Chapter 1031 Great Dan King Realm

At this moment, Su Chen slowly overcame this feeling of discomfort, and the speed of his sword was getting faster and faster.

However, the faster the sword was, the greater the burden on Su Chen himself. Every time he drew a sword, the pressure on Su Chen himself because of the sword technique was getting greater and greater, and every bone in his body was clanging.

But at the same time, Su Chen's sword speed was also getting faster and faster at a speed visible to the naked eye.

If someone was observing Su Chen practicing sword, they would find that Su Chen's sword would be faster every day. At the beginning, the sword light of Su Chen could be caught by the eyes of ordinary people, but gradually it was completely impossible to catch.

Imagine that even the sword light could not be seen, and the sword would reach the enemy's throat at the moment of raising the hand. How terrible it was.

After a whole month, Su Chen finally made some progress in "fast sword".

However, this fast sword technique was only the first entry requirement of the Five-Colored Phantom Thunder Sword. A little success in this could only mean that he had touched the threshold of the Five-Colored Phantom Thunder Sword.

However, Su Chen was already very satisfied with touching the threshold. After all, the Five-Colored Phantom Thunder Sword is an imperial technique, and it is definitely a long road to practice. It is impossible to become fat in one go.

Swish, swish, swish!

Su Chen swung the broken sword of the Martial Emperor to his heart's content, fully displaying the first level of the Five-Colored Phantom Thunder Sword.

Suddenly, he felt something surging in his body, and after careful sensing, he was immediately delighted.

"It's the eleventh sword energy!"

Most people would be considered perfect if they practiced to the tenth sword energy, but there are also geniuses who can practice to the eleventh and twelve sword energy. For Su Chen, he would not choose to condense the sword intent when he had ten sword energy, but would choose to push the number of sword energy to the extreme first, and then condense the sword intent, so that the power of the sword intent would be stronger.

Now that the eleventh sword energy has begun to condense, he has achieved his wish.

At that moment, Su Chen immediately unfolded the Five-Colored Phantom Thunder Sword, and after the ten sword energy was slashed out, he saw a new sword energy sprouting. Although this new sword energy is much weaker than the other sword energy, it is also the real eleventh sword energy.

"Haha!" Su Chen felt even happier, waving the broken sword of the Emperor Wu in his hand. Soon, the eleventh sword energy became stable, and it was on par with the other ten sword energy, exerting its due power.

Eleven sword energy and ten sword energy, this is a qualitative leap, equivalent to taking a big step.

Su Chen was refreshed. This time he not only learned the secret art of the Emperor Wu, but also condensed eleven sword energy, which can be said to be a double happiness.

At that moment, Su Chen ended his closed-door training and planned to leave the mustard seed space.

However, before that, he still had to deal with the few pieces of Lei Jiao stone he got in the Emperor Wu cave.

At that moment, Su Chen took out a few pieces of Lei Jiao stone. These pieces of Lei Jiao stone, weighing dozens of kilograms, belong to the seventh-level precious gold.

Precious gold is a general term for materials specially used to upgrade magic weapons. These materials usually contain a lot of spiritual energy, so they are suitable for improving the grade of magic weapons.

The seventh-grade precious gold means that the grade of the sixth-grade divine weapon can be upgraded to the seventh-grade, or the grade of the seventh-grade divine weapon can be upgraded to the seventh-grade and a half.

For Su Chen, the arrival of this Lei Jiaoshi can be said to be a timely help, which can just upgrade the grade of the Sun-Destroying Bow and the Black Crystal Iron Arrow.

At this moment, Su Chen took out the Sun-Destroying Bow and the Black Crystal Iron Arrow, and called Xiao Tianhuo over.

Now he has not opened the layer of the fire attribute of the mustard space, so if he wants to melt the seventh-grade precious gold, he has to borrow the power in the body of Xiao Tianhuo.

Su Chen's mind moved, and the power in the body of Xiao Tianhuo was extracted by him and fused into his own Danhuo. This is only in the mustard space. If it is in the outside world, it is absolutely impossible to operate so roughly.

Seeing that Xiao Tianhuo was instantly depressed after the energy was extracted, Su Chen was a little bit reluctant and comforted him: "I will refine a pill to enhance your soul power for you later."

Xiao Tianhuo nodded, yawned, and lay down to sleep.

Su Chen controlled the Dan fire to melt the Lei Jiao stone and extract the essence.

To completely extract the essence of this Lei Jiao stone, it needs to be melted at high temperature twenty times.

Although these Lei Jiao stones weigh dozens of kilograms, in fact, when Su Chen completely extracted the essence, it was only a fist-sized piece.

Su Chen integrated the extracted Lei Jiao stone essence into the Sun-Destroying Bow and the Black Crystal Iron Arrow.

The Sun-Destroying Bow and the Black Crystal Iron Arrow were also successfully upgraded from the sixth and a half grade to the seventh and a half grade.

Moreover, the Black Crystal Iron Arrow that fused the essence of Lei Jiao stone actually carried a trace of lightning power. This means that the person shot by the arrow may have a short-term muscle paralysis.

In actual combat, this trace of lightning power is undoubtedly very effective, and it may even change the situation at a certain time.

This result made Su Chen very satisfied.

Finally, there was still a little essence of the Lei Jiao Stone left, and Su Chen also used the Lei Jiao Stone to fuse the Ice Soul Sword, upgrading the Ice Soul Sword from a seventh-grade divine weapon to a seventh-grade semi-divine weapon.

However, the Ice Soul Sword did not inherit the lightning power of the Lei Jiao Stone, which was normal. Not every smelting can give a specific attribute to the Ice Soul Sword.
