Kong Xiuying and Chen Xiangxiang immediately quickly made new adjustments to the formation of the NPC soldiers, the new formation layout is like this, the swordsmen are arranged in three rows in three, four, and three formations, the first row has three swordsmen, and the second row has four swordsmen, the distance between the first row and the second row is 1 meter, and the swordsmen in the first and second rows are misplaced with each other; In other words, the first row of swordsmen and the second row of swordsmen are not only staggered by one meter in the longitudinal direction, but also 0.75 meters in the transverse direction, while the soldiers in the same row maintain a distance of 1.5 meters from each other.

Chen Xiangxiang and the remaining three sword soldiers formed the third row, the third row and the second row were vertically aligned, and the third row and the second row were separated by another 1.5 meters.

Chen Xiangxiang gave priority to the swordsmen with high blood value in the first and second rows.

Kong Xiuying arranged the archers into a formation of 3, 4, and 3, and discharged the fourth, fifth, and sixth rows of NPC soldiers; The fourth and fifth rows are vertically aligned with Chen Xiangxiang's second and third rows of knife soldiers.

Kong Xiuying was lined up in the fourth row with 3 archers, and the remaining 3 archers formed the sixth row, which was vertically aligned with Chen Xiangxiang's first row of sword soldiers.

The distance between the soldiers in the fourth and fifth rows and their front rows is 1.5 meters, and the distance between the sixth and fifth rows is 1 meter.

The sword soldier and the archer are uniform, and they are handed over to the 'sword soldier No. 1' for verbal command, and the first order given by the 'sword soldier No. 1' to the NPC soldier is very simple and straightforward: "The duty of the archer is to guard the soldiers in the first and second rows; When I say 'right', the 'archers' attack the bats on the 'right' side of the swordmen, and the swordsmen attack the bats on the 'left', and when I say 'sides', the archers can attack the 'sides' at will, and the swordsmen attack the bats in front. ”

In the course of the battle, the 'Sword Soldier No. 1' will also adjust the attack direction of a certain archer according to the actual battle situation, so as not to neglect the protection of a certain sword soldier; Equipped with a holographic recorder, 'Knife Soldier 1 can fully observe the battle situation in the entire mental force field space, no matter where it is.

After adjusting the formation here, and advancing seven or eight meters further, it encountered the third wave of attacks from the bats.

In this wave of attacking bats, there are larger bats with a wingspan of 80 cm wide, which are also 1:5 in number ratio to bats with a wingspan of 60 cm, and can generate up to 7 HP loss when effectively attacking NPC soldiers.

This third wave of bat attacks lasted for 1 minute, and the number of bats in the bat swarm reached tens of thousands, and the first row of knife soldiers lost an average of 50 points, the second row of knife soldiers lost 40 points, and the third row of knife soldiers lost much better, with an average loss of 10 points.

The average amount of health dropped by an archer is 10 points.

By the end of the third wave of bats' attacks, the lowest HP in the sword soldier will have a remaining HP value of 60, and the highest HP value in the knife soldier will reach 100; The average remaining health value of an archer is 70.

Although the number of bats attacking in this wave was larger, and larger bats were added to it, due to the multiple defense lines of the NPC soldiers, the soldiers at the back of the defense line suffered less damage, and the defense range of the 10 archers was reduced, which also made their defense against the defensive surface stronger.

Again, this time under the command of 'Knife Soldier No. 1', the cooperation of the two arms has also achieved certain results, the archers under the command of 'Knife Soldier No. 1', at any time adjust their attack area to cooperate with the defense of the knife soldiers, while producing lethality to bats, but also play a good role in protecting the knife soldiers in the front; every time the archers release arrows, the attacking knife soldiers are negligent in guarding against the bats in the area.

The rate of fire of archers is one arrow per second, but fortunately, in the game, archers can shoot arrows willfully, and the arrows in the archers' quiver are always full, so there is no need to worry about the arrows being shot out.

In this wave of bat swarms, more than 500 bats were exterminated.

Kong Xiuying in this wave of bat swarm attacks, her use of the 'four birds with one stone' skill success rate has reached forty percent, when she uses the 'four birds with one stone' skill, is to give priority to the large bats to deal with the next bat, if you can't find a big bat for a while, she will retreat to the second, will not delay the frequency of her mental power commands.

In this wave of bat swarm's attacks, Chen Xiangxiang's success rate in using the 'Killing Four Birds with One Stone' skill can reach 20%.

Kong Xiuying and Chen Xiangxiang were still not injured in this wave of bat swarm attacks, which is also related to the fact that they did not bear the brunt of the bat swarm attacks.

Before continuing to move forward, Chen Xiangxiang only made a partial adjustment to the arrangement of the knife soldiers, that is, the positions of the first row and the third row of sword soldiers were swapped just now, so that the sword soldiers with high blood volume and stock were in the forefront position.

When the formation was regrouped and another seven or eight meters forward, the fourth wave of the batswarm arrived.

In this wave of bats, a new bright new breed of bats has been added, this bat is different from the general bat is gray-black, but a silver bat, this silver bat, the wingspan has reached 1 meter, compared with the kind of wingspan 80 centimeters of large bats, the number is less, and the ratio between the two sides is also 1:5.

This silver bat can effectively attack NPC Soldiers, causing them to lose up to 12 HP.

It's a pity that this kind of silver bats have no chance to show their strong lethality in the attack, because they are too few after all, only 8 of them appeared in this wave of attacks, and whenever they appear in the mental force field space, they will be focused on by Kong Xiuying and Chen Xiangxiang, and it is impossible to give them a chance to attack NPC soldiers, although the success rate of the two of them when using the 'killing four birds with one stone' skill is not high, but they will at least ensure that the spiritual power command of the silver bat cannot be missed.

Since Kong Xiuying and Chen Xiangxiang are currently focusing on practicing the skill of 'killing four birds with one stone', the two sides also have a division of labor in the defensive division of the spatial area of the spiritual force field, neither can they waste their ability because the two of them use the spiritual force command to command the same bat at the same time, nor will they cause the scope of the three regardless because the division of the area is not detailed;

This fourth wave of bat attacks also lasted for 1 minute, and the number of bats in the bat swarm was about the same as the previous wave, that is, more than 10,000 points, and the average blood loss of the first row of knife soldiers was 45 points, the blood loss of the second row of knife soldiers was 35 points, and the blood loss of the third row of knife soldiers was about 10 points.

The average amount of health dropped by archers in this wave is still 10 points.

Compared with the previous wave of fighting with the sword soldiers, the archers in this wave of dealing with the attack of bats, and the cooperation with the sword soldiers seems to be much more tacit.

In this wave of bat swarms, more than 700 bats were killed.

In this wave of bat swarm attacks, Kong Xiuying's success rate of using the 'Four Birds with One Stone' skill has reached 50 percent, and Chen Xiangxiang's success rate of using the 'Four Birds with One Stone' skill has reached 40 percent.

When the two of them used the 'Killing Four Birds with One Stone' skill, they gave priority to choosing a large bat to issue mental power commands.

Kong Xiuying and Chen Xiangxiang were still unharmed in this wave of bat swarm attacks.

After this round of fighting, the four swordsmen in the second row lost the most HP, and after four rounds, they lost an average of 115 HP points, and the average remaining HP value was 35 points.

The rest of the swordsmen have a health value between 55 and 50, and the average remaining health of the archers is 60.

Moving forward, I don't know if the swordsmen can withstand the next wave of attacks from the bats with their current HP value; From the analysis of the situation of high-level bats appearing one by one, there may be golden bats in the next wave, but as long as the number is scarce, Kong Xiuying and Chen Xiangxiang don't care about it, after all, the kind of rare bats that are too big are also convenient for them to use their mental power to command them to attack other bats.

As for the amount of HP lost by NPC soldiers, they also come with a health recovery pill, which allows all NPC soldiers to get a chance to regain full health.

However, Kong Xiuying now has a new idea, she feels that if they are at such a rate of blood loss, even if they can make the NPC soldiers full of blood in the next wave of battles, they will not be able to resist a few waves of bat swarm attacks, regardless of whether they can get the treasures in the bat cave, it would be a pity to say that such a good opportunity to exercise mental strength will end in a few moments; Kong Xiuying felt that it was necessary to immediately change the current operational thinking.
