As the defensive battle continued, two hours had passed.

With the counterattack of the rune array in the stronghold and the cooperation of Delphi outside the stronghold, a large number of corpses have gradually accumulated outside the magic barrier emitting a faint silver glow.

However, this time, the army of corpses is not only a large number, but also becomes quite difficult under the control of "arrogance". It can be said that judging from the current situation of the war, perhaps the battle has just begun.

However, of course, these corpses are not tired, but Delphi, Harry and brova will always be tired if they continue to fight hard outside.

Harry, in particular, is only good at melee compared with the other two. As long as he holds the Gryffindor sword in his hand, his combat effectiveness will not be weaker than that of Mr. blova.

But this time, he was really at a loss in the face of a large number of enemies who would almost certainly choose to explode before losing their combat ability.

Even if he could go out and risk the real power of Gryffindor's sword like when dealing with giant demons last time, he could not kill all the corpses in a short time. What's more, behind these corpses, there is a demon peeping at everyone.

Harry knew very well that the defensive battle would not end in a moment and a half.

So Harry fought very hard and was the most tired of the three at the moment.

"Hiss -"

When the bright blade flashed across the neck of a living corpse, Harry, who tilted and half hung on the fire crossbow, immediately pulled his body back to the broom, and immediately pulled up the broom handle and raised it dozens of feet.

The next moment, I heard a "bang" below, accompanied by the impact of the air flow and a very uncomfortable cold feeling.

He didn't have to look back, because he knew that there must be a black flame rising at the moment - this thing that looks not much different from Safina's black flame is obviously different from ordinary flame, with a chill that seems to touch the soul.

You can feel this without actual contact. It's conceivable that it's not fun if you're really burned.

"Hoo... Hoo..."

After controlling the broom to fly parallel to the ground again, harriton gasped when he just made a breath holding dive. No way. Although he had an unusual talent in Quidditch, he was fighting now. After nearly two hours of uninterrupted fighting, he was already very tired.

But

"Kerala -"

Accompanied by another pure white cold, it quickly floated down from the air and landed in a large group of living corpses not far away. In an instant, the actions of those living corpses became slow and even completely frozen into ice sculptures. As soon as Harry saw it, he was not satisfied with Delphi's strength.

Therefore, even if he was really tired, he still had to choose to continue fighting - at least not to drag down the other two.

So when he saw Mr. brova on the other side controlling a flame flying dragon to spit out flames, he immediately dived down again.

Even in his current fighting style, one sword can cut down at most two or three corpses. But at least the enemy kills one less. As long as each less corpse rushes to the protective barrier, it can reduce the pressure on the protective barrier of the stronghold.

But just then, Harry suddenly felt a chaotic air flow suddenly pressing down on his head. He looked up quickly, but it was Delphi driving her ice giant bird flying towards him.

Seeing this, Harry quickly said goodbye to the broomstick handle, crossed a reverse arc in mid air, and wound around Delphi standing on the back of the ice bird.

"What's up?"

Although the weariness in his eyes could not be concealed, he still held his sword upside down and asked firmly.

"It has been nearly two hours. Just now Miss Granger gave us a sign. We can leave the battlefield here and have a rest first - Miss Geoffrey and Mr. Longbottom have joined the counterattack of the stronghold."

"Have they rested?"

Harry looked back, and sure enough, he saw a figure shrouded in black flames flying up on the platform at the top of the East Tower. Although he didn't come out of the barrier, he had begun to spill a lot of soul flames towards the outside.

Because the rune array designed by Hermione can not be controlled very finely like Sarah's Alchemy barrier, once started, people must be unable to get in and out.

However, fortunately, the magic spell inside can penetrate without obstacles, which is one of its advantages compared with the alchemy barrier.

It can be seen that the counterattack in the stronghold is still going on, and the roar of the explosion curse is still continuous, making a sound.

"But..." after seeing the picture, he turned back and looked at Delphi, "but you and Mr. brova seem to have spare strength. Why don't you stick to it for a while! Hermione said before that the second barrier will last as long as possible - there are too many enemies!"

However, Delphi just stared at his face and shook his head.

"I can go on, and Mr. brova should have no problem - Summoning is more suitable for such a long-term battle. But Mr. Potter, you need to rest."

"I have no problem!" Harry said loudly, raising his sword in his right hand. "Don't worry, I'm not tired."

However, his fatigue could not hide from Delphi's eyes. As soon as he finished, he saw the latter shaking his head again.

"Mr. Potter, you have to understand what your value in this battle is," Delphi reminded calmly, "The devil hidden in the dark may appear at any time, and your main task is to retain your energy, block it at that time, and defeat it as much as possible with the cooperation of Mr. brova and I! Neither he nor I can hurt the devil as well as your sword, okay - think about the 'big guy' before."

Although Harry wanted to kill more enemies, he had to admit that Delphi was obviously right. After being persuaded by the other party, he had to sweep the handle of the broom and turn around to the west of the stronghold after another look at the living corpses below.

They can't get in the stronghold for the time being. Seeing that the number of living corpses there is the least, they should be able to find a place to rest for a while.

At the same time, buluowa saw that they were going to leave and immediately caught up with them - he only left his flame flying dragon here.
