Neng Jing has actually become the biggest factor hindering the guards.

It is precisely because of the hurdle of energy crystal that the wardens have been forced into a hibernation of zero-energy monitoring for millions of years. Because of this, it is impossible for these aliens to actively explore the Earth on a large scale to find their targets, and make the targets jump around so far.

According to Elusphinser's description, the Femira Shadow Regiment originally came to Earth on a pioneering mission, supervising workers and technicians to build a base and keep it functioning. Coupled with the powerful backing up of the space-time gate, these imperial elites traveled lightly and only carried the standard number of ninth- and tenth-class energy crystals.

The devil knows that the base was destroyed by an explosion, and the on-duty guard work like a leisure vacation became a distant guard mission in the blink of an eye, and it was a million years to do it.

It's okay that the space-time gate attachment was destroyed, but the worst thing is that no one expected things to turn out like this, so they ignored one of the most critical devices: the energy crystal collection synthesizer!

This is a very large and complex set of equipment, including a multi-source energy extraction synthesis device, as well as an expensive and rare energy crystal fester.

The consequences of surviving in an unknown territory without any backup can be catastrophic, unless you return to primitive life, which is indeed what the Wardens have done on Earth for more than a million years.

Energy crystal is the foundation of the survival of the cosmic civilization system, the blood of this behemoth, and the hard currency that is more scarce than money and materials.

In the universe, according to the division of the scientific and technological authority: the intelligent race, the energy crystal is divided into ten levels from low to high.

The lowest class of ten energy crystals, one unit contains one special energy, that is, one billion kilojoules of energy in the concept of the earth, and the market circulation price is ten star coins. This price will also fluctuate according to many factors, only high and not low.

And the higher-level nine types of energy crystals, under the same unit system, the energy reserve is one million times that of the ten types of energy crystals!

This multiplier difference is strictly defined by the Zhi clan and unconditionally implemented by all parties in the universe. From the tenth to the fourth category, these seven energy crystals are produced and manufactured according to such standard specifications, and circulate in every corner of the universe with civilizations.

No matter how big or small, strong or weak, the highest-level energy crystals that can be produced by themselves can only reach the fourth category. Because the first three energy crystals can only be produced by the Zhi clan. And this is also one of the factors of the transcendence of the Wisdom Race.

Don't look at the fact that Nengjing is divided into only ten levels, but the level of integrated technology contained in it is unimaginable.

You must know that the capacity of each type of energy crystal is a million times different, but their shape and volume are the same standard, and they have to be cut and packaged into countless strange shapes with special instruments as needed to meet different kinds of energy slots.

A pistol may have exactly the same energy slot as a ship's main gun, but the type of energy crystal they require is four or five levels different. The list goes on and on, so it is necessary to have a very strict measurement system with a sufficient energy supply.

Normally, in the daily needs of all parties in the universe, only the eighth, ninth, and tenth types of energy crystals are sufficient, not to mention how economical, at least they can afford it. Only when performing super-intensive energy consumption activities for a short period of time can the seventh to fourth energy crystals be used painfully, such as annihilation-level interstellar warfare.

And the highest-level third-to-first-class energy crystals belong to the patent of the Zhi clan, and only the master, or a fourth-order powerhouse with a rich family background, can touch it, and others still have to think about it.

Moreover, between the various categories of energy crystals, not only the efficacy is very different, but also the manufacturing process and cost are very different, not to mention the price, the difference can not be calculated. Compare the worst ten types of energy crystals with nine types of energy crystals, and convert them into circulating currency, which is a difference of more than a million times.

Therefore, for the general public in the advanced civilization areas of the universe, in addition to the local tyrants and impatience, nine out of ten are using the tenth type of energy crystal, and the tenth type of energy crystal is also affectionately known as the master key.

Unfortunately, nothing is perfect. Energy crystal, the food that the whole universe depends on for survival, is like the earth's battery, and the energy it collects will slowly escape, otherwise it violates the cosmic iron rule of conservation of all things.

Moreover, the lower the grade of the energy crystal, the faster the escape rate, because the reason why the high-grade energy crystal can store such a huge amount of energy is that its packaging technology is naturally unique, which involves scientific and technological secrets and cost issues.

According to Elus Finser, an empire of Atlantis' size can only produce its own energy crystals of the eighth, ninth, and tenth grades, and all the higher-level energy crystals rely on imports.

What's even more coincidental is that the two types of energy crystals held by the Warden, although the ten types of energy crystals are known as the master key, their shelf life is only about 10,000 years, and the shelf life of the nine types of energy crystals is exactly about one million years.

In other words, to this day, all the energy crystals carried by the Warden have just expired. Even if some of the nine types of energy crystals are tenacious and have not expired, they are already on the verge of the alarm value.

This can't help but talk about the luck of the God Butcher Troupe, it's really good!

Therefore, due to all these factors, the Guardian is running out of ammunition and food, and is all dependent on his tenacious will as an evolutionary being. Most of those high-tech weapons and equipment are scrapped, because they must use the precious energy crystal resources for the normal operation of the most critical combat uniforms and communication detection equipment, and as for the weapons, they are not much different from scrap metal.

There is also a very important piece of information in the bracers, that is, when the Femira Shadow Regiment came to Earth, it had a spaceship, codenamed "Firefly".

The data shows that this is an interstellar research ship, similar in function to the "Shaking Light", with simple defensive weapons, without the ability to sail faster than light, and the conventional maneuvering ability is far inferior to the "Shaking Light", and the maximum speed is not as good as the minimum cruising speed of the "Shaking Light".

The "Firefly" is saucer-shaped, with a diameter of 187 meters, the thickest hull, and carries four sub-aircraft. The sub-aircraft is also a saucer-shaped, with a diameter of only 4 meters and a thickest part of 5 meters.

The "Firefly" spaceship has not been seen since the explosion and destruction of the temple, and its whereabouts are unknown. However, Femira has long claimed the four sub-aircraft, and uses their high intelligence and unmanned convenience to fly around the world from time to time, which is an important means for the watchman to monitor the world. A large part of the UFO traces occasionally found by humans on Earth in recent centuries are due to these four small things.

Aside from the above-mentioned hardware, the Warden has no more money.

As for the evolution potion, enhancement potion, all kinds of bits and pieces, they were all personal belongings of the Warden members, and Elusphinse didn't know the details about it.

For example, the antimatter element 74 that she occasionally found in her prison position: the Egyptian Oasis of Death, in line with the tradition of first-come, first-served among wanderers, naturally became the bag of Elusphinser, and no matter how greedy the others were, they could not snatch it by force, and could only make an equivalent exchange request.

The above is a general equipment situation for the Warden.

Now there's the main event: the personal strength of the Warden members!

Everyone in the God Butcher Group knew how significant this thing was, so the scene was silent, and they all held their breath and watched carefully, for fear of missing a single detail.
