The Mulu Department is the best at business in the Heavenly Demon Ancient Kingdom, and most of the Heavenly Demon Clan caravans on the Ten Thousand Races Trade Road are from the Mulu Department.

Therefore, the Mulu Department was the richest in the Heavenly Demon Ancient Kingdom.

Ye Xuan was sure that the Mu Lu Department had invested money in the Ten Thousand Clans City, and immediately implemented the previous purpose of punishing the shrimp and the heart, and purchased ten floating light flying boats and engraved the name of the Mu Lu Demon King, as a way to thank him for his help to the Long Yuan Army.

However, before the time for these ten Mulu Demon King Floating Light Flying Boats to play, they were temporarily sealed in Wangbei City, waiting for the moment to exert their strength.

......

It took three months to build.

The Void Extinguishing Cannon was finally completed, and under the guard of the Night Stalker's Secret Guard, it was pulled to the deserted area in the south of Longyuan Prefecture, loaded with the Sun Devouring Astrolabe, and test-fired a shot.

Ye Xuan saw that cannon with his own eyes, and there is one word to describe it, that is, "spectacular".

After the test launch was successful, Ye Xuan immediately ordered to move the Void City over, install the Void Extermination Cannon, and then hide the entire Void City, waiting for the moment to launch an attack.

After three months of equipment improvement, the weapons equipped by the Longyuan Army have been upgraded to a higher level as a whole.

The number of siege weapons has doubled, with a thousand Fire Meteors and a thousand Floating Ships.

There are more other ballistas, chariots, and other equipment.

Three months later, in the early morning of one day, the main generals of the Longyuan Army gathered in the military machine hall.

The results of the armaments were reported one by one, tens of billions of spirit stones were smashed, and all the armaments were completed within the scheduled time.

After the armies reported their weapons and equipment, the morale of the soldiers in the military hall soared.

"With so many siege weapons, we can finally fight with the ancient capital of Hell. Pei Shanyue laughed.

Just looking at the current reported military strength, it has slightly surpassed the ancient capital of Zhenjiao.

However, this time the Heavenly Demon Clan has a city to defend, even if the military strength is slightly weaker, and after adding the protective array of the ancient capital of Zhenhe, it still has an advantage.

Therefore, just looking at the strength on the surface, it is still very difficult for the Long Yuan Army to break through the ancient capital of Zhenjiao.

Even if it is breached, it will be a pyrrhic victory.

Of course, this is the result of a superficial contrast of strength.

However, the truth is not as simple as it seems.

The entire battle situation, starting from the loss of the Void Spirit Blade, has already laid the groundwork.

So far, on the bright side, the Void Spirit Blade is still counted as the combat power of the ancient capital of Hell.

However, it will be known when the war begins.

In addition to this, there is also the secret weapon of the Void Annihilation Cannon.

This big guy, from the beginning to the end, only Ye Xuan, the elders of the academy, and the master of the refining workshop knew about it, and the news was not leaked to anyone.

After the completion of the Void Annihilation Cannon, Candle Yong and the elders of the refining department were all arranged to live in the small world of Void City, first, to block the news, and secondly, they needed to operate the Void Annihilation Cannon.

Due to the urgency of time, it was too late to retrain people to operate the Void Extinguishing Cannon, so they directly let Zhu Yong and them, the elders of the refining department, go to it.

Candle Yong and they didn't have any objections, after all, the Void Annihilation Cannon was created by them in three months, and it would also be the pinnacle of their refining career, of course, they wanted to operate the Void Annihilation Cannon personally.

......

"General, everything is ready, when will the war start?"

Qin Tai'a pondered for a long time and then ordered: "Pass the order, and in seven days, set foot in the ancient capital of Zhenjiao." ”

The first order was followed by the second.

"Summoning the night owl secret guard, the foreshadowing in the ancient capital of the prison can be prepared, and in seven days, it will be activated when the war begins. ”

Ye Xuan didn't know about this command, and asked curiously: "What is the foreshadowing in the ancient capital of the town and prison? I, who have entered the ancient capital of the town and prison, don't even know." ”

Mrs. Qin laughed and said: "You kid has your ability, and I have it too, and when the war starts, you will naturally know." ”

Ye Xuan thought for a moment and said with a smile: "What kind of foreshadowing can the Ancient Prison Commander have? I guess it's Minghuang, right?"

Qin Tai'a smiled and did not answer.

Ye Xuan didn't ask any more questions, and instead said, "Those ten Mulu Demon King Floating Light Flying Boats can play a role, right?"

"That's my third command. Send the order down, pull out the ten Mulu Demon King Flying Boats, see where there are a small group of Heavenly Demons, pack them up and put them back. "Qin Tai'a gave the third order.

Give it a command.

The ten Mulu Demon King floating light flying boats sealed in Wangbei City slowly rose into the air and flew out of Wangbei City.

In the Xiling Mountains, at the southern end, there is a conflict between the Heavenly Demons of the Séance Department and the Terrans.

Ten Mulu Demon King Floating Light Flying Boats sailed over, crippled all the Heavenly Demons, but they just didn't kill them, and then left.

On the ten floating light flying boats, the eye-catching symbol of the Mulu Demon King was deeply engraved into the minds of these heavenly demons.

In less than a day, news of the collusion between the Mulu Demon King and the Longyuan Army spread throughout the Heavenly Demon Ancient Kingdom.

The contradiction between the séance department and the Mulu department intensified in an instant, and even a local conflict occurred.

The séance department accused the Mu Lu army of colluding with the Long Yuan army to help the Long Yuan army buy the floating light flying boat.

The Demon King of Enma demanded that the Demon King of Mulu apologize in public and compensate thirty Floating Flying Boats.

The Demon King of Mulu insisted that this was a normal trade practice and resolutely did not apologize.

Relations between the two sides are becoming more and more stale.

Not only that, before the Longyuan Army came to the ancient capital of Zhenjiao twice, the Demon King of Enma used the Heavenly Demon Beast Rider of the Mu Lu Department as cannon fodder to push out of the city and send it to death, which further intensified the contradiction between the two sides.

In the end, the Mulu Demon King transferred the 100,000 Heavenly Demon Army belonging to the Mulu Department in the ancient capital of Zhenjiao, resulting in a significant reduction in the strength of the ancient capital of Zhenjiao.

After the Demon King learned that the army of the Mulu Department was transferred away by the Mulu Demon King, he suddenly came to his senses, thinking that this was Qin Tai'a's conspiracy, and immediately became vigilant, preparing to recruit the inferior Heavenly Demon again and expand the army.

However, without waiting for him to give the order.

The Longyuan army moved, and once again approached the city, thousands of siege weapons were set up, like a fierce beast with a bloody mouth open, trying to swallow this ancient capital that suppressed hell into its belly.

In the palace of the ancient capital of the town prison.

The Demon King of Yama immediately summoned the guards: "Hurry up, send a priest to the Mulu Ministry, and ask the Mulu Demon King to transfer the army back to the ancient capital of Zhenhe, and the matter between the two will be discussed after the battle." ”

At this time, Princess Yazheng walked into the hall with a proud attitude and said proudly: "Grandfather, don't panic. We don't need the power of those wastes of the Mulu Demon King, with me, we can destroy the Longyuan Army a hundred times!"

"Yazheng, don't you ......" The Demon King's face immediately showed surprise.

"That's right, I've already cultivated the magic tricks in the Haoyue Temple. Princess Yazheng raised her neck, her hands were spread, and two sword lights immediately appeared above her head, one dazzling and bright, and the other blue and sharp.

"Good! great! hahaha...... Qin Tai'a is dead this time!" The Demon King laughed wildly.
