The "Tongtian Sect Master" was a little speechless after seeing the large pile of top-grade materials that Jian Wuchen took out. Because, some of these superb materials that Jian Wuchen took out were what he wanted very much, which made him speechless, the wealth of his disciple was even richer than that of his master, which made the Tongtian Sect Master, who had always had a good face, a little shameless on his face.

However, the "Tongtian Sect Master" didn't care about these trivial things, he picked out some of the best materials suitable for arranging the formation from these materials of Jian Wuchen. Of course, those ten "Tiangang Holy Stones" were also taken by the "Tongtian Sect Master" to arrange defensive formations.

"Dust-free, the materials for arranging the defensive arrays are almost the same, and after the division has arranged these defensive arrays completely, you are fusing the "four-color Eight Treasure Lotus", remember, you must first fuse the two together, and finally fuse them in pairs. If, with the fusion of your plants, there will be two Destruction Tribulations, one is the "Chaos Blue Lotus", and the last one is the "Destruction Tribulation" of the "Four-Colored Eight Treasure Lotus", do you understand?" "Tongtian Sect Master" admonished Jian Wuchen and said.

"Thank you Master for informing me, otherwise, the disciple will really fuse one by one," Jian Wuchen heard the information of his master "Tongtian Sect Master", and said with a sigh of thanks.

"Okay, you kid is here to help, refine all these materials, you have the Chaos Divine Fire, refine these materials faster," the Tongtian Sect Master said to Jian Wuchen.

"Yes, Master, the disciple respectfully obeys the master's orders," hearing his master's order, Jian Wuchen immediately replied.

Immediately, Jian Wuchen used the "Chaos Divine Fire" and began to refine the pile of materials in front of him. At this time, the Tongtian Sect Master was not idle, and he was also refining materials on the side.

Time passed little by little, and three days later, those two piles of top-grade materials were all refined with the joint efforts of the "Tongtian Sect Master" and Jian Wuchen, the master and apprentice.

"Wuchen, we have finished refining the materials, now, for the master to carve the runes of the defense array, if you want to learn, just watch it carefully, if you don't understand anything, you can ask me at any time," the Tongtian Sect Master put away all the refined refining materials, and said to Jian Wuchen.

"Hehe, it just so happens that the disciple is a little interested in arranging the formation, today, the disciple must learn from the master," Jian Wuchen heard the words of his master "Tongtian Sect Master", he replied with a smile.

"As long as you are interested and want to learn, then the teacher will definitely teach you and ensure that you will become the strongest "Formation Grandmaster" in the "Three Thousand Worlds", "When the Tongtian Sect Master heard that Jian Wuchen wanted to learn the formation, he opened his mouth and said to Jian Wuchen.

Immediately, the "Tongtian Sect Master" opened his mouth and introduced Jian Wuchen and said: "Wuchen, the first formation that the master wants to arrange, called the "Tianji Thunder Gang Array", needs to use the "Heavenly Thunder Yuan Iron", "Xuan Lei Pillar", "Bafang Yin Thunder Stone", and the array eye is used in the main array of the saint-level material "Taigang Holy Stone", and is using the power of the thunder system law to outline the Heavenly Thunder Wuji rune, connect the Heavenly Dao Thunder System rules, and form a thunder net, even if it is the "Mixed Yuan Heavenly Dao" The powerhouse of the early stage realm, there is no time for ten breaths, and it can be broken by resting, and it is estimated that it can resist the power of the three heavenly tribulations," "Tongtian Sect Master" carefully introduced Jian Wuchen while arranging the formation.

"Master, what you just said, the disciples have memorized it, but there are some details and outline runes that I don't understand," Jian Wuchen replied.

"Don't understand those details and runes?" the Tongtian Sect Master asked when he heard Jian Wuchen's words.

"Master, I don't understand the details of the arrangement and the matching of the runes that you just said," Jian Wuchen said something he didn't understand.

"The matching between materials and runes depends on the degree of fusion between the two, for example, the gap between this "Heavenly Thunder Yuan Iron" and "Xuan Thunder Pillar", you need to connect them with three runes, so that the two can be perfectly fused and maximize their power, do you understand?" Hearing this, the Tongtian Sect Master said something he didn't understand, and opened his mouth to explain to him.

"Oh, I understand now, thank you for the teaching," Jian Wuchen saw that his master had carefully guided and explained to him, and he immediately understood the key between the two, and replied with a thankful voice.

A quarter of an hour later, the "Tongtian Sect Master" completed the first formation "Tianji Thunder Gang Array", and the moment the large array was completed, in the sky, the sky was thundering, and countless violent thunder aura surged towards the large array.

A full three hours later, the Heavenly Thunder Aura condensed in the sky above the "Biyou Palace" was all absorbed by the "Heavenly Extreme Thunder Gang Array", and a terrifying aura emanated from this large array, just with a breath, it made Jian Wuchen's scalp numb, and he felt that he was in front of this large array, like an ant, just like facing a strong man in the realm of "Mixed Yuan Heavenly Dao".

"Wuchen, this 'Heavenly Pole Thunder Gang Array' is not only a defensive and offensive array, it is also a spirit array of innate thunder physique cultivation, as long as they cultivate in it for one day, it is equivalent to a year of cultivation outside. If this great array can be refined and sealed in their bodies, then it will be even more terrifying, but this requires the top-level innate thunder body, the owner of the "World Destroying Thunder Body", to seal this great array in their bodies, and other innate thunder bodies can't withstand it, the power of this great array's violent thunder," the Tongtian Sect Master said in a shocking voice.

"What?"

"Master, you just said that this great array can also be sealed in the cultivator's body, and become a part of the cultivator?" Jian Wuchen asked with a shocked face when he heard his master's "Tongtian Sect Master" say this.

"This cultivation method is a cultivation method that the master inadvertently thought of, that is, to use the cultivator itself as the energy source of the formation, and to refine and integrate the large array into one, when the time comes, he will be able to use the power of the large array to kill his own enemies, however, the cultivator's own conditions are very harsh, and it takes heaven and earth, the top innate spirit body and the ten major dao bodies to cultivate, but the potential threat of this cultivation method is also very large, and the first thing that is difficult to solve is that the energy problem consumed by the large array is not thought of by the teacher now, The Tongtian Sect Master said in a shocking voice.

"Master, why don't you refine a powerful puppet, arrange a powerful formation on him, and then, arrange a super spirit gathering array on him, let him absorb the aura of heaven and earth by himself, and let him have enough energy to urge the formation to attack, isn't it the same?" Jian Wuchen heard the words of his master "Tongtian Sect Master" and proposed.

"Puppets can't do it, they don't have their own thinking, they can only be tested on the body of a cultivator, but unfortunately, this method is against the way of heaven, and I will give up on it," the Tongtian Sect Master heard Jian Wuchen's proposal and said to him.
