The frightening thing is that these spiritual trees exist in Lin Yi's own space, and Lin Yi absorbs spiritual power very quickly.
Absorbing through the spirit tree in the space, one day can be worth a hundred days of cultivation with the spirit tree outside.
Therefore, Lin Yi doesn't need any spiritual tree group at all, he is the spiritual tree group himself.
Lin Yi had already absorbed a lot of spiritual power after just practicing for one night.
Now, the upper limit of Lin Yi's cultivation is no longer the spirit tree, but the fusion speed of his own dantian. If this point can be broken through, Lin Yi's cultivation speed may break through the sky and reach a sky-defying level.
After one night, all the spiritual power that Lin Yi had consumed was replenished.
Afterwards, Lin Yi continued on his way and headed straight to the north.
After driving for about a day, Lin Yi didn't stop for a moment. He met more and more people on the wasteland, and there were only one car coming and going in a while, which was very bustling.
Finally, a city appeared in front of him.
As expected, it was Fearless City.
"Finally it's almost here!" Lin Yi heaved a sigh of relief, his face was extremely solemn, he had to find the wolf demon when he came on this adventure.
Only by finding the wolf demon can we find out the whereabouts of Nanyan. If the wolf demon has really dedicated Nanyan to the emperor of the Heavenly Demon Empire, it will be really difficult to handle.
Even if Lin Yi had a powerful army of phantoms, it was impossible for him to forcibly snatch people out of the palace of the Heavenly Demon Empire.
There are so many masters in the Heavenly Demon Empire, Lin Yi can feel this even after he has just been in the Heavenly Demon Realm for a few days.
Almost everyone in the Heavenly Demon Realm can practice cultivation, that is to say, everyone is a practitioner and has some fighting skills.
Practitioners at the Linghuang level are already very rare in other domains, even top-notch practitioners.
But in the Heavenly Demon Realm, they are everywhere.
"Boy, stop, leave all your treasures and money behind!"
Just as Lin Yi was about to speed up and go on his way, more than a dozen big men jumped out beside him, blocking Lin Yi's way.
Lin Yi glanced at it, and the opponents were all of the cultivation level of the Heavenly Rank Linghuang.
This group of big men stared at Lin Yi covetously, like beasts.
Lin Yi appeared here alone, and looked very easy to bully. Obviously, these big men would not take Lin Yi seriously.
"Boy, what do you look at? We are the bandits here. If you don't obey, we will cut you off!" As he spoke, a big man stepped forward and waved the knife in his hand.
It turned out that it was a group of robbers.
On this avenue, there are many businessmen passing by, and it is not surprising that there are robbers.
However, Lin Yi, a young man, seemed a little strange.
Lin Yi frowned, "I have nothing, you robbed the wrong person!"
With that said, Lin Yi continued to walk forward.
"Boy, let's search the body, otherwise we will never leave!"
Knives with a cold light came to Lin Yi's body.
Lin Yi chuckled, "Okay, come here!"
With that said, Lin Yi opened his arms with a calm look.
The dozen or so big men quickly surrounded him, but just as the leader was about to reach out to search Lin Yi, a cold light burst out from Lin Yi's body.
No one knew how Lin Yi drew his sword in such a short period of time, because the speed was too fast.
Everyone saw only a flash of red light before their eyes, and the big man's head had already flown out.
In Lin Yi's hands, the giant sword was like a devil from hell.
"What... what!"
"Too...too fast!"
"This kid!"
A dozen big men were all shocked by Lin Yi's move.
Killing a Heaven Rank Spirit Emperor with one strike, this strength is a bit terrifying.
With Lin Yi's murderous intentions, he would definitely not show mercy. The giant sword in his hand was entangled with three giant dragons, and blasted out.
In an instant, two more heavenly spirit emperors died under Lin Yi's sword, and they couldn't even see Lin Yi's moves clearly.
Today, Lin Yi's fighting power is already superb in the spirit emperor realm, even a group of heavenly spirit emperors are completely ignored.
"This kid is a monster!"
"Everyone run away!"
The few remaining robbers finally came to their senses and fled into the distance in fear.
It's a pity that they didn't even take a few steps before they were pierced through the heart by Lin Yi's sword energy, killing seven or eight people in an instant.
For Lin Yi, killing people was a breeze.
The explosive power at this moment is really terrifying.
There were more than a dozen corpses lying on the ground, and everything happened in an instant.
Lin Yi put away the giant sword, and the murderous aura on his body gradually disappeared.
He is now in a bad mood because of Nanyan's affairs, and this group of people came to trouble him, and they are simply asking for their own death.
After killing the robbers, Lin Yi continued to rush forward, and soon stepped into the gate of the Fearless City.
Although the entire Fearless City is not too big, it is still very prosperous, because there are thousands of miles of wasteland nearby, and there is only this city.
Many businessmen and practitioners would choose to stay in the Fearless City.
So on the streets of Fearless City, there are people selling everything, and it is very lively.
After Lin Yi walked for a while, he came to the City Lord's Mansion of Fearless City.
The entire City Lord's Mansion is a heavily defended place in Wuwei City, and there are guards patrolling all around. Even in the mansion, there are a large number of masters.
It is almost impossible to sneak into the city lord's mansion without knowing the ghosts.
Lin Yi is also very worried. It seems that the only way is to go in directly, but this way is too risky.
One is that there are many masters in the city lord's mansion, and there are also powerful spiritual masters sitting in the town. Even if Lin Yi has an army of ghosts, there will definitely be a lot of troubles. The wolf demon is likely to escape. Alarming the high level of the Heavenly Demon Empire, Nanyan will be in danger at that time.
Therefore, Lin Yi had to think of a way to catch the wolf demon without anyone noticing.
After Lin Yi calmed down, he didn't act impulsively. Instead, he wandered around the city lord's mansion for a few days, observing his every move.
Finally, Lin Yi waited for an opportunity.
Today, the movement of the City Lord's Mansion suddenly became abnormal. All the guards were busy with something and strengthened their defenses in the mansion.
The tall horses were also suddenly transported outside the city lord's mansion. Judging from this posture, it seemed that they were about to go out for a battle.
Lin Yi inquired about the news nearby, and learned from the passing merchants that there was a rebellion in a town below the Fearless City.
The local rebels massacred the soldiers and guarding generals of the Heavenly Demon Empire, causing great commotion.
Since it was a rebellion, Fearless City would naturally be in charge, and the wolf demon had only been in office for a few days, so he decided to step down and go out in person to wipe out the rebellion. The movement of the City Lord's Mansion is preparing for this battle.
