The location of the fortress camp that the protagonist finds is a tree stump near the top of a hill.

It was supposed to be a giant tree, big enough for three people to hug together. But now the giant tree no longer has the green shade of the pavilion and the trunk of the giant pillar that connects the sky and the earth.

Due to perennial insect infestation, the inside of this giant tree is so damaged that it can no longer bear its own weight.

On a distant day, perhaps in the bitterly cold winter winds and howling winds, the giant tree broke off from its most fragile part near the ground, and then the huge trunk rolled down the steep slope to the base of the mountain, leaving a stump still standing tenaciously near the summit.

The broken stump may have been taller, but after wind and rain erosion, the top of the stump is now only about half a meter above the ground on average.

The stump's outer skin is still intact, after all, borers don't like the unnutritious bark full of lignin.

However, the inside of the stump is riddled with holes by larvae such as beetles and silverfish. These gnawed passages lead in all directions, similar to ant nests, and can be used as camps with a little modification, eliminating a lot of effort in digging underground nests.

However, there are too many moth-eaten holes in the stump fracture to the outside world, and most of them need to be closed, leaving only a few paths.

Moreover, the fracture of the stump is not a plane, showing an inclined trend, and there are many burrs that stick out abruptly, pointing to the sky.

This rugged surface is not conducive to the formation of the Divine Envoy King Legion, and it is not conducive to bringing out the maximum power of the razor tactic.

Therefore, if this is chosen as a base, the uneven area will also need to be filled with mud and stones.

The most difficult thing about building a garrison fortress under the nose of parasitic ants is how to divide the forces to build a camp and complete the project and put it into use in the shortest possible time.

Building a complete fortress from scratch takes most of the day, according to the protagonist's previous experience in building "Dongyang Castle" and the two fortresses in the south.

It is also a good idea to secretly start work while the parasitic ants are asleep at night. However, the construction speed of the ants also decreases at night, and in the summer, the nights are short, and it takes about a little more than a night.

If the remaining wooden piles were to be used to build the fortress, the excavation of underground nests, the construction of earthen embankments, and the excavation of trenches could be omitted.

The ants only need to use the "concrete" mixed with ant glue and ant droppings to close the hole at the top of the stump, fill in the gaps on the surrounding bark base, and build a defensive belt similar to the earthen embankment platform, the construction difficulty is not high, and the amount of work is greatly reduced.

So in the end, the protagonist chooses this natural stump as the location for the construction of the fortress camp.

In addition to serving as a camp for troops to rest, attack, and stock up, the protagonist also intends to lure parasitic ants to climb long distances to the top of the hill to attack the fortress and deplete the enemy's living forces in a more advantageous defensive battle.

After all, in the defensive battle, the Divine Envoy King Legion had an even greater advantage, and the tall straight stump basically eliminated the threat of silk parasites.

When the parasitic ants have consumed too much strength in the long-term attack, the protagonist is able to lead the army to quickly break through the enemy nest and completely eliminate the threat of the parasitic ants.

In order to ensure that nothing goes wrong, the protagonist repeatedly summons Roll, Lan Bofei and other kings to meet to study the attack plan and work together to improve the details of the plan.

It is not common for the protagonist to include the ordinary king in the formulation of the plan in this way, and the battle meeting of the main nest is generally limited to discussions between the kings, and the ordinary king is only responsible for execution.

However, these kings are not inferior to the big king in intelligence, and they have fought many times with the protagonist, and they are also very experienced in combat. They also provide a lot of useful advice to the protagonist, such as: the number of construction teams and alert troops, the most appropriate level of training, etc.

After the attack plan is decided, the protagonist waits patiently for another two weeks, and finally waits for all the new troops to achieve their training goals.

In the past two weeks, the parasitic ants have finally found a new line of attack, and after rounding the waterhole, they have launched several attacks on the southern fortress.

The veterans of the First Legion of the Divine Envoy King who were guarding here still easily crushed their attack.

Recruits with similar training will also rotate to the southern fortress to accumulate actual combat experience and adapt to defensive operations in battles with small-scale enemy forces.

The pottery bombs produced in the "Dongyang Castle" were continuously moved to the southern fortress, and a large amount of grain was also transported.

Only a small portion of this ration and ammunition was supplied to the defenders of the fort, and most of it was used to prepare for the upcoming attack. For this reason, the underground space of the southern fortress has been expanded a lot, so that it can barely fit this batch of materials.

According to the protagonist's plan, ammunition and rations need to be supplied for at least half a month, so that the attacking troops will have enough time to constantly deplete the enemy's strength.

- I'm the dividing line -

Finally, the day came when the offensive plan was executed.

In the afternoon, while the southern fortress was engaged in a daily defensive battle, a unit hidden not far away, ignoring the parasitic ants that were attacking the friendly forces, bypassed the enemy and marched south under the guidance of the protagonist in the sky.

This force consisted of 500 soldier ants, escorted by the Second Legion of the Divine Messenger King.

After marching for about two hours, they stopped at the midpoint between the southern fortress and the hills.

Subsequently, the workers quickly began to dig underground nests, while building earthen embankments and digging trenches.

It is a staging station that will transport ammunition, rations and recruits to the front line.

Once the front-line stump fortress was put into operation, there was almost no defensive pressure on this side, so the transfer station, although it was also built according to the design of the fortress, was much smaller: there was only about a three-centimeter diameter of open space in the earthen embankment, the earthen embankment was only one decimeter high, and the trench was very shallow.

This small-scale project was built very quickly and was completed before dark.

Subsequently, the large army of the Second Legion of the Divine Envoy King remained behind, and the rest of the worker ants returned to the southern fortress under the escort of ten squads of the legion.

Night fell, but the entire "Dongyang Castle" and the southern fortress were mobilized.

A large number of worker ants are flowing between "Dongyang City" - the southern fortress - the transit station at three o'clock.

The supplies stockpiled in the Southern Fortress were transported to the transit station, while the supplies from Dongyang Castle were continuously transported to the vacated warehouses of the Southern Fortress.

At the same time, the four legions of the Divine Envoy King also began to move on a large scale.

A war of revenge is on the horizon!
