"This Ars, then you need to know the position of the sun at all times, right?"
That's right. And if we lose them, we must be able to find them again.
"I see."
Jin was glad that he had come to 700672 for advice.
"And then there's the autopilot. It's not good if you can't control it while you are sleeping or in a situation where you can't take your hands off the controls.
That was also a good point.
"We need to take into account the possibility of weightless ...... conditions," he said.
"So the equipment is basically fixed, right?"
"Yes."
Some magnets may be used for some objects," added 700672.
Jin nodded as he was told that it is necessary not only to rely on barriers but also to detect them in advance, since hitting cosmic dust or meteorites during high-speed flights in space can cause a lot of damage.
"We need something like an objective radar, don't we?"
"Yes. It may be difficult, but yes. And it is better to destroy large objects than to avoid them, so it would be good to have such a weapon as well.
"Ah, yes."
There are magic cannons and laser cannons, but no explosive weapons.
"<> is used to create bombs, mana bombs,...... or missiles with warheads,......."
Jin's motivation only increases.
He was also told that if they were to land on the moon or some other unknown celestial body to investigate, it would be useful to have a special vehicle.
"There are some things you won't be able to find from the sky alone," he said.
"Yes, sir."
We could use a Capricorn 1 or a Tortoise, but we would need a vehicle that could operate in a vacuum. At the same time, we need a reconnaissance plane.
And, more importantly, we need a lifeboat to get us out of here," said 700672.
"Needless to say, it is dark in space. There should be enough light on board."
Other advice included designing the ship with sufficient margins for lifelines - water, food, and air (oxygen) - and finally, "If you're stuck, you can always go back to the ship,
Finally, he told us, "If you are at a loss, you can always visit us.
Jin returned to Horai Island.
Jin returned to Horai Island. He was satisfied that it had been a very meaningful time.

Welcome back.
When Jin returned to Horai Island, he was welcomed by Elsa.
Lately, Erza has been spending her mornings in the village of Kaina, teaching children with Meane and helping Sally at the clinic.
"I'm home."
"The old man told me you went to the 700672?"
"Yes. I got some advice from him.
Jin then explained the advice he had received from No. 700672 for the construction of the spaceship.
"As always, I appreciate his advice. Can I ask you a question too, ......?"
Of course.
"If you build a first aid room or an infirmary, make sure there's another system for air conditioning, gravity, lights, etc."
"Sure."
Jin agrees with me that it is absolutely necessary to improve the reliability of such life-saving facilities.
"...... so I think it would be a good idea to ask the members of the family about it as well."
