"The Custom Tower Shop, it's just the right time!"

Li Hanqiang was excited, and immediately used the construction drawings in his hand to build the [Custom Defense Tower Shop] next to the [Defense Tower Shop], this [Custom Defense Tower Shop] is exactly the same as the [Defense Tower Shop], and it also has durability, but there is a plaque in front of this shop, and the plaque reads "Lingxiao City Defense Tower Store".

A group of demons gathered over, shouting, flipping, and stacking Arhats in front of the [Soaring City Defense Tower Shop], and the official Badas also came to watch curiously in the [Multi-functional Turtle Warship].

Li Hanqiang smiled slightly, strode into the store, and a trading window immediately popped up in front of him. Of course, there is not a single product for sale in this window, but there is the attribute information of the [Soaring City Defense Tower Store], which has a description: "If the consumption amount is more than 100,000 gold coupons, the Soaring City Defense Tower Shop will be automatically upgraded, and a maximum of six product columns are allowed!" ”

Soon, a system prompt sounded in Li Hanqiang's ears: "Ding, respected Lingxiao City Lord, the current defense tower store has a commodity column, you can specify a product by yourself, or you can be randomly selected by the system!" ”

"Ding, the system prompts, you can only specify the construction blueprint of the first-level defense tower currently owned by Lingxiao City as a commodity, or there are defense tower construction blueprints randomly selected by the system as a commodity."

"Ding, the system prompts that the price of the defense tower is uniform, the price of the first-level defense tower is 100 gold coupons, the price of the second-level defense tower is 300 gold coupons, the price of the third-level defense tower is 800 gold coupons, the price of the fourth-level defense tower is 2000 gold coupons, the price of the fifth-level defense tower is 6000 gold coupons, the price of the sixth-level defense tower is 18000 gold coupons, and the price of the seventh-level defense tower is 54000 gold coupons......"

After listening to these system prompts, Li Hanqiang shook his head again and again, and sighed: "The architectural drawings of the high-level defense tower are too expensive, the price of the seventh-level is 54,000 golden coupons, and the eighth-level one must not exceed 160,000...... Can't afford it, can't afford it! ”

After a little pondering, Li Hanqiang chose to designate himself, he designated the [Construction Drawings of the Sword Tower] as the first commodity, and with the pleasant sound of the system prompt, the commodity icon immediately appeared in the transaction window in front of Li Hanqiang.

Sure enough, the [Sword Tower's Construction Blueprint] costs 100 gold coupons, which is the same as the [Basic Arrow Tower].

The reason why Li Hanqiang chose [Sword Tower Construction Blueprint] as the first item is naturally a good deal, after all, with his [Tower Transformation] talent, if he is lucky enough, four [Sword Towers] can be combined into a third-level [Four-Story Sword Tower], which is only 400 gold coupons, but the third-level defense tower construction blueprint in the custom defense tower shop costs 800 gold coupons, which is twice as expensive.

"The more advanced the defense tower construction blueprint, the more expensive it is, it's better to do it yourself, and it's cost-effective to synthesize it slowly, with my appearance, I will definitely not lose, and the high-level sword tower is expected to be synthesized!" Li Hanqiang said silently, but he was not in a hurry to open the second and third commodity columns.

In his opinion, now that there is a [Sword Tower Construction Blueprint], there is nothing else to ask for, wait until he mutates a first-level [Rocket Launch Tower] or [Self-propelled Turret], [Returning Vulgar Tower], etc., and then open the commodity column, and it is not too late to specify the product.

If it's a [Rocket Tower Launch Tower], 100 gold coupons, it's necessary to hoard, but it's a pity that your own [Rocket Tower] has been upgraded to a second-level defense tower and can't be designated as a commodity, and the next time you want to mutate out of a [Rocket Tower], you don't know how long you'll have to wait.

As for letting the system randomly determine the goods, in Li Hanqiang's view, it is very irrational.

Immediately afterwards, Li Hanqiang used the [Random Building Upgrade Scroll] with great anticipation, and a crisp system prompt immediately sounded in his ears: "Ding, respected City Lord of Lingxiao City, if you use the upgrade scroll, a building in Lingxiao City will be upgraded...... Congratulations, the Grenade Workshop has been upgraded! ”

"The Grenade Workshop? That's fine, too! Li Hanqiang frowned, and hurriedly called up the attribute panel of the West Factory.

[Fire Grenade Workshop] is an annex to the West Factory, with the West Factory upgraded to the LV5 barracks, this workshop already has five production lines, which can transform the goblin vendor's cart into a grenade chariot, and can also make [Fire Grenades], but so far, the biggest role of this [Fire Grenade Workshop] is probably to make snacks for Erhei.

Li Hanqiang originally had great hopes for this [Fire Grenade Workshop], after all, the Fire Grenade Chariot could allow the Demon Mountain Demon to have the ability to siege the city, but later he found that the Fire Grenade Chariot with a range of only 300 meters was not as powerful as he imagined, even if Erhei could transform into a [Beetle Transport Truck] and provide a large amount of grenade support, it was still not powerful, and it was also limited by the number of Demon Mountain Demons.

Now that he wants to attack the city, Li Hanqiang doesn't need to send a grenade chariot at all, just send troops to bulldoze it, which is much more refreshing, and he is about to forget that the demon mountain demon can push the grenade chariot to attack the city.

"I want to see how this grenade workshop is upgraded after it is upgraded, and I hope to have a superb ability!"

Li Hanqiang quickly checked it out and found that the upgraded [Fire Grenade Workshop] only had one more ability to make [Siege Grenades], and each production line could make a hundred per day.

[Siege grenade: The fire grenade workshop can make siege grenades, siege grenades have powerful siege capabilities, and can be used as consumable hidden weapons (thieves and assassin classes can be equipped), and they explode after fifteen seconds of throwing, which can cause a powerful area bombing effect, and powerful collisions, flames, etc. can also ignite siege grenades and make them explode directly! ] 】

"Grenades! This secret weapon is interesting.,The demon mountain demon can be equipped.,I just don't know how powerful it is.,I'm going to find a chance to give it a try! ”

Li Hanqiang said silently, and he was satisfied with the upgrade of the [Fire Grenade Workshop].

Walking out of the [Soaring City Defense Tower Shop], Li Hanqiang used the [Random Defense Tower Upgrade Scroll] again, this scroll is not as good as the [Random Building Upgrade Scroll], it can only raise the defense tower by one level, and the highest defense tower can only be upgraded to level five, so it is only effective for defense towers below level five, and there is a one-third chance of upgrade failure.

"Ding, Honorable Lord of Soaring City, you used a random tower upgrade scroll, and one of the towers in Soaring City will be upgraded...... Congratulations, the Level 2 Defense Tower Rocket Launch Tower has been upgraded to a Level 3 Defense Tower, and its capabilities have been greatly enhanced! ”

"The rocket tower has been upgraded!" Li Han was overjoyed, and hurriedly checked the attribute information of the [Rocket Launch Tower], and found that in addition to the basic siege damage increased to 33,000 points, this level of [Rocket Launch Tower] also has a new ability: [Manned Rocket]!

Manned Rocket: Rocket towers can be loaded with one player or one troop unit. Note: Players or units must not be taller than five meters tall and can safely land on the bombing site after a rocket bombardment! 】

"This ability ......" Li Hanqiang frowned slightly after reading the description of this [manned rocket] ability, and immediately smiled.

A brilliant idea popped into his head, but he looked back at the [Custom Tower Shop] with blazing eyes.

"If the blueprints for the construction of this three-stage rocket tower can be purchased infinitely, then I will be invincible!" Li Hanqiang slapped his palms, he decided to take a gamble, turned around and entered the [Lingxiao City Defense Tower Store] again, directly consumed five thousand points of chaotic energy to open two commodity columns, and then chose to randomly determine the goods by the system.
