At first, Su Chen hadn't noticed, but after he took a look at his remaining energy, he almost didn't vomit blood.

It only cost him 400,000 energy to upgrade the super unit to the 7th tier peak. In other words, it takes 100,000 energy to upgrade a person.

System, you are rough, I think we need to communicate

"Master, the more you get to the back, the strength of each level differs greatly, and the energy needed is a lot more, and 100,000 points of energy are already very small." The system was a little aggrieved.

Su Chen thought for a while, it was really such a thing.

Because of the existence of the system, his subordinates only need energy to improve their strength. There is no bottleneck at all.

But humans in this world, every time they rise to a small level, it is estimated that they will be excited for a long time.

If you tell someone that it only takes 100,000 points of energy to make him go from the sixth-order peak to the seventh-order peak, it is estimated that countless people will fight to break their heads.

After doing so, Su Chen suddenly felt that he was making money. What the **** is this?

"Forget it, I don't want to. It consumes a lot of energy. For the time being, it only improves the strength of four super units. Oh, there is a spy."

Su Chen almost forgot the important spy. It was because this guy had no sense of existence. If it hadn't been for the spy to contact him, he himself would have forgotten the existence of the spy.

Seeing that his energy had been reduced by half at once, Su Chen couldn't help sighing.

"Sure enough, the energy is still not enough."

Su Chen had the final say, and next he had to make all kinds of weapons Zhu Hui needed. The energy would be at least several hundred thousand, so that his energy would bottom out.

If he hadn't had several mineral deposits, he would really not be able to sustain such a large expenditure now.

Not ready to upgrade other combat units for the time being, Su Chen set his sights on the lottery.

"What is the difference between this lottery and my level 4 permissions"

Su Chen remembered his Level 4 authority, which was to draw a lottery once a day. He had drawn a lot of combat units from here and saved a lot of energy, which was considered a good ability.

"The owner's level 4 permission lottery is limited to combat units, and this lottery opportunity can draw all Red Alert units, and there is even a small probability that they will be drawn to Red Alert 3 units."

"Really" Su Chen was surprised. He didn't expect that the lucky draw chance this time would be so powerful that even the units in Red Alert 3 would have it.

But when it comes to probability, Su Chen feels like a pit.

Do you still need to say the probability of the lottery? The so-called small probability is almost equal to zero, at least Su Chen doesn't think he can get it.

"Would you like to wait for the time for the possession of the emperor to cool down before drawing a lottery"

A few days ago, Su Chen had already used Level 5 permissions, and it was still in the cooling time. For the first time, he felt that the rule of using once a week was too bad.

"If the owner is willing to upgrade the level 5 authority, the cooling time can be reduced." The system prompts.

"There is still this kind of operation" Su Chen was stunned, he did not expect that the commander's authority could be upgraded.

"Currently the authority that the owner can elevate includes level 2, level 3, level 4, and level 5."

Su Chen recalled the effects of these permissions, and then he frowned, "I can understand other permissions, but how can I upgrade this level 4 permissions? Will I be able to draw twice a day in the future"

"No, after the master is upgraded, the range of draws can be expanded."

"How much energy does one upgrade require"

"According to different permissions, the minimum need is 50,000, and the maximum is 100,000."

Su Chen grinned, it was still the original formula, and the familiar taste really focused on his energy.

System, to be honest, are you Zhou Papi

Su Chen thought about it carefully. Level 2 authority is a kind of ability that borrows from the unit under his hand. It lasts for an hour. If it is improved, does it last longer?

This does not have much effect for him.

"Master, it is also possible that the number of borrowed abilities has increased. This depends on luck." The system reminded it at a very high time.

The corner of Su Chen's mouth twitched, and he was really looking for luck, so he put his eyes directly on the level 5 authority. As long as he raised the level 5 authority to reduce the cooling time of the possession of the emperor, then he could directly Use the possession of the European Emperor for the lottery.

"Upgrade level 5 permissions."

As soon as the voice fell, he found that his energy had been reduced by 50,000, and then he saw that the effect of his level 5 authority had changed. There was no change in other aspects, only the cooling time was reduced from one week to three days.

And now three days have passed since the time of use, that is to say, he can now use Level 5 permissions.

"I didn't expect that luck was so good, and it was done all at once. It seems that I am the Emperor of Europe."

Su Chen smiled contentedly, and directly used Level 5 authority, with Ou Huang possessed.

"Raffle, three consecutive draws"

Su Chen did not dare to use the three chances of the lottery.

"Congratulations, master for getting the giant squid."

"Congratulations, master for getting a dolphin."

"Congratulations to the master for drawing the giant cannon."

In the first two, Su Chen didn't feel much, but the last one made Su Chen's eyes brighten, unexpectedly it was a giant cannon.

This was the unit he had long wanted, but his commander's authority had been insufficient, which made him give up.

"Wait, let me see if the 7th level commander can build a giant cannon."

After Su Chen finished reading it, he was a little helpless. He could really build it. In other words, if he got this thing, it saved him some energy at most.

"Forget it, it's better than nothing, what about giant squid and dolphins, there is no water around here"

The giant artillery is a well-known unit in the red police. It is the best defensive weapon. The shells are powerful. It is estimated that one shot can kill the seventh-order strong, even if the eighth-strong one is hit frontally, it is estimated All get hurt.

The disadvantage is that the firing interval is a bit long and cannot attack enemies that are too close to the cannon. In other words, this is a purely long-range attack weapon.

"Place the giant cannon on a high ground so that the power of the giant cannon can be maximized."

Following Su Chen's order, a tall cannon appeared on the top of a surrounding hill. The muzzle was dark and looked terrifying.

Naturally, the sub-base could not be let go. A giant cannon also appeared, but this giant cannon was built by him with energy.

After getting these things done, Su Chen finally had time to check the units he unlocked with Level 7 permission, but he could not wait long ago.

"Haha, I'm here for spy satellites and Chronicles"

Su Chen opened the interface and saw some original gray patterns on it. At this time, they finally turned into bright colors, and he saw something at a glance. ,, everyone remember to bookmark the URL or remember the URL, the URL, the fastest update for free, no anti-theft, no anti-theft error report chapter, ask for books, find books and chat with book friends, please add qq group 647377658 group number
