"War Commander Spirit, what kind of energy is used here?" Abel asked, looking at the circle in the center.

"Elder, the best circle here is, of course, to use gems full of energy!" replied the War Commander Spirit.

"Do you see if this quality gem is enough to replenish energy?" Abel asked, taking out a perfect ruby from the space bracelet.

"Of course, this is the perfect replenishment of energy, but such a gem is still too little for the entire base!" Although the War Commander Spirit was a little surprised when he saw the perfect ruby, he quickly thought about the reality of the base.

"Where do I put the gems to replenish my energy?" Abel asked casually.

"As long as it is placed in the central energy circle, the circle will automatically extract energy and supply it to the base!" said the war commander control engineering puppet, pointing to the central circle.

Abel kept throwing the perfect gem into the energy circle from the space bracelet, which made the white brilliance above the energy circle more and more abundant.

Ever since he knew that the energy used in the War Fortress was also a perfect gem, he had kept a large number of perfect-grade gems stored on his body as a backup.

Unexpectedly, at this time, these perfect gemstones came in handy.

He threw five thousand perfect gems into the energy circle before he stopped.

"Your Excellency, the energy of the base has returned to normal levels, all functions are being restored, and after inspection, the base needs to undergo a major overhaul before it can be put back into service!" said the War Commander in a cheerful voice.

It also didn't expect that the Elder's Excellency could provide so much energy at once, enough to keep the base running at full capacity for a hundred years.

"Let's go to the next floor!" Abel waved his hand, he wanted to see how much the entire base really had functions.

At this time, the benefits of abundant energy were immediately apparent, and a white light enveloped him and the engineering puppets around him, and they disappeared into the first floor, and then they appeared again on the second floor.

When he came to the second floor, he saw a huge space, where the sky was simulated by the magic circle, and there were no other buildings on the ground except for a few barracks.

"Your Excellency Elder, this is the training ground, and now it has enough energy, this training ground can simulate any terrain and terrain, so that the trainees can be tested in the most comprehensive and harsh environment in this place. War Commander Spirit introduced.

Abel couldn't help but be full of respect for the ancient race that designed this training ground, knowing that no matter what era it is, it is not easy to carry out comprehensive training in various environments, because to bring an army to various environments for training, regardless of whether the various forces allow it, it is a long way to go, and it is also an important reason why it cannot be carried out.

That's why the elves are good at jungle warfare, the dwarves are good at mountain warfare, and humans are good at city defense, and the orcs are good at plain attacks.

The training ground in front of us can make up for the shortcomings of the human army, so that the human army can adapt to all environments and greatly enhance its combat capability.

However, Abel will not be exposed in a short period of time, except for a small number of knights in the core of the family, it is not expected that outsiders will be able to enter here for training.

"War Commander Spirit, simulate the forest battle field!" Although the War Commander Spirit said the function here, Abel still wanted to see it with his own eyes, so he commanded.

"Yes, Elder!"

As soon as the voice of the war commander fell, white lines flashed on the ground of the training ground, which extended upwards and turned into white walls, dividing the entire training ground into countless small pieces.

In each small block, there were fluctuations in energy, and soon large trees appeared in small pieces.

When the white walls disappeared, Abel saw a forest, and with his eyes, he couldn't see any difference between it and the real forest.

Perhaps the only difference was that there was no life, and he couldn't help but step forward and touch one of the big trees with his hand.

The sense of touch told him that it was a physical object, but it did not have the vitality that trees should have, especially since his other class, the druid, had a clearer sense of the vitality of plants, and all trees were transformed using a strange magic circle.

"War Commander Spirit, how is this generated?" Abel said to the War Commander Spirit with a question.

"This is an energy creation, the result of research tens of thousands of years ago, but unfortunately it can only convert energy into the appearance of a physical object, but its internal properties cannot be converted, I only have information about this, I lost contact with the outside world with the seventh backup base ten thousand years ago, until you appeared here!" explained the War Commander Spirit.

"It's amazing!" Abel couldn't help but sigh as he looked at the energy creation in front of him that was no different from the big tree.

You must know that creation is already a means of the gods, and the ancient race has reached a high level at that time, and it can already create things with energy.

If the ancient races can be further studied, it is estimated that the energy creation will eventually be able to create items that are truly identical to the current items from the inside out.

It's a pity that the Ancient Race eventually disappeared into this world, and this technology is based on the War Commander Spirit, if there is no second base like this seventh backup base, which has maintained an energy supply for tens of thousands of years, then this base may be the last base left by the Ancient Race.

"The energy consumption of energy creation is not low, is it?" Abel asked again.

"Yes, energy creation consumes a lot of energy, but most of it can still be recovered, so the energy that was really consumed in this creation process just now only needs two gems that you provide. The war commander explained.

Abel doesn't care about the consumption of perfect gems, this perfect gem can't be circulated in the outside world, so he can only use it himself, even if he uses this base more, it just makes him spend more time when synthesizing.

When Able came to the third layer of the base, he found that this was the sea of bones, and the first time he entered the base, it was at the edge of this sea of bones.

"Your Excellency Elder, this is the training ground, and the combat power of the skeletons that appear can be adjusted according to the strength of the trialist, and this is the only place in the base where you can use dead qi to operate, so this is also the place where the base uses resource exchange to collect resources!"

Abel looked at this sea of bones, and knew in his heart that the ancient race was definitely not a good person, so many bones, how many living beings died.

But when it comes to those battlefield weapons, these are also normal, weapons like war fortresses, if all the accessories are complete, it is a killing tool, and the race that made these killing tools can imagine what their characteristics are.

In particular, this seventh backup base, the entire base, almost all of the base is used for war or logistics, and none of it is used for civilians.

"War Commander Spirit, why was I captured after I attacked that wall of air? Isn't this a training ground?" Abel couldn't help but ask when he thought of his own capture.

"Elder, since you didn't reveal your identity at the time, and the energy supply of the qi wall you attacked was not provided by death qi, as long as you consume the energy of the base, you will be considered an enemy!" said the War Commander Spirit explaining the reason.

Abel was a little speechless, how did he know that he would not be able to use the space items after coming in, and his elder identity card had been among the space items and could not be taken out.

He can also understand why as long as the energy of the base is consumed, he will be considered an enemy, thinking that the war commander has been saving the energy of the base for tens of thousands of years, and his own attack has consumed this energy that was not originally planned.

The result, of course, was to be seen as destroying the base and thrown into the garbage heap with no doors or windows.

After visiting the third floor of the base, Abel teleported to the first floor, where he was to stay for three days before returning to Nanmu Mountain to seize the portal's activator, and the entire base could not help him in the slightest.

Although the energy in the base has been restored, a large number of combat puppets have not been repaired, and countless magic circles need to be repaired, and the energy that has been decreasing for tens of thousands of years has caused great damage to the entire base.
