The cost of being promoted to the 20th level blood crystal space is about 800 billion.

This is a huge burden for the accumulation of blood semen that Li Feng had before. Therefore, Li Feng has never been in the level of promotion space, but instead focuses his focus on the female insect.

However, now, since the personal absorbing special features is not enough, and the total accumulation of blood essence is almost reaching 150 trillion units.

These 800 billion blood sperm units are naturally not considered to be consumed.

It was not said that since there was a lack of special space bars, Li Feng immediately issued a promotion order to the space without thinking.

"Tip: To upgrade to the level 20 blood crystal space, it will cost 819.2 billion blood sperm units. Will it be upgraded?"

"yes."

In just a moment, Li Feng discovered that his total blood semen accumulated, and more than 800 billion were deducted.

However, the blood crystal space has undergone a series of changes at this time.

The blood crystal space at level 20 has expanded from the original 190 meters diameter to two hundred meters.

Although according to the data ratio, this only expanded ten meters from the original diameter.

However, as long as people who are slightly sensitive to the area will know that when the area becomes larger and larger, even if the diameter distance of ten meters is increased, the actual total area is definitely very considerable.

A blood crystal space with a diameter of 190 meters is calculated carefully and only 36,000 square meters is included.

However, the blood crystal space with a diameter of 200 meters is directly accumulated in 40,000 square meters, which is 4,000 square meters more, accounting for one-ninth of the original area. It can be seen that this blood crystal space with a diameter of only ten meters is more. In fact, it is indeed much larger.

Four thousand square meters, if calculated based on the housing area, one hundred square meters per household will be enough to accommodate forty families.

In addition to the expansion of the space area, the additional benefits are also the distance between the blood crystal space collecting and sensing blood essence. It rose from the original 1,900 meters to two thousand meters.

The diameter of the transmission elevator also rose to twenty meters.

In addition, the most intuitive thing is that, for example, the additional success rate per day in the synthesis box function also increased from 19% chance to 20%.

Li Feng personally raised similar demons, etc., and the number of them has also increased one after another.

However, the above benefits are not the focus of Li Feng's promotion space level this time.

The only point is that Li Feng lacked a special vacant space bar that he had a headache before, and he was finally qualified to buy another one again.

"Congratulations, the Blood Crystal Space has been successfully promoted to level 20. You have obtained the purchase of the seventh special-level vacant space column. The next level and the 21st level space level need to be promoted to the blood semen unit is 32,760 billion. Please continue to work hard and continue to work hard..."

When Li Feng received a series of congratulations. One of the above messages, he knew that the things he had been having a headache before were completely solved.

In the series of Magic Strength, every fifth level is one major level, and the level of space is also promoted by five, with natural, every five levels. Blood Crystal Space will have new abilities.

Yes.

The addition of a new purchase space bar is just one of them.

The blood crystal space at level 20 did not disappoint Li Feng this time, and it did indeed add a new elemental ability.

"Congratulations, your Blood Crystal Space has been successfully promoted to level 20, and you have obtained the authority granted by a deputy commander."

When Li Feng received the information from the deputy commander's authority, he couldn't help but pay attention to it several times immediately.

It turns out that this is a power to appoint the second commander.

Simply put, with Li Feng having this authority, he can finally openly and set up a character to replace him when it is inconvenient to manage the entire Blood Crystal Space.

In fact, Li Feng actually has similar powers in the space of the level 20 blood crystal.

For example, if you order a large area of ​​the blood crystal space to open the inlet and exit. For example, if you open a certain subordinate, you can use the transmission elevator of the blood crystal space.

However, the above details are shared and open instructions, and everything can only be enjoyed, and it does not really allow you to fully control the entire blood crystal space. The permissions are actually very limited.

But now the authority to grant this deputy accusation is very different. This can give the function of the entire blood crystal space to the deputy commander to control and manage.

For example, its permission does not only refer to allowing open enjoyment to someone and a certain cluster, but also allows designated deputy commanders to control the development of the entire space.

The level increase permissions of the blood crystal space, the permissions of the use of synthesis functions, and the command rights of all demons and mother insects, etc.

In addition to being unable to raise the demons at will with Li Feng, the ability to raising the demons at will, is basically included.

It has to be said that the emergence of this deputy command authority made Li Feng quite concerned.

In this case, it will solve the problem that if he is not on Earth in the future, he will at least have a deputy who can use the power of the blood crystal space.

But the question arises again. Who should this deputy commander give to?

Several characters flashed through Li Feng's mind, including King of Soldiers, Morris, Ling Qian, and his wife Liu Ruoshi.

However, now that the King of War has passed away, only these three people are left, who are particularly important to Li Feng.

Her daughter-in-law Liu Ruoshi probably doesn't want to get too involved in this aspect, and the remaining candidates are Morishan and Ling Qian.

"Well... I'll talk about this later."

After thinking for a while, Li Feng still had no ideal result. According to his comprehensive ability, this deputy commander candidate must be Morishan, because of his comprehensiveness, Morishan is more stable and more overall.

However, Mount Mori is also an important figure in the Blood Moon World. If you hand over this authority to Mount Mori, it means you cannot play too much role in this deputy commander.

After all, now Li Feng has almost put his focus on the Blood Moon World, and no one takes care of the situation on Earth.

After thinking about it several times, before making a decision, Li Feng simply planned to put it aside and focused on the level of the blood crystal space again.

"Are you still going to level 21?"

This problem arose in Li Feng's mind. If you only upgrade to one level, you will not change much. If you can upgrade to the 25th level at once, it will be different.

Soon, he quickly calculated the total cost of upgrading the blood crystal space from level 20 to level 25, and calculated it by increasing it by five times per level. The final answer was that it was to upgrade to level 25 blood crystal space. It actually took a total of 26 million trillion.

It's okay if you don't calculate it, but you're shocked yourself. Damn, the 21st level is only more than 3 trillion yuan. For Li Feng, who is now 150 trillion yuan, it's not considered a drizzle, but it's still easy to afford it.

Level 22 is only 15 trillion, and it can also be afforded.

But the problem came soon. When the cost of level 23 was consumed, it suddenly turned into 75 trillion yuan, which was almost half of his current net worth.

The twenty-fourth level is even more exaggerated, and it is directly more than three hundred trillion.

"Ma, this is so poor."

Li Feng suddenly realized that after he had developed for so long, the speed of blood semen collection has increased a lot, but in the end, whether it is to promote the higher level of the demon or the mother body, or the increase in the blood crystal space to the higher level, it is still difficult to make progress.

For a moment, he was so miserable.

The higher the level of the blood crystal space, how does it feel more difficult than imagined? And it is getting more and more difficult, so difficult that he has been busy for a year, but he can only increase the blood crystal space by three levels?

"Will you go the wrong way?"

At this moment, Li Feng was indeed deeply in a deep reflection. If the blood semen collection speed is now full of insect farms all over the world, and he is still developing at a very slow pace, how should he collect more blood semen in the next step?

Moreover, this fast collection effect will definitely not be simply doubled, or doubled, and it is easy to issue it. It is necessary to make a big leap. Otherwise, with the current collection effect, even if the progress has been improved several times, it is still a big problem to collect the requirements of tens of trillions of upgrades that require dynamic slaughter.

Gradually, as Li Feng reflected, he felt more and more that he had missed something. It was probably a more effective way to collect blood semen, but he probably didn't find it.

Otherwise, why hasn't he ever seen the two extra reward items he received since he obtained the blood crystal space and gave excellent evaluation speed for blood essence collection?

The reason is naturally that, for a long time, there have been many opportunities for extra items to reward the total accumulation of blood semen, which have been denied by the blood semen collection speed that I cannot keep up with.

The blood crystal space is probably very unqualified for the speed and efficiency of collecting blood essence.

Thinking of this, Li Feng felt so depressed.

The more he thought about it, the more he felt that he had definitely not discovered a faster method of collecting blood semen, which was definitely.

Shaking his head, thinking hard for a while but still failed, he could only put aside this big problem for the time being.

Unexpectedly, it was not a solution to keep thinking about it all the time, so he had to return to the main business again.

Entering the Magic Specialty Icon Items, Sure enough, it rose to the blood crystal space at level 20, and there was an activated specialty column inside.

This is the seventh one.

Without thinking, Li Feng directly spent one trillion blood semen to buy the seventh special-element vacancy column that has been activated.

After doing this, Li Feng finally collected all three specialty columns.

"Enhanced speed..."

"Add to enhance sensitivity..."

"Absorbing reaction strengthens..."

After ten minutes passed, Li Feng's strong upper body had three new specialties.

At this moment, he felt that his control over his body had reached its peak like never before, his mind was clear, and his reaction and agility were simply excellent.

Speed ​​enhancement, sensitivity enhancement, reaction enhancement, combat power enhancement. When these four passive enhancements are all integrated into one person's body, what kind of improvement is this?
