There are so many types of formations that almost no one can say exactly how many there are. But it can be broadly divided into four categories: support, defense, attack, and illusion. The most varied of these is the support category, followed by the illusion category, and finally defense and attack.

For monks, the most frequently used formation is also the auxiliary formation. Whether it is ordinary cultivation or life, it is inseparable from auxiliary formations, let alone the time to fight against the enemy.

If you want to cultivate faster and easier, you need a formation like the Gathering Yuan Array, if you want to move quickly, you need a blessing like the Shenxing Array, and if you need better recovery ability when fighting, you also need an auxiliary formation.

Therefore, the auxiliary formation is the formation with the most types and the easiest to engrave.

Of course, Bao Zheng also understands that the formation studied by Zhou Yan and the two ghosts is currently mainly auxiliary class, because this formation is the mildest and easiest to implement. But even so, once successful, it is a feat against the sky.

Imagine that a revenant soul is engraved with a Gathering Yuan Array, and the cultivation speed can be turned up several levels again on the basis of the previous one, and even because this Gathering Yuan Array is equivalent to improving the talent in the soul, the outside world can still use another Gathering Yuan Array, so wouldn't it be exponential to increase the cultivation speed under the superposition of the two phases?!

Not to mention that after success, continue to study other types of formations, attack, defense, if this can become a talent, how terrifying is it? Even later, a revenant soul can be engraved with many formations on the soul, and each of them can become a demon-like existence?

It was not only Bao Zheng who thought of this, but also Wang Tianyun, the white tiger tooth general. As the first underworld boss who believes that there is a certain possibility of Zhou Yan's two ghosts' research, and at the same time is in charge of the key institution of the Yin Barracks, once the research is successful, the benefits will be the greatest.

The reason why these two living treasures were pushed into the hands of the ghost ya, instead of grabbing or reminding Ding Chunqiu and Zhong Mei by himself, was because he was considering the current status of the Yin Barracks.

The research institute and the weapon workshop were originally regarded by many souls as close institutions of the Yin Barracks, and were even regarded as one in many cases. And before, there was still a big guy like Ghost Ya standing on the side of the Yin Barracks, so as not to show how conspicuous the Yin Barracks was. It's not so good now. A storm that swept through the entire Daoless Underworld pushed the Yin Barracks to the cusp.

The ghost country is in charge, the ghost judge is both in prison, and the rest of the prefecture institutions are similar, only the Yin military camp is fine, which is a good thing and a bad thing. Because Wang Tianyun understands that the end of a single family is often not beautiful, especially now that Yan Jun's mind is a little harsh, it makes him feel a little uneasy. Therefore, a similar organization is needed to stand up and share the pressure of the Yin Barracks.

And the ghost ya, which is undoubtedly the only and best choice for the Yin barracks. Because Bao Zheng is very smart and able to accept new ideas and new things, he also urgently needs credit to redeem his trust in Yan Jun's heart.

The 40,000 recruits have completed a series of field training, and they are now stationed 10 miles outside the camp to ask to return to the camp. ”

The voice of the herald interrupted Wang Tianyun's thoughts, smiled, put down the performance of Zhou Yan's two goods after the ghost came out, adjusted it slightly, and immediately put his mind on the forty thousand recruits.

This is the power of the expansion of the Yin Barracks promised by Yan Jun before leaving. All of them are heroic spirits, and they are all born underworld warriors. And they are not really "junior brothers", in the yang world, they have been gathered by the soul gathering envoys early to start training, and the commanders of the four legions have always been in charge of guidance. Therefore, the quality of these heroic spirits is the highest.

Walking outside the tent, Wang Tianyun waved his hand, the gate of the camp opened, the horn was sounded, and ten miles away, there was the sound of drums, and one by one figures began to slowly appear in the field of vision.

"General, you see that this field training has also been completed, and I have been to see it, and they are all good men, so I don't have to choose. Why don't we start the assignment when they return to the camp?" Zhang Fei slipped to Wang Tianyun's side at some point, and said in a whisper with a hippie smile on his face.

"What's the matter, are you worried that your share will be snatched away?" Wang Tianyun has long been accustomed to the style of this corps commander, he looks very arrogant and rude, but in fact he is as careful as a hair, has all the qualities that a corps commander should have, and is quite good. Moreover, this Captain Zhang's cultivation talent is also terrifying, and he has actually come from behind to cultivate to the middle stage of the Ghost King, which is no longer weak. But this mouth is as broken as ever.

"You also know what kind of goods the other three corps commanders you have accepted are, they are really shameless and skinless, and they are simply outrageous! I Zhang Fei is not as shameless as them, so I can only ask the general to take care of one or two, lest my third legion suffer a loss." Zhang Fei didn't blink when he said this, and he didn't know that his second brother Guan Yu was also beaten by him with a sentence of "no face and no skin". For the sake of these recruits, Zhang Fei prepared to deny his six relatives this time.

"Oh, you're the thinnest of your skin, aren't you? Okay, tell me how much you want to replenish your Third Legion?"

While poking his hands, Zhang Fei said with a smile: "I don't take advantage of anything, you can give six thousand soldiers, and the remaining four thousand will be all auxiliary troops." You see......"

"Dream! This time, there are only 4,000 auxiliary soldiers among the 40,000 recruits, and you don't even plan to leave it to the other legions? Commander Zhang, I see, your skin is the thickest!" Wang Tianyun directly denied. This Zhang Fei, the lion opened his mouth.

Zhang Fei was not annoyed, and continued to pester: "General, I didn't think it through, otherwise, if four thousand doesn't work, three thousand, or two thousand!"

"Stop! There are only 1,000 auxiliaries per corps, and you don't want more! Okay, get out of here now!"

They all want auxiliaries, it's not that they look down on the soldiers, but in the continuous actual combat drills and confrontations with the blood ghosts, the strength of the auxiliaries is discovered little by little, which is useful and extremely critical.

A single auxiliary soldier can bless and rescue five to ten soldiers, and the combat power and sustained ability of the soldiers can be increased by five to sixty percent! Even as long as they are not seriously injured, they can be rescued and returned to the battle formation in just a few moments. How can this role not be taken seriously?

But there were too few auxiliary soldiers, which made Zhang Fei run facelessly to prepare to bewitch Wang Tianyun.

"Get out of here, General, don't you really think about my suggestion? Oh, don't fight, don't fight......"

Watching Zhang Fei run away quickly with his head in his hands, Wang Tianyun also smiled, this Zhang Fei is also a living treasure. However, this time the troops were increased, and Wang Tianyun also felt that there were still fewer auxiliary soldiers. The main thing was that he underestimated the role of the auxiliary soldiers before, and he cultivated too little on his own to cause the current dilemma.

"General, the recruits have entered the camp and are now gathering at the school grounds, please show the general!"

"Tell all the Legion Commanders to go to the school immediately, I have something important to announce!"
