At the beginning, after the people of the Cao family escaped from the mountain city, they all fled into the Tianduan Mountain Range.

The ancestor of the Cao family and the patriarch of the Cao family contained them together one by one, and then found a place to live in the depths of the Tianduan Mountain Range, and began a difficult and dangerous escape life.

After the order of the Demon Clan Alliance to order the people of the Demon Clan to capture the human warriors on a large scale was conveyed, the entire Cao family was suddenly surrounded by countless demon beasts at noon one day.

The people of the Cao family were all shocked and desperate, thinking that their Cao family might be wiped out by the demon clan this time.

But to the surprise of all the people of the Cao family, the demon clan did not slaughter the Cao family, but asked the people of the Cao family if they were willing to surrender.

The patriarch of the Cao family and the ancestor of the Cao family hurriedly replied that they were willing to surrender.

The ancestor of the Cao family also told the people of the demon clan about the reason why their Cao family was cornered by the Great Xia Kingdom and hid in the Tianduan Mountain Range.

The people of the demon clan were overjoyed after hearing this, and very politely and friendly invited the people of the Cao family to the Terran traitor camp set up by the demon clan in the mortal world.

In the traitor camp, one of the demon emperors of the demon clan told these captured Terran people who were willing to surrender to the demon clan the reason for capturing them, and then asked these terran traitors to tell the various situations of the Terran, including what happened to the catastrophe of the Terran, why the Terran targeted the demon clan, the deployment of the Terran clan, etc., especially about Li Yuan's situation.

This demon emperor also promised these human traitors that as long as these people sincerely contribute to the demon clan, the demon clan will reward the secret books of the exercises, the elixir spiritual weapons, the spirit stones and spiritual materials according to their respective contributions, and ask the advanced human traitors to teach them the internal martial arts, martial arts, as well as food and beauties, and even hold important positions in the demon clan!

In order to allow these traitors to work for the demon clan with all their hearts, the demon clan also organized a large number of fox clans, Meizu clans, snake clans, elf clans and other clans, cultivating into demon beasts above the seventh level that can transform into human form, let them transform into beautiful women or beautiful men, and give them to these human traitors, charm these people, make these people lose their hearts and nature, and die for the demon clan.

Of course, in addition to using various temptations and brainwashing these traitors, the demon clan also announced cruel punishments:

For those traitors who don't really work for the demon clan, the demon clan will not only execute these people in the most cruel way, but also try their best to arrest or execute all the relatives and family members of these people.

For those who escape, or pretend to be running errands for the demon clan in the human area, and take the opportunity to escape, the demon clan will capture them at any cost, or execute them, and will capture or execute all the relatives and family members of these people at any cost!

The people of the Cao family were invited to the camp of the Terran traitors, and after they heard the reason why the Martial Emperor invited them to the camp of the Terran traitors, and learned that the Demon Clan urgently needed to know about Li Yuan's situation, the ancestor and patriarch of the Cao family immediately reported to the Martial Emperor, saying that they were people from the mountain city, and they were in the same city as Li Yuan, and they knew the situation of Li Yuan and the Li family in great detail.

Then the old clan and patriarch of the Cao family told the demon clan Emperor Martial Emperor about Li Yuan's situation in the mountain city, as well as the situation in the county town and the imperial city later.

After hearing this, this Martial Emperor immediately realized that this news was very important, and then he decided on the spot to send a few Yun Peng, who had cultivated to the seventh and eighth levels, to transport some Cao family members, such as the Cao family patriarch and the ancestor of the Cao family, to the headquarters of the Demon Clan Alliance.

Li Dalin and Cao Tao were also sent to the headquarters of the Demon Alliance by the Demon Clan for the same reason.

At the headquarters of the Demon Alliance, the ancestor of the Cao family, the patriarch and others met Cao Tao. The people of the Cao family were all full of emotion:

The family suffered, everyone escaped death, hidden in the Tianduan Mountain Range, and surrounded by the demon clan, the situation of death was originally determined again, but it turned out to be a death escape, and it was really lucky to be able to meet their family genius!

Originally, Cao Tao was the hope of the entire Cao family, but after the Imperial City incident, Cao Tao had no news, and everyone didn't know Cao Tao's situation, or even whether Cao Tao was alive or dead, so they were very worried.

Now that I have met Cao Tao, I know that he is not only safe and sound, but also that his cultivation has reached the fifth level of martial arts!

It is much better for him to come to the Demon Clan than he is in the Terran Clan, because in the Terran Clan, there is Li Yuan, and all the people in their Cao family have no place to stay.

Ao Tai, the leader of the Demon Clan Alliance and the patriarch of the Dragon Clan, personally met with the ancestor of the Cao family, the patriarch, Cao Tao, and Li Dalin, and listened to them introduce the situation about Li Yuan in detail.

Ao Tai praised the three members of the Cao family and Li Dalin for their contributions to the demon clan, and promised to reward the four of them heavily.

The three members of the Cao family and Li Dalin hurriedly kowtowed to Ao Tai to thank him, and the ancestor of the Cao family swore an oath and cursed, saying that the entire Cao family must be desperate to take refuge in the demon clan, and for the sake of the demon clan, they are willing to go up the knife mountain, go down to the sea of fire, break their bones, smear their liver and brains, and never give up.

Li Dalin also hurriedly swore a curse to show such loyalty.

Ao Tai looked at Li Dalin and the people of the Cao family, one offended Li Yuan, and there was no place for them in the human race; second, these people were all greedy for life and afraid of death, and regarded life as the most important thing, unlike some people of the human race who had integrity and would rather die than give in, so he was very happy and decided to reuse these people.

So, Ao Tai gave each of them a copy of the elixir spirit weapon collected from the Terrans, and asked them to serve as the captains of the Terran traitor camps.

Ao Tai saw that Cao Tao's martial arts cultivation talent was excellent, in order to win over the Cao family to work harder for the demon clan and be more capable of working for the demon clan, he decided to use the Dragon Clan's Daigo empowerment technique to pour into Cao Tao's body the skills of the two Martial Emperors who were dying of life.

Then Ao Tai used the secret technique of the dragon clan to hide Cao Tao's cultivation as a martial artist level 5.

Then he ordered the old clan and the patriarch of the Cao family to select a few people from the Cao family to follow Cao Tao to the Terran area, waiting for an opportunity to assassinate Li Yuan, and jointly find out the situation of the Terran, especially about the Terran's teleportation array, Void Breaking Knife, Void Breaking Array, etc., and waiting for the opportunity to destroy the various facilities and deployments of the Terran.

The ancestor of the Cao family saw that Ao Tai had suddenly promoted Cao Tao's cultivation to Wuzun, and he was ecstatic in his heart:

Although it is somewhat dangerous to send Cao Tao to the Terran area to assassinate Li Yuan and engage in sabotage, one Cao Tao only shows the cultivation of the fifth level of a martial artist, and secondly, Cao Tao is just a child, and it is impossible for everyone to pay attention to and guard against him.

As long as Cao Tao was well prepared, assassinated Li Yuan, or destroyed it, with his martial arts cultivation, it was still easy to escape.

Of course, before Cao Tao left, he had to explain to him clearly, no matter whether he assassinated Li Yuan or sabotage, he had to make sure that nothing went wrong before he started! His own life was the most important, and he must give priority to saving his life at any time. I'd rather not do it than lose my life.
