Straight in one direction, Bai Ming advanced for more than ten miles, repelling more than a dozen waves of large and small fish-man gangs, and then faintly saw a piece of land.

Feeling the solid ground on the soles of his feet, Bai Ming nodded with satisfaction.

The land is not large, only a few hundred square meters, but it is extremely flat, full of shrubs and weeds.

"It's decided that this is the place, what do you say, adjutant?"

"Your Excellency the Legion Commander is happy."

Ignoring the adjutant's sullen complaint, Bai Ming clicked on the building module, found the Arcane Research Institute, and directly chose to come.

With Bai Ming's command, a small tower model suddenly appeared in the void, obviously only about twenty centimeters, but the appearance structure was clear and abnormal. The cylindrical tower is covered with mystical runes, adding a bit of mystery to the white jade-like outer wall.

As soon as Xiao Tafu appeared, he rose in the wind in Bai Ming's stunned eyes. In just a dozen seconds, it turned into a giant tower with a height of more than 100 meters and a diameter of 20 meters.

Looking at the gorgeous and unusually huge tower in front of him, Bai Ming's saliva was about to flow out. Hurriedly walked towards the giant tower.

But when he got closer, he was immediately dumbfounded. "Adjutant, why doesn't this tower have a door?" The whole giant tower is like a whole, except for the windows on each floor, there is not even a single gap.

"Your Excellency Legion Commander, please set the unlock password first, the Arcane Research Institute currently supports fingerprint unlocking, voice-activated unlocking, and iris unlocking."

Bai Ming suddenly sighed. "This magic is moving closer to science."

"Set the iris unlock for me, and add a password." Bai Ming thought for a while and then said, "The password is set up, you don't know anything about power." ”

What Bai Ming didn't expect was that his casual words would become a warning word for the entire demon plane in the future. Whenever those who are complacent because they have gained strength say this, they immediately put away the pride in their hearts.

With the completion of the verification of Bai Ming's iris, a circular arch more than one zhang high immediately appeared on the giant tower.

Walking into the tower, a huge empty space appeared in front of Bai Ming's eyes.

"I didn't even send furniture, it's really picky!"

However, complaining and complaining, in fact, Bai Ming is still extremely satisfied.

A single-storey space more than 10 meters high, except for a cylinder in the middle, all other areas belong to the usable area.

Walking into the cylinder, Bai Ming realized that this thing was actually a magic version of the elevator. It is no wonder that the giant tower more than 100 meters high, if there is no elevator, is indeed quite inconvenient.

Opening the elevator door, Bai Ming began to check the research institute floor by floor. There is basically no difference between the first and seventh floors, all of them are empty.

It wasn't until the eighth floor that some changes occurred. The entire eighth floor is occupied by huge bookshelves. Bai Ming made a rough estimate. It would take hundreds of thousands of books to fill the shelves here.

But now there was only one lone book on the shelves.

When he opened this book, Bai Ming's eyes couldn't help but light up, this was an apprentice high-level arcane art called Mirror Returning Technique. The principle is to create an arcane round mirror through the magic power in the body, which can reflect the enemy's spell attacks to a certain extent. Physical attacks are ineffective, and they have a stronger reflection effect against ray spells, in particular.

What's even more amazing is that Bai Ming actually directly generated relevant skills in his body when he watched such an arcane art. And the adjutant's explanation is that this is a benefit as a corps commander, and the others have to learn honestly.

After experimenting with it, Bai Ming found that this mirror return technique was indeed quite useful, although it could only be used to reflect some spells with low strength. However, this mirror return technique perfectly solves the problem that the thermal energy rays cannot be bent.

It only takes a mirror return technique to be released in advance, and then through refraction, Bai Ming can completely perform a 360-degree strike without dead ends.

Without hesitation, he spent energy points to point the mirror return technique to the point of unparalleled in the world. Bai Ming even discovered that he could perfectly control the form of the Arcane Round Mirror. When it becomes a concave mirror, it can concentrate several rays into a more powerful ray. When it becomes a convex mirror, the rays can be scattered.

Fortunately, the buildings in the Arcane Research Institute are all indestructible, otherwise they really wouldn't be able to withstand Bai Ming's toss.

"Adjutant, are the arcane spawned in the institute completely random from the first to the ninth order, or will there be any rules?" The first arcane art generated by this was something that Bai Ming could learn, and Bai Ming couldn't help but have some guesses.

"Report to Your Excellency Legion Commander, the daily generation of arcane in the institute is completely random."

"Does that mean that even the ninth-order arcane will appear?" Bai Ming hurriedly asked.

"Orders one to nine are completely random."

Hearing the adjutant's answer, Bai Ming instantly became messy. It turns out that this first arcane is just shit luck. If a high-level arcane is randomly found now, it will be useless for Bai Ming for the time being.

However, since Bai Ming's whole body has been transformed into super energy cells, it is basically equivalent to refining cosmic energy when eating and drinking. It's only a matter of time before the wizard ranks.

After testing the new skills, taking the elevator, Bai Ming went directly to the ninth floor. The ninth floor wasn't empty, but it was almost just a huge book.

The book was about the size of a table, and the first page had been turned. However, Bai Ming took a closer look and found that there was not a word.

At the moment when Bai Ming stretched out his hand to touch the book, a system prompt sounded.

"At present, the remaining skill upgrade times are one, please choose to upgrade the skill of Your Excellency Legion." Then two candidates appeared on the huge book.

Apprentice High Arcane Heat Ray. Upgradeable directions: 1. Increase attack strength by 50%. Second, the attack range has been increased by 50%. Three, the mana consumption is reduced by 30%.

Apprentice Advanced Arcane Mirror Reincarnation. Upgradeable Directions: 1. Reduced arcane mirror spawn time by 30%. Second, the arcane round mirror can reflect the strength of spells by 50%. Three, the Arcane Circle Mirror has been extended by 50 percent.

Bai Ming thought that upgrading the skill level was directly and rudely upgrading the first ring to the second ring. I didn't expect it to be this kind of improvement at all.

However, this kind of is more in line with Bai Ming's appetite, if all the three directions of the thermal energy ray are upgraded. The high-level arcane art of the apprentice of the heat ray is completely comparable to the two-ring arcane.

Bai Ming could already imagine the scene where he was like a machine gun constantly firing heat rays at his enemies.

The upgrade of the mirror return technique is just as powerful, but it is a little less interesting compared to the heat ray.

After thinking about it carefully, Bai Ming chose to increase the attack strength of the heat ray by fifty percent without hesitation.

As a result, the heat ray suddenly became Bai Ming's strongest attack method.

Bai Ming also planned to strengthen the remaining two directions of the heat energy ray in the next two enhancements.

Next is the tenth layer, and Bai Ming was stunned when he just stepped into the tenth layer. I saw that all the walls on the tenth floor, including the ceiling, were like a display screen. The scenery around the entire research institute is mapped.

In the middle of the tenth floor is a towering round platform, on which a crystal ball the size of a human head is lying quietly.

As soon as his right hand was on the crystal ball, Bai Ming understood the purpose of this thing.

To put it bluntly, this tenth layer is equivalent to the main control platform of the entire research institute.

Everything in the Arcane Institute can be controlled through this crystal ball. Including the setting of authority of the institute, the call of the weapon defense system, as well as real-time monitoring of ten kilometers in the vicinity of the institute.

Bai Ming immediately chose to set the ninety floors of the research institute to be accessible only to him, while the eighth floor required his consent to enter. As for the remaining seven floors, they serve as the range of activities of other legionnaires.

After figuring out all the uses of the Arcane Research Institute, Bai Ming naturally began his next plan.

The Earth Legion is finally about to descend on the demon plane for the first time. As for the candidate, Bai Ming already had a plan in his heart.
