Seeing that the first detachment had not heard from him for a long time, Zuo Lang sent the second detachment to support. The second detachment is different from the first detachment, they become archers after landing, that is, they can attack the Five Elements Arrow Tower on the Fengshen Ridge......

Syllable!

The Five Elements Arrow Tower was attacked, and it lost 10 durability points, although it has 1000 durability, but the second detachment has more than one archer, and if it continues like this, it will be destroyed soon, what should I do?

"Kunlun Mirror, how to improve the durability of the Five Elements Arrow Tower?" Xu Kai asked.

"You haven't claimed the first wave of rewards yet."

"Oh? And the rewards? Xu Kai found that a prompt to receive the award appeared in the lower right corner, and quickly clicked on it. Although these things appeared in front of Xu Kai, they were not much different from the game interface, and his hand was a mouse, which was very convenient, and it also made Xu Kai feel more cordial, saying that this was immersive and could not express his mood at this time.

In the pack, 100,000 Kunlun Coins, 100 Kunlun Jade, and 50 Enhancement Stones appeared.

"Kunlun jade?" Xu Kai looked carefully and explained, this Kunlun jade is exactly what improves the durability of the Five Elements Arrow Tower, 1 can increase the durability by 10 points, although it has a little effect, but the durability will always continue to decline, and he was a little disappointed.

At this time, the other Five Elements Arrow Towers were also attacked, and it was not a way for the two sides to shoot at each other like this, because it was not known how many waves of attacks would follow.

Xu Kai sighed: "Alas, it would be nice if the arrow tower could be repaired......"

"Of course you can repair it, but you have to hire maintenance workers."

"Hire again?" Xu Kai has already hired a lot of people to work in the Kunlun Secret Realm, and his salary is still calculated on an hourly basis, if he hadn't kept a copy every day, the Kunlun coins would have been insufficient.

"I can't bear the Kunlun coin, you can do it yourself."

"That's it!" Xu Kai made a careful calculation and decided to hire only 5 maintenance workers, and then built 10 Five Elements Arrow Towers, each worker was responsible for repairing 3 arrow towers, and there was still plenty of time.

The defensive measures have been completed, and the rest is to attack, Xu Kai used all 50 strengthening stones on the fire attribute of the Five Elements Arrow Tower, because the archers of the second detachment are all metallic, fire and gold, there is no reason not to upgrade it!

The soldier who was hit by the rocket entered a state of continuous burning, plus his own five elements of gold, which doubled the damage, and after a while, the kung fu health was drained, and the speed of eliminating the second detachment was several times faster than that of the first detachment, because there were more arrow towers and the attack was also higher, Xu Kai very easily harvested 100,000 Kunlun coins, 100 Kunlun jade and 50 strengthening stones again, although the reward was the same as before, it was enough to raise the strength of the arrow tower to a new level.

The next third, fourth, and fifth waves of soldiers all have different Five Element attributes, all of which are restrained by the Five Elements Arrow Tower, and the faster they kill, the faster they kill, which makes Zuo Lang very puzzled, because these soldiers are all elite troops, how could they send five without hearing from them?

There were five troops behind him, and he thought to himself: It seems that there are too few soldiers in each dispatch, so why don't we go together......

As a result, the five troops fell to the Kunlun Secret Realm at the same time, and then they were swept into the Five Elements Array of the Gods, and continued to be attacked by the Five Elements Arrow Tower. Now Xu Kai's Five Elements Arrow Tower not only has a very high attack, but also has a much faster attack speed, although Zuo Lang has brought many people, it is always not much different from the previous one, and the losses are even more heavy.

This time Zuo Lang still didn't go out with the army, he was an official, he only needed to command on it, he didn't need to go out in person, he didn't want to risk his life, it seems that there is not much difference between immortals and mortals, Xu Kai saw it in his eyes, and he couldn't wait to kill him in seconds with an arrow, but Zuo Lang's combat power was as high as 1000000, and he couldn't hurt him at all, if he exposed himself, he was afraid of his life.

The ten troops were all wiped out in this way, and Zuo Lang didn't dare to come down, because if he fell to the ground, he would become a mortal, and mortals would die, even if his combat effectiveness was super high, he didn't want to be so careless. Moreover, legend has it that there is a mysterious master in the Kunlun Secret Realm, this person has the same power as a god, if he becomes a mortal, how can he be his opponent?

Zuo Lang hesitated again and again, and finally decided to retreat, the first crisis of the Kunlun Secret Realm was finally lifted, Xu Kai gained a lot, and saved 300,000 Kunlun coins in case of emergency, which is much easier than the next copy, because they are all Five Elements Arrow Tower and maintenance workers are working, he is happy to be idle on the side, because in the last few waves, even the commander of the enemy army can not resist the attack of the Five Elements Arrow Tower, and there is no need for Xu Kai to take action personally, saving a lot of effort.
