Where the Zerg's nest is located, in the space thousands of meters underground, Wang Jin is looking up to make a lookout, and in front of him is a cone-shaped behemoth that is three thousand meters high and covers an area of more than ten square kilometers, which is the fourth-level mother nest that has been hatched.

In addition to the further increase in size, the whole body of the brood is covered with a layer of pitch-black hard insect shells, and thousands of 100-meter-long dark red cannon barrels extend out, making the brood look like a giant hedgehog.

At the very top of the brood's conical body, there is also a large hollow hole, which also looks like a cannon muzzle, but it is dozens of times larger than the caliber of the barrel in other places.

In addition, the base of the brood grows densely packed with waist-thick tentacles, each of which is more than a kilometer long, and there are as many as 10,000 of them.

"Ding! Level 4 brood hatched! ”

Wang Jin's mind sounded a hint of the brood's intelligence, and at the same time, a series of attributes about the fourth-level brood also unfolded in front of Wang Jin.

New class of Tier 4 Brood:

Metal Devouring Worms: 300,000 silica ore and 120,000 gas mines, metal devouring insects are the products of the insect swarm that once fought against scientific and technological civilization and used disk worms to transform them, and their only role is to absorb all kinds of metals in a large area, reduce and absorb their kinetic energy, and protect the safety of the insect swarm's attack.

Crack Destroyer: 10,000,000,000 silica ore, 10,000,000 gas ore. The Destroyer of Fungi is a kind of Zerg with a mass destruction effect, they can fly freely for more than 3,000 kilometers like missiles, and can also be carried on the host, the fourth level brood, and the Corrupted, self-detonating on the target landing point, releasing fission mycelium, causing devastating damage to organisms, buildings, metals, and vegetation, with a lethal range of up to 20 kilometers, comparable to a human nuclear bomb.

Zerg Brood: Currently level 4. It can provide 500,000 larvae per day, which can evolve all Zerg troops into Level 4 Zerg. The fourth-level brood has the ability to fly in the planet, has super attack and defense capabilities, and is covered with 1,200 3,000 mm corrosive cannons and a 10,000 mm energy main gun, which can carry out fierce artillery bombardment and suppression on the enemy's sky, ground, and bottom of the sea.

The fourth-level brood also has tens of thousands of tentacles, and the tentacles are super tough and soft. It can destroy close aircraft, defend against enemy attacks, and protect the main body of the brood.

After upgrading the level 4 brood, hatching Zerg through the production of brood larvae will reduce resource consumption by 60%. Upgrading the brood to level 5 requires 30 billion brain cores and 20 billion crystal nuclei. ”

The fourth-level base can have 100 insect generals, and currently has insect generals: 50 (insects will be a powerful individual combat unit, the first-level basic worm will need 10,000 brain cores and 1,000 crystal nuclei, the first-level blade queen needs 100,000 brain cores and 10,000 crystal nuclei, and the first-level insect queen needs 100,000 brain cores and 10,000 crystal nuclei, both of which are unique and cannot be built repeatedly.) The first-level worm will be upgraded to the second-level worm, which will consume 5 times the original cost, the second-level worm will be upgraded to the third-level worm, which will consume 7 times the second-level cost, and the third-level worm will be upgraded to the fourth-level worm, which will consume 10 times the cost of the third-level. ）

Psychic Lair: The second-level brood has a special building that can collect the spiritual power of intelligent creatures, which can be used by the Zerg host and insect general, and after upgrading the fourth-level brood, the daily efficiency of the psychic nest will increase by five times.

Fungus Blanket: After the mother nest is upgraded to level 4, the fungus blanket not only delivers nutrients to the insect colony and replenishes the energy of the insect colony to treat injuries, but also has the ability to absorb geothermal energy into silica ore and absorb light energy into gas ore, and can also supply the nutrient bacteria ball to plants and animals, which can increase their production and growth rate very quickly, and the efficiency of the fungus blanket will increase by three times after the fourth level.

This is the situation after Wang Jin is upgraded to level four, although there are only two new types of troops, but each new class is very suitable for Wang Jin, and it can also make the Zerg's strategic strike ability infinitely higher.

"Hatch a metal devourer, a cleavage destroyer."

Wang Jin couldn't wait to meet these two new troops.

"Order received, hatching."

Half an hour later, two new troops appeared in front of Wang Jin.

The metal devouring insect is about 300 meters in size, has no head or legs, and is a mountain of flesh that rolls forward.

On the exterior of the metal devouring insect, there are black spots and protrusions, which constantly change color over time, making the metal devouring insect become colorful and dazzling to look at.

Untie the watch in the left center, Wang Jin controlled the metal devouring insect to let go of the taboo, as soon as the order was issued, Wang Jin came from a strong force in vain, and the watch held by Wang Jin in his hand was pulled by an invisible suction, wanting to move towards the metal devouring insect.

Fortunately, it is Wang Jin who is holding the watch now, and he has infinite strength in his body, so he can withstand the pull of the metal devouring insect, and if he changes someone, he will not let go to ensure that even people have to fly over.

Feeling the strength of this pull, Wang Jin let go of his palm, and without restraint, the watch was immediately sucked by the metal devouring insect with a whoosh, and flew up quickly, making Wang Jin stay for a while. (To be continued......)
