The path north of the Dreads of the Dead in the Black Earth was held back by the old adversary of the Roman Empire, making it impossible for them to start their plans to harvest civilization, and as a last resort, the Dreads began to build their own surface warships along the coast.

The Dreads do have the ability to create large flying machines to invade other continents, but these Dreads are a group of incompletely awakened sapient units, and they are not as flexible as the ancient Roman Empire led by the Legions.

In the course set by the Dreads, they must harvest the most knowledge with the fewest resources.

After analyzing the several human cities they had destroyed, the Dreads decided that the productivity of this world was low, and that this harvest was still a failed harvest, and that the resources and energy needed to build large flying machines were too large, and the harvest ratio was too low.

This was also the result that the current Supreme Commander's Staff Officer of the ancient Roman Empire wanted.

Through complex calculations, the staff officers also predicted that the speed of the ships created by the Dreads would coincide with the time of the all-round erosion of Chaos, at which point the Dreads' fleets would encounter the fleets of the Chaos Demons on the sea.

Using the Fear of the Dead to fight against their enemies is the most effective weapon that the ancient Roman Empire has discovered after awakening this time, and the last time it fought against the gods, the ancient Roman Empire had already tasted the sweetness, and this time was no exception.

For intelligent machines such as staff officers, the seemingly powerful death-fearing people are essentially no different from semi-intelligent construction machinery working on the construction site.

Since the maelstrom plan was finalized, based on the emergence of Xu Yichen's variable, the staff officers have made drastic changes to the existing plans.

It recalculated the site needed for the Maelstrom project and began to build on the existing underground setup.

Essentially, they want to build a turbine that drains the world's magical energy as quickly as possible, so the size of the vortex itself is naturally as large as possible.

In the plan conceived by the staff officer, the above-ground part of the Great Vortex Project would be a hollow cylinder with a diameter of more than two kilometers and a height of more than three hundred and fifty meters, and the engineering intelligence of the ancient Roman Empire did indeed start to act according to this requirement.

But this is not the real world, this is a world based on magic, and there may be taller buildings in the New World than the buildings planned by the staff, but they all rely on the power of magic to stand.

The buildings related to the Maelstrom Project must not use magical powers.

In order to build the above-ground part, the staff officers even did not hesitate to dismantle the underground bases of the ancient Roman Empire on a large scale in order to obtain enough qualified building materials.

But plans often don't change as fast as they happen.

The staff officer calculated in detail the bearing capacity of the entire building foundation and the maximum lateral force that the building materials could bear, but when the engineering intelligence increased the entire project to 177 meters with great efficiency, there was still a partial collapse.

After re-testing, the staff officer found that among the engineering intelligent machinery, there were three different intelligent machinery units in different positions with the underlying data confusion, and they sent unqualified building materials to the wrong position and used the wrong construction methods to construct them.

Thankfully, the mistakes they made were not serious enough to cause the entire project to fail.

But what worries the staff is that this is the first time that the intelligence of the ancient Roman Empire has been subjected to malice from Chaos.

The staff officer had tried to analyze the source of the code confusion of the three intelligence units, but the cost was that he still lost a quarter of his memory, and the code was like a virus, almost infecting the staff officer.

Fortunately, the staff officer was vigilant enough, and it used the method of isolated analysis to build a firewall for itself.

The entire above-ground works were temporarily suspended, and the staff officers had already sent a signal for help to the corps, and it did not know how to respond to such an emergency.

Even so, the half-finished product of the ancient Roman Empire became something that the Duchy of Sarion marveled at.

The members of the Lion Knights almost watched as the thing grew from nothing, growing taller and taller day by day, it was not a simple house, a castle, it was a huge structure that had never appeared in the history of mankind in this world.

It was a miracle, and for many Aborigines, even the miracles of the gods were nothing more amazing than this.

Such architectural marvels could not be hidden, and the Lion Knights now organized daily patrols to stop those who tried to cross the line into the territory of the ancient Roman Empire out of curiosity.

Although the Lion King had ordered the cessation of all hostilities against the Roman Empire, his latest order made it clear that the Lion Knights must do everything in their power to prohibit others from approaching the massive building.

It was only now that it was discovered that the famous Lion Knights of Sarion could have turned the line of defense overnight and became the first line of defense to protect the ancient Roman Empire if the lion king wanted to.

The Plague of Flowers has already broken through the first line of defense set by the Duchy of Sarion, and more than 20,000 defenders have been killed in this battle, and the only good news for humanity is that this time, the Plague of Flowers will not be able to get more supplies from the bodies of the dead.

Many guards would rather douse themselves with fire oil in times of desperation than be infected by the plague of flowers.

In addition to the large amount of supplies supported by the Europa Empire, the unexpected support from the Seris also greatly boosted the morale of the Duchy of Salion.

Despite the fact that the Honor Tournament was held by the Europa and the eventual winner was also a Europa, the entire Old World knew that it was because the Seris stopped playing before the finals.

This game brought the Cyris to fame in the Old World, and when the Cyris steel ships appeared in the harbor, the king of Sarion began to think that his country had been invaded.

But when thousands of heavily armed Seris warriors encamped in the wilderness far from the city, the messengers expressed their wishes with goodwill from afar, the people of Sarion were reassured.

The Seris people came to fight against the Plague of Flowers, and their attendants gave a speech in King's Square, informing everyone that they had come with good intentions, that the Plague of Flowers was the enemy of all mankind, and that there was no difference between nations in the face of the Plague of Flowers, so they were willing to put aside the isolation of the borders and fight against such evil in the name of all mankind.

The natives of the Old World had never heard such a high-level theory before, and in just two days, the king of the Duchy of Sarion realized that if he was unwilling to accept the 'goodwill' of these Serisians, he was afraid that he would already be on the opposite side of the entire Sarionians.

The 'goodwill' of the Seris was transmitted to the country in the most direct way, and in an extremely efficient way, in just two days, the deep military cooperation that used to take months, if not years, was completed.
