When Gu Han heard what Liu Lei said, he didn't answer for a long time, so Liu Lei repeated what he had just said, "From now on, you are my apprentice."

Now Gu Han felt completely ache. Two days ago, he was still silly and wanted to ask Wuzhang Shifang to accept him as his apprentice, but Wuzhang Shifang was very stinky and said that he had to get the first place at the Eighth Academy Conference in order to become his apprentice.

As a result, in two days, a sword-holder of the immortal sword came out and expressed his willingness to recruit Gu Han to feed his disciples. To be honest, just from the quality of the master, Wuzhang Shifang is better than Liu Lei.

First, Wuzhang Shifang is the fifth among the immortal sword-level sword-holders, while Liu Lei is only eleven. In terms of strength, Liu Lei is not as good as Wuzhang Shifang;

Second, Wuzhang Shifang is young enough. Wuzhang Shifang is only in his early fifties. With the physical fitness of a fairy sword-holder, as long as he does not die in the hands of Yuan Gong, it will be no big problem to live for another thirty or forty years. Then Wuzhang Shifang can protect himself for thirty or forty years. In contrast, Liu Lei is already old. Judging from his physical condition, it is difficult to live for three or five years.

Third, there is the Haotian Sword Emperor behind Wuzhang Shifang. At the critical moment, he might be able to be related to the Sword Emperor, and such a safety factor would be much more reliable. But Liu Lei is alone and is said to have an average relationship with the Baiju Sword Immortal.

Although there are so many benefits of worshiping Wuzhang Shifang, Gu Han is more willing to worship Liu Lei as his teacher... Gu Han is an arrogant person, and the test of Wuzhang Shifang has even made Gu Han feel a knot in his heart. However, because he could not find the opportunity to meet the second immortal sword-level sword holder, Gu Han had to endure the test of Wuzhang Shifang.

But now it's different. Liu Lei, the immortal Yunxiao, actually offered to accept Gu Han as his disciple. His attitude was more than ten times better than Wuzhang Shifang. Gu Han was of course willing to take Liu Lei as his teacher... However, before that, Gu Han wanted to figure out why Liu Lei suddenly proposed to be his disciple.

"Senior Yunxiao's wrong love, Gu Han was flattered!" Gu Han first bowed deeply to Liu Lei, and then said, "But Gu Han really doesn't understand what Gu Han is capable of. Since he can receive the favor from his senior, please tell me the truth, otherwise I will not be able to sleep at night."

"You kid, are you afraid that I, Liu Lei, will harm you!" Liu Lei cursed unhappily, "It's okay, it's okay to tell you, so as not to have any kids to me, the master in the future."

"Boy, do you know what the sword-hard era is?" Suddenly, Liu Lei asked Gu Han this question.

"Sword Hard Time!" Gu Han heard these four words and quickly flew out of his mind about the Sword Hard Time. The so-called Sword Hard Time refers to an era when sword holders gradually became rare in history, and new sword holders could not catch up with the dead sword holders. At the same time, the number of high-end sword emperor-level sword holders was seriously insufficient. Such an era is called the Sword Hard Time.

Generally speaking, there are two standards for judging whether an era has reached the sword-hard era. The first is that the annual increase rate of sword-holders is less than 10% of the negative, and the second is that the number of sword-holders of the sword-emperor level is lower than two. If these two standards are met, it can basically be judged that this era has reached the sword-hard era.

Just like a sentence in a classical book "The Three Kingdoms Acting", the general trend of the world will be divided after a long time, and the sword and hard times will be combined. The same is true for the sword and hard times. With about two hundred to three hundred years as a time node, humans will inexplicably usher in the sword and hard times. Before today, humans encountered three sword and hard times... After careful calculation, did the last sword and hard times end 230 years ago? After this calculation, time will also match.

Suddenly, when he heard that the Sword Hard Times were coming, Gu Han's expression changed rapidly. This was an absolute secret for the Sword Commission and a secret that no one could tell. Once the news of the Sword Hard Times began spread to Yuanzhu, then mankind will inevitably usher in a miserable war.

"Senior, it's better if I don't know about this kind of thing!" Gu Han didn't want to know this news, because once he knew it, he would definitely be on the list of key attention of the Sword Committee. Maybe someone would monitor his communication throughout the process to prevent himself from revealing the news about the Sword Hard Times.

"It's okay, you are my apprentice, you are qualified to know this!" Liu Lei seemed to want to tell Gu Han everything he knew. "In fact, according to statistics, the growth rate of sword holders last year was negative 6.87%. Although the statistics for this year have not yet been released, according to statistics from our Yuzhang Sword Committee, the growth rate in the first half of this year has dropped to negative 7.8%. It is estimated that there will be no problem breaking through negative 8% this year!"

"There are only two sword emperors now, Dragon Lion Sword Emperor and Haotian Sword Emperor. In other words, the entire world will officially enter the era of sword difficulties in no more than five years at most!"

"At the lowest five years, the whole world will officially enter the era of sword hardship!" This sentence exploded in Gu Han's mind instantly. Gu Han never expected that he would enter the era of sword hardship from next year. This is simply the news that humans are least willing to hear, which means that in the next twenty to fifty years, humans will face their greatest suffering in three hundred years.

Yes, the sword-hard era is the most difficult era for mankind. Because of the large reduction of sword-holders, humans have to give up a large number of strongholds outside the city because they do not have enough strength to defend these strongholds. If they force themselves to separate their hands to guard, they will only lose their own little power.

Therefore, in the era of Jiandao, humans simply chose to give up their strongholds outside the city, defend all the bases and cities with all their might, and retreat into the city. Looking forward to the past of Jiandao era.

Corresponding to the Sword Hard Times, Yuangu will enter a very active state. They will seize this once-in-a-lifetime opportunity and launch a tide attack on human base cities. At that time, most base cities were protected by poor fairy sword-level sword holders. Once they faced the attacks of Hong-level or Huang-level Yuangu, it would be a naked massacre.

Every time in the sword-hard times, we can hear news that several base cities could not hold on, cities were completely broken, a large number of sword-holders were killed and injured, and almost all civilians died and died.

Yes, after the sword holder cannot defend the city, he can use the power of the sword girl to escape and go to other base cities. However, the civilians can only be ruthlessly abandoned in the city's shelter. If they are lucky, they may be able to hide in the shelter for decades and wait for the past of the sword-hard times.

If you are not lucky, you can only die. By the way, 99.9% of civilians are the ones who are not lucky.

There have been three sword-hard times in total, and the second sword-hard times in the Sword-hard times, Yuzhang City, without an imperial sword-level sword-holder, was unfortunately breached. The humans in the city were basically dead. Only some sword-hard families were transferred to Yanjing City in advance and saved their lives.

After the Jiandao era passed and Yuzhang City was restored, it took a full hundred years to encourage childbirth to restore the number to normal.

Therefore, the era of sword-hard times is a disaster for sword holders, and even more a huge disaster for civilians.

"How could it be, so quickly, there was no sign at all!" Gu Han murmured to himself, all this came too suddenly.

"There are signs that have been around foreseeing the coming of the Sword and Damage five years ago, but we estimated that at that time, there were about fifteen years before the Sword and Damage. Unexpectedly, less than five years have passed, and the time has been one-third ahead of the time, and we are about to welcome this bad era." Liu Lei sighed.

"What's even more terrifying is that the Haotian Sword Emperor may not last for five years. By then, the entire human race will only be the Dragon Lion Sword Emperor, one sword emperor. Even in the first three sword eras, at the worst time, we humans will have two sword emperors, but now we enter the sword era, there will only be one sword emperor left in humans."

"This time the sword hardship era will probably become the most serious sword hardship era in human history." Liu Lei's eyes were filled with endless worries. "Among the eight major base cities, Yanjing City has the deepest heritage and the most sword emperors were born. In the first three sword hardship eras, Yanjing City had the protection of a sword emperor, so Yanjing City has not suffered much losses in the sword hardship era. But this time, even Yanjing City lost the protection of the sword emperor. Maybe, this time our Chinese bloodline will have to endure extremely terrifying disasters."

"Why tell me this!" Gu Han raised his head and looked at Liu Lei tightly. "These things are not something that ancient sword-holders like me should know. Why should I tell you these things?"

"First of all, correct your mistake. You are no longer an ancient sword-level sword-holder, you are already a sword-level sword-holder!" Liu Lei was in a mood to joke. "If you ask me why you tell you, then I will tell you, because I am optimistic about you! Or, I am more optimistic about the Admiral!"

"Admiral!" Hearing this name, Gu Han suddenly raised his head and looked at Liu Lei in disbelief. How did he know that he was the Admiral?

"Don't be surprised, Gu Han." Liu Lei patted Gu Han's shoulder. "My old guy's biggest pleasure is to brush copies in "Sword Girl OL" and break fragments. Just so happens that a friend's son was fooled into the Yaoguang Sword Sect. He knew that the admiral had a sword in his hand, which was not difficult. Just so happens that you sent this message to me, this is fate!"
