Bai Wuji looked at Lin Yi in surprise, and a layer of sound insulation vital energy protection suddenly appeared around him.

"This is the secret of our Bai tribe, but I can tell you." Bai Wuji said softly: "The Holy Ancestor has reached the peak of the fifth-level holy realm, and it is just around the corner to ascend. Although he has been deliberately suppressing it, it will be a matter of time before he ascends to the upper realm. Once my Saint Ancestor ascends to the upper realm, our human tribe's situation in the Holy Wu Continent will be even more difficult."

Lin Yi was shocked again.

He thought to himself: "Yes, at this time, there is a saint in the human race who barely restricts the demons from breaking into the Holy Martial Continent for eight thousand miles. Once the White Saint ascends, and once the demons have no restrictions, what will the Holy Martial Continent become?"

Through understanding of the demons during the battle, Lin Yi fully believed that the demon army could definitely sweep the entire Holy Martial Continent.

There is an urgent need for strong people to stand up among the human race!

Stand out and restrain the demons!

Stand out and drive the demons out of the Holy Martial Continent!

Bai Wuji gently patted Lin Yi on the shoulder and said, "Using all means to quickly become stronger, this is not just the business of every human monk himself, but it is already a major event about the life and death of hundreds of millions of people in the Holy Martial Continent!"

Lin Yi pondered for a moment and nodded.

Bai Wuji looked at the green green willows in the mountains, looked at the waterfall that flowed down three thousand feet, and said to Lin Yi earnestly: "Anyone has selfishness, but the reason why a person is great is how he chooses and how he chooses in the face of big things."

"The old beggar is not talented and he is confident that he still has a few strength, so he wants to hold Blue Stone City. The convenient behind Blue Stone City is Amber City. Now most of the human race retreat into Amber City. Once the demon army rushed over, Blue Stone City can also buffer the offensive of the demon army."

"In this way, it can also resist the millions of people in Amber City for a moment and create as much escape time as possible for Amber City." Bai Wuji said with a faint smile.

When Lin Yi heard this, he immediately felt awe.

The inconspicuous city Lord Bai is so chivalrous and kind. Isn’t what he wants to do exactly what he wants to do?

"But, once the demon army rushed over, how long can this Blue Stone City last?" Lin Yi asked.

Bai Wuji said: "If the Blue Stone Array is complete, you can hold on for a year, but what is troublesome now is that for thousands of years, the spy hidden among the human race has secretly destroyed the Blue Stone Array, which makes it extremely difficult to defend the city."

Lin Yi asked curiously: "What is the Blue Stone Array?"

Bai Wuji looked at him deeply and said, "Come with me."

Bai Wuji took Lin Yi and the back mountain of the Lin tribe, heading straight to the city in the center of Blue Stone City.

The city in the city is actually the private residence of the lord.

It has a radius of 1,000 meters, and is equipped with pavilions, towers, rockery, ponds and marshes.

However, Lin Yi keenly realized that whether it was pavilions or rockery, there were either thick dust falling on it, or wild grass and moss growing wildly.

There were not even servants and servants in the huge mansion, and only two guards stood at the gate.

Bai Wuji led Lin Yi through the winding corridor and came to a nine-story stone building.

The stone buildings are built with blue bricks and red tiles, which are very exquisitely built.

Bai Wuji pointed to the six-story stone building and smiled at Lin Yi, "This building is earlier than this mansion, and is called the Tower in the Tower."

Lin Yi nodded slightly.

Walking into the stone building, a thick layer of dust fell on the ground, and cobwebs were covered with corners.

Bai Wuji ignored the spider webs and dust. He led Lin Yi into the first floor hall and came to a black stone pillar where the two of them hugged each other. After he looked around very cautiously, his dirty big hand suddenly slapped the stone pillar.

Suddenly, a sound of a jam came from the ground.

The keen spiritual consciousness told Lin Yi that the sound underground was the sound of the wheel shaft mechanism.

The sound of the jamb bar lasted for five breaths. A crack was slowly cracked on the ground in front of the stone pillar, and the gap became larger and larger.

After a while, the gap turned into a square hole.

There are stone steps in the entrance of the cave, which goes downwards and extends into the darkness.

"Come with me."

Bai Wuji stepped down the stone steps. After a moment of pause, Lin Yi followed him down the stone steps.

Walking down the stone steps, when you reach the end of the stone steps, your eyes suddenly became clear. Lin Yi saw that there was an extremely wide room in front of you.

There are dozens of night pearls embedded on the four walls and top walls of the room, which emit a slightly chilling halo, illuminating the entire room as bright as day.

The four corners of the room are supported by four thick stone pillars. On the open space in the center of the room, there is a huge pattern of array text.

The pattern of the array text is like Bagua, and the Yin and Yang fish in the center of Bagua is lifelike.

Bai Wuji led Lin Yi to the Bagua Formation article and pointed to the Formation article. Bai Wuji said, "Did you see it? This Formation article is the aerial view of the entire Blue Stone City. Once the two keys in my hand are inserted into the Formation article, the entire Blue Stone Array will be activated."

After saying that, two polygonal sapphires appeared in Bai Wuji's palm. The two sapphires were the size of eggs, crystal clear, and they were very valuable at first glance.

In front of Lin Yi, Bai Wuji embedded two sapphires into the eyes of the two Yin and Yang fish in the Bagua diagram.

Suddenly, the Yin-Yang Fish became smaller and smaller, and in an instant, it became as small as an adult little finger.

At the same time, the entire gossip pattern began to flash fluorescently.

Under the fluorescent light, a lifelike bird's-eye view of Blue Stone City is presented in front of Lin Yi.

The moat around the city outside the Blue Stone City, the moat together with the river channel entering the city, the weeping willows beside the river channel, and the rotten wooden boats beside the weeping willows...

The entire Blue Stone City was presented to Lin Yi in the blink of an eye.

Suddenly, there was a slight movement underground.

Bai Wuji said to Lin Yi: "When the Blue Stone Array is opened, it will communicate the spiritual energy of heaven and earth and instill it into the formation. There will be slight abnormal movements on the ground. This is a normal phenomenon, don't be afraid."

Lin Yi nodded, and he looked at the topographic map of Blue Stone City in front of him in surprise, speechless for a long time.

He himself is an extremely wise formation master, so he naturally saw through the structural principles of the entire Blue Stone Array at a glance.

The Blue Stone Array relies on all the rivers in the entire Blue Stone City to integrate all the rivers, and then communicate the spiritual energy of heaven and earth, using these spiritual energy as the driving force for the operation of the Blue Stone Array. This is definitely the work of an extremely clever formation master.

The manpower and material resources required to make such a huge array are simply unimaginable.

However, Lin Yi could imagine that once the Blue Stone Array is opened, it will be a very terrifying defensive array, and this array is simply perfect.

Bai Wuji said that once the Blue Stone Formation is opened, there will be no problem to stick to Blue Stone City for a year. This is still a conservative statement. As long as the big formation is not broken, you can stick to it for ten or eight years, or even longer.

However, looking at the lines on the formation, Lin Yi frowned.
