"Upgrading to a fifth-level base requires ten fifth-order magic cores and five million energy points, confirm the upgrade?".

Hearing this mechanical voice, Emperor Xiaoyao smiled slightly: "Of course."

"Confirm the upgrade, deduct ten fifth-order demon cores, five million energy points, the upgrade starts, the time required for the upgrade is six hours, please wait."

Looking at the base that was being upgraded, Emperor Xiaoyao didn't stay too long, but just issued an order to the Apocalypse of Fate: "Apocalypse of Fate, after the base upgrade is completed, make all the remaining demon cores into soldiers, and then let them hunt in batches within your monitoring range, the target of the hunt is mainly the second-order to fifth-order demonic beasts, don't provoke the first-order and the sixth-order and above", the first-order ones wait for them to advance to the second-order and then hunt, and the sixth-order ones can't afford to provoke.

"Got it, Your Majesty, there is one more thing I need to tell you, some of the soldiers of the first and second orders have already met the conditions for promotion, do you want to promote them?"

"Oh, are there already soldiers who meet the conditions for promotion? Of course they have been upgraded, but how many energy points are needed to upgrade?", Hearing that there are soldiers who can be upgraded, Emperor Xiaoyao is very happy, but looking back, I still have to check the energy points required for promotion, if it is not cost-effective, it is better not to upgrade.

"Your Majesty, you don't need many energy points to upgrade, only half of them are needed, for example, it takes 20,000 energy points to make a fourth-order soldier, and only 10,000 energy points are needed to upgrade from the third order to the fourth order."

Hearing this, Emperor Xiaoyao's eyes lit up, there was so much less, this can also be used as a big way to be a rioter, create a large number of low-level soldiers, and then advance. "And how many soldiers can advance now?".

"Well, there are three hundred and fifty of the first order, and one hundred and twenty of the second order."

Hearing this, Emperor Xiaoyao frowned, "Why is it so little?"

Destiny Apocalypse heard the boss's complaints, and said helplessly: "Your Majesty, the time is too short, the physical changes of the soldiers cannot change greatly, and these soldiers who can be promoted almost all of them have gone through more than three or four battles to reach the promotion conditions."

Listening to the helpless voice of the Apocalypse of Fate, Emperor Xiaoyao recalled An Jie Silai, this guy has practiced the Star Attraction Technique for several years, and he has not even reached the first order, so you can imagine the difficulty of cultivation, but as long as his soldiers are physically qualified to withstand a certain level of energy, they can upgrade him to that level, for example, if Emperor Xiaoyao's current physical strength reaches the level of energy that can withstand the level of the God Domain, then the base can upgrade him to the level of the God Domain.

And, most importantly, there is no limit to the level of the base for a promoted soldier. Now the base is level four, if it is manufactured, the highest can be a fourth-order soldier, and if the fourth-level base is used to upgrade soldiers, there is no such restriction, you can upgrade to that level, as long as your body can withstand the impact of energy.

"Alas, I'm too greedy, so how long does it take to upgrade?", if the promotion time is long, it is also a big flaw.

"Ascending time is twice as long as manufacturing," Destiny Apocalypse said as his voice grew quieter and quieter, and by the end it was inaudible.

Emperor Xiaoyao frowned, he thought that this was a BUG-like existence, it turned out that there were so many additional conditions. Sure enough, there is no such thing as a free lunch, and if you want to get something, you have to give something that goes with it.

"It's better to be upgraded, anyway, I'm not in a hurry now, but, fate is apocalypse, and there doesn't seem to be such a building in the base."

"Your Majesty, soldiers do not need to be built to upgrade, there is an independent energy channel between the base and each soldier, which can be used to supplement the daily energy consumption of soldiers, and can also be used to transmit the energy needed for soldiers to upgrade."

"Oh, I see, the base is really peculiar, and all of these functions are available." Emperor Xiaoyao once again felt the powerful ability of the base, but he also recalled the past period of time, and he did not see any soldiers go to the base to replenish energy, it turned out to be replenished through the energy channel. However, this energy channel also has certain defects, that is, it can only supplement the daily energy consumption, if there is a war, the soldiers' energy is greatly consumed, the channel can not be replenished in time, and the soldiers' combat effectiveness will also decline. However, with the red and blue potions made by the Forbidden City's potion factory, this deficiency can be compensated. As long as the soldiers store dozens of bottles in their storage rings, they are not afraid that the magic power (cultivated by the magician) or the power of the stars (cultivated by the warriors, referred to as star power) will be exhausted during the battle, and they are not afraid of running out of physical strength.

"The matter of upgrading, you can just watch it yourself, as long as there is something that can be upgraded, I will upgrade him, although the time is twice as long as manufacturing, but the price is only half, which is quite cost-effective."

"Yes, Your Majesty", the fate of the apocalypse respectfully received the order.

.................................................................. After inspecting the base, Emperor Xiaoyao came to the Forbidden City again, it was still so brilliant and gorgeous, majestic, and there was no trace of dust, as if there was a special force that drove all the dust away from the Forbidden City.

Walking into the Forbidden City, Emperor Xiaoyao came directly to the barracks according to his previous habits, and along the way, Emperor Xiaoyao saw groups of soldiers patrolling, these soldiers were not incorporated into the army, they were all first-order soldiers, in addition to daily patrols, it was exercise. Under the respectful gaze of the soldiers, Emperor Xiaoyao arrived at the barracks.

At this moment, a voice sounded in Emperor Xiaoyao's head, "The barracks are full, please host to upgrade or expand the Forbidden City."

The sudden voice startled Emperor Xiaoyao, "Who are you?"

The stiff voice came again: "I am the brain of the Forbidden City, responsible for managing the buildings in the Forbidden City."

"It's a smart brain again, you will be called Zitang in the future, and when there is a smart brain in the future, it will be called confused", Emperor Xiaoyao casually gave it a name, and he didn't care if it accepted it or not.

"Zitang, let's talk about the barracks first", Emperor Xiaoyao found a place to sit down.

"It's such a host, now the Forbidden City is a miniature low-level Forbidden City, there are ten barracks, each barracks can accommodate a thousand soldiers, a total of 10,000 people, now there are about 6,000 first-order soldiers, about 6,000 second-order soldiers, more than 900 third-order soldiers, one hundred and eighty-five fourth-order soldiers, six fifth-order soldiers, and the total number of soldiers has reached more than 13,000, which exceeds the capacity of the barracks, so it is recommended that the host upgrade the Forbidden City or exchange for another Forbidden City."

"Is there already so many?", hearing this news, Emperor Xiaoyao was slightly stunned, not expecting that he already had tens of thousands of subordinates. I still remember that when I first came, there were only four first-order soldiers and five civilian slaves, which was called a poor sour.

And now it can be said that the soldiers are strong. But the problem came out again, the soldiers who were created no longer had a place to live, and as their boss, they naturally had to solve this problem by themselves.

"System, how many energy points do you need to upgrade to the miniature intermediate Forbidden City?", the system only told itself the energy points needed to redeem an entire Forbidden City last time, and did not tell itself other information.

"You need 900,000 energy points, do you want to level up?", the system quickly replied to Emperor Xiaoyao.

"Well, upgrade the Forbidden City to a miniature intermediate Forbidden City, but this arrangement of exchanging energy points is reasonable", the low-level Forbidden City needs 100,000, and the intermediate one needs 1 million energy points, and the difference in the middle is exactly 900,000, which is exactly the energy points needed for upgrading.

The system glanced at him expressionlessly: "Why, you still want to take advantage of me."

"Why, I'm complimenting you on your good math." The system didn't mess with him, but followed the system's procedure, asked him if he confirmed the upgrade, and then after receiving a positive answer, he disappeared.

After the incarnation of the system disappeared, the Forbidden City was covered in a mysterious white light, and even the Emperor Xiaoyao standing in it couldn't see how the buildings around him had changed.

The white light didn't stay on the Forbidden City for long, but it dissipated after nearly a minute, as if it hadn't been there, leaving only the upgraded miniature intermediate Forbidden City.
