In Gouzhu's eyes, this pure Yang formation wall is not invisible, but a dense network woven with neatly arranged light red spiritual machine threads. All the spiritual machine lines are woven from the array on the tower.

It is drawn out from the pattern, and finally included in the pattern on the tower.

In addition to the formation patterns on the Thorny Sky Tower, there are four formations on each floor holding a formation pivot and sitting on one side, which can affect some of the spiritual lines at any time. However, at this time, except for the formations on the top floor, the formations on the top floor unfolded the Pure Yang Formation Wall.

Except for this, everyone else's queues are idle.

When Gou Zhu saw this situation for the first time, he thought something had gone wrong with Ji Yan, an old lunatic, and he wanted to commit suicide.

After being blocked, countless red-haired baboons frantically attacked the pure sun formation wall with their claws. These hard spiritual lines were connected to the formation patterns on the tower, and every attack caused sparks to fly from these formations.

After the red-haired baboons in the front were blocked, the ones behind them continued to climb up the pile of similar ones, and soon it was piled up like a wall of baboons. They continued to violently attack the pure sun array wall, and the entire tower kept shaking.

These baboons have extremely sharp claws, which violently tear into the walls of the Pure Sun Formation, constantly tearing out gaps one after another.

Although the Pure Yang Formation Wall can be continuously repaired by absorbing the Pure Yang Spiritual Energy of Heaven and Earth from the Thorny Sky Tower, the degree of repair is always limited. Under such a fierce attack, if more demon baboons surge from behind, the wall will be extremely damaged.

You may not be able to bear it.

Gouzhu thought to himself, is this old man Ji Yan crazy? The Citian Tower can obviously deploy many layers of defensive walls, but he only opened one layer? At this moment, he almost turned around and went straight to the underground of the Citian Tower towards the city.

The passage escaped.

At this time, Ji Yan, who was sitting at the top of the tower, ordered without changing his expression: "Open the eighth floor!"

After receiving the order, the four formations sitting on the eighth floor immediately injected their spiritual thoughts into the center of the formation. At the same time, the countless mysterious lines drawn on the wall of the eighth floor began to shake like sparkling waves.

Shining with colorful brilliance.

Light red vertical and horizontal spiritual threads shot out from the tower, and countless invisible hands seemed to be threading needles and threads, weaving into an airtight network in an instant.

This newly formed pure sun formation wall is larger than the original first floor, which also isolates the vanguard of the demon baboons who rush to the front and violently attack the innermost formation wall from the reinforcements behind.

Come on. In this way, the attack intensity received by the innermost layer has finally stabilized and will no longer increase.

At the same time, the baboons began to stack up like stacks of arhats at the new layer of the formation wall, and began to attack this new layer of formation wall.

In this way, one layer, two layers, and three layers, circles of protection, were continuously unfolded from the inside out. After half an hour, a total of nine layers were unfolded.

The nine layers of protection also sealed a large number of red-haired baboons, probably as many as a thousand in total. Fortunately, the targets attacked by so many baboons were scattered on nine different layers of walls.

The formations and stones all over the tower were being violently impacted, and the spiritual light was shaking erratically. However, because the force was evenly distributed, this kind of attack could still be withstood for a period of time.

At the same time, although Gouzhu could not see the inside of the tower, he could clearly feel that some powerful spiritual power was accumulating in the tower, like a huge bowstring being gradually tightened.

This kind of power accumulation has been going on continuously since the end of the last wave, but it has not yet reached perfection. The process of power accumulation is not related to the deployment of nine layers of protection. But Ji Yan is sitting alone in the main seat of the formation.

Take control of everything with ease.

He must ensure that the time for all nine layers of defense to be deployed is almost the same as the time for the Thorny Sky Tower to be fully charged, and that no layer of the pure sun formation wall will be breached by the demon baboon.

Viewed from the outside, the entire Citian Tower is surrounded by nine circles of red-haired baboons. It is spectacular, like a huge Beijing view. All the patterns on the tower wall have been brightened to the limit, and the tower wall has become

It was scalding hot, as if it might burst into flames at any moment.

At this moment, a "clunking" sound seemed to be heard from inside the tower. An extremely load-bearing object in the tower seemed to have been suspended to the highest point and embedded in a groove somewhere.

The mechanisms in this tower are completely closed, and Gou Zhu has never seen its internal structure. But the leader of the array, Ji Yan, is sitting on the top of the tower and controlling everything. The bowstring has been tightened, and the defensive array of the Spiking Sky Tower cannot withstand it.

He had reached his limit. Without hesitation, he injected a ray of spiritual thought into the core of the formation.

Suddenly there was a clicking sound deep in the heart of the tower, followed by a series of muffled sounds of friction. Every guard on the tower could feel that something extremely heavy fell from a height in the center of the tower, hitting the ground.

On the base of the tower, there was a heavy and muffled "boom" sound.

At the same time as this muffled sound, Gouzhu felt that the air around his body was squeezing and twisting. At this moment, not only could he not breathe, but his heartbeat seemed to have been squeezed to a halt.

A strange shock wave appeared directly in the surrounding area. As far as Gouzhu's naked eyes could see, the ground around the Tower of Thorns had a circle of obvious ripples like water.

The power of waves ripples out from this circle of ripples, but it is not obvious when it reaches the tower. This is because the power comes from all directions and when it reaches the Thorny Sky Tower in the middle, they cancel each other out, leaving not much power left.

OK. Gouzhu means feeling the air tightening, the blood in the body surging, and the heart in the chest beating twice.

But the surroundings were different. Waves spread out in circles like ripples, and wherever they went, the ground shook together with the countless baboons above.

The solid pure sun array wall can block all foreign objects, but it has no defense against this kind of shock. Not only that, the nine-circle pure-yang array wall also vibrates together, concentrating its power into the terrifying like a nine-circle trumpet.

situation.

This kind of vibration does not have much impact on the land and dense forests. However, it has great power on the blood and organs in animals. Violent vibrations can directly explode the heart and blood vessels, and shake the brain into mud.

In the blink of an eye, all the red-haired baboons within a mile of the Citian Tower died, rolling down like a pile of fruit and piling up on the ground.

This shock wave continued to spread outward, and the circle expanded to tens of miles away. However, the farther the distance, the smaller the power. The baboons affected outside the array wall did not die, but were temporarily fainted. Soon after

You will wake up and gradually regain your strength.

At this moment, there was a creaking sound from the nearby city wall. Behind the tall bamboo fences, several wide bamboo plank bridges were lowered. The Cangmao people who had been prepared in the city rushed out with wooden carts.

Filled with red baboon carcasses and transported back to the city.

They have half an hour to move. After half an hour, the beast tide will come again, the city gate will be closed, and the blood refiners who are too late to enter the city will be mercilessly locked outside the city and become food for baboons. This time

The Inner Thorn Tower will also start to accumulate power again, until the siege of the beast tide reaches its peak, and the defense of the Thorn Tower reaches its limit.

After a busy day, when the afterglow of the setting sun shone on the deep gorge of the city protection, Muge, the leader of the Cangtuo tribe, made his last inspection around the Citian Tower. He heard a long horn sound, and decisively ordered everyone to

The still busy Cangmao people abandoned the wooden carts in their hands and ran into the city.

The suspension bridge was retracted, and the beast tide surged in, but most of them rushed in the direction of the Thorny Sky Tower. There were not many baboons who actually tried to jump over the canyon to attack the fence. Most of them rushed to the edge of the canyon to watch for a while, except for a few

The head couldn't stop the car and fell into the deep ravine. The others bared their teeth and howled at the other side before leaving in the direction of Citian Pagoda.

On the side of the city where the suspension bridge has been retracted, the Cangmao people are racing against time to skin and remove the bones of the mountain of red-haired baboon carcasses, remove the dirty internal organs, put the clean flesh and blood in wooden barrels, and continue to carry them manually.

The ground was poured into three large bronze cauldrons.

This step must be done quickly. After the death of a monster, the body is constantly bleeding. The fresher the flesh and blood, the purer the refined blood spirit stone will be. Those filthy internal organs cannot be refined to bleed.

If the bones of the spirit stone are mixed into it, the whole pot of blood spirit stone will be mixed with impurities, the quality will be greatly reduced, and the whole pot may even be scrapped.

Others are constantly grinding some mineral and plant raw materials into powder and accurately proportioning them into so-called "auxiliary materials." These auxiliary materials must be prepared on site and used immediately, otherwise their medicinal effects will continue to be lost. Each blood refining

Each tribe controls a unique formula of excipients, and the refined blood spirit stones have different advantages and disadvantages, and each has its own characteristics.

They had already built a high platform and lifting pulleys next to the three big cauldrons. The pulleys were rotating constantly, constantly transporting buckets of flesh and blood to the high platform and dumping them into the bronze cauldrons. A refiner directed the young man to accurately

Add various auxiliary ingredients step by step. A strange fragrance wafts from the cauldron.

After brewing for about an hour, under the command of the refiner, everyone pulled the pulleys and levers to carefully tilt the giant cauldron.

A liquid with a peculiar fragrance, exuding red light and translucent, as red as agate, and as viscous as honey was poured out and poured into the many square molds that had been prepared below.

After another quarter of an hour, the heat dissipated. If Gou was killed here, he would have to stare out his eyes. I saw them tipping the mold, and there was a burst of clattering sounds of pearls, and pieces the size of dominoes were transparent and crystal red.
