The steps are very simple, everyone just need to follow the steps.

Lu Ming, Xie Nianqing, Qiu Yue, Ling Yuwei, Dandan, Bubble, Wanshen, Ball Ball, Bone Demon, Tang Jun, a group of ten people, each holding an iron card and starting to refine it.

Refining iron cards is actually very simple. Not long after, Lu Ming and others refined all the iron cards and could freely put them into the sea of ​​consciousness.

The hardest thing is the runes above.

When they refine the iron plate, a piece of information will automatically be transmitted to their minds on the iron plate.

This piece of information is a piece of formation.

There is not a complete formation, it is just one section of a formation. Each of them ten of them obtained a different formation.

Everyone must fully master the corresponding formation, and then cooperate perfectly and use the iron card as the carrier to display the combined attack formation.

They did not stop at all, and they didn't have much time left, and they had to master it as soon as possible.

As soon as he comprehended, Lu Ming felt that this formation was very obscure and difficult to understand. After comprehending for a while, the progress was extremely slow.

He opened his eyes and found that Wan Shen, Bubble, Ling Yuwei, Qiuyue and others were all frowning, obviously they had encountered a problem.

They were not very good at formations, and this formation was obviously left behind by the last era, which was even more difficult.

Xie Nianqing, Tang Jun and Bone Demon are better. In the past, they were all realms of origin, and they had a foundation there, so they had to understand them smoothly.

The easiest thing is naturally Dandan.

His turtle shell glowed, and dense runes enveloped him, looking very smooth.

After pondering for a while, Lu Ming continued to comprehend.

Cultivators in the divine realm will have some knowledge of formations, because some simple formations are sometimes very practical.

Especially the deeper your cultivation level, the deeper your understanding of the cultivation level, and the deeper your understanding of the formation level will be.

For example, even if a strong man in the Divine Lord realm does not deliberately practice the formation, his control over the formation is still stronger than a formation master in the True God realm. This is the difference brought about by different realms.

Therefore, Lu Ming and the others were able to comprehend this formation, otherwise it would be impossible to comprehend if they knew nothing.

Dandan was very fast, but it took three days to understand the formation on the iron plate.

"Although each of us wants to comprehend different formations, there are similarities. I will tell you some of the experiences I comprehend and summarized."

Dandan asked Lu Ming to temporarily stop comprehend and explained some of his experience in comprehending this combined attack formation in detail.

With the guidance of Dandan, the formation master, Lu Ming and others' speed of understanding was indeed greatly improved.

A few days later, Xie Nianqing, Tang Jun, and Bone Demon also successfully comprehended it one after another.

Lu Ming is getting closer and closer.

After all, each of them is a genius, with extraordinary insights, and is much faster than ordinary people.

A few more days later, after they comprehended the formation for ten days, Lu Ming, Qiu Yue, Bone Demon, Bubble, and Ling Yuwei also successfully comprehended it one after another.

"Come on, try setting up the formation!"

Dandan was already a little impatient.

For a formation master like him, he was really curious about the combined attack formation left by the last era.

"Design the formation!"

Lu Ming shouted lightly, and suddenly, a group of ten people flashed according to the formations they mastered, and stood in different directions.

At the same time, the iron plate appeared around their waists, and runes filled with mysterious rays of light. Between ten people, the rays of light intertwined, slowly condensing a huge figure.

This figure is adult, with ten people, two of them having heads, two of them having torso, two of them having left and right arms, and one of them having feet.

However, the figure was very blurry and not solid enough. You could barely see that this was a person covered in dark armor. The armor seemed a bit ferocious, with sharp barbs on his wrists and shoulders.

This figure, holding a battle halberd in his hand, looked like a striking majesty.

However, when Lu Ming and the others were about to use the formation and control the figure to attack, the figure trembled and collapsed.

Failed!

"What's going on? We have clearly mastered the formation, why can't we succeed?"

All gods spoke in confusion.

"That's because the cooperation between us is not perfect enough, and we must strengthen our practice."

Dandan Road.

"Okay, start over."

Lu Ming said.

They continued to try to set up the formation, but unfortunately, the figure that condensed was still blurry and soon dispersed.

The difficulty of this combined attack formation is indeed very great.

According to normal procedures, even if there is a formation carrier, it takes a long time for the people who control each other to practice and work in order to perfectly arrange it.

However, there is really not much time left for them. They must arrange it as soon as possible and practice must be stepped up.

They fell into crazy practice, and forgot to eat and sleep, and then five more days passed.

After five days of continuous practice, their mastery of the combined attack formation has improved a lot, and the figures condensed have become much clearer, and the time it has existed has been much longer, reaching about one minute.

Moreover, they tried to launch an attack, and the power was indeed very amazing, and the attack power was a little higher than that of the strongest Heavenly Lord.

Unfortunately, it still cannot be perfectly arranged, and it always feels like it is one step away.

"This last step is very difficult. There are only two ways to succeed. One is to succeed after a long period of running-in."

Dandan Road.

"What about one more?"

Wan Shen asked quickly.

"There is another one, that is, facing a life-and-death crisis. In the crisis, it succeeds with the pressure of the crisis and makes perfect arrangements. However, it is very dangerous and may lose your life."

Dandan Road.

"The nest...it seems that it will be difficult to succeed in a short period of time."

The gods muttered.

"Don't be discouraged. Even so, our strength is much stronger than before, at least within a minute..."

Lu Ming smiled and comforted the gods.

This combined attack formation is very extraordinary. Although they cannot perfectly arrange it, the minute they are arranged it still greatly increases their strength. Not to mention anything else, at least the attack power is approaching Gu Changfeng's level.

At this moment, Lu Ming received a message from Cangqiong.

"The war is about to begin, and the Yuanguang tribe is about to start siege."

Lu Ming spoke with a serious expression.

They have no time to get started.

After waiting for half a month, the Yuanguang tribe finally began to attack the city, and most of them waited for reinforcements.

"Walk!"
Chapter completed!
