It took a week for Sulun to clean up all the monsters around the gold mine, and the number of slaves in the gold mine increased to 6,000, of which the number of kobolds was the largest, with 2,000 people. The second largest number was the bear goblin, and there were underground orcs, big goblins, and taurens.

Six thousand slaves are currently enough, and some are sent to the mine to mine, and the other is sent to the road construction.

After Sulun and Kris cleared the gold mine, they began to explore further areas. Kris caught more than a dozen Death Knives beetles last time, and there must be a nest with Death Knives beetles around. Since they have decided to form a Death Knives beetle cavalry, this nest is naturally to be found.

Under Chris' order, these Deathkill beetles took two people back to their nests. The Deathkill beetles' nests were a little far from the gold mine. After walking for more than two hours, the two finally arrived at the Deathkill beetles' nests.

As expected, there are more than a dozen Death Knives beetles in this nest. Chris, who has already gained experience, easily controlled all the remaining Death Knives beetles.

Next, Chris directly moved the nest of the Death Knives beetle to the vicinity of Crete City. He wanted to let these Death Knives beetles reproduce here. He did not study much about the Death Knives beetle Sullen, and he didn't know whether this relocation could allow the Death Knives beetles to reproduce here smoothly. If not, he probably had to move back to his original place.

Leaving the task of forming the Death Knives Beetle Cavalry to Chris, Sulun left the underground world. After adapting for this period of time, he was preparing to upgrade the advanced iron bone to legend.

Back at the North Wind Tower, Sulun directly opened a retreat room, allowing the Galaxy to open the energy channel to connect the elemental pool. The element concentration in the retreat room increased rapidly. When he opened the system panel, Sulun found the high-level iron bone. Behind the high-level iron bone, there was a + sign flashing with a bright light. Sulun took a deep breath and directly chose to upgrade.

The next second, Su Lun felt like countless ants were biting, and the bones on his body seemed to be broken little by little and then merged again. This feeling came and went quickly. After all the pain disappeared, Su Lun finally breathed a sigh of relief.

The system's cold prompt sound also came from my ears.

"Ding, congratulations to the host, you used a little legendary skill point and successfully upgraded the advanced iron bone to the legendary iron bone. It was detected that the host has legendary strength and legendary toughness. The host's body triggered a special effect and obtained the talent: copper sheet iron bone."

[Legendary Iron Bone: After you have been tempered for thousands of times, your body has completely broken away from the boundaries of mortals and moved towards a higher level. The damage of ordinary attacks to you is reduced, your defense is increased by 50%. Attacks below 30 points cannot cause damage to you.]

[Copper and Iron Bone: With this talent, you will be immune to special effects such as disability, broken tendons, fractures, crushing, etc., and your spell resistance will increase by 20.]

Su Lun moved his body for a moment, and a crackling sounded like a thunderous beans. His current physical defense has become very strong. With the addition of talent such as legendary toughness, legendary iron bones, rigid bodies, etc., ordinary weapons can no longer cause damage to him.

Su Lun's skin became very tough. He took out an ordinary knife and scratched it on his body. However, no wound was left after the blade was cut. Finally, he continued to increase his strength and finally pierced the skin. As a result, the blood just flowed out a little, and soon the wound recovered under the talent of legendary regeneration.

After testing the changes in his body for a while, Su Lun did not leave the retreat room, but sat down again to restore his mood to a calm state. After a while, Su Lun took out a bottle of Nine-Turn Golden Pill from the storage bar.

When he opened the bottle stopper, a faint fragrance of medicine instantly filled the room. Su Lun took out a golden pill, and saw that the Nine-Turning Golden Pill looked golden, as if it was made of gold. Without hesitation, Su Lun raised his head and took the pill.

The Nine-Turning Golden Pill entered his abdomen, and soon a warm heat spread out from his body. Soon a gentle energy began to wander in his body. This energy was exactly the Nine-Turning Golden Pill he had just taken. Every time this energy wandered around the body, part of the energy would be integrated into his body.

After a few rounds, all the energy was completely absorbed by his body, and five free attribute points were added to his attribute bar. Sulun chose to add all five attribute points to agility, and the original agility value of forty-five points was instantly increased to fifty.

A stream of other energy flowed rapidly from his body for several times, and finally it was absorbed by his body. Su Lun keenly noticed that his body became more flexible. He took all the remaining four Nine-Turning Golden Elixirs, and there were twenty more attribute points on the attribute panel.

Su Lun's five-dimensional attribute power and agility have reached fifty points. This time he added the remaining attribute points to his spiritual physique and charm. Originally, his spiritual attribute was thirty-five points, and Su Lun directly added the fifteen-point freedom attribute points. His mental power also reached fifteen points.

The remaining five free attribute points and three points were added to his physique, and his physique also broke through fifty points. The last two attribute points were connected to the two free attribute points obtained in this upgrade, and all of them were added to the charm of his charm, and his charm also reached 31 o'clock.

Su Lun's physical fitness has changed dramatically after suddenly adding so many attribute points. Although he seems not much different from ordinary people now, he is actually more like a human-shaped tyrannosaurus with a 50-point strength and a physical fitness of fifty points. Ordinary dragons do not have such high attributes.

Even the most powerful red dragon among the five-colored dragons has not reached fifty when they are adults. For example, the weakest white dragon among the five-colored dragons, its power is even lower. In fact, the dragons in this world are very different from the dragons in previous games.

After all, the developers need to balance the game when making it. The strength of the dragon in the game in the institute was severely weakened. Simply put, the movement speed of the dragon. An adult red dragon has a size of more than 20 meters, but in the game, the flying speed of such a giant beast is actually 150 feet per round.

What is the concept of 150 feet? It is converted into meter, which is 45.72 meters, and it is less than fifty meters away. So how long is a round? The game sets one round in 6 seconds. One minute is divided into ten rounds. In other words, this giant beast with a size of more than 20 meters has a speed of only 7 meters/second in the sky. Not to mention flying, even humans can run faster than the speed of the dragon.

Look at its movement speed on the ground, the data is forty feet per round, which is more than twelve meters. After running twelve meters in six seconds, it is two meters in one second! What is this concept? Even if you have not been trained to catch a healthy young man, his speed of 100 meters can still run for fifteen seconds. If you want to convert it, you can run 7 meters per second.

Think about it, the dragon's body is more than 20 meters long, and it will be more than two meters away after taking a step. This data simply weakens the dragon into a fool.

Su Lun has never seen a real dragon, but there are still some data, and the difference between these data and the data in the game is not very big.

If you kill the dragon according to the attributes of the dragon in the game, it will basically be a delivery.

There is still a big difference between games and reality.
