After becoming familiar with the skill application of Bone Break, Nie Yan began to frantically practice the skill's proficiency.

Completion rate 93%, completion rate 95%, completion rate 96%...

After casting Bone Break more times, Nie Yan became more and more familiar with the skill, gradually mastering more tricks, constantly adjusting his movements in practice, and reaching a maximum completion rate of about 98%. In the eyes of ordinary players, this was an incredible thing. 100% completion was almost impossible, and 98% was also an unbelievable value.

As Nie Yan cast Bone Break more and more times, the skill proficiency skyrocketed. Before long, another crisp system prompt sounded, and Bone Break reached level five.

In the entire Greenland Empire, Nie Yan was probably the only one who could raise a free skill to level five. Free skills were notoriously difficult to train. It was already pretty good to train ordinary skills to level five, let alone free skills!

If he were to hit a player from behind with a level-five Bone Break with 90% completion, even a warrior would lose half of his life if he didn't die. Plus, Bone Break had a stun effect, so the target would definitely die during that period of control.

Nie Yan diligently practiced his skills, spending an entire day, and Bone Break's level skyrocketed to level eight. A terrifying level-eight Bone Break could deal 600% damage at 90% completion!

The intensity of this damage left Nie Yan speechless. So, free skills could be this strong! He had never realized it in his previous life. This was why he was only a second-rate player in his past life.

Nie Yan went into stealth behind a Minotaur Warrior and used Bone Break on the Minotaur Warrior's back. A damage value of 7,500 floated above the Minotaur Warrior's head, and he was stunned for seven seconds.

After a round of skill casting, he used Bone Break again.

After about seventy seconds, the Minotaur Warrior staggered and fell to the ground. With Nie Yan's high damage, the Minotaur Warrior couldn't withstand it, no matter how fast his health recovery was.

It used to take a full two minutes to kill a Minotaur Warrior, but now it only took seventy seconds. The increase in combat power made Nie Yan feel excited.

Killing the Minotaur Warrior yielded good results. The Minotaur Warrior didn't drop anything else, only skill books. There were many rare skills, and there were three free skill books alone, but they were for warriors and paladins.

Since he had already reached level eight, Nie Yan still wanted to aim higher, but the higher he went, the more skill proficiency he needed. According to the skill proficiency required for leveling up, it would take at least three days to reach level nine.

While training Bone Break, Nie Yan also explored other skills, including Backstab, Phantom Assassination, Counter, and Instant Strike. With the precedent of Bone Break, he quickly found some clues when exploring other skills.

Backstab, Counter, and Bone Break were similar in that they all concentrated power on the arm through body movements and then unleashed it. Phantom Assassination and Instant Strike, on the other hand, used a brief burst of acceleration to penetrate the opponent, achieving high damage.

After spending another day, Nie Yan familiarized himself with skills like Backstab. Although he couldn't be as proficient as with Bone Break, he had made some progress.

Soon, Backstab, Counter, Phantom Assassination, and Instant Strike successively reached level five. After reaching level five, these skills were already very powerful. They were invincible when farming monsters, and he could take down a Minotaur Warrior in fifty seconds.

Although his level didn't go up, Nie Yan could clearly feel that his strength was rapidly skyrocketing after becoming familiar with these skills.

Brilliant Cutlass and the others could laugh at all warriors with level-five and level-six Minotaur Strength and War God's Fury, but at this moment, Nie Yan had five or more free skills above level five. It was estimated that Brilliant Cutlass, Watery Reflection, and the others would have a hard time lasting a minute in Nie Yan's hands.

After training skills for another day, Nie Yan looked at Bone Break's proficiency, which had reached 36% of level eight, which was not bad.

Just as Nie Yan was frantically practicing skill proficiency, the war between the Niu Ren Tribe and the Mage Alliance was in full swing, and the Niu Ren Tribe once again showed people how terrifying they were.

The Mage Alliance's 200,000-strong army, with six ironclad catapults, attempted to intercept the Niu Ren Tribe to prevent them from spreading the war to Aijietun Fortress. With 200,000 against 60,000, they suffered a painful defeat, losing more than 60,000 people, all six catapults were destroyed, and they fled in embarrassment. The Niu Ren Tribe, on the other hand, lost only over 2,000 people.

The walls of Aijietun Fortress had been built by the Mage Alliance as solid as iron barrels. They had to wait for the Niu Ren Tribe's ballistic catapults to be built before they could start attacking the city. Therefore, Brilliant Cutlass and the others were not in a hurry to attack Aijietun Fortress. They would fight a war of attrition with the Mage Alliance and consume some of their strength first.

The construction of ballistic catapults was proceeding in an orderly manner. Nie Yan had three slaves, including the little female slave Delphinia, who had the talent to copy blueprints. In nearly a week, she copied two copies of the ballistic catapult blueprints. Three teams of mechanics produced ballistic catapults together, and the speed immediately increased a lot. It was believed that a large number of ballistic catapults would be produced soon.

The number of Niu Ren Tribe's Frost Ironclad Catapults was constantly increasing. One after another, the Frost Ironclad Catapults that had been produced were put into use, and the number of Frost Ironclad Catapults had increased to twenty-five, and the number was still climbing.

With so many Frost Ironclad Catapults, they were simply unmatched. The Niu Ren Tribe rampaged in Moonlight City, and the Mage Alliance didn't dare to fart, and could only huddle in Aijietun Fortress and constantly build walls. They didn't know where they got some giant crossbows, equipped them on the towers, and moved some ironclad catapults to the top of the city walls. In this way, the city defense was very strong.

Kuang Fa had unspeakable suffering. The Niu Ren Tribe, these damned people, had already bombarded six fortresses of the Mage Alliance. The six fortresses that he had built at a great price had been reduced to ruins. If the Niu Ren Tribe had only occupied the Mage Alliance's fortresses, that would have been fine, and they could have fought back, but the Niu Ren Tribe didn't give them any chance at all, and directly flattened the fortresses. Even if they fought back the fortresses in the future, they would have to start from scratch, bit by bit.

After the Niu Ren Tribe's catapults bombarded the sixth fortress, they rushed to the next fortress. The Mage Alliance was a big tycoon in Moonlight City, and there were more than twenty fortresses alone. They had only demolished six so far. Counting the five fortresses won in the previous bet, the Niu Ren Tribe had only knocked down less than half.

If this continued, in a few days, the Mage Alliance would only have the lonely Aijietun Fortress left. It was estimated that Kuang Fa would have a hard time holding back. Once the Mage Alliance's troops left Aijietun Fortress, the tortoise shell, they would become the target of the Frost Ironclad Catapults again.

Players in the Greenland Empire and the Saturn Empire were discussing the war between the Niu Ren Tribe and the Mage Alliance. In the current situation, the Niu Ren Tribe was pressing the Mage Alliance to fight with less than half of their troops, which surprised them. If there were no reinforcements, the Mage Alliance would probably not be able to hold on. Even if the Niu Ren Tribe failed to take Aijietun Fortress, all the other fortresses would be destroyed, and the Mage Alliance would probably not be able to get up for several months.

The war was still going on.

Gryphon Woodlands, this place was full of vast white mist, and from time to time some large bird-like creatures flew by, making it full of danger.

This was the place to obtain flying mounts. A team of about several thousand players passed through the vast white mist and traveled through the jungle.

"Boss, the last time we came, it should be near here. Do we want to use the Mist Dispelling Scroll?" a mage player asked.

The leader of this team of players was none other than Angel Corps' boss, Ang Yi Tian Shi.

"Have our people found out how the Mist Dispelling Scroll came about?" Ang Yi Tian Shi asked. They had used a Mist Dispelling Scroll before and found that with the Mist Dispelling Scroll, their exploration of Gryphon Woodlands had greatly increased, and they had obtained better things than before, but the expensive price of the Mist Dispelling Scroll made all Angel Corps players feel pained. Because the player selling the Mist Dispelling Scroll proposed to exchange two Mist Dispelling Scrolls for a flying mount, which was too black, but in order to speed up the exploration of Gryphon Woodlands, they had to submit.

As expected, after having the Mist Dispelling Scroll, their harvest was much greater, and unnecessary casualties were reduced a lot. All in all, this exchange was worthwhile, but they were really unwilling to be scammed out of a flying mount. The worst thing was that the flying mount that was scammed away fell into the hands of the enemy, which would be a greater loss than gain.

"It is said that the Mist Dispelling Scroll was made by a great mage. The person who sold the Mist Dispelling Scroll refused to say the specific details," a tall warrior next to him said. He was wearing a golden armor, which was a full-body armor. There was not a single gap at the junction of the armor, and it was natural. Many runes were engraved on it. He was the Angel Corps' number one berserker, Lie Yan.

Nie Yan knew that Angel Corps was exploring Gryphon Woodlands, but the Niu Ren Tribe's players couldn't get away to explore Gryphon Woodlands. The melee with the Mage Alliance would not end for a few more days. However, he also made very careful arrangements. First, he used the Mist Dispelling Scroll to lure Angel Corps, and divided a part of their dividends. Exchanging two Mist Dispelling Scrolls for a flying mount. Such a price was estimated to make Ang Yi Tian Shi want to hit the wall, but Ang Yi Tian Shi had to submit, because there was only one store selling Mist Dispelling Scrolls. In addition, Nie Yan asked Guo Huai to buy off two Angel Corps players at a high price, and recorded the entire process of Angel Corps exploring Gryphon Woodlands and transmitted it over. With these video materials, the Niu Ren Tribe would be able to achieve twice the result with half the effort when exploring Gryphon Woodlands in the future.

Ang Yi Tian Shi would never have thought that the Niu Ren Tribe was trading Mist Dispelling Scrolls with them, and they had handed over a flying mount to the Niu Ren Tribe, and the process of their exploration of Gryphon Woodlands was also recorded into a video and reached the hands of the Niu Ren Tribe. If he knew the truth, he would probably be so angry that he would vomit blood.
