When everything in the main city had completely calmed down, it had been two days since Tang Tian returned, and the issue of human beings being unable to have children had completely subsided, although countless people were still discussing it, but it was not causing any big disturbance.

In the past two days, the departments of the main city have been running at high speed, and soon "invited" experts from all walks of life through various channels, and exchanged a large amount of scientific research equipment from the arena at any cost for these experts to conduct research.

Soon after, the main city announced a news, it is not that humans are unable to have children, but the odds of not knowing weishenme have been reduced to a terrible point, almost one in ten thousand, but it can give birth to life, giving people a little hope.

Immediately afterwards, it was reported again that after hundreds of "experts" studied day and night, the most primitive human embryos have been cultivated through artificial insemination, and new life can be born only after the time is up, but the probability is still very small, and further research is still underway......

After the news was announced, everyone cheered and rejoiced that human civilization could be passed on, and people no longer worried about the future.

When the news in the main city was delivered, Shijie boiled, and the gloom in everyone's hearts was swept away, and a beautiful vision for the future bloomed anew, at least on the surface.

Unlike the news that others got, Tang Tian also got a data from hundreds of experts, the human sperm and eggs are normal, there is no collective necrosis, and artificial insemination has been successful, which was originally a happy thing.

However, the end result is that success is success, but the successful fertilization egg dies for no reason after a minute of success without any warning. He died in the cultivation trough and couldn't find the reason!

The experts were in an uproar, in disbelief, and did not understand that all this was weishenme, and every detail was not wrong, but the final embryo of weishenme could not survive? Some people questioned it. It is said that there have been unknown changes in the world that make it impossible for the baby embryo to survive, but some people refute it, because the normal sperm and eggs are alive, and the weishenme has already combined and died? So I experimented again and carried out artificial insemination inside the human body, but the result was still that after the combination was good, I died for no reason and could not survive!

After the report, Tang Tian shook his head and smiled bitterly, which further confirmed the guess in his heart. One step closer to the idea in my heart.

"If it's really what I imagined, I'm afraid it will take a long, long time before a new life is born, and how long is it ......," Tang Tian said to himself helplessly, looking at the sky.

Yes, the news obtained by the outside world is just fake news released to stabilize people's hearts, and it still cannot solve the fact that human beings cannot give birth to new life.

Zuihou, Tang Tian had to order the experts to continue the study. From time to time, new data is provided to paralyze the outside world, and it can be delayed for as long as it wants. When it really can't be delayed, Tang Tian will consider telling the guess in his heart!

Early in the morning of the third day, Tang Tian, Zhao Yue'er, Zhao Daniu, and Lin Tian stood on the edge of the teleportation array in the barracks, looking at them. Tang Tian opened his mouth and said: "This time I went to Sword Casting City, I must completely eliminate the flowing wind, his existence has always been an unstable factor, and this person is extremely dangerous, and he has already controlled the entire Sword Casting City. Moreover, it is very likely that several leaders in Sword Forge City have been controlled, and it is extremely dangerous to go, so you must be careful."

"Hehe, don't worry, city lord, no matter who he is, I Da Niu will keep a stick to blow him up", Zhao Da Niu scratched his head and smiled, once again recovering his nervous character, where is there still that kind of shrewdness above the meeting?

"The reborn should not exist on this shijie in the first place, this is completely breaking the rules of this world, and this person has a bad heart, and there is no regret in killing him", Lin Tian said.

"Well, then, let's go, after arriving at Sword Casting City, don't act rashly first, and get rid of him in one fell swoop after finding his place to stay", Tang Tian finished speaking, and took the lead in stepping into the teleportation array, and several other people also walked in without hesitation.

Tang Tian and they just went to kill people, not to attack the city, there was no need to lead the army there, they only needed to kill the flowing wind and naturally all the problems could be solved, and the reason why they brought them was mainly to prevent the few people controlled by the flowing wind.

Tang Tian's four people, each of them can be called an existence standing at the top of the pyramid, and anyone's strength is not inferior to a terrifying existence like Lie Yang Tian, and they go to kill Liufeng alone, and the lineup can be called luxurious.

In fact, Tang Tian didn't think about looking for Lie Yang Tian to go together, but he seemed to be tracking down the unknown existence in the dark forest, which had gone deep into the snow-covered jungle, and he couldn't come for the time being. And Tang Tian also contacted Ruo Xi of the City of Hope, but she couldn't go, in her own words, to suppress the City of Hope and prevent the powerful mutant beasts from escaping after the radiation of the nuclear bomb.

As a reborn person, Liufeng has strange methods, so Tang Tian can't help but be so careful, who knows what means the other party has?

Outside the Sword Casting City, in a hidden valley in the distance, a dazzling light suddenly lit up under the ice and snow, and then a mirror like water waves appeared, Tang Tian stepped out, followed by Zhao Daniu and a few people.

"After entering the city, let's contact Xiao Chen and them first, only they may know where the flowing wind is, before that, we try not to cause any trouble, remember", instructed them again, Tang Tian took a few people and set off towards Sword Casting City.

It can be said that in order to kill Liufeng, Tang Tian can be said to have done enough homework, if he can't kill him in this way, then there is really no way.

When Tang Tian and the others rushed towards Sword Casting City, they suddenly stopped halfway to look at Xiangxia, and on the ice and snow ground below, a battle was going on at this time.

Ang ......, an earth-shattering dragon roared, and a hundred-meter-long dragon of light and shadow roared, dancing wildly, and where it passed, a group of people wearing swordsman's robes were suddenly killed.

"You guys go quickly, I'll stop them", one of them shouted, Tang Tian remembered this voice, but it was Sun Sheng who led him by, but he didn't expect that they were being chased and killed at this time.

"Eighteen Palms of the Dragon? Interesting, has one of the hall masters in this martial arts alliance mastered a set of second-order skills?" Tang Tian said to himself, after all, the other party had helped him, so he wanted to go and help.

But at this moment, the people on the side of Sword Casting City immediately put on a set of jianzhen, confirming that Tang Tian had seen the Beidou jianzhen at the beginning, a sharp and waveless brilliant sword light penetrated the heavens and the earth, the snow was as bright as a shining crystal, and in a flash, the ground was cut out of a long ditch, and Sun Sheng's punching action was also frozen.

"Hall Master ......", the people he brought screamed, Sun Sheng was already alive and dead, at this juncture, the Sword Casting City side once again had a few sword lights, the snow was just sprayed with blood, and the people brought by Sun Sheng were almost killed and injured.

Everything happened so fast, so fast that Tang Tian didn't even have time to save people, when a fragrant plum blossom harvested the people on the side of Sword Casting City, Tang Tian and they rushed to the battlefield, but even if he killed the people of Sword Casting City, he couldn't save Sun Sheng and them.

"There is still a living mouth here", the careful Zhao Yue'er found that among the more than ten people in Sun Sheng's party, there were still people who did not die, but they were the youngest Xiaoduozi.

After some treatment, Xiao Duozi saved his life, but when he saw all the dead people, he cried bitterly, "Thank you for the life-saving grace of the eldest brother, Xiao Duozi will remember it in my heart, I have to go back and report this matter to the alliance leader, and your great kindness and great virtue will be repaid later."

After some persuasion to no avail, Xiao Duozi took away the ashes of Sun Sheng and others.

"Alas, there are too many variables at this time, no one knows when they will die in the hands of whom, Sun Sheng is not bad, but it's a pity that ......", Tang Tian shook his head and sighed, and left here.

He didn't know that the people of Sword Casting City were going to kill them, it was not something he could manage, but Xiao Duozi was gone, and the Martial Arts Alliance and Sword Casting City were going to cause trouble again.

Sword Forge City was no different from a few days ago, as if that earth-shattering news had not affected it in any way, and people were still shuttling back and forth to the arena.

However, Lin Tian and Zhao Daniu, who saw today's giant sword for the first time, were the same as when Tang Tian saw it at the beginning, and they were all amazed, this giant sword was not something that people could use at all.

"Zhonghua Building? Boss or Hua Hero and Nameless? It's really weird, I really want to see these two people", when Tang Tian took Lin Tian and them to Zhonghua Building, Lin Tian showed great interest and said.

Tang Tian's arrival naturally quickly alarmed Hua Ying and Nameless, and after coming to the private room again, Hua Ying and Nameless were a little silent, obviously they all knew the earth-shattering changes two days ago, and they had not yet eased up.

"City Lord, is everything true? Mankind still has a future, and you have been able to cultivate new life", Hua Yingying asked with a look of hope as he looked at Tang Tian.

Tang Tian smiled bitterly: "Do you think it's possible? It's just to calm people's emotions."

"Is there really no way"? Nameless said bitterly.

Sighing, Tang Tian shook his head and said: "It's not that there is no hope, in fact, I already have a guess in my heart, but that's too unremarkable, I can't tell you yet, but I think it's not far from the truth."

"Castle Lord, what is it that prevents humans from being able to conceive life?" Lin Tian also asked.

"Now is not the time to say it, when the time is ripe, you will understand for yourself, although this is not a problem that cannot be solved, but it is too unrealistic at the moment", Tang Tian never said his guess.

Seeing Tang Tian's determined appearance, the others didn't ask any more...... (To be continued......)
