This is a hidden valley, there is a small river next to it, and a large shed is set up by the river, some blacksmiths are tinkling and beating, Liu Yuan can see from the clairvoyant eyes, in forging, is a horizontal knife, spear and other relatively simple weapons, in addition to the shed, Liu Yuan also saw an earthen furnace used for ironmaking, but at this time there is no smoke, next to the earthen furnace, there is a huge hole, constantly people in and out.

If you guess correctly, it's the entrance to iron ore.

This valley is surrounded by mountains on three sides, there is only one way out, it looks quite hidden, mines, iron-making earthen furnaces, water sources, forging workshops, from digging out iron ore to forging weapons and equipment, one-stop service, eliminating transportation, and enough concealment, the design is very good, this is estimated to be the secret "arsenal" of Songtsan Gampo, he built it so hidden, Liu Yuan believes that the original intention is not to prevent the Tang army, but the lord with bad intentions.

From the establishment of the state in Tibet to the present, it is not uncommon for lords to rebel, and Songtsen Gampo is the lord under his hand, and he does not necessarily have complete trust, so it is not surprising that it is secretly built here.

"Brother Liu, how is it, are you sure?" Eldest Sun Chong asked in a low voice.

Liu Yuan asked rhetorically: "If you change the eldest grandson brother to attack, how sure are you?" ”

"At most, twenty percent" Changsun Chong said with a wry smile: "The guards here are so tight, there are clear posts and secret sentries, and the fortresses of the arrow tower are everywhere, rushing in rashly, the casualties will be very heavy, if you are not careful, our little people will have to fold here." ”

Liu Yuan was deeply impressed by Changsun Chong's words, where there is a forging workshop here, it is about to become a military fortress, not to mention anything else, there are more than ten arrow towers for archery alone, those soldiers. All of them are firm-eyed, steady and disciplined, obviously the elite of the Tibetan soldiers, the exquisite and beautiful chain mail, well defended the whole body, wearing a helmet on the head, only two eyes are exposed, the armor exudes the brilliance of metal, and the weapon shines with cold light, which looks very sophisticated.

The meat is fat, but there are bones in it. It's hard to gnaw.

"Yes, we need to think long and plan ahead." Liu Yuan said far away, and casually handed the clairvoyant to the wild wolf: "Big brother wild wolf, take a good look." Remember their directions, as well as the points of defense and the rules of patrolling. When the time comes, draw out the defense drawings. ”

"Okay." The wild wolf listened. knew that Liu Yuan wanted to fight it, so he didn't say much, answered, and took the clairmiles and observed them carefully.

Liu Yuan didn't have a good way for a while, so he asked the eldest grandson to slowly retreat down the mountain.

If you want to attack, you must completely annihilate the hundreds of people inside. At least double the troops, that is, more than 1,600 people, and now Liu Yuan only has 400 people in his hands, which is too far behind.

Return to the field camp of the Zhenfan Army. Liu Yuan and Changsun Chong immediately called the scout and asked about the situation, this is what the two of them meant, if they find Hou Junji, they will pass the news to him, and then they will end the forging workshop of Tufan together.

"See the two generals"

Soon, several scouts were ordered to walk in and salute on one knee.

Liu Yuan waved his hand and said, "Excuse me, the general will ask you, do you have any news of the general waiting for the army recently?" ”

The scout fire chief replied, "General Hui, my subordinates just wanted to report this important information to the two generals. ”

"Say it quickly," Changsun Chong said anxiously.

"Yes, my subordinates reported that more than 20 miles to the west, they found a special message left by General Hou's scouts three days ago, and a large army of Tubo was attacking and suppressing it, and it was coming soon, so the three generals acted expediently." The Scout Flame Master said respectfully.

Liu Yuan asked carefully, "How many people are there?" Who leads? General Hou, where are they now? ”

"General, none of this is left, only the information in front."

Liu Yuan and Changsun Chong looked at each other, and after careful inquiry, there were indeed no clues, so they were a little helpless to let the scouts go out.

Three days ago, it appeared near here, after three days, the plateau is vast, and now I don't know where to go, and there are about three messages for the scouts: one is to contact Hou Junji, and the goal of ending the forging workshop together cannot be achieved, and now I don't know where they are; The second is that the Tubo finally took action and sent a large army to suppress the Tang soldiers who were attacking unscrupulously in their hinterland, and the life of the Zhenbo army would be difficult in the future.

The last piece of information is a bit playful, and it is expedient.

Although there are only four words, but it contains a lot of content, the so-called expediency, can be dodge, can be attacked, can be harassed, and can even be said to retreat, from these four words can be seen, Hou Junji is satisfied with the current strategic goals and achievements, Liu Yuan, Changchong Sun and Cheng Huailiang's performance of the three young generals to the spear affirmation, now it can be said to be a laissez-faire for them, advance or retreat, but he is not satisfied, but also want to achieve greater results, otherwise, he directly summoned the three of them, waiting for the opportunity to retreat.

Finally got an opportunity, with Hou Junji's ambitions, absolutely not satisfied with the immediate interests and military merits, the Tubo Plateau is vast and sparsely populated, and the terrain is sometimes open and sometimes complex, which gives him a lot of detours and space for survival, it is where he can be used as a master tactician, he needs this battlefield, he needs this stage to prove himself, so Hou Junji will not retreat so quickly.

Liu Yuan said to himself: "It seems that if you want to destroy that forging workshop, you can only rely on yourself, and you have to complete it in these two or three days." ”

"Ah, why do you say that?" Eldest Sun Chong said in surprise.

"It's very simple, General Hou didn't even indicate where he went, there must be a big move, he can't draw manpower in the near future, from the defense of the forging workshop, the Tubo people attach great importance to it, as soon as their army arrives, they will definitely give priority to increasing the protection of troops, and it will be even more difficult to start at that time, so the action must be fast."

"Well, that's true, but unfortunately, we have too few troops." Changsun Chong shook his head helplessly.

"Forget it, take a good rest first, Brother Eldest Sun, your injuries haven't fully healed yet, let's wait for the wild wolf to scout well, and then think about it in the long run."

The two of them had no better way, so they had to sit in the camp and close their eyes and think hard to see how they could take down the forging workshop, it was best not to have too many casualties, Liu Yuan grabbed his hair, thinking that he had a few shells or a few machine guns or something, and it was estimated that he would not need half an hour to take down all of them, or a sniper rifle, although it was a little troublesome, it would definitely be no problem to take down this workshop that was armed like a stinger with zero casualties.

When it was almost dawn, the wild wolf came back, and what he brought back was a detailed defense map, the arrow tower, the sentry and the dark fort were clearly marked one by one, and even the patrol rules of the Tibetan soldiers were also explained in detail.

"Two generals, the little one sneaked into the forge after nightfall, and the situation inside was also figured out" The wild wolf pointed to the hand-drawn defense map and said: "There are about eight hundred and thirty people in it, there are one thousand household chiefs, one hundred households and five, divided into two batches, taking turns to rest, and the miners and blacksmiths who are mining are about four or five hundred people, eight or nine times out of ten are Tang people, many of them are soldiers, all of them were captured by the Tubo people, because they are afraid of the craftsmen escaping, so the guard is very strict, there are bells in many places, as long as they are pulled, It will alarm all the Tibetan soldiers. ”

"Oh, by the way, that Qianhu chief is very cunning, iron-making only starts at night, that place is remote and surrounded by mountains, so you can't see those black smoke, the vigilance at night is stricter than during the day, even if it is a night attack, it is difficult to succeed in one blow." Wild Wolf added.

Nima, forging during the day and smelting iron at night, the night is very good to cover up the black smoke that rushes to the sky, no wonder I haven't found it, it seems that I have encountered a difficult opponent.

It can't be attacked during the day, and it's heavily guarded at night, so there's really no way to take it.

Although they got the defense map, a few people still have nothing to do, as the saying goes, one white covers three ugliness, one force will drop ten, just such a little people, even if there is a trick, it is difficult to work, usually it can be grinded, a little bit of consumption of the strength of the Tubo people, but this time is different, when the reinforcements of Tubo arrive, then it will be a joint waiting for the king, it will be difficult to eat.

"Brother Wild Wolf, do you want to attack with fire?" Liu Yuan remembered the effect achieved by using fire attack last time, and hurriedly asked.

"It's useless, firstly, this house is mostly made of stone, which is difficult to ignite, and secondly, the place is close to a small river, and it is convenient to get water." The wild wolf shook his head and vetoed Liu Yuan's opinion.

The eldest grandson Chong's eyes lit up and said, "Otherwise, if we poison it, we will poison it in that small river and poison them all." ”

Liu Yuan shook his head and said: "This is also difficult, we have all seen that place, the water of the small river is a little urgent, it is living water, and it will be washed away after a while after poisoning, besides, do you have poison?" ”

"Nope"

The three of them proposed a few more methods, but they always felt that they were not sure, and they all vetoed them in the end

With a sound of "swish", the eldest grandson was so angry that he suddenly pulled out a horizontal knife, slashed at a stone next to him, and said angrily: "Oh, this doesn't work, that doesn't work, the fat on the side of the mouth has slipped away, it's really annoying to me." ”

Good guy, I didn't expect this guy's temper to be so big, it seems that the rabbit is in a hurry and bites people, this is right, Changsun Chong, who has always been good-tempered, actually took a stone that served as a cushion to vent his anger, which is really funny.

With a "swish", the knife cut down, and actually cut off a neat corner of the stone.

The wild wolf was taken aback, and then said with a little jealousy: "Good knife, cut gold and jade, cut stone like mud." ”

Changsun Chong was also taken aback, touched his knife and said, "No, my knife is equipped with the Zhenfan army, not a treasure knife with private belts, strange, how can it be sharp?" ”

It's strange, even if there is a treasure knife, it also takes strength to cut gold and jade, and with the strength of Changsun Chong, it's a bit nonsense, right? Liu Yuan curiously picked up the small stone that was cut off by the eldest grandson Chong, and looked at it curiously under the firelight, suddenly, Liu Yuan's eyes lit up, sniffed it before he got it to his nose, and then as if he was crazy, he laughed while jumping:

"Ha Lu Ha, Ha Lu Ha" (To be continued......
