It's just that the positions of many planets are different from those currently known.
So Zhang Long manipulated the tools above to bring those planets into their original orbits one by one.
I have to say that this is a little game that requires quite a lot of IQ.
There must be only a handful of people in a kingdom who control the trajectory of the stars.
So it's not surprising to use this thing as a password.
But in this era, most people basically know where each planet should be.
So if Zhang Long arranged them correctly, it would only cost him a little more energy.
After Zhang Long put all the planets into their own orbits.
A rumbling sound was heard, and then the bronze door opened.
"You even understand this?"
"That's for sure. We already learned this knowledge when we were in Huaxia Primary School."
"Shit..."
It is true that cramming literacy education is prevalent in China. No matter what subject it is, it will be very even and everyone must learn it.
But that's not the case in Nicholas's country.
Even when they were learning math, assigning values was not as complicated as 3.1415926.
But four.
After calculation, the value obtained will not deviate too much, and it is completely enough for elementary, middle school and high school students.
And Zhang Long and the others need to know at least 3.1415926535!
I have to say that the primary school students in Nicholas's country are much happier.
There is even time to participate in extracurricular activities such as the Boy Scouts, while Zhang Long and the others can only participate in tutoring classes.
So when facing these problems, Zhang Long naturally has more advantages than Nicholas.
"Well, you don't have to be unhappy. In a team, if there are two people with the same skills, it is a waste.
I can, you can’t, you can, and I can’t either, this is the perfect consequence.”
"Zhang, you are so good at talking, why don't you say more?"
The two of them were chatting and walked into the opened bronze door.
When they walked into the bronze gate, the scene they saw in front of them couldn't help but resemble Nicholas, who uttered foul language again.
"Is this a palace or a maze?"
Because after Nicholas and the others entered, they found that there were five more doors in front of them.
"The question now becomes, which door should we enter?"
"Let's see who can get in first.
Just the two of us, do we still have the qualifications to choose?"
Two people also came to these five doors.
The doors are all about the same size as the bronze door I passed through before.
The so-called difference is that there is a gemstone inlaid in the center of the bronze door.
The colors of gemstones are cyan, red, white, and green.
The gem on another door is missing.
There is only one obvious place, but the color of the gem inside the groove is unknown.
First, Nicholas pushed the green bronze door.
Unexpectedly, this bronze door was undefended and opened easily with a gentle push from Nicholas.
"It's actually so easy this time."
Nicholas and Zhang Long then stood at the door and immediately switched the tactical flashlight to strong light mode, shining a bright light into the dark place inside the door.
But what they saw made Nicholas and Zhang Long a little surprised.
Because what they saw at the door was a place similar to a virgin forest.
It's just that the forest is also quite dark, with no light at all.
All kinds of green plants grow all over the ground, and the weeds on the ground are always as tall as a person.
"Want to go in and have a look?"
"Let's see what's in the other doors first."
Zhang Long thinks what Nicholas said is quite right.
After various comparisons, it would be better to choose one.
So they ignored the green door and went to the bronze door inlaid with rubies next to it.
In this way, even the bronze door was pushed open gently.
But there are steps extending downward inside.
Don't know where it leads.
Use a strong flashlight to shine down.
The light shined very far, and I couldn't see the scene below. It seemed that the stairs were very deep.
Then they came to the white bronze door.
After opening the door, the street is completely opposite to the one next to it.
There are also stairs on one side, but they lead upward.
Then they came to the green door again.
After opening the door, I found that there was a long passage inside.
The walls of the passage are covered with green moss.
The last door was not inlaid with gems, but it could not be pushed open no matter how hard it was pushed.
It seems that the reason why these doors can be opened is because the gems are installed where they should be, so they cannot be opened.
"Zhang, which door should we enter first next?"
"I'm more interested in the unopened doors."
"That's what I always thought."
The two people also looked at each other and smiled, which is also a bad human nature.
"How about using C4 explosives to blow it up and see."
"Forget it, if this palace is blown up again it collapses.
Let’s look at other places first.”
Zhang Long said that he did not go to other doors and walked straight into the door with the green gem.
Nicholas had no choice but to follow the cockroach in. All in all, these doors looked unremarkable.
In comparison, the green door is more difficult to explore. After all, it is filled with various plants. If you want to enter, you have to clear away all the vines and weeds along the way.
It takes a lot of effort, so let’s start with something simple.
Nicholas and Zhang Long walked forward along the open area. The humidity here was very high. Whether it was the ground, the walls, or the top, they were covered with all kinds of moss, which was very slippery.
The two of them didn't dare to take big steps when walking.
And when those black bugs that had been following them came to this door, they all stopped.
"It looks like there should be a water source ahead.
Otherwise, it wouldn’t be so humid.”
Zhang Long had just finished speaking and he had already seen the water source in front of him.
It turns out that the end of this place is a river beach, and below the river beach is a river about ten meters wide.
The overall layout here is similar to the river beach when Zhang Long climbed up from the Ice Pond.
So after Zhang Long saw this situation, he still felt a little bit cordial.
“This place is really too big. Just the two of us exploring it, we really don’t know how long we will have to explore.
But the black bugs that are not here make me feel much better."
Nicholas looked around and said a few words to Zhang Long.
