The tired He Jun no longer had the heart to argue with others, so he did not hesitate to turn off the communication, ran to the rooftop with a smoke, got into the all-terrain vehicle, and took over the control of the drone.

Drones in the 23rd century are so powerful that even if no one is in control, they can make subjective judgments based on the detected situation and make a decision on whether to issue an alarm.

But drones are not artificial intelligence after all, and it is already its limit to be able to do this, and the specific situation still needs to be judged by humans.

After He Jun took over the drone, he checked the real-time video for the first time, and saw a large number of light points at the edge of the map, which were the light points that represented people!

The distance between the point of light and the small city is at most five or six kilometers.

The strange thing is that these points of light are all gathered in small groups, not far from each other, arranged in a sinuous and twisted line.

This kind of marching column is very strange, He Jun switched the display mode to take a closer look, and was stunned to find that these points of light did not appear on the road south of the city, but appeared on the river, and took a warship to go upstream!

He Jun suddenly realized, no wonder the light spots were all in groups.

Looking at the dark city again, He Jun couldn't help but sink to the ground.

Are the Leather Giant's sentinels scheduled to the waterway?

He Jun really wanted to send a message to the leather armor giant, so that the two sides could fight another big battle under the city, so it would not be strange for Sensei to delay it for another two days, ten days and half a month.

But the armored giants didn't know what technology they used, and the ships went upriver without slowing down, and in ten minutes or so, the fleet could reach the city.

And the straight-line distance between him and the small town is more than twenty kilometers. Unless it is flying, it can rush to the small town in time to call the police......

That's right. Drone!

He Jun's eyes lit up, and he controlled the drone to reduce the altitude. Scan the city for the location of the Thundercrack.

UAVs can only look for living creatures through thermal imaging, but they cannot determine the specific identity of the target through thermal imaging. However, this is not difficult for He Jun, the small city is so big, since it occupies the small city, Lei Crack and other high-level personnel will definitely not sleep on the streets, and eighty percent will live in the best buildings in the city.

Thermal imaging can't tell whether the building is good or bad, but such a group of people with special identities must be indispensable to the guards. So he directly selected the building that guarded the most.

The drone quickly lowered its altitude and switched to the ordinary night vision lens to look for the traces of the thunderbolt, but everyone was sleeping, and it was impossible to tell who was who.

What can I do?

He Jun suddenly slapped his forehead, thinking about it, it didn't matter where the thunder crack was, the old boy didn't recognize the drone, and when he saw the drone, he didn't know that this was warning him.

Since there are sentinels on the city walls. Wouldn't it be enough to just let the sentinels discover the incoming fleet?

Thinking of this, He Jun immediately controlled the drone to fly up the city wall, and randomly found a sentry close to the river, and flew in front of his eyes.

At this time, the morning light had already revealed the sky, although the sky was not yet bright. But it didn't affect the vision much, and the sentry immediately spotted the drone close at hand, thinking that what was flying in front of him was a bird or something. But the drone suddenly stopped, allowing him to see clearly.

The Sentinel discovers that a pitch-black saucer is capable of floating in the air. Immediately let out an exclamation and tried to stab the thing down with the spear in his hand.

He Jun hurriedly controlled the drone to avoid it. Slid sideways, flying right between the sentry and the fleet.

When the sentry's gaze focused on the drone again, He Jun moved his fingers, and the drone flew towards the fleet at an extremely high speed and quickly pulled up.

The sentry's gaze followed the drone, and when the drone disappeared, his gaze landed on the river in the distance, and at the same time fell on the still thick and low-key riverboat in his eyes.

The panicked sentinel no longer bothered to look for the drone, and with a loud roar, he ran quickly towards the bell tower, and a moment later, the bell rang throughout the city.

The soldiers, who had slept for only a few hours, got up sleepily, and those who were so tired were either called up by their comrades or kicked up by the officers, in short, the troops of the whole city were assembled in the shortest possible time, and they climbed the walls one by one.

The narrow walls could not accommodate so many warriors, so only the walls near the river were manned, and the others were scattered throughout the city, bows and swords unsheathed, and the whole city was slaughtered.

Finding that the city was already on guard, and the fleet was no longer concealed, a row of wide oars stretched out on both sides at the same time, and the speed that had not been slow increased again, and after a while, it stopped on the river not far from the small city.

The fleet did not rush to attack, but waited for the arrival of the following ships, and when all the ships were lined up on the water, they lifted the veil on the side of the ship, revealing the huge wooden frame that was placed on the side of the ship.

When He Jun's eyes saw the wooden frame on the ship through the lens of the drone, he subconsciously shouted: "Ballista!" ”

This thing is much more advanced than the trebuchet, and the leather-armored giants on the city walls don't seem to know anything about this weapon, and they don't even have the slightest intention of dodging.

As expected, a few minutes later, the first volley hit the head of the city with unmistakable accuracy, and the soldiers on the walls were knocked down by the stone bullets that spread out of the ground.

This is just the beginning, after several waves of stone bullets in a row, more than half of the leather armored giants on the city have been damaged!

Immediately, the flotilla firepower extended to the city, and even the troops gathered in the city were in trouble, and the city was in chaos for a while.

The leather giants were not beaten back, and some of the officers immediately organized their men to use the trebuchets captured in the city to launch a counterattack.

However, whether it is a ballista or a trebuchet, you must have a certain amount of knowledge to hit accurately, but the leather armor giant lacks not a little bit in this regard, all the stones are smashed into the river, and it does not threaten the safety of the ship at all, but provokes more fierce retaliation from the fleet, and in the blink of an eye, those trebuchets are smashed into pieces of wood by the ballista.

He Jun, who witnessed this scene, was full of emotion, and he didn't need to look at him to know that the small city that fell into the hands of the leather armor giant was about to return to the hands of the armor giant before it was warmed up.

Unwilling to be defeated, the leather-armored giants fought to the death, and batch after batch of warriors were sent to the city wall, and then they were smashed down by the rain of stones.

When the sun rose, the leather giants no longer sent men to the city walls, but scattered their men in the city, repairing the walls while waiting for the enemy to attack the city.

But the fleet in the river was not in a hurry at all, since the enemy could not be seen from the wall, they simply stopped the attack, and when they saw the figure, they smashed it a few more times.

The Thundercrack in the city kept speculating about the purpose of the armored giants, and while they didn't come up with any useful answers, the enemy certainly had bad intentions. (To be continued.) )
