Just got more than 10,000 gold coins, and only 5,000 were used to upgrade the Heart of Chaos, Li Hanqiang now has a lot of spare money, and there is no shortage of chaotic energy, so his mentality is completely released, and he decided to synthesize the nine [Open Spear and Dark Arrow Towers] first.

He first tried the synthesis of the twin towers, but he actually got off to a bad start and failed as soon as he came up.

"It's okay, keep coming!"

Li Hanqiang is now very arrogant, and he didn't care about the loss of a second-level [Bright Spear and Dark Arrow Tower], and the second synthesis was successful, and he created a third-level [Bright Spear and Dark Arrow Tower].

The attack distance of the three-level [Bright Gun Dark Arrow Tower] has been increased to 300 meters, the attack speed is 1 time per second, it occupies four Chaos Stone Tablets, the attack characteristics remain the same, and it still has a mortal effect, the damage value of the open gun attack has been increased to 400 points, and the damage value of the dark arrow attack has been increased to 200, and when the special effect of death-bound is triggered, the elite monster will lose 8000 HP, and the boss monster will lose 4000 HP.

Li Hanqiang pondered for a while, and felt that when facing a large number of ordinary enemies, the effect of this third-level [Bright Spear and Dark Arrow Tower] was definitely not as good as that of two second-level [Bright Spear and Dark Arrow Towers], after all, the attack speed was the same, and the two second-level towers could have double the special effect of death.

Of course, if it is an attack on a high-level elite monster or a boss, the third-level [Open Spear and Dark Arrow Tower] with a range of 300 meters will definitely be more powerful.

"The mortal effect is a god effect, it seems that I need to get another [Speed Changing Tower] and play with the defense tower synthesis!"

Li Hanqiang thought silently, and then chose to combine the third-level [Bright Spear and Dark Arrow Tower] and the 4 second-level [Bright Spear and Dark Arrow Tower].

According to the law he mastered, it seems that two defense towers of the same level can be synthesized into a higher-level defense tower, and choosing multiple defense towers to synthesize can reduce the probability of losing high-level defense towers after the synthesis fails, but this synthesis requires more chaotic energy, after all, the combined towers are based on the number of defense towers to deduct chaotic energy.

Li Hanqiang is not bad for chaotic energy now, his mind moved, and he consumed fifty points of chaotic energy, but the synthesis failed, and he damaged a second-level [Open Spear and Dark Arrow Tower], he can bear it for the time being, and continue to synthesize according to this method.

Finally, a beautiful voice came: "Ding, the synthesis is successful, congratulations on obtaining the level 4 mutant defense tower [Light and Dark Tower]!" ”

Suddenly, the four second-level [Bright Spear and Dark Arrow Towers] disappeared, and the original third-level [Bright Spear and Dark Arrow Towers] quickly rose to become a forty-meter-high giant tower, like a temple below, and like an arrow tower above, alternating light and darkness on it, which looked a little weird.

Facing this fourth-level [Light and Dark Tower], Li Hanqiang looked at it for a long time.

Although the [Light and Dark Tower] is tall, its appearance is far less domineering than the [Four-Story Sword Tower] and the [Flame Demon Sword], and its attributes have also changed.

"The specific power of this light and dark tower has to be tested in actual combat to be seen, so it shouldn't be bad. If there are too many of them, it should be very powerful to summon a large number of broadswordsmen, pikemen, and shadow towers in the war corridor. ”

Li Hanqiang pondered silently, the cost of this fourth-level [Open Spear and Dark Arrow Tower] was not low, and he felt that its power should not be lower than that of an ordinary fourth-level defense tower.

Next, Li Hanqiang bought 30 [Basic Arrow Tower Construction Blueprints] and 10 [Basic Retardation Tower Construction Blueprints] in one go, and played [Tower Change] wildly.

He is now completely pursuing high-level towers, and all low-level towers are synthetic, and the garbage towers such as [Rear Turret] and [Rocket Turret] are completely used as synthetic materials.

Level 4 [Light and Dark Tower] × 2;

Level 3 [Four-Story Sword Tower] ×4;

Level 3 [Flame Demon Sword] ×1;

Level 2 [Double Ringing Head Cannon] ×1

Level 2 [Bright Gun and Dark Arrow Tower] ×1;

Level 2 [Speed Shift Returning Tower] ×2;

Level 2 [Flame Tower] ×1;

Level 2 [Beastcatcher] ×1;

Level 1 [Basic Retardation Tower] ×1;

Level 1 [Self-propelled Turret] ×1;

1st level [anti-aircraft turret] ×1;

There are a total of 14, accounting for 35 Chaos Slates, counting the eight pieces occupied by the Ganoderma lucidum tree, there are still 6 Chaos Slabs left in Li Hanqiang's house.

Li Hanqiang's imaginary [Speed Changing Spear Dark Arrow Tower] was not synthesized, but he used the [Horse Rear Turret], [Rocket Turret], [Sword Tower], and [Speed Changing Tower] to accidentally synthesize a third-level [Costume Change Tower].

This [Costume Change Tower] can randomly switch between the three attack forms of turret, arrow tower, and sword qi tower, which is equivalent to the attack power data of the four defense towers of [Horse Rear Turret], [Rocket Turret], [Sword Tower], and [Speed Shift Tower], Li Hanqiang felt that this defense tower was a garbage tower, and activated the [Tower Transformation] talent to mutate it several times in a row, but he was not satisfied, and finally the mutation failed and was demolished, wasting a lot of chaotic energy in vain.

Now those defense towers that are kept by Li Hanqiang are all considered good by Li Hanqiang, and he is not willing to take the risk of mutation.

"Even with the blessing of luck, the tower transformation is also risky, and with my current financial resources, it is not enough to study the formula of the tower."

Li Hanqiang shook his head, the formula for the combined tower he had mastered now was undoubtedly the most valuable for the [Flame Demon Sword] and the [Changing Speed Returning Tower], as for the [Four-Story Sword Tower] and the [Light and Dark Tower], the formula was too simple, as long as there were gold coins and chaotic energy, it could be synthesized in batches.

Li Hanqiang did not continue to change the tower, but spent Chaos Energy to adjust the position of the defense tower.

The placement of the defense tower is still very particular, Li Hanqiang put the [Flame Demon Sword] and [Four-story Sword Tower] in the front before, but the [Speed Change Tower] and [Bright Gun Dark Arrow Tower] are placed in the rear, and the firepower center is actually in front of the [Flame Demon Sword] and [Four-story Sword Tower], it is a little stupid to encounter the King of the Void, and the [Speed Change Slow Tower] and [Bright Gun Dark Arrow Tower] in the rear cannot be attacked at all.

He reflected for a while, the [Anti-aircraft Turret] with a range of 1,000 meters was still left in the rear, the position of the [Flame Demon Sword] and [Four-Story Sword Tower] with a range of 300 meters remained unchanged, the two [Light and Dark Towers] with a range of 400 meters were placed 100 meters behind them, and the rest of the second-level towers and first-level towers were all placed in front according to the range, concentrating the center of fire of the defense tower at the very edge of the range of the [Flame Demon Sword].

In this way, if he encounters the King of the Void again, once he approaches the range of the [Flame Demon Sword], he will be attacked by a large number of defense towers, and the basic attack power of these defense towers, plus the mortal effects of [First Shot], [Dual Sword Combination], [Four Swords Combination], [Returning the Vulgar] and [Open Gun and Dark Arrow], it is estimated that 500,000 HP may not last a minute.
