After experiencing several undercover sneak attacks, the entire Yanyou City was shrouded in a depressing atmosphere. The monks of the Red Valley www.biquge.info are stricter with their own disciples than with the monks of other forces, and if something goes wrong, they will be investigated.

In this way, many undercover agents of the two great families of Sikong and Situ were detected.

The example of the collapse of the Dao Xuanzong is still in front of him, and the Red Valley does not dare to relax. If the main city on the defensive line falls, the two great families on the battlefield and Sikong Situ are not capable of confronting each other, so a fall will inevitably cause the Red Valley to have nothing to defend.

Mu Xiaotian was still in the underground of the Yanyou Palace, in the Formation Privy Chamber, and Sun Yujie and Chen Lijun, the formation master of the Red Hidden Valley, were in charge of the control, and at the same time familiar with this lower grade Dao level array.

This array is called the Four Elephants to the Array, the four images of the heaven and the earth, and the smelting to one. Guardian attacks can all evolve into four elephants, green dragons, white tigers, vermilion birds, and Xuanwu divine beasts, whose power is fused into one, and can compete with the supreme powerhouse.

Counting that it has gone through four large-scale battles, Yanyou City was able to save thanks to the guardian power of this formation.

"The power of the lower grade Dao level formation is comparable to that of the supreme powerhouse. The power of these four elephants can be dispatched out, and it can suppress the momentum brought by hundreds of thousands of Dao soldiers. "Sun Yujie presided over the formation and had experienced the Great War, so he also knew the power of this inferior Dao Formation.

Chen Liyan looked at Mu Xiaotian, and after these few days of communication, he paid more and more attention to the power of Mu Xiaotian's formation: "Mu Shi's nephew Tianzong is a genius, and he can completely control the control means of the formation in a short period of time, and now if the two great families of Sikong Situ launch an offensive again, they will definitely be able to be frustrated." ”

In the previous three wars, the two great families of Sikong Situ and the Heavenly Demon Sect dispatched an army of 300,000 Dao soldiers, with a momentum that crushed everything. However, it was completely blocked under the Yanyou City.

Last time, it was because the undercover agents of the two great families of Situ suddenly attacked the formation grandmaster who was presiding over the big array, which caused the power of the Dao Rank Great Array to be greatly damaged, and it was almost broken.

Now plus Mu Xiao has three more formation masters, who are enough to completely preside over the big formation and exert the highest power of the formation to fight the enemy.

"The juniors will definitely do their best. Mu Xiaotian responded simply.

The formation was also familiar, but the three of them could not leave this formation privy chamber. It was not to imprison their freedom, but to ensure their safety, lest they cause the last calamity.

Now in the place of the formation hub, other Dao monarchs are not allowed to enter at all, and even the other formation masters who assist in presiding over are fixed, and they are already disciples who have been tracked down.

But at this time, a Dao Jun broke in, and his cultivation was not low, and he was at the peak of Dao Jun's realm.

"Uncle Liu, why are you here? Chen Lijun stepped forward and said.

"I've seen the flow of seniors. Mu Xiaotian Sun Yujie didn't step forward, but when he saw the comer, he still greeted him very respectfully.

The person who came was Liu Qishui, who had a relationship with each other last time, and this time he suddenly came to the privy chamber for some reason. He is the closed disciple of the Liuherong Supreme, and he is also the righteous son, and his status in Yanyoucheng is very high, second only to Liuherong Supreme, so there is no place in the entire Yanyoucheng that he can't go to.

"I'm just going to take a look and see how familiar the two foreign formation masters are with the control of the formation. I'm afraid that the two great families of Sikong Situ will have to launch an offensive again in a short time, and the formation is what we can rely on to defend, and we can't be sloppy. Liu Qishui carefully glanced at Sun Yujie and Mu Xiaotian.

Mu Xiaotian could sense that most of Liu Qishui's attention was still on himself. Although I have an inexplicable emotion for this person, I can't say what it is, so I don't pay much attention to him.

"Oh...... After a few days of drills, Sun Daoyou and Mu Shi's nephew are already very familiar with the control method of the Four Elephants Returning to the Formation, according to my opinion of the master and nephew, the three of us should be able to exert ten percent of the power of the formation. ”

"Good ......" Liu Qishui shouted, very excited, "To be able to bring the four elephants together and exert ten percent of the power, it is enough to withstand the attack of the two great families." ”

"I also ask Uncle Shi to tell Uncle Shi that his old man is no longer a problem in terms of formation. ”

"Hmm......" Liu Qishui nodded, he didn't understand the formation, he could only listen to Chen Liyan's opinion. After receiving the assurance, he had no intention of leaving, but walked around the Privy Chamber.

Accompanied by Chen Liyan, he sometimes inquired about the various formations controlled by some of the formations. Chen Lijun did not hide it and introduced it in detail. Although the formation is the inheritance formation of the Red Hidden Valley, and Liuqishui is also familiar with it, it is because he is not a formation mage, so he does not understand the various artifacts in the place of the formation hub.

The control center of the formation is often a scene where the spiritual power of the formation is derived from the spiritual power in the middle to protect or attack. In the middle of this place is a circular formation hub, and the statues of the four elephants and beasts are arranged according to the direction.

These statues are practiced with the control array hub, which is equivalent to a lower grade dao weapon, which is the core control weapon of the formation. Mu Xiaotian and the three of them were fully in control of this weapon to control the formation.

After Liu Qishui learned a lot, he left naturally. It was as if I was wandering around and came to the Privy Chamber by chance, and I became interested in learning about it.

After he left, Chen Lijun saw that Mu Xiaotian was still staring at Liuqishui who was leaving, and thought that he was a little interested, so he said, "Senior nephew is very interested in me, Uncle Liu. ”

"No, the juniors just think that this senior is different, and the relationship with the supreme predecessor is not shallow, it should not be just as simple as master and apprentice!"

"Uncle Liu, the righteous son of my uncle, accidentally ran into it when he was exploring the southern region in the early years. I heard that Uncle Liushi was originally a disciple of a small family in the southern region of Zhongzhou, because the family was wiped out by the Situ family, so he followed Shi Bozu to my Red Valley. Uncle Liu is a person with super talent, and he has been recognized as the third person with the highest price among the second-generation disciples of my Red Hidden Valley. It was because of the outbreak of the Great War that he did not go to retreat, but came directly to Yanyou City to fight the enemy. ”

"Oh...... I see. Mu Xiaotian seemed to understand, and put away that inexplicable expression, "Senior, I'm idle here anyway, you and I will continue to evolve the formation attack and enhance the tacit understanding, which will not help us control the entire big array." ”

"Okay...... Chen Lijun agreed in one bite, and in this process, it is also a process of learning and communicating with each other. The formation masters of the same level communicated and gave each other a lot of help.

In the blink of an eye, another few months passed. The two great families did not attack, but the major cities did not dare to relax in the slightest, and constantly strengthened the defense line to ensure that they would not be broken in the next big battle.

The infiltration of the major forces into the two great families has also been almost cleaned up. Mu Xiaotian had a chance to come out, but he was not like Sun Yujie, who roamed around the city at will. Now the two Situ families still think that he is still in Fan Yingcheng.
