The content of the letter was that Meng Tian was going to discuss the matter of the Overlord Knife with Tang Song, and he hoped that Tang Song would calm down and not send the Overlord Knife to the auction house, and that their Command Mansion was willing to pay a high price to buy the Overlord Knife back. The condition is that Tang and Song cannot publicize this matter to the outside world.

And the letter also said that Tang Song wanted to go to the appointment alone, not to alarm more people, and to save a little face for the Commander's Mansion. In the letter, Meng Tian put his position very low, as if he was afraid that this matter would be known to others and have a negative impact on their Commander's Mansion.

In order to dispel Tang Song's suspicions, Meng Tian even offered to let Tang Song think about it for two days before giving him an answer.

Tang Song spit out vigorously, turning the letter into ashes, and a faint smile appeared on the corner of his mouth.

Walking out of the palace, when he saw him, everyone saluted him one after another, Tang Song nodded, went all the way out, and came to the big lawn outside. After determining the location, he took out some Yuan Crystal and put it on the ground.

It is not placed casually, but according to the correct orientation of the formation. Tang and Song Dynasty bought a first-level trapped array jade slip in Wanbaozhai, and the method of arranging the array was arranged according to the above. The most difficult part of arranging the formation is not how to arrange the formation, in fact, how to arrange it according to the cheats can be arranged by anyone, the difficult thing is to activate the formation.

After the formation is arranged, it can only be called a real formation if it is activated, and ninety percent of the people are blocked out of this layer.

Of course, if you want to become a smart array mage, it is not enough to read according to the cheats book, you have to understand by yourself, how to turn the dead knowledge in the book into your own living knowledge, which is the quality that a smart array mage must have.

For example, a trapped formation, why is it at the mercy of a certain direction, and then it can be used to trap people after activation. In terms of things, no matter how many levels of formations, their origins are the same, only if the basic principles are thoroughly understood, then when the cultivation is reached, the formation arrangement and activation will be a matter of course.

Therefore, basic knowledge is the most important thing. Often many formation mages put the cart before the horse, thinking that only the more brilliant the formation cheats can cultivate the more intelligent formation mages. In fact, this understanding is wrong, as long as the basic principles of the formation are truly understood and understood, then the way of the formation seems to you to be just moving a few stones.

For a formation mage, how much you understand the basic principles directly affects what level of formation mage you can become in the future.

Of course, for Tang and Song Dynasty, a rookie in the formation, it is the most practical to test the lowest formation first. Now what he wants to arrange and activate is a first-level trapped formation.

After placing the Yuan Crystal according to the direction introduced above in the jade slip, the next step is to arrange the most difficult level of the formation, activate the formation. It's just a small level 1 trap, so it's the easiest to activate. Like those large-scale mountain gate guardian formations, city guardian formations, and even large-scale Juyuan formations, the scope involved is too large, so not only is it a huge project to arrange, but it is also a big problem to activate.

Therefore, sects like those below the fifth rank have no ability to arrange the mountain gate formation at all, it is too expensive, even if they can afford to provide materials, they can't afford to hire a formation mage to set up a formation for them.

The arrangement of the formation involves the framework and principle of the formation, and the activation of the formation involves the balance of the strength of the formation. Whether a formation can be successfully arranged depends on whether the various forces in the formation can reach a state of balance when the formation is activated.

It can be said that when the materials of the formation are arranged, there is already an invisible connection between them, and at this time, activating the formation, with a little attention, will make the power imbalance between these materials, and the final result will be an explosion.

Tang Song cautiously came to the place where the array eye was, and the other formations of the first-level trapped array could all use low-grade yuan crystals, but the array eyes needed to be arranged with medium-grade yuan crystals. This is also the basic formation, and the higher-grade formations all require special formation materials to be arranged.

Tang Song put his hand on the Yuan Crystal of the Array Eye, and then carefully input the energy into it, his brain was highly concentrated, and his spiritual sense spread out, stretching out like tentacles, and the situation of the entire formation was imprinted in his mind, just like the capillary veins centered on the Array Eye.

And the energy of the Tang and Song dynasties, like blood, flows along these capillaries.

Of course, the thickness of these capillaries is different, so the amount of energy in each channel must be controlled, which requires the caster to be multi-purpose. Especially when you practice for the first time, you are most likely to have accidents.

Bang!

The Yuan Crystals all around exploded, ruthlessly announcing the failure of Tang and Song's first formation.

Tang Song took out the Yuan Crystal again, arranged it again, and then injected energy to activate the formation. The degree of activation for the first time was less than one-tenth of the explosion, this time, Tang Song was doubly careful, his energy was concentrated again, he closed his eyes, spread out his spiritual sense, imprinted all the formation veins in his mind, and finally carefully input the energy into it.

Push forward bit by bit.

"Well, it's smaller here, wow, why is it so small ...... here!" Tang Song pushed his energy forward, his mouth shattered. There are too many paths, and the thickness is different, if you don't pay attention to it, it's the same as the result just now, explosion!

Bang!

Tang Song's forehead was covered with sweat, and just when he wanted to relax, the input energy was already chaotic, and finally exploded.

Tang Song sat paralyzed on the ground, panting, Tai Nima was tired, this thing was simply not done by people. "That's not right, if every formation has to be like this, how should those large formations be done?

A small first-level trapped formation, the simplest formation in the world, is so difficult. And how many thousands of miles are covered by those mountain protection arrays, how to activate the formation?

If it's like what he is now, it's completely unachievable.

The range covered by his trapped array is only a hundred meters in radius, imagine those large arrays covering thousands of miles, if they really want to activate like this, I'm afraid they will only end up being exhausted.

I picked up the basic analysis of the formation again, and looked through the jade slip of the trapped formation again, but I was stunned that I didn't find a solution.

Tang Song suddenly remembered the innate trapped array he had obtained in the Qingqian Secret Realm, took it out, and then arranged it on the lawn, and finally injected the true qi of the two instruments, and then, the formation was naturally activated.

Tang Song was a little dumbfounded, what the hell is going on? This innate formation is so easy to start, but this acquired formation is so troublesome, what is the difference?
