The old butler shook his head with a sigh and walked away.

At this moment, Wu Zhi had been hiding behind the window sash, his eyes scanning the surroundings sharply, not wanting to let go of any details.

Finally, the hard work paid off, and he saw a swaying figure behind the jungle not far away.

In a flash, it's extremely fast.

"Hehe, let me guess correctly, sure enough, someone is secretly playing ghosts."

Wu Zhi thought left and right, he had nothing to do and was not in a hurry, so he simply stood inside the threshold with his hands on his chest, and looked out through the flying curtains.

Of course, he didn't stand for long.

When the old housekeeper had completely left and the person he was following had disappeared, Wu Zhi finally went to the martial arts training ground in the backyard of Hujiazhuang.

This time, he arrived at the place smoothly and saw several soldiers who were already fully dressed.

That's right, the ones who specialize in shells.

Everything is in line with that sentence, people rely on clothes, horses and saddles, and now they just take a little bath and change into clean clothes, and everyone who is disgraced just now has changed their appearance.

At least it looks like a human figure.

"Yes, it's pretty much the same now, are you ready? Master Cai will come over to inspect it in a while! ”

Wu Zhi raised an eyebrow and asked.

The next moment, there was a deafening answer, and everyone's voices were in unison.

"Get ready!"

"Then I'll see, you'd better not let me down."

……

Half an hour later.

Wu Zhi took Cai Jing, who had woken up, to the open space in the backyard together, and saw several people standing in unison.

"Lord Cai, this is the expert I have specially cultivated, who knows how to make cannonballs!"

"Oh? Can you give me a live demonstration of the power of their shells? ”

Cai Jing is sitting in Bianjing, he is a person who has seen strong winds and waves, and he has actually seen the power of artillery, but today for some reason, there is a kind of curiosity that makes the gods worse.

And for Wu Zhi, such an opportunity is unwanted.

He glanced at the surrounding environment, but still felt that it was not suitable here, and if it didn't work, he would blow up Hujiazhuang.

Or it's not good to hurt Cai Jing, and he can't afford to take responsibility at all.

"Lord Cai, let's go to the nearby mountains to toss, if we test the power of gunpowder in the Zhuangzi, and leave aside the matter of compensation for the time being, I'm afraid that hundreds of people will have to be covered by heaven and earth tonight."

Wu Zhi smiled helplessly.

Seeing this, Cai Jing is still more reasonable, and he doesn't have a bad brain.

So, the group took the carriage loaded with gunpowder and went to a remote mountain forest outside Zhuangzi.

Wu Zhi chose the site as quickly as he could, right next to a river, surrounded by almost all large rocks, with very few weeds and trees, so as to avoid the final self-defeating and set fire to the mountain.

Even so, he was still a little uneasy, and before starting to act, he stood on the stone and shouted a few times at the surroundings.

After making sure that there was no echo in the valley, I finally put my mind at ease.

"Lord Cai, for the sake of your health, I suggest you cover your ears, otherwise you will be guilty for a while."

"Okay."

Cai Jing agreed happily, and then covered his ears.

And the entourage who followed him was the same, after all, this guy had been waiting in the mansion for a long time, and he had never seen such a big scene, and now he finally met once......

In addition to nervousness, in fact, it is more exciting.

"Fire!"

Wu Zhi gave an order.

In the distance, by the river, the people who had been waiting for a long time finally heard the sound, and immediately lit the torch in their hands, lit the fuse, and then ran to the crowd like they were desperate.

When they finally came running, they just didn't have time to gain a foothold when there was a violent vibration behind them.

All of a sudden, the gunpowder exploded!

Accompanied by billowing smoke, a heat wave hit, and a column of water five or six meters high exploded on the horizontal plane, which did not look ordinary and spectacular.

There is even a kind of posture of the sky falling!

Wu Zhi skillfully squatted on the ground with his head in his hands, waiting quietly.

After a while, everything died down.

Only then did he stand up and take a look at his surroundings, and after confirming that several gunpowders had all exploded, he was relieved, but fortunately there was no scandal at the scene.

Everything is going well.

"Lord Cai, okay, look at the place just now, do you feel satisfied with the traces after the explosion?"

Wu Zhi said with a smile.

Hearing this, Cai Jing put down the hand covering his ears little by little, and then raised his eyes to look at the river.

I was instantly shocked by the marks after the explosion!

The water's edge, which was quiet and peaceful just a moment ago, is now a mess, and a large crater at least ten meters deep has been blown out, and the river is spreading little by little.

The scene was so shocking that Cai Jing didn't react for a while.

In a moment.

"I have to say, Wu Zhi, you are indeed very capable, even the people you guide can make such a powerful gunpowder, if you personally go down to develop it, then what height will it reach?"

Cai Jing asked with a smile.

Compared with before, the tone is obviously much softer.

Wu Zhi knew that he had conquered the entire old fox with his strength, but he must not be proud at this critical moment.

You must know how to advance and retreat!

"Lord Cai has won the prize, as long as you like it, if you have a chance in the future, if this gunpowder can be used on the battlefield, it is also a sharp weapon to expand the territory!"

"Indeed."

After speaking, Cai Jing nodded, and continued to look at the river thoughtfully.

Wu Zhi was immediately silenced.

The air was quiet, as if it had been quiet all along, and there had never been a loud noise, but the devastation by the river was undoubtedly the best proof of this.

However, this tranquility did not last long before it was interrupted by a burst of cursing that broke through the air!

"Hehe, after staring at it for so long, I finally got the chance to be alone!"

"Cai Jing, you dog official, I must kill you today to avenge those resentful souls who died in vain, in order to comfort their souls in the sky! Otherwise, it will be difficult to solve the hatred in my heart! ”

"And you, Wu Dalang, I originally thought that you were actively suppressing bandits and a rare good person, but now it seems that you are a co-currant person, so you should be a companion on Huangquan Road surnamed Cai!"

Before the words fell, the murderous spirit had arrived.

The look in Wu Zhi's eyes suddenly turned cold, and when he looked up, he saw a person dressed in black and coming straight to his life.

He frowned.

Countless thoughts flashed through my mind, if the people who came to ambush and assassinate them today were righteous people, it would be too cruel to kill them by themselves......

However, before Wu Zhi had time to think about it, he was forced to fight in desperation.

The soft sword he carried with him flew up and down, and the cold light was pressing.

By chance, the mask of the man in black was torn off and drifted away with the wind.

Wu Zhi finally saw the true face of Lushan who was fighting against him! My mind suddenly changed!
