After research, Ye Bing found a problem.

That is, the reason why the Corpse Sword can't enter the D-level or higher is because it is not an energy-based weapon.

And as long as it becomes an energy-based weapon, its lowest rating can also reach D!

So, how do you turn the Corpse Sword into an energy weapon?

Very simple.

Under the refining function of the forge factory, there is a sub-function called "Advanced".

Once the Forge's inspection has concluded that there is a probability that the weapon will be directly advanced, the advanced function will be used.

In the case of the Corpse Sword, the cost of advancement is not particularly expensive.

Twenty-three points of energy, plus seven white crystals, for a total of thirty points of energy.

The success rate of the advanced reaches 98.3%, and basically as long as you choose the advanced, you can complete the progression.

This is inseparable from his previous efforts to fill in the essence.

However, despite this, Ye Bing didn't have much interest in advancing now.

There are two reasons for this.

For one, he is currently only at the level of the Awoken One. Once the LV2 Gene Enhancement Injection fails to progress to Gene II, and he doesn't have a weapon in his hand, it will become very bad.

Second, he already has enough D-class weapons in his hands at the moment, and he doesn't need to have another one.

Those D-class weapons, of course, were given by the invaders of the major forces.

With a total of more than thirty D-class weapons, there is no need to create new ones.

In contrast, Ye Bing was even more amazed by another thing.

After the analysis of the forging factory, the sword that originally came from Uesugi was too long and long, and its rating was actually ......

Class C!

This is the only weapon in the long pile of loot that reaches the C rank.

Even the tragic ghost Li Xuanhuan, who was killed by a laser from the beam tower. The gloves he uses are just ordinary D-class!

This discovery surprised Ye Bing for a while.

Originally, he was not interested in the weapons produced by Xiao Ri/Ben, and the initial idea was to wait for the time to be about the same, and directly throw it to Sawyer to use, and then use something else himself.

But look at the current posture......

Hehe, since Xiao Ri/Bendu has already sent the treasure knife to us. You don't have to use it, right?

His eyes fell on the great long light, and he picked it up easily.

It feels very good, not light or heavy, and is just right for wielding.

The weapons that come from the hands of the ancient swordsmiths of Japan and Ben are truly extraordinary.

In the warfare of ancient human beings, due to the absence of hot weapons, the biggest reliance was only on cold weapons such as swords.

Because of this, the swordsmiths have been exploring for a long time. Gradually, he found a variety of secrets to making weapons strong and sharp.

According to legend, some famous sword-casting masters in ancient times, such as Ou Yezi, the cadre Mo Ye, and Candle Yongzi, slashed the world with swords, and looked at him!

It's a pity that these sword casting secrets. It has gradually worn out in the long river of history.

Ye Bing has always felt that although modern people's technology is far stronger than that of ancient times. However, there is still a big gap between the cold weapons cast by it and the works of ancient swordsmiths.

Intuitively, he thought it was a mental difference.

Although until now, he can't be sure. But judging by the rating given by the forge factory, it is indirectness that proves his point.

Looking at it, Ye Bing couldn't help but sigh.

How he feels now. It's like lying in a mountain of gold and silver, full of wealth, but you can't spend it.

He said to himself: "But it doesn't matter, as long as Lao Tzu also enters the sequence of the second segment of the gene, you can use any of these weapons if you want to use them." You have to touch them all one by one! ”

After understanding the forging of weapons, Ye Bing had a clear idea of the future development drive in his mind.

First, expand the mechanized corps and strengthen armaments.

Second, clean up and arrange several areas around the Doomsday Base.

Third, expand the New Territories army and make the human forces bigger and stronger!

Then, the first thing that should be arranged is the strengthening of armaments.

Ye Bing lowered his head and thought for a while, then gave instructions to Natasha:

"I'm going to upgrade the mechanical barracks!"

Natasha's voice came immediately:

"Yes."

As soon as the words fell, the mechanical barracks at the main base were once again enveloped in a cloud of white light.

During this waiting time, Ye Bing opened the map and began to look at the surrounding area.

With the prompt of the digitized range of the Doom Base, a large area in the vicinity has fallen into the control range of the Doom Base.

Among them, the old and new security zones together account for only three-quarters of the digitized scope of the Doomsday Base. In the lower right corner of the map, there is another area that is within the radial range of the Doom Base, but has not been liberated.

Therefore, Ye Bing's attention was first focused on that area.

As far back as he can remember, there didn't seem to be too many residential buildings in that area, and there were no large shopping malls around, but there were a few prestigious electronic cities.

Judging from previous experience, the number of zombies it contains should not be more than two thousand.

Thinking of this, Ye Bing's heart felt some more hope.

This is the first time he has confidence since the second catastrophe, and it is also the first time that he has taken the initiative to jump on a group of thousands of zombies as the object of action!

In the past, in the face of a group of zombies with more than two hundred, they had to retreat, and it was simply incomparable.

As long as your own troops are sufficient and your combat effectiveness is full, you should be able to deal with 2,000 zombies in more than half a day.

Even if you count the time to recover the zombies, one day is enough time anyway.

Then, after completely clearing the territory around the base, it's time for the crucial third step!

Ye Bing lowered his head and thought for a while, then suddenly asked:

"Natasha, can anything that is within the scope of our base be digitized?"

Natasha replied:

"Yes, commander, they can not only be digitized, but already have been digitized."

"Already digitized?" Ye Bing was stunned for a moment, and then asked, "So, does that mean that we can transfer those things at will, or even destroy and revoke them?" ”

Natasha replied, "To a certain extent, yes. I would like to remind you that most of the things that we digitize are lifeless. And even if something has been digitized, there is a certain price to pay if you want to change their state. “

Ye Bing asked cautiously, "What...... What if I wanted to make an ordinary ten-story building disappear or move its location? ”

Natasha replied almost without hesitation, "3 energy costs." ”

"Huh?"

Ye Bing screamed, and his heart was completely bottomed.

With this bit of energy, my brother can still afford it! (To be continued.) )
