Hagakure Sakura Does Not Lament - Chapter 69

Clarence, a man married into the Murphy family, was disliked by all his in-laws, his wife, and was facing the possible fate of divorce.

All because he was an orphan and was not highly educated.

But in truth, he was actually the young master of one of the wealthiest families in the world.

And one day, he gained a strange ability.

A Russian economics expert had been making money through long-short strategies during the Russia-Ukraine war. Despite his economic success, he felt deep regret about Russia's historical mistakes. He wrote on his blog that “Russia has been on the wrong path since the 19th century,” critically analyzing Russia's history. Then, remarkably, he traveled back in time to 1891 and found himself in the body of Russian Crown Prince Nicholas II during his visit to Japan.

Zhang Lin, the king of Holy Light duel, was smeared by the team’s design and forced to withdraw from the online game professional league.
In order to return to the top, pick up the previous Summoner trumpet to fight against the Holy Light again, and perform the return of the king.
Summoner PK is the weakest? NO, everything is possible in Zhang Lin’s hands!
Play around with the guild, get the best equipment, and make beautiful MM…
Single P, Triple P, Group P, let the horses come over!
The bloody battle ignited the passion. Zhang Lin and his friends stepped over the mountains of corpses, and let tears and laughter witness Zhang Lin’s legendary online game life.
