I'm a useless prince, so what if I know a little bit of chemistry?

When Chu Hu heard this, he knew he didn't have to keep adding dry grass to the fire. He was so happy that he almost jumped up. Without saying a word, he immediately went to the pile of firewood to get some firewood.

Lin Fan was quite happy to have some free time at this time, so he ordered people to bring out chairs and tables. He sat on a chair, drank tea and closed his eyes to rest.

At the same time, Lin Fan also began to consider his future development path.

With this simple method of purifying crude salt, Lin Fan is naturally confident that he can take down the Shen family and gain a good loyalty value.

After this, Lin Fan had to consider his future progress.

First of all, Lin Fan naturally had to hurry up and get out a series of things including soda ash.

After all, whether it is refined salt or soap, it is impossible to enter the high-end market by doing this alone.

After all, whether it is soap or salt, Lin Fan does not intend to always focus on the rich. In this world, common people still account for the majority, so these two things will eventually reach the people.

However, before it can be introduced to the general public, Lin Fan must first produce a substitute.

All of this seems to be a long process. Although Lin Fan feels that it is not difficult to do, it is full of difficulties when it comes to implementation.

However, Lin Fan was not afraid, even if it was difficult.

……

At the same time, in the heart of the grassland.

"General, there is a new tribe ahead. It looks like we are about to slaughter a fat sheep."

Looking at the tribe only a mile away from him, Nian Gui couldn't help but nodded.

The tribe in front of him was much larger than all the tribes Nian Gui had seen since entering the grassland. There were thousands of yurts here, so the number of people in the tribe must be considerable. If he could successfully inflict heavy damage on this tribe, there was no need to worry that the Huns would not feel any pain.

"Send someone over to secretly capture the spy. We are in the heart of the grassland now, so we can't be careless." Nian Gui said to the people around him.

"Yes."

Nian Gui did not immediately order a charge, but instead planned to test the strength of the tribe in front of him first.

"General, I don't think the Huns knew how to set up a false formation. We have been as fast as lightning since we entered the grassland. How could they detect us? If we charge over now, we will definitely be able to wipe out the tribe in front of us in an instant."

Standing on the other side of Nian Gui was a young-looking soldier, who was one of the adjutants who replaced Xiang Long and Chu Hu, and was one of the Nian family's death warriors.

However, his suggestion was immediately rejected by Nian Gui.

Nian Gui didn't look at him, but kept looking at the tribe in front of him, saying: "We only have so few people and no supplies. If we are ambushed, it will be troublesome. How can we be so careless?"

The more Nian Gui thought about it, the more he felt something was wrong, but he didn't know what the problem was for a moment. He could only frown and keep thinking.

About an incense stick of time later, the scouts sent by Nian Gui quietly came over.

"General, we have investigated carefully. It is not an empty camp. There are people hiding inside. It's just that I haven't caught the tongue. Please punish me, General." The scout apologized.

"You are innocent." Nian Gui replied absentmindedly.

Based on Nian Gui's intuition from years of combat experience, there seems to be something wrong here.

"General, shall we charge?" the adjutant asked impatiently.

Nian Gui also hesitated.

But General Nian was General Nian after all, and he made a decision after just a brief thought.

"Tell my brothers to be smart and keep their eyes open. Once you notice something wrong, retreat immediately without making any mistakes." Nian Gui ordered softly.

"Yes."

Nian Gui led his men to charge towards the tribe in front of them. Since they were a cavalry team of 5,000 people, their charge was naturally as powerful as thunder.

In just a moment, they had reached the edge of the tribe.

The people in the tribe seemed not to hear the sound of horse hooves, and no effective response appeared.

Nian Gui began to recall the events that had happened on the grassland in the past few days, and all kinds of mysteries continued to brew in his mind.

"No!" Nian Gui suddenly shouted.

He seemed to remember something and waved hurriedly, signaling the cavalry to stop.

At this moment, some soldiers had already run into the yurt, but then ran back in a hurry, because the yurt was empty at this moment, without a single living person.

"General, this is terrible. We may have fallen into a trap. There is no one inside!"

"General, there's no one here!"

"Not here either!"

Nian Gui's head immediately buzzed and he realized what the problem was.

It went so smoothly, everything went so smoothly.

Since their entry into the steppes, only the first attack seems to have met with resistance.

But after that, they only encountered some old, weak, sick and disabled people who had no resistance at all.

At first, Nian Gui just thought that it was because all the young Huns were mobilized to the front line, which led to the fact that all the people he met were the old, weak and sick.

But at this moment, it seemed that their actions had probably been known to the Huns in advance.

No, it's not that I knew. It's impossible for the Huns to have such a powerful ability. The Huns should have been clear about my plan when I first entered the grassland.

There are Huns' spies in the court.

So who could this person be?

Thoughts flashed through Nian Gui's brain in an instant, and almost subconsciously, Nian Gui gave the order.

"Retreat quickly! Everyone retreat south!" Nian Gui shouted and gave his orders.

"Yes, retreat!"

But at this moment, a cold voice came from somewhere, and it seemed like a Yaksha ghost taking lives.

"You want to leave, can you still leave?"

The sound seemed to come from all directions, making it difficult to tell the direction.

"Whoever pretends to be a ghost, come out and get killed!"

Nian Gui shouted to the surroundings, but just a few seconds after he finished shouting, he saw arrows shooting from all directions. There were so many arrows that they could only be described as overwhelming.

"Withdraw! Quickly withdraw!"

Nian Gui knew that he had fallen into a trap, so he made a prompt decision to break out to the south.

After breaking through, Nian Gui discovered that a lot of Hun cavalry had surrounded him since he didn't know when.

"Damn it, break out!"

Nian Gui cursed and immediately ordered a breakout.

The five thousand cavalrymen led by Nian Gui rushed out like arrows.

"kill!"

Although they were surrounded, Nian Gui and others did not show any fear.

The two sides collided like two huge monsters, with blood and flesh flying everywhere.

Nian Gui waved the saber in his hand, and Hun soldiers kept falling in front of him.

"General, there are too many enemy troops. We can't charge!"

"General, what should we do now?"

The two adjutants, one on the left and one on the right, protected Nian Gui, who was now covered in blood.

Nian Gui also realized that something was wrong. There seemed to be too many cavalry on the opposite side, and his own cavalry could hardly run, and their speed had been greatly reduced.

The most important thing for cavalry is mobility.

As long as they lose their mobility, the cavalry will be just meat on the chopping board.

"Damn it, everyone turn around and break out to the north!" Nian Gui had no choice but to break out to the north.
