The two went to the glass workshop, Xia Hongsheng drew a pattern, and taught the shopkeeper of the glass workshop to arrange to make glass bottles. After the order, before leaving, he also picked up a number of ready-made ones and asked the shopkeeper of the glass workshop to send them to Jingyang.

When they came out of the glass workshop, the two of them didn't go anywhere else, and went straight back to Jingyang.

The shopkeeper of the glass workshop did not dare to be slow about what Xia Hongsheng ordered, and it didn't take long for Xia Hongsheng and them to go back to Jingyang, and in the evening, the glass bottles selected by Xia Hongsheng were sent to Jingyang.

"Be careful, don't break it." Xia Hongsheng commanded the family members to put down the glass bottles, and there were a hundred and ten of them.

"Lang Jun, what are you doing with these glass bottles?" Xu Hui watched from the side and asked.

"Make one thing." Xia Hongsheng said mysteriously, after that, he looked at the glass bottles again, and explained to the person who sent them: "These glass bottles are just barely usable, go back and explain to the shopkeeper, I will draw the kind for him, and let him arrange to do it as soon as possible." ”

The little guy who brought the glass bottle saluted and left.

"Qi Yong, you go and call the carpenter, ask him to measure the mouth of the bottle, and go and make the cork." Xia Hongsheng commanded.

"Okay!" Qi Yong agreed, and went to Zhuangzi to find a carpenter.

After Qi Yong left, Xu Huicai asked again: "What is Lang Jun going to do?" ”

"A food that can be stored for a long time without spoiling – well, maybe it's more like a way to store food." Xia Hongsheng thought for a while and said to Xu Hui: "People who go far away, or who don't have green vegetables and fruits during the winter, this thing comes in handy." When the time comes, you will be able to eat Jiangnan plums in winter. ”

Xu Hui likes to eat green plums, but unfortunately he can't eat them in winter. Xia Hongsheng cultivated a few in the greenhouse, but the fruit was not as delicious as the one born in Jiangnan in season.

What Xia Hongsheng wants to do is canned food.

For long distances and oceans, all kinds of canned food are indispensable. The conditions on the ship are not good, and the things carried are easy to perish, even if they bring food, they are just like in the army, and they can be stored for a long time without spoiling, and as for the type and taste, it is not demanding.

Because of this, the people on the ship fell ill because they could not eat fresh vegetables, fruits and other foods, and some even suffered from serious life-threatening scurvy.

In the original history, it was precisely in order to deal with the problem that the battle line was too long, and a large number of food would rot and deteriorate after being transported to the front line, that the method of canning was invented.

In fact, the method is very simple, that is, the food will be processed, matured, and then put into the jar, put the jar in a pot of boiling water, heat for a period of time, while hot, with a cork to plug the bottle tightly. Then, the gaps are reinforced with thread and all the gaps are sealed with wax to make the can. In this way, food can be preserved for a longer period of time without spoiling.

In fact, canning is to create a sterile environment for cooked food as much as possible, and to seal this sterile environment to prevent bacteria from outside from entering the process that causes food spoilage.

The method of sterilization, when making canned food in the soil method, is to boil it in boiling water, and if possible, it can also be sterilized with hot steam. Then wrap the cork with wax while it is hot, wrap the gap between the cork and the bottle mouth with a thread, seal it with a layer of wax, and let it cool naturally.

This process of sealing while it is hot and then cooling it naturally is actually a process of hot filling. The hot filling can further eliminate the bacteria on the inner wall, and the second is that after the hot filling and sealing, with natural cooling, the bottle can also form a vacuum-like environment - although this vacuum is only a relative vacuum, not a real vacuum, but it can still play a role in preventing the formation of bacteria.

In this way, the contents of the can can be preserved for a long time without spoiling and deteriorating, and to a certain extent, it retains its original freshness.

Ocean voyages, all kinds of vegetables, fruits, canned meat, is an important source of vitamins and various nutrients for the people on board, is the pillar and guarantee for them to maintain health.

In the next few days, after the carpenter had made the cork, Xia Hongsheng began to try to make canned food on his Zhuangzi. The method of canning is very simple, and in later generations, Xia Hongsheng also made canned yellow peaches himself, but now there are only more steps to sterilize and seal with hot steam.

It took several days to make some canned vegetables and fruits, as well as some canned meat.

After sealing the things, Xia Hongsheng specially arranged for two personal soldiers to guard outside the warehouse to prevent others from touching the cans. Prepare for a limit of three months to see the condition of the contents of the can after three months.

When you think about it, these two things are the most important. As long as these two things are properly prepared, as for the rest, there is no need to worry too much.

There are military doctors on board, alcohol, bandages, etc., which are common in the army, so there is no need to worry. There are also milk powder, meat floss and tea bricks, which can be brought. When you think about it, you can say that you are well prepared. After the sailors are dispatched, they can sail near the sea for a long distance, which can also avoid many natural disasters, or get some shelter in the event of bad weather at sea.

Thinking about it this way, this ocean voyage doesn't seem to be so terrifying.

As for the big food, Xia Hongsheng really didn't take it into account from beginning to end, and regarded it as a thing worth worrying about.

In the original history, Da Shi may be a fierce rival that can almost match Datang. But that is also on the premise that Datang itself is in chaos. Several encounters between Dashi and Datang in history, that is, the Battle of Hengros, due to the sudden betrayal of the soldiers, caused Datang to lose a battle. But it's just a battle, if it weren't for the Anshi Rebellion after Gao Xianzhi came back, and let him order his troops to fight again, the result would definitely be different. Even so, after the battle of Hengros, although Da Shi was victorious, he did not advance eastward after that, and did not dare to attempt to invade the Central Plains again, which can also be seen the combat power of the Tang Dynasty at that time.

And even more so now.

It is not at all the combat power of an era.

In Xia Hongsheng's eyes, Da Shi is actually not much different from Tianzhu.

Nothing more than ants and locusts. Tianzhu is like an ant, and the big food is like a locust, although the locust is bigger than the ant and jumps faster, but whether it is to step on the ant or the locust, it is only one kick after all.

If there is nothing to worry about in the ocean voyage itself, then there is nothing to worry about in this trip.

Time has passed, and the good news sent back from Tianzhu is also one after another.

It only took Niu Jinda a month to defeat the Tianzhu coalition army, and then drove straight in, covering all the way down from north to south. Cheng Zhijie went all the way to the southwest and quickly occupied Bassine, that is, the part of Bombay in the later world.

After occupying there, Cheng Zhijie no longer attacked, but stationed troops to build a port, and let Niu Jinda lead the Tang Dynasty's iron cavalry to rush and kill all over Tianzhu.

A battle to conquer Tianzhu, which was originally quite powerful, ended so painlessly. 9110
