"Oh, this is the power of the spell, it's amazing." Caesar looked curiously at the pattern on the back of Xiao Shirou's hand.

The Spell, a very magical mark in the Holy Grail War, is the ticket to participate in the Holy Grail War, and it is also the limiter for the Master to control the Servant Heroic Spirits.

There are three spells, and the Master can consume a spell seal to use an Absolute Command, and when the Spell is used, the Heroic Spirit will unconditionally obey the Master's orders, even if it is an order to kill the Heroic Spirit itself.

In addition to giving absolute orders that the Heroic Spirit cannot resist, you can also use the powerful energy of the Command Spell to increase the power of the Heroic Spirit and have a strengthened effect.

Although there are three spells, however, ordinary magicians will only consume two, leaving one just in case, if you encounter a heroic spirit servant who is too angry, if you are eaten by it, it will be very bad.

Xiao Shirou was just a child, and he was not a magician, so he didn't know the preciousness of the spell at all, and he used one of the three precious spells unconsciously to use it.

And the power of the spell is indeed powerful and weird, and Caesar was unprepared for it, and he was also affected.

However, because Koshirou's spell order was to restore his parents to normal, the illusion was interrupted, and the Kudo couple woke up, indicating that the order of the spell had been completed, and the binding power of the spell disappeared.

“！！” In Fuyuki City, some people with keen senses all frowned, and no matter what they were doing, they all stopped.

"What's wrong?" The person on the side asked.

"Hmph, there is a miscellaneous person peeping at this king, hiding quickly, if you let this king catch, you must let him know what the price will be if you dare to peep at the king." The golden-covered Wang said arrogantly.

"Hahaha, there seem to be some interesting people." The burly and heroic king laughed.

"Master, we may have been exposed...", the girl king in the suit reminded.

"Woo-oh-oh!" The knight, whose body was wrapped in black qi, let out an irrational roar.

"......" is an assassin with a skull mask and a whole body hidden in the dark, without any indication.

"Master, looks like you're feeling it too." In the presidential suite of the most luxurious hotel in Fuyuki City, a handsome knight with two guns said.

"Of course, although it is very weak, but such a reckless passage through my magic position, is it to underestimate me, or not to take the people who participated in the Holy Grail War in their eyes, so arrogant, it should also be a Heroic Soul Servant." The genius magician stands in front of the floor-to-ceiling windows, looking down on the city.

"It's almost there, the spell... The Fourth Holy Grail War... It's kind of interesting..."In the house, Caesar opened his eyes and smiled playfully.

"Next...", Caesar looked at the frightened Kudo couple, and the little Shirou who was held in their arms.

A few days have passed in a blink of an eye, and Caesar has already lived in Kudo's house, and Kudo and his wife have left the city to travel abroad for a vacation, and there are only Caesar and Koshirou in the huge family.

Caesar vaguely remembered that the outcome of the Fourth Holy Grail War did not seem to be optimistic, and Xiao Shirou should be the future Emiya Shirou, that is, the future Heroic Spirit Red A.

And Caesar also guessed why he was summoned to this world to become the heroic spirit of Xiao Shirou, which should still be the reason for the mutated psychic contract.

In the Land of Eternity, Caesar signed a psychic contract with the doppelgangers of Daddy Whitebeard, Zoro, Orochimaru, Kakashi, Sasuke, and Red A.

Through the mutated psychic contract, Caesar and their essence have a subtle connection, and when their essence produces strong emotional and mental fluctuations, Caesar will be pulled to that impossible space, and the two sides will meet each other.

Caesar would be drawn and summoned into their world.

Caesar was pulled by the mutated psychic contract, summoned by Xiao Shirou, and came to this world, and as a result, he became one of the seven servants by mistake.

Because Shirou is still young, he hasn't experienced much mood swings, unlike Whitebeard's dad who faces life choices, Zoro's childhood friend died unexpectedly, Kakashi's father committed suicide, and so on.

Therefore, Caesar has never seen Shirou in that indescribable space until now.

However, if Caesar hadn't entered the magic circle this time, and the Fourth Holy Grail War had been going on normally according to the trajectory of history, after the Fourth Holy Grail War ended, Fuyuki City was hit hard, Shirou's parents died, and Caesar might have met Shirou in that indescribable space.

But now, Xiao Shirou doesn't know why, maybe because of the reason related to Caesar's psychic contract, he was chosen by the Holy Grail to become the host Master, summoning Caesar to this world, and the trajectory of fate has begun to change.

The Holy Grail War, seven Heroic Servants, divided into seven classes, namely Saber, Lancer, Archer, Rider, Caster, Assassin and Berserker.

Seven ranks are not allowed to be repeated, and each Heroic Spirit who participates in the Holy Grail War is a different rank, and according to the nature of each Heroic Spirit, as well as the magician master who summons the Heroic Spirit, etc., it is determined that the Heroic Spirit is suitable for that rank.

Many Heroic Spirits can adapt to a variety of classes, but one thing is that after one class, the power of one class will increase, while others will decrease.

For example, the condition to become a knight of the sword is a hero who uses the sword as a weapon; The condition of the knight of the spear is that he is a hero who uses a gun as a weapon; The condition of the knight of the bow is that he is a hero who uses a bow and arrow as a weapon; The condition for a mounted soldier is that it is a hero who has a relationship with the mount.

Among the legendary heroes who can leave a famous name in history, which one is not proficient in swords, guns, swords, halberds, and riding mastery is the foundation of the foundation.

Take the famous Three Kingdoms hero Zhao Yun as an example, everyone knows that Zhao Zilong, a white horse and silver spear, is holding a gentian bright silver spear, which directly meets the conditions of the knight of the gun.

In the seven in and seven out, Zhao Yun killed Xia Houen to seize the Qingyu Sword, and the seven in and seven out of one shot and one sword also met the conditions of the knight of the sword.

Moreover, for the general, the bow and horse need to be skilled, Zhao Yun's archery skills are also very good, but he is not as famous as the gun in his hand, just like Huang Zhong is famous for arrows, few people notice that Huang Zhong's big knife is also a tiger and a tiger, so Zhao Yun is also in line with the rank of the knight of the arrow.

Sword, gun, arrow, horseman, Zhao Yun is suitable for all four ranks, but he can't do them all, he can only choose one of the professions, for example, after becoming a knight of the gun, the spear skills will be strengthened, but in other aspects, the appropriateness will be reduced.
