The Immortal Alchemist Returns

The Feng Family of Maple Falling Town in the Divine Continent was known as an idiotic family with some members who struggled to comprehend even the most basic knowledge. 
One day, word got out that the Feng family had obtained a treasured sword. Several families joined hands to destroy the Feng family and steal the treasured sword. During that time, the young Feng Zhentian escaped with great difficulty until he fell down a valley and found a Netherworld fruit and the Chaos Cauldron. This fruit and cauldron turned him from being an idiot into becoming the number one Alchemy Emperor of the Divine Martial Continent, the Wind Monarch.
However, even with his high status and strength, he was still betrayed and killed by those who coveted his Chaos Cauldron.
After dying, he surprisingly woke up in class, back when he was only thirteen years old and known as the class idiot. Although this situation gave him a great deal of shock, he saw it as the best opportunity for him to protect his family and loved ones from the chaos that’s about to happen a year from now.
