What can we learn from '47 Meters Based on a True Story'?

When Fang Yuan was transmigrated into a world where Gu Breeder was the main profession, he found that he was not gifted. Not only that, the Gu in his body could cultivate on their own. [Your Iron Skin Gu has trained profoundly and has achieved the Gold-grade!] [Your Bloodthirsty Gu has begun to multiply itself into a swarm of Bloodthirsty Gus!] [Your Sunlight Gu has been absorbing the power of the sun for years and has gathered the Truth Flame of the Sun!] [Your Drunken Gu has evolved into a Soul-reaping Gu. Your control over it has risen by 100 folds!] [Your Flying Sword Gu was hurt in battle. Amid its desperation, it has evolved into a Sword God Gu!] “Heck, even Gu undergoes involution as well now?” Fang Yuan let out a sigh.

When Jiang Feng’s family mansion was forced to get demolished by the government for development, he was compensated with ten million. The moment he received the money, a system appeared. [Ding! Congratulations on activating the Divine-grade Choice System] Choice 1: Show off your ten million. Allow your relatives to mooch off you and send expensive wedding gifts to your girlfriend. Reward: Title – Good Person. Choice 2: Invest everything in Bitcoin for huge profits in the future. Reward: One hundred million. (One-time deal) Jiang Feng didn’t even hesitate to choose the second choice. He invested everything in Bitcoin and made a hundred million. However, he posted a different story online. “I lost everything in cryptocurrency. I’ll have to start all over again.” The moment the post went online, all sorts of demons and devils appeared. From that day onwards, Jiang Feng finally saw the true nature of humans.

Chen Gou transmigrates to the Blue Wave World, where evil spirits have invaded. All kinds of monsters that humans have previously imagined—Strigoi, aliens, spirits, the undead, zombies, demons, monsters—have appeared in this world. Humans awaken their magic and become Awakeners, who fight with their magic skills. After awakening, Chen Gou gets an innate skill called True Summoning. It allows him to summon a Battle Guardian to aid him in his battles. Just like Awakeners, his summons can learn skills. Chen Gou embarks on a journey to different abysses to gather information about them and eliminate evil spirits. What skills would his summons be able to learn along the journey?
