As the radiation contamination index rose, Stephen visibly felt that the mana surge in his body was a little more manic than before.

In the natural world, the radiant energy force field can easily interfere with elemental energy, and generally speaking, areas with more severe radiation will become [Chaotic Magic Areas], such as the Death Swamp area that has withstood the explosion of the Eternal Blazing Sun. And if this radiation pollution index is applied to the human body, it will increase the difficulty of one's own energy control, and may lead to the failure of the spell. If it's better to just have radiation contamination on your body, but you are most afraid of having radiation contamination on your body, and then you accidentally enter the chaotic magic area, then the difficulty of casting spells will increase exponentially, and you must have a high level of concentration to control it.

"It's best not to take potions for the next month. Stephen said to himself.

His physique is still 0.5 short of reaching 10 points, according to the effect of the aboriginal potion, in addition to the explosive quality improvement at the beginning, he will slowly increase his physical fitness later, and he can slowly reach it by relying on meditation.

It's getting dark.

Stephen tidied up and went out, and compared to the enhancement of the attributes in the physique, the increase in strength was a little more obvious.

Now he can be said to be able to lift a weight of about half a ton without difficulty, and brute force alone is enough to crush most knights. It's no wonder that the wizards of this world are completely above other professions, and an existence that can melee combat, cast spells, and be infinitely powerful is too perverted.

There's nothing going on here at the academy for the time being.

Jacob signed up for five courses in one go, the twin sisters were studying advanced combat training, the Witch Liana was still stationed on the island, and the Mograine Wizard had set off for the desert realm.

Stephen doesn't have a course scheduled yet, and the academy doesn't have any mandatory requirements for official blue-robed wizards.

Most blue-robed wizards will frequently accept tasks to earn resources to improve their strength during this period, but Stephen's net worth is still quite a lot, and there is no need for many tasks with average pay. So after going to the mission hall to hang up a quest to buy a 'high-level flame essence', he prepared to go to the library for a walk and start working on his next thesis by the way.

Now.

"Stephen's Low-Level Spell Optimization" has become a compulsory course for wizard apprentices, and even related books have spread outside the Five Rings Tower, and are scrambling to be read by people from other academies, including dark wizards, many people have read his papers. At present, Stephen is not suitable to come up with some too high-level knowledge, so he chooses among the special spells in his memory, and chooses one of the low-level spells to be published.

This spell is called [Detect Life].

This is a two-ring level general school spell, it is a detection spell, after casting, it will emit a faint spell aura with a diameter of about 100 meters, and then scan out all living creatures within the perception range, but this spell has no effect on undead creatures and mechanical structures.

Stephen released an improved version of his own optimization, the original version was a three-ring spell, and he optimized the spell node to become a two-ring spell.

With such a new spell published, and a very useful detection spell, the Five Rings Tower had to give Stephen a groundbreaking evaluation anyway. If a new spell born in the academy is willing to be made public, then the contribution is very high, and Stephen just paved the way for his own innovation ability, and he still has a lot of spells to announce in the future.

The next day.

Stephen received a summons from the owl, probably because of the lack of pseudo-dragon magical creatures in this world, many wizards' magic pets are cats, crows, owls and other creatures, and some of the more awesome people who are proficient in zoology and animal taming may choose large beasts.

The mission hall informs Stephen that the quest he hung out has been completed.

Stephen asked for the 'High-Grade Flame Essence' in the mission hall yesterday, and directly gave an offer that was two percent higher than the market price, which cost him 120 magic stones. But fortunately, the high price has high efficiency, and today a wizard completed his task and brought back the high-level flame essence that Stephen needed.

Soon, he was in the mission hall.

At this moment, in the room at the back of the hall, a handsome wizard with long fiery red hair was waiting for Stephen's arrival. He is a battle wizard belonging to the elemental pool, and it seems that he is a member of the flame faction in the four elemental passages, and the people of this faction have the strongest combat effectiveness, and the leader is the red-robed wizard of Victor.

The elemental pool consists of four passages, which are respectively connected to the elemental plane of earth, water, wind and fire, but it is the inner or outer layer of the elemental plane Stephen does not know, because the conditions for these elemental passages to enter are relatively harsh.

Due to the primitive techniques of the Indigenous shamans, these passages need to be converted into a semi-elemental form to enter.

In other words, only blue-robed wizards and above who belong to the elemental pool can enter and exit safely, and other wizards, such as those from the Botanical Garden and the Astrological Observatory, may be in danger of their lives if they enter rashly. High-level flame essences must be a little inside the fire elemental plane to fall out, and Stephen must make a high-level fire resistance ring to safely enter and exit the inner layer of the fire elemental plane.

The handover was quick.

After Stephen got the high-grade flame essence, he nodded and turned to leave.

Immediately after returning to the Botanical Garden, he began to write a new thesis, on the universal spell "Detecting Life".

The next three days.

Stephen spends a lot of time making a high-level fire ring, because he has almost everything he has prepared, and he can go to the fire elemental plane once, one is to explore the elemental plane of this world, the second is to find a way to enslave two or three lava elements, and the third is to find rare materials to build the obsidian factory.

The Obsidian Factory is an important part of the Floating City.

Because this is a pre-building, with the Obsidian Factory, Stephen can next build the Stone Golem Factory, making the Granite Golem, Marble Golem, and Obsidian Golem, respectively, the latter is more difficult to craft, but the combat power is already faster than the Steel Golem.

Then, with the Stone Golem Factory, Stephen can also be integrated and upgraded to a high-level Golem Factory, making the most commonly used Clay Golem, Stone Golem, Steel Golem, and Diamond Golem.

As for the latter, the diamonds in Stephen's hands are not enough to make a fraction of a golem's diamond.

Let's wait until we can use alchemy to refine diamonds in batches later.

However, in order to do so, he had to find a way to craft a legendary-level alchemy stone.
