Back in his room, Yi Xuan took stock of the previous experience of fighting with the Demon Gate Jin Dan Xin Mo, and with the blessing of Xiao Zhong's Heaven and Earth Vitality, he already had the capital to confront and even defeat Brother Jindan, but what he lacked was that the spiritual power of himself and his colleagues was far less mellow and profound than that of Brother Jindan, so he would fall short. However, it is obviously impossible to greatly improve everyone's spiritual power in the short term, so they can only start from the battle formation.

At present, the several battle formations mastered are stronger than defensive, suitable for rushing and killing on the battlefield, and now it is necessary to find a way to completely focus on defense and use all the remaining spiritual power to support the Zhongyan Sword Technique, which will definitely improve the maintenance time of the Sword Technique and greatly increase the ability to confront the Jindan Monk.

Thinking of this, Yi Xuan couldn't hold back the throbbing in his heart, and found Liang Tian again to explain his thoughts. Liang Tian is an old man in the army, he knows the station very well, thinking about it, he said to Yi Xuan: "Shi Chang, I remember that there was such a battle formation a long time ago, it seems to be called the Seven Star Tortoise Shell Array, which is just suitable for the training of seven monks, each monk holds a huge shield to protect the body tightly, and the seven people are arrayed according to the Big Dipper, no matter who receives an attack, the attack can be dispersed to everyone to bear together, it is definitely the best in the defensive battle array." But this formation is only defending, not attacking, and has long been eliminated by the army, if it weren't for the chief today, I would have forgotten about this formation!"

Yi Xuan slapped his thigh: "That's it." Hurry up and accompany me to the quartermaster department to find the formation map of this formation, we will step up the drill, and the drill of this formation will be proficient as soon as possible, I will be of great use!"

Liang Tian was very embarrassed and said: "Shi Chang, you should think about it again! It's not that I don't want to go, but this battle array had another name called the Ten Thousand Year Tortoise Formation back then, and the monks who used this array would be laughed at as greedy for life and afraid of death, and they would never be able to raise their heads again!"

"What are you paying attention to these trivial things? Think about it, the swordsmanship we used to deal with the Demon Gate Jindan last time combined with this seven-star tortoiseshell array, can we be both offensive and defensive, even if we face the Jindan monk again, we won't be as embarrassed as last time!"

Liang Tian's eyes lit up after hearing this, and he agreed loudly: "Shi Chang, how did you come up with this idea, it's really wonderful! I'll accompany you to find the battle formation diagram, so that others can discuss it, as long as you casually experience a big war, keep it and let everyone shut up!"

The two of them hurried to the quartermaster's office, and without waiting to speak, the quartermaster who had just received Yi Xuan to distribute the spirit stone pill saw Yi Xuan go and returned, thinking that he was making trouble with him because of the material exploitation, and hurriedly pushed the matter away: "Chief Wenshi, the spirit stones and pills you want to receive are counted in person, and the number is also explained by the elder himself, don't look for me if you have any dissatisfaction, I will act according to the order!"

Liang Tian glanced at him: "Lao Zhang, I and Shi Chang are looking for you, not for this dirty matter, some spirit stones can't be in the eyes of my family!"

Lao Zhang patted his chest exaggeratedly: "But it frightens me, just now there are already two elders who have come to question me why there is a shortage of spirit stones and pills, and I can't disobey this order, and I almost beat me up!

"We want the formation map of the seven-star tortoiseshell array, I know you must still have it here, hurry up and find it for me!"

Lao Zhang laughed out loud: "Chief Wenshi, don't blame Lao Zhang for not reminding you, although this seven-star tortoiseshell array is good at guarding, its reputation is not very good! Lao Liang, you are an old man in the army, why don't you remind you that you are long, when the time comes, will you have a smile on your face?"

Liang Tian blushed and said: "Don't worry about so much, these are already known by the elders of my family, we have our own clever plan, we don't need you to worry about this idleness, quickly find it for me, we have to rush to rehearse the formation diagram!"

Lao Zhang was so shocked that he stammered, and there was no reaction for a long time, and Yi Xuan also urged: "Lao Zhang, I already know that this battle formation is easy to be criticized, but I am really useful, you can give it to us quickly, there is labor!"

Lao Zhang sighed while picking and choosing among several storage bags, and said while looking for it: "Since you all talked about this, I will find it for you, anyway, this tortoiseshell formation is also an open battle formation in the army, and any commander can ask for it." But...... Ahem, what am I talking about!I've found it, I'll give it to you!" As he spoke, he handed Yi Xuan the jade talisman that burned the battle array diagram.

On the way back to the wooden house, Liang Tianyou, who had already been persuaded by Yi Xuan, had some gains and losses: "What's the chief, you also heard how that old Zhang arranged this tortoiseshell formation, are you really not afraid of other people's shameful laughter at all?"

Yi Xuan smiled slightly: "Do you think that I want to challenge the Demon Gate Jin Dan again in order to show off and make military achievements! Don't forget, Ji Shi Changke is still waiting for us in the medical hall, if we don't have the ability to fight Jin Dan, how can we heal his injuries!"

Liang Tian suddenly realized, and said convincingly: "Shi Chang, just say this to you, Lao Liang, I will let you out, and the brothers will persuade them by me, even if we are pointed at our noses at the station and scolded us as turtles with shrunken heads, I don't care!"

Yi Xuan nodded and said, "It's good that you can understand!" But the healing matter is only known to you and me, and you don't have to tell them, so it won't be good to save people a lot of chatter, and it will not be good to spread the word!"

Back at the residence, Liang Tian shouted loudly and shouted out all the people, and ordered everyone to start practicing the seven-star tortoiseshell array, Song Kaifeng and Gong Liang also heard of the notoriety of this battle formation, and didn't want Liang Tian to refute everyone's unanimous opposition without saying anything, and not give everyone any chance to refute.

Yi Xuan looked funny on the side, but he forced himself to pretend to have a serious face, and everyone was helpless, so they had to choose a position to stand according to the formation diagram, and were about to practice, when Song Kaifeng rolled his eyes and asked a question: "What's the chief, it's not that I put forward my opinion, but this battle formation can't be practiced at all!"

"Oh, tell me, is there something wrong with this formation?"

"That's not it, but this tortoiseshell array in order to pursue the ultimate defensive effect, each monk must be equipped with a strong shield, I am light and weak, I have never used a heavy shield, it is really difficult for some strong people!"

Yi Xuan nodded and said: "Kai Feng is worthy of being our scout, it is really a meticulous observation, and the key to finding the problem at once! Originally, I wanted to wait for everyone to practice well before handing out shields, since Kai Feng strongly requested, then I will issue the shield now, and everyone will directly start practicing with the shield!" After speaking, he took out seven shields the size of the door panel from the storage bag, the materials were different but they were all extremely heavy. Yi Xuan had already selected the seven-sided shield magic weapon from the various magic weapons that he had taken from the Lian family before, and seeing that Song Kaifeng was deliberately making this excuse, he simply took it out directly, picking the largest and bulkiest side of it and holding it in his hand.
