When Wu Feng finished dealing with the tedious tasks of the day, it was already past lunch, but it was not the first time that he had not eaten lunch, he had long been accustomed to it, and he bought some snacks on the road to satisfy his stomach, and then came back to take a nap. Because this mission was very heavy, Hades Jiu didn't arrange some daily tasks that were too laborious and laborious for them.

After removing the barrier behind the mural, as soon as I stepped into the corridor, I heard a strange sound, like the fluttering of wings of birds.

"Is it Jeff teaching Liu Ye magic? What strange magic?" Wu Feng walked to the end curiously, and then... A few white shadows rushed towards him.

casually fanned aside a few white shadows that fluttered, Wu Feng saw clearly that these were letter birds, of course, there was nothing to be surprised by two or three letter birds, but... A room full of letter birds, isn't that a little too much? That neurotic has written hundreds of letters here?

His gaze was in the white flowers, a flock of letter birds, locked on the willow night... He was the only one in the room.

"Liu Ye, you wrote these letters, why did you write so many letters, and what about Jeff?" Wu Feng opened up a way and came to Liu Ye's side, with the word bewilderment written on his face.

"Oh... Jeffer, he's gone to fetch the letter bird, and will be back in a moment, and we're working on a new game for the letter bird... Usage. Liu Ye grinned, and then repeated his and Jeff's previous thoughts to him.

Wu Feng shook his head after hearing this: "The letter bird is affected by the material, even if you add any corrosion and curse magic on it, it can only leave a small part of the power, and every letter bird has to waste the mana consumed under normal circumstances to enchant, then relying on it to release a magic with complete power will be several times smaller than the normal situation, and the gains outweigh the losses, it is better to release the magic directly." Even if you take another 10,000 steps back, the letter bird must use spiritual power to imprint the recipient and the address, you can know the address when you fight, how can you know the name of the other party?"

Liu Ye nodded, admiring Wu Feng's thinking ability a little, but he didn't agree with his words, but asked rhetorically: "But we are idle now, the elemental power in the body is not consumed at all, and the elemental power also has an upper limit, so why can't you consume more elemental power in advance to make this kind of letter bird, as long as the recipient and address are empty, when the time comes, rest well before the mission, and the strength has not changed, but there is this kind of disposable weapon for nothing, isn't it very cost-effective?"

Wu Feng was stunned for a moment, then looked at him in shock and smacked his tongue...

"Moreover, we don't have to amplify negative magic, isn't it the same when positive magic is applied to teammates, anyway, the activation of the letter bird is very fast and very simple, almost does not consume mental power, as long as I am proficient, I can activate more than two hundred pieces in a minute, which is almost equivalent to fifty apprentice-level auxiliary magic." Liu Ye looked at Wu Feng's eyes and saw his shock, a little proud.

"It's a genius idea, but... It's impossible, magic is attached to a piece of paper, how can it hurt and save people? Have you ever thought about it?"

Liu Ye was silent, this is indeed the most difficult question, it is precisely because of this question that he and Jeff wasted so many letter birds, just doing experiments.

"We are experimenting, my ancestors have passed down an ancient secret art that can do it, but this secret art is biased towards inscription spells, it is a branch of space spells, and it can transform the existence of magic, so that the magic on objects can be transformed into energy forms, and it can make the letter bird aggressive. But... This secret technique... Requires a material called Mithril and a material called Dina Rock Ash, which is a bit of a money burner. ”

"You... Are you saying that you actually know about an ancient space spell?!And you mean it's just a lack of money, right?" Wu Feng's tone was a little uncalm.

Liu Ye nodded.

"Don't talk about it, let's go, we'll go and grab the letter bird now, you follow Jeffer to get it in the Hidden Temple, but the number should be limited... I'll go out to buy it, and I'll hand over the matter of the materials, and if the others come back after I come back, tell them about it, and I'll have a meeting tonight!" Wu Feng said quickly, turned around and left, looking a little anxious, as if he was afraid that he wouldn't be able to buy it if he was too late.

"It's shameless, it's obviously from me, and I put it on my face. "The ban on the poor road seems to be very dissatisfied with Liu Ye's behavior.

"Then do I say that I picked up this rare space-type magic, or do I just tell him about your existence?" This inscription transformation technique was indeed told to him by the forbidden canon, and he finally got the first powerful magic from its mouth, and directly helped him a lot... Although according to the forbidden canon, this is not offensive magic at all, it is like a blacksmith's craft... But he can use this craft to make offensive swords!
