When others were reorganizing the army, a large number of Zerg in Li Yao's construction space were produced, and then smelted into steel Zerg.

Li Yao has also experienced continuous battles, and the massive energy units accumulated in the structure space, since Li Yao knew that he was going to go through a big war, he began to go all out when he was in the Arcane Tower.

The Iron Zerg Legion was continuously manufactured, and because Li Yao's strong path chose to merge with the mother worm and the mechanical heart, the two things were upgraded to a higher level, and both the Zerg and the machine were raised by one level again.

Originally, Li Yao felt that his strength at this stage was enough, and there was no need to show better troops, or strengthen the troops again, but this battle was unusual, and it was impossible to prepare too much to capture a main city.

This is promoted under the enhancement of the fit matter, and both things have been upgraded to level four, which is their own level, this is because after making up for the origin of the promotion, the two of them are also a complete strength form, not the kind that is weakened by the player.

This upgrade allows Li Yao to produce more elite and advanced ace troops, and can summon two heroes at the Hero Altar.

The strength of the Heart of Machines allows Li Yao to produce more mechanical troops, but these classes are not decisive, and they are not stronger than the ace bugs, plus the cost is huge, so Li Yao's Heart of Machines is mainly based on strengthening bugs.

However, the mechanical class is also very powerful, but it is not easy to manufacture, and Li Yao is ready to obtain massive resources after occupying the main city.

These days, Li Yao has already sorted out his thoughts, two heroes, one is the king worm of the huge void.

The size of this insect was incomparably huge, and the Withered Sun was only two-thirds the size of him, which showed how huge it was.

The Void Worm is a battleship worm of the Zerg that crosses the starry sky of the universe, because of the limitation of strength, Li Yao only summoned the camp level, but it is enough, and his internal contains the power of the law, and the huge space is not comparable to the air fortress.

After the transformation of the enhanced Mechanical Heart Furnace, it becomes the Iron Void King Worm.

Iron Void King Worm

Grade: Advanced Faction (Alienated)

Life: 90 million

Armor: Biochemical Armor, Body of Steel, Swarm Protection

Specialty: Void Leap, Dimensional Rush, Void Expansion, Indestructible, Void Mystery.

Skills: Void Roar, Biochemical Breath, Dimension Worm Summon, Void Collision.

Li Yao looked at this huge Zerg hero and was very satisfied, the only regret was that Li Yao did not find the information of the Void Worm's nest, otherwise Li Yao would definitely build a strong army of Void Worms.

This hero is simply Li Yao's second air fortress, and he can still carry it with him, but it is much more convenient than that of the Kuyang.

This battle is equivalent to having three flying fortresses to participate in the battle, which is definitely a huge boost.

Biochemical armor is the armor of the Void Worm itself, like a city wall, the body of steel is the effect of smelting, and the swarm protection is related to the summoning of dimensional insects, which is a biological enchantment.

Void Leap is equivalent to teleportation, but it requires a rapid acceleration of the dimension to a certain extent.

Indestructible is the characteristic obtained by its own strength and smelting, and it is immune to most damage.

The Void Expansion is the reason why he can accommodate countless Zerg armies in his body, which is equivalent to the structure space, but it is different.

The Void Mystery allows him to master the power of the Void, be good at concealment, and be immune to some attacks.

In terms of skills, Void Roar is a sonic skill that weakens the opponent, breath does not need to be explained, and sprays strong acid.

Void Rush is a collision skill, using his body size to crush the opponent, and the Dimension Worm Summoning is to summon the Dimension Worm to help him protect himself alive to form his own armor and shield the arrow.

The second hero is the mechanical class, Li Yao chose a big engineer, is a mechanical life, has strong manufacturing capabilities, is a support hero, has no combat effectiveness, but he can make the mechanical heart play the original 200% efficiency, and it is also the secret killer weapon of Li Yao's attack on the main city to build engineering weapons.

The Heart of Machines can be built by many classes, but due to the limitations of materials and time, Li Yao has no choice but to choose the simplest fighter.

At first, Li Yao could only rely on his own resources to produce, Li Yao planned to prepare 10,000 fighters, but with the resources of the main city, Li Yao estimated that by the time he attacked the main city, there would be more than 100,000 fighters who could participate in the battle. Definitely an ace air force.

This is the only mechanical class that has the conditions to make and can see the effect in a short time, and the others are the smelting of the enhanced version of the mechanical heart.

The focus is still on the Zerg side, and after Li Yao's consideration, he still further strengthened the Zerg Legion in his hand.

The steel cockroach has gradually been unable to keep up with Li Yao's footsteps, although the steel cockroach is very strong, but it is still a little weak to resist the ace army.

Therefore, Li Yao advanced the steel cockroach nest into the nest of the destroyer and the thunder beast respectively, and the existing steel cockroach was also constantly evolving into the ace of these two mutant zergs.

Both the Thunder Beast and the Saboteur have gone further in the defense and recovery of the Steel Cockroach, making it more difficult to kill, in addition, the Thunder Beast has more powerful melee combat capabilities, and its combat effectiveness is off the charts, not only tank troops.

As for the saboteur, it has enhanced its long-range ability, in addition to being able to spray poisonous fire bombs and breath, it can also fire terrifying steel needles with poison and insect eggs, which are extremely powerful, can penetrate armor, and have strong penetrating power.

In order to make up for the lack of charging ability, Li Yao also built a nest of jumping insects, which is an ace class, but the low cost surprised Li Yao, and one energy unit can create five jumping insects.

This jumping insect attack baptism has a strong bounce ability, which is more practical than a charge, and has a scythe forelimbs and sharp teeth, which can easily kill vulnerable opponents.

It's a pity that the vitality is not strong, the armor is weak, and it is easy to kill, even after being smelted by steel, it is still difficult to change this shortcoming, but the smelting also further strengthens their ability to attack wildly, which is even more terrifying.

Li Yao's mental positioning for them is that it is an assault force, cheap and efficient.

Their powerful jumping ability allows them to jump to a height of nearly 100 yards and then cover thousands of yards to avoid engaging the opposing vanguard tank force and attacking the opponent's weak spots.

And it will work wonders with pit worms.

In order to further strengthen the capabilities of the Air Force, Li Yao's has once again established a number of new nests to produce Hive Lords.

The Hive Worm Lord is a flying unit like a ray and a formidable siege unit, spitting out xenomorphs that can besiege targets and wreak havoc on buildings.

But like the jumping worms, the Hive Bug Lord has a strong attack but a weak defense. Although the hopper is a feared tank class, it is restrained, but it has the ability to jump.

But the Hive Worm Lord is different......
