Under Zangtian's guidance, Ji Tianxing successfully activated the formation in only two hours.
Of course, this divine formation is extremely profound and is still beyond his ability to comprehend and control.
All he can do is activate this divine formation.
As for how the divine formation operates, what mysteries it contains, what its structure is, etc... it has nothing to do with him.
After the divine formation began to operate, the ground in a radius of hundreds of feet lit up with golden light, and overwhelming seal characters and mysterious symbols poured out.
Endless ancient characters and symbols swirled and danced like butterflies, and surged toward the Nine Heavens Divine Cauldron like a tide.
The huge Nine Heavens Divine Cauldron also glowed with sacred golden light, and many patterns and words appeared on its surface.
Within the divine cauldron, the Void Divine Fire emerged at the right moment, turning into black and purple clouds and mist, spinning like a vortex inside the cauldron.
Invisible power permeated the entire hall, doubling Ji Tianxing's pressure and causing him to sweat like raindrops all over his body.
"Tian Xing, you can practice with peace of mind. I will be out of seclusion in three months."
Zangtian gave an instruction, then flew into the Nine Heavens Divine Cauldron and entered the black-purple void divine fire.
Ji Tianxing followed its instructions, put the six weapons-refining materials into the divine cauldron one after another, and quickly left the hall.
"Whoosh!"
After leaving the Shenbing Pavilion, he returned to the Tomb of the Sword God and appeared in front of the black tombstone again.
Next, what he has to do is to understand the third level of the Sword Soul Way and continue to practice in seclusion to improve his strength.
His soul returned to its true form, and he began to meditate on the techniques and work hard to improve his strength.
The palace master told him before that the cultivation resources of the four of them were enough to support the operation of the secret room for two months.
Two months in the outside world is twenty months in the secret room.
He still has four months, and he must take advantage of this time to increase his strength as much as possible.
…
In Zhongzhou City, the situation is getting increasingly tense.
The scouts on the front line will send back the latest news every day, reporting on the movements of the demon army.
Three days ago, the demon army was still 150,000 miles away from Zhongzhou, destroying three cities along the way and massacring hundreds of thousands of fleeing people and warriors.
Two days ago, the demon army was 130,000 miles away from Zhongzhou.
Now, the demon army is only 100,000 miles away from Zhongzhou.
The human army in Zhongzhou City can already clearly see the northern sky, which is vaguely covered with a layer of black air, and there are traces of blood flickering.
The demon army is getting closer and closer, and Zhongzhou City is in danger.
The number of the human army has gradually increased to more than 13 million.
The defenses of Zhongzhou City were doubled, and the power of the formations was also raised to its peak.
Countless soldiers and warriors are always ready to fight.
Soon, another five days passed.
This time, there was no need for scouts to report the news. The emperor, the emperor's master, and all the powerful human beings could clearly see the scene in the north.
An army of more than 10 million demons has arrived in Zhongzhou City and stopped thousands of miles away in the north.
The mighty demon soldiers were like a vast black tide, carrying a huge amount of demonic energy and blood.
The demon army stopped and was stationed on the plain thousands of miles away.
While recuperating the entire army, they quickly built a demon army camp and built demon caves and passages underground.
By the evening of that day, the sky in the north of Zhongzhou City was covered by black clouds for thousands of miles, turning it into a dark area.
The howling north wind blew in, mixed with wisps of magic mist, and strong blood and murderous aura.
The human soldiers in Zhongzhou City were all aware of a problem.
All the territory from the north of Zhongzhou City has been lost.
The decisive battle to determine the fate of the human race is coming!
However, the demon army came after a long journey and was not in a hurry to attack.
They camped outside Zhongzhou City and rested for three days without launching an attack.
However, tens of thousands of demon scouts and sentinels have been hovering around Zhongzhou City, always monitoring the movements in the city.
The two sides set up their battle formations inside and outside Zhongzhou City. There were no secrets left, and they both knew each other's military strength.
Both human and demon soldiers all understand one problem.
If something unexpected happens, the human army will definitely be defeated and will never be able to defend Zhongzhou City!
As long as this most sacred city on the continent falls, the Imperial Court of the Human Race will soon be destroyed, and by then the end of the human race will come.
At night, Zhongzhou City was lit up with sparse lights.
In the majestic city lord's palace, the meeting hall was brightly lit.
More than a dozen powerful human beings were gathering in the main hall to discuss military matters with the emperor.
The emperor sat in the first place, and the emperor's master stood beside him.
There are six people standing on the left side of the main hall, namely Sifang Divine General, Yun Zhongqi and Long Yunxiao.
On the right side of the main hall, there are seven powerful soul refiners standing.
These are martial arts experts from the common people who were recruited by the Imperial Court to jointly resist the demon army.
Some of them are the leaders of a powerful force, and some are the leader or ancestor of a top sect.
Others are wandering clouds and wild cranes on the mainland, and even worse, they are hermits who have not been born for hundreds of years.
Even the famous Baili Miracle Doctor in mainland China was standing in the queue.
The human race has billions of warriors, and their heritage is very profound, and countless strong men have naturally been born.
In times of peace, many powerful people keep a low profile and avoid public appearances.
Now at the critical moment of life and death for the human race, even the hermits who do not care about worldly affairs will step forward.
The emperor looked at everyone with majestic eyes and said in a low tone: "You are all strong men of our clan, and you are also the commander-in-chief who stands out among thousands of warriors.
At this critical moment, when our race's survival is at stake, you shoulder the lives of 13 million soldiers, as well as the hope of tens of billions of people!"
Obviously, the twelve soul-refining experts and Long Yunxiao in the hall are the commanders of an army of 13 million, and each of them leads an army of one million.
The emperor paused for a moment, then continued: "As for your duties, we still maintain the status quo. The four gods will respectively guard the four city gates to prevent the demons from attacking separately.
The million-strong army led by the emperor was still responsible for presiding over the five defensive formations.
The remaining commanders remain ready for war at all times and will immediately support other commanders in case of any situation.
The demon army has built a camp outside the city and has been stationed for three days. It must have recovered its strength.
If this emperor's prediction is correct, the demon army will launch an attack tonight or tomorrow night.
After all, it is more beneficial to the demons to send troops to fight at night."
The commanders nodded repeatedly and agreed with the emperor's words.
Only the Emperor, Long Yunxiao, frowned and considered for a moment, then said in a deep voice: "Emperor, now Zhongzhou City has been built by us to be impregnable, and the defense is very strong.
If the Demon Emperor and the First Demon God do not go out to fight, we can withstand an army of more than 10 million demons, and it will not be a problem even if we hold on for a year.
However, once the Demon Emperor and the Ancestor Demon God take action, none of us can resist!
If the defensive formations and city walls are broken by them, Zhongzhou City will definitely fall!"
