However, the night sentry of Island 5399, although it found the island attack team that wanted to sneak into Island 5399, and the other deep seas that received the night sentry alert, also stopped the island attack team in time, but it was still too late.

When discovered by the night sentinels, the siege team that had already infiltrated less than three kilometers away from Island 5399 immediately used [Instant Advance] to start charging towards Island 5399 after realizing that their infiltration had been discovered.

Although this wave of charge, due to the blockage of the island's deep-sea garrison, it could not rush to the end, but the island attack team that was forced to stop had already rushed to a place more than a kilometer away from Island 5399 at this time.

It's more than a kilometer, even if it's an ordinary person, it won't take long to walk this distance, let alone the ship's mother. Therefore, even if the deep-sea garrison on Island 5399 is very timely to attack the island, it is already powerless.

I saw that the speed was the fastest, and soon after using the [instantaneous advance], it quickly broke away from the large army, and when it was blocked by the deep-sea garrison on the 5399 island, and had no choice but to stop, the fireflies and Z1, which were only more than 500 meters away from the 5399 island, quickly approached the 5399 island while moving around to avoid the shelling.

Even though the deep-sea garrison on Island 5399 tried desperately to stop it, the dexterity and agility of the Fireflies and Z1, and the distance of only 500 meters, made their deterrence pale in their deterrence.

Eventually, in the fifth minute of the official start of the war, the Fireflies rushed to the beachhead of Island 5399 with Z1.

At this time, in the forest that was originally scattered on the beachhead, relying on the cover of trees, to avoid the attack of the island attack team, and cooperating with the night sentry to block the two deep-sea teams of the island attack team, they immediately divided into a team and continued to block the fireflies and Z1 who rushed to the beachhead, wanting to suffocate the fireflies and Z1 on the beachhead.

It's a pity that unlike when attacking Island 5215, after the lessons of Island 5215, they have gained a lot of experience, and Firefly and Z1, who have matured further, did not show the slightest panic in the face of the prevention of this deep-sea team. On the contrary, the two ship girls, who were extremely calm, immediately resisted and dodged the attack of the deep-sea team in accordance with the strategy plan formulated by Zuo Tianyou in advance, and quickly rushed out of the beachhead and into the forest where the deep-sea team was located.

After rushing into the forest, Firefly and Z1 did not entangle with the deep-sea team more, but continued to follow the strategy plan formulated by Zuo Tianyou in advance, while avoiding the encirclement and interception of the deep-sea team, while rushing towards the night sentry at the back of the forest - even with their strength, it would not take much time to eliminate this deep-sea team.

Under the decisive disposal of Firefly and Z1, the deep-sea team that had been smashed by wishful thinking instantly became chaotic, and at this moment they were in a dilemma. Because obviously, the Fireflies and Z1 are now trying to force them to make a choice - I'm going to kill the night sentry, if you don't come to chase it, if you come to chase it, there is only a small team left on this side of the beach, and in the face of a large force of island attack teams that are comparable to you, with your strength star, don't want to hinder the landing of the large army at all.

If you don't chase it, then dare to be kind, even if the old lady can't kill the night sentry quickly, she can harass the night sentry, so that the night sentry can't stop the large force of the island siege team with all its might. At that time, the large army will be able to easily approach Island 5399.

Faced with these two dilemmas, in the end, the deep-sea team still did not choose to pursue the fireflies and the Z1 - the large force of the island attack team, which was too close to Island 5399, and it was impossible to prevent the large force from approaching Island 5399.

In this case, instead of choosing to divide the troops to help the outpost and prevent the large force of the island attack team from approaching, it is better to choose to stand still, block the large force of the landing island attack team on the beachhead, and drag it until the reinforcements arrive.

So, without the pursuit of the deep-sea team, the firefly and Z1 made a very smooth way through the forest and came to the south of the island, near a hillside dozens of meters high.

And the top of this hillside is the place where the night sentry of the deep sea, or the sentry is located, and it and a seventy or eighty meter high slope to the north of the island constitute the two commanding heights of Island 5399.

With these two commanding heights, the deep-sea defenders on Island 5399 can not only monitor the wind and grass around Island 5399, but also easily block all enemies close to Island 5399.

To be honest, if it weren't for the limited area of the two commanding heights and the small number of deep-sea that could be accommodated, even if hundreds or thousands of enemies attacked, the deep-sea defenders on Island 5399 would not be afraid at all.

It's a pity that if it's just if, the reality is that the commanding heights in the north are okay and can accommodate twenty or thirty deep seas, while the commanding heights in the south can only accommodate the deep sea that is less than one team. Of course, it's not that you can't accommodate more deep sea, if you want a bunch of deep sea to be crammed together, and a random shell can blow up a bunch of deep sea.

At the same time, due to the existence of the southern slope and the distance, the southern beach has become a blind spot for the northern slope, resulting in the northern slope being able to strike only the enemy in the east, west, and north directions. Therefore, the southern side can be said to be the weak point of the defense of Island 5399.

And Zuo Tianyou, who has collected countless information about Island 5399, keenly discovered this weak point in defense, and did not hesitate to use it when formulating a plan to attack Island 5399.

However, the deep-sea side is not stupid, knowing that the defensive strength of the southern side is indeed much lower than the other three sides, so two deep-sea teams are specially stationed here, so that they can cooperate with the sentry posts on the southern slope to block the enemy who is trying to approach Island 5399 from the south.

Ahem, speaking of which, it is also Island 5399, this kind of "local tyrant" island with a large number of deep-sea (three full-scale deep-sea squadrons) stationed, can put on such a big battle, those islands where there are only one or two full-sea deep-sea squadrons stationed, where are there so many troops to give you four assignments.

After coming to the vicinity of the southern hillside, Firefly and Z1 discussed in a low voice, and then decisively divided into two ways, came to the blind spot of the deep-sea sentry on the two hillsides, and began to carry out a unilateral cross-attack on the deep-sea sentry on the hillside.

In the face of the one-sided attack of the fireflies and Z1, the sentry composed of eight deep seas on the hillside was unwilling to be beaten passively, and immediately separated into four deep seas and ran down the hillside, trying to entangle the fireflies and Z1.

As for the remaining four deep seas, they will continue to block the large forces of the island attack team that is less than 300 meters away from Island 5399. (To be continued.) )
