"The city of Eternal is below..." Lin Chen and the other two quickly arrived at the location of the city of Eternal, pointing to the stretching mountains below, Midarren said.

For countless years, the Eternal City was there, and everyone knows this, but the Eternal City, which has been closed, has never been opened.[..com]

After all, even the Heavenly Punishment of that year was finally able to stand outside, which shows how powerful this Eternal City is. However, it has been closed for nearly 100,000 years, and no one knows the situation inside.

"Eternal City!" Looking at the stretching mountains below, Lin Chen and Qiao Anke were both suspicious gods. Do you know how to talk about the city? Why do you look around and see that they are all just mountain peaks?

Looking at Lin Chen and Joanke's appearance, Mi Daren obviously guessed what they thought. Before they could ask, he took the initiative to explain and said, "Originally, the Eternal City was in this place, but for a hundred thousand years, the whole city has been buried in the mountains due to natural earthquakes. There is only a passage to the cave below, leading to the entrance to the Eternal City."

"Oh, so that's it." Lin Chen nodded suddenly when he heard Mi Daren's words. As he spoke, the three of them landed on the carriage.

As for the eighth-grade unicorn in the Holy Realm? Of course, they stayed obediently in the mountains next to them. This powerful unicorn has almost no wisdom, so they naturally know what to do. Moreover, four eighth-grade unicorns in the Holy Realm are together, I believe there will be no danger.

Following Midarren, Lin Chen and others hurriedly walked towards the entrance of the Eternal City. Although the Eternal City is an ancient existence and everyone knows its location, unfortunately, the person who is truly capable of opening it has never appeared.

Because if you want to open the founder holy land in ancient times, you only need the founder's ability, and you must be a very powerful founder. Even the supreme Deres has been studying for countless years, and he has the ability of the supreme founder, so he found a way to open the Eternal City.

The three rushed towards the Eternal City and soon walked to the bottom of the cave. However, looking at the confined Giant Gate, Midarren frowned tightly. Didn’t Dris say that he had found a way to come to the Eternal City? This gate is still closed? Could it be that he is still preparing somewhere and has not arrived?

"Dris has already entered! But this door should be automatically closed!" Just as Midarren was suspicious, Lin Chen squatted down and then spoke. When he heard Lin Chen's words, Midarren and Joanke looked to the ground.

Sure enough, although the gate, which was corroded by time, was still closed tightly, a clear trace appeared on the ground of the cave. Judging from the traces, it was obviously because the gate was left when it was opened. After seeing this, Dris had indeed entered the Eternal City.

"But, what should I do if the door is closed now?" Although I knew that Dris had entered, the gate of Eternal City was closed. What's the solution?

Although Lin Chen is also a supreme caster, this Eternal City is here, but no one can open it for millions of years. Just Lin Chen? Can it be so easy to open it? Didn’t Dris, who is also a supreme caster, find a way to open the door after years of research?

"It's a bit troublesome to open this door..." After looking at the signs of the opening of the door on the ground, Lin Chen naturally saw the groove on the door again. Looking at the patterns in the groove, Lin Chen frowned.

"Is it just a little trouble? No one can open this gate for nearly 100,000 years. According to legend, several supreme founders have appeared in our divine realm before, but they are all trapped by this gate." When Mi Dalun next to him shook his head and said.

However, as he spoke, he also sighed. The supreme casters in the previous world of the God Realm were stumped by this gate. However, Dris opened it. It can be seen that Dris' casting technique is indeed very powerful, at least surpassing the supreme casters that appeared in the previous world of the God Realm.

Lin Chen didn't say much about Mi Dalun's words, but just looked at the huge door and grooves seriously. Following these textures and magic circles, Lin Chen was secretly deducing the way to open the door.

Although the groove on the door is to open the key hole of the door, it is not just about casting something that just fits in. The shape is not a difficult point. The difficulty is how to use the key to completely start all the magic circles on the door. This is the important thing.

If you want to make a metaphor, you can only say that this gate is like a math problem, and Lin Chen is now starting to answer him.

The problem with this gate is very profound, and it can even be said to be the embodiment of the foundry concept. Even the supreme caster has to scratch his ears and faces in front of this gate, and he can't find a clue.

Staring at the door seriously, Lin Chen was quickly deducing in his mind that it was not difficult to cast a key. The difficulty was how to analyze the answers to casting on this door.

Just in the small keyhole that is the size of a palm, it completely activates the millions of magic arrays of large and small, interlocking in the gate. This almost involves the principle of compression and overlapping of casting magic arrays.

This is like a square. If you draw a line diagonally, the square will become two triangles, but are there lines between both diagonals? Are they exactly four doubled triangles? No, but eight. The compression and overlapping principle of magic arrays is almost the same as this principle, and they are overlapped using some similar places in magic arrays.

Such problems, careful calculations, and the huge number of magic arrays, and the keyhole is only a palm-sized one. The problems one by one have very high requirements for the casting master, and it should even be said to be strict. I believe that even the supreme casting master may not be able to solve them.

Just like high school level Olympiad mathematics, not all high school students can answer it.

However, is Lin Chen's casting ability really only at the supreme level? No! Lin Chen's real casting ability has actually surpassed the supreme level and reached the level of a magic craftsman.
