just rose the next day, Huang Yin came to find Ye Cangtian, the two were speechless all the way, Huang Yin directly took Ye Cangtian to the deepest part of the City Lord's Mansion.

"What is this place?" Ye Cangtian frowned, he sensed a familiar aura from this.

"This is the pivot point of East Pole City." Huang Yin sighed with emotion, "Or, this is the core area of the war fortress!" ”

"War Bastion?!" Ye Cangtian's heart was shocked, it was really the handwriting of a mechanical master, and with a core, it must not be an ordinary thing.

"I guess Xing'er has already told you." Huang Yin didn't look back, and said to himself, "Although each main city has a name, it was also a later one, in ancient times, they only had one name, and that was the War Fortress!" ”

"City Lord, how much do you know about this war fortress?" Ye Cangtian asked tentatively, although Huang Xing had said a lot to himself, Ye Cangtian knew that there must be more secrets, and even Huang Xing didn't know.

Huang Yin smiled bitterly and shook his head, "Actually, I don't know much, a lot of information has disappeared from generation to generation, and all that is left is fragmented information." ”

"Then tell me what you know." Ye Cangtian wanted to know the details of this war fortress.

"That's nature." Huang Yin nodded, "I only know that this pivot point is the key to manipulating the war fortress in East Pole City, and only by activating the hub point can the war fortress be activated." ”

Ye Cangtian nodded, "It seems that this pivot point really has to go." ”

"There's just one thing that makes me very weird." Huang Yin frowned, "According to the records in the classics, once the war fortress is successfully activated, the energy released in it is completely different from our world, and I have never seen it. ”

"Alien energy?" Ye Cangtian raised his eyebrows, could it be that the mechanical master of the Demon Domain really crossed over from other worlds like himself?

If that's the case, it's really interesting, a mechanical master from another world, if he can find some clues, then maybe he can directly find a way into that world.

When the time comes, with the same method, you can even find a way back to Earth.

Looking at Ye Cangtian, who suddenly became excited, Huang Yin wondered, what's wrong with this kid?

"Ahem!" Ye Cangtian also noticed his strangeness, and coughed twice, "Then I don't know why the city lord called me here today?" ”

Huang Yin looked at Ye Cangtian with a serious expression, "Since you were able to recognize the Lord and successfully defend the control of the Great Array in less than a day, it means that you are destined for it, so I think maybe you have a way to help us activate this pivot point!" ”

Ye Cangtian smiled bitterly, "City Lord Huang, you really think highly of me, I don't dare to pack tickets, I can only say do my best!" ”
