After traveling through time, I want to become a magical omnipotent saint

"Little sister, the location of this mission is this cave entrance."

Higgindale and Isabella are standing in the cave and talking.

"This mission involves the base of the Magic Group, and I need to do some investigation."

After Higindale finished speaking, he took out a translucent crystal from the void. The crystal emitted colorful light, which contrasted with the gray terrain and rainy weather near the cave, making the light of the crystal particularly dazzling.

Isabella waited quietly...

This crystal is called the Crystal of Retrospection. It is a special magical tool that can replay all human figures within a hundred meters in the past three days.

In Isabella's eyes, the light and shadow cast by the crystal was the entrance to the cave where she was, but she was looking down from a God's perspective.

Isn’t this just surveillance playback?

"Oh?"

Higindale glanced back at Isabella.

"Little sister, why aren't you surprised or curious? This special magic tool only exists among high-level magicians, and only two out of ten people can have it!"

"Nothing, can you speed it up? I'm bored too, staring at an almost still picture!" Isabella complained lazily.

"How do you know you can fast-forward? Have you ever seen it?"

Isabella shook her head. Although it was an eye-opener, as a time traveler, this kind of scene was just like that.

An hour later, after watching the entire process again, he did not find any signs of anyone moving around, which made Higgindale feel even more suspicious.

Then, he released the space gap and took out a black cube, which was then suspended in Higindor's cupped hands after being infused with black magic.

Inside the cave, some strange magic elements were fluctuating and flowing towards the black magic cube.

"What is this?" Isabella asked curiously.

"This is a magic element sensing stone, which is also a special magic tool. Since Group C and Group B are both out investigating spies, everyone will carry one to detect magic elements in unknown areas and judge the threat level of the enemy based on the strength of the magic element flow."

Isabella nodded: "I see! You don't look young, but I didn't expect you to be so cautious!"

"Not old? To be honest, I'm already sixty-six years old. If we compare the life span of elves to that of humans, I'm probably equivalent to a six-year-old human."

"Ah! This... one to ten! The lifespan of you elves is too long!"

Isabella felt bored and kept talking.

After the exploration, Higindale walked into the cave entrance and lit a blue halo in his palm to illuminate the cave.

"There are elementary monsters in this cave, but there are still many places in the depths that have not been explored. For now, I suggest going forward three kilometers and releasing another exploration."

On the way, the primary monsters they encountered were mostly demonized poisonous scorpions, demonized salamanders and demonized bats. Isabella only needed to move her fingers slightly to kill these monsters that attacked people.

Higgindale carefully observed his surroundings, even making sure to take a clear look at every stone under his feet before he walked past.

An hour later, when they had gone almost three miles into the cave, Higgindale stopped and looked at the structure inside the cave, muttering to himself.

"There are no stalactites, no water at all, and the stones on the road are all fallen off the mountain wall. There are no rock layers, and there is no unique ecology of the cave. This shows that this cave should not have appeared for more than 300 years. However, it has reached its current location..."

Higgindale pointed to the depths, and the light emitted by a ball of light grew larger, illuminating an open cave hall. The space inside the cave hall was so large that it could accommodate a castle 100 meters high.

The cave suddenly became chaotic. A group of demonized bats were awakened and started rioting.

Isabella waved her hand casually, and countless lightning bolts struck the cave hall.

Boom boom boom——

Nearly a hundred primary demonized bats died at Isabella's hands.

Higindale held out a purifying crystal.

"You can use it. In order to save my magic power, I won't remove the symptoms of magic invasion for you."

Isabella hesitated for a moment and accepted Higindor's gift. In fact, she didn't need any purification crystals, but in order to hide her other cards, using two types of magic in front of her was enough.

"There is no road ahead..."

Higgindale checked the situation again.

"But there is a huge rock blocking the entrance deep behind the cave hall..."

Isabella followed behind her, silently observing her surroundings, but the deep darkness around her made her feel vaguely uneasy. She wished she could release bright magic to fill the entire cave hall.

Higindor released space magic, and the large-scale space distortion moved away a boulder weighing nearly a hundred tons. Suddenly, a magic restriction appeared, and a dark red magic circle blocked the entrance, making it impossible to detect the situation inside.

"Alas! This is a big trouble..." Higgindale sighed deeply, "I am not good at deciphering the magic circle restrictions, because I always use space magic to forcibly break it. Please wait for me for a while..."

While Isabella was waiting, she continued to secretly absorb the magic power of the monsters that dissipated in the cave hall and replenished her magic source. Her magic source became twice as powerful, and she was just a little bit away from being promoted to the first level of an intermediate magician.

After waiting for half an hour, Higindale completely cracked the entrance ban. The moment the ban was broken, a deep and strange wind whistle came from the cave.

Higgindale was about to conduct another probe but was stopped by Isabella.

"I don't think this place is right. This magical restriction must be sealing something, so there's no need for us to go deeper!"

"What? Are you scared? Little sister, we have only just arrived. In the depths of the cave, besides monsters, there are also rare human footprints. As for the traces of the Magic Group's base, I didn't see any. If we don't go deeper, who knows what shocking secrets are hidden. This base is the hidden base of the Magic Group. Even if there are enemies, they are no match for you and me, but it is still necessary to follow the necessary procedures..."

At this time, a sound similar to the howling of dozens of humans came from the cave, sharp and piercing.

As soon as Higgindale took out the black magic cube, a large amount of gray magic flowed into her hands...

"Oh no! It's a monster! It's coming towards us!"

Higgindale became alert and his eyes became sharp.

"We can't leave them alone. Once they leave the cave, the people outside will be in danger!"

Higindale activated his flying cloak and flew deep into the cave.

Isabella followed closely behind her.

Isabella was dumbfounded by the scene that came into her eyes.

There is actually another cave under the ground, and the width of the cave ranges from 500 to 800 meters.

There are countless stone arch bridges in the abyss under your feet, roads surrounding the stone walls, and blue ghost lights scattered on the stone walls of the abyss.

It's like coming to an underground city.

Thousands of stone monsters walked towards the exit above.

From Isabella's current perspective, the abyss looks like a huge ant nest that has been sealed off, with tens of thousands of intermediate monsters walking around - stone monsters.

Isabella released lightning magic, but the intermediate monster Stone Monster had strong resistance. An attack from an ordinary intermediate magician had no effect at all. Only after injecting magic resonance to strengthen the lightning element could the monster be damaged.

The insulating stone was struck by lightning, producing countless sparks. It took ten attacks to kill a monster, which was too inefficient.

Higindol instead took advantage of the terrain and used space magic to distort the movement space of the stone arch bridge, pushing these monsters into the abyss.

The effect was very good, but within ten minutes, Higindor took out a bottle of potion and drank it, which significantly replenished his magic power source.

Isabella's source of magic power was also exhausted. She had been consuming magic at a high rate, and Isabella once again experienced the feeling of magical fatigue.
