It was late at night, and the original noisy Shenmu City was much quieter.

In a quiet room in the backyard of the 'Yuan Zun' Fu Shop, Liang Feng sat behind a large table, concentrating on writing and drawing on a large sheet of mulberry paper.

Time seemed to stand still, and the only sound in the quiet room was the rustling of the tip of the pen made by Purple Wolf Hao across the mulberry paper.

After a long time, Liang Feng put down his pen, and while sorting out the manuscript paper and putting it into the storage bag, he said to himself: "Thirty-two times the cascading spirit array, it's difficult, it's difficult!"

Before, he had already deeply felt the tremendous value of this layered Spirit Gathering Array, so in the past few years, he had designed and calculated the thirty-two times Spirit Gathering Array whenever he had spare time, but so far, there was still not much progress.

"Alas, the problem now is not just the geometric growth of the amount of calculation, but the deduction in the original way, the most central layer wants to absorb the spirit, gather the spirit, and detain the spirit of thirty-two times the intensity of the aura, not to mention the material problem, the complexity of the magic circle related to the upgrade alone is an exponential increase, and it is impossible to calculate clearly!"

He knew that the more complicated the magic circle, the more difficult it would be to sort out the problems of interference, coupling, and mutual restraint of the related spiritual power lines, let alone solve them, so until now, he still couldn't theoretically upgrade the spirit gathering array that had successfully gathered spirit thirty-two times the intensity of spiritual energy.

Picking up a piece of manuscript paper and shaking it into the storage bag, Liang Feng had a flash of inspiration in his heart, and said secretly: "In my previous life, I had the problem of calculating the landing area of a runaway satellite in low earth orbit, which is quite similar to calculating the spiritual power line of this complicated magic circle......

In the memory of the previous life, before the artificial intelligence 'Tengu-1' system, it was difficult for humans to accurately calculate the landing zone of the runaway satellite-

According to the simplest model, low-orbit unpowered satellites are attracted by the Earth's gravity and fly lower and lower around the Earth, falling on the Earth in a standard spiral. Calculated with this simplest model, of course, the landing zone is very easy to calculate - alas, this is not a fact, but just a model.

A slightly more complicated example is the shooting of a sniper - experienced snipers know that if you want to hit a long-distance target, you must first know the initial velocity of the bullet fired by your sniper rifle, and then you must know the distance from the target, and then you need to know the air temperature, humidity, wind direction, wind speed, altitude and other factors, and then calculate the gravitational force of the earth, air resistance, and other factors when the bullet flies. Wind speed causes deviations, and then, if all these deviations are corrected before shooting, they can accurately hit the target.

However, calculating the landing orbit of an unpowered satellite is extremely complicated, because there are too many factors that affect the orbit of a satellite.

For example, the most influential force is of course the Earth's gravity, but the Earth is not strictly spherical, let alone homogeneous, so when a satellite flies over the Himalayas and when it flies over the Pacific Ocean, there is a slight difference in gravity, and this subtle gravitational pull may eventually significantly change the landing area of the satellite.

If there is only the gravitational force of the earth, the landing area of the satellite can still be accurately calculated, but the shape of the satellite, the initial flight posture, the density of the atmosphere, the gravitational force of the moon, the gravitational force of the sun, the gravitational pull of the sun's major planets, the gravitational pull of the moon to cause the earth's tidal current, the influence of the solar wind, and the influence of sunspots are also affected by the satellite's flight...... And so on and so forth.

So, when all these shifting influences are added together and the effects are stacked, humans have to use the flip of a coin to predict the landing zone.

"The artificial intelligence 'Tengu-1' system solves this problem by making all the impacts into models, then superimposing, and then performing exascale simulation calculations, and then tracking the actual situation and matching it with the simulated ......"

"However, it is due to the incomparably powerful computing power of the 'Tengu 1' system! Although my current computing power is much higher than in my previous life, it is still a drop in the ocean compared to the 'Tengu 1' system!"

"It seems that it is not possible to rely on forced calculations. ...... Well, how did that secret realm with a hundredfold aura come about? Is it also based on calculations?...... Impossible!" Thinking of the secret realm, Liang Feng felt a little figured out - there might be other ways to upgrade this Spirit Gathering Array!

"The time has come, let's practice first!" Liang Feng packed up all his things, and when he was sitting cross-legged on the futon and preparing to practice, suddenly a divine sense swept over-

"Who is so rude?" or ......" Thinking of the very forbearance of the offering, he chuckled in his heart and suddenly became vigilant - as soon as he flipped his hand, he immediately activated a 'Cascading Heavenly Venerable Vajra Talisman', and held a few 'Four Spirit Silver Sword Talismans' in one hand, and a seventh-level Heavenly Thunder Stone in the other.

The 'Five Elements Wind Willow Array' quietly spread out outside the rune shop made a 'ding' sound, and someone entered the backyard of the rune shop!

Sensing the fluctuation of that person's spiritual power, Liang Feng relaxed his heart a little - that person only had the eighth grade of the Dao, and he should not be his opponent.

"He rushed straight into his room with such a violent, obviously the person who came was not good...... Who is he? He's here to kill himself, right? Why?...... Could it be that he is the fourth apprentice who Xu worshipped?...... That's right, spiritual power fluctuations are a bit like that!"

The thought in his heart flashed quickly, and he saw a human-shaped hole appear on the door of the quiet room, and silently, a white-faced scholar shaking a gold and jade bone fan suddenly appeared in the quiet room.

The scholar quickly threw down a few array flags, and then said with a smile: "Yang Shen, you are the Dan Master Yang Shen of the 'Spirit Coriander Flower' Dan Shop who refined the 'Pulp Cleansing Pill'?

Liang Feng was horrified in his heart, the white-faced scholar was Xu Xianfeng's fourth apprentice, but how did he find here? He said, "How did you find here?"

The white-faced scholar waved the gold-painted jade bone fan in his hand, and a red light flashed out, heading straight for Liang Feng's neck, and said, "Go and ask Lord Yama, die!" A look of cruel excitement flashed in his eyes.

In an instant, he felt the lock of the magic weapon before the god arrived, Liang Feng's face changed, and he shouted: "Die!" In an instant, a fist-sized dark green thunderball rushed towards the white light, and four silver glittering spiritual power swords shot towards the white-faced scholar.

"Boom!" The thunderball was the first to collide with the red light, making a dull and muffled sound - the thunderball disappeared, and the red light appeared in its original form and stopped in the air, a blood-red serpentine sword.

'Dang, dang, dang, dang-' The four spiritual power swords struck a piece of dragon pattern armor that appeared in front of the white-faced scholar, making a sonorous sound, and the dragon pattern armor did not move after a few spiritual lights.

Liang Feng's face changed drastically, this person's spiritual power fluctuations were obviously only the eighth grade of the Dao, how could the weapons used to attack and defend were all low-grade magic weapons?! Could it be that he also had some hidden divine skills? In an instant, he immediately made a decision, and summoned in his heart: "Netherworld, help me quickly!"

After advancing to the seventh rank of the Dao, he found that eating the top-grade 'Barrier Breaking Pill' again could slightly nourish the Divine Consciousness Tree in the Sea of Consciousness, so he fed all the one-and-a-half divine consciousness that had been raised by eating the Barrier Breaking Pill to the 'Netherworld Divine Sword'—his current one-and-a-half divine consciousness was about forty percent of that of the Sixth Rank of the Dao.

The white-faced scholar's face became even more powerful than Liang Feng's, and he shouted, "Who are you?"

"Master, I'm coming!" An echo echoed in his head, and a black shadow emerged from the Liangfeng Tianmen acupoint, turning into a black line that seemed to be nothing, and flashed away.

In the air, another dark green thunderball collided with the magic weapon serpentine sword that turned into red light, and the brilliant aura in the quiet room flashed, followed by a dull and abnormal 'boom' sound.

"When, dang, dang, dang—" The four spiritual power silver swords hit the dragon pattern armor, and the dragon pattern armor still did not move.

The white-faced scholar's face relaxed, and he said with a smile: "Haha, donkey skills are exhausted?......

Before the words fell, with a 'bang', a black line passed through the dragon pattern armor, and then through the neck of the white-faced scholar, and then a hovering disappeared in the Liang Fengkou-

The dragon armor let out a terrible cry, and it fell to the ground with two pops. The white-faced scholar's head tilted and slid to the ground, his mouth was still open and closed, but no sound came out, and the headless corpse stood for a moment before falling to the ground, hot blood and steaming.

Liang Feng's heart moved, he quickly stepped forward, took out several forbidden spirit runes and slapped them on the white-faced scholar's head, and then said something in his mouth, pinched the trick with one hand, and pressed it on the round-eyed head with the other-

"Fourth Senior Brother-Fourth Senior Brother——, haven't you done it yet, Master told you to hurry up!" a somewhat shrill voice floated in, and seemed to be in his ears.

Liang Feng's face changed drastically - he sensed that there were two Jindan early stage monks who were moving quickly in this direction!
