21st century Goguryeo - Chapter 506 - Season 2 Book 20 Shadow of War - 4-4 Disputes

Xia Ling wanted to run, but no matter where she went, she could always see the devil king with a gentle and malicious look in his eyes. "Xia Xia, where are you running to? " [1v1, sweeter than ever ] "..." Text: Yan Luo Bai, "fast wear, flirt: Plan to save the fallen boss"

When he woke up, Yun Ting turned out to be Konoha’s new fourth Hokage.

What about the water gate?

Oh, he was looking at himself with envy and regret under the stage.

Looking at the time again, it is now at the end of the three wars, and there is only one year left before the Nine-Tails Rebellion.

Yun Ting suddenly panicked.

There is a great crisis of life and death outside, and an old man headed by three generations is taking power. This situation is very bad!

Do you want to become a short-lived Hokage like Minato?

Fortunately, Goldfinger arrived in time.

As long as Yun Ting’s Hokage reputation continues to increase, Wood Dun, Immortal Mode, Flying Thunder God, etc. can be exchanged.

So…a year later.

“Kiuwei, you finally appeared! Eat my immortal method, wood escape, thousands of hands, turn into a Buddha on the top!”

Or will he succumb into a conspiracy lurking within the country's borders?

Gripes have their origins and debts have their creditors. We haven’t crossed each other in days past or present, nor formed any grudges. I am but duty-bound to carry this out, so apologies in advance!

In his past life, Yang Chen was a gentle person who was oppressed for his whole life.

Now that he’s reborn, he chose to become an executioner and severs ties and grudges with his executioner’s blade, killing all that climb onto the Immortal Executioner’s Platform!

Heads will roll! Humans’ in the human realm, demons’ in the demon realm, devils’ in the devil realm and immortals’ in the immortal realm!
