For the old woman, at this time, it is estimated that all the words of comfort are too pale, she guarded a thought, and waited for someone to come back, but in the end she only waited for a tomb, Wan Bingyu thought, and a sigh overflowed from her mouth.

Because the old woman's home was not far from here, at the invitation of the other party, Wan Bingyu and Heng Xinyuan went to her house.

I thought that the old woman would have a harmonious and happy family, but when they arrived at the place, they found that in fact, over the years, the old woman has not lived well, although she has a yard, but there is no furniture at home, and the only living person is her, Wan Bingyu felt distressed, so she asked: "...... you all these years"

The corner of the old woman's lips pulled out a bitter smile: "When I was young, because my appearance was ruined, so I didn't have the idea of getting married, and when my brothers and sisters got married, I moved here to live alone. ”

It seems that this woman was also a miserable person.

Wan Bingyu and Heng Xinyuan sat in the woman's house for a long time, mainly to talk to the woman about the old gentleman's life.

Hearing that the person she had been thinking about for many years was actually alive and well some time ago, tears slipped down the old woman's face, like a pearl with a broken thread, and she couldn't hold it back.

"He's so close to Minjin, but he hasn't come to me......"

"Maybe the old gentleman doesn't want to disturb your current life, mother-in-law, in fact, he still thinks of you, the hosta in your hand, he also has it, and it was hidden under his bed like a baby, but it was buried in the tomb when he was buried today, he has always treasured the hosta, and he must have you in his heart."

The old woman shook her head with a lonely expression and said, "It doesn't matter whether you remember it or not. ”

The left and right people are dead, and no matter how much they say, they can't change the established facts.

Just as they were sitting and talking together, there was a sound of hurried footsteps outside, and then a little boy about seven or eight years old rushed to them: "Mother-in-law, I came back from school, who are these two, are they your guests?" ”

The old woman's originally gloomy face softened slightly when she saw the little boy.

"Yes, they're guests."

Presumably this child is the adopted child that the old woman said just now, Wan Bingyu looked at him a few times, and found that the other party was also staring at him, and turned his gaze back with a raised eyebrow, and at the same time, the old woman also took the little boy away.

"We've been bothering my mother-in-law for a long time, so we won't continue to bother......"

Wan Bingyu and Heng Xinyuan glanced at each other and stood up together.

The old woman also stood up: "Wait a minute, I have something for you here." ”

As soon as the words fell, the old woman had already walked into the inner room, leaving only Wan Bingyu and Heng Xinyuan in the living room looking at each other, they couldn't think of what the other party was saying to give them, this woman was the object of the old man's heart, even if they wanted to give something, it should be them to hand over the old man's relics to the other party, right?

Their confusion did not last long, for the old woman soon walked slowly back to them with an object wrapped in cloth.

Wan Bingyu frowned and looked at the thing in the other party's hand, and from the shape, he couldn't guess what was inside: "Mother-in-law, this thing is ......"

"This is what I found in the rubble of their house many years ago, after the explosion, and there was a book in it, and I couldn't read or understand what it was, but some people in our town said it was related to bombs."

Wan Bingyu suddenly became energetic, when the explosion happened, the old man was just a young man, so it was naturally impossible to write notes related to the bomb, and the book in her hand may have been written by the old man's grandfather, that is, the first person to develop the bomb! These two men have very different ways of making bombs, maybe they can find some solutions in the books!

Wan Bingyu took the cloth bag handed by his wife and opened it to see that it was really an old book that had been yellowed!

"Ma'am, this old book is available?"

Wan Bingyu nodded with a smile: "Of course it works, although the notes left by the old gentleman and the method he taught me before are good, but because the old gentleman he ...... It's too early, so the production method is not perfect enough, with this notebook, maybe we can use another production method! ”

Heng Xinyuan keenly captured the key factor: "Madam, you want to make a bomb?" ”

"Yes, not only do I have to make bombs, but I also have to make bombs that are more powerful than the old man's bombs."

Only if the power of the bomb is enough, they can withstand the attack of the army of Pingyu and keep Liangzhou City!

Heng Xinyuan's expression became solemn after hearing those words, he moved his lips, he originally wanted to say something, but Wan Bingyu smiled on the corner of his lips, thinking about it, he still decided to go back and go again.

The old woman stood silently beside her, watching the two of them talking, and sighed with emotion: "It's good that this scroll is useful to you, but I was worried that you wouldn't need it before." ”

"No, with this scroll, we can make even more powerful bombs!"

Speaking of bombs, the old woman couldn't help but recall the past, it was also a bomb that was detonated, which caused Minzhen to be destroyed in half, her life, and the lives of many people in the town, were also destroyed because of this bomb, who would have thought that time would turn and turn, and in the end, the harmful object would become the key to defending the city?

The old woman sighed and shook her head.

Before parting, she told Wan Bingyu and Heng Xinyuan for the last time: "The power of the bomb is too great, you must be careful when developing the bomb, don't hurt yourself." ”

The explosion years ago had already scared the old woman.

Wan Bingyu knew what she was afraid of, smiled and took the woman's hand and promised, "I will definitely not let that tragedy happen again." ”

The old woman nodded. After they left Minzhen and returned to the barracks, the first thing Wan Bingyu did was to go back to his room to read the book, although the notebook was well kept by the old woman, but after all, decades have passed, the scroll has long been yellowed and brittle, and even in some places it will rot when touched, Wan Bingyu must be careful to turn the pages of the scroll.

Heng Xinyuan saw all this in his eyes and hurt in his heart.

Because Wan Bingyu's health was not good, the military doctor prescribed her a fetal pill, and now Heng Xinyuan was holding the boiled fetal pill in his hand, and when he entered the door, Wan Bingyu didn't even raise his head.

Heng Xinyuan asked with a headache: "Madam, you better rest first." ”

Wan Bingyu didn't raise his head and said, "No, I have to finish reading this book first, there is a very special production method recorded in it, I have to learn ...... as soon as possible."

Heng Xinyuan sighed, stepped forward and pulled the old book out of her hand with a very light but non-refusable force.
