Of course, Zhang Yifeng's current understanding of formations is far from that of a formation master, but it is enough to compare with ordinary formation masters.
This is also the reason why Zhang Yifeng has the confidence to come here. If he didn't have the slightest confidence, he wouldn't do it.
After all, what he has to face next is a national defense formation set up by a formation master. If he is not careful, it will be nothing more than being discovered. If he is trapped in the formation, or directly strangled by the formation, it will be fun.
That's big.
Time flew by, and soon it was night, with the breeze blowing the leaves and the waning moon like a hook.
After Zhang Yifeng and Mu Tiandao dressed up in disguise, they set out for the imperial city of Zhao's ancient kingdom.
Not long after, the two arrived nearby. Zhang Yifeng looked around and then sent a message to Mu Tiandao: "This national defense formation is extraordinary. You must follow my steps closely and don't make a wrong step."
, otherwise I don’t know what will happen.”
Mu Tiandao responded solemnly: "Don't worry, I understand!"
Zhang Yifeng nodded and started to study immediately. At this time, both of them used concealment techniques, so they naturally did not have to worry about being discovered.
Only people with very special abilities like Bao Yuwen, or powerful people above the Immortal Emperor Realm, can realize it. As long as they don't touch the ancient country's formation, theoretically speaking, nothing will happen.
Zhang Yifeng naturally did not dare to enter the formation rashly. He used his clone and walked around the entire imperial city to understand the layout and nodes of the formation.
Of course, even so, Zhang Yifeng would not be able to break this formation for a while, unless he reached the level of a grandmaster along the way.
Afterwards, Zhang Yifeng began to deduce in his mind, and he had memorized all the nodes of the entire formation.
In this way, Zhang Yifeng calculated tens of thousands of times before determining the starting point for the first step.
"Come with me!"
Zhang Yifeng turned around and sent a message to Mu Tiandao, and immediately took a step towards a node.
Mu Tiandao immediately did not dare to neglect, followed him, and took one step forward.
In an instant, the sky and the earth were spinning, and they saw that the scene around them had changed. At this moment, they had entered the national defense formation.
Mu Tiandao on the side was secretly awe-inspiring, and he couldn't help but secretly admire him for being able to calculate the formation of the formation master. This was not something that ordinary people could accomplish.
What's more, Zhang Yifeng is just a person who doesn't fully understand the battle method.
There is no doubt that the amount of such calculations is huge, and ordinary monks cannot do it at all. Only Zhang Yifeng can complete such a heaven-defying move.
If this was spread, everyone would probably be shocked. Fortunately, there are only two people here, Zhang Yifeng and Mu Tiandao, so there is no need to worry about being known.
In this way, after careful calculation, Zhang Yifeng finally took three steps forward before dawn.
"As expected of the formation created by the formation master, it is admirable!"
Zhang Yifeng couldn't help but say in admiration, secretly admiring the person who set up the formation. Not only was he unique in the formation, but in this sect, there was absolutely no formation master who could do it.
Even Zhang Yifeng has only taken three steps forward.
Mu Tiandao was shocked. Although he did not understand how Zhang Yifeng calculated and what a huge amount of calculations he made, he also understood that this was enough to arrogantly surpass many monks!
At least, for now, they have not been discovered, nor have they touched other things in this national defense formation, so they are still safe.
At this moment, it was already dawn, but with the concealment skills of the two of them, there was no need to worry about being discovered.
What's more, now that they have entered the formation, there is no need to worry.
Next, Zhang Yifeng only needs to concentrate on calculating the next step of the formation.
However, even Zhang Yifeng could not bear the consumption involved, because it not only consumes time, but also consumes physical and mental strength.
At the same time, Zhang Yifeng did not dare to relax, because if they made a mistake, what awaited them would be doomed!
If it were anyone else, they would definitely not do this. This is undoubtedly a risky move, and the possibility of failure is too high!
In this way, Zhang Yifeng made tens of thousands of calculations at every step and moved forward slowly step by step.
In this way, three days later, Zhang Yifeng was only halfway through the process.
Mu Tiandao on the side was wiping cold sweat secretly, fearing that Zhang Yifeng would make a mistake.
"Huh, let me rest for a while to avoid any accidents next."
At this time, Zhang Yifeng finally couldn't hold on anymore, and he looked a little sluggish. This kind of mental consumption cannot be restored by any natural treasures, and can only be restored by oneself.
If Zhang Yifeng hadn't opened up a small world now, he might not have been able to hold on long ago.
Mu Tiandao naturally had no objections. He was not worried about Zhang Yifeng, but just worried that he would not be buried with him here.
After several hours, Zhang Yifeng continued to make calculations.
In this way, Zhang Yifeng finally reached the final step after seven days of calculation.
"Damn, these days have been so torturous. How on earth did you come up with this method?"
Mu Tiandao on the side couldn't help but said with some collapse.
Zhang Yifeng smiled faintly and said: "Even the formation of the formation master will have flaws. It cannot be 100% perfect. As long as the calculation is correct, you can still get in."
Mu Tiandao took a deep breath. He also understood that after each step, there are infinite possibilities for the next step. Zhang Yifeng could calculate it. To him, it was simply abnormal!
At the same time, a grand formation like this to protect the country is not only blessed by the luck of a country, but also blessed by the great road of heaven and earth. It is difficult for ordinary people to even approach it, let alone calculate.
And Zhang Yifeng did this! This shocked Mu Tiandao extremely.
"Okay, there is only one last step left. As long as we succeed, we can enter the imperial city of Zhao's ancient country without being detected by the formation!"
After Zhang Yifeng finished speaking, he closed his eyes and began to calculate. At this time, he couldn't be distracted at all!
Otherwise, it is extremely easy to make mistakes in your calculations. Mu Tiandao on the side also understood and waited quietly.
I don't know how long it took, but Zhang Yifeng finally calculated the result, glanced at Mu Tiandao, motioning for him to follow, and then stepped out.
In the blink of an eye, Zhang Yifeng felt that the scenery in front of him changed again, and a huge city wall appeared in front of him.
Immediately afterwards, Mu Tiandao came out behind him. When he saw the city wall, he couldn't help but was stunned. At the same time, he secretly breathed a sigh of relief. He finally came out!
In the past few days, Mu Tiandao has always been on tenterhooks.
