After Li Feng led the people away, Chen Jun rode on the steel griffin and led the griffons to the high altitude of the rainforest to start a new round of bombardment.

However, once the novelty has passed, it is a bit boring to repeat it every day, and at this time, Chen Jun has been bombing for five days in a row, watching the steel griffin constantly rising into the air and diving, listening to the constant roar on the ground, but yawning.

Chen Jun, who was really bored, slowly closed his eyes and entered the system interface and saw a glance, after a few days of bombardment, the core value has reached 260,000, and after equipping the remaining people with nano core armor, the metal value is still 14077, and now in general, the metal value is completely insufficient.

Just as he was pondering about this, a sudden prompt sound kept coming from his head.

"The number of high-grade refined steel smelted meets the requirements, all the abilities of the first-level [Metal Core] are unlocked to meet the upgrade requirements, and the [Metal Core] is upgraded to the second-level."

"Due to the upgrade of [Metal Core] to Level 2 and the upgrade of [Metal Factory] to Level 2, unlocking the new ability [Luna Titanium Alloy Smelting], the number of metal factories has increased to 100."

"Due to the upgrade of [Metal Core] to Level 2, the metal life upgrade system is fully unlocked."

"[Primary Scythe Mantis] can be upgraded to the intermediate form [Shadow Hunter], please enter the system interface to view."

Suddenly, this series of prompts that appeared in his mind really stunned Chen Jun, or rather, happiness came too suddenly, and he knocked him unconscious.

After looking forward to it for so long, the [Metal Core] system was finally upgraded to Level 2, and through the prompt sound, Chen Jun also vaguely guessed the requirements for this metal core upgrade, the first should be to smelt a sufficient amount of metal, and the second is to unlock all the abilities and technologies under the first-level metal core, as long as these two points are reached, the metal core can be successfully upgraded.

And what excites him the most is the increase in the upper limit of the [Metal Factory] quota, and this time it has increased tenfold at once, which means that as long as he fills up all the metal factory quotas, then he will get 100,000 metal values a day.

And the last two also mention that the metal life upgrade system is fully unlocked.,There's been no movement since the self-exploding spider was promoted to the intermediate level.,Today this system is finally reopened.。

When you open the system interface, it can be said that it has changed a lot.

[Metal Core]: Level 2

[Metal value]: 14077

[Core value]: 265915

[Metal Factory]: Level 2, Ability: Luna Titanium Alloy Smelting, Quantity: 10/100

[Metal Life]: Production Robot (10 Metal)

Intermediate Exploding Spider (200 Metal)

Beginner Scythe Mantis (200 Metal Value)

Elementary Sky Eye (100 metal)

【Life Evolution】NH-1 Potential Stimulation Liquid (100 Core Value)

[Weapon Technology]: Light Individual Laser Gun (100 Metal)

Engine Weapons (1000pts)

[Integrated Technology]: Short-distance transmission matrix (1000 metal value)

War Beast Fence: ( 10000 core, 100000 metal)

Gravity Training Room (10000 Metal Value)

[Mechanical Armor]: Nano Core (1000 Metal)

[Exclusive Mechanical Armor Form]: Iron Knight

Now that the level of the system and the metal factory has become level two, and a new metal smelting ability has been unlocked, the Luna titanium alloy, just by listening to the name, you can vaguely guess that this metal must be much stronger than the high-precision steel produced by the first-class metal factory.

These are not the most important things, the most important thing is that Chen Jun has always relied on the killer weapon [Scythe Mantis] can finally be upgraded.

At this moment, Chen Jun couldn't wait to check the upgrade information about the Scythe Mantis.

[Beginner Scythe Mantis]: Can be upgraded to the intermediate form [Shadow Hunter], unlocking the upgrade requires 1000 core points, is it upgraded?

For the time being, the most important thing Chen Jun lacks is core value, so he chose to upgrade without hesitation.

"The upgrade is complete, and you will get a new metal life [Shadow Hunter], please enter the system interface for details."

At this moment, the name of the primary scythe mantis on the system interface has disappeared, and the words "Shadow Hunter" have been replaced by the words.

[Shadow Hunter]: A hunter who hides in the shadows, a ruthless reaper of life, after upgrading, the concealment ability is strengthened, shortening the appearance time when attacking during the day, and will not appear when attacking in a dark environment; Movement speed has been increased, the primary weapon Scythe has been upgraded to a high-vibration particle blade, which can easily cut through high-precision steel, and the destructive ability has been enhanced, and summoning costs 500 metal.

This is the first time Chen Jun has seen such a long text introduced in the system, and after reading it, Chen Jun knows that this time the Scythe Mantis, which should now be called the Shadow Hunter, is really awesome.

Now that he didn't have the heart to continue bombing, he ordered the Iron Gryphon to fly back into the pens, and upon landing he summoned a scythe-blade mantis from the metal life space.

The upgraded Shadow Hunter's body size has not changed much, it is still about half a meter long, and it has entered a hidden state under Chen Jun's order, and a vague and transparent outline can be vaguely seen in the hidden state when it is in its primary form, but after the upgrade, this vague outline has also become very shallow, and only when it is very close and the Shadow Hunter moves, a little transparent outline can be faintly seen, and it is almost completely invisible when it is stationary.

At this moment, Chen Jun gave the Shadow Hunter the order to attack the thick metal of the neck of the beast pen, only to hear two crisp sounds, half of the metal strip fell to the ground, Chen Jun picked up the metal strip and took a look, the incision was extremely smooth and flat, like tofu cut by a steel knife.

The evolved high-vibration particle blade is like cutting tofu, which shows the power of this cutting blade.

Now Chen Jun's heart couldn't help but be full of anticipation, the intermediate form of the sickle mantis was already so terrifying, so what would the advanced form, or the higher form of the sickle mantis, look like?

Through the energy transmission matrix back to his own metal smelting plant, his main task now is to fill the quota of 100 metal factories in the shortest possible time, and now the management of hundreds of metal smelters around is in the hands of Kuka, if you want to get the management right, you can only find Kuka again.

At this moment, Chen Jun didn't know the bottom of his heart, and he didn't know if he would give him the management rights of 90 metal smelters when he opened his mouth, but he really couldn't do it, so he could only find another reason to trick him into forcibly obtaining the management rights of these metal factories with his mind control ability, metal factories are the key to development, and he must get them.
