In the swamp, two figures were running towards the Bluestone Fort at an extremely fast speed. They passed through mud ponds and through the woods, like two light birds.

Suddenly, two monsters in the mud pond ahead jumped up and attacked the two of them.

Liang Bo's expression remained unchanged, and the long sword in his hand slashed out quickly.

"Puff! Puff!" Two sword lights flashed by, and the two monsters died on the spot.

Liang Bo and his two men were not affected at all and continued to run forward.

"Senior sister, what happened to the Bluestone Fort, and it suddenly sounded the horn of war? Logically speaking, we have not noticed any abnormal movements in the past two days. Even if the Monster is preparing to attack the city, it will take at least one or two days to prepare? Why did we not receive any news and Bluestone Fort be attacked?" Liang Bo asked while running.

"How could I know? Maybe our people discovered that the demon army was gathering, so they sounded the horn and called us back?"

Liang Bo frowned and said, "It is impossible. According to regulations, only when Bluestone Fort is clearly attacked can the horn of war be sounded. If only the enemy situation is discovered, you only need to beat the war drum to warn. There is no need to blow the horn so eagerly. I think something unexpected happened."

"Who knows? Forget it, it's not far from Bluestone Fort anyway, we will naturally know when we go back." Luo Qian replied with a smile.

Although the Bluestone Fort was likely to be attacked, she was not worried at all, because the Bluestone Fort is a fortress that the human race has been running for many years, with extremely strict defenses. There are tens of thousands of defenders in the city and many strong men to guard them. Although there are no strong men in the Tianyuan Realm, there are many strong men in the city who are second only to the Tianyuan Realm Peak.

With such strict defense, the demon clan would not expect to take down the Bluestone Fort in a short time unless he sent a Heavenly-level Demon Lord to attack. If the demon clan dispatched the Heavenly-level Demon Lord, the Sword Master who was in charge of Wuchuan would never sit idly by.

So in Luo Qian's view, Bluestone Fort should be as stable as Mount Tai, so there is no need to worry at all. Even in her view, the demon clan launched an siege at this time was the best time to hunt for military merits, because compared to usual, when defending the city, they not only could use the formations in the city, but also the monsters were also constantly coming over, and there was no need to search at all. The efficiency of obtaining military merits in this way was naturally much higher than usual.

"Yes, let's speed up, the Bluestone Fort is not far ahead." Liang Bo nodded slightly, his expression also relaxed.

However, just when the two of them are relaxed.

"Douwuwuwuwu..."

At this moment, a rapid sound of horns came from the direction of the Bluestone Fort in the south.

However, unlike the sound of the horn just now, the sound of the horn this time was even more rapid and even more shrill, as if the situation had reached its most critical moment, and the Bluestone Fort could be captured by the demon army at any time.

"How is it possible? How could the situation in Bluestone Castle suddenly deteriorate to this level?" Liang Bo and Luo Qian were stunned. They looked at each other, their eyes full of shock.

With the defense ability of Bluestone Fort, even if there are 100,000 demon clan troops attacking, as long as there is no Heavenly Demon Lord taking action, it is impossible to put Bluestone Fort into danger in such a short period of time.

"Can it be that the demon lord of the demon clan took action? But if the demon lord took action, why didn't the master stop the other party?" Luo Qian accelerated suddenly, and her whole body rushed towards the Bluestone Fort like a flash of lightning; Liang Bo also quickly accelerated to keep up.

When they arrived at a place that was only two or three miles away from Bluestone Fort, Liang Bo and the other two jumped onto a towering tree and looked far away in the direction of Bluestone Fort.

When they saw this, the two were stunned.

"This...this is impossible!" Luo Qian murmured to herself.

What did she see?

I saw that outside the Bluestone Fort, a shocking battlefield had turned into a terrifying battlefield. Tens of thousands of demon clans were launching a fierce attack on the Bluestone Fort's wall. What was even more shocking was that a gap of nearly twenty meters wide had appeared on the Bluestone Fort's wall, and countless demon clans were rushing into the city from the gap!

"Have the demon clan already attacked the city?" Liang Bo was a little confused.

Originally, after hearing the second round of war, he had already predicted that the situation might not be good, but no matter how bad the situation was, he never expected it to be so bad that the demon army had already entered the city!

"There is a traitor!" Then the two spoke at the same time.

In the situation in front of him, Liang Bo and the other two did not see a Heavenly-level demon lord appearing on the battlefield. Since it was not the Heavenly-level demon lord, and the demon army invaded the city so quickly, there was only one possibility, that is, there was a problem inside the Bluestone Fort.

Moreover, in the observation of the two, the moat formation of Bluestone Fort had not been activated at this time, and it seemed that it had been destroyed by someone. This also means that there were traitors in the city, otherwise it would not have been possible.

Of course, in addition to the traitors, Liang Bo also had another problem that he couldn't understand, that is, how the demon army concealed the eyes and ears of the human race and suddenly rushed to the city of Qingstone Fort.

You should know that the number of demon clan army on the battlefield in front of you is at least 30,000 to 40,000. With so many demon clans gathering and mobilizing, it is impossible for them to have no movement at all.

Even if there are traitors on the human race, the number of people will never be too large. If the demon race gathers and mobilizes on a large scale, it is impossible for the human race to receive no information.

Luo Qian said with a grim expression: "I know what's going on, it should be a teleportation array."

"Teleportation array?" Liang Bo exclaimed.

"Yes, the technology of the teleportation array construction of our human race has long been lost; there are still some incomplete means on the demon race. Although the inheritance is incomplete, the construction of the teleportation array alone requires a lot of time and resources, and the teleportation distance is very close, but it is much more advanced than our human race. I think the demon race should have secretly built a teleportation array near the Bluestone Fort, so that the demon race army can be continuously transmitted over in a short time, and thus launching a sneak attack on the Bluestone Fort. Of course, to achieve this step, there must be a cooperation from the traitor, otherwise the teleportation array will be built for a very long time and it will be impossible not to be discovered."

"Are you a traitor?" Liang Bo's eyes were full of murderous aura.

Whether on earth or in this life, the people he hated the most were those who betrayed his own ethnic group. Such people were more hateful than real enemies; since those real enemies were already clearly chariots, they just need to kill them all, and there would be no emotional burden; however, it is even more heartbreaking for those betrayers.
