At noon today.

  Hundreds of demons suddenly appeared in the river bay area.

  They were destroying and killing everywhere.

  Several vilges were in attacked, completely sughtered by the demons.

  Fortunately, these demons were retively low-level demon races.

  Their strength was average.

  After paying a certain price, the nobles in the river bay area successfully exterminated them.

  However, although these demons were dead, the impact they brought has not disappeared.

  The perceptive nobles have already sensed that something is wrong.

  Under normal circumstances.

  It is impossible for the Rond Continent to have such a rge group of demons coming out of nowhere all of the sudden.

  Unless there are demon worshippers opening demon portals, or there are dimensional rifts leading to the Abyssal pne.

  Regardless of which one, it means that more demons could come out of the bottomless abyss at any given time.

  That's why.

  The atmosphere in the river bay area is quite tense.

  And in the neighboring Rhine region, it is naturally impossible to remain unaffected.

  Many intelligent nobles have already started hoarding food, buying weapons, and expanding their family's armed forces.

  Habsburg Manor.

  In the study room.

  "It seems that the information about the demonic disaster is most likely true."

  Looking at the intelligence collected and summarized by the Shadow Organization, Rennes also felt a strong sense of urgency.

  If a demonic disaster really occurs.

  The demons appearing in the river bay area will definitely increase.

  By then, the Rhine region will probably not be spared.

  A catastrophe is indeed about to come.

  "It seems like I must speed up and make thorough preparations."

  Rennes thought to himself.

  To stop the demonic disaster, he naturally doesn't have the ability to do so.

  But he must ensure that his wives, children, and territory are safe.

  To achieve this, he must continue to greatly strengthen the defensive forces of the territory.

  However, it is definitely unrealistic to achieve this goal by significantly increasing the armed forces of the family.

  After all, the cultivation of extraordinary individuals takes years.

  As for mortal armies, they are useless in the face of the demonic disaster.

  They are simply sending themselves to their deaths.

  "It seems that the only way to enhance the defensive strength of the territory is through other means."

  After pondering for a moment, Rennes quickly came up with an idea.

  First, he needs to quickly grasp the manufacturing process of the magic crystal cannon and produce a rge number of them as city defense weapons.

  Second, he will use his recently acquired expertise in advanced magic arrays to set up defensive magic arrays in major cities.

  Third, he will continue to thicken and raise the walls of various cities.

  "The acquisition of strategic supplies such as food cannot be stopped. Each town needs to establish strategic reserves to prevent being besieged by the demonic army and running out of ammunition and food."

  Rennes wrote down these pns on parchment one by one.

  The procurement of food and the strengthening of city walls do not require his personal attention and can be delegated to his subordinates.

  However, the production of magic crystal cannons and the arrangement of defensive magic arrays must be personally handled by him.

  After all, he is the only one in the Habsburg family who understands advanced magic arrays.

  After finalizing the work pn, Rennes entrusted the house affairs to Janice.

  He began to seclude himself and tackle the difficult task of manufacturing the magic crystal cannons.

  One month ter, with Rennes and numerous military bcksmiths working tirelessly, the first magic crystal cannon was finally successfully manufactured.

  After a simple test, the data of this magic crystal cannon came out.

  Its maximum range is about fifteen kilometers.

  As for the power, it is limited by the problem of insufficient material strength.

  Even if enough magic crystals are filled, it can only produce an attack power equivalent to a five level magic spell. (Equivalent to a full-force strike from a 13th-tier mage).

  Any higher and it would explode.

  As for consumption, taking the maximum output power as an example, each shot requires filling with magic crystals worth tens of thousands.

  It's like a gold-devouring beast.

  With the current Habsburg family's reserves of magic crystals, Rennes was afraid they will be depleted after a few hundred shots.

  Rennes directly added magic crystals to the procurement list.

  To increase the "ammunition" reserves.

  At the same time, a rge quantity of materials for manufacturing magic crystal cannons were purchased.

  Mass production of magic crystal cannons began.

  The manufacturing cost of one magic crystal cannon is around 500,000 gold coins.

  Although it is somewhat expensive, the Habsburg family's financial resources can still afford it.

  He pns to start with a hundred cannons and turn all the cities in his territory into fortresses.

  Just as Rennes was busy,

  Baron of the Bck's family, Bennett, suddenly came to visit.

  Bennett is the brother of his wife, Katie, and Charlene.

  Therefore, Rennes couldn't refuse to see him.

  There was no other way, he had to temporarily put down what he was doing and walked towards the reception room.

  As soon as he entered, Rennes saw Bennett sitting in a chair waiting.

  It has been several decades since Rennes rescued the Bck family and killed the projection of the scarlet demon god.

  Time waits for no one.

  So many years have passed.

  Bennett has already transformed from a handsome young man into a middle-aged man with a big belly.

  "I have seen Duke Rennes."

  Seeing Rennes enter, Bennett quickly stood up to greet him.

  "Lord Bennett, do you have any business coming here today?"

  After a brief exchange of pleasantries, Rennes went straight to the point.

  A camity is approaching.

  There are many things he needed to do.

  So there is no time to waste on idle talk.

  "I came here this time to ask you to sell a batch of high-quality weapons and city defense equipment to us."

  "Not long ago, the Great Demon appeared in the River Bay Area, and I believe you are aware of it."

  Upon hearing this, Bennett directly expined his request.

  Nowadays, due to the appearance of demons, the situation was quite tense, and the nobles in the Rhine region were all garrisoning troops.

  The market has long been swept clean of high-quality weapons and city defense equipment.

  The Bck family simply cannot purchase enough weapons to protect themselves, like those Strong noble families armed forces.

  Therefore, he hoped that Rennes can sell a batch of high-quality weapons and city defense equipment to the Bck family, considering their alliance retionship.

  "Okay."

  After pondering for a moment, Rennes agreed to it.

  Due to early preparations and hoarding.

  The Habsburg family had an abundance of high-quality weapons.

  In addition, with the mass production of the magic crystal cannons, some of the city defense armaments were no longer needed.

  Selling a batch to the Bck family would not have much impact.

  "Thank you very much, Duke Rennes."

  Upon hearing Rennes' prompt agreement, Joy on Bennett's face was filled with excitement and gratitude.

  He once again was proud of his wise decision decades ago.

  Fortunately, he had foresight and married his two sisters to Rennes.

  Establishing a solid alliance.

  Otherwise, how could the Bck family now receive the weapon support from the Habsburg family?

  After a discussion.

  Rennes sold fifty Wind Chaser Crossbows, five hundred Fine Steel Great swords, and five Bursting City Crossbows to Bennett at a discounted price of three million gold coins.

  With a satisfied smile, Bennett left the Habsburg Manor.

  After seeing off Bennett, Rennes once again devoted his energy to the mass production pn of the magic crystal cannons.
