Tianyu Alchemy Lord

At the moment, Su Chen slowly overcame this uncomfortable feeling and drew his sword faster and faster.

However, the faster the sword was drawn, the greater the load on Su Chen. Every time the sword was drawn, the pressure on Su Chen himself due to the sword technique became greater and greater, and every bone in his body was clanking.

But at the same time, Su Chen's sword drawing speed was getting faster and faster that could be seen with the naked eye.

If anyone is observing Su Chen's sword practice, he will find that every day, Su Chen's sword drawing speed will increase by one point. At first, ordinary people's eyesight could still catch Su Chen's sword light, but gradually they couldn't catch it at all.

Just imagine, you can't even see the light of the sword, but the moment you raise your hand, the sword reaches the enemy's throat. How terrifying that is.

A full month later, Su Chen finally achieved some success in "Quick Sword".

However, this quick sword technique is only the first level entry requirement for the five-color phantom thunder sword. A small success in this can only mean that you have touched the threshold of the five-color fantasy thunder sword.

However, when he touched the threshold, Su Chen was already very satisfied. After all, the Five-Color Magic Thunder Sword is an imperial art, and there will definitely be a long way to go before practicing it. It is impossible to become a fat man in one sitting.

Swish, swish, swish!

Su Chen wielded the Martial Emperor's Broken Sword to his heart's content, fully displaying the first layer of the five-color phantom thunder sword.

Suddenly, he felt something surging inside his body. After carefully sensing it, he suddenly felt happy.

"It's the eleventh sword energy!"

Most people are considered perfect when they have cultivated the tenth sword energy, but there are geniuses who can cultivate to the eleventh or twelve sword energy. For Su Chen, he would not choose to condense the sword intention when there are ten sword qi, but would choose to push the amount of sword qi to the extreme first, and then condense the sword intention. In this way, the power of the sword will also increase. Stronger.

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

At that moment, Su Chen immediately unfolded the five-color phantom thunder sword. After ten sword qi were slashed out, he saw a new sword qi budding. Although this new sword energy is much weaker than other sword energy, it is still the real eleventh sword energy.

"Haha!" Su Chen felt even more happy and waved the Martial Emperor's Broken Sword in his hand. Soon, the eleventh sword energy became stable, juxtaposed with the other ten sword energies, and exerted its due power.

Eleven sword qi and ten sword qi are a qualitative leap, equivalent to taking a big step forward.

Su Chen felt refreshed and refreshed. This time he not only learned Emperor Wu's secret technique, but also condensed eleven sword energies. It was a double blessing.

At that moment, Su Chen ended his retreat practice and planned to leave the Mustard Seed space.

However, before that, he still had to deal with the few Thunder Jiao Stones he obtained in Emperor Wu's Cave.

At the moment, Su Chen took out several pieces of Thunder Jiao Stone. These thunderstones weigh dozens of kilograms and are seventh-level precious gold.

Precious gold is the collective name for materials specially used to upgrade divine weapons. These materials usually contain a large amount of spiritual energy, so they are suitable for improving the level of divine weapons.

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

For Su Chen, the arrival of the Thunder Jiao Stone was a timely help, just enough to upgrade the Sun-Destroying Bow and the Black Crystal Iron Arrow.

At that moment, Su Chen took out the sun-killing bow and black crystal iron arrows, and called Xiao Tianhuo over.

Now he has not activated the level of mustard space fire attribute, so if he wants to melt the seventh-level precious gold, he has to borrow the power from Xiao Tianhuo's body.

With a thought in Su Chen's mind, the power in Xiao Tianhuo's body was extracted by him and merged into his own Dan Fire. This means that in the mustard space, if it were outside, it would be absolutely impossible to operate it so roughly.

Seeing Xiao Tianhuo's sluggish appearance after his energy was extracted, Su Chen couldn't bear it 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 its essence.

To completely extract the essence of this thunderstone, it needs to be smelted at high temperatures twenty times.

Although these pieces of thunderstone weighed dozens of kilograms, in fact, when Su Chen completely extracted the essence, they were only the size of a fist.

Su Chen integrated the extracted thunderstone essence into the Sun-Destroying Bow and black crystal iron arrows.

The sun-destroying bow and black crystal iron arrows were also successfully promoted from the sixth and a half grades to the seventh and a half grades.

Moreover, the black crystal iron arrows that were fused with the essence of thunderstone actually contained a trace of thunder and lightning power. This means that a person hit by an arrow may suffer temporary muscle paralysis.

In actual combat, this power of thunder and lightning is undoubtedly very effective, and may even change the situation of the battle at certain times.

This result made Su Chen very satisfied.

In the end, there was still a little bit of thunderstone essence left, so Su Chen fused the Ice Soul Sword with thunderstone, and upgraded 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 thunder and lightning power of the thunderstone. This is normal. Not every smelting can give specific attributes to it.
