In the next few days, Yiren's actions made Luo Ji clearly realize that his consumption must have had an effect, and the other party could no longer sit still.

The Flügel legion launched a direct attack on them from the air, leaving the Elephant giant artillery unit's safe output environment forever gone.

But at the same time, Luo Ji could also feel that the opponent's attack was not strong, and they were simply trying to contain them, without any intention of fighting him head-on.

Faced with this situation, Luo Ji naturally took advantage of it.

Fighting a small-scale war of attrition based on the recovery ability of his orc army? His orc army is simply equivalent to a perpetual motion machine. Who is afraid of whom?

After waiting for the army on the front battlefield to attract enough attention from the opposite side, Luo Ji's other army hidden in the dark also quietly launched its operation under the cover of night...

The border line is about three hundred kilometers northwest. According to Salir, this is the fortress with the weakest garrison on the border of the Yiren civilization.

The terrain plays a big role here.

The fortress is built on a rugged and difficult mountainous area. The army and some land vehicles cannot pass through here at all, so the garrison force does not need too many.

Of course, the more important reason is that the Yi people's civilization construction capabilities are limited. On this kind of terrain, it is difficult for them to build any large-scale fortress. A small fortress has only so much internal living space. No matter how many troops it has, it can't accommodate

No more.

On weekdays, only about five hundred troops are stationed inside this small mountain fortress.

During the war, the number of troops should be appropriately increased. There may be 800 to 1,000 people, and no more than 1,200 people can be killed. If it goes up, it will be impossible to squeeze no matter how hard it is, and it will only become a burden in the end.

Outside the fortress, an army quietly approached at two o'clock in the morning.

The Yiren civilization obviously does not have electrical equipment. It still uses firelight for lighting. Those with better conditions will use holy light stones. To put it bluntly, they are some stones blessed by the power of faith. After dark, they will emit pure white light, and the lighting effect

Much better than torches, candles, or oil lamps.

The backward lighting equipment makes this mountain fortress' security capabilities seem a bit low at night.

Several agile black shadows quickly approached.

The Yiren civilization with limited construction capabilities built fortresses on such mountainous areas. It was often impossible to build the fortress walls too high. According to the terrain and environment, the shortest part was only about ten meters.

Holding his breath and listening to the sound of the patrol's falling steps above the fortress, a soldier carefully took out a cylindrical object with a diameter of three centimeters and a length of only about five centimeters from the pocket behind him, and then pressed it lightly

A button was located on the side of the cylinder, and with a quick pull, the five-centimeter cylindrical object immediately stretched out.

At this time, a simple visual inspection showed that the length of the cylinder after stretching was at least about 30 centimeters, almost turning into a decent-looking short stick.

However, this short stick was obviously not used for attacking. The figure pulled out a stopper from one end of the short stick, then raised it above his head. After raising it to a maximum height, he pressed one end directly.

On top of the high walls of the fortress.

The inside of the short stick is actually hollow, and it is filled with a large amount of special mucus. This mucus will quickly solidify in a short period of time after contacting air or other substances.

In other words, this special mucus can firmly stick this short stick to the wall of the fortress.

And during this whole process, almost no sound is made.

Maintaining the pressed position, after about three seconds, the figure stopped, and then tried to break the short stick with force to ensure that the short stick was firmly stuck.

Then, I saw him holding the short stick with both hands, making a posture like carrying a horizontal bar. With a sway, his feet were already firmly stepping on the short stick without any sound.

.

Next, he repeated the previous operation, using three short sticks in total, allowing him to get completely close to the target.

At this moment, the figure maintained a crouching posture, squatting on the short stick he had fixed at the end, hiding in the shadow of the outer barrier.

It is no exaggeration to say that in this position, as long as he stood up a little, the wingman soldier standing above might notice his presence.

There was no rush to take action, he was waiting.

On top of the fortress, in addition to the winged soldiers standing guard, there are also several winged teams responsible for night patrols passing by.

As the footsteps approached, he, who had received professional training, pressed himself against the outside wall. Just by listening to the sound, he could tell where the patrol team was.

When the wingman soldier walking at the end of the patrol team also passed behind the soldier on guard, and the moment both sides were completely out of each other's sight, he moved!

The wingman soldier on guard didn't even have time to react. A dagger with a blade completely painted black slit his throat. After quickly taking away a life, he jumped onto the fortress.

He was as light as a swallow, and his footsteps landed on the ground without even making a sound. He held the body with both hands at the same time and gently placed it on the ground. This whole set of actions only took one second.

At the same time, in the darkness in the distance, under the cover of the night wind, four sharp arrows flew over quickly, and the four members of the patrol team were instantly killed by precise snipers.

The Wingman soldiers standing guard are twenty meters apart from each other. The soldiers in the patrol team will pass by here every thirty seconds, and his current position is a visual blind spot around the corner.

Before passing the corner, other wingmen soldiers could not see what was happening here.

But once the corpses of these soldiers fall to the ground and make noise, they cannot be concealed.

Seeing that the four corpses that had been shot at extremely high speeds were about to fall to the ground.

At the critical moment, the soldier who had already jumped onto the fortress rushed forward, used his whole body to hold all four corpses at the critical moment, and then gently put them down.

And only three seconds have passed since he killed a soldier on guard and jumped onto the fortress!

Under the flickering firelight, a vigorous figure was reflected.

The night vision goggles and special black mask worn on his face made it impossible to see his face clearly, but the pointed ears protruding from the hat were the same as the ones that flew over and accurately shot four winged soldiers.

The arrows proved their identities. These were the troops of the elves!
