I have to say that Ye Bing's mood is quite good at the moment.

Just now, he was still thinking about how to balance the energy consumption of the expanded mechanical troops, but then, this problem was successfully solved!

He laughed and praised:

"Natasha, well done!"

Natasha is still in that calm tone:

"In order to upgrade the auto-charging technology to the next level, I used some of my reserves."

Ye Bing was stunned and asked, "Reserve materials?" Uh, you mean the high-grade magic crystals I kept? ”

"Yes."

After hearing the affirmative answer, Ye Bing's heart couldn't help but tighten.

He cautiously asked, "How much?" ”

Natasha said blandly:

"Five normal-quality magic crystals."

"Oh, that's good......"

When Ye Bing heard this, he immediately patted his chest relaxedly.

As long as the green shard wasn't used, he would be able to accept it.

Speaking of which, it is also thanks to Xu Yu's help before.

If he hadn't provided a lot of blue magic crystals, the point in Ye Bing's hand would have been just enough for the base to complete the upgrade.

And now, not only has the base been upgraded, but various advanced technologies have also developed a lot, thanks to Xu Yu!

As for when will the higher-grade gene enhancement liquid be brought to others......

Ahem, there's no rush for the time being.

As long as the team develops, will you still worry about the high-level magic crystal?

Of course not!

But......

Ye Bing hesitated for a moment, but still asked:

"Are there any blue crystals left?"

Natasha quickly replied:

"Two more."

Ye Bing slapped the table excitedly. shouted:

"Hahaha, God help me! Hurry up, let's upgrade the tech tree. I'll be able to make the LV2 Gene Enhancement Liquid sooner, I'll be waiting to use it! ”

“…… Good. Natasha replied lightly.

It is estimated that if Natasha has emotions, I am afraid that she will have to scold this guy for being shameless at this time.

An hour later.

When a newly baked genetically enhanced injection was held in the hand of a machine engineer and placed in front of Ye Bing's table, his whole body was almost enthusiastic!

He impatiently took the injection needle and put it in front of his eyes, and said with a smile:

"Is this the genetically enhanced injection of LV2, this color is really deep!"

Indeed as he said.

Maybe it's something to do with the liquid color of the crystal itself.

LV1 Gene Enhancement Injections are white. The liquid in it is no different from the characteristics of normal saline, except that it is thicker.

But at LV2, the color changes to a rich deep blue.

It's as if you've been stained with blue ink.

Ye Bing looked at this injection with some fascination. He didn't expect that. He would have gotten this thing he had been looking forward to for a long time so easily today.

For this reason, he only paid 35 energy for the technology tree upgrade, 20 energy for LV2 technology upgrade, and 20 energy plus 2 blue magic crystals for the production cost.

In total, it adds up to less than a hundred energy!

This made Ye Bing a little happy for a while.

With a sense of excitement and joy. Ye Bing played back and forth for a while. In the end, I chose to put it down for the time being.

He was afraid that if a needle was injected, he would become unconscious again.

Therefore, it is better to inject at night before going to bed.

Before that, it is necessary to use the daylight time to study the new features of the base.

……

About three hours later.

Ye Bing had a happy and tired expression on his face, and slumped in the command chair.

At this time, he had already understood all the characteristics of the new base, and the thoughts in his mind were extremely clear!

"It's so strong. It's really strong......"

After a few minutes of rest, he bounced back up from his chair.

"Okay. Time waits for no one, and the next step is the main part! ”

He stood up and ordered:

"Bring all the loot you caught before!"

Not long after the words fell, one after another sappers walked in outside the door.

Each sapper had some weapons in his hand, including knives, daggers, fist gloves, and even a lot of rifles, and even the dark green shield used by the flat-headed male dragon before!

The above weapons, without exception, are all enhanced energy-based weapons!

These weapons, which originally belonged to the core members of the major forces, were all owned by Ye Bing after they were killed or seriously injured in battle.

Roughly counted, the total number has reached more than 30, especially fists and firearms, which are the signature weapons of the Yilong Gym and the Black Snake Army. In the previous melee, these two teams had the largest number of deaths, and the captain either died or defected, and suffered heavy losses.

When he looked at these weapons again, Ye Bing's eyes were no longer unfamiliar.

In the hours before, he had put all these weapons into the forge and analyzed them.

Today's forging factory has also been upgraded to the highest grade LV2.

After upgrading to LV3, there is one more function in it-

Quenching.

Speaking of tempering, we must first talk about the rating of weapons.

Each weapon, after a comprehensive analysis by the forge factory, will receive a rating.

They are E, D, C, B, A, S.

These six ratings, from low to high, represent the level of the weapon's capabilities.

According to Ye Bing's understanding, its main rating criterion is lethality, that is, the more lethal the weapon, the higher the rating.

But in addition to lethality, the rating also takes into account some other attributes.

For example, whether the weapon is practical.

How good value for money.

Functional conversion efficiency.

Robustness.

Wait a minute.

In fact, the rating system is not a mechanism unique to the LV3 main base.

As early as the time of the main base LV1, a rating system was introduced.

The evidence is that the corpse sword that has been inserted in Ye Bing's waist.

This thing, when it was first produced, was given a rating by the system -

Grade E.

This means that, in terms of overall capabilities, its level can only be ranked among the lowest among many weapons.

It's been a month or two since then.

In the past two months, Ye Bing has been using all kinds of materials to strengthen the corpse sword.

Therefore, when Ye Bing put the Corpse Sword into the forging factory for testing again, the rating he got became-

Grade E.

Yes, or E-class!

At the beginning, Ye Bing was also half angry, and almost didn't spit out a few mouthfuls of old blood.

After all, so many precious materials, including the claws of the second-order mutant Tibetan mastiff, the claws of the second-order cat demon, and the sharp nails of all kinds of first-order zombies, were all taken and integrated into them by him, and in the end, he still got the lowest evaluation, how could he not be sad!

It is estimated that even if the claws of the mutant Tibetan mastiff are re-forged into a sword, the rating will be enough to reach the D rank!

Of course...... The idea can only be thought of.

If you want to forge a weapon, you need a lot of materials. The claws of a mutated Tibetan mastiff alone are absolutely not enough. At the very least, it would take dozens or hundreds of Tibetan mastiff claws to forge a pure Tibetan mastiff weapon.

Even so, after spending so many materials, the result was still so unsatisfactory, which also made Ye Bing depressed for a while.

With an attitude of not admitting defeat, he studied the forge for a long time.

In the end, he really found out what the problem was! (To be continued.) )
