"Spells like fainting, removing your weapons, and obstacles can all be defended against with armor...... Joel gave the students a lecture on stage, and Harry raised his hand.

"But as far as I know, the magic required for the Armor Charm is quite amazing," Harry said, standing up and asking his own question, "If I cast the Iron Charm at will, will it affect the state of my mana?" ”

Joel nodded, "Harry, your point of view is not new, many wizards have raised this issue before, and the Iron Charm is wasteful in many cases. ”

"For example, the mana index consumed by the opponent to cast a stun spell is 10, and you can't know exactly how much mana the opponent consumes, you can only consume 15 index of mana to build an iron armor spell, of course, the spell can block the attack, but the difference between the 5 points of mana is considered to be lost in vain."

"But I have to say that this is a very common drawback," Joel continued, "just as the Dark Arts trade a lower magic price for a stronger spell, it is unrealistic to fight against a Dark Wizard, and with the same magic base, the wizard who uses the Dark Arts retains a better state of magic, and the best way to deal with them is to fight quickly and not give them a chance to breathe." ”

Harry sat down as if he didn't understand.

"Next, let's practice the Iron Armor Charm one-on-one." With a wave of his wand, Joel pushed the desks and chairs in the classroom around, leaving a large open space in between.

Ten people work in pairs, and under Joel's arrangement, one side uses the Petrification Charm to attack, and the other side uses the Iron Armor Charm to defend.

Harry and Ron made a pair, and it has to be said that Harry's talent in duel spells is really top-notch, and it didn't take long for him to master the casting essentials of the Iron Armor Spell, blocking Ron's attacks.

A night of training and Harry's private practice allowed him to improve his dueling skills by leaps and bounds, and these improvements were directly reflected in the Dueling Club event in October, when Harry managed to crush his peers with an Iron Charm and defeat Crabbe in Slytherin.

Seeing that Draco Malfoy, who claimed to have injured his arm and couldn't play, had nowhere to vent his hatred on his face, Harry was in a good mood and wanted to jump three feet high and thank Joel.

At this time, the person Harry wanted to thank was lying on his back on the bed in the dormitory, the quilt was tightly covered, his eyes were closed, and he walked peacefully.

Joel now re-enters the World Tree, taking Odin's identity and trying to survive Ragnarok.

As soon as he completed his identity replacement, Joel felt that the world was shaking violently, making people unstable on their feet, as if an earthquake was hitting the ground.

Joel opened his eyes and saw a frightened Frigga beside him.

"What's going on?"

The woman's face was full of worry.

Joel walked out of the palace with his cloak on, and the sky was dark and unbright, dead silent.

The surrounding guards also rushed over at this time, and Joel could still hear the neighing of horses in the distance, and Asgard was already in disarray.

"Don't panic," Joel said as he took Gongunir from Friga behind him, intending to go to the backyard to pick up Slepnis, "you take care of Frigga. ”

The guards nodded in agreement, as the guards of the Aesir Protoss, they also knew some rudimentary spells, and their strength was much stronger than that of ordinary humans.

"Be careful...... Frigga admonished, frowning.

This war is a matter of life and death, and Joel has no heart to comfort Frigga at this time.

Riding the eight-legged horse Slepnis, Joel gave the order, "Let the Valkyrie Maiden come to me with the Heroic Spirit." ”

The guards ran to report the news, and Joel looked at the rainbow bridge in the distance and sighed.

Urging the horses forward, the earthquake continued, and Joel knew that the poisonous dragon Nidhogg had gnawed off the roots of the tree, the World Tree had begun to crumble, and the end of the gods had come.

He led his servants to the end of the Rainbow Bridge and made it to the atrium, where the ground finally stopped shaking, but the ground cracked, revealing the endless abyss below, and the atrium was already in ruins.

Three years had passed since the sun had last risen, and most of the creatures left in the human kingdom had shrunk into corners, and the half-hour-long earthquake had caused countless buildings and trees to collapse, destroying their remaining shelters.

Many people died directly in this powerful earthquake, and the rest had to face the starving beasts besieging from all sides, and there was no doubt that it would be another human tragedy.

Joel on the horse didn't have time to think so much, he hurried forward, Thor and the other gods were still in Asgard at the moment, and they would come soon, he couldn't sit still in the decisive battle of fate, if he wanted to survive the twilight of the gods, he had to strike first and break the armies of all directions.

Separated by a bottomless chasm between Muspelheim, the land of fire, and Niflheim, the land of fog, is the land of the fire giants, whose leader is Surtr, who is also the enemy of the gods of Asgard and the archenemy of Odin.

After the sun disappeared, Surtr knew that his chance for revenge was imminent, and he recharged for three years to cut off Odin's head with his own hands!

Now he set off from Musberheim with a group of Fire Giants and headed straight for the Rainbow Bridge, but he didn't expect to meet the Heroic Spirit army led by Joel halfway through.

"Odin?" Surtr looked at the man on the horse in the distance, and he became serious and cold.

He didn't expect to meet Odin in this area, in Surtr's vision, Odin should be cowering in the wide Valhalla at this time, how could he run to the human empire in the atrium?

In response to him, a spear broke through the air, and Gunnir appeared in front of Syltel in the blink of an eye with infinite momentum.

Surtr knew that this spear could not be dodged, so he could only resist it, but he was not stupid, and grabbed a fire giant servant beside him and stopped him in front of him, carrying the sharpest attack of Gangunir for him.

The spear pierced through the fire giant's thick chest without any suspense, and then plunged into Surtr's shoulder, leaving a bowl-thick hole in the fire giant's leader's shoulder, and the spear returned to Joel's hand.

Surtr threw the corpse of the fire giant in his hand, looking at the wound on his shoulder, he felt hatred and anger in his heart, but he couldn't do anything about Joel.

The weapon he possessed was a giant sword of fire, and its melee attacks were immensely powerful, making them useless against Odin's ranged weapons.

Surtr ordered the fire giants behind him to rush forward, and only by shortening the distance between him and Odin could the Fire Demon Sword be useful.
