After I bought it, it was already afternoon.

Su Mu hid in the room, took out the medicine tripod, and refined a batch of healing pills and huiling pills.

By the time the last Returning Elixir had been refined, the night had completely darkened.

"It's time to act. ”

Su Mu put away the medicine pod and looked at the sky outside the window.

The moment Su Mu stepped out of the room, Xiao Ding set up a concealment formation on him, skipping the perception of the female killer and going straight to the surroundings of the imperial city.

Then.

According to Xiao Ding's guidance, Su Mu mobilized the Yin and Yang Taixu Flame, and injected it into the array eye with a trace.

There are more than 500 array eyes in total, and the fire energy required for each array eye is also extremely large.

Su Mu was close to prostration, and he was only halfway done.

I had to stop halfway to pranayama, and only after I recovered did I continue to set up.

Su Mu set up the formation while avoiding the sight of the guards patrolling the city.

Finally, before dawn, the operation was nearing its end.

However.

Just as he was about to inject the last formation stone with Yin and Yang Taixu Flame, an accident suddenly appeared.

"Su Mu, be careful, there is a team of people and horses in the imperial city rushing towards you. Xiao Ding reminded.

"What?"

Su Mu was startled, the movements in his hands subconsciously slowed down, and said, "Was it discovered?"

"I forgot, the big array is about to be completed, the formation at this time has formed a scale, as long as you know a little bit of the formation's martial cultivation, you can sense the existence of this formation, the huge thunder empire, it is impossible to have no formation mage, and, looking at their appearance, it is obviously for you, I think, most of them have been discovered. ”

Xiao Ding said.

"What then?"

Su Mu said anxiously.

"Withdraw first, there are a lot of them, and all of them are strong people above the Huayuan Realm, the two of us can't resist at all, once they are caught, it will be bad. ”

Xiao Ding urged.

"But there's one last one!"

Su Mu said unwillingly.

"Forget it, this is not the main formation, if you lose it, at most it will be a little less powerful, and it will not affect the overall situation, if you don't withdraw now, it will really be too late for a while. ”

Xiao Ding urged again.

In its perception, those people were getting closer.

Su Mu's eyes flashed with a hint of determination, and he turned to leave, but when he was leaving, he condensed a strong Yin and Yang Taixu Flame and forcibly entered the formation.

Although this is not enough to fill this array, it is precisely because of this one.

The Qiankun Yin Yang Burning Sky Array was completely activated.

Su Mu sacrificed his spirit wings and quickly swept towards the outside of Thundering City.

Where he disappeared, it didn't take long for a large group of people to come in a hurry.

"Looks like this guy has already run away. One of them said.

"Now it is certain that there are indeed people here who have set up a formation, you continue to chase forward, and order the whole city to be blocked, not a single fly can fly out! ”

After the words fell, these soldiers divided into two routes, the team continued to search for the people who set up the formation, and the other one swept towards the imperial city hall......

"Su Mu, don't run away, find a hidden place to hide first. ”

Xiao Ding said.

Su Mu nodded, he also thought so, since he had been discovered by the enemy, the enemy would definitely take action, I am afraid that the current major city gates have already laid a net, just waiting for him to leave the city.

For now, Su Mu can only hide first, and then wait for the turmoil to pass, and then find a chance to get out of the city.

This time, Su Mu did not enter the inn, but found an ordinary family and gave them ten gold coins, and they were grateful to Dade for taking Su Mu in.

Su Mu hid in a small room, and Xiao Ding arranged a concealment formation for him.

So, he stayed safely.

The next day.

When the night gradually disappeared and the sky was dyed red, Su Mu woke up from his cultivation.

Then, he flew into the air with the Spirit Wings, watching the movement of the Imperial City from afar.

When the sun showed a corner, a beam of light poured into the earth in the blink of an eye.

Rumble!

Thundered!

Boom!

Boom!

At this time, a violent explosion broke out under the imperial city, and the city wall was reduced to ruins in an instant.

The explosion did not stop, sweeping through the vast energy, centered on the main hall of the imperial city, spreading around.

The loud sound suddenly woke up tens of thousands of people in Thundering City.

Everyone was at a loss.

I don't know what happened, the most majestic building, suddenly collapsed?

Su Mu looked at the huge majestic castle, and in an instant, he was nothing, and finally got a trace of comfort in his heart, his eyes narrowed slightly, and he muttered: "This is just the beginning, wait, five years at most, two years at least, I will definitely uproot the Thunder Empire and remove it from the Garo Continent forever!"

Then, Su Mu returned to the small room.

Immediately entered the Phantom Sky Dark Stone and began to practice in retreat.

As everyone knows, the outside world has been shaken upside down.

The fact that such a well-guarded imperial city could be blown up shows how terrifying the caster is, and now the entire Thundering City is panicked, for fear that this explosion will suddenly appear under their feet.

Emperor Lei Shi, his national teacher, and some of his cronies were all suspended in the sky above Thundering City.

Looking at the imperial city that had been reduced to ruins below, Emperor Lei Shidi's face was full of gloom, and the killing intent in his eyes burst out like substance.

"Do you know who did it?"

Emperor Lei Shi said gloomily.

"My subordinates don't know!"

"Weichen doesn't know!"

Everyone was terrified, this incident was too terrible, the moment the imperial city exploded, most of the people inside were killed, including the young son of Emperor Lei Shi's concubine and monk.

If it weren't for the fact that they were powerful and escaped at the moment of the explosion, I am afraid that they would be lying there like the people who were killed by the explosion below.

"This person can arrange such a strong formation under our noses, it seems that his strength should not be weak. ”

Emperor Lei Shi took a deep breath and gradually calmed down.

"Is the city gate blocked?"

"Back to the Lord, when I found that man, he had already sealed off the whole city, and he could only enter but not go out, presumably the man had not yet gone out. ”

"Then search the whole city, whether it's an inn or an ordinary person's house, don't let go of every corner!"

Emperor Lei Shi said ruthlessly.

Although this incident did not hurt the bones of the Thunder Empire, it also gave them a trauma, after all, it was still a bit embarrassing for such a thing to spread.

The imperial city of the Thunderous Empire was quietly bombed into ruins, such an ironic fact, no matter which emperor it is, it is a bit of a loss of face.

Moreover, among the people who died below, there was also his beloved concubine and beloved son.

He swore in his heart that if he caught this person in the array, he must let the other party know what it means to survive and not to die!

This news.

Like a gust of wind, it soon spread throughout the Thunder Empire.

Not only that, but it was also introduced to the surrounding major empires, including the Bangzun Empire.

Hearing this news, the whole country of the Bangzun Empire celebrated, although they didn't know who did it, but this matter was very happy, and they wished that the entire Thunder Empire would collapse.

And it is precisely because of this.

The Thunderbolt Empire attributed all this to the Bangzun Empire, and as a result, the war between the two countries was brought forward by a few months.

But that's all for another time.

At this moment, Su Mu was comfortably hiding in the Phantom Sky Xuanshi to cultivate.

During this period, the guards of the Thunder Empire also came to search this house, however, no results were found.

The Phantom Sky Stone has the function of blocking all tracking, so he has absolute safety in this except that he can't move.

Three months have passed in the Phantom Sky Stone, and one month has passed in the outside world.

In the passage of a month, the bombing of the imperial city gradually subsided.

A new imperial city is also being built.

On the fifth day of the lockdown ordered by Thundering City, Emperor Lei's guards had thoroughly searched the entire city and found no suspicious people.

On the tenth day of the city's lockdown, the people of the city began to complain.

On the twentieth day of the city's blockade, Emperor Lei Shi saw that no one had been found for a long time, and finally he also thought that the people who set up the formation might have gone out before the lockdown.

And it's not an option to keep locking down like this.

So, on the twenty-fifth day of the city's blockade, the southern gate was opened.

However, those who enter and leave should be searched strictly.

In this way, Thundering City gradually returned to its former state.

However, the imperial city was not built in such a short time, and at their speed, I am afraid it will take at least a year or so.

When Su Mu learned that the city gate was opened, he was not in a hurry to go out.

Going out of the city during this period of time will definitely be strictly scrutinized, and his disguise technique is not very clever, it is okay to deceive ordinary people, if you really meet a master, it will be difficult to escape the scrutiny of the other party.

Therefore, Su Mu practiced in the Illusory Sky Xuanshi for another three months.

During this period, Su Mu was once again promoted to the realm of the sevenfold spirit.

After the past two months have passed in the outside world.

Su Mu walked out of the Phantom Sky Xuanshi and walked towards the gate of the city.

Before leaving, he left quietly, without alarming the ordinary family, leaving only a hundred gold coins.

Come to the gates of the city.

Su Mu found that the inspection at this time was not so strict, and it was basically just a show, so he easily mixed it out with his simple appearance.

Out of Thundering City, Su Mu glanced back at the three big characters on the city wall, and said, "When I come back next time, it's time to change the master here!"

After speaking.

Su Mu sacrificed the wings of the spirit and walked in the direction of the Shengyao Academy.

"Xiao Ding, that woman didn't follow, did she?"

On the way, Su Mu asked.

"Don't worry, the moment you left the city, I laid a concealment formation on you, and she didn't know where we were. ”

"That's good, finally get rid of her. ”

After that, Su Mu ran all the way.

A month later, they arrived within the confines of the Holy Yao Academy.

Shengyao City.

It's really safe to get here.

This is a safe zone, and at the foot of the Shengyao Academy, no one dares to come here to make trouble.

Su Mu came to the door, showed the credit card of the Shengyao Academy, and walked in very smoothly in the respectful attitude of the guards guarding the city gate.
