Chapter 436 Nine-Square Grid

Buzz buzz buzz!

Ye Yunfan appeared outside Tianjian City, which made him a little confused.

"Wasn't I in the Sword Pavilion just now? I also got a sword intention. How come it came out now?" He was a little confused for a moment.

"Lingbao, help me see what's different here!" Ye Yunfan called Lingbao and asked her again hoping to get an answer.

"Daddy, there is an entrance here. I'll take you in." Lingbao saw the entrance on the wall on the left side of the city gate at a glance.

When Ye Yunfan entered, he also saw a huge space with no end in sight.

"This should be the underground space of Tianjian City. Is it every sword city?"

Ye Yunfan already had a guess in his heart, and he felt that it was almost certain.

This time was different from before. As soon as he entered, he was directly teleported to the middle position. The surrounding area was as thick as a hundred feet or even hundreds of feet of boulders, but there was a switch next to the boulders.

"Huh? There are also patterns? What is this?" Ye Yunfan kept shuttling in the Nine Palaces. After a few hours, he roughly understood the situation here.

This is a nine-square grid with eight patterns. He needs to piece together all the patterns, and then he will comprehend and fill in the remaining piece.

The pattern here looks ordinary, but it is actually very complicated. With Ye Yunfan's mental power, he has simulated one in his mind. This pattern is a giant sword.

But he still needs to figure out the direction of the nine-square grid. How to accurately reach the position he wants to go to requires constantly moving the boulders.

Ye Yunfan did not study this kind of knowledge when he was in the fairy world. He did not expect that there are various mysteries in the formation. He was fortunate to have various cultivation experiences left to him by the mysterious person, otherwise he really didn't know what to do.

Two hours later, he had basically mastered the mysteries of the nine-square grid.

He also started to move. First, he turned left from the first square grid to the second square grid, pressed the switch and turned right.

Then he came to the third square grid, pressed the switch to turn left, and then came to the fourth square grid, pressed the switch to turn right.

Only Ye Yunfan was seen moving back and forth on the nine-square grid at a high speed, constantly moving the boulders.

But the boulder was pushed very slowly. It took more than ten breaths to move the boulder each time the switch was pressed.

It took five hours for him to finally piece together the pattern of the giant sword, leaving only the position where Gong Jiu stood. There was a gap here, without a pattern, but Ye Yunfan needed to comprehend it himself and use his mental power to condense it.

He was not panicked at all. He concentrated his mind and imagined himself as a sword and a boulder pattern, immersing all his thoughts in his sword intent.

There was a ball of purple and white light in his body. The two-color light balls merged into one and began to expand continuously.

From the size of a finger, it continued to condense and reached the size of a fist.

It was still expanding. After an hour, it was five times the size of the fist just now.

Boom!

With a loud bang, a ball of purple and white light burst out of the body, and a sword intent with the power of thunder and lightning rushed straight into Jiugong.

The light ball continuously condensed a pattern of the hilt of a giant sword at the position of Gong Jiu, and it was formed after a moment, and then began to echo with the overall pattern of the boulder.

Buzz buzz buzz!

Jiugong trembled, and the pattern on the boulder began to merge. The purple-white hilt and the giant sword completely merged into one, and there were traces of lightning on the hilt.

Swish!

This fused giant sword pattern was incredibly peeled off from the boulder and floated into the air.

Then it rushed into the body of Ye Yunfan who was sitting cross-legged on the spot at a very fast speed.

Boom!

Ye Yunfan's body made a muffled sound and his body trembled.

At this moment, his sword intent realm was improved again, reaching the late stage of the heart sword without trace.

And at the same moment, his cultivation level was also improved, reaching the second level of the God Wheel Realm.

The giant sword pattern just now was also a sword intent. After being poured into Ye Yunfan's body, his sword intent realm and cultivation level were improved at the same time.

At this moment, Ye Yunfan smiled. He was very satisfied with what he had gained this time, and then he took a step out.

Buzz buzz buzz!

Just as he imagined, he came to the outside of the Sword Forging City this time.

"It seems that my guess is right. The four sword cities in the Hengjian Domain are indeed the other half of the Sword Pavilion. On the surface, they are sword cities, but in fact, they are actually underground sword pavilions."

He smiled. The information provided by Baili Wentian this time helped him a lot. The Sword Pavilion is really a good thing.

The same Lingbao took him into the sealed door of the Sword Forging City.

The space inside is not as boundless as the previous two times he entered, but there is a huge furnace tripod.

This furnace tripod is a thousand feet long and a hundred feet high. It is not an ordinary thing at first glance. There are green patterns on the body of the tripod and various array inscriptions on the corners of the tripod.

Ye Yunfan determined at a glance that this furnace tripod has reached the level of an immortal weapon. This kind of furnace tripod used to refine magic weapons will definitely achieve twice the result with half the effort.

As soon as he walked in front of the tripod, a line of words condensed in the space. Those who want to pass this level and obtain this tripod need to refine a fairy sword.

A batch of refining materials appeared in front of the tripod, suspended in the air.

"Refine a weapon? And you have to refine a fairy sword? Interesting!"

If it were someone else, it would definitely be a panic, but Ye Yunfan had already refined many fairy swords before, so it was not difficult for him.

As long as there are enough materials, with his current mental strength, he can complete this task.

"What kind of immortal weapon should I refine?" Ye Yunfan looked at the materials suspended in the air and began to ponder.

"Wow, there are so many good things. Ten thousand year black iron? Thousand year copper essence? Thunder unicorn iron? Ruyi magic stone? Golden thunder bamboo?"

When Ye Yunfan saw these materials, he had an idea in his mind. He wanted to refine a thunder attribute immortal sword.

Now that he is powerful, if he uses the immortal sword, the power will be greater. Although it will consume more, it is very useful when it comes to saving lives.

After making up his mind, Ye Yunfan immediately started to act.

"Xiaoqing, go and increase the temperature of the immortal cauldron for me."

Ye Yunfan called out and asked the Qinglian Earth Core Fire to work.

"Immortal cauldron?" Originally, the Qinglian Earth Core Fire was a little reluctant. It consumed a lot before. Although Ye Yunfan had improved his cultivation by one level, he had not fully recovered.

But when it heard the immortal cauldron, it immediately moved.

The immortal cauldron was extremely thick. Even the Qinglian Earth Core Fire took three hours to heat the cauldron.

Ye Yunfan stood on the cauldron, first threw the ten thousand year black iron into it, and began to use the fire to burn it continuously.

The temperature inside the cauldron rose rapidly. At this moment, Ye Yunfan began to control the fire. The temperature should not be too high, otherwise other materials might be melted instantly.

After the ten thousand year black iron was burned for two hours, Ye Yunfan placed the Ruyi God Stone and Leilin Iron into the furnace. It can be imagined how difficult the ten thousand year black iron is to melt, and the melting point is extremely high.

Ye Yunfan used his mental power to accurately control the three items, placing them in three positions of the furnace and burning them separately.

Time passed slowly...
