Follow the mysterious Kane out of the pressure confrontation training room, along the way, Kane didn't say a word, Duan Lie wondered what the purpose of this red-bearded lord was, until he entered the battle tower, Kane walked to an inconspicuous small door in the innermost part to reveal a winding staircase, he realized that there was another unknown secret room under the battle tower.

It's definitely a secret room, and it's the kind of secret room that is protected.

After entering the small door, the first thing Duan Lie saw was a spiral staircase that winded downward, the buttress of the staircase was engraved with strict guard inscriptions, the steps had dense hollow stone slabs, and the walls were also engraved with complex solid inscriptions, which were even tighter than the protection measures of the ten-story battle tower above. And there is also an intricate array of inscriptions on the steps of every ten staircases.

This inscription array is much more terrifying, others may not know the meaning of the inscription array, but he knows it very well.

An inscription array is an array of multiple inscriptions arranged in order, and this array serves two purposes.

Normally, the inscription array involves several inscription effects, when they form a certain scale, they will be triggered to produce a kind of power, the biggest effect of this power is that it can use a small amount of fighting energy to exert a powerful combat skill effect, most of which are used to make holy weapons, artifacts and above level of defensive equipment are often used. So in terms of difficulty, it is much more difficult than carving an inscription.

As far as Duan Lie knew, the Inscription Array was only capable of being arranged at the Grandmaster level, and each Inscription Array was like a password with an independent and singular characteristic.

Unless it was the Grandmaster himself who arranged the Inscription Array, or a Grandmaster who was more senior than him, no one could understand the characteristics of an Inscription Array.

The second function of the inscription array is to protect a special space, the inscription array can be used as a password-like existence, if an inscription array is arranged in a room, it means that only the person who arranges the inscription array can enter, otherwise if you break in rashly, you will definitely be attacked by the inscription array, and you will be seriously injured or killed.

The terrifying array of inscriptions, Duan Lie really couldn't be clearer, so it was not enough to see that the spiral staircase was arranged with an indefensible inscription, but also an inscription array was set up every ten steps, it is conceivable that the ground of the battle tower is very likely to be some kind of forbidden area, and it is even more likely to protect something.

Of course, these inscription arrays in front of him were nothing in Duan Lie's eyes, if he wanted to decipher these inscription arrays, it would take him minutes of work, so it can be seen that these inscription arrays should be in the hands of an inscription grandmaster, but he is not needed yet.

Kane was obviously familiar with the inscription array, and every time he walked the ninth level, Kane was very careful to let Duan Lie stop, and then used his fighting spirit to arrange the inscription array of the steps under his feet, and explained to Duan Lie while arranging: "This is the inscription array, you have to be careful, follow me, don't cross me, otherwise it will be very troublesome." ”

Kane didn't know that there was a supreme inscription master standing beside him at the moment, and if he knew it, he would be able to go to the land by now.

Skillfully unlocking the code of the inscription array, the two of them walked all the way to the lowest level of the battle tower.

This was a total of as many as ten sets of inscription arrays, each of which was different, and Duan Lie was also a little surprised, after all, until now, he had not heard of any master in the Heavenly Wind Empire who could arrange ten groups of inscription arrays.

Coming to the lowest level of the battle tower, there is a small space, and directly in front of it is a secret door protected by a set of inscription arrays......

Open, walk in......

Another secret door......

Seeing this, Duan Lie was already frowning, it was obvious that with such strict protection, there must be something particularly important in it that needed to be protected, what did this Kane want to take to see himself?

With a hint of doubt, they passed through a total of three secret doors guarded by the inscription array, and the two of them came to a spacious room with an area of more than one hundred square meters.

The room was empty, only on the opposite wall, there was a Dou Qi force field halo engraved with two sun, moon and stars, Duan Lie was slightly stunned at first, and then said in surprise: "Is this a Dou Qi force field?"

"To be precise, this should be a kind of spirit fighting technique. Kane nodded and explained, "That's what I brought you here for, and now you should know why the academy built the tower here." ”

Duan Lie suddenly realized, no wonder Kane had been mysterious, and what was being protected under the Dare Battle Tower was a kind of spirit fighting technique.

But Duan Lie was a little puzzled, the Dou Qi Force Field was a special ability that appeared on the fighter's body, formed through the Dou Qi and soul perception, why the aura of the Dou Qi Force Field appeared on the wall, and it was still vivid.

The fighting force field in front of him is indeed vivid, there are only six lighting crystals in the room, if you rely on the strength of the lighting crystals, you can't illuminate the room as bright as day. But it is precisely because of the aura of the Douqi Force Field, that the red light emits out, which makes the room as clear as a searchlight, and more importantly, although the Douqi Force Field is on the wall, it rotates like a screen over and over again.

At this time, Kane said: "You can see it clearly, this is the only kind of spirit fighting technique in the War Spirit Academy, because no one in the academy from His Excellency Di Luo to the students has comprehended the fighting energy field for two hundred years, so no one has been able to learn this kind of spirit fighting technique." But today there is finally a genius in the academy, and I think only you can decipher the true meaning of this Douqi force field. ”

Speaking of this, Kane couldn't help but feel a trace of pride, in the decades he had been teaching, he had finally met a genius who could arrange the fighting force field and have a self-fighting system, and Duan Lie was this genius who could become the pride of the academy.

Duan Lie understood that Kane wanted to allow himself to cultivate the Dou Qi Force Field and comprehend the Spirit Fighting Technique.

For this, Duan Lie is quite grateful to Kane.

He knew very well that if a fighter relied on his own strength to slowly figure out and arrange the Dou Qi force field after he had a fighting force field and wanted to comprehend a spirit fighting technique through this, it would be very difficult, and the Wuji God of War once said that a person who created a spirit fighting technique might not be able to complete it in a lifetime, and ten or twenty years is too short.

But if someone presents the Spirit Fighting Technique they have created in the form of a Fighting Qi Force Field, and asks another person who has just had a Fighting Qi Force Field to learn it, it will be much simpler.

You must know that the Fighting Qi Force Field can not only be kept in the body, but also can be controlled and presented by the consciousness of the fighter, so under normal circumstances, a fighter who has a Fighting Qi Force Field or even a Spirit Fighting Technique, they do not easily formalize their Fighting Qi Force Field, which is too easy to be learned.

And on this wall, it is obvious that someone has specially left it for future generations to study, the pattern of the fighting force field has been determined, and the order of the arrangement is quite perfect, but Duan Lie still doesn't understand it, to be precise, it's doubtful.

The Dou Qi Force Field is a fighter's biggest secret, how could someone hastily share their cultivation experience with others, even if they intentionally taught it, they wouldn't be so low-level, just make a simple void inscription, create a unique and typical distorted space, and solidify the Dou Qi Force Field with Dou Qi?

Duan Lie didn't understand, but he didn't think too much about it, maybe there were really people who wanted to pass on their experience selflessly.

Thinking like this, he listened to Kane say: "Duan Lie, from today onwards, you will comprehend the Spirit Fighting Technique here, I will come early tomorrow morning to pick you up and take you to the pressure confrontation training room to continue your training, I will disrupt the inscription array outside again, when I don't come, you must not go out easily, it will be very dangerous." ”

"Thank you, Lord Kane. Duan Lie turned around and thanked Kane very sincerely.

Kane smiled and waved his hand, and said, "Don't worry, I want you to promise me a condition." ”

"On what terms?"

Kane smiled: "This spirit fighting technique is the biggest secret of the academy, even the elders in the academy have no right to know, I give it to you now, I hope you can protect the War Spirit Academy in the next thirty years." ”

"Thirty years?" Duan Lie understood, there was really no free lunch in the world, Kan Ken handed over a spirit fighting technique to himself because he took a fancy to his talent, and if he learned the spirit fighting technique, he would definitely become a top master in the next ten or twenty years, and at this time, he would have to throw a peach and hug Li to the academy.

Although Kane's approach has a certain nature of interoperability, Duan Lie is still very grateful to Kane, after all, this kind of spirit fighting technique is not for himself, if he takes it out, it is not something that money can measure, even if it is an auction, he can't buy it without an absolute sky-high price. And now, he only needs to promise Kane one condition to learn this spirit fighting technique, which is very cost-effective.

So Duan Lie nodded without thinking about it, and said sincerely: "Don't worry, Your Excellency Kane, I will always remember the kindness of the academy." ”

Both of them are extremely shrewd people, and some words don't need to be said too clearly is enough, Kane nodded, and then left satisfied.

Satisfied, Kane is quite satisfied now, others may not know, but he understands quite well, a genius who can comprehend the fighting force field at the age of twenty, if he gets another kind of spirit fighting technique, he will be the top master of the entire continent in the future, and now he will attract an absolutely powerful backer for the academy in the future.

Kane left, Duan Lie calmed down and looked at the Dou Qi Force Field on the wall, the way to arrange the Dou Qi Force Field was very simple, just need to summon your own Dou Qi Force Field, and re-plan and arrange it according to a specific combination.

But in a row, Duan Lie found a problem
