In Meng Li's opinion, the yuan crystals in the mouths of the three little attendants are an enlarged version of the glass balls, and the slippery surface and the seemingly hazy interior give Meng Li an extremely dangerous foreshadowing, this thing will really hurt if touched~!

Moreover, if Meng Li is not mistaken, then these three element crystals should also be different, because although they seem to be about the same size on the surface, they are not the same on the inside.

Just like two human fists hugging each other, the big meta crystals look different from each other is that their internal differences are too great, and the hazy aura circulating up and down the surface is dense and thin, so that people can see the difference at a glance.

"This meta crystal is a kind of ore with a better ability to store vitality, of course, even if it is the same thing, he also has good and bad points, the inner space is large, and the vitality that can be filled with a large space is naturally thicker, and the inner space is small, and it is naturally filled with less vitality, so it seems a little transparent~"

After taking out the thinnest yuan crystal from the arms of the little attendant, Dong Lan, who was holding the yuan crystal and shining it in the sunlight for a while, gently stroked the large glass ball twice.

"This relatively low-level meta crystal is also the least powerful, which is equivalent to the full force of a first-class general~!"

As she spoke, Dong Lan slowly approached the side of the Yuan Qi Cannon while holding the Yuan Crystal in her hand, as if she wanted to show his power to Meng Li.

"Click~"

On a line that Meng Li didn't pay attention to, I saw that after Dong Lan lightly pressed it, a metal piece popped out there, and below, it was a spherical space that was not big or small, just enough to accommodate a metacrystal. This is the entrance to this otherworld's Genki cannonball.

"Ding Dong~"

Dong Lan, who gently placed the yuan crystal in his hand, also did not stop the crisp ding dong sound, which was the clear sound of the ore hitting this mysterious metal.

"Bell~"

Dong Lan, who gently covered the metal sheet, walked directly behind this Yuan Qi cannon, and motioned to Meng Li and the others to dodge the surroundings of this Yuan Qi cannon, and be careful of danger.

Meng Li, who cherished his life very much, did not pretend to be a hero who was not afraid of death at this moment, and after answering the order, he took a big stride and walked in the opposite direction of the Yuan Qi cannon.

"The firing range of this thing is more than twice that of the strongest Qin crossbow. In other words, there is a distance of about more than 2,000 zhang~! Of course, if you adjust the angle of the muzzle, then the range from 50 zhang to more than 2,000 zhang can be included under the threat of the muzzle, but adjusting the angle of this thing is also a difficult thing, which requires specialized talents to loosen the place connected to the base, and then adjust it according to the pattern direction of this formation~"

patted this big guy who almost spent his whole life's effort, Dong Lan at this moment can be described as having mixed feelings~!

"If you don't succeed, you will become benevolent~! If I don't become the behind-the-scenes hero of Dahan. Then you will become the mastermind behind everyone's propaganda~! ”

Thinking about the situation after the battlefield, Dong Lan sighed for a while, if the Han army won and finally unified the Blue Continent again, then he Dong Lan would inevitably be remembered on the monument of history; On the other hand, if the Han army fails, then he who invented this killing weapon on the battlefield will be engraved by the enemy in the textbooks that destroy mankind and destroy history. The difference between this positive and negative is endless.

"This thing. It takes at least thirty breaths to recharge the metacrystal, to gather the energy on its own, and then to launch. ”

A group of people followed Dong Lan's gaze to look at this vitality cannon that began to brew its own power, and the momentum it emitted made everyone can't help but tense their bodies, this thing. It's really amazing~!

"What?"

Meng Li, who pretended to have an indifferent expression, exclaimed when he heard that each shot would take only thirty breaths, that is, only one minute to die.

You know, whether he looks at it from the novels of the other world, or the history of China. The firing speed of that cannon, or the magic crystal cannon, has always been a big problem, and now this thing can reach a cannon in less than a minute, thinking about the power of that cannon, Meng Li is a burst of joy.

"But don't rejoice, although the speed of the launch is not restricted, but this thing has a big shortcoming, or it is a lack of our ability~!"

After looking at the happy expressions of the people from the outside world after hearing the information in their words, Dong Lan had to pour some cold water on them to let them know the shortcomings of this thing.

"What are the drawbacks?"

The power is big enough, and the rate of fire is not restricted, if this is filled with the most dense meta crystal, it is equivalent to one after another God of War is constantly releasing his full strength, no more, only ten such Yuan Qi cannons, each cannon is enough to give five rounds, even if the enemy army has more people, but under the heavy casualties and psychological blows, it is not a morale-boosting opponent of the Han army~!

Therefore, in Meng Li's opinion, this Yuan Qi cannon has almost no other shortcomings except for its weight.

"Weight is a problem, that is, it is still impossible to move now, in addition, maybe our ability is not enough, maybe the material is not good, this cylinder can accommodate up to two attacks of the God of War level~! If you change it to the Battle Venerable level, you can increase it to six to eight attacks, and the War King level attacks can be close to twenty~! If this limit is exceeded, then this vitality cannon will be in danger of exploding~! ”

Dong Lan's words poured a large basin of cold water on the happy people, okay, the rate of fire and power are there, but you said that the material of this cannon itself is not good, and the maximum ability to fire is limited, so you might as well tell me that this thing is just a one-time thing~!

Meng Li, who complained in his heart, had to look at such a gorgeous vitality cannon again, and that look of regret made everyone present feel deeply.

"But you can't force it, just treat him as a one-time open-path weapon~!"

Meng Li, who shook his head, knew his shortcomings, but he was still looking forward to how invincible he would be on the battlefield. (To be continued......)
