Five hundred tons!

A thousand tons!

Five thousand tons!

It didn't stop until it reached thirteen thousand tons.

Just one engine reached a thrust of 13,000 tons.

That's amazing, isn't it?

You must know that one Xingxinglong device can be connected to up to twenty engines.

In other words, the maximum thrust of a single Xinglong device will exceed 260,000 tons.

Two units are 540,000 tons.

The key is that these forces can propel more than 500,000 tons of warships off the earth.

Think about it, and know how scary it would be.

Su Han was naturally very satisfied.

Su Han said: "That's right, Shenlong! How much tonnage do you think is appropriate for our first battleship to build? ”

Shenlong said: "If you calculate it by the thrust of the Thunder Dragon A engine. It is possible to build a 250,000-ton warship with a single core or a 500,000-ton warship with a double core. ”

Su Han said: "If it's 500,000 tons!" How many people can it carry? ”

Shenlong said: "Theoretically, there should be no more than three thousand!" ”

"Isn't it!" Su Han was speechless when he heard this, and said, "You mean that a 500,000-ton spaceship can only accommodate 3,000 people?" You've miscalculated! ”

Shenlong said: "There should be no mistake!" The main thing is that the human body structure cannot live in a state of gravity for a long time. If you want not to affect the health of the crew, you must create an artificial gravity zone. Then the artificial gravity zone is destined not to be able to carry too many crews. As for other areas, they can only be used as carrying materials, and although the capacity is large, they are not effective capacity. ”

Su Han certainly knows the importance of artificial gravity zones.

After all, humans are born to live in a place where there is gravity.

If there is no gravity, all kinds of cardiovascular problems, immunity problems, and endocrine problems will appear one after another, and I am afraid that before I fly to the next star, I will be wiped out.

Su Han said: "But this spaceship only carries 3,000 people!" Even if you build 100 ships, it's only 300,000 people! Isn't it a bit shabby to take this person into the universe? ”

Shenlong said: "The best way is to build a mothership that is large enough. The mothership can be divided into a rest area and a work area. The crew can take turns to work in the work area, so that the gravity area can be guaranteed to live for enough time, and naturally more people can be accommodated. "That's a solution!" Su Han suddenly remembered something and said, "That's right! How fast can the engines of the Twin Dragon device accelerate a 500,000-ton warship? ”

Shenlong said: "In the state of working fluid! About 10,000 tons of helium-3 can accelerate to 30 percent of the speed of light. ”

"Ten thousand tons! What are you kidding? Su Han was speechless when he heard this. While 30 percent of the speed of light is already impressive, it requires 10,000 tons of helium-3. You must know that now he has put tens of thousands of mining dragon robots on the moon.

It only produces a few hundred tons of helium-3 a year.

A spaceship with 3,000 people costs 10,000 tons.

Then a hundred!

Wouldn't it cost a million tons of helium-3 from time to time!

This is still an acceleration!

Wouldn't it still take a million tons to slow down?

Two million tons of helium-three!

Thinking of this, Su Han also felt a chill on the back of his neck!

Su Han said: "Divine Dragon! Did you know? A hundred warships, two million tons of helium-three are needed for acceleration and deceleration? ”

Shenlong said: "Of course I know! I'm just answering my boss's questions truthfully. ”

Su Han said: "Then you should also know!" There's no way I'm going to get two million tons of helium-three? Even if I smash the moon, there won't be so many helium-threes! ”

Shenlong said: "Of course, two million tons of helium-three is unrealistic!" The best way to do this is to develop a working fluid-free engine. The consumption of non-working fluid engine is hundreds of times lower than that of working fluid. It should be enough for a few dozen tons of helium-three! It's just that there is no working fluid, and the acceleration is relatively slow. It can take a long time to accelerate to thirty percent of the speed of light. ”

Su Han said: "The last thing I lack now is time!" Anyway, I can't get two million tons of helium. Even if you knock me out to the bone and suck the marrow, it's no fun. You'd better have a reliable approach! ”

Shenlong said: "Then let's focus on the next stage of development on the work-proof engine." ”

……

May.

Su Jinyi held a wedding.

Originally, Su Han wanted to keep a low profile for the first year.

But Su Han's in-laws are within the system.

Therefore, Su Jinyi's marriage was also known to many people in the system.

Many dignitaries and dignitaries came to attend the wedding of Su Han's son.

Su Han naturally didn't want to refuse.

The wedding was also very lively.

……

July.

Bai Peilan accidentally fell and hit her head.

Although he was taken to the hospital afterwards, he was still unconscious.

After the incident, there was a consultation with a specialist.

Diagnosis of intracerebral hemorrhage caused by a fall.

Although the expert operated on Bai Peilan in time, it can be regarded as saving a life. But Bai Peilan is ninety-four years old after all, and she has not been able to wake up after surgery.

Naturally, Shao Yutong was in a hurry.

Su Han didn't have much to do about it.

In fact, whether it is the ninety-six-year-old Zhong Meifang or the ninety-five-year-old Yuan Meixia, they are all old and old.

Yuan Meixia didn't even know Su Han anymore.

I only know the name of the big dragon and the big dragon.

didn't recognize Su Han as his big dragon.

At the moment, Bai Peilan is such a non-lake person, but there is an accident.

Even if you are careful.

Accidents are not completely avoided.

In Su Han's opinion, it seems that the matter of putting his mother into the Shenlong must be advanced.

Although now the mother is still alive.

But danger doesn't happen at any time.

What if I am not at home when the danger occurs?

Even if there is a Shenlong, it is useless.

Think about it, now there is no quality in a mother's life.

Rather than living like the walking dead.

It's better to put it in the Shenlong now.

When there is a chance to wake up in the future, maybe it can hold on for a while.

There was a decision.

Su Han once again mentioned the matter of freezing the three old men to his wives.

Of course, Shao Yutong was a little entangled.

Now this is already the case with Bai Peilan.

It stands to reason that it is also an option to freeze and wait for more advanced medical technology to cure it in the future.

But the problem is that Bai Peilan is already ninety-four years old.

Even if it can be cured in the future, how many days will it live?

Shao Yutong still didn't agree in the end.

Dai Lan's thoughts are the same as Shao Yutong's.

Zhong Meifang is ninety-six.

I won't live for a few years.

There's no need to toss around that much.

The two disagreed.

Su Han didn't say anything.

Anyway, I won't give up Yuan Meixia no matter what.

……

Su Han then asked Shenlong to send some anesthetics from the Shenlong.

He decided to anesthetize Yuan Meixia and send it to the Moon Shenlong for storage.

Just while waiting for the anesthetic.

Su Han returned to his mother.

Su Han waved his hand at the nanny.

The nanny hurriedly withdrew.
