After finalizing the type and quantity of the exchange of the experience scroll, Shang Ji glanced at his national battle points, and his face suddenly darkened.

Because there are quantitative restrictions on many things exchanged by merchants, according to the rules of the system, the points must be temporarily deducted first, regardless of whether the transaction is completed or not, so the points of merchants at this time have dropped directly from one billion to eight hundred and forty million!

Gritting his teeth, Shang Ji returned to the previous interface and chose to exchange for Huaxia City. Then his total number of points plummeted from nine figures to eight figures, leaving only a measly 40 million!

"Why am I so poor!"

Looking at the pitiful number of points, Shang Ji let out a lament that would make the lungs of other players explode.

But lamentation to lamentation, exchange must continue.

Although there are many things in the system exchange list, most of them can be made by the Pingzhou Army.

For example, the heaven-level equipment that makes ordinary players envy and drool, after Hephaestus joined the Pingzhou Army, Pingzhou has been able to produce heaven-level equipment stably.

Although the output is not very high, only three or five pieces a month, it can also ensure the normal replacement of the Pingzhou army, and sometimes even save some reserves.

The main reason is that Hephaestus is not very interested in this kind of "low-end" manufacturing, and every time he hastily gets a few tasks to deal with, and the merchant can't force people to work, otherwise the output will be two or three times more than a problem.

Or the elixir that ordinary players can not find, this kind of elixir that can help players break through the bottleneck of super-first-class is very sought-after among high-end players, and there are not a few people who break their heads for one of these elixirs.

However, in the Pingzhou Army, as long as the strength reaches the peak of the first-class generals, they can exchange their merits for a Nine Ox and Two Tiger Pills. Even if the merit is temporarily insufficient, the merchant also provides "loans", "installments", "credit" and other services very intimately.

Even at a higher level, it is regarded as an unavoidable pill, and taking one pill can break through the shackles of top generals - Breaking Heaven Pill, the Pingzhou Army has a stable output of more than ten pieces every year.

If it weren't for the shortage of raw materials (peach), the output of Potian Dan would definitely be more than that.

In general, except for a very few special items such as unique books, artifacts, and titles, there are really not many things on the exchange list that can attract the attention of merchants.

Picking and choosing, Shang Ji also found a lot of interesting good things.

For example, the wooden cow and the horse are made pictures!

When it comes to the wooden cow flowing horse, people's first impression is the god of the Three Kingdoms Zhuge Liang, whether the wooden cow flowing horse that the system provides exchange and Zhuge Liang's wooden cow flowing horse are the same thing, Shang Ji is unknown, but the powerful function of this wooden cow flowing horse still makes Shang Ji's eyes shine!

In the actual history of the Three Kingdoms, excluding some mythological factors, the wooden ox and the horse are a kind of manpower or animal powered cart with reasonable design and relatively lightweight.

But in the beacon fire, this wooden ox flowing horse is much more advanced. According to the introduction of system attributes, the wooden ox flowing horse does not need additional energy supply at all, only needs a driver to operate, can carry a hundred stones of goods a day thousands of miles, in an emergency, if regardless of mechanical damage and energy consumption, but also a significant increase in speed!

Moreover, this wooden oxen and flowing horse can travel on a variety of complex terrains such as mountain roads, swamps, and snow, and the speed will not be greatly affected.

You can even ignore some of the creeks and rivers and wade through the water!

After the limitation of space equipment during the National War, Shang Ji has keenly felt the change in the system's attitude towards space equipment, and this restriction may become more and more common, or it may directly become a rule.

Shang Ji also began to take precautions and set up a special baggage force. However, most of the carts they use are drawn by oxen and horses, and the carrying capacity and speed are low, and they are also severely limited by road conditions.

The appearance of the Wooden Ox Flowing Horse can be regarded as providing a new choice for Shang Ji, and without much hesitation, he directly spent 800,000 points to exchange the drawings of the Wooden Ox Flowing Horse.

In addition to the wooden ox and flowing horse, Shang Ji did not forget the naval army led by Ling Cao. It cost 1.2 million points to exchange more than 300 drawings of various types of sailor equipment. From the new warships that are more than 100 zhang long, to the bows and crossbows suitable for sailors, all of them are included.

In addition, Shang Ji also spent a full eight million points to help the sailor exchange a super-large warship as a new sailor flagship, although the sense of presence is not particularly strong, but Shang Ji has never forgotten the construction of the sailor. In his strategic planning, the sailor occupies an extremely important place.

At the same time, Shang Ji also exchanged a kind of formation diagram.

This formation is not a profound attack or defense formation, according to the introduction of the system, this formation is called the Condensing Spirit Array, which does not have any attack ability, and the only effect is to condense the aura scattered between heaven and earth into spirit crystals.

Lingjing is no stranger to businessmen, war puppets, communication stones, etc., are driven by Lingjing, and the wooden ox and flowing horse are also powered by Lingjing.

The production of spirit crystals before the Pingzhou Army was very primitive, relying on the artificial condensation of Taoist priests under the command of Huangyang Daoren. Not only is the efficiency low, the energy storage capacity is small, and the specifications of the spirit crystals produced are also different. Supplying communication stones is okay, but being used as a power source for war golems is a bit reluctant.

The Spirit Condensation Array is different, not only is the efficiency far superior to manual production, but also the specifications are uniform, and the spirit crystal energy storage capacity can be adjusted independently.

In addition to the large investment at the beginning of the arrangement, the daily maintenance cost after that is much lower than that of manual production, and in the long run, the cost performance is far greater than that of manual production.

The formation diagram of the Great Condensing Array only cost 10,000 points each, and Shang Ji exchanged a hundred copies in one go, as well as the materials needed to arrange the Great Array.

As the core of the formation, each formation can only be arranged with one spirit condensing array, but the scale of the formation can be large or small, depending on the investment in the initial arrangement.

The smallest can only cover a radius of one kilometer, but the largest can form a super large array with a diameter of 100 miles. The larger the scale, the higher the production efficiency, and of course, the corresponding maintenance cost and initial investment are also larger.

Moreover, according to the introduction, the Great Spiritual Formation will absorb the spiritual energy within the formation range, and the long-term passage of spiritual energy in the area will lead to barren land and sparse vegetation, and if there are people living within the formation area for a long time, it will also lead to a weak physique of the residents. Therefore, the location of this formation must be cautious.

Out of the psychology of being prepared, when Shang Ji exchanged the array materials, they were all exchanged according to the highest standards, and the hundred array maps plus the corresponding materials cost a full four million points.

After hesitating for a moment, Shang Ji exchanged for another fifty copies of the artifact and special equipment production drawings, and the prices of different types of production drawings were high and low, with an average of about 100,000 points.

However, the difficulty in making artifacts is not in the drawings, with Hephaestus's ability, it takes some time and effort to make artifact production drawings independently.

There are two real difficulties in creating artifacts, one is the candidate, and the other is the material!

Not to mention the candidates, only a god-level blacksmith can create an artifact, and as long as the grand master independently creates an artifact, then he will be immediately promoted to a god-level blacksmith.

As for the second point, the scarcity of artifacts and the difficulty of finding suitable materials are definitely one of the key factors (of course, the high failure rate of crafting is another key factor).

Shang Ji spent sixteen million in one go, exchanging a large number of high-grade materials that are rarely seen. This includes not only the precious ores used to craft equipment, but also some special materials for special buildings.

At the beginning, Shang Ji canonized Suzaku as a Zhenguo Divine Beast, and the system rewarded a blueprint for a special building [Vermilion Bird Pavilion], but many of the building materials needed in it Shang Ji had never heard of it.

A small number of people don't even know what a metric ruler is.

Just now, Shang Ji inquired, and the required special buildings are actually on the system exchange list, but the price is extremely unfriendly.

The most expensive is phoenix wood, which costs one million points!

Fortunately, in addition to the phoenix wood, the others are only more than ten or two hundred thousand points, and Shang Ji can still bear it.

After a careful inspection, Shang Ji found that there were no more special items worth starting, and he decisively exchanged all the remaining millions of points for precious medicinal materials.

There are many medicinal materials produced in the Dragon Roar Mountain Range, but the supply of some scarce medicinal materials depends entirely on luck, and taking advantage of this opportunity, Shang Ji plans to reserve a batch.
