I saw this person walking slowly with a pair of eyes shining with clear eyes, and I saw this person sitting cross-legged, with long hair hanging down to the ground, long eyebrows and beard, and his nose and mouth were covered.

The sunlight shone down from the wood, and the old man's face was full of flowers, and then his face was seen more clearly, and his hair was pale, not completely white, but for many years he had not shaved, and he was as furry and terrifying as a wild man.

This is the person in charge of the Yuan Qi Burst Array in Li Xiu's mouth, Master Dong Lan~!

"Master Dong Lan~"

Li Xiu, who also heard the footsteps, turned his head and bowed respectfully to this raunchy old man, although he was nearly sixty years old, but he was obviously still a middle-aged man, he saluted Dong Lan so freely and normally, and the respect from the heart even Meng Li couldn't help but look sideways.

"It turned out to be you kid, what's the matter, why don't you stay on it and run around?"

After hearing Li Xiu's voice, that Master Dong Lan raised his head hanging lazily, glanced at Li Xiu and Meng Li's group, and said with a smile.

"What, there's a guest coming?"

Different from Li Xiu's assignment to be stationed, Dong Lan, who had excellent ability, chose to 'come down' because he wanted to study the Yuan Qi Burst Array wholeheartedly, of course, the Yuan Qi Burst Array that had been preliminarily studied by the Han Imperial Family really did not disappoint him, and after his improvement, this Yuan Qi Burst Array was finally able to form a power against the enemy, so he was very familiar with the outside world.

"Yes, these guests want to see the power of our Yuan Qi Burst Array, please Master Dong Lan show us the power of this thing~!"

Slapped the heavy gun mount. Li Xiu, who pretended to be casual at Dong Lan and gestured to Meng Li and the others, said respectfully to this savage-like master.

At this moment, he doesn't see the slightest bit of power in his body~

"Hmm. Little Liuzi, go and prepare~! ”

glanced at Meng Li, a group of people in fresh clothes and angry horses. Dong Lan just said softly to the little attendant next to her.

For him, a crazy researcher, no one has anything to do with him anymore, so no matter how big Meng Li is, it has nothing to do with him, he doesn't want to leave such a natural research base, so he can maintain a mood that is not unhappy in the face of any powerful person.

"Yes, master~!"

The small attendant didn't pay attention to Meng Li's unusual person, and after listening to Dong Lan's instructions, he hurriedly walked to the small room that Dong Lan had just come out of.

"This thing was initially researched eleven years ago, and now it's about eleven years old~!"

Dong Lan, who had nothing to do, took two steps forward. Gently stroking the giant cannon in Meng Li's eyes like stroking his own child, a trace of love and pity appeared in the eyes of Dou Ding, who was covered by his long hair.

"The last time we used it was nine years and eight months ago, and at that time, both stability and power had been raised to the highest level by us, and the only thing that bothered us was this huge cannon body~! Of course, maybe for some people, weight is not an issue that can bother them~"

Dong Lan, who was slowly narrating the history of this vitality cannon, looked at this valley that would never see the light of day, and said indifferently.

When he heard that some people didn't care about the weight of this cannon, Meng Li naturally knew. This is the idea of those who have never been out of the valley at all, who do not know what the situation is outside, and in their opinion, this cannon is just a toy when they are idle. It's naturally good to be able to strengthen it slowly, and when the weight can't be solved now, it's better to continue to increase the power.

As everyone knows. The situation outside is urgent, if the weight problem cannot be solved. Then this vitality cannon will not be put into the battlefield, and then the research of these hundreds of years can be said to have ended in failure.

When the time comes. Even if it has been researched for decades, but the Han royal family no longer exists, and the result of hundreds of years is to make wedding dresses for others, and it is strange that the faces of the Han people can be better~!

"Nine years and eight months ago, it was right here, bombarded here," pointing to the depression that Meng Li had just noticed, this Dong Lan stroked his beard and exposed his mouth and said: "The pit there was made by that bombardment~!" ”

Looking at Dong Lan's gesture of talking with his beard at this moment, Meng Li smiled slightly, this old man is so interesting, and it is similar to the old naughty boy he once read in the book.

That old naughty boy is a lifelong lover of martial arts, and finally became a middle naughty boy who is raunchy, and this master Dong Lan is a lover of scientific research, and he also does not like trimming, and has devoted his whole life to this scientific research, this Dong Lan deserves his respect.

Although he is working for his hobby, after all, he has benefited the Han royal family, the Han army, and the Han Empire~!

"Of course, if it bombards into the enemy formation, I estimate that this cannon will be similar to the full force of a god of war, and it can form a damage of two or three hundred people~!"

Although Dong Lan is unkempt, he is not stupid, he clearly knows that Meng Li, the crowd, must be from the outside world, he is afraid that Meng Li will not know the power of this giant cannon, and he also vividly described it with numbers.

"Two or three hundred people~!"

Meng Li's eyes shrank fiercely when he heard this data, this number is not less~!

You must know that even if it was those powerful artillery pieces in the previous life, even if it was blown up into the pile, it would not be able to create the current level of damage~! It can be seen that the power of this vitality cannon should be far beyond his imagination.

Of course, needless to say, Meng Li also knows that such a high damage and the price must be small~

'As soon as the gun goes off, ten thousand taels of gold~! ’

Thinking of this ancient saying, Meng Li couldn't help shaking his head~

Although the price of this cannon may be unacceptable to him, for the sake of ambition in his heart, he still thinks that no matter how valuable a cannon is, it will not stop his determination to equip this vitality cannon.

Cannon, whether it is artillery or vitality cannon, is an epoch-making invention, with this thing and the original iron-blooded will, then the unification of the Han will never have any obstacles in front of him~!

"Master, these are three yuan crystals, please take a look~!"

While Meng Li was thinking, the little attendant ran over and handed over the three shiny glass-like balls in his hand to Dong Lan's hands. (To be continued......)
