Without Alona, ​​I can only use the airdrop system.

8:00 AM, Tonggong Ancient Church.

Today marks the day when Gerina and the Holy Trinity Eden Treaty were signed.

Because this is a significant event, both Ghenna and Trinity Colleges are closed today, so the colleges are packed with students.

Fortunately, the order at the scene was managed by the Trinity's Department for the Realization of Justice and Gersena's Disciplinary Committee. Although there were many people, everything was well-organized.

As for the teacher, he and the doctor were quietly waiting inside the cathedral.

The doctor is on the phone, seemingly communicating with someone.

However, perhaps because the Eden Treaty was about to be signed and Arius's attack was imminent, the teacher, who was under considerable pressure, couldn't wait any longer and wanted to go out and slack off.

"Ugh... I'm so bored..." The teacher stood up and stretched, then looked at the professor. "Professor, how about we go for a walk together?"

“No problem.” The doctor had just finished his call. “But aren’t you going to find a guide?”

"Oh, that's true." The teacher wasn't very familiar with the ancient church of Tonggong either, so she called out to Hinata, the super-strong nun sitting in the front seat, "Um... Hinata, the professor and I would like to take a look around this church. Could you show us the way?"

Hinata turned around after hearing the voice, her expression very happy: "Ah! It's so great to be able to help you, teacher!"

After saying that, he stood up and said, "Let me take you there!"

"Okay, thank you!"

Afterwards, led by Hinata, the teacher and the professor visited the ancient shrine of Tonggong.

Along the way, Hinata shared a lot of knowledge about the building. The teacher and the professor were listening attentively, and the professor even asked Hinata a few questions about the history of Trinity.

However, Hinata's knowledge was not that extensive, and she was stumped by some of the questions the professor asked, only able to answer that Sakurako and Mary might know.

The visit went by quickly, and since Sakura was about to reach the ancient chapel, the three decided to return to the interior of the church first.

However, the next moment, the doctor suddenly squatted down, then clutched his stomach, seemingly enduring severe pain!

"Huh?!" Hinata panicked. "Professor, what's wrong?!"

"The toilet, where's the toilet?!" The doctor looked like he couldn't hold it in any longer. "I feel a primal force surging within me, I can't hold it in any longer!"

Seeing this, Hinata immediately pointed the way: "To find the restroom, turn left at the front of this corridor!!"

"grateful!!!"

After saying that, the doctor disappeared in a flash.

"Why did the doctor suddenly get an upset stomach?" The teacher was still a little confused, but then he suddenly realized what was going on.

Could it be that the Arius Academy's attack is about to begin?

Suddenly, the voices of the Terran armed forces also began to ring out:

Main Quest Begins: Defend the Great Cathedral

Reward: The cost of using Terra Armor Combat Mode has been significantly reduced.

The teacher's expression changed.

"Hyuga, there's an emergency!"

"Hey, teacher, you have diarrhea too?!"

"No, take me back quickly, I have something to tell everyone!"

"Ah, okay... okay!"

Seeing the teacher's suddenly serious expression, Hinata understood that this was probably what the teacher had told them before: that Arios Academy was going to launch an attack on the ancient sanctuary in Tonggong.

After all, this is where the Eden Treaty was signed.

.......

On the other side, a tea and snack shop.

Zi looked out the window and saw a missile that no one else had noticed fly by.

"Zi, what are you looking at?"

Hifumi looked at Azusa with a puzzled expression.

"Oh no, it's them...!"

Zi felt something was wrong and suddenly stood up.

"Azusa!?"

Hifumi immediately grabbed Azusa: "Is there something wrong? Can you tell us all?"

Hanako and Haru, who were also sitting at the same table, looked at Azusa with a puzzled expression.

“…” Zi recalled her conversation with Hifumi and the other two in the classroom and took a deep breath.

"They're Arius's people! They're definitely trying to sabotage the signing of the Eden Treaty!"

Suddenly, an explosion rang out outside!

The missile that was flying in the air exploded for some unknown reason!

"!?"

The four students from the tutoring department rushed out of the tea shop. Of course, other Trinity students who heard the explosion also ran out out of curiosity.

Seeing the missile explode before it even hit the ground, Zi breathed a sigh of relief.

But the next moment, more missiles suddenly appeared from the sky, striking the entire territory of Trinity!?

"!?"

All the students present felt a sense of foreboding, and the scene suddenly descended into chaos.

The four students in the tutoring department huddled together, leaning on each other to avoid being swept away by the crowd.

However, the next moment, another unexpected event occurred. Just as the missile swarm was about to approach the building, it suddenly seemed to hit a wall and exploded!

This unexpected turn of events left all the students present feeling relieved, as if they had escaped unharmed.

"What on earth is going on?!" Hifumi looked at the incomprehensible situation, somewhat bewildered.

"This... I don't know either..." Zi also shook her head.

However, Zi knew that her teacher possessed great strength.

Could it be that all of this was a joint effort between the teacher and that PhD?

However, Zi had a premonition that things wouldn't end so simply.

"Everyone, let's stick together and get ready!" Azusa reminded Hifumi and the other two, "Arios's offensive might be coming soon!"

"!!" Hifumi made a quick decision, took out her phone and started typing, seemingly sending something.

The next moment, screams from students rang out in the distance.

"Monster!!!"

"Ghost!!!"

"Run!!!"

"Quickly find a safe place to hide. Hand this over to the Justice Implementation Department and the Disciplinary Committee!!!"

.......

The scene became chaotic again.

"Besides some special automated units, Ariana Academy even has Sisters of Justina. How did Ariana Academy manage to summon them...?" Even the knowledgeable Hanako couldn't help but be surprised by the attacking army. "And there are skeletons and zombies too. I thought I only saw things like that in movies and games..."

"There are just too many of them..." Zi's gaze turned serious. "And their main direction of movement seems to be towards the ancient sanctuary of Tonggong..."

"Everyone, please listen to me," Hifumi said, revealing her idea. "Our teacher might be directing the students in a battle against Arius Academy right now. He helped us so much back in the tutoring club, and I want to help him too!!"

"But Hifumi-chan, given the number of enemies present, if we go straight in, I'm afraid..."

"The Crusader we drove to the beach is still parked at the Justice Realization Department!" Hifumi said decisively. "We can drive it there to support our teacher!"

"I also contacted some friends for support, and we met up at the Justice Realization Department!"

"Friends?!" Koharu looked at Hifumi with a blank expression.

"Hehehe, I didn't expect Hifumi-chan to have such good interpersonal relationships~." Hanako laughed.

"Alright!" Azusa agreed with Hifumi's plan. "Let's get started without delay!"

Just as Hifumi and others were advancing toward the Ministry of Justice, countermeasures had already been prepared at the site of the Eden Treaty signing.

“3队、4队开火，1队、2队撤退换弹，5队、6队预备！！！”

Under Ako's command, the members of the Gehenna Disciplinary Committee were firing in an orderly fashion.

Meanwhile, Hina was also suppressing fire on another position.

This is also the result of the special training the doctor gave them before. Now the Disciplinary Committee's group combat strength has reached a level that is much stronger than before.

The members of the Pandemonium present also launched an attack under Iroha's guidance, while Iroha provided artillery support using Toramaru.

However, the skeletons and zombies that were leading the attack felt no pain and were tougher than expected, making them difficult to repel with bullets.

As a result, the Holy Trinity side became somewhat flustered.

Nagisa suddenly fainted after the attack on Arios Academy began and has not yet woken up.

Meanwhile, members of the tea party also mentioned that the artillery positions in the distance had been completely destroyed by the people from the Arian Academy.

The miscellaneous members of the Justice Realization Department were thrown into disarray, and even with Hasumi's organization, it was difficult to achieve any results.

Fortunately, the teacher arrived in time to direct the scene, and the chaotic formation of the Justice Realization Department was stabilized a little.

Crane City charged directly into Arius's vanguard, attempting to break through their lines.

At the same time, the teacher also instructed Hasumi and Mashiro to try their best to hit the Arios students behind them.

After all, they are the irreplaceable vital force.

However, Hiyori, a member of a special squad, was on Arios's side. She kept interfering with Hasumi and Mashiro's sniping, making it very inefficient to deal with Arios's students.

With the addition of a large force of undead, mechs, and Justinian believers, even with the presence of members from the Disciplinary Committee, the Pandemonium, the Justice Fulfillment Department, the Sisters' Guild, the Tea Party, and the Knights of Salvation, they could barely hold the area around the ancient sanctuary of Tonggong.

Moreover, Saori, Akiko, and Misaki didn't even make an appearance!

The only good news is that their heavy weapons cannot damage the ancient sanctuary of Tonggong; an invisible, hard protective shield can completely withstand the attack of all of Arius's heavy weapons.

This protective shield was naturally the doctor's "arrangement".

The teacher was thankful that he had chosen to trust the doctor; otherwise, the entire Holy Trinity would have long been turned into a living hell by missile and heavy weapon bombardment.

At this point, seeing that the members of the Justice Realization Department had coordinated their efforts, the teacher used the Shiting Box to connect everyone present via radio for unified command.

Because the offensive was too intense, the battle lines were too large, and no powerful enemy had appeared, the teacher could only use the power of the turbid bud to strengthen all the students present.

"Please note, teacher, that the current coverage is too large, which will weaken the enhancement effect to some extent!"

This Terran weaponry is really too awesome.

The teacher cursed inwardly.

However, he cannot reveal his trump card in the battle mode at this moment. He can only slightly enhance it with the power of Zhuodi and then use his overhead ability to command.

Perhaps due to the immense pressure brought about by the disadvantageous situation in the battle, the teacher quickly became familiar with the busy multi-front command.

However, unified command did not bring any advantage to the students.

On the contrary, the number of wounded is slowly increasing.

Sometimes, to make up the numbers, Gersena and the Trinity student council would cross over and work together on missions.

Perhaps because the situation was extremely critical, the usual conflicts between the students of the two colleges were greatly reduced, and their attention was focused entirely on dealing with the enemy.

Even so, the students would get tired, while the attacking undead and mechs, as well as those blue nun followers, seemed to have endless stamina and numbers.

Moreover, Arius's offensive suddenly accelerated, making it even more difficult for the already disadvantaged teachers to keep up.

Do you want to use Terra Armor's combat mode?

Although the teacher knew that the truly powerful figure had not yet appeared, he had no choice but to do this in order to prevent more students from getting hurt!

Just as he was about to use the Terran weaponry, a tank and a combined arms force of infantry and tanks composed of many students burst in from the side of the Arius Academy's attack!

"The Crusaders?!"

The teacher was shocked.

Could it be Hifumi and her group?!

The combined arms force advanced very quickly and soon arrived at the teacher's position!

"Sorry, teacher!" Hifumi popped out from the Crusader's head, "We're late!"

Immediately afterwards, the other members of the tutoring department also disembarked from the Crusader.

"Hi, teacher, did our reinforcements arrive just in time?"

"Hifumi?! And everyone from the tutoring department!" The teacher was overjoyed. "You've arrived just in time!"

"We're here too."

At that moment, five more familiar figures appeared before the teacher.

"Everyone in Abydos!?" The teacher was so moved that she almost cried!

"Hehehe~, Hifumi asked us for help, and it just so happens we have some free time." Hoshino said lazily, "But there are so many enemies here, we should get some rest when we get back~."

The teacher said from the bottom of her heart, "Thank you!"

"We've come to help too, teacher."

"Everyone from Convenience Store 68!?" The teacher didn't expect Aru to come here too.

"The professor contacted us beforehand and even paid us a substantial sum in advance." Aru was also very happy at this moment. "We can get money and help our teacher at the same time. It's a win-win situation!"

At the same time, other students who knew the teacher also responded.

"Teacher, thank you for your help back then. My friends and I are here to help you too!!"

"Teacher, our Self-Defense Forces are all here. Hmm? You mean the one next to you? Her name is Usa Suzusa."

"Teacher! Teacher! Although we don't know what's going on, we won't stand idly by when we see Trinity being destroyed!"

"Teacher, everyone from our dessert department is here after school to help out!"

"Hahaha! Teacher, the hot spring development department is here to lend you a hand!!"

"Hehe, the same goes for the Food Research Association."

.......

"Teacher, the situation is critical, so let's not waste any more time," Hifumi commanded. "Everyone, let's go!"

"Hehehe, Hifumi-chan is becoming more and more like a leader~."

"Awooooo~!!"

Soon, the support team joined the battlefield and immediately provided great assistance to the defending team, and even the battle line began to slowly advance!
