Since the beginning of Dr. Stone begins, we are amazed by the various discoveries that Senku has made in a world that goes back to the stone age. As a super genius, Senku plans to revive civilization by recreating everything in the modern world.

On this occasion, the writer would like to discuss 10 most useful inventions that Senku Ishigami has ever made in Dr. Stone. Let’s see the discussion below!

1. Katana

Before meeting the residents of Ishigami village, Senku had already created a crossbow. Only Tsukasa could stop the weapon when it was fired by Senku. Since then Senku started thinking about creating a more powerful weapon.

Senku refers to the katana as the strongest type of sword that can not only be used to defend, but also to cut and kill his opponent. Senku made the katana more to frighten the opponent than to kill. This is because Senku himself doesn't want bloodshed.

2. Antibiotics

In order to develop and save civilization, someone in that era must be able to find ways to prevent or treat diseases that attack humans. This is because disease is the biggest problem that reduces the human population. From there Senku thought of creating antibiotics.

It was a sulfa drug that Senku found from chemicals and minerals that can be found around Ishigami village. By discovering drugs, Senku already has an advantage over the rival kingdom led by Tsukasa as those people rely solely on sports to prolong their lives.

3. Gun Powder

One of the reasons why Tsukasa was so afraid of Senku was gunpowder. This was because the existence of weapons could make all humans superior. Firearms or pistols made from gunpowder can outperform extraordinary physical strength like Tsukasa.

That was Senku's most important discovery when he started to become Tsukasa's enemy. Even though he can find it, Senku doesn't want to make a firearm like a gun because that would cause bloodshed. Precisely Senku wants to revive all humans from petrification.

4. Steam Car

The steam car is a large weapon used by the Science Kingdom against the Tsukasa Kingdom seen in season two. The power of the Tsukasa Kingdom motivated Senku to create the best combat car that could be created in this stone age.

This tank-shaped car serves to break into Chrome's prison. One of the goals of the gunpowder that Senku made was to strengthen this vehicle so that it would be able to deal with Tsukasa by firing cannons.

5. Power Stations

Electricity is one of the main needs of humans in modern times. In this day and age, it is impossible for us to live without electricity. Senku also decided to make a power plant as a first step to revive civilization. With this too, life in Ishigami village becomes easier.

Not only can they get light at night, residents can also get many other benefits. Senku also makes batteries to be used for various technologies that he will make later.

6. Softlenses

Sight is one of the greatest gifts that mankind has. Those who can't see won't be able to do much. As soon as Senku came to Ishigami village, some of the residents were myopic like Kinro and Suika. Senku was able to overcome this problem by inventing contact lenses.

With this, they could see clearly. Senku placed contact lenses onto the vegetable mask that Suika usually wore, while Kinro had glasses made for her so she could see clearly.

7. Cellphone

The more humans Senku resurrects, the more they will fight alongside them against Tsukasa. Because of that they need a means of communication when they are separated to look for certain materials or objects. Senku also thought of making a cell phone.

Initially he had the idea to make a smartphone, but that seemed impossible in the stone age. Senku also made a talkie walkie which works very well. Residents can communicate with each other, as well as Senku who exchange information with Chrome and the others.

8. Instant Ramen

The reason Senku doesn't attack Tsukasa in winter like snow is because food sources are hard to get. That would be a nightmare for the residents because they could starve to death if they weren't good at preparing food beforehand. Senku also thought about making ramen.

The reason Senku chose ramen is because this food can last longer than wild boar or fish. The villagers of Ishigami are very happy to be able to taste dishes as delicious as ramen.

9. Revival Fluid

One of Senku's greatest inventions that can save humanity is a revival fluid. This thing is able to revive humans from petrification. This is the key to reviving the modern world 3,800 years ago.

Nitric acid is this magical liquid that Senku can get in a cave. Unfortunately, Senku can no longer get the liquid after his cave was destroyed due to the fight against Tsukasa's group. Luckily Senku has raised the best people who can help him.

10. Ship

To be able to develop the civilization that Senku wants to revive, he has to go to other areas between islands that are impossible to reach on foot. That's why Senku decided to build a ship. He builds a ship with help from Ryusui Nanami, a genius who is able to make plans of sea ships and control them.

Together with Ryusui as the captain, Senku continues his noble goal of awakening humanity from petrification.
