"But if it's for the sword qi to be able to cut off the river, then every time I slash, I will increase the output of battle spirit power as much as possible...... In that case, wouldn't I be able to quickly exhaust my battle spirit power? ”

Carl asked with some puzzlement, after all, this is in the wild, as the most important battle spirit power of the war spirit warrior, once it is exhausted, no one knows what will happen.

He didn't want to just come out to practice sword fighting and put all his life into it.

Yi Ke pointed to the side with his hand, and specially instructed Carl to bring out the Karin machine gun, which was placed there safely.

"Train with confidence! When you are able to split the river with one sword, even if you haven't cultivated the Wind Sword Technique to the top, you can barely cope with it in ordinary battles! ”

Seeing Yi put on such a resolute attitude, Carl had no choice but to shrug his shoulders and come to the torrent with the blade of the wind spear.

"Hah!" Karl snorted, and the blade of the wind spear in his hand slashed in the direction of the torrent again.

Following the slashing action, a thick sword qi had already slashed straight towards the torrent. As soon as the sword qi entered the river, there was immediately a lot of river water diverted by the sword qi on both sides.

"Hmm...... It seems that there is really a possibility of flowing the water on both sides of the river...... "Carl looked at the sword qi with some satisfaction, and sighed lightly.

However, in the next second, when the sword qi traveled a certain distance in the torrent, after being consumed too much power by the river resistance, the sword qi actually dispersed directly halfway, leaving no trace in the turbulent river.

Carl looked at the middle of the river dumbfounded, he never thought that the first time he tried, he didn't even reach the other side of the river!

Karl, who was very unconvinced, slashed hard again, this time, the sword aura was thicker and the speed was even faster.

However, under the force of such a turbulent river, Karl's sword qi still did not succeed in reaching the other bank, and it dissipated again at a distance from the central region.

Burst!

Carl puffed out of his mouth in great depression, although he was extremely depressed in his heart, he also understood that this was because his sword qi had not reached the level it should have.

The attack of sword qi is nothing more than two aspects, one is the strength of sword qi, the stronger the output of the battle spirit power, the stronger the strength of the sword qi.

The other is the flight speed of the sword qi, which is also determined by the power of the user wielding the long sword.

And the factors that determine strength are usually human physical strength or power skills, but for these, Carl is currently lacking the most.

Carl actually understands this very well, so the training task that Yi put forward, even if it is outrageous, he will continue to train meticulously.

When he practiced the fast gun fighting technique before, he understood that if he couldn't lay a solid foundation for his basic skills, then he would never be able to lay a good foundation for his promotion.

Taking a deep breath, Karl looked calmly ahead, and once again slashed out the blade of the wind spear in his hand, and the sword qi came out in response......

Yi watched Carl in training silently from the sidelines, and now he can be regarded as a combination of Hurricane and Kidd...... There is both Kidd's slightly arrogant personality and Swift's extremely calm personality.

The combination of the two personalities also has an understanding and expectation of Carl.

However, because the wind is not at ease with Carl after all, the Yi after the fusion inherits the thoughts of the wind, and he still has a test mentality for Carl here.

Fortunately, in the past few days, although Carl's performance is not excellent, it can be regarded as making Yi Da accept his identity as a host from the heart.

When he saw that Karl naturally accepted the training task he had arranged, his heart began to be touched.

After a day's training yesterday, this morning Carl didn't even need his orders, and consciously walked to the side again for chopping training, and his heart finally began to accept Carl.

A self-disciplined and self-reliant host, no matter which spirit of war, will not dislike.

So at this moment, Yi Cai really fused the two war spirits of Kidd and Wind, and there was only one thought left in his heart - to make Carl stronger!

Training time always flies the fastest, and by the time the sun slowly sets, Carl is too tired to say a word.

In fact, after he continued to train for several hours, the battle spirit power in his body had completely bottomed out. Without the blessing of battle spiritual power, the sword qi suddenly couldn't be released.

"Keep training and work on your physical abilities!" Yi De's voice sounded extremely punctually, allowing Carl to continue his chopping training when his battle spirit power was exhausted.

Compared to yesterday, Carl now even had to endure the constant feeling of weakness in his body, while forcibly waving his arm and slashing forward again and again.

Fortunately, no matter how hard it was, Carl still persevered in this training.

The result was that the spiritual power in his body was completely empty, and his arm was swollen again, if it weren't for the fact that his spiritual power was different from ordinary people, I am afraid that he would have fainted during training.

"Whew...... Ha ......" Carl gasped and sat on the ground, looking at Yi Yi and said tiredly: "I have exhausted my battle spirit power now, is there any way to repair my damaged body?" ”

Yi Hehe smiled, shook his head, and said, "Don't worry, when you are resting, the battle spirit power recovered in your body will give priority to repairing your damaged body." ”

After receiving a positive reply, Carl breathed a sigh of relief, took some dry food with difficulty with his left hand, and after eating it hastily, he quickly fell asleep.

Yi did not object to Carl's choice, in fact, the state of human sleep is used to repair the body and restore physical strength.

Moreover, if the warrior needs to quickly recover his battle spirit power, he also needs sleep to recover.

In the distance, the sky finally darkened again, and during the past two days, Carl had also turned on the radio to contact Leo and John, and after learning that there was nothing unusual, he was also relieved to stay.

Yi, who was originally sitting quietly next to Carl, suddenly changed his expression, and looked at Carl a little inexplicably, who was suddenly flooded with a hazy silver halo all over his body at this time, occasionally with a hint of cyan light, which was also speeding along his whole body.

"It's pretty good...... Using this training method, he can quickly increase the frequency of his use of battle spirit power, and then repair his physical body through the recovered battle spirit power......"

"It can not only increase the condensation of the battle spirit power in his body, but also increase his control over the battle spirit power...... I believe that after this cultivation is over, his skyrocketing battle spirit power will not only be completely controlled, but he should also be able to touch the threshold of 4 spirits. ”

Yi looked at Carl with satisfaction, and felt an extremely sense of accomplishment for the cultivation method he had chosen for Carl.

It's just that neither he nor Carl noticed that there was a figure in a big tree not far away, quietly observing them.
