Time passes.

For the wizard apprentice, the confrontation between the Nine Heads of Fury and the Shadow Thousand Eyes Academy once every ten years was as if a catastrophe was about to come every ten years, but for a demon hunter like Green, a real yàn might be decades, hundreds of years, and a mere ten years was too short.

Now, the Nine Heads of Fury and the Shadow Thousand Eyes Academy War have been fought six more times, that is, sixty years have passed.

The Nine Furious Academy still stubbornly persisted, and the source of magic power did not show any tendency to dry up.

With the support of the Wizarding Academy's large number of Philosopher's Stones and abundant tasks, the Academy's teaching work is also going very smoothly, and the strength of the wizard apprentices is still barely able to fight against the Shadow Thousand Eyes Academy in general.

The Seventh College War is just around the corner, and on this day, Green's Faces of Truth Phase IV engineering research has also made a breakthrough.

In front of the Green test bench, there is a black and white giant mosquito with wings 37 centimeters long.

The body of this black and white giant mosquito is divided into five parts: head, thorax, abdomen, wings and feet, of which the giant mosquito wings are each 18 centimeters, with transparent scales, the head, thorax and abdomen are 22 centimeters long, covered with black and white scales, and the head mouthparts are stinging and sucking, evolving into a slender beak to pierce the skin of other creatures and absorb blood.

However, the real secret of this black and white giant mosquito's alien perception turned out to be its six-legged and a pair of tentacles!

And its way of perception is to perceive living things...... Breathe.

Respiration refers to the process of gaseous substances and energy exchange between the body and the external environment, and the respiration of ordinary flesh and blood creatures includes three interrelated links.

First, pulmonary ventilation and pulmonary ventilation for external breathing.

Second, the transport of gases in the bloodstream.

3. Internal respiration, the exchange of gases between body tissues and blood.

The normal lung capacity of the average adult in the wizarding world is between 2,500 milliliters and 4,000 milliliters, while the alchemy wizard generally reaches more than 15,000 milliliters.

Biological breathing inhales into the body elemental energy, gaseous substances, that are beneficial to the body. At the same time, exhale out the waste that has been used by the human body.

These waste materials are the clues for the black and white giant mosquito to perceive biological traces, and it is also the reason why the stealth ability of the Wizard Grimm's appearance robe is ineffective in front of these black and white giant mosquitoes!

On the hexapods and tentacles of the black and white giant mosquito, high-powered microscope observation will find dense sensory tentacles, which can sense the breathing of nearby creatures according to the changes in the surrounding airflow rules, and then find the target of the prey.

In other words, Green only needs to study these perceptual tentacles thoroughly, and the fourth phase of the Truth Face project will naturally be able to proceed, and Green's Truth Face's ability to penetrate the light veil between appearance and truth will be taken to a higher level, and it will be one step closer to the epic witchcraft that Green once expected.

............

Seven days later.

The research on the giant mosquito has come to an end for the time being.

The rest will be up to Green, based on the findings. To improve the function of adding the face of truth, which will involve some knowledge of witchcraft rune transformation and magic array, it will take a lot of time to set up calculations.

So what to say at this time......

Green came to another real yàn room, this real yàn room was empty, only in the center was a huge vessel covered with energy conservation sealing witchcraft dense magic runes, this is the most common auxiliary real yàn equipment in the wizarding world, and even the ancient real yàn room that Green found in the secret realm of Hesuota has begun to use.

"Young Master, this Sacrificial Exchanger Void Creature is very interesting, and we can also become Sacrificial Exchangers in the future. To lure those beings of the foreign world to sacrifice their lives, to summon us to come to the past, quack, quack. ”

In this way, the ability of the sacrificial communicator is somewhat similar to the ability of the evil devil in biographical novels.

To achieve the other person's wish to seduce others. When the other party is full of vigilance, only leave clues to summon their own coming, and when the other party encounters some problems that cannot be solved temporarily but is extremely eager, or when they are in danger of life, they will finally think of themselves. And from then on to the abyss of depravity.

Green shook his head with a slight smile and did not respond.

Take out the Book of Truth, after Grimm silently recited the witchcraft incantation. A large number of wizard texts flew out of the book, and as the door of the forgotten world opened, dozens of sweaty hands pulled a void creature, gradually releasing a little bit from the door of the illusory world.

"Wizard, we have something to discuss, don't do this! sealing me is not good for you, my void energy is of no help to your physical life, what do you want from me, just say ......"

The void creatures that revealed the tip of the iceberg from the illusory world begged for Grimm while desperately struggling, trying to break free from the pull and seal of those sweaty little hands.

Decades of sealing the Forgotten World have really made this void creature terrified of the decay and loneliness of the Forgotten World.

What is the difference between this and death?

Grimm smiled at the face of truth, and under the gentle surface was Green's greedy excitement for the specimen's willingness to obediently take the initiative to cooperate.

"Knowledge! For wizards, knowledge is a truly priceless treasure, what knowledge can you give me?"

After a pause, Green added in a cold voice: "If you can't give me the knowledge that makes my heart flutter, then you, as a real specimen, are the source of my knowledge. ”

Xiao Ba smiled and added: "Quack, there is also the Void Treasure, any substance that can resist the power of the Void is a Void Treasure!"

The Void Creature heard the hope of leaving the Forgotten World, and immediately became excited.

"Knowledge?, respected wizard, I call myself a sacrificial wanderer, and you can call me that, so what kind of knowledge do you want?"

Nodding with a smile, Green said in a deep voice, "The way you sacrifice the trader's ability is the knowledge I want. ”

Without hesitation at all, this void creature slowly and patiently narrated the operation of his innate abilities, as if the humans of the wizarding world were talking about how to eat,, and pee.

It took two days for Green to figure out how this ability worked.

It's just that because Green doesn't have the ability to sense the time gap of the Void in a half-step time, he can't use it.

"Oh, the way the soul works is still like this? It is worthy of a void creature, and the eyes of the world are very different from the life of the material world. ”

Green nodded with satisfaction, as if he recognized the knowledge explanation of this void creature, and then said: "Tell me in detail about the material world you have traveled, it's okay, I still have a lot of time." ”

At this moment, the Void Creature began to explain its experience of traveling to sixteen worlds...... (To be continued......)
