Complete the four Blue Jewels. Place them in the altars on your farm to unlock the Buggy and Ranch in the storage area.
Crop Value Increase
A set of Orange, Purple or Green Jewels in a field adds 20% to the shipping value of any crop grown within their influence. Use the Mother's Touch to harvest crops to add another 10% to the shipping value.
Easy money
Wait until the doctor gives you your robot. Once you get it, make it take care of your crops and field for you while you are looking for wild things to collect. When you get your scale pack full, buy as many seeds as possible. Plant them all. When your plants can be harvested, do so. When done, put all of the contents in your scale pack in the shipping pod with the harvested crop. You should end up with a large sum of money.
Ranching Foresight
As soon as you purchase any animal from the World Ranch, you can go to Jonathan and speak to him to obtain the next Robot Animal Helper.
The animal you purchased does not need to have been delivered to the farm yet.
However, Jonathan will assume that you already have the animal in use and will proceed to tell you that he will send the next type of Automatic Animal, unlocking the option to purchase that type of animal from the World Farm.

Sad ending
When you wake up in year two screen shaking there's an earthquake and cutscene show up volcano is erupting and you got away with stone raft and dr.hope speak to you from nowhere and he said your chip is special and he said again go back into that day and everything go normal.
Tool Usage
You cannot cheat the game and use tools for no reason in Innocent Life Futuristic Harvest Moon; however, you exploit the system and use tools after certain tasks or activities are done.
For the watering can just till a square of soil and you can water that square once with the can. Note that the item ''strange moss'' prevents you from watering the affected square daily, so use this exploit on squares that are virgin.
As for the hammer and hoe, there is an exploit to use them on a single square so long as your character has PP to spare. Use the hoe to till a square then use the hammer to ''untill'' the square. Go back to using the hoe and repeat. All this can be repeated so long as you want to expend PP.
Watering Can
To obtain a better Watering Can early in the game, simply water every tilled square (with or without crops on them) until your character reaches Level 2. Speak to Masami afterwards and she will give you a Weird Watering Can that can water three squares at a time.
