The appearance of the vacuum mecha made Qu Ming's eyes light up, such a combination was exactly the result he wanted!

Qu Ming currently has no time to combine the rest of the heroes, and the top priority is to arrive at the siege first, occupy the high ground, and kill the human camp army by surprise!

Since it was a second-level hero who was tentatively combining, now that the goal had been achieved, Qu Ming began to really invest in the real material and combine the third-level vacuum mecha!

Rune Fragment (Thruster Lv2) + (Thruster Lv2) + (Thruster Lv2) Rune Essence (Airflow Lv2) = Vacuum Mecha

The recombined three-level vacuum mecha has greatly improved its speed attributes, and the skill effect has also been significantly enhanced!

[Vacuum Propulsion Lv2] consumes 20 energy to unfold the fan-shaped air field, breaking through the air flow, increasing the self's movement speed by 35%, increasing the movement speed of allied units after the fan-shaped air field by 28%, the duration is 18 seconds, and the cooldown is 26 seconds.

With the improvement of skills, all the effects have been slightly enhanced, the cooldown time of skills has been reduced from the previous 10 seconds to 8 seconds, and the energy required to cast skills has also changed from 30 points to 20 points, which is the most practical place!

After all, the combination of the three rune fragments is a 'thruster' that increases speed, and there is no attribute of increasing energy, so a tube of energy value can only use this skill three or four times, if you want to use it continuously, the blue medicine on Qu Ming's body will finally have a place to use!

At this time, Qu Ming didn't care about the rest of the demon army units, and his primary purpose was to quickly bring the 50 skeleton shooters under his command to the siege, so he immediately released the third-level hero vacuum mecha and let it stand in the first place.

The vacuum mecha is quite large, more than three meters tall, the upper body is a flat triangle, similar to a stealth fighter, similar to the position of the front wings on both sides, respectively, light machine guns are mounted, but in terms of caliber and magazine size, not only is the lethality very low, but the attack speed is not very fast.

Behind the wings on both sides, three thrusters are mounted on each side,

There are two mechanical legs under the body, but it looks like the most precise position on the whole body.

Qu Ming was anxious to see the effect of the vacuum mecha's skills, and after making all the preparations, he immediately issued instructions to use the skills.

With the use of the skill 'vacuum propulsion', I saw that the vacuum mecha standing at the forefront of Qu Ming and other units began to run with mechanical legs, Qu Ming naturally did not dare to slack off, and immediately ordered all the units under his command to quickly follow and run out, and the other nearly a thousand demon army units, looking at Qu Ming's team, all showed puzzled expressions.

With a "poof" sound, the thrusters on the wings of the third-level hero vacuum mecha spat out bright green flames, and a heat wave swept towards Qu Ming, but it did not cause him the slightest damage, at this time, the speed of the vacuum mecha had climbed, and as soon as it reached the fan-shaped aura that was almost visible to the naked eye, it took itself as the source, extended to both sides, and finally spread out a distorted space nearly twenty meters long, and Qu Ming and a group of skeleton shooters in this real air field, they suddenly felt that all resistance was eliminated, and there was no sense of weightlessness in space, But I also feel that my body is as light as a wild goose, and my running speed has improved a lot on the original basis!

Qu Ming and a group of skeleton shooters, in the vacuum distortion space behind them created by the vacuum mecha, seemed to be walking with the help of the wind, and sure enough, like the skill amplification effect, the speed increased by about 30%!

Soon, Qu Ming led a team of skeleton shooters far beyond the rest of the demon army units, and a 'vacuum propulsion' skill lasted for 18 seconds, but through this time, the group of demon army units behind him were thrown away!

After the duration of the first skill has passed, it has fallen into a cooldown of 8 seconds, Rao is so, Qu Ming and other units have not stopped hurrying, when the cooldown of the 'vacuum propulsion' skill has passed, it will be turned on again immediately, and the rush speed will soar again!

Although the number of blue bottles on Qu Ming's body is not much, it is enough to cope with the skill consumption of the vacuum mecha, and when he led a group of demon army squads to feel the siege, it is conceivable that the nearly 1,000 units of the demon army that were thrown down at this time were only two-thirds of the way.

At this time, Qu Ming finally showed a sense of relief, standing on the towering siege wall, looking from a distance, the army of the Northern Underworld City only showed a line of heaven at this time, and it was estimated that it would take at least three minutes to advance to the foot of the siege.

Because Qu Ming took the lead in occupying the defenseless siege, he had the authority to control the opening and closing of the besieged city gate, and there is no doubt that the city gate at the foot of the besieged city was naturally closed by Qu Ming at this time.

Although this city gate has been breached by the demon army before, but after a long time, the blood bar of the city gate has returned to full value again, and if you want to break it, even if there are heavy engineering equipment, it will take some time, and these times are the best opportunities for Qu Ming to accumulate military merits!

In the remaining two or three minutes, Qu Ming was not idle, he began to try to combine heroes with any aura ability, which would be the best way to increase the 50 skeleton shooters, and it was also the most direct and powerful way to improve the combat power of Qu Ming's side!

Qu Ming first wanted to take the 'orc' race, thinking that the orcs should be relatively easy to combine, and among the various attributes of the orcs, agility was chosen as the main attribute, and control was secondary.

The most direct effect of this 'domination' attribute is to increase the ability of summoned creatures, such as shamans and animal trainers who can summon beasts, and this attribute is reflected in the word 'group' from the side.

As for the rune essence, Qu Ming chose the 'totem'.

As we all know, the orc race is divided into multiple tribes, and each tribe is inseparable from the 'totem', the rune fragments and essences have been determined, so the rest can only be combined!

Qu Ming first combined a third-level hero composed of all Lv1 through agility + agility + mastery + rune essence 'totem', and the reason why he didn't test the waters with a second-level hero first was because Qu Ming was worried that if there was one less 'agility', the combined hero would change.

Therefore, he is willing to waste one more rune fragment, and also asks for a safe!

After all, if you try to combine all the rune fragments and essences of Lv1, if you are not satisfied with decomposing them, you can bear the loss, but if the rune fragments and essences of Lv2 or Lv3 combine the heroes, and then decompose them, that level of loss, even if it is Qu Ming, you will never be able to bear it!

One Lv2 rune fragment is equivalent to two Lv1 rune fragments, while one Lv3 rune fragment is equivalent to 4 Lv1 rune fragments!

This attempt to combine heroes was very successful, and this time alone made Qu Ming determined to invest in precious rune fragments and essences next!

Next, Qu Ming began to assemble the ideal orcs.
