The red general looked at the sky knight who kept falling like a fire meteor in disbelief, and his heart was full of remorse, heartache and questions. Remorse and heartache is that these two thousand Sky Knights, who can be called ace troops, were inexplicably killed by the Blue Fang without playing any role, and he regretted sending all the Sky Knights, such troops are irreplaceable in terms of tactics and combat effectiveness. Now the Sky Knights are all wiped out, and the price paid by the blue side is only tens of thousands of arrows, and the two thousand Sky Knights sent out have not even caused a single casualty to the blue side!

Knowing that one arrow is less than one percent of the size of a hawk dove, it is impossible for a few flaming arrows to ignite an entire huge eagle dove in a few seconds.

Of course, it is impossible for the red general to know Chen Yuan's tactics, and Chen Yuan, who has undergone systematic training and participated in many wars directly or indirectly, knows what is called the rational use of resources. While harvesting resources, Chen Yuan obtained a large amount of neutral gum, because this gum has flammable material properties, so it was used as a strategic resource by Chen Yuan. All the crossbow arrows fired from Zhuge Repeater's crossbow were all impregnated with such gum, and the nine thousand crossbow arrows covered almost most of the eagle doves and knights' bodies without the Sky Knight being able to dodge. This means that after the crossbow attack, all of the Red Sky Knights and mounts are already covered in this extremely flammable gum. The next result was predictable, and these Sky Knights saw that the crossbow arrows were not lethal, so they accelerated and rushed towards the blue camp on the top of the mountain. In fact, even Chen Yuan himself did not expect that with just three rounds of salvos, he would be able to solve all the Sky Knights.

Originally, these knights did not accelerate and dive, but raised the height, under Chen Yuan's calculations, three rounds of salvo shots could only cause a maximum of sixty percent of casualties, of course, Chen Yuan also had a back hand, but the choice of these sky knights directly led to Chen Yuan's remarkable results this time, and even the preparation of the back hand was omitted.

The death of the two thousand Sky Knights directly led to a sharp turn for the worse on the Red side. The Red General must swallow the bitter fruit of losing two thousand Sky Knights. First of all, without the Sky Knights, the Red Side has no air supremacy, and the current Red Fang is simply unable to sanction the two hundred Sky Knights owned by Chen Yuan. Secondly, without the Sky Knight as a sentinel, the current red side is like a blind man, unable to correctly grasp the movements of the blue side in the first place, which directly makes the battle situation passive.

At the foot of the mountain, Red will frown. The current situation is not good for the red side, especially without the presence of the sentinel, the blue side cannot grasp the movement, which is obviously not a good sign. But the red general is still calm, he firmly guards the foot of the mountain, with the advantage of the strength of the blue side can not fight with him, so as long as the two sides continue to spend like this, as soon as the time of three days comes, Chen Yuan will lose, the red general did not think that Chen Yuan will use the sky knight to attack the city, but he subconsciously thinks that Chen Yuan only has two hundred sky knights, and can not cause much damage to his side, after all, in the perception of the red general, the reason why the sky knights are the only ace troops, is because they can ignore the terrain to fight, and the individual combat ability is extremely strong。

But the red general forgot that Chen Yuan has never been a general who plays cards according to routines. At this time, Chen Yuan had already led his two hundred sky knights to fly out from the other side of the mountain, first bypassing the red army at the foot of the mountain to the east, passing through the lake to the south, and finally flying west over the swamp, making a circle, using the current air superiority to avoid the sight of the red army, and directly inserted the red city from the swamp direction.

When he came to the sky above the red city, Chen Yuan didn't talk nonsense, and directly ordered all the sky knights to attack. Ordinary Sky Knights use the dive power of the Eagle Dove in the air, with the four-meter-long Sky Gun in their hands to achieve a breakthrough attack momentum, the impact of the high-altitude dive, coupled with the sharp tip of the gun, this is the invincible attack method of the Sky Knight.

But this time, the two hundred sky knights led by Chen Yuan did not dive and attack like ordinary sky knights. Instead, they were constantly raising the height of their own position, one hundred meters, one hundred and ten meters, one hundred and twenty meters, and soon the two hundred sky knights had already come to a height of one hundred and fifty meters, and the guards in the red city looked up, and they could only see some black spots that were not too big. At this time, the red city has been under martial law, and there are 2,000 strong attackers among the 5,000 infantry reserved by the red general, and they have also stood on the city wall at this time, aiming at Chen Yuan and the two hundred sky knights, and they have also launched an attack, but to the disappointment of the red soldiers, the arrow has lost its strength and fell downward, unable to cause damage to Chen Yuan and the blue knight at all.

Chen Yuan saw that the time was almost up, and stood on the back of an eagle dove and ordered: "Start attacking!" I saw two hundred sky knights pull out a short spear from the backpack on their backs. This short spear was exchanged by Chen Yuan to the blacksmith shop in the city through resources, the tip of the short spear is huge, the whole is streamlined, it is made of pure iron, and there are four hideous blood grooves on the spearhead.

This short spear was designed by Chen Yuan, and it would take a full hundred resources to exchange for one such short spear, so you can imagine its lethality. Chen Yuan equipped each of the two hundred Sky Knights with eight short spears, which meant that these weapons alone cost Chen Yuan 160,000 resources. And the resources collected by Chen Yuan in the past two days are just over 220,000, that is to say, these weapons consume most of Chen Yuan's resources. In order to cooperate with the new tactics of the Sky Knight, Chen Yuan can be said to have made a bloody investment.

As for the power, the RED soldiers in the city below will soon experience it. Receiving the order to attack, the two hundred knights threw their short spears into the city below with all their might. The weight of the short spears themselves, combined with the strength of the knights, combined with the gravitational acceleration at a height of one hundred and fifty meters, caused the two hundred short spears to emit a piercing sonic boom during flight like small **. After that, two hundred short spears landed, and a huge roar resounded throughout the Red Square City. Although the short spear was made of pure iron, the huge impact force still caused the short spear to explode the moment it hit the ground. Two hundred short spears are like two hundred ** on the earth, blasting a bumpy hole in the center of the red city, and the thousands of infantry who were originally standing in the city were directly killed before they had time to react, and because of the burst of the short spears, countless soldiers were seriously injured by the fragments.

After eight rounds of spear throwing, the 5,000 infantry left in the city by the Red General were almost completely wiped out, and the engineers could not stop the Sky Knights at all. Therefore, Chen Yuan easily stepped into the central city lord's mansion of the red square city and obtained the most important certificate of this battle, the city lord seal.

When Chen Yuan took the Great Seal of the Red Fang City Lord in his hand, his consciousness suddenly blurred, and then his consciousness was kicked out of the Spirit Rhino chessboard and returned to his body. On the Lingxi chessboard, a line of big characters appeared "Calmly, one step and three calculations, imaginative, no traces, no casualties to win the enemy city, impeccable, full score pass"
