After the end of the poor and boring winter, in this rich spring, the ants have little to worry about food.

However, there are many things that the protagonist needs to worry about.

Because with the arrival of spring, according to the plan drawn up by the Great King's Conference last fall, as long as it is fully implemented, then the offensive and defensive trend between the big-headed ant kingdom and the paving ant barbarians will be reversed. This is a big deal for both ant kingdoms and two races.

The protagonist has already sent a messenger to contact the other side nests and "Dongyang City", but there has been no reply yet.

Before receiving new information, the protagonist can only make his own preparations.

With a small group of worker ants, he climbed the suspended rope bridge again.

Due to a spring rain two days ago, the rope bridge looked a little slippery, and the big-headed ants clung to the exposed fibers of the rough hemp rope under them to avoid falling into the river.

Now, the river has thawed, and the river flows slowly but surely eastward, and the corpses of water spiders and big-headed ants that had been frozen in the ice have completely disappeared into the waves.

On the surface of the river, some insects that need to use water to reproduce fly and wander nearby, and water spiders tread the water dexterously, not pointing a circle of ripples on the water surface, and the protagonist can't help but envy their ability to float.

If the big-headed ant could still have half of its life if it fell off the rope bridge, then now falling into the river is a situation of nine deaths. Flowing currents can sweep people overboard, and there are countless predators on and in the river – water spiders, dragon lice and water bugs.

I don't know if it's due to precipitation, or if the hemp rope is heavier after being wet by water, the protagonist feels that the height of the river is now lower from the rope bridge.

The protagonist and his big-headed ants successfully crossed the rope bridge and came to the north bank of the river again.

It's also a vibrant place, with all kinds of insects and plants enjoying the beginning of spring.

However, unlike the South Shore, the protagonist has not seen ants active in this area, as there is no secondary nest of paving ant barbarians in a small area nearby. The protagonist estimates that it has just passed the winter, and the paver ants are also searching for food near the nest, so they should not come all the way to the river in a short time.

This is good news, the protagonist needs to use this time to build a fortress at the bridgehead on the north bank of the river, and drive a wedge in enemy territory.

This is a plan that has been made before, if the plan goes well, from now on, the big-headed ant kingdom will have to defend passively every winter, and then invest a large number of troops and materials in the spring to recover the lost territory, and the situation will be greatly improved.

The previous plan also included the construction of a pontoon bridge, but the protagonist has already taken advantage of the favorable winter period to change the pontoon bridge into a suspended rope bridge, and the construction is in place. Now all you need to do is build a bridgehead fortress.

The protagonist leads the team to the bridgehead that was dug last winter, just north of the tall tree.

The tall tree has not yet germinated young leaves, and the protagonist still does not know its variety.

At the base of the tree, the protagonist can't find a hole in the site last year, and judging by the mess on the ground, there must have been a small waterlogging during the snowmelt and rainfall.

The dirt is mostly dry now, but it looks like the little nest has been washed away. The protagonist shook his head and led everyone to start work again.

A messenger was sent back to the "Waterfront City", and soon after, the "Waterfront City" garrison was sent to the construction site on the north bank of the river to carry out the construction. The Fourth Legion of the Divine Envoy King followed, and they set up a wide range of cordons nearby, ready to strangle the paving ants that inadvertently intruded into the area.

Time, the protagonist needs at least a week to build bridgehead fortresses, stock up on supplies, and mobilize troops. But he was not sure if he would be able to keep the enemy from alarming for a week.

- I'm the dividing line -

The construction of the bridgehead fortress has been started for three days, and the building structure has been basically completed.

This is a fortress that is customary to the legions of the Divine Envoy King, and the structure is very similar to the structure of the southern fortress of "Dongyang Castle".

The fortress is located on the north side of the roots of the trunks of tall trees, and the ground is high, surrounded by a circular clearing surrounded by a concrete wall about one decimeter in diameter.

There were moats and drainage ditches outside the city walls, and drainage holes at the base of the city walls connected to the moats outside the city.

The open space within the city walls was where the army gathered, and the highest point in the middle was the entrance and exit of the underground lair. An ant seal was piled up at the entrance and exit to enhance the waterproof ability of the entrance.

The underground part is built as a standard ant nest, deep into the land, avoiding the intricacies of tree roots, with warehouses, nurseries, queen dormitories and dormitories, and the big-headed ants even collect white pebbles from the river bank to lay a small meeting room.

There is also a combustion chamber, which is traditionally arranged in the middle of the deepest part, and the exhaust port passes through the nest, which can significantly increase the temperature of the nest when the flame is burning.

Overall, this is a small fortress, which can accommodate about three or four thousand big-headed ants, and supplies to support half a year. Fortunately, such a fortress has been tested and is able to hinder the use of an enemy with numerical superiority and achieve long-term entrenchment.

After the "bridgehead" was built, in the next few days, a steady stream of fire, fuel and grain was transported from the "waterfront city", and the combustion chamber of the "bridgehead" was quickly put into use, and the granaries and material warehouses were quickly filled.

However, this kind of transportation also comes at a great cost, and every day the transported ants accidentally fall into the river, and most of them are never found.

In this regard, the protagonist can only try to avoid transporting it when the wind is strong, and then accept this loss.

In addition, the protagonist reduces the volume of transport. The Fourth Legion of the Divine Envoy King officially moved in as a "bridgehead" defender, and then scavenged for food and supplies in the vicinity on its own, avoiding relying too much on the fragile rope bridge transportation lines.

Fortunately, the Divine Envoy King's legion, which was building on the north bank of the river, did not encounter an army of paving ants, and the few paving ants that had strayed into the vicinity were quickly killed by the defenders who were waiting for them.

And the paving ant barbarians obviously haven't smelled anything different from the missing people, after all, it's normal for ants to disappear, but although they are the most civilized race in this world, they still have many natural enemies, and a single ant is not the opponent of these fierce natural enemies.

Just like primitive humans have long been acting alone, they also have to face the threat of fierce beasts. And with the expansion of the team, whether it is primitive people or ants, their strength will be greatly enhanced, and they will no longer be afraid of savage beasts.

There's also new news that some of the messengers sent out have returned!
