The high-end fence connecting the corridor extends out and is built in a square, with a length and width of 100 meters, and the front of the square has spacious openings.

100 meters is also calculated, which is exactly the crossfire range of crossbow arrows.

The high-end fence was quickly built. Luo Yu removed all the automatic crossbow arrows from the south and installed them on the walls on the left and right sides of the square strike array.

There are exactly 17 automatic crossbow arrows on one side.

Such a placement not only allows cross-fire strikes on enemies coming out of the corridor, but also allows fire to cover enemies that escape from the strike array.

There are 17 crossbow arrows on each side, and a wave of scattered shots is really a life-threatening one.

In this way, the strike array is basically completed.

The strike array cannot be completely closed. When it comes out of the corridor, there is a clearing on the front and the direction to the territory.

Luo Yu would not block this road, should he still go?

Moreover, completely blocking it with a wall is not conducive to subsequent construction and firepower attacked from the territory.

Later, I plan to build high-performance defensive weapons such as lightning towers and flamethrow towers, which are extremely accurate and have a long range.

Therefore, the front cannot be completely blocked with the wall!

But such an open front is not good, so Luo Yu clicked on the defensive building to build a wooden horse.

A row of wooden horses directly blocked the front, but not all of them were blocked. The two ends of the wooden horses connecting the high-end fences were opened with two small mouths of 2 meters for people to pass through.

These two small mouths allow animals to transport corpses, and Luo Yu is also convenient for collecting spoils.

Of course, the opponent can also rush out of the strike formation through these two small holes, but how could Luo Yu leave such an obvious flaw?

He built a row of half-man-high sandbags behind a row of wooden horses. He and Xiao Jin and Xiao Kong could hide behind the sandbags and hold bows and arrows and slingshots, shooting like a row of bunkers.

Let’s fight those guys who may rush out of the strike formation first!

In this way, you and the animals can also participate in defense. It is difficult to obtain attribute points now, and the probability of obtaining attribute points you participate in the battle is higher.

The sandbag is built and the strike array is truly completed!

But Luo Yu was not at ease. He built two automatic crossbow arrows at the two exits behind the sandbag. These two crossbow arrows cannot attack the frontal enemy due to angle problems. However, once someone really rushed out of the strike array from the small intersection, they would be shot from behind by hidden crossbow arrows.

The plots that follow are often fatal.

If the strike formation really cannot block the enemy, these two crossbow arrows can also make the opponent spend some time destroying it, so that Luo Yu and the little cuties behind the sandbag have time to withdraw into the wall of the main base and launch the second round of defense.

Perfect!

Looking at the winding but majestic strike array in front, Luo Yu felt invincible!

Luo Yu felt that his attack formation was even better than the Bagua formation...

As I said, practice is the only way to test the truth. Luo Yu was happy and prepared to summon a wave of attacks.

Because there are too many flies now, the use of special milk to summon attacks will be eaten up by the flies first, so he decided to use the [Random Attack Summoner]

【Random Attack Summoner, Current Number: 2/3】

"Wait a minute, if I use a hundred times critical strike, will it increase the attack intensity by 100 times?"

Luo Yu had a sudden whim, but the moment this idea came out, he suppressed it.

It's so terrible. If you really summon a large attack of tens of thousands of people, you may not be able to withstand the attack formation at this stage.

In order to better observe the operation of the strike array, Luo Yu built another watchtower after the row of sandbags.

He stood on the watchtower and chose to use the random attack summoner.

【You are using the random attack summoner and are selecting the random difficulty for you】

【Unfortunately, you have drawn an extremely difficult attack, and the difficulty will be 4 times that of an ordinary attack】

[Tip: In order to retaliate against you, the prince of the Skasa tribe is leading a large number of tribal warriors to attack. The attack arrives: 2 hours, please be prepared]

It's only two hours away, no hurry.

Luo Yu took this time to make canned vegetables. The price of canned vegetables has never declined in the past few days. As I guessed before, vegetables cannot grow overnight, and this high price will continue for a while.

In two hours, 60 canned vegetables were made and they were directly put on the auction house.

Seeing that the time was almost over, Luo Yu took three little cuties to the strike formation.

I just got up to the watchtower and there was a prompt immediately.

【Skasa tribe has arrived at your territory, the attack begins, attack unit: 480 people】

480 people came in one breath in extreme difficulty!

The current rating of the territory is 23,000. In the case of an attack at the end of the month, the ratio is 200:1, which means that 200 points will come with one attack unit. In the case of ordinary attacks, 115 people should come.

But this is extremely difficult, 4 times the average difficulty, and 460 people are converted.

Because the hatred between the Skasa tribe and Luoyu territory is relatively high, the difficulty has increased by 20 again, and the conversion result is 480 people!

This scale is basically equivalent to the intensity of the attack at the end of the month!

Not long after, a large number of attackers appeared in the east corridor connecting the air wall. The leader was the prince who was previously arrested by Luo Yu and sold money to redeem it.

It should be the chief of the tribe now.

Luo Yu observed that more than a hundred people were crowded in the corridor, and more people did not come in.

"Swoosh swish swish!"

This group of people was shocked by the scene in front of them as soon as they appeared. Shouldn’t they appear on a grassland?

What the hell is this?

Fence? Inside the city?

The lord in this place was kicked by a donkey? The city was built on the edge of the territory?

The tribe members had never encountered this situation before, and everyone was confused, but at this time, the six arrow towers opened fire directly!

Six rows of arrows fell rapidly, and eight people were shot to death on the spot!

"What's the situation!"

The people of the tribe who came to attack immediately became panicked and ran away to cover one by one, but there were walls around and bows and arrows were shot from all directions, so they could not escape the attack of the Rain of Arrow!

"Swoosh!"

Another row of arrow rain fell, and after shooting over six people again, the young chief roared: "Shield!"

"Quick! Shield!"

The shield appeared, and the soldiers hid behind the shield one by one, eased some of the arrow rain, but the arrow rain was still falling, and they moved slowly against the shield, and they would be shot randomly.

A large number of tribal people squeezed around the corner at the entrance, and more people had not come in yet, and this was the case that had never happened!
Chapter completed!
