National Doomsday: I am the master of viruses, I evolve by eating poison

....................

The Night Demon leader's treasury was filled with black gas as soon as it was opened.

Su Yunfei observed cautiously for a moment, but nothing scary came out. Instead, he received a system prompt:

[You get S-level Dark Night Crystal x 2! ]

[You get S-level virus 'Dark Night Demon'! ]

[You get a worn-out doll x 1! ]

[……]

The first two items were quite decent, and the rest were some messy little things.

Su Yunfei checked the information of the first two items.

[S-level Dark Night Crystal]:

It is formed by the evil air at night and is a must-have for the Night Demon clan to improve their strength.

(Note: 500,000 energy points can be extracted)

[S-level virus Dark Night Demon]:

The Night Demon clan has used various monsters for a long time, and a special virus has been formed. It is consistent with the characteristics of the Night Demon and its strength increases greatly at night.

"This Dark Night Crystal..."

Su Yunfei originally wanted to extract it into energy, but then he changed his mind and decided to forget it.

Crystals can be converted into energy, but energy can no longer form a special crystal.

Put it aside for now. It won't run away anyway. What if it is used again?

As for the Dark Night Demon Virus, it sounds quite interesting.

If it is assigned to zombies, their strength will increase greatly...

He will practice it when he has time.

Su Yunfei's eyes fell on the last gadgets.

Among them was a blond and blue-eyed doll, which was life-size.

How could this thing appear in the Night Demon leader's treasury?

It really puzzled him.

Is this the Night Demon leader's ideal type?

"I didn't expect that you are such a Night Demon..."

These small things and fragmentary materials were not of much value, so Su Yunfei took them out.

The S-level Dark Night Crystal was still placed in the Night Demon leader's treasury. Once it was closed, the black gas would not come out.

The black air before also quickly merged into the night.

After counting the rewards, Su Yunfei smiled slightly and began to arrange the base with great expectation!

He donated all the low-level materials that he could not use to the base warehouse.

Then, the leader's announcement was issued in the area:

"Prepare to upgrade the base to E level!"

"Everyone tidy up your own residence. There are two things to do -

First, improve the internal furniture and buildings, the minimum standard: one bed, one table, one chair, one kitchen and one bathroom;

Second, submit the corresponding upgrade materials according to the system requirements."

Upgrading to E level is not difficult. Anyway, the system requires it. Just meet the conditions.

This was the first time Su Yunfei issued a leader announcement, and hundreds of people responded immediately:

"Got it, boss!"

"Thank you for taking the first kill of the leader monster, so that each of us can get an E-level builder~"

"Boss, will there be a new villa area after the base is upgraded? What will the price be then?"

This question...

Su Yunfei thought for a while and responded:

"There will be a new villa area. The foundation price remains unchanged, and the houses need to be built by yourself.

If you already have a place to live, you can sell it to the base or other members."

After answering a few small questions, Su Yunfei went to the vicinity of Villa No. 20.

With the labor of a group of A-level builders, the high-tech agricultural production base there has also been fully formed.

Zheng Guyu was checking the situation inside. When he saw Su Yunfei coming, he ran up and said, "Hello, leader!"

Su Yunfei nodded.

This guy is really devoted to farming. Even in the beast tide and material activities, he can still maintain daily agricultural output!

Now there are a bunch of agricultural products in Su Yunfei's system space. The space has a 100% preservation effect, which is great.

Su Yunfei opened the treasure chest just now and got 100 soilless cultivation sets, as well as 6 kinds of spiritual medicine seeds with 500 seeds each, and traded them to Zheng Guyu, saying:

"Farming is secondary, and growing medicine is the future. You study it."

Although it is a D-level spiritual medicine seed, it is also a rare item that has never appeared before.

It is just right to accumulate experience in growing medicine.

By the way, after the medicinal materials are mature, they can also be used to practice for the pharmacists in the base.

Zheng Guyu nodded repeatedly and promised to complete the task successfully.

Su Yunfei also set up some trusteeship in the system-

The system can use E-level to A-level materials in the system warehouse as a leader;

When the base reaches the E-level upgrade standard, the system will automatically start upgrading and automatically use the S-level construction team summoning scroll.

After arranging everything,

Su Yunfei went home, sat on the futon in the training room on the top floor, held the S-level Pure Stone in his hand, and began to absorb the SS-level spiritual crystal he had just bought!

Good posture, just about to start practicing, Su Yunfei suddenly thought of a question and asked the system:

"Will the energy contained in the SS-level crystal exceed my tolerance?"

[You can stop absorbing when you feel uncomfortable, and the energy in the crystal will not dissipate! 】

"Okay."

Su Yunfei began to absorb with confidence.

Swish!

At the beginning, he felt comfortable as if he was soaked in hot water.

Gradually.

It was like an invisible cool stream, pouring into his mind, converging with his original mental power.

He felt that behind the stream was a vast sea.

In comparison, his mental power was like a small puddle.

In this case, it is even more necessary to absorb the mental crystal well...

Time flies.

In the blink of an eye, 6 hours passed.

Su Yunfei slowly opened his eyes, his eyes were like lightning!

The SS-level mental crystal had completely disappeared and was completely absorbed by him.

He hadn't slept for almost two days, but he didn't feel sleepy at all. He just felt refreshed and energetic.

Even more energetic than the spirited boy.

He looked at the system prompt again.

[You absorbed an SS-level spirit crystal, and your spirit attribute increased by 2600 points! ]

[The current spirit attribute is 3230 points! ]

"Too scary!"

Su Yunfei's eyes were bright and shining like stars.

The attribute points increased by 2600 at once, and he was a little excited.

Of course, this was also because of the equipment, which brought additional bonuses.

Otherwise, using only one crystal would really be a disadvantage.

However, after taking another look at the description of the spirit crystal and thinking carefully, Su Yunfei's mood slowly became heavy again-

If the 2.5 times bonus is not calculated, he has absorbed a total of 1040 spirit attributes.

The system said before that according to the degree of absorption, the minimum spirit attribute can be 1000 points.

"It turns out that I am a poor student!!!"

Su Yunfei was hit a little bit.

But at the same time, he also became curious. What determines the degree of absorption?

Spirits should also have different qualifications!

How is this determined?

How is the level of mental power evaluated?

System answer:

[Mental power evaluation needs to be opened through a special building "Dojo"! ]

[When the base is upgraded to D-level, you can build a dojo! ]

"Okay!"

Although I am a poor student, I have a bonus!

Su Yunfei didn't bother about it. The most urgent task was to upgrade the base to E-level first, and then build a martial arts gym!

He immediately checked the system log.

During the time he was practicing, a lot of things happened in the base and the area.
