Although Song Yu relied on the advanced vine rejuvenation technique to win the exchange meeting, he didn't know much about this spell, so he still needed to comprehend, only in this way could he give full play to its power.

How powerful is this spell?

After all, the battle between life and death is not a point at the exchange meeting, if life is in danger, no one will care about chrysanthemums, and no one will care about face, just kill the enemy.

It is precisely like this, Song Yu carefully observed the tiny vines on his fingertips, the objects condensed by the aura, exuding a faint green, even if it was a small one, it still gave people a feeling full of vitality.

In the moonlight of the bright moon, the tiny vines resemble swaying aquatic plants.

"How can we test its power?"

Song Yu's eyes showed a look of contemplation, this spell is not like other spells, just put it on the ground, and the other party must be a creature to cast the spell.

It's impossible to use the flying demon beasts outside the Nantian Gate for experiments, right?

You can't experiment on your own, can you?

If you don't control it well and blow up your chrysanthemum, you will completely become a laughing stock in the immortal cultivation world.

"That's right!"

Song Yu suddenly slapped his thigh, thinking of Zhou Qingfeng, he had asked Zhou Qingfeng to experiment with spells before, but thinking that Zhou Qingfeng was going to be busy tonight, he was too embarrassed to disturb.

So he found Xinglou, and after the other party knew his intention, he closed the door and didn't chase him out to teach him a lesson, which was already good.

Since Xinglou was unwilling, Song Yu had no choice but to find Zhang slowly.

The other party was practicing swords in the courtyard, and when he saw his arrival, a smile appeared on his face.

"Little junior brother, what are you doing at such a late hour?"

"I ......" Song Yu thought about it, and it was difficult to speak, Zhang was a girl, and it didn't seem wise to look for her.

You won't be beaten, you will only be stabbed twice.

"It's okay, I'm your senior sister, what's not to tell me?" Zhang slowly saw that Song Yu was about to speak and stopped, and said softly.

"This ......" Song Yu didn't want to give up again, thought about it, and said slowly, "Senior sister, I want to experiment with my spells, but the second senior brother and the third senior brother are not available, so I want to ask you if you have time? That's all, I don't mean anything else." ”

"Yes. Zhang slowly didn't get angry, but said seriously, "I also want to see why your spell, the vine rejuvenation technique, a healing spell, turned into a sword technique in your hands?"

"Thank you, Senior Sister. Song Yu said gratefully.

He found that Senior Sister was really special, as long as it involved in cultivation, she would be extremely serious and would not have other thoughts.

Could it be that Senior Sister is also a cultivator?

"No, let's get started now!" Zhang said slowly.

The two stood in the middle of the courtyard, and Zhang slowly suppressed his strength to the same as Song Yu, and first took a look at the power of Song Yu's spell.

Now that he had Zhang's approval, Song Yu no longer delayed, and the aura in the dantian flowed, and a vast energy flowed along the meridians in the body, forming a small green vine on his thumb.

The moment the tiny vines appeared, Zhang slowly showed a contemplative look in her eyes, and she could clearly feel the sword qi contained in it by feeling this energy up close.

This is a very immature sword qi, but it already has a very strong power.

"Senior sister, be careful. Song Yu shouted in a low voice.

In the process of Zhang slowly thinking, the tiny vines of Song Yu's thumb had already condensed into a ball of light in his hand, and as soon as his voice fell, he slowly smashed straight towards Zhang.

Zhang nodded slowly, did not resist, at the moment when the ball of light invaded her body, she felt that immature sword qi, with the blessing of green energy, as if she had taken a tonic, followed her meridians, like a tiger descending a mountain, and rushed towards her chrysanthemum.

Sword Qi and Green Energy complement each other, is one plus one greater than two?

That's a bit interesting!!

Zhang slowly did not panic in the slightest, and his strength suddenly increased by one level, and he came to the middle stage of foundation building, and resisted all of Song Yu's attacks.

This process didn't take much effort.

"Senior sister, are you alright?"

Song Yu looked at Zhang slowly nervously, and when he saw Zhang slowly, he thought there was something bad?

"It's okay, it's just that the power of your spell is a little wrong, it's much worse than the power in the exchange meeting, are you sure you used all your strength?" Zhang said slowly and suspiciously.

Just now, she was ready to use the Yuan Infant Stage Cultivation to resist Song Yu's spell, but she didn't expect that she would solve it with only the strength of the middle stage of foundation building, which was really incomprehensible.

"Yes, I didn't keep my hand, could it be that Zhang San was exhausted at the time, so I was able to cause so much power, and now I can't do it?"

At present, this spell has the power to fight with the monk in the middle stage of foundation building, which already looks very good, after all, he is only the strength of the early stage of foundation building, but he also found that something is wrong.

The moment he cast the spell just now, he didn't have the unstoppable feeling of the exchange meeting, which was very strange.

"That's not right, it shouldn't be just this bit of power, if you think about it, what else is there to ignore?" Zhang slowly reminded.

"I think about it. ”

Song Yu paced and thought, recalling the exchange meeting and the current spell casting process, Zhang slowly did not bother, but waited patiently on the side.

Of course, she can let Song Yu speak out and everyone will find the answer together, but in this case, it will affect Song Yu's perception effect.

This is Song Yu's spell, and only when Song Yu figures it out himself, can he get the biggest gain.

Suddenly, Song Yu seemed to have caught something in his mind, and said in surprise: "That's right, the fingers I cast spells are different, in communication, I use the index finger, and now I use the thumb, only for this reason, the others are exactly the same." ”

"Is there a problem with the fingers?" Zhang was slowly stunned, and then said, "Okay, let's give it a try, then we'll know." ”

"Okay!" Song Yu nodded.

Next, Song Yu used his index finger to cast a spell, and an unstoppable feeling had filled his heart at the moment when the aura was mobilized in the dantian, and as a green ball of light flew out in his hand, this feeling reached its peak.

And sure enough, it worked!!

Zhang slowly turned pale, and directly used the strength of the late stage of foundation building to greet him, but he still underestimated the green ball of light, and the green ball of light broke through the layers of defense in the blink of an eye, and he was about to succeed.

"Kill!" Zhang slowly shouted softly, a killing intent erupted in his body, instantly extinguishing the power of Song Yu's spell, as soon as it appeared, it seemed to kill everything, without the slightest vitality.

This is complete annihilation, as long as the killing intent is shrouded, no living thing can survive.

"What a powerful sword qi!"

Song Yu's face changed, it was the first time he felt Zhang's slow sword qi, no wonder the senior sister stood alone in the world, the younger generation had no opponents, I was afraid that it was a fragile person, and in the face of this sword qi, the weapon in his hand could not be held.

"This is not sword qi, but sword intent. Zhang said slowly and seriously, "Junior Brother, the gap between sword intent and sword qi is like the sky and the earth, but in the current situation before, it was only a matter of time before you condensed your sword intent. ”

"Uh......" Song Yu was slightly stunned, "But I'm just a priest, I don't want to be a sword cultivator!!"

"Why don't you want to?" asked Zhang slowly and curiously.

"I have always liked to develop obscenely, and make a fortune in a muffled voice, which is too far from the chic freehand of swordsmanship, there is no return, and I can't become a sword cultivator at all. Song Yu said truthfully.

In his opinion, whether it is a sword cultivator or a priest, as long as it is in line with his own path, he will choose, and his choice to become a priest is based on this consideration.

"You misunderstood, it's just one kind of sword cultivation, and there is another kind of sword cultivation that is a slut, such as a master, but I won't advise you to become a sword cultivator, because you are already a sword. Zhang said slowly.

"Really?"

"Yes, it's just that your sword way, I can't understand it, you don't have to care, go on according to your own heart, you can always see your sword intent. ”

"Thank you, Senior Sister, for your advice!!"
