MTL - Unlimited Machine War - Chapter 2768 Pre-war mobilization

Luo Yi, a high school dropout in his original world, was isekai’d into the world of the Witcher 3. Starting out as a weak boy named Roy in the village of Kaer, Lower Posada, he was determined to grow stronger, no matter what it took. The first step toward becoming a legend was to kill. And his first kill was… a rooster. ‘You gain 1 EXP.’ Of course, Roy had his own cheat system like all the other isekai protagonists. His first step to becoming a legend started now…

Perhaps it is the choice of fate. As a senior otaku, Qian Lingfeng got the “steel shell system”. However, when he swept the world with the system, became a local rich man, made all kinds of beautiful women, opened a harem, and realized the ultimate fantasy of thousands of otaku, he found that things seemed far from simple!
When the end comes, biochemical zombies suddenly come down, fierce beasts are in power, bloodthirsty zerg roam to kill the world, and human lives are comparable to dirt. Where will weak human beings go in this world? Is humanity going to be extinct? Or … can an otaku save the fate of the human race?

A game descended upon reality. A dimensional gate opened.

Beasts from the dungeon stared out intently. The human world was in danger.

Fortunately, the whole world awakened to new powers. During their coming-of-age ceremony, everyone had the chance of obtaining new jobs and abilities, such as Knight, Mage and Archer.

Those who awakened battle job classes would become heroes.

Those who awakened other job classes would serve in logistics or become cannon fodder.

Lin Sen awakened the Farmer job class, which was acknowledged as the weakest job class. Aside from harvesting crops and caring for flowers, he would rear cattle and sheep.

Fortunately, he awakened the God-tier Farm System.

Lin Sen decided to plant crops on his own!

On the first day of planting crops, he obtained the seed of the ancient Tree of Life.

Then, he obtained the Nine Leaf Sword Grass, God Binding Vines, Corpse Stench Demonic Vine…Various god-tier plants appeared and shocked the world.

Other people exclaimed, “What job class is this? He can actually clear the final dungeon solo!”

Lin Sen claimed, “I am just an ordinary farmer.”
