"Can't Awaken Bloodline" 

Jake's grandma entered the teleportal and immediately disappeared within seconds. 

No one saw the teleportal and even if they did, they couldn't enter the carefully crafted teleportal at all. 

Even Jake's teleportal might not be as good as this one in terms of security because the blood clan personally used their precious blood to craft this portal! 

When Jake's grandma came out of the Blood Teleportal, she appeared right at the post for visitors in the Blood Clan's capital city. 

Those who wanted to go out of the kingdom or enter the kingdom had to pass through this post for a thorough inspection. 

For the blood clan to be able to hide for a thousand year until no other races knew about their condition, their security measure was definitely top-notch. 

Their citizens could rarely come out to the surface and even if they could, only those with a lot of impure blood could have this privilege.
