This was the last thought of Crent's life.

"Oh!"

Long live the Lord! Long live the Lord of the City!"

"Long live Cartel City, haha, brutes, you can't get in, you just can't get in!"

When they saw the demon beast waving its claws and tearing it towards the giant net, everyone's hearts couldn't help but tighten, and their eyes stared at the monster and the giant net motionlessly. In the next second, just when the demon beast was about to rush to the giant net, several strong lights suddenly lit up on the giant net, and the light that was originally the thickness of the arm turned into the thickness of a wooden stake in an instant, and the dazzling light points jumped on the light, even if they were far away, people could still feel the power of the light. In the exclamation of everyone, the demon beast that suddenly turned back didn't have time to react, and hit the giant net heavily.

And then......

Looking at the corpses of the demon beasts sprinkled all over the sky, the people let out a heaven-shattering cheer after a short silence, and the sound shook the sky, and the earth was shattered!

Seeing this scene, Zhang Ning finally breathed a sigh of relief, and a confident smile climbed back onto his face.

"Ziyou, how did you do it?" Erin, who reacted, grabbed Zhang Ning's hand, her face flushed with excitement, she knew very well what the scene in front of her meant, which meant that the entire human defense system had made another leap! With this huge net, she believed that human beings would be more confident when they faced demon beasts again. "This canopy is much more powerful than the Guardian of the Universe!"

The Cosmos Guardian Cover can only defend against enemies, but this giant net, which Zhang Ning named Tianmu, can actually kill enemies while resisting enemies, which is naturally much stronger than the Cosmos Guardian Cover.

At this time, everyone on the city wall also reacted, looking at Zhang Ning excitedly, and the blazing gaze could almost cook Zhang Ning.

"Haha, I knew, I knew, my lords must have a way to protect Cartel City. Ratmund clenched his fists with excitement on his face, and jumped in place several times in a row before relieving himself, at this time, he looked like a beloved young city lord. "I knew it!"

Compared to the excited Ratmund, the alchemists seemed much calmer, of course, it was only relatively speaking, and it was not difficult to see the excitement in the hearts of this group of old people from their constantly shaking beards.

At this time, the old people all looked at Zhang Ning with burning eyes, expecting him to answer Erin's question. Because of the inscription of the alchemy demon pattern, they probably knew the concept in it, but they still wanted to hear Zhang Ning say it.

"Actually, it's nothing, the canopy can actually be said to have modified and upgraded the Cosmos Guardian Cover. The text in his left eye jumped, and Zhang Ning pointed to the giant net in the sky and said. "As you know, the Cosmos Guardian Shield is a guardian shield formed in the air by spreading the energy of the magic crystal in a special way. With the energy of the magic crystal as a backup, the power of this guardian cover is needless to say, but this will invisibly cause a lot of energy loss. After all, although there are many demon beasts, they don't attack every place, so I simplified the guardian cover into a light net, so that the energy consumed is reduced. ”

After a pause, Zhang Ning continued. "Of course, although this can also reduce the consumption of energy, but in my opinion, it is still not enough, I don't know if you have found it, all the attacks of the monsters are actually intervaled, which means that the guardian cover is actually not under the attack of the monsters all the time, which also means that there is a lot of energy consumption in the interval when the monsters are not attacking. Therefore, I easily transformed the optical network into an attack sensing mode, only when I sensed that an enemy was attacking, the optical network would transmit energy from other places that were not attacked, so that the part that was attacked increased in a very short period of time, so that the monster would return in vain. ”

"Ziyou, if the demon beasts attack at the same time, how can the canopy resist the attack of the demon beasts?" asked Erin, tilting her head.

"Of course, it's to speed up the absorption of energy. Zhang Ning stepped on his feet, and around him, nineteen magic crystals were emitting a faint light, reflecting the huge light network in the sky.

"I see. Erin nodded, her eyes flowing. "I believe there must be many people who have the same idea, but there are not many people who can put their ideas into reality like Ziyou. ”

"It's not much, it's just nothing!" Bobby exclaimed. Everyone knows that the Guardian of the Universe is a waste of energy, and everyone wants the Guardian Shield to have the ability to automatically sense attacks, but none of them can do this!

Whether it is inducing energy, automatically extracting energy or directly extracting the energy on the magic crystal, this kind of alchemy pattern is unprecedented, unthinkable, not to mention making it, few people even think of it.

"With Master Ziyou here, Cartel City will definitely be able to hold it. Bobby sighed from the bottom of his heart and spoke everyone's mind.

"Ladies and gentlemen, our crisis is not over yet. Looking around at the excited crowd, Zhang Ning poured cold water on them in time. "Although the canopy doesn't need to provide as much energy as the Cosmos Guardian, the light network still needs magic crystals to provide energy after all. There are only nineteen magic crystals left in the city, and according to my estimates, we will only be able to hold out for a few more hours at most. This is not the time to cheer!"

Seeing everyone's instantly gloomy faces, Zhang Ning smiled. "But don't worry too much, we have another treasure besides the canopy. His eyes flickered, and finally fell on the dazzling magic cannon that Ratmund had brought back.

......

The dazzling magic cannon is made of a special material, in this dark night, the cannon body flashes with a faint light, there is a sense of beauty caressing the cannon body, a feeling of warmth like jade is transmitted, Zhang Ning couldn't help but sigh secretly, this magic cannon is really not something that ordinary cities can configure.

The structure of the Glare Magic Cannon is actually not complicated, compared to the Cosmos Guardian Cover that every city is equipped with, the Glare Magic Cannon is simpler and easier to understand. However, the dazzling magic cannon just can't be popularized.

For no other reason, the materials needed for the Glare Magic Cannon are very scarce, and even if all the power of the human race is exhausted, the materials found are only enough to make more than a hundred Glare Magic Cannons.

Zhang Ning missed the battle of survival, and he didn't know many things, but he had a certain understanding of the dazzling magic cannon, because on the night of chatting in the hotel, Melissa had mentioned the dazzling magic cannon with envy. Atwell is a small city, and the financial resources are not strong enough, so naturally they can't afford to buy the Glare Magic Cannon, but this does not prevent Melissa from yearning for the Glare Magic Cannon.

"If only we could have a dazzling magic cannon in Atwell, even if I had to reduce my life by forty years. ”

Thinking of Melissa's words at that time, Zhang Ning couldn't help but smile, and at the same time, silver light flashed in his eyes, and information about the dazzling magic cannon immediately surfaced in front of him.

"My lord, do you want to replenish the energy of the Glare Magic Cannon?" Ratmund rubbed his hands together and squatted beside Zhang Ning diligently.

"Nope. Zhang Ning smiled. "I'm going to reinvent it. ”
