Twenty years ago, the heart of the Holy City, which symbolizes the ultimate of the continent's Yanshu, suddenly suffered a catastrophe, with fire and rain from the sky, magma gushing from the ground, landslides and buildings. There are even mysterious forces that take advantage of the hurricane to burn, kill, loot, and slaughter.

In order to buy time for the residents of the city to escape, the city lord had no intention of personally leading the Yanshi legion he had formed, the Holy Guard, to fight disasters and save people everywhere to resist the enemy army.

However, in the end, the entire army of the Holy Guard was destroyed, and even Wuxin himself died in this battle.

After this catastrophe, the heart of Tianyan, which had gathered more than half of the wealth of the mainland, was finally destroyed in the fires and became the holy ruins of today. There is not one in the inhabitants of the Holy City, and the total population of the mainland has been sharply reduced by more than half, and the losses in terms of new Yanjia, Yandao books, and the inventions and research results of the past dynasties are even greater than immeasurable.

What's even worse is that, aside from the Holy Guards who once looked down on the world, almost all the Yanshi who were well-known on the mainland at that time also settled in the heart of Tianyan. In addition to their disciples, as well as the floating population who come to make pilgrimages, study, preach, and give lectures, the proportion of Yanshi in the heart of the Heavenly Swallow has always remained at a fairly high level.

Under the nest, there are no eggs. Overnight, the Yanshi on the mainland suffered heavy casualties, especially the group of Yanshu masters who stood at the top of the pyramid of the Yanshi group, almost all of them fought to the end, so there were only a handful of survivors.

This catastrophe, known as Yanshu in history, has set back the level of Yanshu in the mainland by hundreds of years, and it has not yet recovered.

However, the sacrifices of the Heartless City Lord and others were not all meaningless. There are still some Yanshi under their cover, with a large number of Yandao ancient books and countless generations of Yanshi research efforts, escaped from the heart of Tianyan, which can be regarded as a line of Yanshi, leaving a fire.

Twenty years later, these people and their descendants have long since become the strongest force in today's Yandao.

The single family of Tianforging Fort is one of them.

However, compared to the treasure trove of knowledge treasured in the heart of Tianyan back then, this part that was rescued was just a drop in the ocean.

And who would ignore the power of these treasures among the remnants of the Holy City, who had made their fortune with these fragments alone?

As a result, many family sects sent people to enter the holy ruins, rummaging under the vast ruins and ruins to search for the remains of the Yandao.

Some people are lucky enough to find some armor blueprints in this ruin, or book notes that record the skills of the Yan, and they have benefited immensely. Since then, he has soared to the sky and made a fortune.

These deeds continue to stimulate people's nerves. Every year, more and more people enter the holy ruins to hunt for treasures.

However, there is more to this devastated land than meets the eye. What's more, in fact, is a killing machine in all directions.

The Heart of Heaven was destroyed, but all the armor mechanisms erected in the Holy City did not fail. What's more, most of the Yanjia organs, which still retain some functions, have gone berserk after years of no maintenance and management.

At the same time, there would be a strange hurricane blowing in the holy ruins from time to time, and even if the people who were caught in it were not torn to pieces, they would have their bones broken, and the Yan Spirit Power Zhou Tian in their bodies would be destroyed, and they would be reduced to waste.

However, in the extrajudicial land of the Holy Ruins, the greatest threat still comes from the fanatical treasure hunters themselves. After all, instead of searching through the rubble all day long, it is easier and more efficient to directly kill people and loot treasures.

As a result, more and more people entered the holy ruins, but the treasures found were less and less, and more people were never able to set foot on the way home, which in turn led to grudges and vendettas between various forces.

Some people realized that if this continued, the Yanshi on the mainland was afraid that they would die.

Finally, the four strongest Yandao sects, including the Heavenly Forging Castle, couldn't stand it anymore.

The only remaining Yandao masters in the world joined forces, relying on the mountains and rivers to build a Great Wall array, isolating the entire holy ruins from the world. At the same time, four gates were set up, which were guarded by the four poles, and each gate could only be opened with the joint efforts of the four major sects.

Every once in a while, the four major sects will organize a team to choose one of them to enter the holy ruins to search for treasures together, and it is strictly forbidden to kill each other. The qualification evaluation of candidates for participating in the treasure hunt was also completed by the four major sects, which put an end to the situation that people with poor strength wanted to go in and find death.

After some rectification, the craze for treasure hunting in the holy ruins was finally rationally curbed. The mainland Yandao, this is the real beginning of recuperation.

However, because of this, the four major sects that controlled the holy ruins further grew into the four poles of the Yandao in a short period of time after that, and there was a lot of distance from other Yandao sects.

The small sects are jealous of the development of the four poles of the Yandao, but unfortunately their strength is not good, and they can't compete with these Yandao giants. The right path of treasure hunting in the holy ruins was restricted, and they had to find another way. Some chose to become vassals of the four poles, looking forward to drinking soup behind the big brother's ass. More chose to start secretly searching for the Yandao treasures that had wandered in the world, after all, the remnants of the Holy City back then would have more or less private hiding.

But in this respect, how can they win over the four poles of the rich and powerful Yandao? It is nothing more than a matter of giving it a try and obeying the destiny of heaven to the best of their ability.

No, Bu Zhidao got an ancient book by turn, didn't he dedicate it to the single family.

"No, this is the only clue at the moment, and we can't give up easily. ”

Ning Le muttered: "It's unlikely that the Shan family will obediently lend us the ancient books for reference, so we can only find a way to sneak in and find out what to see." ”

"Are you crazy or don't want to live?" Bu Zhidao was frightened by his words, "Do you know how many guards and how many armor mechanisms there are in the inner city of Heavenly Forging Castle? ”

Ren agreed: "Don't forget, you were almost arrested by the city guards yesterday. ”

Ning Le said angrily: "Then what should I do, I can't sell myself as a slave and get in, right?"

"That's not necessary. Ren smiled and pointed at the Buzhi Knife, "Don't forget, isn't there a good opportunity to enter the inner city openly?"

"You mean the guest selection?"

Ning Le's eyes lit up, and then he shook his head again and again: "No." The young master only had a hard fight with the city defense yesterday, and now it's too late to hide, do you still have to send it to the door yourself? It's convenient for you, and few people still recognize you now, why don't you go?"

"This girl wants to go. Ren pouted, "It's a pity that people don't necessarily look down on me!"

“...... You are self-aware. Ning Le looked up at the sky helplessly.

"Don't worry, this girl has taken care of it for you. ”

Ren patted him on the shoulder: "This time, the Heavenly Forging Fort recruited guests, the threshold conditions were extremely open, and the treatment was generous, attracting many hidden old monsters and their disciples and grandchildren to go out of the mountain. Most of these people have quirky personalities, and it's not surprising that one or two of them don't like to show their true faces, and even have a strange disease that will die without a mask!"

Ning Le gave her a pair of white eyes: "And then, you plan to enter the inner city and wear a mask all the time? Can people trust such a person and provide you with a collection of ancient books to borrow?"

"Are you stupid?"

Ren gave a reward and a roll of the eyes: "As long as you can enter the inner city, are you afraid that you won't find a chance to peek at a book or two?
