Celestial Era: The Rise of the Full-Time Enhancer

Thyrus arrived at the site where he was told to investigate. According to Calidia, the source of the massive detection scan used on their city had come from here.

They don't know whether it was from a complex Mana Art or they used a Magic Tool to do it.

Nevertheless, she wanted him to find any traces of the person who used it and report it back to her. It seems that they wanted to create a countermeasure after knowing what kind of detection art was used in their city.

"Hmm… It's really quiet around here…" Thyrus muttered after looking around the hill.

After a while, he found a good spot to observe the city and used a Tier 3 Mana Art.

"Wind Tracer…"

Whom!

From his feet, a shockwave was created spreading throughout the hill to the forest below.

It only took eight seconds before this wave of energy reached the edge of the forest and send feedback to Thyrus.

"Weird… There should be some beasts around here… They were all gone into hiding?" Thyrus was confused.

His wind tracer did not detect any movement of beasts living on the hill or the surrounding forest.

It means that they have either died or left this forest to find a new home. However, that doesn't make sense since he can still find traces of beasts that were living here just a few minutes ago.

He can only think of another reason. Perhaps, all the beasts are hiding and unmoving while concealing their aura. If that were the case, even his wind tracer won't pick up their movement.

As he was thinking of summoning another wave-type Mana Art, he felt a sudden distortion in space. This is something that he's extremely familiar with!

"A portal?"

Thyrus looked above with wide eyes… There was a sudden tear in the space above the hill and several Dragon Riders came out!

He wasn't sure whether it is deliberate but thankfully, the portal wasn't large enough to let a warship pass through so only the Dragon Riders or perhaps humans can pass through it… They shouldn't worry about warships bombarding them…

"Hmmm?" Thyrus received a signal from the Tower to retreat.

Needless to say, his investigation was no longer needed since the enemy has appeared.

With a swift movement technique, he returned to the city and confirmed that the guards were now waiting for the enemies to arrive.

He looked at the Kayser Tower and its Mana Cannon seem to be targeting the hundreds of Dragon Riders that keep pouring out of the portal.

'Are we waiting for them to complete their preparation?' Thyrus mused as he observed the enemy formation. If he was the one in command of the defense, he would stop them from coming out of the portal by bombarding them with artillery and cannons.

However, Calidia doesn't seem to have plans of interrupting them. He can only think that she was waiting for all of them to appear and eliminate them in one fell swoop.

This might also be a good idea if they wanted to end this battle once and for all.

"Sir Thyrus… I will be joining the defense… Please, lead us."

Suddenly, Thyrus heard Magnus' voice behind him. He then looked at the young man who is now wearing his full battle gear. He is accompanied by several magicians who were probably guarding other stations and was transferred here in a hurry.

Currently, there are no Grand Magus here aside from him so it wasn't a surprising thing that he was assigned to lead the magicians.

As for the knights, they will be led by a Grand Knight under Calidia's command.

"Alright… So far, only Dragon Riders are coming out. They will be quite tricky to deal with… But we have the City Barrier to protect us. We just have to wait for the portal to close and Calidia's signal to attack."

"So we're really waiting for them to finish their formation, huh…"

"Yes.. leaving some of them behind will just create more trouble in the future so this might be a good plan..." Thyrus replied…

Suddenly, he saw the pillar light coming from the Magic Tower.

It was directed to the flock of dragon riders hitting them directly!

Apparently, the second the portal was closed, the Mana Cannon was fired in an instant… As expected, Calidia has really planned this out.

The pillar of light wasn't small. It was wide enough to hit three or four dragon riders…

Since they were lined up neatly, the sudden burst of fire hit about 20 of them at the same time!

There were about 500 Dragon Riders that appeared this time so the cannon could've hit more but it was stopped by an Aura Knight who is probably the leader of this battalion.

The beast he was riding on was also larger and equipped with better armor and weapons.

"A tricky one has appeared… That's not a simple 3-Star Aura Knight… It's better to focus on his subordinates first. Don't waste your energy fighting that knight… Sending low-level Mana Arts to distract him is more than enough." Thyrus immediately said to the group of the Magicians under his command.

He already had a hunch about the identity of this man. After all, there aren't many 3-Star Aura Knights that had reached this level within the Black Tower.

Another pillar of light came to attack this man but as expected, his sword was able to cut it in half… Although it hit five of the Dragon Riders behind him, the force was already neutralized and they were only slightly injured from the scattered mana beam.

"It is the 14th Tower Master… Ugh…" Thyrus grunted as he knows this Tower Master. This man is not only a 3-Star Aura Knight but also a Penta-Caster Grand Magus.

Perhaps, if they have five Mana Cannons aiming at this guy, it's possible to bring him down without approaching him.

However, Kayser Tower only has one Mana Cannon since it's really an expensive thing.

"Tsk… Just stick to the plan… The Magic Knights will deal with these people if they managed to breach the barrier… Target one of the Dragon Riders and fire at them!"

Thyrus ordered as they started their bombardment. In the meantime, he also cast four Mana Arts at the same time.

Thyrus knows that he can't fight the 14th Tower Master since he's only a newly appointed Archon. However, he doesn't really need to fight him… Once all of his subordinates died, this person will naturally retreat since there was no way he would siege the city alone.

No matter how strong he is, his Mana Core isn't unlimited after all.
