Not long after, the 47th wave of monster siege ended, and Li Hanqiang went to receive the reward for defending the city.

"Ding, congratulations on successfully receiving the siege reward of the 47th wave of monster sieges, you have obtained the [Stonehenge Air Defense Technology Scroll], the item is rated as rare, congratulations to the player!"

"Tech scrolls?" Li Hanqiang already had an extra golden scroll in his hand at this moment, and he hurriedly opened it to check it.

Stonehenge: Air Defense Technology Scroll: Special item, technology scroll, exclusive to Chaos City Lord, after use, turn on Stonehenge Air Defense Technology, you can build a Stonehenge Air Defense System to protect an area.

Introduction to the Stonehenge air defense system: A complete set of Stonehenge air defense system consists of eight hybrid guns with a caliber of 1200 mm to form a disc-shaped air defense array, with an air defense radius of 5,000 meters, which can effectively intercept high-altitude strikes and destroy hostile flying units such as void airships and war machinery.

The Stonehenge air defense system can be stacked, and multiple sets of Stonehenge air defense systems can be superimposed to strengthen the air defense capability.

Hybrid gun introduction: hybrid gun has a strong attack power and accurate self-tracking lock strike ability, while equipped with lifting device, radar device, anti-stealth device, anti-jamming device, automatic repair device, the gun body is huge, a set of eight hybrid guns can constitute a 360-degree high-altitude defense network without dead angles, hybrid guns can replenish their own energy, usually camouflaged with boulders, detect high-altitude strikes when revealing the gun body, and carry out autonomous attacks.

Note that the hybrid cannon cannot attack ground units.

Hybrid Cannon crafting materials: Chaos Gem ×1, Iron Ore ×999, Silver Ore × 999, Copper Ore ×999, Crystal Ore ×999......

Note: The Stonehenge air defense system can be built in any location, including sub-bases, temporary garrison areas, etc., and the hybrid gun can also be dismantled and carried, and transferred to the layout.

"This Stonehenge air defense system seems to be pretty good, if it is arranged, there is no need to be afraid of others using long-range attacks such as rocket launch towers to raid!"

Li Hanqiang suddenly had a lot of ideas in his heart, and he felt that the Stonehenge air defense system should not only be arranged in Lingxiao City, but also in the Demon Mountain Cave Mansion, Bibo Lake, Kunwu Mountain, East Factory, West Factory, Dragon Slaying City, Wolong City and other places.

In this way, if they encounter a situation similar to the attack of the fish monster during the original founding mission, these Void Islands will also have a certain amount of air defense.

The Stonehenge air defense system can also be superimposed, as long as the resources are sufficient, a few more sets will be arranged, and the defensive firepower will naturally be superimposed.

The sub-base also has the need to arrange the Stonehenge air defense system, combined with the Taiyi Xuanguang cannon, to greatly improve the defense capability.

In addition, this Stonehenge air defense system can also be transferred and arranged, and it can be used in the future if you lead troops to fight, camp outside, or grab territory or something.

Li Hanqiang quickly summoned [Chaos City Lord Li Hanqiang], as well as Jack Bodhisattva and Zhenguo Gong Badasi, and asked them to research and manufacture hybrid cannons for the Stonehenge air defense system, and arrange them in Lingxiao City and various Void Islands as soon as possible.

Among the materials for the production of hybrid guns, the Chaos Gem is the most precious, and one cannon will consume one, but fortunately, Li Hanqiang still has the accumulated Chaos Gem in his hand, and it is no problem to make twenty or thirty for the time being.

Li Hanqiang thought about it, and didn't rush to continue to start the 48th wave of monster siege, but just gave Badasi, the prince of Yipin Town, a holiday, to let him rest, while he came to the war corridor and took out the [Construction Blueprint of the Holy Light Tower], [Construction Blueprint of the Tower of Purification], [Construction Blueprint of the Tower of Punishment] and [Silver Knight Statue] obtained from the robbery dungeon.

The first-level [Holy Light Tower] can fire Holy Light Bullets, which have a small area of splash damage effect, and their power is similar to that of Level 1 [Basic Arrow Tower] and [Basic Turret], which can be regarded as an intermediate defense tower with the characteristics of these two basic defense towers.

[Tower of Purification] can stimulate the light of evolution, purify the buff status of hostile targets, and at the same time have a stronger damage effect on summoned units, which is considered a kind of defense tower with "specialty", but the base attack power is a little poor.

[Tower of Punishment] is a single attack defense tower, the attack power is relatively high, it can stimulate the punishment lightning, and there is a small chance to cause the punishment effect when attacking the target, the punishment effect includes reduced movement speed, reduced attack power, weakened defense, and so on.

[Holy Light Tower], [Purification Tower] and [Punishment Tower] can actually only be regarded as ordinary defense towers, except for the sound and light effects of "Holy Light Bullet", "Purifying Light" and "Punishment Lightning", which are more dazzling, they do not have too prominent abilities, and in addition to the fact that they are all low-level towers, Li Hanqiang feels that there is no need to build them at all.

However, you can use them as materials for [Tower Change], and when you accumulate more drawings in the future, you can do single tower mutation or multi-tower synthesis.

However, the [Silver Knight Statue] is a bit extraordinary, this is a rare defense tower that can grow up to level nine!

Li Hanqiang placed this [Silver Knight Statue] on a chaotic stone slab on the edge of the war corridor, saying that it was a "Silver Knight", and after it was formed, it had no horse at all, just a silver statue wearing a silver battle armor, a mask and a helmet, with wings folded behind his back, holding the hilt of a giant sword in both hands, and the giant sword was stabbed in front of him.

Looking at the attribute data alone, Li Hanqiang is willing to call this level [Silver Knight] the weakest defense tower, with an attack power of only 10 points, and it is also a melee attack, the attack speed is so slow, the effect of [Critical Strike] is also a picking, and even the first-level [Cheap Tower] is afraid that the output ability is much stronger than this [Silver Knight].

Especially the melee attack, which is a hard wound.

Fortunately, the Silver Knight is easy to level up, and as long as you kill 100 enemies, you can generate Level 2!

Coupled with the appearance of the silver statue of [Silver Knight], Li Hanqiang is quite looking forward to it.

"Let's upgrade this silver knight first, even if it can't be used, it should be good to use it as a material for the tower!"

Li Hanqiang decided that the next wave of monsters attacking the city would brush up the number of enemies killed for this [Silver Knight].

However, with the strength of today's siege monsters, even if Badas controls the tower with superb skills, it will not be easy to brush the number of enemies killed for this [Silver Knight].

After all, it only has ten attack power, and it is still a melee attack, and it takes three seconds to cut a sword, and if you want to make up the knife and get a human head, it is definitely a technical job.

"Do you want me to find an aunt who hangs up the city lord and uses low-level monsters to brush the level of the silver knight?"

Li Hanqiang had an idea, if it was a low-level mob, the upgrade speed of the silver knight would be much faster, he felt that this method was good, through the ability of the Heaven and Earth Hall, he could use the [Silver Knight] as a dowry or dowry, and easily send it to the Chaos City of the City Lord's aunt, if the level was brushed, he could easily get it back through the Heaven and Earth Hall.

Li Hanqiang was bored anyway, and immediately wanted to try it, so he contacted the head of the aunt, that is, the god thief, and asked him to arrange it.
