Through Ai's memory, Zhang Sen gained a lot of valuable knowledge.

In particular, the design and philosophy of Abbas's eyeballs are not outdated even today.

The eyes are the windows to the soul.

Abbas believed that among the many organs of wizards, the eye was the best organ for releasing spiritual power, and even researched many spiritual spells to use with the eyeball.

Eye Modification, Eye Spell Implantation, Eye Fusion, Eye Material Replacement......

Zhang Sen is like a sponge, constantly absorbing Ai's experience, but Ai's experience is too huge, he only absorbs one-third of it before he feels dizzy, knowing that he is a little too big.

After all, his cultivation time is too short, and the gap between his spiritual power and Ai's spiritual power is huge, and his knowledge is less than 1/10,000th of Ai's, and he has to spend a lot of time to sort out this knowledge in one go, and it will take even longer to understand it thoroughly.

At this time, they landed on an inconspicuous small satellite, which orbited a huge planet, and Jeff directly made a hole, and everyone entered it one after another.

After Zhang Sen arranged the concealment formation, he immediately set about refining the Wizard's Eye.

He actually has quite a few wizarding eyes, but those wizarding eyes are not comparable to Ai's wizarding eyes.

Ai's Wizard's Eye is definitely the most advanced wizard's eye in the cultivation world at present, even tens of millions of years ahead of most wizards, and his research on the wizard's eye is beyond the reach of other wizards.

Since Zhang Sen has obtained this knowledge, he will naturally not waste it.

Wizard's Eye, most wizards have the ability to refine, and all they need is a variety of materials.

Ai was imprisoned in the underworld and had no materials to refine, but Zhang Sen carried a dimensional safe with him, so he didn't have to worry about the material problem at all.

Although Ai remembered the high-level wizard eye, he couldn't refine it for the time being, but the low-level wizard eye, he was more or less sure.

He prepares to refine a kind of wizard's eye in Ai's memory, which Ai named as Jet Eye.

The function of the jet eye is very simple, that is, to store a certain amount of mental power, and then use this mental power to generate pressure, so as to compress and spray air.

This is a typical strong wizard's eye, how much combat power the wizard's eye can exert is completely dependent on the user's injected spiritual power to decide, the stronger the spiritual power, the stronger the power.

Zhang Sen knew very well how many catties he had, so he didn't challenge the difficulty like the protagonist in it.

Besides, this jet eye is just his test of the waters, and it doesn't matter if he fails.

Although he had seen how powerful the Evil Eye had been in his heyday through Ai's memories, he didn't really want to become a second Evil Eye wizard.

He can absorb the knowledge of the Evil Eye Wizard and use the methods of the Evil Eye Wizard, but he will not be as persistent as Ai.

Time flies, and five days have passed in a blink of an eye.

Zhang Sen basically spent refining all kinds of wizard eyes during his time, and Jeff and the others realized that he might have mastered the knowledge of evil eye wizards.

Among them, the two brothers were envious, and even quietly asked Zhang Sen to exchange the knowledge of the evil eye wizard through trading, but unfortunately they have no long-term property now, and Zhang Sen didn't believe that they would keep their promise after they were powerful in the underworld, so they simply refused to trade.

Moreover, the value of the knowledge of the Evil Eye Wizard is definitely higher than that estimated by the two brothers, and the several wizard eyes that Zhang Sen has refined during this time are already quite extraordinary, and even one of them is the core secret method of the Evil Eye Wizard.

The so-called core secret method is the spell that supports the entire system.

For example, Zhang Sen's core secret method is actually the "Cosmic Brain Meditation Method", but the core secret method of the Evil Eye Wizard is not the meditation method, but the Eye of Reproduction secret technique!

The Eye of Reproduction is also a kind of wizard's eye, but this wizard's eye is very special, it will absorb the energy that is free from the world, and gradually reproduce itself.

Because the Wizard's Eye produced by the Eye of Reproduction is a blank Wizard's Eye, it is suitable for various transformations.

Why do Evil Eye Wizards have hundreds of billions of wizard eyes, in fact, this is the answer.

The Eye of Reproduction is actually similar to a special life form, Zhang Sen actually didn't really grasp the principle of the Eye of Reproduction, but he drew a gourd according to the scoop, according to the refining technique in Ai's memory, after a few failures, he completed an imitation under a highly similar operation.

It's a pity that he still wanted to create more Eyes of Reproduction later, but he failed N times in a row, and finally in order not to continue to waste resources, he stopped making Eyes of Reproduction.

The function of the Eye of Reproduction, in fact, in addition to self-splitting, has many functions, but basically they are all auxiliary functions, so I will not list them one by one here.

After Zhang Sen obtained the Eye of Reproduction, he created several kinds of Wizard Eyes in a row, including Ai's second core.

If Zhang Sen's core secret method is the "Cosmic Wisdom Brain Meditation Method", then the second core secret method must be the "Auxiliary Drive Cultivation Technique".

Ai's second core is still a wizard's eye, called the Eye of Monitor.

This eyeball can accept all the pictures transmitted back by the wizard's eye, and then turn it into information and feed it back to Zhang Sen's mind, no matter how many pictures can be transmitted perfectly, so that Zhang Sen can see the surface of the lake, which is not only orderly but also very convenient.

Without the Eye of Monitoring, it would be impossible for the Evil Eye Wizard to control so many Wizard Eyes, so this eye is also quite important, and it is a mainstay in Ai's combat system.

After possessing the two most basic but important eyes, Zhang Sen refined a part of the wizard's eyes with extremely strong concealment ability, and released them all as eyeliner.

In fact, with the trillion Demon Eye Emperor as a scout, it was completely superfluous for him to do so.

However, his biggest purpose in doing so was not to gather information, but to get used to the feeling of a large number of wizarding eyes as eyeliner.

A lot of the knowledge of the Evil Eye Wizard is extremely advanced, and it is impossible for him not to use it, and the most advanced knowledge of the Evil Eye Wizard is basically about the Evil Eye, and he will definitely use it in the future, although he will not be as persistent as the Evil Eye Wizard, but he will definitely not abandon it, after all, this is a very powerful and useful ability.

In the five days that Zhang Sen had been refining the Wizard's Eye, a lot had happened in the outside world.

First of all, the barbarian emperor destroyed the previous battlefield in a rage, and even exploded several planets in one go, and released a word that as long as Zhang Sen and the others dared to come out again, he would kill Zhang Sen and the others.

The second thing is that some unlucky contestants were caught by the Barbarian Emperor, and the Barbarian Emperor directly used these people to vent his anger, killed these contestants very cruelly, and nailed the corpses of these contestants to an iron plate, forming a line of words: "Coward, come out!" ”

His purpose in doing this is obvious, that is, he wants to kill Zhang Sen and others.

However, his approach aroused Zhang Sen's suspicions, after all, his behavior was too strange.

Whatever the death row inmates want to do, isn't it better to do it quickly?

They have been blocking the underworld for a while, could it be that the officials of the Eternal Kingdom have not reacted, and the efficiency is not so low.

Zhang Sen doesn't believe that they are not afraid of the eternal country, then the answer is obvious.

It is likely that the speed of time in the Dark Realm has been altered.

For example, in the dark world for a year, the outside world for a second.

Coupled with the fact that Alius secretly modified the live broadcast screen, the probability of the Eternal Kingdom being kept in the dark is quite high, even if the Eternal Kingdom is very advanced, it will take at least dozens of seconds to react, which is completely enough for the underworld.

Of course, this is just Zhang Sen's speculation, although he intuitively feels that the possibility is almost 80%, but whether it is right or wrong, he is not sure.

But for the time being, he can only assume this and prepare for the worst.

This assumption is not without its good side.

If his assumptions are true, then they will have more time to deal with death row inmates.

"It's not a way to go on like this, Daoyou Zhangsen, what are your plans?" Hai Erlonghu stood still for a few days, and he was very upset in his heart, and asked in front of everyone in the gap between Zhang Sen completing the experiment.

Zhang Sen shook his head and said: "There is no plan for the time being, the barbarian emperor is not a fool, if you want to kill him, you must find the most suitable time, and we still know too little about his information now, and we are mainly collecting information at present." ”

Before, the barbarian emperor shot angrily, completely using terrifying power to shake the space, and the planet collapsed in an instant.

But this is definitely not his real strength, just the tip of the iceberg.

Zhang Sen realized one thing when he saw him attacking, that is, the number of people was probably of little significance in front of the Barbarian Emperor.

If you want to kill the Barbarian Emperor, you need elites, not cannon fodder.

At present, as long as he and Jeff can be called elites on their side, Li Zhenping is still a little behind, and the two brothers are completely minions.

"To tell you the truth, Daoyou Zhang Sen, it's not that I don't believe you, but now the Barbarian Emperor is definitely the weakest time, if the other party's backup rushes over, I'm afraid it will be too late for us to make another move." Hai Erlonghu said immediately.

Zhang Sen nodded and said: "I have also thought about this, now that the barbarian emperor's right-hand man has lost two of his three hands, and the backup evil eye wizard Ai has also been cleared, it is indeed the weakest time, but ...... No matter how weak he is, he is still a barbarian, can't you see how powerful he is when he attacks, if you can block that punch, then I can consider making a move. ”

"And when are we going to wait?" Hai Er Longsen knew that Hai Er Longhu couldn't get off the stage, so he asked.

Zhang Sen said lightly: "Wait until I'm sure." ”

"Brother, don't you want to completely digest the knowledge of the Evil Eye Wizard before you do it?" Jeff stepped forward and grabbed Zhang Sen's shoulders and asked in a low voice.

Zhang Sen shook his head and said: "It will be impossible for the Evil Eye Wizard to fully grasp the knowledge for a while and a half, and it is impossible to do it in a short period of time when he is thoroughly thorough, I am waiting for a time, a time to do it." ”

Unfortunately, the Evil Eye Wizard knew very little information, far less than he had estimated.

However, through the information that the evil eye wizard knew, he had actually guessed a lot of content, and at the same time vaguely grasped the movement of the death row prisoner.
