"Hey!" Seeing the danger of human beings at this time, only one head was left, and he couldn't help but become tearful, he glanced at the city in the distance stupidly, as if he could see Lu Xihua who was fighting in Yanjing City, and the figure of Rin.

"How? Have you decided? After waiting for a while, the Tongtian Sect Master asked lightly.

“…… The master doesn't need to persuade anymore" Gu Han smiled, "The apprentice is not stupid, this four swords of the immortals is probably the key to the master's destruction of this world." If the master couldn't get the four swords of the immortals, then this world might still exist. But if the master obtains the Four Swords of Zhuxian, then we humans are the real place where we humans die without burial! Even if there are 30 more years, it's just a cup of loess! No, I'm afraid there won't even be loess by then! ”

"You can see it!" The Tongtian Sect Master sneered, but he didn't deny what he said, he didn't seem to want to persuade Gu Han anymore, but left here directly, and before leaving, he warned the guarded Wudang Holy Mother and Yunxiao Niangniang, so that Gu Han must not have a moment to rest, and he must always let Gu Han's eyes be fixed on Yanjing City, so that Gu Han can see everything that happens in Yanjing City anytime and anywhere.

Soon, the reason for the Tongtian Sect Master's orders was revealed.

On the second day after the disappearance of the Tongtian Sect Master, the Yuankou army was finally prepared, and the combined armies of the four major forces, as well as some small forces that had been heralded by these four forces, also appeared one after another, and launched a desperate attack on Yanjing City together with the four major forces.

Fortunately, Yanjing City's dimensional wall protection system has been repaired, and the human race can rely on the complete dimensional wall to resist the attack of the Yuan Kou army, and the two sides have been in a stalemate around the dimensional wall for a full day. Although Yuan Kou attacked very bravely, he did not make much progress. After all, Yanjing City's dimensional wall protection system is extremely thick, and even the Twelve Ancestral Witches have attacked for half a year to break through, and it is impossible for the Yuan Kou army to destroy the dimensional wall in just one day.

What all humans didn't expect was that that night, with a roaring explosion under Yanjing City, the entire super-dimensional wall protection system came to naught in an instant. When the human sword-wielder was in a sleep, Yanjing City's greatest means of protection had already been destroyed.

"There's an inner ghost! There is an inner ghost who has destroyed our dimensional wall protection system! Countless sword-wielding men wailed, this sudden news completely disturbed the minds of all human beings, and the originally stable and calm human beings suddenly became extremely frightened. They couldn't figure out how the core control room of the Super Dimensional Wall Protection System, which was so well protected and guarded by several Spirit Sword-level sword holders, could be completely destroyed by the opponent in an instant, and those Spirit Sword-level sword holders guarding the door died in the hands of the opponent without even having a moment to react.

Of course, it is impossible for the Yuan Kou to let go of such a wonderful opportunity, as soon as these Yuan Kou noticed the destruction of Yanjing City's dimensional wall protection system, they immediately regrouped their troops and killed Yanjing City like a surging river. In a hurry, under the leadership of Lucihua and Liu Nianrin, the human race stood on the head of the city regardless of life and death, and began to fight to the death against these Yuankou on the city wall.

The resistance of human beings is heroic, but Yanjing City is too big, the wall alone is hundreds of kilometers long, and on average, less than five sword-wielders can be assigned to guard it every hundred meters.

In an hour's time, the casualties of the human sword-wielders broke through the outermost city wall of the number of thirty percent and were breached, and the human beings began to retreat frantically, directly giving up the sixth, fifth, fourth, and third walls behind, and all the sword-wielders gathered on the second city wall, barely blocking the crazy attack of Yuan Kou.

Because the second wall is the wall that protects the entire core area, and it is also the last barrier for humanity, thanks to the resistance of the sword-wielding in the outermost wall for an hour at the beginning, a large number of ordinary people can all retreat to the core area protected by the second wall.

But when we retreat here, humanity has no way to retreat.

The remaining human refugees are crammed into the core like sardines, with more than 20 people standing there per square meter of land, so you can imagine how bloated the core is at this time.

To put it mildly, at this time, if any Yuan Kou throws a light cannon down, he can kill hundreds or thousands of human beings.

However, it is precisely because of the small size of the core area that the total length of the second city wall is only more than 20 kilometers, and the human sword bearers have formed a complete defense line on this city wall, and the Yuan Kou have not thought of breaking through the defense of this second city wall for a while, so the situation has once again stalemate.

But every human being knows that this stalemate is only temporary, and it is also the last stalemate that humanity can have, once the second wall is breached, then humanity will lose all means of defense, and all civilians will be directly exposed to the attack of the Yuankou.

At that time, the only option available to humanity is to forcibly disperse the elite of humanity to various parts of this world, leaving them to hide and wait for the time to rise again...... Finally, whether there is a chance for human beings to rise again is only known by the will of God.

"Doutian! Doutian! On the second line of defense, a sword-wielder suddenly let out a heart-rending roar, because at this moment, his sword girl was torn to pieces under the siege of more than a dozen Yuan Kou, and the sword body was directly trampled into pieces, and this sword bearer lost his most beloved and last sword girl.

At this moment, his eyes were full of grief and indignation, leaving bright red blood and tears in his eyes.

"Hongjun Sword Emperor! Your Majesty! Where you are, save us! Suddenly, the sword-wielder shouted as if it could pierce the entire sky.

Yes, Hongjun Sword Emperor, where is he now?

"Your Majesty, save us!"

"Your Majesty, save humanity, come out quickly!!" And this shout seemed to have hooked the minds of all the rest, and those sword-wielders who were in grief and fear began to chant Gu Han's name and the name of the Hongjun Sword Emperor, hoping that the most powerful sword-wielder in human history would appear in front of them in time to save them from this desperate situation that was close to death.

"Guhan, where are you...... You're coming back soon! Even Flowing Nianrin, while being surrounded by five Hong-level Yuankou, couldn't help but shout Gu Han's name in his heart.
