When all the guards had descended the mountain and were ready to move on, the problem arose.

The boulders that rolled down had blocked the way ahead.

Yao Guangxiao immediately stood in front of the boulder pile and said with a solemn expression: "It seems that this is the real purpose of that group, they don't want to kill our people, they just want to block our way!" ”

Zhu Di was on Yao Guangxiao's left side and sneered: "It's just a boulder, just move away, what's so difficult about this?" ”

"No!"

Yao Guangxiao dissuaded: "Lord Wang, this boulder has a loose structure, if it is moved rashly, it is likely to cause the boulder to roll again and hurt the guards!" ”

Zhu Di was stunned for a moment, and then his face became ugly.

Yao Guangxiao said very reasonably, this boulder really can't be moved at will.

"So what do we do now? Take a detour? ”

Zhu Di frowned and asked Yao Guangxiao.

Yao Guangxiao shook his head and said: "This is not possible, if you take a detour, you will have three more days of marching time!" We don't know when the Northern Yuan army will arrive in Fengtai, in case we arrive, the Northern Yuan people have already occupied Fengtai, then we will be in trouble! ”

Zhu Di suddenly said angrily: "This blue jade is really not a thing, it is just a matter of framing this king, how innocent is the people of Fengtai, they will suffer the danger of being ravaged by the iron hooves of the Northern Yuan!" ”

Yao Guangxiao agreed: "Lan Yu is indeed too ruthless, now that our road ahead has been broken, we still have to find a way as soon as possible." ”

As if thinking of something, Zhu Di glanced behind him, and then looked at Yao Guangxiao and said: "Before leaving, Mr. He asked me to bring twenty cannons, saying that this cannon is very powerful, maybe we can use artillery to blast these boulders away!" ”

"With artillery?"

Yao Guangxiao hesitated: "Artillery may have a lethal effect on flesh and blood, can it have an effect on these boulders?" ”

Zhu Di nodded and said: "It should be no problem, Mr. He said that twenty artillery pieces can be fired in unison, which can flatten a mountain!" ”

Yao Guangxiao couldn't help laughing and said: "This is a bit too exaggerated, how can the power of artillery be so great!" ”

The artillery of the Ming Dynasty was basically based on solid bullets, and the power was indeed not particularly large.

The people of the Ming Dynasty were also not deeply aware of the power of zhayao, so it is not surprising that Yao Guangxiao said such things.

Zhu Di said with a firm expression: "I believe that Mr. He will definitely not be untargeted, and it should be no problem to blast these boulders with artillery!" ”

Yao Guangxiao dissuaded: "Your Highness, I think you have a little too much trust in Mr. He, you and I have seen the power of the artillery before, even if Mr. He transforms the artillery, it will not be ......."

Zhu Di interrupted: "Okay, monk, don't persuade me, if it doesn't work, try it first, anyway, we don't have any other way at present!" ”

Yao Guangxiao sighed and didn't say anything more.

……

Soon, the artillery was pushed in front of the boulder pile by the people of the Institute of Chemistry.

The Institute of Chemistry was built by He Qiu to study the composition of zhayao, and the people recruited in it were strange.

There are folk fireworks craftsmen, and there are Taoist priests who study pills.

The similarity of these people is that they are poor, so they will be recruited by the palace.

After all, the treatment given to them by the palace is still quite generous, enough to make them worry about food and clothing.

After they entered the Institute of Chemistry, they basically followed He Qiu's instructions to do experiments.

Although they eventually worked on the shells, they did not know exactly how powerful the shells were.

This time, King Yan asked them to use artillery to blast away the boulder, and they were also a little apprehensive.

Yao Guangxiao observed the worried expressions on the faces of these people, and said to Zhu Di again: "Your Highness, you see that these craftsmen have little confidence, it seems that Mr. He really exaggerated the power of the artillery this time!" ”

Zhu Di didn't say anything, but shouted at those people: "Hurry up and open fire, don't delay the march!" ”

The group at the Institute of Chemistry received the order and hurriedly began to prepare.

Loading shells, adjusting ballistics, aiming, this series of actions they have practiced many times and are very skillful.

Soon, the preparatory action was completed.

Twenty men dressed in robes raised torches and lit the fuse.

With a loud bang, the cannon was ejected and fell on the boulder.

In an instant, rocks splashed and dust overflowed.

When the dust fell, everyone's eyes widened.

I saw that the boulder pile in front of me was gone, and only a pile of rubble remained.

The power of the cannonball was so great that it shocked everyone.

Only Zhu Di was very happy.

He squinted at Yao Guangxiao and said, "Monk, do you see it?" This is the power of the cannonball that Mr. He has modified, is it strong enough? ”

Yao Guangxiao swallowed a mouthful of saliva, feeling a hot pain on his face.

It's too a slap in the face.

He was still questioning He Qiu's braggaking just now.

Unexpectedly, He Qiu had already put wings on his cowhide, and it had all come true.

"Mr. He is indeed a man among the gods, and the power of this cannonball ...... It's strong enough! ”

Yao Guangxiao said to Zhu Di with a smile.

Zhu Di suddenly laughed and said: "It's rare that you have been convinced once, monk, or Mr. He is amazing!" ”

After speaking, Zhu Di said to the group of people from the Institute of Chemistry: "You put away the artillery, go to the middle of the team, and in the next march, if you need anything, you can tell me directly!" ”

Now this group of people from the Institute of Chemistry has become Zhu Di's treasure, and they must be protected.

As far as the power of this artillery is concerned, if Fengtai is guarded, no matter how many people come from the Northern Yuan, it will basically be difficult to break through.

After listening to Zhu Di's words, the people from the Institute of Chemistry probably also felt valued.

They quickly gathered the guns and transported them to the middle of the line.

The Pro-Guards also took the initiative to protect the people of the Chemical Research Institute.

Regardless of the era, artillery is an important branch of the army that needs to be protected.

When the people from the Institute of Chemistry stood in line, Zhu Di opened his mouth and shouted: "Now that the boulder has been blasted open, everyone hurry up and strive to reach Fengtai as soon as possible!" ”

After speaking, Zhu Di rode his horse and whipped forward at a gallop.

Yao Guangxiao and those pro-guards immediately followed.

……

On the other side, Yanwang's Mansion.

Zhang Ning had already explained the knowledge of agriculture to Zhu Gaochi and other three children for half an hour.

Under the scorching sun, the three children were sweating and their lips were dry.

Although they are not doing farm work, they have already felt some of the hardships of the farmers.

Princess Yan achieved her goal, and after thanking Zhang Ning, she took her three children and He Qiu to the courtyard of the East Wing.

She really wanted to try if this flower water was as magical as He Qiu said.

Only if I have tried it first, can I recommend it to those officials' relatives.

Soon, a group of five people arrived outside He Qiu's gate.

Because there was a instant noodle making machine, a beer making machine and a luxury lunch making machine in the house, He Qiu excused himself that the house was too chaotic and did not let Princess Yan and others in, and only entered the house by himself.
