"You really should be prepared for soundproofing first. 」

At this time, Alan was sitting on the ground, shaking his head constantly, far beyond Allen's expectation of a huge explosion that shook Allen's dizziness, and he could no longer hear any other sound in his ears except for the roaring buzzing sound, although he tried hard to stand firmly, but his hands and feet were completely uncontrollable, how to walk were crooked, and finally had to give up sitting on the ground and wait for his body to recover naturally.

"Ahh

"Big Lump of Meat...... Has it been wiped out?Was it made by Talon?Or was that thing just destroyed by Canon?" Alan observed the situation below a little, the druids had all been released from the beast state at the moment, and were sitting on the side to rest, Talon seemed to see Alan's figure, and was waving happily at Alan, Guna was crying and saying something to Claw, and the claws were in a hurry. After the large piece of meat was eliminated, the elves were finally able to concentrate on blocking the necromancy, and it seemed that there was no danger for the time being.

Alan smiled and waved his hand at the claw, then went straight to check on Ganon's condition. Originally, Allen's plan was to launch the spiral rock projectile, and immediately go with Talon to destroy the big piece of meat that was hit hard, but he didn't expect that he couldn't go down immediately to support because of the impact of the explosion. The battle is over.

The black cylinder is dark red because of the great heat energy, and the light distortion caused by the high temperature can be faintly seen around the barrel, and the earthen pedestal under the barrel is close to shattering at this moment, if it is not specially made This pedestal, I am afraid that the entire barrel will be affected by the reaction and buried in the soil.

"I can't help it, after all, it's just a temporary product of the accumulation of ideas, and it's good to achieve the goal. Alan sighed lightly, this cannon was the product of accumulating ideas while making Roland and Lilith's weapons, the finished product was extremely rough, only considering the goal of achievement, but it could not be used as a stable means, at least when Roland's team was fighting the necromantic creatures, Alan couldn't find the space to set up this cannon at all, even if he held it in his hand and fired it, most of the time he would only be seriously injured by the reaction force, let alone shoot the big piece of meat.

In fact, it is quite simple to make a cannon, but to make a powerful cannon, you have to face a lot of problems, the most important is accuracy, reaction force and barrel strength, the evolution of the cannon is basically inseparable from these three things, as long as these three problems can be overcome, then as long as the fuel as propulsion is enough, the power of the cannon can be almost infinitely improved.

At this point, hydrogen fuel has more advantages than solid fuel, because whether it is hydrogen or methane, the combustion efficiency is extremely high, far from what black powder can compare, as long as an instant, hydrogen can complete the combustion, powerful energy and expanding gas can easily turn any solid object into an efficient killing weapon.

"I think so, but the actual results are a bit disastrous. Alan muttered to himself as he looked at the barrel that had cooled down.

"Kah. There was a crisp metal crack, and then, like a chain reaction, several metal cracks came from the barrel, and then spider web-like cracks began to appear on the barrel, and it seemed that the barrel had completely reached its limit, and it was not to the extent that it could be used after repair.

"Ugh. Alan sighed again, and at the same time glad that he had added strong and stable runes to the writing technique, but after the input magic energy disappeared, the damage to the cannon body was still clearly reflected, if there was no reinforcement of the rune technique, I am afraid that the cannon barrel would be directly blown into pieces at the moment of explosion.

Alan reflected on his recklessness a little, and then quickly put all the pieces into the space ring as a reference for future improvements, and then strode directly towards the valley.

"I don't know if Alevia is okay, but I only saw that nasty guy, but I didn't see Ainevia. Alan walked towards the valley, thinking about Ainevia, and at the same time, the necromantic creatures outside the valley also noticed Alan, in their eyes, this was a fresh food that was generously moving towards them, and some of the necromantic creatures couldn't stand it anymore and pounced on Eren restlessly.

......

"What kind of means is that?Druid's weapon?or is it the magic of Goddess Freya?" Elo felt that his brain was in chaos, the large piece of meat that they had been fighting hard for so long was actually solved by a strange stone?And if he was right, that stone should have directly hit the necromantic core in the body of the large piece of flesh, that is, the black crystal that all necromantic creatures will have, and without the supply of necromantic energy, the large piece of meat would naturally die. Being able to strike with such precision from such a distance made Eloul feel a deep sense of fear. He couldn't help but think, if that thing shot at him, would he be able to dodge?

"No, I can't hold it in front, Young Master Ailuer!" An elven marksman walked up to Ailuer's side and said, seeing that Ailuer's expression was a little dazed, he quickly reached out and touched Ailuer's shoulder.

「...... What's wrong?" replied Eloul as she came back to her senses.

"The elven mages have reached their limit, can we ask the druids to help us block those necromancy, so that the elven mages can rest?" said the elven marksman anxiously.

「...... No, they've just finished performing their frenzy, and now is the weakest time, and the druids who can't even use the beast won't have much combat power. Elo sighed and said, he couldn't help but feel a sense of powerlessness, obviously the druids desperately solved that big piece of meat, but their side couldn't stop it?

......

"Everyone's eyes closed!"

"......?" the elves looked at each other with some confusion when they heard the unfamiliar voice, as if to confirm who had given the order. On the contrary, the druids closed their eyes at the same time under the command of the claws, and a few druids were worried that they would not close it tightly, so they even covered their eyes with their hands.

Almost at the same time, a burst of intense white light emanated from directly above the gathering of the undead, almost as if the sun had fallen directly on the heads of the undead.

"Ahh

"When did even the necromancer manipulate the light? impossible, and how does the voice that told us close our eyes sound familiar?" Eloul blinked his eyes to see the target of the attack, but he could only vaguely see a figure walking towards them.

"Huh?" Eroll felt like something was wrong, just a figure, nothing else?

"The necromantic creatures have been wiped out!" a spirit who had narrowly closed his eyes whispered to his companion in the valley, his voice full of surprise and deep exhaustion of relief.

At this moment, on the flat ground outside the valley, a black-haired teenager was slowly walking towards the valley with a smile, and the originally dense necromantic creatures had all disappeared at this moment, and countless black crystals could be vaguely seen on the ground falling to the ground.

Suddenly, the boy stopped, and saw him mumble a few words about what he knew and do more, so that he didn't know if it was enough, and touched his chest, as if to confirm something.

"Who are you!" one of the elves didn't react until now, and said aloud to the black-haired boy.

"Hello everyone, I heard you need help?"
