Let's go back to the moment when Red Archer shot and "exploded" Siegfried. At that time, Shinji was actually able to help Siegfried dodge the sudden arrow - others didn't know about Red Archer's existence, so how could Shinji not know? He had been waiting for this round of long-range attack.
There are two main reasons why he did not take action and allowed Siegfried to get hurt.
First, the "Dragon Blood Armor" is an immortal body that reduces damage. Even if it is broken, it will reduce the damage. That arrow was not aimed at the vital point and could not kill Siegfried.
The second and most important point is that Shinji has a chance to sneak attack Red Rider. And the best time is when Rider is gathering strength and preparing to kill Siegfried in one fell swoop.
Therefore, Shinji did not move, whether Siegfried and Red Rider were testing each other, Siegfried was shot and fell to the ground, or Fiore asked him questions, he just waited for the opportunity and asked for reinforcements to prevent Gold from causing trouble for him. If the fat man used a command spell to order Siegfried to use his treasure during the sneak attack, it would be a lot of fun. If things go wrong, the enemy will be safe and sound, but he will die under the sword of the friendly army.
Knowing that Fiore had dealt with Gold, Shinji no longer had to worry. When Rider was about to release his full-strength attack, he used his signature "Noble Phantasm Continuous Fire".
Indra's Thunder was in front, and I was holding Ishtar's spear behind, one on the head and the other behind, attacking Red Rider from both sides.
At the critical moment, Red Rider was shocked but not panicked. The moment the strange Servant's aura and magic fluctuations emerged, he gave up the target in front of him without hesitation. With one hand, he threw the spear with great power in the opposite direction to block the enemy Servant's attack and destroy the pincer attack; with the other hand, he switched weapons and used the shield to withstand the violent thunder. When Shinji bypassed the spear and charged again, Rider had already taken a defensive posture.
Even though Shinji used all his strength and activated the maximum power of "Magic Release", he only forced Rider back and knocked him away without causing any substantial damage.
If the lightning strike was not faster than the rider's speed in switching weapons, causing certain injuries before the shield appeared, this sneak attack would have completely failed.
Shinji didn't feel it was a pity that he didn't kill Rider or even injure him seriously. He knew the identity of Red Rider, a hero of the same level as Siegfried, and he was not that easy to deal with.
Of course, there is no fear. Since sneak attacks can't kill you, let's fight head-on. You are not the only one with backup, I have it too. If you don't run away, I will kill you today.
Therefore, facing Rider's aggressive provocation, Shinji responded with the same fierce attitude.
Red Rider looked at the wound on his shoulder and trembled all over, not out of shame, but out of joy.
"Great, that's great, you have someone who can hurt me."
The unrestrained rider vented his inner emotions with laughter. Just as he said just now, he was the kind of hero who laughed wantonly on the battlefield.
Another hero with a similar physique but opposite personality also recovered from the sneak attack. He casually pulled out the arrows from his body, silently raised his greatsword, and prepared to continue the battle.
"Two on two? That's not bad. Come on, Black Saber, Black Assassin."
"It's a two-on-two fight, but not in this way." Shinji moved sideways a few steps to block Siegfried, "Saber, I'll take care of Rider, you go deal with Archer."
Siegfried looked at Shinji questioningly.
Shinji glanced at the "eye" in the sky: "If I'm not mistaken, his immortal body can only be broken by the power of God. You took a defensive stance just now, and you instinctively sensed his restraint on you."
He said it was a guess, but in fact he was certain of it because he knew the real name of Red Rider. He just said that without wanting to arouse suspicion.
Saber nodded in agreement.
After seeing this scene and hearing Shinji's analysis conveyed by Fiore, a layer of cold sweat broke out on Gold's forehead.
The Command Seal was almost wasted, luckily Fiore was there.
"Uncle, I think you should trust Saber more." Fiore loosened her clenched hands and smiled with relief on her face, "Just like I trust Assassin."
Gold didn't say anything. He took out a handkerchief to wipe his sweat while recalling what he had done. Inexplicably, he thought of what the assassin once said.
"It is true that servants exist by relying on their masters, but they are not puppets. They have great power and their own will."
"To exert the greatest power, the master and the servant must reach a consensus. Otherwise, even the best-class Saber, the strongest hero, will not have a good ending."
Am I really wrong
Siegfried didn't know what the Master was thinking. Finding that he had no way to deal with Rider, he chose to trust his companions and go find another enemy.
Whispering "be careful" to Shinji, Siegfried rushed towards the direction where the arrow came from - he wanted to find the archer who was hiding somewhere.
"Don't even think about it—" There was no way that Crimson Rider would let Saber leave. He raised his shield and charged straight in.
Shinji inserted the spear in his hand into the ground. The power released by the spear shook the earth, tore the surface, and also blocked the steps of Red Rider.
"Your opponent is me!"
"Just an assassin?" Red Rider stared at Shinji fiercely, not hiding his murderous intent.
"Assassin is enough. Haven't you heard of the Killer Rider?" Shinji stared at the Red Rider without giving in.
"It's just one or two divine artifacts, don't be so arrogant!" The angry rider swung his javelin and launched an attack with a roar.
That style was completely different from the spearmen encountered so far. It didn't have the strangeness of Diarmuid, the dizzyingness of Garna, or the profoundness of Scathach.
Red Rider's gun skills are as simple and plain as his gun, without any tricks or disguises, and all his actions are just to kill the enemy - this is a gun skill that is truly honed for the battlefield.
This kind of gun technique may not look good, but it is practical enough.
Of course, there are also disadvantages. A gun technique that is only used for killing is destined to not be able to be both offensive and defensive like other gun techniques. As the price of pursuing lethality, its defense is relatively weak.
However, this weakness is not a problem for Red Rider, he has a shield, and a body stronger than most Heroic Spirits—not only immortality, but also the most basic physical qualities such as strength and endurance. In addition, he also has an unparalleled movement speed, even in the battle with Altria, Scathach, who was strengthened by the original rune, was weaker.
With the guarantee of speed and defense, Red Rider doesn't have to worry about defense at all. He just needs to attack, attack, and attack continuously.
This unrestrained style of play brought a greater sense of pressure than when facing Karna. In just a few rounds, the simple javelin had already grazed Shinji's vital points three times, each time closer and more fierce, and the most recent time almost cut Shinji's throat.
While continuously attacking, Red Rider also kept taunting.
"Hey, didn't you say you wanted to be my opponent? You're totally unqualified."
"Where's your momentum just now? Or are you just talking but can't do it?"
"Really? I've got my blood pumped up, but this is all you can do. Assassins should just stay in the dark. Why fight a direct battle? I'm so boring."
"Forget it, let's end it quickly. Although an assassin is at a disadvantage, it's not a complete failure."
As he said that, Red Rider put away his shield, held the javelin with both hands, and rushed towards Shinji like a meteor.
