Using Source Stones to inscribe runes was, in a way, the same as using banknotes to cut window decorations on Cerule when it was still called Earth. It was a luxury. However, in Gu Ding's current Inventory, he had the most Source Stones and a limited amount of other materials.

A Source Stone was only the size of a thumb. It would be very difficult for an ordinary person to inscribe runes on it. However, for deities like Gu Ding, size was not a problem. With Gu Ding's current strength, he could easily inscribe on nano-scale bacteria, let alone a Source Stone the size of a thumb.

However, the difficulty of inscribing runes was that if one did not master the corresponding runes, the inscribed lines would automatically deform. It felt as if someone had suddenly slapped the hand that was holding the brush while he was drawing, destroying the painstakingly drawn painting.

Gu Ding spent three days on the first rune, spent more than a thousand Source Stones, and failed nearly seven thousand times. Unable to bear it, Gu Ding finally swallowed a Universe Fruit and entered Epiphany again.

Gu Ding entered Epiphany for the second time, which surprised Neptune. There was a chance of entering Epiphany after consuming a Universe Fruit, and the chance was usually not high. However, Gu Ding took it twice in a row and entered Epiphany both times.

In Epiphany, Gu Ding's understanding of the runes finally deepened.

He only tried 55 times before he succeeded in inscribing the first dao pattern.

In the past, Gu Ding would have been ecstatic. However, in Epiphany, Gu Ding maintained absolute rationality. He did not hesitate and began to inscribe the second rune.

The second rune was successfully inscribed fifty-four times.

Then, the third rune was successfully inscribed fifty-three times.

The fourth rune was successfully inscribed fifty-three times …

The subsequent runes were successfully inscribed about fifty times.

Gu Ding used less than ninety days to inscribe all three thousand and six hundred offensive runes.

Runes were extremely mysterious. Once they were successfully inscribed, it was equivalent to being recognized by the rune. It would not be a problem to inscribe more runes in the future.

According to Neptune, without Epiphany, with Gu Ding's demonic aptitude, it would be good if he could comprehend one rune in a year. Even if it was Mi Ke Ke, an existence with a heaven-defying brain, it would probably be difficult for her to comprehend a dao pattern without two or three months.

However, in the state of epiphany, Gu Ding was able to comprehend forty Dao patterns in a day. This was the benefit of epiphany.

After the 3,600 offensive dao patterns were carved, the effect of the epiphany was gradually fading.

Due to the fact that sudden enlightenment was extremely taxing on one's brain power, one had to wait at least three days before consuming the Universe Fruit.

Gu Ding spent a few more days practicing the runes he had learned.

Three days later, Gu Ding took another Universe Fruit and successfully entered the state of epiphany. This made Neptune feel a little incredulous, but the facts were right in front of him. Neptune could only attribute this high probability of entering the state of epiphany to Gu Ding's special physique.

It took Gu Ding ninety-two days to master all three thousand six hundred defensive runes.

If not for the 500 times time acceleration effect of the Cultivation Tower, half a year would have already passed.

After practicing the defensive dao pattern for a few days, Gu Ding took the Universe Fruit for the third time and quickly entered a state of epiphany.

It took Gu Ding a little longer to master the three thousand and six hundred other types of Dao Markings. It took him more than a hundred and twenty days to master them all.

At this point, more than three hundred days had passed, and Gu Ding had mastered all ten thousand and eight hundred Taoist patterns that Neptune had inscribed in his mind.

"Now that you have grasped the basic dao patterns, you can start to learn the arrangement and composition of the dao patterns." The Sea Sovereign's voice had a mischievous smile.

Only then did Gu Ding realize that he seemed to have accidentally jumped into a deep pit. It took him nearly a year to learn more than ten thousand basic Dao patterns, and in the end, he was told that there were more combinations after that.

"Actually, it's not that complicated. If it was someone else, they would definitely have to calculate the effects of various combinations. However, I've already calculated all of these things. You just need to follow the combination I gave you and burn it. If Mi Ke Ke were to learn this, I would definitely let him calculate it himself, because this is also something that trains the brain. "Neptune laughed.

Gu Ding was a little relieved. If he really had to calculate it himself, he would probably collapse. Fortunately, he only had to directly inscribe the combinations that Neptune had already calculated.

"Let's start with the simplest double combination. If you want to combine it at will, there are hundreds of millions of double combinations of Taoist patterns. However, I've simulated these hundreds of millions of combinations, and there are not many effective ones, only one hundred and twenty thousand. Inscribe these one hundred and twenty thousand combinations three times and familiarize yourself with them. Then, I'll teach you the triple combination. "

After listening to Neptune's words, the corner of Gu Ding's mouth twitched slightly. "One hundred and twenty thousand …"

However, Gu Ding quickly got into the zone. He swallowed another Universe Fruit and spent a hundred and eighty days to inscribe the double combination three times and reach complete mastery.

"The triple combination is a little less effective. There are only a little more than a hundred thousand. Continue familiarizing yourself with it."

After eating the Universe Fruit, Gu Ding spent more than a hundred and fifty days to completely master the triple combination.

Then, Gu Ding spent about five hundred days to complete the quadruple combination, then the quintuple combination, then the sixfold combination. Gu Ding spent all of the Universe Fruits in his possession.

"Basic Taoist patterns can have a maximum of nine combinations. From one to five, the refined tools correspond to 1-Star to 5-Star God Items. With six combinations, you can already refine pseudo-spiritual items. This is also the limit of your current soul strength. That's enough to melt the stars. " Neptune did not let Gu Ding continue to try the seven-combination combination. One reason was that Gu Ding's soul strength was not strong enough, and the other was that Gu Ding no longer had any Universe Fruits to carry out the epiphany.

"But, the materials to melt the stars …" Gu Ding was a little troubled. He had almost no craftsmanship materials on hand. Other than some useful things, the spoils of war he had obtained in the past had basically been sold at the previous auction. This included some pseudo-spiritual items, spiritual items, and craftsmanship materials that he had no use for.

"It's okay. Let's refine two Star Embryos first and slowly add the materials later." Neptune had already planned it out. "As for the main materials, we'll use the two half-step true god-level platinum skeletons."

The two skeletons that Neptune mentioned were the two platinum skeletons that Gu Ding had previously obtained from the ancient ruins. Gu Ding had originally planned to keep them until his Sacred Fire was strong enough to absorb the blood and vitality within them.

"I can't refine those two platinum skeletons at my current level. Even if I can refine them, it would be a pity to waste the large amount of vitality energy contained in them …"

"That vitality energy won't actually improve your combat effectiveness much. Moreover, resources to replenish vitality energy can be bought with money. However, materials suitable for refining stars are extremely rare. As for what you said about not being able to refine them, you've completely forgotten the function of the spirit vein hot spring. As long as it's not a true god-level spirit item, the spirit vein hot spring can melt it into liquid form. "Neptune gave a different opinion, and every word he said hit the nail on the head.

"Alright then." Gu Ding could not refute it and could only nod helplessly.

After taking out the spirit vein hot spring, Gu Ding threw the two platinum skeletons into it one after another. Within a few days, the hot spring had melted two pools of platinum liquid.

Under Neptune's guidance, Gu Ding used the Five-Colored Sacred Fire to nourish the two pools of liquid. He also engraved eight sixth-level offensive dao patterns, six sixth-level defensive dao patterns, three toughness dao patterns, three gravity dao patterns, two toughness dao patterns, two repair dao patterns, one miniaturization dao pattern, and one transformation dao pattern.

After the dao patterns were imprinted, the inside of the metal spheres kept tumbling like boiling water. After a few days, the metal spheres seemed to shrink, getting smaller by the day.

The two huge metal spheres that were originally more than three meters in diameter had shrunk to the size of a thumb in less than ten days.

What Gu Ding did not know was that while he was in the Cultivation Tower, more than two days had passed in the outside world.

The arena had originally told Gu Ding that he would rest for a day, but Gu Ding had not been seen for two days. This caused many people who were looking forward to watching Gu Ding's match to rush over the next day to find that they had been stood up.

At the Cultivation Tower, news finally spread that Gu Ding had entered the ninth floor and had been cultivating for two days.

On the Warden's side, the rules for winning more than a thousand battles had also come out.

Above a thousand battles, there was no longer a doubling of a hundred consecutive wins, but a doubling of a thousand consecutive wins. In other words, the points that could be doubled by winning 1,100 battles had to be doubled by winning 2,000 battles.

Not only that, but there was also an interception competition for every thousand battles. The challenger of the interception competition was a reserve member of the Purgatory Gate's keeper. Only by winning the interception competition could one get doubled points.

These two new rules also caused the prisoners who were locked up to hiss.

Gu Ding was unaware of what was happening outside. He had put all his energy into cultivating his Dao Runes and refining stars.

"That's it?" Gu Ding could feel the terrifying aura of these two stars.

"It's done. Although it's just a rough shape, it's very successful. I'm afraid none of the pseudo-spiritual items in the Cosmic Sea can match the attack power of your stars. " The dao patterns that Neptune had given Gu Ding were all carefully calculated, and he had added a total of twenty-six sixth-grade dao patterns. In the Human Camp's Cosmic Sea, those who could add more than ten sixth-grade dao patterns to pseudo-spiritual items were already considered Master Craftsmen. Of course, this was also thanks to the fact that the two platinum skeletons themselves were very high-quality craftsmen materials.

Holding the two silver beads that were as heavy as mountains in his hand, Gu Ding felt a little happy as he looked at them carefully. This was his first time crafting weapons. Although he had refined two rough shapes of stars, it was still a great sense of accomplishment. He immediately dripped a drop of blood on them to make the two stars recognize him as their master, and then he kept them in his Micro World.

Once he was done, Gu Ding stepped out of the cultivation room …
