Under the systematic assessment, the upgraded Spartan Praetorian Guard is nearly twice as effective as the elite of Wei Wushu, obviously, the Spartan Praetorian Guard is not as simple as adding a set of heavy armor compared to the original Spartan trouser man!

This is the hegemony of the all-out war system, basically as long as the 'resources' are sufficient, and do not exceed some kind of limit that Lei Zihao cannot understand, this all-out war system can continuously improve the physical fitness of the soldiers, or the kind in batches!

Since crossing over to this world, Lei Zihao has roughly figured out what the 'resources' required for the all-out war system are!

Whether it is the power of war belief or the currency attached to the spiritual power of the world's indigenous equivalents, it is all related to the mysterious soul power of intelligent creatures, and it is not difficult to see that the reason why the all-out war system can materialize the army and civilians out of thin air is inseparable from the spiritual power derivatives of intelligent creatures in this world!

Perhaps, in the dark, the system of total warfare also follows some incomprehensible law of conservation of matter. Pen ~ fun ~ pavilion www.biquge.info

In addition to the soul power that cannot be seen and touched, the power of the dead flesh of the creatures in this world seems to be able to be captured by the all-out war system, which is the so-called killing experience extracted from the essence of life!

It's just that in the eyes of Lei Zihao, the purification rate of this 'resource' seems to be too high, if you want to extract a drop of qi and blood essence that can promote ordinary people to trainee knights, you must at least kill hundreds or thousands of times more trainee knights, and there is no condition for batch manufacturing masters, at most, it will benefit Lei Zihao himself, enhance his physical fitness, and prolong his life.

And there is also an unsolvable sequelae of not being able to have offspring!

However, that gladiatorial arena seems to be able to make more efficient use of the life essence collected by living creatures when they die, and the gladiatorial arena that the total war system says that the gladiatorial arena cultivates warriors by consuming the lives of slaves, which is actually a disguised process of gathering the life essence of a large number of ordinary creatures, that is, the killing experience into one creature!

It's a cruel act, but for Lei Zihao, it's all good and harmless!

The number of slaves in Longhan City is now close to the 100,000 mark, and the labor gap has already overflowed, if they are all used for slaughter and exchange for killing experience, Lei Zihao feels that the efficiency is too low, not to mention, the current Longhan City is extremely short of funds, and even the regular troops can't be recruited!

From this point of view, it seems that the gladiatorial arena does not cost gold, and the way to train slave warriors is also very good!

After experiencing the defensive battle of Megala, Lei Zihao naturally opened the small gladiatorial arena to speed up the construction mode, and after the war, Lei Zihao's army was greatly damaged, if it were not for the prestige of defeating the Crusaders and the deterrent power of the re-replenished and upgraded Scarlet Crusaders and Spartan Janissaries, the large number of slaves would have rioted!

Lei Zihao urgently needs to convert slaves into a small gladiatorial arena that can be used as soldiers, even if it only produces slave gladiators equivalent to the combat power of trainee knights and champion gladiators equivalent to the combat power of regular knights, it is good!

As for the high cost of slaves, it was ignored by Lei Zihao, even if a hundred slaves were exchanged for a slave gladiator, Lei Zihao would admit it!

There are a hundred slave units here, not all kinds of slaves meet the requirements, they must be soldiers who are physically strong and have experience in the army, preferably veteran-level slaves!

Otherwise, we will have to rely on quantity to make up for the quality gap......

In the human world, the battlefield role of a trainee knight is equivalent to 10 ordinary soldiers at most, and even sometimes it is not as good as a cluster of array soldiers!

However, it takes a hundred slaves who have undergone rigorous training to serve as soldiers of the noble standing army, and it is possible to train a slave gladiator who is only equivalent to the combat power of a trainee knight!

That's at least 10 times the extra loss!

In Lei Zihao's eyes, this is completely inconsistent with the law of conservation of 'combat effectiveness'......

But this is also a helpless thing, to be able to achieve this kind of extremely costly slave conversion is already the limit of the all-out war system, if the noble lords know that Lei Zihao has such a bug-like building, I don't know how to be jealous!

After all, no matter how many hostile soldiers and prisoners of war there are, they are not as useful as a soldier who is loyal to them, right?!

Loyalty, for rulers, is often more important than combat effectiveness!

It's just that so many slaves who have participated in the battle, if all of them are invested in the gladiatorial arena for a large amount of 'loss' consumption, Lei Zihao feels that it is still a little unworthy, so he asked Li Si, a 'professional counterpart', to select prisoners who are willing to be loyal to him from the crusader prisoners of war, and re-form cheap and useful cannon fodder soldiers!

In the battle against the Crusaders, the Cyris in Megara City had been too strong to be damaged in this war of attrition in Meghala City, and it was no longer possible to pull out a Seris Revival Army......

According to incomplete statistics after the war, from the beginning of the defense of Megara City, more than 10,000 people died in Seris, including the soldiers!

Many of the Cyris civilians were residents of the city of Meghala who had been smashed into meat sauce by boulders that fell from the sky and smashed them along with their houses......

The Seris nation now regards Lei Zihao as their king, and Lei Zihao naturally can't transfer the small number of young and strong people of the Seris nation, if all the men in Seris are dead, will he still have to find a partner for a group of Seris widows?

Therefore, it is a must to select cannon fodder soldiers who are willing to serve from the prisoners of war!

There was no patriotism and nationalism in this era, and the soldiers at the bottom had little allegiance to the noble lords who were high, and the basis for the noble lords to maintain their rule was not these mud legs and mercenaries who worked for money, but the knightly class who had common interests and valued their honor and status!

It's a knight with real combat power, not a noble knight in the history of the earth!

Therefore, recruiting prisoners of war who know the times, even in the aristocratic civil war in the human world, is a very common behavior, of course, there is no need to count on the temperament of the renegades in these prisoners of war, let them do miscellaneous work and serve as cannon fodder, and they must not be allowed to act as the main force of battle!

Li Si, a general, is very mediocre in other aspects, but this eyesight is very comparable, as long as the prisoners of war he selected are adjusted, the combat effectiveness may not be improved too much, but the probability of defection can basically be eliminated!
