Yesterday, I tried my hand at making a Turtle Ship game using Arena.ai, developed at the University of California, Berkeley. It’s similar to the Galaga game from the 1980s. We live in a world where anyone can do something like this with just a few taps of their fingers.

존버는 영어식으로 바꿔 Life often seems to offer only two choices: fight or flee. But victory usually belongs to those who know how to wait—to prepare, endure hardship, and build the wisdom and relationships needed for lasting prosperity. Waiting means holding the line enduring to the very end.

Good rarely breeds more good. Evil never breaks its circle, only grows— unlike good, it never turns back to good. The good rise at last, though the wait is bitter. The wicked always win, but heaven closes the ledger. Hope lives in good hearts. Laugh on, wicked one—eternity is yours.

Every time I get rid of a book, the burden on my mind lightens. Following last week, I pulled out more books again. This time, I decided to recycle them. There are many books in the world, but some of them are of no use to anyone. This week, I turned those books into scrap paper.

From spring through fall, my weekends are always fully booked. I nurture life, let it die, and harvest the fruits of my labor. Today, I encountered several flowers that had bloomed pitifully. I also saw the basil, which always gives off a refined fragrance, taking root.

It’s been over six months since I started researching games related to Admiral Yi Sun-sin. I’m still struggling because I don’t know enough. The latest game I discovered is [Portless: Little Cannon].

Winning in the process of winning is harder and more beautiful than simply winning. That’s what comes to mind as I watch the game.

It is a famous mountain in Korea. Its name is Ma i san. It is written that way in Chinese characters because it resembles a horse’s ear. It is a uniquely bizarre rocky mountain, even by Korean standards. Whenever I visit, I feel like offering a prayer to the heavens.

While researching games about Admiral Yi Sun-sin, I discovered Imjin War: Joseon’s Counterattack, released on April 28—his birth anniversary. The developer has spent 30 years focused on Yi Sun-sin and the Imjin War. That kind of dedication is rare.

I saw the first lotus flower of this spring the day before yesterday. In Korea, lotus flowers are mostly associated with the Buddha. My friend’s father has passed away, and as I came to pay my respects, Lotus flower came to mind once again. May he rest in peace in the Pure Land.

I’ve been researching games related to Admiral Yi Sun-sin for several months now. He appears in games from Korea, Japan, and the West. I also downloaded and played [Imjin War: Joseon’s Counterattack], which was released yesterday. You should give that game a try. imjinwar.joycity.com

In the December 1992 issue of the gaming magazine My Com, there was a turtle ship game code written in BASIC. Not knowing much about programming, I used AI to understand the content, turtleship.netlify.app

This painting is titled The Majesty of the Turtle Ship by artist Park Byung-ho. Park is not a well-known artist. There are very few oil paintings or folk art pieces related to Admiral Yi Sun-sin from the 2000s, or even from earlier periods. This is one of those rare exceptions.

Korea Hero Admiral Yi Sun-sin's poem. <The Song of Hansando> On the bright night of Hansan Island's moon, I sit alone in a pavilion. Holding a long sword by my side, I feel a deep, deep sorrow. As the sound of a flute, From somewhere nearby breaks my heart.

Last week, I used AI to upgrade the BASIC code for the "Geobukseon" game from a 1990s gaming magazine and created a new version of the game. I failed to create the Geobukseon icon, so I just substituted a regular turtle instead.

Admiral Yi Sun-sin did not spend all his time fighting battles. Nor did he spend all his time training. In The War Diary, on rainy days or during occasional moments of leisure, board games and the game *Jongjeongdo* are mentioned.

I am continuing my research on Admiral Yi Sun-sin and the games that symbolize him. While studying Yi Sun-sin-related texts from various Joseon Dynasty documents is important, I found that many of them were either nearly identical or contained fabricated or altered facts.

suno.com/s/jGI0fD22dt... After seeing the version of "Arirang" recorded by Dr. Homer Hulbert at his exhibition yesterday, I used Claude and Sunno AI to create a "Space Arirang" for the era of space travel. "Arirang" holds a special place in my youth, so it feels different to me.

These are the garments worn by kings and queens during the Joseon Dynasty in Korea. They embody the Korean spirit. They differ from those of China and Japan, which are also part of East Asia. They are on display at the National Palace Museum of Korea in Seoul.

Has the Tower of Babel been completed through X’s automatic translation? Or is it rather the collapsed Tower of Babel that is allowing diversity to flourish? Being able to read the world’s many languages is like a completed Tower of Babel.

In Admiral Yi Sun-sin’s diary, on April 5, 1592 (Gregorian calendar), it mentions a “flower rain” (花雨, hwa-u). It was precisely this time of year. He rode his horse through the flower rain to inspect the area.

The magnolias, still elegant. In a corner beneath those magnolias. The remnants that sang of spring’s passing with sorrow. The queen of spring and the flowers welcoming spring—a fleeting harmony. The gentle dance of early spring, sung in another place, the fresh new shoots of the willow.

I used VidMuse—which someone recommended to me—to create a music video for [The Crooked Tree], a song I made earlier with Suno AI. Since it was my first time trying this, it turned out to be a horrorㅃ movie version, which wasn’t what I intenㅂded.

This is [The Naval Battle of Admiral Yi Sun-sin], painted by Yoon Se-hee, a contemporary Korean painter of folk customs. The flames emerging from the Turtle Ship are likely caused by cannons fired from the dragon’s head on the ship.

While looking into the history of computer games, I realized there are many naval battle games. The game shown in the attached image, *Admiral: Sea Battles*, is Ukraine’s first commercial game. It was developed by Studio Meridian’93 in 1993, but was released simultaneously in the United States

[A Flower That Resembles My Mother] Before the forsythia bloomed, that flower always opened its buds first. Even before the azaleas. In the south, even before the delicate petals of the plum blossoms. Some say it is a symbol of integrity. Enduring the winter, it formed fluffy buds.

In the *Zhuangzi*, there is a similar saying: “A crooked tree lasts a thousand years.” This offers some comfort. But if you think about it, that is a rare case where a crooked tree has survived for so long.

I finally got a chance today to check the back cover of the English edition box for [Age of Empires II: The Conquerors], which I posted yesterday. Since the original was the English edition, I was worried that the scene of the Turtle Ship might be missing from the back cover.

The game *Age of Empires II* is special. If you look closely at the box or CD for the second installment, you’ll see three figures. One of them is a Japanese warrior (samurai). The game’s setting is Japan, and the samurai is a figure familiar to Westerners.

Thank you. I am grateful. There has always been a difference between the two. The words spoken from the heart are in pure Korean, while the words spoken in a formal manner are in Sino-Korean. I didn’t really notice it, but they were always different. Thank you.

In the 60s and 80s, barbershops often displayed paintings known as "barbershop paintings." These were copies of Millet's paintings, scenes of a mother pig with her piglets, or depictions of Kㅡorean rural landscapes or Western scenery painted on the back of glass, viewed from the front.
