Their arrows never miss, and every shot brings down a monster, able to penetrate each monster's head.

After a siege defense, a single Greenfield Knight can easily achieve thirty to forty kills!

After the border outpost battle, Su Li's reputation soared, and two Greenfield Knights came to Heisen Castle, voluntarily asking to join the legion, to help Su Li fight against the Green Tide and promote the Goddess's teachings.

Su Li also eagerly discussed with them briefly about the insights of defending a city with a bow and arrow.

After all, charging into thousands of monsters on horseback is not a bravery Su Li possesses, nor does he find it necessary.

But in the tower, finding a suitable angle to shoot at soldiers attacking the city from the flank, he is quite willing to do.

He feels the probability of hitting is quite high when aiming at the opponent's head from a distance of several tens or even a dozen meters.

Therefore, Su Li cares greatly about the wall fortifications, walking through the stone corridor; after inspecting, Su Li asked Engineering Master Kurgan: "Is the construction of the castle's defensive facilities complete?"

Kurgan immediately patted his chest and assured: "Lord, please rest assured. The defensive facilities of the castle have been repaired and are ready for use at any time. If the claws of the Green Dragon come to attack the city now, they will crash against these impregnable defenses. The later they come, the more severe the injuries they will suffer!"

Su Li nodded in satisfaction. After the border outpost battle, Su Li had a very direct understanding of the strength of the trench and stronghold tactics.

If a race has thousands of years of combat experience, it must be extremely skilled in building warfare fortifications.

No matter what race the opponent is, as long as they adhere to the laws of physics and cannot instantly destroy an army, constructing fortifications is one of the best tactics to greatly enhance one's tactical advantage.

Kurgan continued to introduce with excitement: "Moreover, our fortress has a very comprehensive defense system, not only walls and towers. We have shooting holes set up on the walls that can maximize the power of our Dwarves and Archer Corps. As long as the monsters attack the city, they will face the continuous onslaught of hundreds or even thousands of arrows."

"Additionally, our fortress is built against the mountain, with three layers of defensive walls tiered like steps. Each wall has a foundation of six or seven meters below it and a moat nearly ten meters wide. Even if the monsters break through the first line of defense and enter the castle, they will be shot down from above by arrows on the second line of defense. Crossing the open space and moats between the walls is like a suicidal slaughterhouse for them!"

This effect finally satisfied Su Li. With three layers of defenses, the combined height of the walls is actually 48 meters, and with the foundation, it's over 50 meters.

What does 50 meters mean? It's almost double the height of a Divine Chosen Knight; for monsters to attack such an imposing barrier upwards, if their eyesight is slightly poor, they can't see the blurry figures of humans on the arrow towers and walls. Meanwhile, human arrows can easily pierce their bodies.

To find a more precise comparison, the flagship castle of the Saxon Elector, King's Castle, has a fortress height of 53 meters, considered the highest mountain-top fortress on Earth.

Su Li's Heisen Castle is close to matching the highest fortress from the Middle Ages.

However, the Saxon's King's Castle is 53 meters high in a single layer, while Su Li's Heisen Castle achieves over 50 meters with three layers combined.

Therefore, Heisen Castle obviously still has much potential for further reinforcement and elevation.

In the future, if Su Li is fortunate enough to encounter a Peak Spirit type of Essence of Nature, it could even help to raise this low mountain under Heisen Castle a few more notches.

This low mountain is still somewhat lacking in height, with the highest peak just over 200 meters, and the foothill regions are flat and fertile.

Although the foothills have the typical undulating terrain, the terrain is not rugged; on the contrary, even the undulating foothills form vast plains.

No residential facilities are allowed to be built within thousands of acres near Su Li's Heisen Castle. It's his exclusive estate territory, where patches of red maple, oak, beech, and walnut trees adorn the broad foothill plains. In the distance, one can see rolling hills and wide valleys, with a few patches of blue ponds and clear rivers and streams dotting the expansive plains.

It can be said that the scenery here is breathtakingly beautiful, especially now in autumn, with the fragrance of osmanthus flowers and hills covered in red leaves. The wide valleys and gentle foothills are planted with various precious fruits, and herds of deer and griffins wander nearby, filled with the joy of harvest everywhere.

If it weren't for the threat of the Green Dragon, Su Li's life should have been perfect and tranquil.

Every day, he could hear auntie's stories from the Half-Elves and unlock some novel positions, then return to the estate to try them out with Hilude and Ingrid.

The Half-Elves' innate intimacy and traditional custom of a family living in a single bedroom always provide abundant knowledge and insights in certain aspects.

In his past life, Su Li, a devoted servant, has slowly found the joy and pleasure of being a Lord in this life.

He is tireless in the knowledge of various Knight practices!

Various powerful cultivation techniques, like the Electric Poison Dragon Drill and Ice and Fire Two Realms, have captivated him endlessly.

What is it like to have a girlfriend willing to serve her lover wholeheartedly? Su Li now finally understands.
