The Death Desert has a special prohibition, which will suppress abilities such as flight teleportation, and the more you go to the center of the desert, the more powerful the prohibition becomes, so if the practitioner wants to cross the Death Desert to the ancient battlefield, it will take an average of more than three months to waste.

This is not that the Chaos Demon King has banned it, but the result of the operation of the world consciousness, the purpose is to make this Death Desert a huge buffer zone, the ancient battlefield has lost control, and this huge Death Desert has become a frontline position, so it will evolve into a buffer zone through rule operation.

As for why there is a rule to prohibit the actions of the trialists, this is also a helpless move, because unilaterally banning chaos creatures can easily find loopholes and make this prohibition a decoration.

Every day is slightly bright, I will pack up and continue on the road, and when night falls, I will put down the enchantment formation and rest in place, and from time to time there will be encounters with the invading monster groups, although it is not much dangerous, but it is still very hard, and the number of encounters is becoming more and more frequent.

Of course, the most excited is Athena, she can finally participate in the battle again, she has been lectured by Li Yunfei every day for a period of time, and finally learned a lot to behave, and she is no longer a brainless rush on the battlefield.

It's been a month since I entered the Death Desert, and I have entered the core area where the ban is the most powerful, and all flight abilities here are banned, even if I put a rocket backpack with a thrust of ten tons, I still can't support my body of dozens of kilograms, the ban is so powerful, what physical rules are a fart in front of it.

……

Another encounter ended, annihilating a group of scorching demons from afar from the ancient battlefield, there were tens of thousands of heads, and a lot of magic crystals were found in the equipment gold coins left behind, of course, these magic crystals were collected by Li Yunfei, this kind of thing Li Yunfei did not refuse.

"Brother Yunfei, why can this scorching flame demon burst out of magic crystals?" Miliah asked all the things that everyone wanted to ask.

"It should be caused by the power of chaos invading the monster's body in large numbers, just like the monster in the Lost Lands."

"But the Desert of Death is not a lost place!" Linnie answered.

"Although this place has not yet become a lost place, there has been a large number of invasions of the power of chaos, so I think you have also felt the fluctuations of the power of chaos, right?"

“…… So this desert of death is about to become a lost place? Milia was a little anxious, if this Desert of Death was reduced to a lost place, then the Endless Sea would bear the brunt, and the Paradise Island would be in the Endless Sea......

"If you don't take care of him, according to the current state of affairs, it won't take ten years to lose here, of course, as long as you repair the ancient formation of the ancient battlefield, everything will not be a problem."

"No wonder Brother Yunfei is so anxious to go to the ancient battlefield to repair the space-time barrier, but unfortunately he left in too much hurry, and he didn't have time to gather the masters to accompany him, and he didn't know if this mission could be successfully completed." Miliah said to herself.

"Didn't the teacher say it, if you are in a hurry, a large number of master peers will definitely attract the attention of the Chaos Demon King, and then it will become a large-scale tug-of-war, or a team like ours will sneak over, so that it will not attract attention, and the possibility of success is greater." Athena re-said Li Yunfei.

After distributing the loot, there is no rush to hit the road, and there is a possibility of encountering a huge group of monsters at any time in this dead desert, so it is safer to keep your body in the best condition.

"Okay, let's go back and rest, let's continue on the road when we're rested!" Saying that, Li Yunfei directly took out the laboratory, and took advantage of the rest time to deduce the repair method of the ancient array on the ancient battlefield, although the large array has been abandoned, but there are still records on the information of the angel clan, there is a rough structural diagram, you can deduce it first, and you can speed up the repair when the time comes.

When everyone was busy with themselves, only Athena seemed to be a little idle, ready to play with the sword.

"Athena, you come with me to deduce the big array!" Li Yunfei greeted.

"Oh, got it!" Hearing Li Yunfei's greeting, Athena could only obediently follow up with the laboratory.

Of course, it was said that it was to deduce the big array together, but in fact, it was to watch Li Yunfei where Li Yunfei was constantly debugging, and she couldn't help at all, and there were even many places that she couldn't understand at all, but for the sake of face, she decided not to pretend to understand.

Athena didn't know how to pretend to understand on the side, of course Li Yunfei could see it, and he didn't break it, he still saved her a little face, but in the process of deduction, she muttered to herself why she did it, what effect would it have if she did it, Athena tried to memorize it on the side, although the learning efficiency was extremely low, but it could only be like this.

If you can stay in this world for many years, you can teach some carefully, but now there may be changes and leave at any time, and there is no time to slowly impart knowledge, and the first goal now is of course to find a way to complete the repair of the ancient battlefield's large array, and then complete that ultimate task as much as possible.

As for Athena, she can learn as much as she can, anyway, the knowledge of the basic Mithril circuit has been taught to her, and the master has led her into the door to practice personally, and she can be regarded as fulfilling this responsibility as a teacher.

……

After more than an hour of continuous deduction and refinement, I deduced the general maintenance plan from beginning to end, and when I turned my head, I saw that Athens had a problematic expression.

"Athena-san, what's the problem?" Li Yunfei took the initiative to ask, ready to do his duty as a teacher to solve doubts

"I said the teacher, don't be angry."

"Don't be angry, just ask!"

"I've completely mastered the Genshin Strike that the teacher taught, can you teach me a new skill!" Athena said expectantly.

Li Yunfei really didn't expect Athena to master the Yuan Shen Strike in just a few days, you must know that it took you more than half a year to practice this skill, is the gap in this skill too big? If she follows this progress, maybe by the time she reaches the Ancient Battlefield, she may really be able to master the Mixed Element Strike. A hybrid that combines the power of the god of war will increase the power of one hit several times, so when dealing with super bosses, it can really help output a lot of damage......

"Didn't the teacher say that he wouldn't be angry, why don't you ignore others!"

"You're a ...... Forget it, I'll teach you another skill, or this is just an upgraded version of the Yuan Shen Strike, called the Mixed Yuan Strike, which can stack the power of the God of War that you master, and the power can be increased by 10 times......"

Before Li Yunfei finished speaking, Athena suddenly pounced on her body and kissed her hard, she was really excited and a little carried away.

"Let go, you prosperous glory armor, panic!"

"Oh, then I'll take off my armor first!"

"Take it off, take this to understand it well, whether you can master it depends on your own understanding." He took out a jade plaque and threw it to Athena.

The jade plate depicts the energy control mode of the mixed element strike, which is of course not depicted in the form of words, but directly printed on the jade plate in the form of consciousness information, and it is really not possible to read the means inside without strong spiritual power.

"Thank you, teacher, I will definitely study hard, goodbye, teacher!" took the jade plaque and ran out of the laboratory excitedly, excited like a child.
